AI Technical Summary
When the parts have high edge lines and the length of the waste material is long, the prior art cannot achieve smooth edge lines, resulting in too long waste material being discharged smoothly. The step distance after the overall cutting is used is increased, and the discharge height is poor.
A waste knife structure including connecting blocks, movable knife blocks, upper module cutter blocks, elastic parts, limit blocks and waste knife body is designed. The upper module cutter block is cut in segments through the upper module cutter block and the movable knife block combination. Use nitrogen springs to provide elastic force to ensure smooth cutting of the trimming line.
The bright cut-off of the edge trimming line is achieved, the production efficiency and product quality is improved, the problem of increasing pace is avoided, and the smooth discharge of waste is ensured.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stamping dies, in particular to a waste cutter structure which can ensure a smooth trimming line. Background Art
[0002] When the part edge requirements are relatively high, the scrap length is long, and there cannot be a joint edge on the trimming line. In this case, the scrap is too long and cannot be discharged smoothly. Add a scrap knife, the upper die knife block has a height difference, the cut edge is not smooth, and the quality cannot meet the part requirements. If the whole is cut off first, the scrap slides down a distance and then cut with a scrap knife, the step distance will be increased and the discharge height is not good. Therefore, it is necessary to develop a scrap knife structure that ensures a smooth trimming line and completes segmented cutting. Utility Model Content
[0003] In order to overcome the disadvantages of first cutting the whole material and then cutting it with a waste knife after the waste material slides down a certain distance, which increases the step distance and has a poor material discharge height, the utility model aims to provide a waste knife structure with segmented cutting to ensure smooth trimming lines.
[0004] The technical implementation scheme of the utility model is: a waste knife structure that ensures smooth trimming lines, comprising a connecting block, a movable knife block, an upper die knife block, an elastic member, a limit block and a waste knife body, the connecting block is slidably provided with an upper die knife block, the upper die knife block is fixed on an upper die seat of a mold, a movable knife block is rotatably provided on the upper die knife block, the movable knife block is rotatably connected to the connecting block, an elastic member is provided on the top of the connecting block, the elastic member is mounted on the upper die seat of the mold, the lower end of the elastic member is in contact with the connecting block, a limit block is provided on the lower die seat of the mold, and the waste knife body is provided on the limit block.
[0005] In one embodiment, the elastic member is a nitrogen spring.
[0006] In one of the embodiments, the upper die knife block is rotatably provided with a movable knife block via a bolt.
[0007] In one embodiment, the upper die cutter block is fixed to the upper die base of the mold by screws.
[0008] The utility model has the following advantages: the utility model first performs a cutting operation through the upper die knife block, and then further realizes bright cutting of the product trimming line through the cooperation of the movable knife block and the waste knife body, and achieves good results in actual production.

[0013] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.
[0014] Example: Figure 1-Figure 3 As shown, a waste knife structure for ensuring smooth trimming line includes a connecting block 1, a movable knife block 2, an upper die knife block 4, an elastic member 5, a limit block 6 and a waste knife body 7. The upper die knife block 4 is slidably arranged on the connecting block 1, and the upper die knife block 4 is fixed on the upper die seat of the mold by screws. The upper die knife block 4 is rotatably arranged with the movable knife block 2 by bolts 3. The movable knife block 2 is rotatably connected to the connecting block 1. An elastic member 5 is arranged on the top of the connecting block 1, and the elastic member 5 is a nitrogen spring. The elastic member 5 is installed on the upper die seat of the mold, and the lower end of the elastic member 5 contacts the connecting block 1. A limit block 6 is arranged on the lower die seat of the mold, and the waste knife body 7 is arranged on the limit block 6.
[0015] The connecting block 1, the movable knife block 2, the upper die knife block 4 and the elastic member 5 move downward with the upper die seat of the mold, and the upper die knife block 4 cuts the edges along the contour of the product. As the upper die seat continues to move downward with the upper components, the waste knife body 7 squeezes the connecting block 1, and the nitrogen spring is compressed. The movable knife block 2 rotates around the bolt 3 and moves downward to cooperate with the waste knife body 7 to cut off the waste. When the upper die seat is reset upward, the nitrogen spring resets and squeezes the connecting block 1 downward, and at the same time drives the movable knife block 2 to reset. The device has a simple structure and can smoothly cut off the waste in sections.
[0016] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
