The debugging of the cold-formed forming machine requires a certain degree of work experience. Slowly summarize in the work and use more brains to debug the equipment.
Especially when the equipment is debugged with complex cross-section products, it is necessary to have a long-term experience summary. If you want to debug the cold roll forming machine well, it is very important to deal with it calmly, not irritable, and use your brain to train and become an excellent cold roll forming machine debugger.
In order to make it easier for everyone to master the debugging methods of the cold roll forming machine, we have specially compiled the following manual for your reference, introducing some of the debugging methods of the cold forming machine that are often encountered in daily work.
The following method is suitable for the reasonable design of the roll, because the time is used for a long time, or the adjustment is messy for unfamiliar reasons, and the adjustment is normal. However, some rolls need to be modified because of the unreasonable roll design at the factory. Unreasonable roll design is difficult to debug. Therefore, if it is a roll problem, you should contact the manufacturer to modify the roll.
In the daily use of cold roll forming machines, the usual problems encountered are: twisting, edge waves, longitudinal bending, etc. This kind of problem is generally caused by the uneven force on the various points of the roll, and the roll is not in straight line when it runs off from the left and right. Therefore, when we debug the cold bending machine, we must grasp a central point to consider the problem, that is, the roll must be to be in straight line, the upper and lower gaps of each set of rolls should be the same. Therefore, when there is a problem with the cold roll forming machine, it should be debugged around this central idea.
Then, what method can be used to make the midpoint of the rolls be in a straight line, and how can the gap between the upper and lower rolls be the same? The following methods will answer for you.
1. The method of the keeping all the rolls in a straight line.
First determine the center points of the first group and the last group, and move the center points of the two groups of rolls to the center from left to right. Then draw a straight line based on these two points. The draw a straight line based on two points. The center point mark can be pained with chalk, and then use the center caliper to mark the center point. All the lower rolls on the machine are marked with the same method, and then the center points of the rolls are adjusted to the straight line. After the lower roll is straightened, install it back to the upper roll.
2. The methods of adjusting the gaps between the upper and lower rolls.
We should prepare a small piece of raw materials for production, the thickness of which is the same as the usual materials, and a small mirror and a flashlight. Put the material between the upper and lower rollers, and then tighten the screws on the lower rollers, and then tighten the screws on the left and right sides evenly at the same time.
Be careful not to tighten one side and then the other side, as this will cause the gap between the two sides to be inconsistent. After tightening, use a mirror to look at one side to see if the gap inside just fits, and at the same time use a flashlight on the other side. If the gap is not uniform, the light transmission will be uneven. After confirming that the gap is even, loosen it slightly to be able to take out the material just put in. At this time, tighten the left and right screws. Try to adjust all the gaps in the same way in turn.
After mastering the above core methods, you must be flexible and use different methods for different problems. When there are some problems sometimes, it is impossible for us to re-draw the straight line according to the above method every time, it will be very time consuming and laborious. When there is a minor problem, we can pass the inspection one by one.
In this way, we can know from which group the problem occurred. From the moment the material head just enters the roll, we can roughly see which group is not in a straight line. Or directly use the method to check the gap in groups. When there is distortion or edge waves, it may be that the left and right pressures of a certain group or several groups are inconsistent or are not in a straight line.
When there is longitudinal bending, it may be that the pressure of certain groups is too tight
You can use different debugging methods to solve them according to different situations. Summarize it slowly. After a period of time, you will be handy.
