　　 Greenhouse materials will inevitably wear little by little during long-term use. The limit of this wear, the standard parts of machinery is the service life of vegetable greenhouse materials. The durability of the greenhouse is affected by factors such as the aging resistance of greenhouse materials and the carrying capacity of the main structure of the greenhouse.

Transmission mode: The agricultural greenhouse monitoring sensor network of the chain rotation shearing machine includes four points: the collection of plant growth parameters, data fusion, data transmission and monitoring data processing. There are many types of pipe bending, so there are also many greenhouse pipe bending machines.
 
　　 Of course, for light-transmitting materials, there is also a self-consuming process. In addition to the strength of the light-transmitting material, the durability of the light-transmitting material is also manifested in that the light transmittance of the material continues to decay with time, and the degree of light transmittance attenuation is a decisive factor affecting the service life of the light-transmitting material. The frame of the greenhouse pipe bender, etc. with a small load usually adopts square or rectangular section low-carbon steel welded steel pipe, and the frame of the large-loaded plough, chisel plough, disc plough and disc harrow uses low Alloy manganese steel pipe. Keep away from units and places that cause environmental pollution, distance: general large-scale greenhouses and residential areas:>
 
　　M. According to the classification of the transmission side, it can be roughly divided into four categories, one is manual, the second is pneumatic, the third is mechanical transmission, and the fourth is hydraulic transmission. Therefore, according to the application characteristics and technical requirements of the above four points, the following design criteria should be considered in the overall system design: (1>
 
Time continuity criterion The growth of plants in agricultural greenhouses has a long physiological cycle, and the time when the environment is abnormal and the disease occurs during plant growth is random. Therefore, the sensor node maintains continuous monitoring for a long time, and the life cycle of the network is One of the issues to consider. Adjust the required position and angle of the elbow. Power: 3kw Please pay more attention to what I think is right, there is one more. Gasoline engines are characterized by light weight, good low-temperature starting performance and smooth running. They are mostly used in small agricultural machinery, such as rice transplanters, portable plant protection machinery and tea pickers. Shearing knife: made of Cr12 material, quenched at high temperature, composed of two blades
 
　　The main structure of the vegetable greenhouse is mainly affected by man-made destruction and natural influence. It is an indispensable condition to heat the arched greenhouse frame with a few steel bars. According to the classification of the controller, it can be roughly divided into four categories, one is manual control, the other is semi-active, the third is active, and the fourth is CNC. Reliability criteria Because the environment of agricultural greenhouses is complex and changeable, environmental factors such as plants, landforms, and nodes will interfere with the transmission of monitoring data. Therefore, the wireless sensor network monitoring system of the agency guarantees the accuracy and real-time transmission of data, and avoids The lack of monitoring data causes misjudgment and omission of the monitoring personnel. Adjust the positioning of the machine to the required length. Forming system: 3Kw pumping station, shear setting greenhouse necking machine has complete functions and is widely used. According to the regional fuel supply situation, gas generators using gas, petroleum-associated gas, liquefied petroleum gas and producer gas as fuel can also be used according to local conditions. Press plate thickness: 0.5mm The forming part of the color steel feeding rack with random attachment is divided into precision wheel rotation forming, the forming effect is good, the friction between the wheel and the material is reduced, and the debugging is convenient and fast. Adjust the vertical lifting guide rail, the bending pipe makes the guide mold pressing cylinder move forward to tighten the iron pipe. Network robustness criteria Sensor nodes continuously collect data related to plant growth. At the same time, some sensor nodes act as routers in the network. They not only need to transmit data collected by themselves, but also forward monitoring data of other nodes. Node energy is bound to It will be exhausted quickly until death, and the wireless sensor network cannot be paralyzed due to the time continuity criterion. Therefore, redundant sensor nodes are used as nodes to join the network, and the network must be robust.
 
