Installing and Commissioning Roll Forming Machine

Before the installation of the rollers, each group of radial run out and axial run out of the lower shaft should be tested to ensure that the amount of 0.02mm. After installation, the lower shaft shall be guaranteed to rotate uniformly, easily and flexibly. Determine a straight line based on the shoulder spacer of the first and last two shafts of the lower shaft, and correct all the spacer sections in the same straight line as shown in Figure 1.

1. For the installation of the rollers, we recommend the wire-drawing method. The purpose is to make the square line of the rollers in a straight line. Adjustment of the final purpose to ensure that the upper and lower roller and the left and right side of the wheel level and vertical position corresponding to the adjustment shown in Figure 2.

2. After installing the lower and upper wheels according to the assembly requirements, lock the four screws on its plaque. Wait for the whole machine to pull out the sample after test run. After confirming that the precision of its sample meets the technical requirements of customers or drawings, lock all the screws on the side plaques on the equipment.

3. According to the conditions of assembly requirements, corresponding to the nut of the upper wheel to drive the upper and lower wheel clearance or left and right side wheel clearance (clearance equal to or slightly less than the thickness of the material). Through the standard plug ruler to detect its gap as a benchmark, and ultimately after the trial machine to assess the accuracy of the sample accuracy of the gap is accurate.

4. Adjust the height of the last straightening upper wheel and straightening lower wheel according to the deformation and other defects of the sample of the test machine to correct the bending of the material. If the material is warped, lower the height of the last straightening upper wheel and straightening lower wheel at the same time. If the material bends down, raise the height of the last straightening upper wheel and straightening lower wheel. In the case of small bending, directly adjust the straightening upper wheel or lower wheel, it is not necessary to ad just at the same time.

Note: Straighten the upper and lower wheels can not be pressed too tightly, too tightly convergence leads to the overall width of the product size changes.
