Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die fan-shaped strip adjustment structure and a stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). With the rapid development of the metal industry and the widespread application of metal products in industries such as aviation, aerospace, electronics, machinery, shipbuilding and automobiles, stamping dies are widely used in various industries.

[0003] Stamping dies can be classified according to the degree of process combination into: single-operation dies, progressive dies, and compound dies. Among them, progressive dies are widely used due to their high production efficiency, which greatly reduces product production costs, and their stable and reliable quality. However, for automotive electronic connector plugs, the strip material is prone to fan-shaped deformation during the actual production process of stamping progressive dies. This fan-shaped deformation affects the dimensional accuracy, shape quality, and assembly performance of the final product, resulting in a decrease in the final product qualification rate and an increase in production costs. Commonly, fan-shaped deformed strip material is divided into inner fan-shaped strip material and outer fan-shaped strip material with completely opposite bending directions. For these two different types of fan-shaped strip material, the industry generally uses the method of replacing die parts to correct the inner or outer fan-shaped strip material. This requires a lot of time for the disassembly, debugging, and reinstallation of the die, resulting in excessive production interruption time, a significant reduction in production efficiency, and an increase in die maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a stamping die fan-shaped strip adjustment structure and a stamping die. This stamping die fan-shaped strip adjustment structure eliminates the need to disassemble the die and replace parts to straighten different types of fan-shaped strips, thereby improving production efficiency.

[0005] To achieve the above objectives, this utility model provides a fan-shaped strip adjustment structure for stamping dies, comprising:

[0006] An adjusting rod, wherein a groove is provided on the top surface of one end of the adjusting rod, and two mutually symmetrical and upwardly inclined first and second inclined surfaces are provided at both ends of the groove;

[0007] Two fan-shaped adjusting parts are arranged back-to-back in the lower template of the stamping die. An adjusting block is provided at the center of the top surface of each fan-shaped adjusting part, and a third inclined surface is provided on the bottom surface of each fan-shaped adjusting part, which is in contact with the first inclined surface or the second inclined surface.

[0008] A blank holder is provided in the stripper plate of the stamping die. The adjusting rod is laterally displaced to drive the longitudinal displacement of the fan-shaped adjusting part, so that the adjusting block cooperates with the blank holder to squeeze and straighten the fan-shaped strip.

[0009] Optionally, the fan-shaped adjustment part includes horizontal and vertical portions arranged in an L-shape, and the adjustment block is disposed on the top surface of the vertical portion.

[0010] Optionally, a spring is provided on the top surface of the horizontal portion of the sector-shaped adjusting part.

[0011] Optionally, the stamping die fan-shaped strip adjustment structure further includes a pressure plate fixed in the lower template, the pressure plate being connected to the end of the spring away from the horizontal part.

[0012] Optionally, the other end of the adjusting rod is provided with an adjusting mechanism, which includes an adjusting rod base fixed to the top of the lower mold base and an adjusting screw rotatably disposed on the adjusting rod base. The adjusting screw is configured to drive the adjusting rod to move laterally by rotation.

[0013] Optionally, the cross-section of the adjusting block is set to an isosceles trapezoid.

[0014] Optionally, the adjusting block is detachably connected to the sector-shaped adjusting part.

[0015] Optionally, the first, second, and third inclined surfaces are all configured as polished surfaces.

[0016] The second aspect of this utility model provides a stamping die, comprising:

[0017] Stamping die assembly;

[0018] The above-mentioned stamping die fan-shaped strip adjustment structure.

[0019] Optionally, the stamping die assembly includes, from top to bottom, an upper cover plate, an upper die base, an upper pad plate, an upper clamping plate, a stripper back plate, a stripper plate, a lower die plate, a lower pad plate, and a lower die base.

[0020] Through the above technical solution, the stamping die fan-shaped strip adjustment structure provided by this utility model uses the lateral movement of the adjustment rod to utilize the first and second inclined surfaces symmetrically set on the top surface of one end of the rod to cooperate with the third inclined surfaces of the bottom surfaces of two back-to-back fan-shaped adjustment parts. The groove serves as a clearance groove. When the adjustment rod moves back and forth laterally, it can drive the two fan-shaped adjustment parts to move longitudinally to produce height differences. The adjustment blocks on the top surfaces of the two fan-shaped adjustment parts cooperate with the pressing inserts in the stripper plate, thereby applying a squeezing and straightening force to the inner or outer fan-shaped strip. This can reduce the replacement of fan-shaped adjustment parts, improve die accuracy, product quality, and production efficiency. Attached Figure Description

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0035] like Figure 1-4 As shown, this utility model provides a fan-shaped material strip adjustment structure for stamping dies, including an adjustment rod 1, two fan-shaped adjustment parts 2, and a pressing insert 7.

