What failures often occur in the Sheet Metal Fabrication process?

Sheet Metal Fabrication often fails during use. Without the guidance of professionals, it is difficult for us to accurately determine the source of the failure of the laser cutting equipment. We can only explore it based on our own experience, but if some failures occur, we will Some are at a loss, so the following Metal Stamping Manufacturer will explain to you:

First, the chiller is easy to alarm in summer, which affects the efficiency of precision sheet metal processing.

This problem is usually the weather is too hot, the chiller does not heat well or the cooling capacity is not enough, the self-cooled water chiller will not have the problem of insufficient cooling capacity, generally, the heat sink is too dirty, and the ventilation part is good, which will cause an alarm. A small chiller is generally insufficient in cooling capacity. You can increase the temperature difference and raise the alarm temperature appropriately to solve the problem.

Sheet Metal Bending

Second, the end face of the product is bulging or uneven.

Cause: When Sheet Metal Bending is applied, the outer the surface of the material is stretched in the circumferential direction to cause contraction and deformation, and the inner surface is compressed in the circumferential direction to cause elongation and deformation, so that the flexed end surface in the bending direction produces bulging.

Third, the bending size of sheet metal processing is small, it is difficult to locate, and the upper mold is easy to press on the back gauge; the reason: because t = 0.8, the principle of pressing the mold is selected, v = 5 × 0.8 = 4mm. The distance between the sides is 3.5mm, and the inner dimension of 2.9mm is 2.9-0.8 = 2.1mm. The bending dimension is within the distance from the v centerline to the side, and it cannot be positioned when it is installed. When the lower mold is reversely installed, the upper mold will hold it. Post-regulation, front and back loading will not work, think of other methods; Solution: ○ 1 can be reverse-loaded. Add a gasket before the post-regulation (not greater than 3t), so that the post-regulation moves backward and avoids Mould ○ 2 If the size of the other end is ≧ 3, the other end can also be used.

Fourth, the sheet metal processing feedback to the laser or NCT, let it pay attention to the selection of materials, change the mold, adjust the middle block.

Problem: During the bending of sheet metal, some workpieces will be deformed. Reason: This happens mainly because the C position is the post-determined position. When the B position is bent, the workpiece bends and moves up and hits the rear. On the rule, it is squeezed by the back rule. After bending and forming, the D position is squeezed and deformed. The solution: use the back rule and pull function.

Fifth, the sheet metal processing cannot be started and it trips when the room is open.

Whether the emergency stop pops up, whether the external circuit is connected, whether the internal open circuit of the device is closed, whether you hear a pop sound when you turn on the machine, if any, please check the main contactor and control transformer, etc .; water leakage caused the laser power supply to short circuit , The pump is short-circuited, the indoor open circuit is too small and so on.
