Where to dongguan sheet metal processing need to pay attention

With the rapid development of economy, sheet metal processing industry has been applied more and more widely in various industries. Today Xiaobian is mainly to tell you briefly what Dongguan sheet metal processing needs to pay attention to.
1, material quality, we must carefully check, thickness and thickness tolerance.
2. For special angles, the inner radius of the bending angle should be tested first before deciding whether to expand or not.
3, make mistakes where you want to make mistakes.
4, in the process of sheet metal processing, the tolerance dimension should be taken into consideration: the minus difference goes to the end, the positive deviation is half, and the hole size is opposite to the tolerance dimension.
5, pay attention to the direction of burr;
6, draw teeth, press riveting, tear, bump, etc. position direction, draw a sectional view;
7, large size should be enlarged to avoid mistakes.
8, the place where the spray protection needs to be made is to be marked.
9, the way to develop sheet metal should be reasonable, not only to save materials but also to ensure machinability.
10, reasonable choice of clearance and edge way, T below 2 clearance is 0.2, the gap between T 2-3 is 0.5.
