The difference between the present embodiment and the first and second embodiments is that the die device 1 is connected to the moving device 51, the moving device 51 is fixed to the base 8, and the moving device 51 can drive the die device 1 to move up and down, so that not only can the plate be stamped, but also the stamped product can be trimmed, and the present embodiment is simple and easy to operate, and has strong practicability; the moving device 51 may be a spiral lifting device, an air cylinder lifting device, or the like in the prior art, and the invention does not need any improvement to this, and is not described herein; when the moving device 51 is adopted, the invention is not matched with a press machine for use any more, the production cost is further reduced, and the equipment as a whole is convenient to transport; when the punching device does not need to be moved, the moving device 51 may also be fixed on the ground or the working table, and the technician may make a specific selection according to specific situations, which is not described in detail herein.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any minor modifications, equivalent replacements and improvements made to the above embodiment according to the technical spirit of the present invention should be included in the protection scope of the technical solution of the present invention.
