散热片是我厂主要产品NB140高压柱塞泥浆泵液压站主要冲压件之一。其几何形状如图1所示,原材料为1 mm厚的T_2紫铜。工艺过程是:下条料—上连续模(图2)冲压,按排样图跳四步完成制件:第一步冲孔;第二步翻边;第三步校平;第四步切断。而且操作安全可靠,模具寿命长,产品质量较好。模具的主要特点有: 1.选用固定挡料板、两个始用挡料销定距。 2.为了保证冲头25在冲制过程中稳定,装有护套14,它同
Heatsink is the main product of our factory NB140 high pressure piston pump hydraulic station one of the main stamping parts. The geometry shown in Figure 1, the raw material is 1 mm thick T_2 copper. The process is: under the strip material - on the continuous mode (Figure 2) stamping, according to the layout of the map jump four steps to complete parts: the first step punching; the second step flanging; the third step leveling; the fourth step off . And safe and reliable operation, long mold life, product quality is better. The main features of the mold are: 1. Selection of fixed retaining plate, the two start with the expected pitch pin. 2. In order to ensure that the punch 25 is stable during the stamping process, a sheath 14 is provided, which is the same
