Description

Technical Field

[0001] This utility model relates to the field of vehicle parts processing equipment, and in particular to a continuous die-cutting edge bending mechanism. Background Technology

[0002] Axle support reinforcement plates are key structural components in vehicle suspension systems. Manufacturers use molds to stamp sheet metal into axle support reinforcement plates. Currently, the processing involves first bending the sheet metal in a bending die, and then feeding it into a blanking die for cutting. However, this requires two molds, resulting in long processing times and production efficiency that cannot meet the needs of large-scale production.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a continuous die-cutting edge bending mechanism.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A continuous die-cutting and bending mechanism includes a base, a lower die, and an upper die. The lower die is mounted on the base, and the upper die is movably arranged above the lower die. The lower die includes a lower die base and a lower module. The lower die base is mounted on the base, and a first cutter and a second cutter are mounted on the top of the lower die base. The lower module is arranged on the top of the lower die base, and a pair of protrusions are provided on the top of the lower module, with a cavity between the protrusions. The upper die includes an upper module, and a second protrusion is provided at the bottom of the upper module. When the lower die and the upper die are closed, the second protrusion is inserted into the cavity between the protrusions.

[0007] Furthermore, the top of the protrusion is flat, and its height is higher than the top surface of the lower module, and the inner surface of the protrusion is set as an inclined surface.

[0008] Furthermore, the outer surface of the second protrusion is set as an inclined surface, and its inclination angle is the same as that of the inner surface of the first protrusion.

[0009] Furthermore, the first and second cutting tools are arranged in the middle of the lower mold base, and the cutting tips of the first and second cutting tools extend into the gap between the lower modules.

[0010] Furthermore, the top height of the first and second cutting tools does not exceed the thickness of the lower module.

[0011] Furthermore, a pair of limiting modules are provided on the base, and the limiting modules are erected on the left and right sides of the top surface of the base.

[0012] Furthermore, a snap-fit ​​groove is provided between the limiting module and the lower mold base.

[0013] Furthermore, the upper width of the snap-fit ​​groove is greater than the lower width.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In the process of preparing the axle support reinforcement plate, the material is placed into the lower mold, and then the press is started to drive the upper mold to move downward. The upper and lower molds close, and the upper and lower molds act on the material to bend it. Then, as the upper mold moves further downward, the middle of the material comes into contact with the first and second cutters to cut the material. The bending and cutting work is completed in one process, which greatly shortens the processing time and improves work efficiency.

[0016] 2. The cavity is formed between protrusion one and protrusion two. The product is bent and deformed in the cavity. Protrusion one is located above the cutting tool. The sheet metal is cut from this position. The cutting tool damages the parts during the cutting process.

[0017] 3. The locking groove between the limiting module and the lower mold base allows the product edge to be located within the locking groove, thereby limiting product displacement and preventing excessive material offset during bending and cutting, thus improving product processing accuracy.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Example:

[0024] A continuous die-cutting edge bending mechanism, such as Figure 1 As shown, the machine includes a base 1, a lower die 2, and an upper die 3. The base 1 is on the worktable of the stamping machine, the lower die 2 is mounted on the base 1, and the upper die 3 is mounted on the punch of the stamping machine. During operation, the material to be processed is placed in the lower die 2, and the upper die 3 moves up and down reciprocating along with the punch. Then, the upper die 3 and the lower die 2 close, causing the material to deform and obtain the desired product.

[0025] like Figure 1 As shown, the lower mold 2 includes a lower mold base 21 and a lower mold module 22. The lower mold base 21 is mounted on the base 1 and serves as the mounting base for other components. Cutting tool 1 23 and cutting tool 24 are mounted at the top center of the lower mold base 21, arranged vertically. During mold closing, as the upper mold 3 presses down, the bottom of the material to be processed contacts the top cutting edges of cutting tools 1 23 and 24, thereby cutting the material.

[0026] like Figure 1 As shown, the lower module 22 is located on top of the lower mold base 21, and its shape is symmetrical about the center of the lower mold base 21. A pair of protrusions 221 are provided on the top of the lower module 22, located in the middle of the lower module 22. The top of each protrusion 221 is a flat surface, higher than the top surface of the lower module 22, and the inner surface of each protrusion 221 is an inclined surface. During mold closing, the protrusions 221 align with the bottom surface of the material, and the material deforms accordingly based on the shape of the protrusions 221.

[0027] like Figure 1 As shown, a cavity is provided between the protrusions 221. The cutting heads of the first cutting tool 23 and the second cutting tool 24 extend into the cavity between the lower modules 22. The top height of the first cutting tool 23 and the second cutting tool 24 does not exceed the thickness of the lower module 22 to prevent the first cutting tool 23 and the second cutting tool 24 from interfering with the bending and deformation of the material.

[0028] like Figure 1 As shown, a pair of limiting modules 4 are provided on the base 1. The limiting modules 4 are located on the left and right sides of the top surface of the base 1, and the limiting modules 4 are positioned vertically. A snap-fit ​​groove 41 is provided between the limiting modules 4 and the lower mold base 21. The upper width of the snap-fit ​​groove 41 is greater than its lower width, and the upper width of the snap-fit ​​groove 41 is equal to the thickness of the material to be processed. During operation, the edge of the material is placed in the snap-fit ​​groove 41, which serves to fix the material, thereby preventing the material from easily moving during deformation and cutting, and avoiding processing errors.

[0029] like Figure 1As shown, the upper die 3 includes an upper module 31, which is fixed to the punch of the stamping machine and can move up and down synchronously with the punch. A pair of protrusions 311 are provided at the bottom of the upper module 31, located in the middle of the bottom. The bottom surface of the protrusions 311 is flat, and the outer surface of the protrusions 311 is sloped, with the slope angle being the same as the slope angle of the inner surface of the protrusion 221. During operation, the upper die 3 and the lower die 2 close, and the protrusions 221 and 311 act on the material, causing the material to deform accordingly.

[0030] Specific work process:

[0031] First, the staff put the material into the lower mold 2. The structure of the product before molding is as follows: Figure 2 As shown, the edge of the material is snapped into the snap-fit ​​groove 41, thereby fixing the material onto the lower module 22. Then, the stamping machine is started, and the punch of the stamping machine presses down. The protrusion 311 of the upper module 31 is inserted between the protrusion 221 of the lower module 22. The cavity between the two is the material forming cavity. Then, the middle part of the material contacts the first cutter 23 and the second cutter 24, cutting the material and forming the product. Its structure is as follows. Figure 3 As shown.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
