Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a pin-connected panel punching die comprises a mounting base 1, a mounting groove 102 is formed in the center of the surface of the mounting base 1, a blanking hole 101 is formed in the bottom of the mounting groove 102 in a penetrating manner, telescopic holes 103 are formed in the left side and the right side of the mounting groove 102 in a penetrating manner, a spring 4 is arranged in each telescopic hole 103, a through groove 105 is formed in each of the front side and the rear side of the mounting groove 102 in a penetrating manner, a sliding groove 104 is formed in the top of each telescopic hole 103 in a penetrating manner, a sliding block 6 is slidably mounted in each sliding groove 104, each sliding block 6 is fixedly connected with the inner end of each spring 4, a punching module 2 and a fixing plate 3 are sequentially arranged in the mounting groove 102 from bottom to top, a positioning groove 202 is formed in the upper surface of each punching module 2, each positioning groove 202 penetrates through each punching module 2 along, and the blanking hole 101, the fixing hole 301 and the punching body 201 are coaxial.

Specifically, the punching module 2 has a plurality of, and every kind of 2 shape sizes of punching the module are all the same, but the aperture of the body 201 that punches a hole on every kind of the module 2 that punches a hole is all inequality, so set up, when punching, only need change the module 2 that punches a hole, moreover when production mould, only need produce the body 201 that punches a hole in different apertures alone the module 2 that punches a hole, not only reduce production cycle, the mould manufacturing cost that significantly reduces moreover.

Specifically, fixed plate 3 corresponds from top to bottom with the module 2 that punches a hole, and the outer wall all with the inner wall in close contact with of mounting groove 102, so set up, make fixed plate 3 and the module 2 that punches a hole can be stable fix inside mounting groove 102, avoid punching a hole the in-process module 2 that punches a hole and take place the displacement, and then make the position dislocation that punches a hole.

Specifically, the inner diameter of the fixing hole 301 is larger than the inner diameter of the punching body 201 and smaller than the inner diameter of the positioning groove 202, so that the fixing plate 3 is utilized to fix the thin and narrow strip material in the positioning groove 202, and the punch can penetrate through the fixing hole 301 to punch the strip material.

Specifically, the sealing block 5 is arranged inside the outer end of the telescopic hole 103, so that the spring 4 can be conveniently installed and replaced.

Specifically, the cross section of slider 6 is the L type of inversion, and the inside wall and the fixed plate 3 of slider 6 closely laminate with the module 2 that punches a hole, utilizes the inboard of slider 6 to carry out spacing fixed to fixed plate 3 and the module 2 that punches a hole simultaneously, prevents that fixed plate 3 and the module 2 that punches a hole from reciprocating.

Specifically, the upper surface of the slider 6 is provided with a built-in handle 601, so that the slider 6 can be conveniently slid and moved by the built-in handle 601.

Specifically, the bottom edge of mount pad 1 outwards extends and forms fixed part 7, offers threaded hole 701 on the fixed part 7, so sets up, through the cooperation of screw and threaded hole 701, can be convenient fix a position the mould fixedly.

The working principle is as follows: when in use, the punching module 2 with the proper punching body 201 is selected according to the requirement of the punching aperture, the die is positioned and fixed through the matching of the screw and the threaded hole 701, the slide block 6 is pulled through the built-in handle 601, the elasticity of the spring 4 is overcome, the two slide blocks 6 move in opposite directions until the slide block 6 is completely separated from the mounting groove 102, the punching module 2 is placed in the mounting groove 102, the thin and narrow strip material is placed in the positioning groove 202, the two ends of the strip material penetrate out of the through groove 105, the fixing plate 3 is covered above the punching module 2, the slide block 6 is loosened, the slide block 6 is pushed to move by the elasticity of the spring 4 until the slide block 6 is tightly attached to the fixing plate 6 and the punching module 2, the fixing plate 3 and the punching module 2 are limited and fixed through the slide block 6 to avoid the displacement, the die installation is completed, the strip material is punched through the fixing hole 301 from top to bottom by the punch head, the processed crushed material falls down along the blanking hole 101, and then the bar material is pushed to a proper position through the material passing groove 105, and the punching process is performed again.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
