The utility model relates to an embodiment, the guiding hole has been seted up in the four corners correspondence of lifter plate.

The utility model relates to an embodiment, the guide post is multistage concatenation formula.

In an embodiment of the present invention, the casing fixing column is connected to the clamp through the bolt lock.

The utility model relates to an embodiment, install four reset spring on the base altogether, four reset spring connecting holes have been seted up in the lower surface correspondence of lifter plate.

The utility model has the advantages that: the utility model provides a motor casing cut-out press installs this device on the punching machine, then overlaps the motor casing on the casing fixed column, and the last mould downstream of punching machine pushes down the motor casing, and the guide post of this device penetrates in the upper mould, thereby goes up the mould and take lifter plate downstream in downstream area after that, and then relative lifter plate of punching press convex part and casing fixed column upward movement to upwards withstand the casing punching press trompil, realized by the inside outside punching a hole of motor casing. The burr is effectively prevented from being formed on the inner wall of the motor shell, so that the burr appears on the outer wall of the motor shell, the polishing difficulty caused by the limitation of the inner space of the motor shell is avoided during polishing, and the polishing is convenient and smooth; the motor can stably run for a long time, and the service life is prolonged.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1 to 5, the utility model provides a motor casing punching die, which comprises a base 2, wherein four corners of the base 2 are provided with guide posts 3, and the base 2 is provided with a return spring 8; a fixing block 7 with an inverted L-shaped section is arranged in the middle of the rear part of the base 2, the opening end of the fixing block 7 faces the right front, and a stamping convex part 6 protrudes from the front part of the upper surface of the fixing block 7; a lifting plate penetrates through the guide column 3, a C-shaped clamp 5 is fixed at the rear part of the lifting plate 1, an arc-shaped groove 13 is formed in the front part of the lifting plate 1, the lifting plate can be kept at a certain distance from a fixed column of a machine shell, a shell of a motor can penetrate through the lifting plate to facilitate smooth punching, a rectangular first through hole 11 is formed in the position, corresponding to the fixed block 7, of the rear part of the lifting plate 1, a second through hole 51 communicated with the first through hole 11 is formed in the clamp 5, the stamping convex part can be guaranteed to move up and down, and punching is completed; the punching machine is characterized in that a machine shell fixing column 4 is fixed on the clamp 5, the rear portion of the machine shell fixing column 4 is hollow, a punching hole 41 is formed in the rear portion of the machine shell fixing column 4 and located above the punching convex portion 6, the punching convex portion 6 penetrates into the punching hole 41, and therefore when the punching convex portion is jacked up, the position, needing punching, of the shell of the motor can be jacked up smoothly, and punching is finished smoothly.

Referring to fig. 1, fig. 3 and fig. 4, in an embodiment of the present invention, guide holes 14 are correspondingly formed at four corners of the lifting plate 1 to guide the lifting of the lifting plate.
