Detailed introduction

Die wear reasons:

1) The material selection of the main working parts of the die is inappropriate. Material performance is not good, wear-resistant; die steel is not refined, with a large number of smelting defects; convex and concave die, forging process is not perfect, there are hidden dangers of heat treatment.

2) The design of die structure is unreasonable. The slender punch has not designed reinforcing device, the discharge outlet is not smooth, and the unloading force is too strong to make the punch bear the increasing alternating load and so on.

3) Imperfect die-making process is mainly manifested in the poor internal quality of forged blanks of convex and concave dies, the problems of heat treatment technology and process, resulting in the hardenability of convex and concave dies, and the uneven softness and hardness. Sometimes micro-cracks, even cracks, lapping and polishing are not in place, and the surface roughness value is too large.

4) No lubrication or lubrication, but the effect is not good.
