Description

The present invention is related to the mold field, and specifically, is a punching die equipment capable of suppressing deformation of a processed product.

Punching is a pressing process that uses a die to separate some materials or processes from other parts, processed or useless materials, and punching is shearing, material removal, drilling, grooving. , A general term for separation processes such as cutting, cutting, edge cutting, tongue cutting, and tearing. In the punching process, plastic deformation occurs in the plate material itself of the processed product, except for shearing the metal near the contour line. Therefore, the shape of the flat plate punching part is still flat, and the plate material of some processed products needs to be punched at the edge. When the punching method is used, the plate material of the processed product becomes severely deformed and cannot meet the production requirements, and when the cross section of the die changes, it is generally punched by deploying a die corresponding to the cross section. The punching die equipment that can complete the processing, increase the production cost, and suppress the deformation of the processed product described in the present invention can solve the above problems. Since the horizontal state can be maintained, machining errors are reduced, the machined product after punching avoids deformation, and the cross section of the shear contour of the machined product is completely determined by the cross section of the die. There is no need to deploy compatible dies, and production costs can be reduced.

Slides downward to compress the cushioning spring 44, the cushioning plate 45 does not slide, the shaft sleeve 54 rotates, the die 24 is driven by the lead screw 42, and slides downward from contact with the cushioning plate 45. The cushion plate 45 is pushed and moved by the elastic force of the buffer spring 44 to slide out of the position limiting groove 45, and at the same time, the die 24 slides downward to punch out the work piece 25. The support rod 27 facing the die 24 is slid downward, and the other support rod 27 continues to support the processed product 25. At this time, the pressure in the sealed space 28 and the buffer space 15 is increased, and the air pump 16 is started. Then, the pressure inside the buffer space 15 and the sealed space 28 is sucked up, and the buffer space 15 and the sealed space 28 are sucked up. A constant value is maintained at the air pressure in 28, and at this time, the support rod 27 that slides downward assists the die 24 to punch out the processed product 25, and the lower end of the die 24 is below the sandwiching space 21. When the side inner wall is exceeded, the electric motor 59 is stopped, and the punching process of the processed product 25 is completed here.

When the electric motor 59 is started to rotate in the opposite direction, the die 24 is raised to separate it from the processed product 25, and the upper end of the die 24 comes into contact with the cushioning plate 45, the cushioning plate 45, the link 48, and the slide plate are used. The 48 and 48 are raised, and the shaft sleeve 54 is disconnected from the lead screw 42, and the die 24 is no longer raised. At this time, the cushioning plate 45 is housed in the position limiting groove 46, and the electromagnetic spring 39 loses power. Then, the slide gear 40 is connected to the small pulley 56 and the screw 30 again, and the sandwich plate 22 is driven to rise and separate from the processed product 25. At this time, the processed product 25 and the processed product 25 after punching are sheared. The falling material is taken out, and the air pump 16 injects gas into the buffer space 15 and the sealed space 28, so that the support rod 27 returns to the initial state.

The effect of the present invention is: The present invention sandwiches the processed product and keeps the processed product in a horizontal state at the time of processing, reduces the processing error, avoids the problem that the processed product is deformed after punching, and also The cross section of the shear contour of the processed product is completely determined by the cross section of the die, so no corresponding die is required and the production cost can be suppressed.

According to the above method, those skilled in the art can make various modifications according to the working situation within the scope of the present invention.
