针对单击冷镦机的缺点,该厂与齐齐哈尔第二机床厂共同设计和制造了Z31—8、Z31—12、Z31—16三种规格的双击自动冷镦机。 文中简述了机床的传动,工作循环,机床的工作过程。 Z31—8每分钟冷镦滚子105个,Z31—12每分钟冷缴滚子80个,Z31—16每分钟冷镦滚子65个。 文中对单击和双击冷镦机作了比较。双击冷镦机的优点是: 1.滚子小头外径无欠冲现象。 2.精冲后的滚子环带小而端正,冲成后可直接淬火。 3.模具寿命提高。 4.双击冷镦时,滚子棒料尺寸选用范围大,不存在因料小而产生掉料。 附图5幅。
For the shortcoming of clicking the cold heading machine, this factory and Qiqihar No.2 machine tool factory jointly design and manufacture the double-click automatic cold heading machine with three specifications of Z31-8, Z31-12 and Z31-16. The paper briefly describes the transmission of the machine tool, working cycle, the working process of the machine tool. Z31-8 cold forging roller 105 per minute, cold-rolled Z31-12 per minute 80, Z31-16 per minute cold heading roller 65. The paper compares single-click and double-click cold heading machines. Double-headed cold heading machine has the following advantages: 1. The outer diameter of the roller head has no undercut phenomenon. 2. Fine blanking roller ring with small and straight, red quenched directly after. 3 die life increase. 4. Double-click cold heading, the selection of roller bar size range, there is no small material due to the expected material. Figure 5 Figure.
