DETAILED DESCRIPTION

[0022] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0023] Example 1:

[0024] like Figure 1 As shown, an embodiment of the utility model provides a flat steel auxiliary positioning and punching device, including an upper mold assembly and a lower mold assembly, the upper mold assembly includes an upper mold body 11 and an upper core mold 12, the lower mold assembly includes a lower mold body 21 and a lower core mold 22, after the upper mold body 11 and the lower mold body 21 are matched with each other, a workpiece limiting groove 3 is formed between the corresponding upper core mold 12 and the lower core mold 22, and a first reference reference hole 13 and a second reference reference hole 23 are correspondingly provided on the upper core mold 12 and the lower core mold 22. When in use, the first reference reference hole 13 is a reference hole for the drill bit to enter, and the second reference reference hole 23 is an extension hole for the drill bit to be able to penetrate the workpiece.

[0025] In some embodiments, the upper core mold 12 and the lower core mold 22 are detachably connected to the upper mold body 11 and the lower mold body 21, respectively, so that they can be replaced separately, that is, to replace the upper core mold 12 and the lower core mold 22 of different specifications to meet different requirements of drilling position, quantity, and hole diameter.

[0026] Specifically, the upper core mold 12 and the lower core mold 22 are respectively provided with a first limiting groove 14 and a second limiting groove 24 at corresponding positions, that is, the first limiting groove 14 is opened on the lower surface of the upper core mold 12, and the second limiting groove 24 is correspondingly opened on the upper surface of the lower core mold 22. The first limiting groove 14 and the second limiting groove 24 are matched to form a workpiece limiting groove 3. The first limiting groove 14 and the second limiting groove 24 limit the upper core mold 12 and the lower core mold 22 respectively, and realize a detachable connection.

[0027] Specifically, a first display groove 15 is provided on the upper surface of the upper mold body 11 , and the first reference datum hole 13 is displayed through the first display groove 15 , that is, the first reference datum hole 13 is in an open state.

[0028] In some embodiments, a second display slot 25 is provided on the lower surface of the lower mold body 21, and the second reference reference hole 23 is displayed through the second display slot 25.
