Guangxi Zhuang Autonomous Region Leye County 2020 roll machine products exhibition
 Mechanical three roller asymmetric bending machine is the main unique bending machine is its place: its structure is three roller asymmetric, the upper roller mainly drive, the lower roller for vertical ascending and descending movement, so clamping plate material, through the lower roller gear and the upper roller gear teeth bite, and the main drive bending machine teeth bite. E. The side roller is inclined and ascending and descending, with double functions of pre-bending and rolling ring, compact structure and close relationship, convenient operation and maintenance.
 Meet for the deformation of sheet metal bending can be rolled round, arc and a range of conical workpiece, and has the function of bending of sheet metal ends, this model of the roller under the conditions of the two active roll can move horizontally, the roller is driven roller can move up and down, move way are mechanical and hydraulic, transmission shaft are connected see fit while using the universal shaft coupling.
 When sudden tempering occurs during oxyacetylene welding, the mixture (slow air) switch should be turned off immediately, followed by oxygen and calcium carbide. After cooling, a small amount of the gas mixture is removed to drain the ash from the vent and then re-ignited.
 In order to improve the performance of symmetrical three-roll plate winder, the metal plate can be rolled into round, arc and cone shapes within a certain range. The machine has two lower rollers as driving rollers and upper rollers as driven rollers, which are widely used in shipbuilding, boiler, aviation, water and electricity, chemical industry, metal structure, machinery manufacturing and other industries.
 The main unique and special place of the hydraulic three-roller symmetrical bending machine is: the upper roller can be vertical lifting, hydraulic oil acting on the hydraulic cylinder piston rod vertical drive; The lower roller is driven by rotation, and the white teeth output by the gear of the decelerator are clenched to supply torque for the bent plate; The lower roller is driven by hydraulic oil on the piston rod of the hydraulic cylinder. The lower roller has support roller, adjustable, the upper roller is drum shape, improve the straightness of the product. Suitable for use in various extra-long specifications of section shape tanks.
 The upper work roll is preset for waist drum, that is, the middle diameter is large, then gradually reduced to both ends, so that it can be in a straight situation, but the calculation is difficult.
 Three-roller asymmetric bending machine, the upper roller is the main drive, the lower roller is vertical up and down movement, so that the rolling plate clamping, and through the lower roller gear and the upper roller gear teeth bite, at the same time as the main drive; The side roll has the double function of pre-bending and rolling. Simple structure, convenient operation and maintenance, four roller winding machine roller main drive, through the speed reducer and cross slider coupling and roller connection, for the coil plate supply torque; The lower roller is vertical ascending and descending movement, and r is obtained by the worm gear (bevel gear) of the decelerator, which is delivered by the main screw, and the clamping plate is mechanically driven. The side roller is arranged on both sides of the lower roller through the main screw, and it is tilted along the guide rail of the frame. The screw, worm wheel and worm wheel (or bevel gear) are driven in pairs. The four work rollers feel appropriate and use rolling bearings.
 Check the amount of oil stored in the lubricating oil system should meet the requirements, and close the call center, oil mark, oil window, oil cup, nozzle, oil pipe, oil felt, oil pipe, oil separator, etc., should be intact, accurate installation, manual refueling according to the requirements of the lubricating oil clear table. Check whether the oil flows out of the oil window.
 According to teli winding machine Tldyjc.com reported that the operation of the operation of the winding machine to assume the position of the safe operation technology will also have a very serious and fair standard, so as to ensure that the use of bending machine equipment to work time will not be exposed can not estimate the accident, And without damage to the winding machine under the premise of no difficulties to complete the work process.
 The three - high mill can be divided into mechanical and hydraulic. Machine type can also be divided into symmetrical type and wrong name type, used for heavy machinery companies, metal sheet material processing into a round, arc, the technology has been used in aviation shipbuilding, boiler machinery manufacturing, water, electricity and chemical industries.
 Wish your 2019 smooth sailing, two dragons take off, three Yang Kaitai, spring, summer, autumn, winter, spring, summer, autumn and winter seasons without danger, five blessings, 66 dashun, seven stars shine, southeast, northwest four directions to the money, 99 ideas consistent, perfect and lossless!
 Welding is a sheet metal surgeon. It is a very important major in the mechanical industry. Winding machine parts processing often feel appropriate and the use of welding process, which also determines the quality of the product.
 Secondly, PLC can be used to interrupt the material appearance analysis. When the programmable controller fails, the cause of the side break is remembered as an interrupt stack. The use of hydraulic coiling machine programmer can stop the material appearance of the system, buy four-roller coiling machine, call up the interrupt stack and block stack, according to the reason indicated, four-roller coiling machine quotation, check the existence of the fault. This is a common effective and rapid method in the maintenance of the PLC winding machine.
 Collets, dials and protruding parts of the heart clip holding the workpiece should prevent clothing and body from being hung.
 Plate rolling machine is a kind of common forging machine equipment that can bend and roll nonmetallic sheet into cone, ball surface body, cylinder or other shapes. This performance is widely used in manufacturing, boiler steam, chemical industry, nonmetallic structure and machine manufacturing. The four-roller plate rolling machine is suitable for the bending and forming of metal sheet. It can roll round, arc and conical workpiece within a certain range, and has the pre-bending function of sheet end. The remaining straight edge is small, and the work efficiency is high.
