随着CA141型汽车产量的增加和质量要求的提高,热锻模的使用与供应已经成为汽车生产中的一个重要环节,并直接关系着成本的高低及质量的好坏。一台CA141型汽车有93种锻件(总质量约505公斤),其费用为汽车成本的1/16,而模具费用约占锻件费用的1/6。这说明提高横具寿命,降低模具消耗是多么重要。由于锻件飞边厚度的限制,小件轴类模具常常达不到寿命要求。例如前刹车蹄片轴模具的寿命定额为1.5万件,而实际只能达
With the increase of CA141 automobile production and the improvement of quality requirements, the use and supply of hot forging die has become an important link in the production of automobiles and has a direct bearing on the level of cost and quality. A CA141 car has 93 forgings (a total mass of about 505 kilograms), which costs 1/16 of the cost of a car, while mold costs account for about a sixth of the cost of forgings. This shows how to improve the transverse life, reduce mold consumption is how important. Due to the thickness of the forging flash edge, small pieces of mold often do not meet the life-span requirements. For example, the service life of a front brake shoe mold is 15,000 pieces, which can only be achieved in practice
