Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a stamping die that facilitates the replacement of forming parts. Background Technology
[0002] In the hardware processing industry, stamping, as a highly efficient and low-cost metal forming technology, is widely used in the mass production of various hardware products such as automotive parts, electronic components, and home appliance accessories. Whether it's a simple washer or nut, or a complex automotive body panel, the forming process often relies on the precise fit of the stamping die. The rationality, stability, and adaptability of the die's structure directly determine the processing accuracy, production efficiency, and product qualification rate of the hardware parts. Therefore, the research and optimization of high-performance stamping dies has always been one of the core directions of technological innovation in the hardware processing field.
[0003] As hardware products develop towards higher precision, complexity, and multiple specifications, the market places higher demands on the performance of stamping dies. Traditional stamping dies often face the following problems when processing small and medium-sized hardware parts (such as connector terminals and miniature gear blanks): On the one hand, most dies have simple positioning structures, relying solely on the edge of the die base or a single guide post for positioning. During stamping, the hardware workpiece is prone to displacement due to uneven force, leading to dimensional deviations and excessive edge burrs in the processed workpiece. Especially for thin metal workpieces, wrinkles and deformation may even occur, severely affecting product quality. On the other hand, the forming components of traditional dies are mostly fixed to the die base by welding or integrated casting. When processing hardware parts of different specifications, the entire die set must be replaced, increasing equipment investment costs and extending production changeover time, making it difficult to meet the needs of multi-variety, small-batch hardware processing.
[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 In this embodiment of the utility model, a stamping die that facilitates the replacement of forming components is provided. The die includes an upper die base 1 and a lower die base 2 that are connected to each other. The upper die base 1 is located above the lower die base 2, and the two can achieve precise docking and cooperation during the stamping operation.
[0019] A stamping base 3 is mounted on the top of the lower die base 2. A first side plate 4 and a second side plate 5 are respectively provided on both sides of the top of the stamping base 3. The first side plate 4 and the second side plate 5 are arranged opposite each other, and a top plate 6 is mounted on the top of both of them. A channel 7 is formed between the stamping base 3, the first side plate 4, the second side plate 5 and the top plate 6. The channel 7 allows the workpiece to be processed to pass through, so as to realize the conveying of the workpiece during continuous stamping.
[0020] A punch head 8 is mounted on the bottom of the upper die base 1. The punch head 8 is detachably connected to the upper die base 1 via a second locking member 19, which can be a screw or other connecting component. When processing workpieces of different shapes or sizes, the punch head 8 of the corresponding specification can be replaced by disassembling the second locking member 19 to adapt to different stamping requirements. A punching groove 9 is provided on the stamping base 3. The position of the punching groove 9 corresponds to that of the punch head 8 and is used to accommodate the punch head 8 during stamping. A punching opening 10 is provided on the top plate 6. The size of the punching opening 10 is adapted to the punch head 8. When performing stamping operations, the punch head 8 can pass through the punching opening 10 and enter the punching groove 9 to perform stamping processing on the workpiece located in the channel 7.
[0021] The opposite sides of the first side plate 4 and the second side plate 5 both extend inward toward the channel 7 to form limiting edges 11. These limiting edges 11 are used to limit the workpiece passing through the channel 7, preventing lateral displacement during conveying or stamping and ensuring the workpiece is accurately positioned for stamping. When the width of the workpiece changes, the first side plate 4 and the second side plate 5 of corresponding specifications can be replaced to match the spacing between the limiting edges 11 and the workpiece width, ensuring effective limiting for workpieces of different widths. There is a gap between the limiting edges 11 and the stamping slot 9, which can be set according to the workpiece thickness, ensuring both limiting effect and preventing interference from the limiting edges 11 on the movement of the stamping head 8.
[0022] The top plate 6, the first side plate 4, the second side plate 5, and the stamping base 3 are all detachably connected to the lower die base 2 via the first locking member 18. Specifically, the stamping base 3 includes an upper base 12 and a lower base 13. The lower base 13 has a fitting groove 14 along its top end, and the upper base 12 extends along its bottom end to form a fitting part 15. The shape and size of the fitting part 15 are adapted to the fitting groove 14, and the two can be mated together. The fitting structure can improve the stability and accuracy of the connection between the upper base 12 and the lower base 13. The upper base 12 has the aforementioned stamping through groove 9. When the lower base 13 remains universal, the upper base 12 can be replaced according to the size and specifications of the workpiece to obtain a suitable stamping through groove 9, ensuring that the stamping head 8 can accurately process the workpiece. Both the lower base 13 and the lower die base 2 have waste discharge ports, which are coaxially corresponding to the stamping through groove 9 and are used to discharge the waste generated during the stamping process.
[0023] Both sides of the lower base 13 and the upper base 12 are formed as connecting ends 16, with a first through hole on the connecting end 16. The lower mold base 2 has a threaded groove, which is coaxially corresponding to the first through hole. The top plate 6, the first side plate 4, and the second side plate 5 are each provided with a second through hole 17, which is also coaxially corresponding to the first through hole. The first locking member 18 is a bolt, whose threaded end passes through the second through hole 17 on the top plate 6, the first side plate 4 or the second side plate 5, and the first through hole on the connecting end 16 of the stamping base 3, and then screws into the threaded groove on the lower mold base 2, thereby fixing the top plate 6, the first side plate 4, the second side plate 5, and the stamping base 3 together on the lower mold base 2. When it is necessary to replace the upper base 12, the first side plate 4, or the second side plate 5 of different specifications, the corresponding parts can be removed simply by loosening the first locking member 18, which is convenient. The top plate 6 can remain universal in most cases and is only replaced when the workpiece specifications change significantly, causing the stamping opening 10 to be mismatched, in order to improve the versatility of the mold and reduce replacement costs.
[0024] The top of the first side plate 4 and the second side plate 5 are respectively provided with protruding posts 20, and the bottom of the top plate 6 is provided with a slot. The position and size of the slot match the protruding posts 20. When the top plate 6 is installed, the protruding posts 20 are inserted into the slots, which can play a role in pre-positioning the top plate 6, making it easier to fix it later by the first locking member 18, and improving the stability of the connection between the top plate 6 and the side plate.
[0025] In summary, this stamping die, through the detachably connected stamping head 8, first side plate 4, second side plate 5, and upper base 12, allows for flexible replacement of corresponding components to adapt to processing requirements based on workpieces of different sizes. Meanwhile, the lower base 13 and top plate 6 are versatile across multiple scenarios, reducing component replacement costs and changeover time. Combined with the limiting edge 11, it precisely limits the workpiece, preventing offset. Furthermore, the stamping through groove 9 and waste discharge port work together to ensure smooth stamping and waste removal. Overall, it improves the die's versatility, processing accuracy, and ease of operation, adapting to the diverse production needs of hardware processing.
[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
