Description

Technical Field

[0001] This utility model relates to the field of mold tooling, and more specifically, to a mold that reduces the number of processes. Background Technology

[0002] Bending is a common and critical process in the manufacturing of sheet metal parts, metal brackets, and other workpieces. Traditional bending dies typically employ a step-by-step structure, where one set of dies first performs the material pressing or pre-positioning, and then another set of dies or manual relocation completes the final bending at a second station. This multi-step operation has significant drawbacks: First, it greatly reduces production efficiency and increases the production cycle time per unit; second, the transfer and repositioning of workpieces between multiple stations can easily lead to cumulative errors, making it difficult to guarantee bending accuracy and resulting in poor product consistency; furthermore, multi-step production requires more equipment investment and operators, increasing production costs and management complexity.

[0003] To overcome the aforementioned problems, the industry has been exploring composite mold structures that can integrate multiple operational steps. However, existing composite molds are often complex in structure, expensive to manufacture, and prone to interference between moving mechanisms, posing challenges to stability and reliability. Therefore, there is an urgent need for a new mold structure that is structurally sound, reliable in operation, and can significantly reduce processes while improving bending accuracy and efficiency. Utility Model Content

[0004] Therefore, in order to solve the problem of multiple bending processes in traditional equipment, this utility model provides a mold that reduces the number of processes, and its specific technical solution is as follows:

[0005] A mold that reduces the number of processes, including

[0006] An upper mold structure is provided with a punch structure, which is slidably connected to the upper mold structure. A tension spring assembly is provided on the upper mold structure and is connected to the punch structure. The punch structure is provided with a first inclined surface and a protrusion.

[0007] The lower mold structure includes a sliding block and a spring assembly. The spring assembly is connected to the sliding block, and the sliding block is slidably connected to the lower mold structure. The sliding block has a forming die and a lower inclined wedge. The lower inclined wedge has a second inclined surface, and the forming die has a groove. The first inclined surface and the second inclined surface cooperate to guide the protrusion into the groove. The protrusion and the groove cooperate to bend the workpiece to be processed.

[0008] The aforementioned die, designed to reduce processing steps, integrates the traditional two processes of blanking (or positioning) and bending into a single stamping stroke through a clever wedge structure design. As the punch descends, its first inclined surface engages with the second inclined surface on the sliding block, driving the sliding block to move horizontally to complete blanking or positioning. Subsequently, the protrusion precisely enters the groove of the forming die to complete bending. This process is continuous and automatic, eliminating the need for intermediate workpiece transfer and merging multiple processes into one, thus improving production efficiency. The precise engagement of the first and second inclined surfaces ensures accurate and stable alignment of the protrusion within the punch, allowing it to enter the groove on the sliding block. The synergistic effect of the tension spring and spring assemblies enables automatic resetting of the core moving parts. During the upper die return stroke, the tension spring assembly pulls the punch structure back to its original position; simultaneously, the spring assembly pushes the sliding block back to its original position, preparing for the next stamping. This die, designed to reduce processing steps, solves the problem of excessive bending processes in traditional equipment.

[0009] Furthermore, the upper mold structure includes an upper mold and a inserter; the inserter is disposed on the upper mold, the tension spring assembly is disposed on the inserter, and the tension spring assembly passes through the inserter and is connected to the punch structure.

[0010] Furthermore, the punch structure includes a base and a forming punch; the base is disposed on the upper die, the first inclined surface is disposed on the base, the forming punch is disposed on the base, and the protrusion is disposed on the forming punch.

[0011] Furthermore, the sliding block is provided with a fixing block, the inserter is provided with a third inclined surface, the fixing block is provided with a fourth inclined surface, and a guide space for inserting the inserter is formed between the fixing block and the lower inclined wedge; the third inclined surface and the fourth inclined surface cooperate to guide the inserter to be inserted into the guide space.

