Description

Technical Field

[0001] This utility model relates to the field of stamping process technology, specifically to a bevel cutting die. Background Technology

[0002] In the field of cold stamping technology, when sheet metal, bar stock, tubes, and other materials are required to be cut at bevels, they are usually produced by mechanical processing, such as gas cutting or wire cutting with a cutting machine, or sheet metal is often processed by cold stamping dies.

[0003] For the cutting of the vertical edges of a workpiece, the usual method is to tilt or turn the workpiece. When multiple vertical surfaces of a workpiece need to be cut, in order to avoid directly causing deformation of the vertical surfaces, the workpiece needs to be flipped multiple times before cutting, or a double tool is added for cutting the side and top surfaces. This method is very costly and unstable. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency bevel cutting mold.

[0005] To solve the above-mentioned technical problems, this utility model provides a bevel cutting die, comprising:

[0006] The upper mold assembly includes an upper mold base; the bottom of the upper mold base is provided with a cavity mold, and the inner sidewall of the cavity mold is provided with an inwardly protruding cutting slope, the protrusion of the cutting slope gradually narrows from the bottom of the cavity mold to the opening, and the upper mold base is provided with a mold base auxiliary column for positioning.

[0007] The lower die assembly includes a lower die base; a punch is mounted on the bottom of the lower die base, and a cutting groove is provided on the outer side wall of the punch. The cutting slope and the cutting groove are used to cut the vertical edge of the workpiece; a die base positioning post is provided on the lower die base for positioning.

[0008] Preferably, both sides of the cut slope are perpendicular to the slope surface of the cut slope;

[0009] Both sides of the cutting groove are perpendicular to the bottom surface of the cutting slope.

[0010] The two sides of the cutting groove correspond one-to-one with the two sides of the cutting slope.

[0011] Preferably, the die includes a workpiece machining groove and a die cutting surface;

[0012] The punch includes a workpiece machining protrusion and a punch cutting surface;

[0013] The workpiece processing groove and workpiece processing protrusion are used to press and fix the workpiece body, and the die cutting surface and punch cutting surface are used to press the workpiece edge and cut off the waste material of the workpiece and the workpiece edge.

[0014] Preferably, the slope of the cutting slope is 85°.

[0015] Preferably, the upper mold base has mold base positioning grooves at all four corners of its bottom;

[0016] The lower mold base has upward-extending mold base positioning posts at its four top corners;

[0017] The mold base positioning pin extends into the mold base positioning groove.

[0018] Preferably, the upper mold base is provided with downwardly extending mold base auxiliary columns around the cavity mold;

[0019] The lower die holder has auxiliary grooves around the punch;

[0020] The mold base auxiliary column extends into the mold base auxiliary groove.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] This invention improves upon the existing cutting method by replacing it with oblique cutting stamping. A cutting slope is provided at the upper die base cutting position corresponding to the vertical surface, and a cutting groove is provided at the corresponding lower die base position. When the upper die assembly is pressed down, the two oblique cutting edges of the cutting slope and the two vertical edges of the cutting groove gradually intersect, forming a top-to-bottom shearing effect on both sides of the vertical surface to be cut. The cut-off vertical surface material falls into the gap between the cutting slope and the cutting groove as the cutting slope moves down, and is cut off as the upper die base falls. During the cutting process, the perimeter of the cut is always squeezed by the die and punch to prevent deformation. Using this method to cut the vertical surface of the workpiece not only eliminates the need for a complex transverse cutting transmission structure, reducing debugging time, but also eliminates the need for a separate processing step, allowing it to be combined with other stamping processes to improve processing speed.

[0037] This utility model provides a bevel cutting mold, comprising:

[0038] The upper mold assembly includes an upper mold base 1; the bottom of the upper mold base 1 is provided with a concave mold 2, and the inner side wall of the concave mold 2 is provided with an inwardly protruding cutting slope 3.

The cutting slope 3 and the cutting groove 7 are used to cut the vertical edge of the workpiece; a die base positioning post 8 for positioning is provided on the lower die base 5.

[0040] Preferably, both sides of the cutting slope 3 are perpendicular to the slope surface of the cutting slope 3;

[0041] Both sides of the cutting groove 7 are perpendicular to the bottom surface of the cutting slope 3.

