Problems solved by technology

[0002] In the cold stamping process, the punch of the processing equipment plays a key role. The punch in the prior art has hardness but poor toughness or poor toughness but insufficient hardness, and is often easily deformed and not resistant to impact or resistance. Grinding, as the requirements for processing parts increase, the disadvantages of this processing head become more and more obvious

Abstract

The invention discloses steel for manufacturing a punching head of punching machining equipment. The steel is characterized by comprising the following components of, by weight, 1-1.5 wt% of C, 0.4-0.5 wt% of Mn, 10-15 wt% of Cr, 0.5-1.5 wt% of Mo, 0.3-0.4 wt% of V, 0.5-1 wt% of Si, 0.6-0.9wt% of Ni, and the balance Fe and impurities. Compared with the prior art, the steel for manufacturing the punching head of the punching machining equipment is hard steel which has the characteristics of extremely high hardness, proper toughness, temper hardening effect, wear resistance, non-deformation, impact resistance and the like, so that the service life of the punching head is greatly prolonged.

Description

technical field [0001] The invention relates to a steel for manufacturing punches of stamping processing equipment, and belongs to the technical field of iron and steel materials. Background technique [0002] In the cold stamping process, the punch of the processing equipment plays a key role. The punch in the prior art has hardness but poor toughness or poor toughness but insufficient hardness, and is often easily deformed and not resistant to impact or resistance. Grinding, as the requirements for processing parts increase, the disadvantages of this processing head become more and more obvious. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a steel for manufacturing punches of stamping processing equipment. [0004] In order to solve the above technical problems, the present invention provides a steel for manufacturing stamping equipment punches, which is characteriz...