[0036] Specifically, the top surface of one end of the adjusting rod 1 is provided with a groove 11, and the two ends of the groove 11 are provided with two mutually symmetrical and upwardly inclined first slopes 12 and second slopes 13. The two fan-shaped adjusting parts 2 are arranged back to back in the lower template of the stamping die. The center of the top surface of the fan-shaped adjusting part 2 is provided with an adjusting block 3, and the bottom surface of the fan-shaped adjusting part 2 is provided with a third slope 21 that fits against the first slope 12 or the second slope 13. The pressing insert 7 is provided in the stripper plate of the stamping die. The adjusting rod 1 moves laterally to drive the longitudinal displacement of the fan-shaped adjusting part 2, so that the adjusting block 3 cooperates with the pressing insert 7 to squeeze and straighten the fan-shaped strip. Through the cooperation of the first slope 12 or the second slope 13 with the third slope 21, when the adjusting rod 1 moves laterally, one of the fan-shaped adjusting parts 2 moves longitudinally upward and the other fan-shaped adjusting part 2 moves longitudinally downward. This slope cooperation mechanism allows the longitudinal movement of the fan-shaped adjusting part 2 to be controlled by simple lateral adjustment during the stamping process.

[0037] The products in this utility model mainly refer to automotive electronic connectors and plugs that are prone to fan-shaped deformation of the strip during the actual production process of stamping progressive dies. Fan-shaped deformed strips can be divided into those with completely opposite bending directions, such as... Figure 5 The outer fan material strip 9 and such Figure 6 8. Inner fan material belt.

[0038] Combination Figure 4As shown, the stamping die of this utility model consists of, from top to bottom, an upper cover plate, an upper die base, an upper pad plate, an upper clamping plate, a stripper back plate, a stripper plate, a lower die plate, a lower pad plate, and a lower die base. This utility model is installed in the lower die plate of the stamping die. As the stamping die closes, it contacts the metal material in the middle of the strip, causing the material to flow and extruding and straightening the fan-shaped strip. This effectively eliminates the fan-shaped deformation of the strip, ensuring that the dimensional accuracy and shape stability of the product are within the tolerance range, and improving the product qualification rate.

[0039] The present invention discloses a fan-shaped strip adjustment structure for stamping dies. The adjustment rod 1 is installed in the lower pad of the lower template of the stamping die. By setting a guide groove in the lower pad, the adjustment rod 1 can be freely slid in the horizontal direction and can be prevented from deviating during movement. The pressing insert 7 can be installed in the stripper plate of the stamping die by bolts or other fasteners. Its position corresponds to the adjustment block 3 on the top surface of the fan-shaped adjustment part 2, so as to ensure that it can cooperate with the adjustment block 3 during the stamping process and apply appropriate extrusion force to the fan-shaped strip.

[0040] Understandably, the strip is placed in a floating state on the lower die plate of the stamping die. A strip guiding device, such as a guide groove or guide plate, can be set on the lower die plate to guide the conveying direction of the strip and ensure that the strip can accurately enter the stamping area during the stamping process. At the same time, a strip positioning device, such as a positioning pin or positioning needle, is installed on the lower die plate to position the strip at its initial position and prevent the strip from shifting during the stamping process.

[0041] In this invention, before the stamping die closes, based on the bending direction of the strip, if the strip bends in an arc along the positive Y-axis, that is... Figure 5 The outer fan-shaped material strip 9, at this time, the adjusting rod 1 can move along the negative Y-axis, so that the fan-shaped adjusting part 2 away from the other end of the adjusting rod 1 moves along the positive Z-axis, and the fan-shaped adjusting part 2 near the other end of the adjusting rod 1 moves along the negative Z-axis, until the top surface of the fan-shaped adjusting part 2 away from the other end of the adjusting rod 1 is at the same height as the top surface of the upper template. At this time, the adjusting block 3 on it protrudes from the top surface of the upper template and squeezes the material strip. When the mold is closed, it cooperates with the pressure insert 7 to correct the fan-shaped deformation of the material strip to achieve the product dimensional accuracy requirements. Conversely, before the stamping die is closed, according to the fan-shaped direction of the material strip, if the material strip bends in an arc along the negative Y-axis, that is, as Figure 6 The inner fan-shaped material strip 8 is in place. At this time, the adjusting rod 1 can move along the positive Y-axis, so that the fan-shaped adjusting part 2 near the other end of the adjusting rod 1 moves along the positive Z-axis, and the fan-shaped adjusting part 2 away from the other end of the adjusting rod 1 moves along the negative Z-axis until the top surface of the fan-shaped adjusting part 2 near the other end of the adjusting rod 1 is at the same height as the top surface of the upper template. At this time, the adjusting block 3 on it protrudes from the top surface of the upper template to squeeze the material strip. When the mold is closed, it cooperates with the pressing insert 7 to correct the fan-shaped deformation of the material strip in order to achieve the product dimensional accuracy requirements.

[0042] In practical use, during the stamping process, the pressing insert 7 moves downward under the drive of the stamping die closing and contacts the material strip. Under the combined action of the adjusting block 3 on one of the fan-shaped adjusting parts 2, it squeezes the material strip to create a groove 11 on the material strip, which promotes material flow and corrects the fan-shaped deformation of the material strip to achieve the product dimensional accuracy requirements.

