我厂有一工件如图1所示,管外径为φ51,来料长78mm,壁厚1.5mm,要求一破为二,斜度≈16°30′,我们设计了一套切管冲模,如图2所示。它主要特点是,除切刀上下运动外,还有为卡紧管子的水平运动。为保证两种运动协调,要求刀架等零件须在导轨内滑动自如,所以,模具制造比较精密,要求较高。 I have a workpiece factory as shown in Figure 1, the tube diameter φ51, incoming material length 78mm, wall thickness 1.5mm, requiring a broken second, the slope ≈ 16 ° 30 ’, we designed a set of cutting die, such as Figure 2 shows. Its main feature is, in addition to the cutter up and down movement, there is horizontal movement for clamping the pipe. In order to ensure the coordination of the two kinds of sports, parts such as the tool holder must be slid freely within the guide rail. Therefore, the manufacturing of the mold is more precise and requires higher.