　　 Snow cover and lack of maintenance during user use will promote its aging and reduce its carrying capacity. With the continuous rise of energy costs and the increasing pressure of environmental protection, whether it is traditional coal, gas or oil heating, or new solar, geothermal, and electric heating, they all encounter the double of cost and environmental protection. Pressure and energy saving have become the primary problems solved by greenhouse production. At the same time, it requires convenient transportation and convenient connection with the main traffic line. Hardware robustness criteria According to the growth of the plant, artificial or automatic plant feeding is often carried out, and the node is bound to be stained with nutrient solution, so the performance and sealing of the sensor node are good, otherwise it will cause a short circuit of the node and burn the node. The clamping cylinder can be iron pipe. CNC system PLC panel, KEL-320 display counter adopts domestic photoelectric rotary encoder. Greenhouse card slot machine is a supporting product for the greenhouse bracket. The card slot produced by it is used in the greenhouse construction with the greenhouse bracket. The greenhouse shrinking machine does not damage the zinc layer. Diesel engines and gasoline engines can also be modified to use gaseous fuels such as coal gas, or they can be converted to dual-fuel internal combustion engines that use coal gas and are ignited by diesel as agricultural power machinery. Mainly used for processing heat exchange products. Standard parts mechanical slot machine parts represented by laser welding have achieved great breakthroughs and development in advanced welding technology. Laser has the characteristics of strong monochromaticity, strong directionality and high brightness. It can be used as a heat source for welding metals.
 
　　 Therefore, when constructing vegetable greenhouses, appropriate greenhouse materials and greenhouse main structures must be selected. The solar greenhouse in China has successfully achieved the feat of producing thermophilic fruits and vegetables through the winter without heating or only temporarily heating in the north latitude °~°. The use of cold-bent channel steel or crimped channel steel made of thin steel plate to manufacture planters and field cultivators can significantly reduce the weight compared to the use of hot-rolled steel frames. Follow hardware robustness guidelines when designing node hardware. The normal operation is to put the workpiece into the bending mold, and the front end is in contact with the positioning, step on the foot switch to complete. Laser welding is to project a focused laser beam with high energy density on the metal material to be welded, and convert it into heat energy after being absorbed by the material, which is used for melting and welding of metal materials. (Can produce: round, rectangular, elliptical, special-shaped, plastic plating, solid, hollow and other greenhouse frame products, the length, arc, height, span, thickness can be adjusted at will. Motors are mostly used to drive fixed operations or indoor operations All kinds of agricultural machinery, such as agricultural products processing machinery and water pumps, as well as various operating machinery in greenhouses, warehouses, and livestock houses. What are the preventive measures for automatic pipe benders? The automatic pipe benders must be well grounded and have copper wires. The cord is not allowed to be connected to the power supply voltage above the defined range, plug-in plug-in plug-in plug-in plug-in plug-in plug-in plug-in plug-in plug-in plug-in plug-in plug-in or pull out the connector, do not pull the wires or cables, lest they are torn off by welding. Laser The thickness of the welded parts can be in the range of several microns to 50mm. When operating the CNC pipe bender, you must focus on your mind. It is forbidden to put your hands or other objects in the work area. In case of emergency, press the emergency stop button and then turn Turn the torsion switch to the manual position, and the standard part machinery is manually reset. If the pipe is bent, report for repair in time.

These demands drive the use of all-electric pipe bending technology bolt cold heading machines

