Release time:2014-08-20 09:13:52 Source of the article:qyjljc Number of clicks:1865

  When processing the workpiece by the coiling machine, pay attention to the following items:

  First, if the coiler is found to have abnormal noise, shock, vibration, leakage, hydraulic oil, motor, and bearing temperature is too high, it should immediately stop the inspection and make corresponding treatment.

  2. When testing the roundness with the sample, it must be done after the winding machine stops.

  3. It is strictly forbidden to take the lead when the steel plate is rolled, and overload is strictly prohibited. The personnel who operate the coiling machine must stand on both sides of the rolled steel plate. The coiling machine (the effective working surface of the upper roller) must not stand before or after the coiling machine. When rolling, the plate must not stand to prevent the rolled workpiece from protruding or falling. Injury occurred.

  4. The specifications of the rolled sheet shall not exceed the scope of the equipment instructions. The pressure of the upper roller shall not be adjusted arbitrarily. The operator must observe the operation.

  5. The rolled workpiece must be placed in the center of the roller for rolling, and no slippage is allowed during the rolling process.

  6. During the process of steel coil and pressing, the operator must observe the operation of the sheet at all times. The sheet shall not be stripped. When the length reaches the end, when the symmetrical roll is made into a profile beyond the radius, the opening of the work site is not allowed to enter.
