Technical Field
The invention relates to the technical field of dies, in particular to a bending die for a washing machine control seat.
Background
The drum washing machine originates from Europe, and the washing method is designed by simulating the principle that a hammer strikes clothes. The control seat is one of the important components of the drum washing machine, and the control seat of the drum washing machine needs to be bent during production. As shown in fig. 1, a schematic structural diagram of a drum washing machine control seat is shown, and due to the limitation of the shape of the drum washing machine control seat, the stroke of a corner bending punch of a conventional drum washing machine control seat bending die is different from the stroke of a side bending punch, so that when the drum washing machine control seat bending die is designed, a height difference exists between the corner bending punch and the side bending punch, which can solve the problem of the puzzles caused by the difference of the strokes between the corner bending punch and the side bending punch, and has the characteristics of simple structure and convenience in manufacturing.
Disclosure of Invention
The invention aims to solve the problems that a height difference exists between a corner bending punch and a side bending punch of the existing bending die of the control seat of the drum washing machine, and the side surface of a product is easy to be damaged during bending, so that the quality of the product is influenced.
The purpose of the invention is realized by the following technical scheme:
a bending die of a washing machine control seat comprises an upper die base, a lower die base, an upper padding plate, a lower padding plate, an upper fixing plate, a lower fixing plate, a pressure plate, a bending male die and a bending female die, wherein the upper padding plate is connected to the lower end of the upper die base; in an initial state, the corner bending punch protrudes downwards under the action of the elastic piece so that the corner bending punch is flush with the side bending punch.
In a preferred embodiment of the present invention, the elastic member is a nitrogen spring.
As a preferable scheme of the invention, the corner bending punch is provided with a guide groove, the guide groove is arranged along the vertical direction, the lower end of the upper padding plate is positioned at the outer side of the corner bending punch and is provided with a limiting block, and the limiting block is provided with a guide block matched with the guide groove.
As a preferable mode of the present invention, the number of the guide grooves is 2, and correspondingly, the number of the guide blocks is 2.
As a preferable scheme of the present invention, the guide block and the limiting block are integrated.
The bending die for the control seat of the washing machine has the advantages that the elastic piece is arranged, so that the corner bending punch is flush with the side bending punch, the elastic piece is compressed under the action of the lower die during bending, the corner bending punch cannot interfere with a workpiece, the problem that the side face of a product is damaged by pulling is solved, and the product quality is effectively guaranteed.
