The roll plate bending machine is a kind of equipment that bends and forms sheet materials via work rolls. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. Due to the different fields of use, the types of plate bending machines are also different. According to the number of rolls, it is divided into three-roller and four-roller. 3 roll plate bending machine has mechanical and hydraulic type: mechanical three-roll plate bending machine is divided into symmetrical and asymmetrical. Sheet metal can be rolled into circular, arc and conical workpieces within a certain range.
When the 3 roll plate bending machine is started, it is necessary to make preparations to ensure that it can run normally when it is used, and there are some details that need our attention when it is started.
1. First of all, it is necessary to check whether there is any abnormal situation in each part of the 3 roll plate bending machine. If any abnormal situation is found, some screws need to be tightened to ensure that there will be no looseness. Only in this way can the brake be normal and reliable.
2. It is necessary to adjust the distance of the reel strictly according to the thickness of the plate to ensure that the plate bending machine will not be overloaded during operation.
3. When the 3 roll plate bending machine is in operation, it is still not allowed to roll and press workpieces that have exceeded the mechanical performance regulations.
Be sure to make sure that the workpiece has been placed stably, wait until the position is correct before you can drive the car for operation, and you need to make it clear that the signal will be commanded by one person.
4. When rolling some workpieces that cannot be rounded, it is generally recommended to reserve a certain margin as much as possible when rolling to the end of the steel plate, so as to ensure that the workpiece will not drop suddenly during processing.
5. When rolling a steel plate with a relatively large thickness, the ratio between the radius of the finished product that is rolled and the radius of the finished product that needs to be rolled should be less than 2, and then it needs to be used after rolling 2 to 3 times. relatively small diameter.
The above are the precautions when the 3 roll plate bending machine equipment is started. When starting, it is necessary to check whether the oil in the oil storage tank is sufficient. Only in this way can it be ensured that it is in a normal state during operation.
