模具损耗原因
模具损耗原因
Causes of Die Loss
1)模具主要工作零件的材料的问题，选材不当。材料性能不良，不耐磨;模具钢未经精炼，具有大量的冶炼缺陷;凸凹模，锻坯改锻工艺不完善，遗存有热处理隐患。
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)模具结构设计问题，冲模结构不合理。细长凸模没有设计加固装置，出料口不畅出现堆集，卸料力过大使凸模承受交变载荷加剧等。
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)制模工艺不完善，主要表现在凸、凹模锻坯内在质量差，热处理技术及工艺有问题，造成凸、凹模淬不透，有软点及硬度不均。有时产生微裂纹、甚至开裂，研磨抛光不到位，表面粗糙度值过大。
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)无润滑或有润滑但效果不佳、
4) No lubrication or lubrication, but the effect is not good.
