Preferably, the upper end of the guide pin is of a conical structure, so that when a workpiece is placed, the upper end of the guide pin extends into the hollow hole of the workpiece.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments will be briefly described below, it is obvious that the drawings in the following description are only two of the embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic diagram of an embodiment of the present invention;
FIG. 2 is an enlarged view of a portion A of FIG. 1;
fig. 3 is a schematic view of a workpiece according to an embodiment of the present invention.
The device comprises a hydraulic cylinder 1, a top plate 2, a pressing plate 3, a guide column 4, a discharging column 5, a discharging plate 6, a base table 7, a guide pin 8, a base 9, a workpiece 10, a contact plate 11 and a position withdrawing hole 12.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely preferred embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
As shown in FIG. 1, the embodiment of the present invention includes a lower tool and an upper tool.
The lower tool comprises a base 9, a base table 7 and a guide column 4; the base platform 7 is arranged on the upper surface of the base 9, a guide pin 8 is upwards arranged on the upper surface of the base platform 7 corresponding to the hollow hole of the iron sheet, and the guide column 4 is upwards fixed on the base 9 outside the base platform 7.