[0043] Preferably, the fan-shaped adjusting part 2 includes a horizontal portion 22 and a vertical portion 23 arranged in an L-shape, and the adjusting block 3 is disposed on the top surface of the vertical portion 23. The L-shaped structure divides the functional area of ​​the fan-shaped adjusting part 2, and the horizontal portion 22 and the vertical portion 23 can each undertake different functions or roles. For example, the horizontal portion 22 can be used for connection with other components, positioning, or to provide a certain support, while the vertical portion 23 serves as the mounting carrier for the adjusting block 3, which helps to improve the functionality and reliability of the fan-shaped adjusting part 2.

[0044] Furthermore, a spring 4 is provided on the top surface of the horizontal portion 22 of the sector-shaped adjusting part 2. When the L-shaped sector-shaped adjusting part 2 is subjected to an external force and moves upward, the spring 4 will be compressed, which can play a buffering role. Moreover, the elastic characteristics of the spring 4 enable it to provide a stable force, which helps to maintain the stability of the L-shaped sector-shaped adjusting part 2 during the upward movement.

[0045] Furthermore, the stamping die fan-shaped strip adjustment structure also includes a pressure plate 5 fixed in the lower template. The pressure plate 5 is connected to the end of the spring 4 away from the horizontal part 22. The pressure plate 5, fixed in the lower template, provides a connection support point for the spring 4. When the spring 4 is installed between the top surface of the horizontal part 22 and the pressure plate 5, the pressure plate 5 remains in the correct installation position when the L-shaped fan-shaped adjustment part 2 moves upward to compress the spring 4, without any displacement or detachment. This ensures the buffering and stabilizing function of the spring 4.

[0046] Furthermore, when maintenance or replacement of spring 4 is required, it is more convenient to remove spring 4 for inspection, repair or replacement by disassembling the connection between pressure plate 5 and lower template, without having to disassemble the entire stamping die fan-shaped strip adjustment structure on a large scale.

[0047] Preferably, the other end of the adjusting rod 1 is provided with an adjusting mechanism 6. The adjusting mechanism 6 includes an adjusting rod base 61 fixed to the top of the lower mold base and an adjusting screw 62 rotatably disposed on the adjusting rod base 61. The adjusting screw 62 is configured to drive the adjusting rod 1 to move laterally by rotation.

[0048] The design of adjustment mechanism 6 is simple and straightforward, easy to maintain and adjust, which can reduce mold downtime and improve the overall operating efficiency of the production line.

[0049] The design of the adjusting screw 62 and the adjusting rod base 61 makes the position adjustment of the adjusting rod 1 more precise and stable, ensuring repeatability and reliability in the adjustment process.

[0050] In some embodiments, such as Figure 3 As shown, the cross-section of the adjusting block 3 is set as an isosceles trapezoid. The shape of the isosceles trapezoid allows the force to be distributed more evenly across the entire cross-section when the adjusting block 3 is subjected to external forces. Compared with shapes such as rectangles, the isosceles trapezoid provides better support and resistance to deformation when subjected to lateral forces.

[0051] Furthermore, the adjusting block 3 is detachably connected to the fan-shaped adjusting part 2. It is understood that the adjusting block 3 can be made of a material with higher hardness than the main body of the fan-shaped adjusting part 2. The adjusting block 3 in this invention can be designed to be integrally formed with the main body of the fan-shaped adjusting part 2, or it can be designed to be independently replaceable. This allows for the extension of the service life of the fan-shaped adjusting part 2 by replacing only the adjusting block 3 instead of the entire fan-shaped adjusting part 2.

[0052] In some embodiments, in order to reduce the movement resistance of the fan-shaped adjustment part 2, the first inclined surface 12, the second inclined surface 13 and the third inclined surface 21 are all set as polished surfaces.

[0053] In addition, because the smooth polished surface does not easily attract dust, oil and other impurities, it can help reduce wear on parts caused by increased friction due to dirt.

[0054] The second aspect of this utility model provides a stamping die, which includes a stamping die assembly and the aforementioned stamping die fan-shaped strip adjustment structure.

[0055] Understandably, the stamping die with the aforementioned fan-shaped strip adjustment structure solves the problem of not needing to replace adjustment parts. Instead, the corresponding fan-shaped adjustment parts can be directly adjusted on the stamping die according to the type of fan-shaped deformation of the strip. This solves the problem of low production uptime of high-speed presses, reduces the disassembly and assembly of die parts, and improves production efficiency.

[0056] The stamping die assembly consists of, from top to bottom, an upper cover plate, an upper die base, an upper backing plate, an upper clamping plate, a stripper backing plate, a stripper plate, a lower die plate, a lower backing plate, and a lower die base. The aforementioned stamping die fan-shaped strip adjustment structure is located in the lower backing plate and the lower die plate.

[0057] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