[According to a report by Aviation Manufacturing Magazine in April 2014] Aviation pipe fitting manufacturer SL Engineering (SLE) continued to invest in advanced automation technology and purchased a second all-electric CNC pipe bender from Unison. The new machine tool enhances SLE's manufacturing capabilities, especially the ability to produce more flexible tubular shapes, and also expands the size of all-electric servo-controlled bendable pipe fittings to 80mm. SLE said: "The advanced forming capabilities of the tube bender give aircraft and engine manufacturers an advantage to deal with more complex shapes and more challenging bending radii to reduce weight, save space, and eliminate welded joints. Unison machine tool bending Ability to better control the thrust of pipe fixtures and brackets helps us achieve higher accuracy." SLE's business requires greater manufacturing flexibility. There are about 5-25 parts per batch, and the cold heading machine order may only have one urgent aircraft part. Higher accuracy and complexity of appearance are another aspect. Until recently, very few pipe fittings required a bending radius within 2D (2 times the pipe diameter). However, today, SLE continues to receive requirements for bending 1D, and the straight edge section between the bends of the cold heading machine is still required to be small. The use of thin-walled pipe fittings and expensive materials such as titanium alloys and nickel alloys for cold heading machines are also a trend.　　 These demands drive the use of all-electric bending technology. SLE installed a 30mm diameter Breeze model in 2010. The new Breeze80 has a elbow diameter of 80mm. The machine tool has also added multi-batch/multi-radius tooling capabilities. This is very important for forming some complex tubular shapes and multiple bending sequences.　　 For example, the shape of a military aircraft part requires multiple 2D bends, with as few straight sections as possible between the bends, and thin-walled titanium alloy pipes are used. The ellipticity after bending should also be less than 5%, and the position and length tolerance after bending and welding should reach ±0.005 inches. Since the parts are made of titanium alloy, the bending must be correct once, otherwise it is almost impossible to adjust after forming. The uniformity and repeatability of the Unison machine tool is critical to manufacturing this part.

Introduce how to ensure the stability of mechanical operation when installing a cold heading machine

1. In mechanical lifting, two cables with a diameter greater than 25 should be used for lifting. The cold heading machine is a special equipment mainly used for mass production of fasteners such as nuts and bolts. According to the theory of metal plastic deformation, the bolt cold heading machine applies a certain pressure to the metal blank at room temperature to cause plastic deformation in the mold cavity and form it according to the specified shape and size. A pair of bevel gears are installed on one end of the crankshaft for standard parts machinery, a cam device is installed on the driven bevel gear shaft, and a scissors slider is installed vertically on the roller shaft of the driven roller of the cam device. The utility model overcomes the shortcomings of the prior art, and the running friction coefficient and impact force between the various parts of the feeding and cutting mechanism are small, so that the equipment runs smoothly, the running noise is effectively reduced, and the product quality and productivity are greatly improved. First, open the operating door cover of the machine and the upper cover behind the main sliding platform. The wire rope should be hung on the four corner booms of the machine platform. The angle of the lugs should not exceed 60 degrees. When lifting, it must be noted that the lifting lugs should not collide with the mechanical parts and the casing. 2. The second step. During installation, attention must be paid to the level of the unit in the front and rear and left directions to ensure the stability of mechanical operation. 3. The cold heading machine is equipped with a pneumatic clutch brake. Before the mechanical air pressure three-point combination, the air pressure storage container should be set up. The two containers can be shared or used separately. For specifications, please refer to the air consumption table of the SR clutch inch motor school bus. 4. The mechanical power distribution and installation cables should not be smaller than the main switch cable on the mechanical control box. At the same time, the motor and the electrical control box must be grounded separately to avoid damage to the machine and personnel when leakage occurs. 5. Lubricating oil or pressure oil should be added before mechanical operation. The lubrication system should explain the volume and viscosity index of the oil. 6. Before starting up, check whether the wire connector is loose and whether the screws of each machine are loose. After the machine has been running for a period of time, recheck whether the screws of each part are loose and whether the oil circuit is unblocked. Chapter VII. To start the machine, first start the lubrication pump. The blue indicator light must be turned on to indicate that the lubrication pump is operating normally, and then the main motor is started. At this time, the air pressure needs to reach 5.5-6.0kg/c. First, move the machine in inches to check whether the machine runs smoothly, and then check whether the stroke is normal. In order to check whether it is normal, the main sliding platform must be at the rear when the machine is stopped for single stroke and general operation. Otherwise, the cam angle position of the electrical appliance controlled by the parking space must be adjusted, which needs to be adjusted due to different speeds. In inch operation, the interval time per inch is greater than 2 seconds, so that the clutch will not be abnormally worn. When the machine is equipped with a gear shifting device, the machine tries to work at a low speed to reduce the sliding wear of the clutch when it is running at high speed.

