| 近几年模具行业快速发展,但是模具制造企业中有相当一部分为民营企业,受资金、场地、技术、信息交流等许多因素的局限.护坡模具制品是国内模具制作业所占比例在不断扩大,护坡模具是现在水利护坡工程中常用的水泥制品模具,以往护坡类型的模具的出产量和出口量远远达不到其它国家的产量,而现在通过技术含量的不断提高,这样的模具的应用日渐广泛,这些对于河北护坡模具厂来说都不是什么问题.护坡模具在塑料模具制品行业所占比例逐步增大,因此,在未来护坡模具加工制作设计行业当中应以技术提高为主要发展目标.护坡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.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,出料口不畅现堆集,卸料力过大使凸模承受交变载荷加剧等.模具制模工艺不完善,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. In recent years, the mould industry has developed rapidly, but a considerable part of the mould manufacturing enterprises are private enterprises, which are limited by many factors such as capital, site, technology and information exchange. The proportion of slope protection mould products in the domestic mould manufacturing industry is constantly expanding. The slope protection mould is now commonly used in the hydraulic slope protection project. In the past, the output and export volume of slope protection molds were far less than that of other countries. Now, with the continuous improvement of technology content, the application of such molds is becoming more and more extensive. These are no problems for Hebei slope protection mold factory. The proportion of slope protection molds in plastic mold products industry is gradually increasing. Therefore, in the future slope protection die manufacturing and design industry, technology improvement should be taken as the main development goal. Material selection of main working parts of slope protection die is inappropriate. Material performance is poor and wear-resistant; die steel is not refined and has a large number of smelting defects; convex and concave die, forging process is imperfect, leaving behind heat treatment hidden. There are structural design problems and unreasonable die structure. Slender punch has no design reinforcement device, the outlet is not easy to stack, the discharge force is too strong to make the punch bear alternating load, etc. The die-making process is not perfect, mainly manifested in the poor quality of the forged blanks of the punch and concave dies, heat treatment technology and process problems, resulting in the hardenability of the punch and concave dies. There are soft spots and uneven hardness. Sometimes micro-cracks, even cracks, lapping and polishing are not in place, and the surface roughness value is too large. |
