Cold rolled ribbed steel bar production line
Cold rolled ribbed steel bar equipment is a unit used to process ribbed steel bars. It cold-rolls the hot-rolled round wire rod into a steel bar with crescent-shaped cross ribs on three sides after cold-rolling and reducing the diameter. These units usually meet the quality standards of the Ministry of Construction of China.
Cold rolled ribbed steel bar production line equipment maintenance and maintenance
(1) Before starting the machine, you should first check the electrical system, whether the three-phase power supply is connected, whether the voltage is normal, whether the buttons are flexible, and if everything is normal, you can prepare to start.
(2) Check whether the oil level of the mechanical box oil pool is in place, whether the bearings and lubricating parts are well lubricated, whether the rotating parts are flexible, and whether the parent material roundness meets the national standards. - After the cutting is qualified, prepare to start production.
(3) Place the parent material on the pay-off stand and do not mess up the wire. The pay-off stand should be at least 6~14m away from the rust remover. According to the process route, insert the parent material into each machine in turn, perform various operations according to the debugging method and steps, and start production.
(4) During production, it is important to avoid insufficient wire supply from the front machine to the rear machine, which may cause wire breakage. At the beginning of the trial rolling, the wire diameter should be continuously measured to meet the process requirements.
(5) When using the stress relief machine, adjustments should be made based on the test results. Excessive pressure will cause the strength of the steel bar to decrease.
(6) The wire diameter adjustment screw on the wire arranging device should be adjusted according to the different specifications of the product to avoid the phenomenon of tangled wires. When processing large-diameter steel bars, the wire take-up machine is subjected to force because the friction of the finished wire drum is small, which is easy to cause the phenomenon of lost rotation. The number of windings should be increased in time to solve the problem. Large,
(7) When stopping the machine, stop the wire take-up machine first, then stop the pull-up machine. Only after the entire line is stopped can the top of the wire take-up machine be loosened, the empty space of the wire reel can be removed, the safety door can be opened, the lever can be driven, the wire reel can be pulled out, and the bundling can be carried out. Then remove the end cover and use a special hoist to lift the finished product out.
(8) The product should be raised by 200~300mm with sleepers and stored in the warehouse to prevent rust.