[0012] Furthermore, the lower mold structure is provided with a limiting block, which is used to limit the sliding stroke of the sliding block. Attached Figure Description

[0023] 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 "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0025] like Figures 1-5As shown, a mold for reducing processes according to one embodiment of the present invention includes an upper mold structure 1 and a lower mold structure 2; the upper mold structure 1 is provided with a punch structure 3, the punch structure 3 is slidably connected to the upper mold structure 1, the upper mold structure 1 is provided with a tension spring assembly 4, the tension spring assembly 4 is connected to the punch structure 3, the punch structure 3 is provided with a first inclined surface 5 and a protrusion 6; the lower mold structure 2 is provided with a sliding block 7 and a spring assembly 8, the spring assembly 8 is connected to the sliding block 7, the sliding block 7 is slidably connected to the lower mold structure 2, the sliding block 7 is provided with a forming die 9 and a lower inclined wedge 10, the lower inclined wedge 10 is provided with a second inclined surface 41, the forming die 9 is provided with a groove 42, the first inclined surface 5 and the second inclined surface 41 cooperate to guide the protrusion 6 into the groove 42, the protrusion 6 and the groove 42 cooperate to bend the workpiece to be processed.

[0026] The aforementioned die with reduced processes, through a clever wedge structure design, integrates the traditional two processes of pressing (or positioning) and bending into a single stamping stroke for automatic completion. When the punch structure 3 descends, its first inclined surface 5 engages with the second inclined surface 41 on the sliding block 7, driving the sliding block 7 to move horizontally to complete the pressing or positioning. Subsequently, the protrusion 6 precisely enters the groove 42 of the forming die 9 to complete the bending. This process is continuous and automatic, requiring no intermediate workpiece transfer, merging multiple processes into one, thus improving production efficiency. The precise engagement of the first inclined surface 5 and the second inclined surface 41 ensures that the protrusion 6 of the punch structure 3 can accurately and stably align and enter the groove 42 on the sliding block 7. By utilizing the synergistic effect of the tension spring assembly 4 and the spring assembly 8, the core moving parts are automatically reset. When the upper die 11 returns, the tension spring assembly 4 pulls the punch structure 3 back to its original position; simultaneously, the spring assembly 8 pushes the sliding block 7 back to its original position, preparing for the next stamping. This die with reduced processes solves the problem of multiple bending steps in traditional equipment.

[0027] like Figures 1-5As shown, in one embodiment, the upper mold structure 1 includes an upper mold 11 and a insert 12; the insert 12 is disposed on the upper mold 11, the tension spring assembly 4 is disposed on the insert 12, and the tension spring assembly 4 passes through the insert 12 and is connected to the punch structure 3; the punch structure 3 includes a base 31 and a forming punch 32; the base 31 is disposed on the upper mold 11, the first inclined surface 5 is disposed on the base 31, the forming punch 32 is disposed on the base 31, and the protrusion 6 is disposed on the forming punch 32; the sliding block 7 is provided with a fixing block 43, the insert 12 is provided with a third inclined surface 44, the fixing block 43 is provided with a fourth inclined surface 45, and a guide space for inserting the insert 12 is formed between the fixing block 43 and the lower inclined wedge block 10; the third inclined surface 44 and the fourth inclined surface 45 cooperate to guide the insert 12 to be inserted into the guide space. Thus, during the downward movement of the inserter 12, the third inclined surface 44 on it pre-fits with the fourth inclined surface 45 on the fixed block 43, providing precise guidance for the inserter 12 itself. This effectively prevents the inserter 12 from swaying due to lateral forces, enhancing the rigidity and stability of the upper die 11 during partial movement. Before the first inclined surface 5 of the punch fits with the second inclined surface 41 of the lower wedge, the inserter 12 and the fixed block 43 form a first-level guide, which can pre-correct the position, thus laying a better alignment foundation for the subsequent more precise second-level guide (wedge fit) between the punch and the sliding block 7, further ensuring that the protrusion 6 can accurately enter the groove 42.

[0028] like Figures 1-5 As shown, in one embodiment, the lower die structure 2 is provided with a limiting block 46, which is used to limit the sliding stroke of the sliding block 7. In this way, the limiting block 46 can precisely limit the horizontal sliding stroke of the sliding block 7, ensuring that the pressing or positioning position is exactly the same in each stamping process, thereby ensuring the consistency and stability of the product bending dimensions and reducing the scrap rate.

[0029] The technical features of the above 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.

[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
