Description

Technical Field

[0001] This invention belongs to the field of metal stamping technology, specifically relating to a tooling and processing method for processing miniature wire clip parts. Background Technology

[0002] Miniature wire clips are accessories used to secure wires, cables, components, etc., serving functions such as fastening and connecting. They are characterized by their small size, light weight, usability in confined spaces, easy installation, and reusability. With the advancement of technology, miniature wire clips have found wide applications, including: electronics (mobile phones, tablets, cameras, etc.); communications (fiber optic cables, network cables, etc.); automotive (secured components and cables within vehicles); and industrial applications (cables for industrial machinery and equipment, etc.).

[0003] The miniature wire clip part is shown in Figure 1.

[0004] It includes an outer shape L1 / L2 / 4-R1 / L5 / L6 / L7 / 0.5, a 90° bend, and a through hole 4-φD. This miniature wire clip part is 0.5mm thick and made of aluminum alloy. The traditional processing method is to first cut the outer shape with wire cutting equipment, and then drill the 4-φD hole through the center of the milling machine.

[0005] Using this method of processing will result in the following problems:

[0006] 1) Wire cutting shape: Because the material of the miniature wire clip is aluminum alloy, the surface roughness of the miniature wire clip after cutting is too large.

[0007] 2) During the wire cutting process, the aluminum chips generated by the workpiece will cause spark discharge, resulting in black spots on the surface of the workpiece after processing. These spots are difficult to remove and the appearance is hard to meet the standards.

[0008] 3) These miniature wire clips are generally mass-produced parts. This production process can only process one piece at a time, resulting in extremely low efficiency, inconvenient loading and unloading, time-consuming and labor-intensive processing, and excessively high processing costs. Therefore, the following technical solution is proposed. Summary of the Invention

[0009] The technical problem solved by this invention is to provide a tooling and method for processing miniature wire clip parts, which adopts a one-time batch stamping forming method using customized tooling to solve the technical problems of poor processing quality, low processing efficiency and high cost of miniature wire clip parts.

[0010] The technical solution adopted in this invention is: a tooling for processing miniature wire clip parts, the tooling having a bending base, a stamping tooling, a front positioning plate, and a rear positioning plate.

[0011] The bending base is fixed to the stamping platform. The upper part of the bending base has a settling groove, and the lower part has a bending groove. The bending groove is adapted to the bending structure of the miniature wire clip parts. The bottom of the settling groove is used to lay multiple horizontally unfolded miniature wire clip parts side by side at one time.

[0012] The bottom of the stamping fixture has a 90° stamping structure, which is adapted to the bending groove. The 90° stamping structure is used to realize the one-time 90° stamping forming of multiple micro wire clip parts.

[0013] The front positioning plate is fastened to the front side of the bending base, and the rear positioning plate is fastened to the rear side of the bending base; the sinking grooves of the front positioning plate, rear positioning plate, and bending base are used to restrict the displacement of multiple miniature wire clip parts from all sides.

[0014] The stamping fixture is fitted into a closed cavity formed by the settling groove, the front positioning plate, and the rear positioning plate; a press or magnetic punch applies pressure to the upper surface of the stamping fixture, and the 90° stamping structure of the stamping fixture is used to achieve one-time bending and stamping forming of multiple parallel micro wire clip parts.

[0015] In the above technical solution, the preferred embodiment is as follows: the horizontal span of the settling groove is L1w, L1w = Lz, where Lz is the unfolded dimension of the miniature wire clip part, and the tolerance of L1w is L1w + 0.10 + 0.05; the horizontal span of the bending groove is L2w, the depth of the bending groove is L3w, the bottom end of the settling groove and the top end of the bending groove are transitioned by an R0.5 arc, and the bottom end of the bending groove is provided with an R1 arc; L3w = L6 - 0.5, L2w = L5 + 2 * 0.5, where 0.5 is the thickness of the miniature wire clip part, and the tolerances of L3w and L2w are both L3w + 0.05 0 and L2w + 0.05 0.

[0016] The width of the bent base is L8w, where L8w > n*L2, and n is an integer multiple.

[0017] The upper horizontal length of the stamping fixture is L1c, L1c = Lz, and L1c has a clearance fit with the bending base L1w. The tolerance of L1w is +0.10 +0.05, and the tolerance of L1c is +0.05 0. The horizontal length of the 90° stamping structure of the stamping fixture is L2c, and the depth is L3c. The top of the 90° stamping structure is transitioned by an R1 arc, and the bottom of the 90° stamping structure is transitioned by an R0.5 arc. The tolerance of L2c is 0 -0.05, and the tolerance of L3c is +0.05 0. The total thickness of the stamping fixture is L4c, L4c > L3w + L9w, where L3w is the bending groove depth and L9w is the settling groove depth. The upper width of the stamping fixture is L5c, L5c = L8w - L9q > n * L2, where L8w is the width of the stamping fixture, L9q is the height of the front positioning plate step, and n is an integer multiple.

