Problems solved by technology

Therefore, the production process of the mold can be divided into five main stages: preparation of production technology, preparation of materials, processing of mold parts and components, assembly debugging and trial appraisal. There are certain defects in the existing stamping mold manufacturing process. The service life of the mold is not high, the hardness is not high enough, and it is easy to be damaged if it is used for a long time

Abstract

The invention discloses a production process for a stamping die. According to the production process disclosed by the invention, molten metal is cast at a low speed or a high speed and the cavity of the die is filled with the molten metal at first in a die die-casting process. The die adopting high-speed steel is quite high in hardness, wear resistance, compressive strength and bearing capacity; moreover, the hardness of the die is enhanced through quenching and three-time tempering treatment; the prepared die is high in mechanical performance, so that the service life of the die is greatly prolonged; manufacturing for the die has the advantages of being reasonable in design, simple to operate, safe and practical, and the like; and the die can be generally popularized and used.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing technology, in particular to a stamping die production technology. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a kind of mechanical equipment. The production process of a machine refers to the entire process of making products from raw materials. For machine production, it includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly, and debugging, painting and packaging. The content of the production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize and guide production, and regard the production process as a production system with inputs and outputs. [0003] With the development of China's economy, the mechanical processing industry has developed rapidly. ...
