在用模具生产的冲压件中,其平均厚度大都在2～4mm。从经验及资料中知道,在这一范围内的凹凸模单边间隙为0.1—0.2mm,而采用线切割加工时,钼丝直径一般为0.1～0.15mm。如果利用线切割加工中钼丝工作的切缝来代替冲裁模中凹凸模的相配间隙,则能收到事半功倍的效果。现举例说明如下: 图1所示是电器箱上一只要加工的锁孔的形状,冲裁模结构见图2。现要在一块坯料(图3)上一次获 In the stamping parts produced by the mold, the average thickness of mostly 2 ~ 4mm. From experience and information to know that in this range of punch and die clearance of 0.1-0.2mm, and the use of wire cutting, molybdenum wire diameter is generally 0.1 ~ 0.15mm. If the use of wire cutting molybdenum wire work in place of the kerf die punch punch to match the gap, you can receive a multiplier effect. An example is as follows: Figure 1 shows the electrical box on the shape of a keyhole to be machined, stamping die structure shown in Figure 2. Now in a blank (Figure 3) on the last
