Abstract
Description
Technical Field
[0001] The utility model relates to the field of stamping dies, in particular to a cylinder-driven fast-switching punch structure. Background Art
[0002] In the production of continuous dies, some products require repeated switching of the punch to punch holes. The solution in the prior art is to make a set of dies separately according to the workpieces to be punched, and then use a cylinder to control the switching of the entire die. However, this method is too cumbersome, consumes a lot of energy in production, and the cost of mold production is relatively high. If the cylinder is allowed to control the punch separately, the above problem can be solved. Utility Model Content
[0003] The utility model aims to provide a structure for quickly switching a punch driven by a cylinder, so as to solve the problems mentioned in the background technology.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted is: a structure of a cylinder-driven quick-switching punch, comprising a cylinder installed on the side of the mold, an upper rack fixedly connected to the front end of the cylinder, a lower rack slidably connected to the upper rack, a punch fixed below the lower rack, an upper pad installed on the opposite side of the cylinder, a fixed plate and a unloading plate passed by the punch, a spring installed between the lower rack and the fixed plate, and a concave mold plate below the unloading plate, wherein the punch is fixed to the lower rack by a fastener; the upper rack and the lower rack can mesh together, and the teeth of both are trapezoidal teeth.
[0005] When the cylinder is pushed out, the upper rack and the lower rack are disengaged, the lower rack presses against the fixed plate below, the spring is compressed, and the punch extends out of the unloading plate into the concave template; when the cylinder retracts, the upper rack and the lower rack are meshed together, the spring resets, and the punch retracts into the unloading plate with the lower rack.
[0006] Compared with the prior art, the structure of the utility model speeds up the switching speed of the punch, saves the mold manufacturing process, and reduces the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and embodiments.
[0012] Example: See Figure 1-Figure 3 , a structure of a cylinder driven rapid switching punch, comprising a cylinder 1 installed on the side of the mold, an upper rack 2 fixedly connected to the front end of the cylinder 1, a lower rack 3 slidably connected to the upper rack 2, a punch 5 fixed under the lower rack 3, an upper pad 7 installed on the opposite side of the cylinder 1, a fixed plate 8 and a stripper plate 9 fixed under the lower rack 3, a spring 4 installed between the lower rack 3 and the fixed plate 8, and a concave template 10 under the stripper plate 9, wherein the upper rack 2 is limited by the upper pad 7 in the horizontal direction; the punch 5 is fixed to the lower rack 3 by bolts; the punch 5 passes through the fixed plate 8 and the stripper plate 9; the upper rack 2 and the lower rack 3 can be meshed together, and the teeth of both are trapezoidal teeth; the lower end of the spring 4 is fixed to the fixed plate 8, and the upper end is a free end, which is pressed against the lower surface of the lower rack 3; the concave template 10 is fixed to the lower die base 11, and a hole is provided in the middle for the punch 5 to pass through.
[0013] When the punch 5 needs to work, the piston rod of the cylinder 1 is pushed out, the upper rack 2 moves to the right, the upper rack 2 and the lower rack 3 are disengaged, the upper rack 2 presses the lower rack 3 against the fixed plate 8 below, the spring 4 is compressed, and the lower rack 3 drives the punch 5 down to the concave template 10 to complete the blanking; when the punch 5 finishes working, the piston rod of the cylinder 1 retracts, the upper rack 2 moves to the left, the upper rack 2 and the lower rack 3 are engaged with each other, the spring 4 is reset, the punch 5 moves up with the lower rack 3, and the punch 5 retracts into the unloading plate 9.
[0014] It should be pointed out that, based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work are within the scope of protection of the present utility model.
[0015] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary, but not restrictive, and the scope of the present invention is defined by the appended claims rather than the above explanations and descriptions, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