[0043] Preferably, the die 2 includes a workpiece machining groove 21 and a die cutting surface 22;

[0044] The punch 6 includes a workpiece machining protrusion 61 and a punch cutting surface 62;

[0045] The workpiece processing groove 21 and the workpiece processing protrusion 61 are used to press and fix the workpiece body, and the die cutting surface 22 and the punch cutting surface 62 are used to press the workpiece edge and cut off the waste material of the workpiece and the workpiece edge.

[0046] Preferably, the slope of the cutting slope 3 is 85°.

[0047] Preferably, the upper mold base 1 has mold base positioning grooves 9 at all four corners of its bottom;

[0048] The lower mold base 5 is provided with mold base positioning posts 8 extending upward at the four corners of its top;

[0049] The mold base positioning pin 8 extends into the mold base positioning groove 9.

[0050] Preferably, the upper mold base 1 is provided with downwardly extending mold base auxiliary columns 4 around the cavity mold 2;

[0051] The lower die base 5 has a die base auxiliary groove 10 around the punch 6;

[0052] The mold base auxiliary column 4 extends into the mold base auxiliary groove 10.

[0053] Preferably, the length of the mold base positioning column 8 is greater than the length of the mold base auxiliary column 4.

[0054] Preferably, the number of mold base positioning posts 8 and mold base auxiliary posts 4 are both four;

[0055] The four auxiliary columns 4 of the mold base are located inside the four positioning columns 8 of the mold base.

[0056] To better illustrate the technical effects of this utility model, the present utility model provides the following specific embodiments to explain the above technical process:

[0057] Example 1: A bevel cutting die, such as Figure 1 As shown, it includes an upper mold assembly and a lower mold assembly;

[0058] like Figure 2 As shown, a die cavity 2 is provided at the bottom of the upper die base 1, and a cutting slope 3 is provided in the die cavity 2; as Figure 3 As shown, a punch 6 is installed at the bottom of the lower die base 5, and a cutting groove 7 is provided on the punch 6; the two sides of the cutting slope 3 and the cutting groove 7 that meet each other form a shearing effect when the die is pressed down. When the upper die base 1 is fully pressed down, the cutting slope 3 can fall completely into the cutting groove 7, thereby shearing the vertical edge of the workpiece (such as...). Figure 4 (as shown in Part A).

[0059] The upper mold base 1 and the lower mold base 5 are respectively provided with mold base auxiliary pillar 4 and mold base positioning pillar 8; the mold base positioning pillar 8 extends into the mold base positioning groove 9, which can limit the movement direction between the upper mold base 1 and the lower mold base 5; the mold base auxiliary pillar 4 extends into the mold base auxiliary groove 10, which can help limit the movement direction between the upper mold base 1 and the lower mold base 5; the mold base auxiliary pillar 4 and the mold base positioning pillar 8 work together to move the upper mold base 1 and the lower mold base 5 more accurately when the oblique cutting mold is running.

[0060] The workpiece body is pressed and fixed by the workpiece machining groove 21 and the workpiece machining protrusion 61, and the edge of the workpiece is pressed by the die cutting surface 22 and the punch cutting surface 62 to cut off the waste material (such as...) from the workpiece and the outer side of the workpiece. Figure 4 (as shown in Part B).

[0061] In this embodiment, both the vertical surface and the outer periphery of the workpiece are waste materials that need to be removed. When the cutting slope is completely lowered, it works in conjunction with the outer die cutting surface to achieve a single stamping, simultaneously removing the vertical surface and the outer periphery waste materials. Moreover, the removed waste materials are in a single piece, eliminating the need for waste material sorting and improving work efficiency.

[0062] This invention improves upon the existing cutting method by replacing it with oblique cutting stamping. A cutting slope is provided at the upper die base cutting position corresponding to the vertical surface, and a cutting groove is provided at the corresponding lower die base position. When the upper die assembly is pressed down, the two oblique cutting edges of the cutting slope and the two vertical edges of the cutting groove gradually intersect, forming a top-to-bottom shearing effect on both sides of the vertical surface to be cut. The cut-off vertical surface material falls into the gap between the cutting slope and the cutting groove as the cutting slope moves down, and is cut off as the upper die base falls. During the cutting process, the perimeter of the cut is always squeezed by the die and punch to prevent deformation. Using this method to cut the vertical surface of the workpiece not only eliminates the need for a complex transverse cutting transmission structure, reducing debugging time, but also eliminates the need for a separate processing step, allowing it to be combined with other stamping processes to improve processing speed.

[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
