Mold processing refers to the processing of forming and blanking tools, in addition to shearing dies and die-cutting dies. Usually, the mold consists of two parts, an upper mold and a lower mold. The steel plate is placed between the upper and lower dies, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the die will be obtained or the corresponding scrap will be removed.
Mould processing
1. Grinding of parts
Internal and external grinders, tool grinders and surface grinders are three methods of machine tool grinding. During fine grinding, grinding deformation and grinding cracks should be strictly controlled. Therefore, the fine grinding feed should be small, not large, and the coolant should be sufficient. .
2. Heat treatment of parts
It is necessary to control the internal stress. During the heat treatment of the parts, ensure the dimensional stability of the parts during the processing. With the development of the mold industry in recent years, different materials have different treatment methods, and the types of materials used are also Increase.
3. Surface treatment and assembly
The wear marks and tool marks left on the surface of the part during processing are the source of crack propagation and the place where the stress is concentrated. Therefore, before assembly, the workpiece should be demagnetized, and the surface should be cleaned with ethyl acetate. After processing, the surface of the part should be cleaned Strengthening to eliminate processing hidden dangers, in the process of grinding and electrical machining, the workpiece will have certain magnetization and weak magnetic force, so it is easy to attract some small things.
4. Electrical processing control
Electrical machining cannot be lacking in modern mold factories, which can be divided into two types: wire cutting and EDM. When processing punches, the selection of wire cutting positions and paths should be carefully considered. The best effect is to punch and thread. It can be realized that when machining a concave die with a taper, from a fast and efficient point of view, the straight edge is first roughed, then the second taper machining is performed, and then the straight edge is finished, and only the straight edge of the cutting edge section is finished, which saves money. time and cost savings.
