为制作图1所示工件,我设计了一套自动压管模(图2)。该模具由四部分组成:1.送料机构(图略);2.下料—压弯机构;3.送件机构;4.压圆机构模具的工作过程:当带料送入靠近定位板5的一瞬间。下料刀4和凹模9、凸模3及凹模8同时进行切料和u型压弯,此时,送料杆6已退出,当滑块开始回升时,它再将工件传递给压圆模滑块第一次下降时,压圆模是空程,而第二次下降时,压块22下压压圆模23、25,即把U型工件压成管子,当滑块回升
To create the workpiece shown in Figure 1, I designed an automatic die (Figure 2). The mold is composed of four parts: 1. feeding mechanism (omitted); 2. blanking-bending mechanism; 3. feeding mechanism; 4. working process of the die pressing mechanism: when the strip is fed close to the positioning plate 5 The moment. Blanking knife 4 and die 9, punch 3 and die 8 at the same time cutting and u-bending, at this time, the feed rod 6 has been withdrawn, when the slider starts to pick up, it will then pass the workpiece to the round pressure When the mold slide is lowered for the first time, the pressure round mold is empty, and the second fall, the compact 22 presses the round mold 23, 25, that is, the U-shaped workpiece is pressed into a tube,
