The development of heavy industry in modern society is getting faster and faster, and the birth of aluminum alloys has promoted the development of many industries. Aluminum alloy shell products are now ubiquitous in daily life. Stamping is a relatively basic and common method in the processing of aluminum alloy shells. The combination of stamping and CNC machining can obtain aluminum shells for various products, while some products only require or exceed pure stamping.
The determination of the number of processes is crucial for complex aluminum shells that require pure stamping. The number of processes has a certain impact on product dimensional accuracy, production efficiency, production costs, etc. What issues should be considered when determining the number of stamping programs
(1) Order quantity for aluminum alloy shells: In large order production, each process should be combined as much as possible, using composite stamping or skip stamping to improve production efficiency and minimize production costs. In the production of small and medium-sized orders, simple mold stamping can be used to reduce mold manufacturing costs.
(2) Dimensional accuracy requirements for aluminum shells; When the dimensional accuracy is high, some auxiliary processes can be added appropriately to ensure product accuracy and reduce waste.
(3) The existing forming conditions and stamping equipment of the enterprise; The overly complex mold manufacturing and assembly pose a huge challenge to the standards of enterprise mold manufacturing conditions.
(4) Stability of aluminum shell mold production; There are many factors that affect the stability of molds, such as mold materials, mold assembly accuracy, lubrication conditions, etc. When determining the number of processes, it is possible to increase some processes appropriately to avoid extreme deformation during the stamping process, thereby effectively improving the stability of the stamping process.
