我厂在中小型的锻件上,普遍采用了胎型锻造。在我们生产敝车的53种锻件中,用胎型锻造的占96.5%,平车的51种锻件中,胎型锻造占97.7%。目前已经取得了一定的效果。胎型锻造的优点胎型锻造较自由锻造有很多优点:1.简化工序、操作便利、减少量验的次数,因此可以大大地提高工作效率;2.提高锻件质量,使锻件内部组织细密,外部尺寸一样,有较高的互换性;3.降低产品成本,节约金属、减少机械加工工时; I plant in small and medium-sized forgings, the general use of the tire forging. Among the 53 kinds of forgings we produced for our cars, 96.5% were forged by the tire type and 97.7% for the 51 kinds of flat forging vehicles. Has achieved some results. The advantages of tire forging More free forging tire forging has many advantages: 1. Simplify the process, easy operation, reducing the number of tests, it can greatly improve work efficiency; 2. To improve the quality of forgings, forging the internal organization of fine, external The same size, a higher interchangeability; 3. Reduce product costs, save the metal, reducing machining time;
