Description

Technical Field

[0001] The utility model relates to a dismantling structure of a die punch. Background Art

[0002] The punch is an important component in the punching die. The manufacturer will select a punch of appropriate size according to the punching size of the required product and install the punch on the punch seat for use. At present, the punches on the market are fastened to the punch seat by screws. When multiple punches are set on a die seat, the operator needs to tighten the screws one by one, which leads to low installation and disassembly efficiency. Utility Model Content

[0003] The purpose of the utility model is to overcome the above problems. We provide a detachable structure of a die punch, which can greatly improve the replacement efficiency of the punch.

[0004] To achieve the above-mentioned purpose, the utility model provides a detachable structure of a mold punch, which includes a punch seat, multiple punches and a punch pressure plate. The punch seat is provided with positioning holes that are the same number as the punches, and the positioning holes are arranged side by side and spaced apart. The shape of the positioning holes is non-circular, and the bottom end of the punch has a positioning portion inserted into the positioning hole. The punch is provided with a limiting step above the positioning portion. The punch pressure plate is installed on the punch seat for pressing the limiting step. The punch pressure plate includes a left pressure plate and a right pressure plate that are oppositely arranged. The left pressure plate and the right pressure plate can be slidably spliced ​​together relative to the punch seat to press the limiting step, or the left pressure plate and the right pressure plate can be slidably separated relative to the punch seat to release the pressure on the limiting step.

[0005] In one or more embodiments, a slide seat is provided at the bottom of the left pressure plate and the right pressure plate, and a slide groove cooperating with the slide seat is provided on the punch seat.

[0006] In one or more embodiments, the left pressure plate and the right pressure plate are provided with positioning bolts, and the punch seat is provided with screw holes. When the left pressure plate and the right pressure plate are spliced ​​together, the positioning bolts correspond to the screw holes, and the positioning bolts can be screwed into the screw holes.

[0007] In one or more embodiments, the positioning hole has a shape of a rectangle, a triangle, an ellipse, a trapezoid, a rhombus, a regular hexagon, or a regular pentagon.

[0008] In one or more embodiments, the depth of the positioning hole is 8MM-20MM, and the height of the positioning portion is consistent with the depth of the positioning hole.

[0009] Compared with the background technology, the utility model has the following effects: the installation and disassembly steps of the punch are simplified by adopting the easy-to-disassemble structure. The operator only needs to insert the positioning part of each punch into the positioning hole, and then push the left pressure plate and the right pressure plate to be spliced ​​together, and then hold the punch, which greatly improves the installation and disassembly efficiency of the punch. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the punch of the utility model being installed on the punch seat;

[0011] Figure 2 It is a schematic diagram of the structure of the punch of the utility model when it is disassembled from the punch seat or installed. DETAILED DESCRIPTION

[0012] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0013] See attached Figure 1-2 The present application provides a detachable structure of a mold punch, which includes a punch seat 1, multiple punches 2 and a punch pressing plate. The punch seat 1 is provided with positioning holes 3 that are the same number as the punches, and the positioning holes are arranged side by side and spaced apart. The shape of the positioning holes 3 is non-circular, and the bottom end of the punch 2 has a positioning portion 21 inserted into the positioning hole. After the positioning portion is inserted into the positioning hole, the rotation of the punch can be limited. The punch is located above the positioning portion and a limiting step 22 is provided. The punch pressing plate is installed on the punch seat 1 to press the limiting step 22 to limit the punch from detaching. The punch pressing plate includes two oppositely arranged left and right pressing plates 4 and 5. The left pressing plate 4 and the right pressing plate 5 can be slidably spliced ​​together relative to the punch seat 1 to press the limiting step 22, or the left pressing plate and the right pressing plate can be slidably separated relative to the punch seat to release the pressure on the limiting step. During installation, the user only needs to insert the positioning part of the punch into the positioning hole, and then slide the left pressure plate and the right pressure plate together and press the limit step. The operation is very quick and simple.

[0014] A slide seat 6 is provided at the bottom of the left pressure plate 4 and the right pressure plate 5, and a slide groove 7 cooperating with the slide seat is provided on the punch seat 1. With the cooperation of the slide seat and the slide groove, the left pressure plate and the right pressure plate can slide smoothly relative to the punch seat.

[0015] The left pressure plate 4 and the right pressure plate 5 are provided with positioning bolts 8, and the punch seat 1 is provided with screw holes. When the left pressure plate and the right pressure plate are spliced ​​together, the positioning bolts correspond to the screw holes, and the positioning bolts can be screwed into the screw holes. After the positioning bolts are screwed into the screw holes, the left pressure plate and the right pressure plate are fixed, and the limiting step is kept pressed all the time.

[0016] The shape of the positioning hole 3 is a combination of one or more shapes selected from rectangle, triangle, ellipse, trapezoid, rhombus, regular hexagon, and regular pentagon, which is selected according to actual needs.

[0017] The depth of the positioning hole 3 is 8MM-20MM, and the height of the positioning portion 21 is consistent with the depth of the positioning hole. The depth of the positioning hole is preferably 10MM, 13MM, 15MM, 18MM, etc., to ensure that the positioning portion has a certain insertion depth.

[0018] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
