Cold bending machine commissioning manual, cold bending machine commissioning method

The debugging of cold roll forming machine requires a certain work experience. In the work, we must summarize slowly, and we must use our brains to debug the equipment. Especially when debugging equipment with complex cross-section products, we need a long-term experience summary. It is very important to debug the cold-form forming machine. If you have a calm response, do not be irritable, and use your brain, it is possible to train an excellent cold-form forming machine commissioning master. In order to make it easier for you to master the debugging methods of cold-formed machines, we have prepared the following manuals for your reference. They introduce some methods of debugging cold-formed machines that are often encountered in daily work. The following methods are suitable for roll design. Reasonable, because debugging took a long time, or unfamiliar reasons, debugging was messed up, and re-commissioning returned normally. However, some rolls need to be modified because the roll design is unreasonable when leaving the factory. The roll design is unreasonable and it is difficult to debug. Therefore, if it is a roll problem, the manufacturer should be contacted to modify the roll.

In the daily use of cold roll forming machines, the common problems encountered are: distortion, wavy edges, longitudinal bending, etc. Such a problem is generally caused by uneven force at the points of force of the rolls, and the rolls are deviated from the left and right in a straight line. Therefore, when debugging the cold bending machine, we must grasp a central point to consider the problem, that is, the roll must To be on a straight line, the upper and lower gaps of each set of rolls should be the same. Therefore, when a problem occurs in the cold roll forming machine, it should be debugged around this central idea. So, in what way can the roll midpoint be on a straight line, and how can the gap between the upper and lower rolls be guaranteed to be the same? The following methods will answer your questions.

First, the method of keeping all the rolls in a straight line. First determine the center points of the first group and the last group. The center points of the two sets of rolls are moved to the center from left to right. Then draw a straight line based on these two points. Mark the center point. After painting with chalk, use the center caliper to mark the center point. Mark all the center points in the same way for all the rolls on the machine, and then adjust the center points of the rolls on the straight line. After straightening the lower roll, install the upper roll back.
Second, the method of debugging the gap between the upper and lower rolls . We should prepare a small section of raw materials for production, the thickness is the same as the usual materials, and then cooperate with a small mirror and a flashlight. Put the material between the upper and lower rolls, and then tighten the screws on the left and right sides uniformly at the same time. Be careful not to tighten one side first and then the other side. This may cause the gap between the two sides to be inconsistent. After tightening, use a mirror to illuminate on one side to see if the gap inside just fits, while using a flashlight on the other side, if the gap is uneven, the light transmission will be uneven. After confirming that the gap is uniform, loosen it a little, it is better to take out the material you just put in. At this time, tighten the left and right screws. Try adjusting all the gaps in turn in the same way.

After mastering the above core methods, you need to be flexible and use different methods for different problems. When there are some problems sometimes, we can't pull the straight line again every time as above, it will be time-consuming and labor-intensive. When a minor problem occurs, we can check the materials one by one, so we can know From which group has a problem, when the material head first enters the roll, we can roughly see which group is not on a straight line. Or use the method to check the gaps in groups. When distortion or edge waves occur, it may be that one or more groups of left and right pressures are inconsistent or not on a straight line. When longitudinal bending occurs, some groups may be too tight. Everyone can use different debugging methods to solve according to different situations, and slowly conclude that after a period of time, you will be handy.
