Structural composition of blanking die
- 2019-12-30-

Blanking die, which consists of two parts: upper die and lower die. The upper mold contains the upper template and all components mounted on it, and the lower mold contains the lower template and all components mounted on it. When the die is installed on the press, the die handle of the upper die is clamped in the die handle hole of the slider of the press, moves up and down together with the slider, and is fixed on the work surface of the press by screws and pressure plates. Its operating principle is as follows. Before the die is punched, the strip is fed against the two guide pins until it touches the guide pin on one side. When punching, the discharge plate first presses the data, then the punch is punched, and the punched workpiece leaks from the hole of the die. When the upper mold is raised, the waste material is unloaded from the punch by the elastic force of the compression rubber. The second and subsequent feedings are positioned by the stopper pins and punched at one orientation. After punching the bar, turn it 180 degrees, and then punch the dotted line in the layout chart. The die structure consists of the following.

Structure drawing of blanking die

①Working parts

The part that separates the data for the completion of the punch, including the punch and the punch.

② Positioning parts

It is the part that confirms the correct orientation of the strip in the die. The guide pin plays a guiding role in the feeding of the data. When the strip deviates from the guide pin, it will flush out the missing scrap. The blocking pin restricts the orientation of the strip feed. Cross-cutting, after one punch, leave an orientation to flip the strip 180 degrees and punch back, so the distance from the stopper pin to the edge of the die hole is one workpiece width plus two overlapping edges, so that the strip is punched and positioned after the flip .

Zhejiang Renxin Mould Technology Co., Ltd. has maintained rapid development since the establishment of Taizhou Luqiao Renxin Company in 2003, and its business scope has expanded rapidly.