The influence of material modification of cold heading machine on product quality

The effect of material modification of cold heading machine on product quality The adjustment of material structure has a great impact on product quality. The head defects of anchor rod parts and the crack defects of cold head machine parts are the main waste phenomena in the production process of cold heading machines. Part of the reason for these defects is the material preparation process. According to the theory of metal plastic deformation, the bolt cold heading machine applies a certain pressure to the metal blank at room temperature to cause plastic deformation in the mold cavity and form it according to the specified shape and size. A pair of bevel gears are installed on one end of the crankshaft for standard parts machinery, a cam device is installed on the driven bevel gear shaft, and a scissors slider is installed vertically on the roller shaft of the driven roller of the cam device. The utility model overcomes the shortcomings of the prior art, and the running friction coefficient and impact force between the various parts of the feeding and cutting mechanism are small, so that the equipment runs smoothly, the running noise is effectively reduced, and the product quality and productivity are greatly improved. The cold heading machine is a special equipment mainly used for mass production of fasteners such as nuts and bolts. Reasons and control of bolt fracture According to the national standard GB3098.1, the bolts of the cold heading machine should undergo a head hardness test without heat treatment. In the test, the fracture of the bolt head is called fracture. There are two types of broken ends: cracks caused by the interlayer of the head and the joints or adjacent parts of the head and the rod fracture. The reason for the cracking caused by the interlayer of the workpiece head is relatively simple, and it is generally caused by improper cold forging machine technology. When the center position of the punching method and the concave shape of the front punching process are improperly adjusted, the head and the rod of the front punch have different shafts, and the head forms an obvious tilt, which will produce waste during formation. If the diameter of the wire is small, the forging ratio is increased. Vertical bending is prone to occur during fracturing, leading to metal streamline turbulence, separation of organic connections between crystal grains, and breakage. For the head caused by improper processing of the cold heading machine, as long as the process design can be improved. The fracture of the head joint is partly due to the fidelity of the material reforming process. Production practice and experimental research show that the cold deformation properties of steel play a decisive role in the quality of the workpiece. The quality of steel consists of two aspects: First, the steel performance of the steel mill must meet the requirements of the steel for the cold heading machine; on the other hand, the steel must help protect or improve the performance of the steel cold heading machine during the reforming process. The common defects in the original structure of steel are: there is a serious segregation zone in the steel, and the concentration of non-metallic elements such as carbon, phosphorus, and sulfur in the segregation zone reduces the cold deformation performance of the steel and causes deformation of the workpiece. actual. Generally speaking, rimmed steel is prone to segregation. There are defects such as shrinkage cavities, pores, and inclusions in the steel, or the superheated structure with coarse grains, which shows brittleness. In the process of material reorganization, due to improper process management, the factors that cause steel defects include: hydrogen embrittlement of steel during the pickling process and brittle fracture caused by overheating during the annealing process. When the tensile deformation in the material structure is within the critical deformation degree, when the crystal annealing results in a larger grain thickness, the head phenomenon will also occur. When the deformation of the head and the workpiece rod are greatly different, the degree of work hardening caused by the difference is large, and the joint of the head may be broken when the strength of the head joint is low. For example, the thick tracking process of the grooved hexagonal bolt is less damaged than the fine tracking process, and the process of the cold drilling machine of the groove is smaller than that of the cold drilling machine. This is due to the poor strength of the original head rod and fewer interruptions in the production of small and medium products. This is because the properties of the materials used in small-sized products are improved after repeated rolling and drawing.
