Abstract
Description
Technical Field
[0001] This utility model belongs to the field of punching technology and relates to a punching die without indentation. Background Technology
[0002] Punching dies are typical single-operation blanking dies, commonly used in metal processing to create holes, concave and convex shapes or other specific geometric contours on metal sheets.
[0003] Currently available punching dies tend to leave indentations on workpieces during punching operations. Utility Model Content
[0004] The purpose of this invention is to solve the above problems and provide a punching die without indentation.
[0005] To achieve the above objectives, this utility model provides a non-marking punching die, including a working disc, on which multiple punching components are equally spaced. The working disc has mounting holes, and each punching component includes a sleeve installed at the mounting hole. The sleeve is fitted with an impact structure, and the lower end of the sleeve has an elastic material layer. The middle of the lower end of the sleeve has a through hole, and the upper end of the sleeve has a flange with a diameter larger than the diameter of the mounting hole. A spring is provided on the outer periphery of the portion of the sleeve that protrudes above the upper surface of the working disc.
[0006] The impact structure includes a pressing part, a main body connected to the pressing part, and a punch fixed on the main body;
[0007] A rubber cylinder is provided on the lower side of the pressing part, and a washer is provided on the lower side of the rubber cylinder. The washer is supported on the flange.
[0008] The beneficial effects of this utility model are as follows:
[0009] The non-marking punching die of this invention, through the above-mentioned structural design, especially the elastic material layer, can effectively prevent indentation on the workpiece during punching operations. Furthermore, the above-mentioned structural design of the impact mechanism and sleeve also helps to ensure the stability and smoothness of the punching operation. Attached Figure Description

[0014] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.
[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.
[0016] Combination Figures 1-4 As shown, this utility model discloses a non-marking punching die, including a working disc 1. Multiple punching components are evenly spaced on the working disc 1. The working disc 1 is provided with mounting holes 3. The punching component 2 includes a sleeve 4 installed at the mounting hole 3. The lower end of the sleeve 4 has an elastic material layer 41. The middle part of the lower end of the sleeve 4 is provided with a through hole 42. The upper end of the sleeve 4 is provided with a flange 43. The diameter of the flange 43 is larger than the diameter of the mounting hole 3. A spring 6 is provided on the outer periphery of the part of the sleeve 4 that is higher than the upper surface of the working disc 1.
[0017] The sleeve 4 of this utility model is equipped with an impact structure 5. The impact structure 5 includes a pressing part 51, a main body 52 connected to the pressing part 51, and a punch 53 fixed on the main body 52. A rubber cylinder 54 is provided on the lower side of the pressing part 51, and a washer 55 is provided on the lower side of the rubber cylinder 54. The washer 55 is supported on the flange 43.
[0018] The working principle of this non-marking punching die is as follows:
[0019] The workpiece to be punched is placed below the elastic material layer 41. When the impact structure 5 receives the punching force, it moves downward, causing the sleeve 4 to move downward and compressing the spring 6. After the lower end of the sleeve 4, i.e., the elastic material layer 41, presses the workpiece, the pressing part 51 continues to move downward. Under the action of the pressing part 51 and the washer 55, the rubber sleeve 54 deforms and compresses, causing the pressing part 51, the main body 52, and the punch 53 to move downward within the sleeve 4. Finally, the punch 53 passes through the through hole 42 to complete the punching operation.
[0020] The non-marking punching die of this invention, through the above-mentioned structural design, especially the provision of the elastic material layer 41, can effectively prevent indentations on the workpiece during punching operations. Furthermore, the above-mentioned structural design of the impact mechanism 3 and the sleeve 4 also helps to ensure the stability and smoothness of the punching operation.
[0021] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
