Description

Technical Field

[0001] The utility model relates to the technical field of blanking dies, in particular to a side cutting and pre-forming structure of a blanking die. Background Art

[0002] A blanking die separates a sheet metal along a closed contour line. The process of taking the material within the contour line as a blanked part is called blanking, and the die that completes the blanking process is called a blanking die. The blanking die includes an upper die base and a lower die base. A cutting tool assembly is provided between the upper die base and the lower die base. During operation, the sheet metal is placed between the upper die base and the lower die base, and after closing the die, the sheet metal can be blanked to complete the blanking.

[0003] Currently, some blanking dies can only achieve the forming of a single part during the side cutting process. Secondly, due to the up-and-down pressing and cutting method used in the traditional solution, it is impossible to synchronously complete the pre-pressing and forming operation for parts with special shape requirements during the side cutting process. Therefore, the processing efficiency of parts still needs to be improved. Based on this, in order to further optimize the processing applicability of the existing blanking die, we propose a side cutting and pre-forming structure of a blanking die. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that it is impossible to synchronously complete the pre-pressing and forming operation for parts with special shape requirements during the side cutting process, and to propose a side cutting and pre-forming structure of a blanking die.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a side cutting and pre-forming structure of a blanking die, including an upper die tool installed on the upper die unit and a lower die tool installed on the lower die unit:

[0007] Among them, the upper die tool includes an upper side cutter and an upper middle cutter fixed on the upper die unit, and the lower die tool includes a lower side cutter and a lower middle cutter fixed on the lower die unit;

[0008] The upper side cutter and the lower side cutter are both distributed along a circular trajectory, and the upper side cutter is located outside the lower side cutter. The upper middle cutter is used to cooperate with the lower middle cutter to divide the circular trajectory to form two forming positions.

[0009] Furthermore, there are forming surfaces on the upper sides of the two lower side cutters, and a forming block adapted to the forming surfaces is fixed on the lower side of the upper die unit.

[0010] Furthermore, the forming surface is an arc surface, and a concave portion adapted to the arc surface is provided on the end surface of the forming block.

[0011] Further, two rows of the lower middle knives are horizontally distributed along the upper end of the lower die unit, and a plurality of the upper middle knives are linearly distributed. The plurality of upper middle knives are inserted into the gaps between the two rows of lower middle knives.

[0012] Further, a blanking plate is further disposed on the side of the lower die unit, and the blanking plate communicates below the movement tracks of each upper side knife and upper middle knife.

[0013] Further, at least one guide post is fixed on both sides of the lower die unit, and guide sleeves adapted to the guide posts are fixed on both sides of the upper die unit.

[0014] Further, hook rods are detachably connected to both sides of the upper die unit and the lower die unit.

[0015] The blanking die side cutting and pre-forming structure proposed by the present utility model has the beneficial effects that: in the present utility model, through the design of the lower middle knives and the upper middle knives, side cutting operations at two stations can be formed to simultaneously complete the side cutting and forming operations of two products, effectively improving the processing efficiency of side cutting of the sheet material.

[0021] Hereinafter, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Reference Figures 1-4 This is an embodiment of the present utility model, which discloses a side cutting and pre-forming structure for a blanking die. Specifically, this structure includes an upper die cutter 2 installed on the upper die unit 1 and a lower die cutter 4 installed on the lower die unit 3:

[0024] Both the upper side cutter 21 and the lower side cutter 41 are distributed along a circular trajectory, and the upper side cutter 21 is located outside the lower side cutter 41. The upper middle cutter 22 is used to cooperate with the lower middle cutter 42 to divide the circular trajectory to form two forming positions.

[0025] In some embodiments, there are forming surfaces 411 on the upper sides of two of the above-mentioned lower side cutters 41 in the present utility model, and a forming block 11 adapted to the forming surface 411 is fixed on the lower side of the upper die unit 1. That is, in this embodiment, by adopting the cooperation of the forming surface 411 and the forming block 11, it is possible to realize the pre-forming operation of the sheet material through the extrusion cooperation of the forming surface 411 and the forming block 11 when the upper die unit 1 and the lower die unit 3 are closed, and realize the integrated operation of side cutting and pre-forming.

[0026] On the basis of the above embodiment, in this embodiment, the forming surface 411 is an arc surface, and a concave portion adapted to the arc surface is provided on the end surface of the forming block 11. That is, in this embodiment, during the side cutting process of the sheet material, the arc surface extrusion forming is performed on some positions of it, that is, the formed product has a flat surface and a convex arc surface portion, so as to improve the processing efficiency.

[0027] Furthermore, in the embodiment of the present utility model, the lower middle cutter 42 is horizontally distributed in two rows along the upper end of the lower die unit 3, and the upper middle cutter 22 is distributed in a plurality along a straight line. A plurality of the upper middle cutters 22 are inserted into the gaps between the two rows of the lower middle cutters 42. Through the design of the two rows of lower middle cutters 42, it is used to realize the forming of two products on both sides at the same time. It should be noted that since the cutters in the present utility model are arranged at intervals, after the side cutting is completed, it is also necessary to remove the connecting part between the two products to obtain the finished product.

[0028] On the basis of the above embodiment, the present utility model further includes a blanking plate 31 arranged on the side of the lower die unit 3. The blanking plate 31 is communicated below the moving trajectories of the upper side cutters 21 and the upper middle cutters 22. The design of the blanking plate 31 is to facilitate the centralized guiding of the cut-off scraps, so as to facilitate the centralized collection and treatment.

[0030] Furthermore, hook rods 5 are detachably connected to both sides of the upper die unit 1 and the lower die unit 3. The hook rods 5 are used to connect a lifting tool, so as to facilitate the separation of the upper die unit 1 and the lower die unit 3.

The overall structure design is simple, greatly optimizing the convenience and efficiency of current part forming.
