Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a punching die for irregularly shaped parts. Background Technology

[0002] The irregularly shaped plate-like parts have circular holes and irregularly shaped holes. During the manufacturing process, they need to be positioned and then the waste edges need to be trimmed.

[0003] In current industrial production, cutting mainly relies on manual operation by workers. Since the positioning of irregularly shaped parts depends on manual operation during the cutting process, the cutting accuracy is entirely determined by the experience of the workers, resulting in low work efficiency and unstable product quality.

[0004] Chinese Patent Publication No. CN115519620A discloses a multi-dimensional irregular-shaped cutting device and its cutting method, as well as an irregular-shaped product production line, relating to the field of customized product manufacturing technology. The multi-dimensional irregular-shaped cutting device includes a base, a cutting mechanism, a displacement mechanism, a page-turning mechanism, and a mounting frame. The cutting mechanism and the displacement mechanism are spaced apart and both are mounted on the base. The displacement mechanism is connected to the mounting frame, which is used for mounting customized products and fixing the spine of the customized products. The base is provided with a worktable. The page-turning mechanism is mounted on the mounting frame and is used to turn the pages of the customized products when the displacement mechanism moves the mounting frame closer to the cutting mechanism, so that the customized pages overlap on the worktable. The cutting mechanism is used to cut the customized pages on the worktable.

[0005] It can be seen that the above-mentioned cutting device uses multiple mechanisms to work together, its structure is too complicated, and it can only cut the set irregular parts, so its applicability is relatively poor. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a punching die for irregularly shaped parts that is highly applicable and has a compact structure.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A punching die for irregularly shaped parts includes a block-shaped body, characterized in that it further includes a floating positioning component and a cutter. The upper part of the body has a positioning structure for positioning the irregularly shaped parts. The floating positioning component is connected to the body and can be embedded in the hole structure of the irregularly shaped parts to achieve a tight fit and positioning connection. The cutter is connected to the edge of the body and the cutting edge of the cutter is located at the punching position of the irregularly shaped parts.

[0009] In the aforementioned punching die for irregularly shaped parts, the floating positioning assembly includes a positioning rod, a connecting block, and a spring. The main body has a positioning hole that extends through it from top to bottom. The middle part of the positioning rod passes through the positioning hole, and the upper end of the positioning rod extends out of the positioning hole. The upper end of the positioning rod has a positioning part that can tightly fit with the hole structure of the irregularly shaped part. The connecting block is located at the lower part of the main body, and the upper end of the connecting block is connected to the positioning rod.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that when a component is said to be "mounted on" another component, it can be directly mounted on the other component or may be interspersed with a component. When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figure 1 and Figure 2 and Figure 3 As shown, the punching die for this irregular part includes a block-shaped body 1, a floating positioning component, and a cutter 2. The upper part of the body 1 has a positioning structure for positioning the irregular part. The floating positioning component is connected to the body 1. The floating positioning component can be embedded in the hole structure of the irregular part and can achieve a tight fit and positioning connection for the irregular part. The cutter 2 is connected to the edge of the body 1 and the cutting edge 2b of the cutter 2 is located at the punching position of the irregular part.

[0028] The punching die for this irregularly shaped part creatively uses a floating positioning component to form a tight fit with the circular hole of the irregularly shaped part.

[0029] In the initial state, the floating positioning component is at its highest point. At this time, irregularly shaped parts can be easily connected to the floating positioning component and positioned.

[0030] After the stamping equipment presses down, the irregular part and the floating positioning component move down together. After the irregular part comes into contact with the cutter 2, the stamping equipment continues to apply pressure so that the waste edge of the irregular part can act with the cutting edge 2b of the cutter 2, and finally the waste edge is stably cut off.

[0031] The floating positioning assembly includes a positioning rod 3, a connecting block 4, and a spring 5. The body 1 has a positioning hole 1a that runs through it from top to bottom. The middle part of the positioning rod 3 passes through the positioning hole 1a. The upper end of the positioning rod 3 extends out of the positioning hole 1a and has a positioning part 3a at the upper end that can tightly fit with the hole structure of irregular parts. The connecting block 4 is located at the lower part of the body 1 and the upper end of the connecting block 4 is connected to the positioning rod 3. The spring 5 is connected to the lower part of the connecting block 4.

[0032] This structure allows the positioning rod 3 to be replaced, thus adapting to different irregularly shaped parts.

[0033] The size of the connecting block 4 is larger than the size of the positioning hole 1a.

[0034] This structure can prevent the positioning rod 3 from moving excessively upward under the elastic force of spring 5.

[0035] The positioning part 3a includes an inlet section 3a1, a positioning section 3a2, and a protruding edge 3a3 arranged from top to bottom. The inlet section 3a1 is shaped like a frustum of a cone and its upper end is smaller than its lower end. The positioning section 3a2 is cylindrical and its lower end is flush with the outer side of the positioning section 3a2. The protruding edge 3a3 protrudes annularly from the outer side of the positioning section 3a2.

[0036] The inlet segment 3a1 can be stably and smoothly embedded into the hole of the irregular part. Since the positioning segment 3a2 matches the hole of the irregular part, the irregular part can form a stable positioning connection relationship after cooperating with the positioning segment 3a2.

[0037] The raised edge 3a3 is used to block irregularly shaped parts and prevent them from falling off from below.

[0038] The inlet section 3a1, the positioning section 3a2, the protruding edge 3a3, and the positioning rod 3 are an integral structure.

[0039] This effectively improves its structural compactness.

[0040] The lower end of the positioning rod 3 has a connecting hole 3b, and the connecting block 4 has a through connecting hole 4a. It also includes a positioning screw 6, which includes a threaded connecting section 6a and a head 6b. The size of the threaded connecting section 6a is smaller than the size of the head 6b. The threaded connecting section 6a is embedded in the connecting hole 3b of the positioning rod 3 and the two are threadedly connected. The connecting hole 4a on the connecting block 4 is a stepped hole, and the head 6b abuts against the stepped hole.

[0041] After the positioning screw 6 passes through and connects to the first connecting hole 3b and the second connecting hole 4a, it can stably connect the positioning rod 3 and the connecting block 4 together. At the same time, since the positioning screw 6 is not exposed, its structure is relatively compact.

[0042] The body 1 also has a limiting hole 1b that is adjacent to and parallel to the positioning hole 1a. The cutter 2 is matched with the limiting hole 1b and is located at the limiting hole 1b. The lower end of the cutter 2 is located directly above the connecting block 4.

[0043] The positioning part 3a has a planar contact surface 3a4 on its side, and the cutter 2 has a planar contact surface 2a on its inner side. The contact surface 3a4 and the contact surface 2a are in surface contact, and the cutter 2 has a cutting edge 2b on its outer side for cutting irregularly shaped parts.

[0044] This structure can prevent the positioning rod 3 and the cutter 2 from rotating during operation.

[0045] The length of the cutter 2 is greater than the height of the body 1.

[0046] When the lower end of the cutter 2 is flush with the lower end of the body 1, the upper end of the cutter 2 is flush with the convex edge 3a3.

[0047] This structure allows irregularly shaped parts to gradually come into contact with the cutter 2, avoiding rigid contact and effectively improving cutting stability.

[0048] The punching die for this irregularly shaped part is easy to assemble and the part can be easily changed. At the same time, the die has high mass production capability and stability, thus improving production efficiency.

[0049] In addition, the positioning part at the top of the positioning rod is at its highest point in the initial state, which facilitates the installation of irregular parts. During operation, the spring acts as a buffer to avoid rigid contact between the punch head and the cutter, further improving its operational stability.

[0050] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
