In recent years, with the rapid development of the national economy and the intensification of market competition, people have increasingly recognized the importance of stamping quality, cost, and development capabilities. The quality of stamped parts has become an important indicator of the manufacturing level of a hardware processing enterprise. Taking aluminum alloy shell stamping parts as an example, burrs have always been an important factor affecting product quality.
Generally speaking, it is difficult to avoid varying degrees of burrs when stamping aluminum alloy shells. However, identifying the cause of burrs and improving the manufacturability and stamping conditions of the parts can reduce burrs.
The main reasons for burrs are as follows:
(1) Gap: If the gap between the aluminum alloy shell stamping die is too large, too small, or uneven, burrs will be generated;
(2) Blunt blade: When the blade of the aluminum alloy shell mold becomes dull due to wear, or when the blade jumps or cracks, it will produce burrs.
(3) Improper stamping status; Poor contact between the concave and convex molds of aluminum alloy shell molds can result in burrs.
(4) The aluminum alloy shell mold structure is unreasonable;
(5) The material does not meet the process requirements: Inconsistent thickness or hardness of the aluminum alloy shell material can result in burrs;
The problem of stamping burrs has a serious impact on the stamping quality of aluminum alloy shells, and at the same time causes single piece accuracy errors, leading to poor welding assembly. Therefore, solving the problem of burrs is urgent.