[0018] The front positioning plate step dimensions L1q / L2q / L3q / L4q / 2-R1 / 2-R0.5 are matched with the gap of the bending base L3w / L2w / 2-R1 / 2-R0.5; the front positioning plate step thickness L9q=L8w-n*L2, where n is an integer multiple; the front positioning plate outer dimensions L6q / L8q are consistent with the bending base outer dimensions L6w / L7w.

[0019] The rear positioning plate has the same external dimensions L1h / L2h as the front positioning plate L6q / L8q and the bending base L6w / L7w.

[0020] In the above technical solution, the preferred embodiment is that the bending base, stamping fixture, front positioning plate, and rear positioning plate are made of steel, and the steel is heat-treated and aged steel.

[0021] In the above technical solution, further: the front and rear ends of the bending base are respectively provided with threaded holes, and the front positioning plate and the rear positioning plate are fastened together with the bending base using fasteners.

[0022] This invention also claims protection for a method for processing a miniature wire clip component, the method using any of the tooling options described above, the method comprising the following steps:

[0023] S1. Fix the bending base to the stamping platform.

[0024] S2. Unfold and lay the multiple micro wire clip parts, which have been laser-cut, flat at the bottom of the settling groove.

[0025] S3. Secure the front and rear positioning plates to the vertical end face of the miniature wire clip part, and use fasteners to firmly connect the front and rear positioning plates to the bending base to achieve end face positioning of the miniature wire clip part.

[0026] S4. Insert the stamping fixture into the bending base, apply pressure to the stamping fixture through a press or magnetic punch, and achieve one-time bending and stamping forming of multiple parallel micro wire clip parts through the 90° stamping structure of the stamping fixture.

[0027] S5. Remove the stamping fixture, remove the front or rear positioning plate, take out the formed micro wire clip parts, load the next batch of micro wire clip parts, reinstall the front or rear positioning plate, and repeat step S4; repeat this process to achieve batch stamping and forming of micro wire clip parts.

[0028] Advantages of this invention compared to existing technologies: This invention enables batch processing of micro wire clip parts, and the tooling for stamping micro wire clip parts is reusable. In addition, the tooling structure is simple and easy to assemble, resulting in micro wire clip parts with good processability and reliable quality, effectively improving the processing efficiency of micro wire clip parts.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to Figures 1-10. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] A tooling for processing miniature wire clip parts, the tooling having a bending base 1, a stamping tool 2, a front positioning plate 3, and a rear positioning plate 4.

[0048] As shown in Figure 1, the miniature wire clip component 5 comprises an outer shape L1 / L2 / 4-R1 / L5 / L6 / L7 / 0.5, a 90° bend, and a through hole 4-φD. The miniature wire clip component 5 has a thickness of 0.5mm and is made of aluminum alloy. Specifically, the miniature wire clip component 5 has a length L1, a width L2, and a thickness of 0.5mm. The horizontal length of the bend structure 501 is L5, the total height of the bend structure 501 is L6, and the height of the bend structure 501 is L7.

[0049] (like Figure 5 As shown, the bending base 1 is fixed to the stamping platform 7. The upper part of the bending base 1 has a settling groove 102, and the lower part has a bending groove 101. The bending groove 101 is adapted to the bending structure 501 of the miniature wire clip part 5. The bottom of the settling groove 102 is used to lay multiple horizontally unfolded miniature wire clip parts 5 side-by-side (e.g., ...). Figure 6 (As shown).

[0050] (like Figure 8 , Figure 10 As shown, the stamping fixture 2 has a 90° stamping structure 201 at its bottom. The 90° stamping structure 201 is adapted to the bending groove 101, and the 90° stamping structure 201 is used to realize the one-time 90° stamping forming of multiple micro wire clip parts 5 (e.g., Figure 10 (As shown). The bending groove 101 is adapted to the bending structure 501 of the miniature wire clip part 5, and the 90° stamping structure 201 of the stamping fixture 2 is also adapted to the bending groove 101. This precise adaptation relationship enables the part to accurately complete the 90° bend according to the design requirements during the stamping process, ensuring the dimensional accuracy and quality stability of the product.

[0051] (like Figure 7As shown, the front positioning plate 3 is fastened to the front side of the bending base 1, and the rear positioning plate 4 is fastened to the rear side of the bending base 1. The settling groove 102 of the front positioning plate 3, the rear positioning plate 4, and the bending base 1 is used to restrict the displacement of multiple micro wire clip parts 5 from all sides. In this invention, the front positioning plate 3 is fastened to the front side of the bending base 1, and the rear positioning plate 4 is fastened to the rear side of the bending base 1, together with the settling groove 102 of the bending base 1, restricting the displacement of multiple micro wire clip parts 5 from all sides. This positioning method ensures that each part is in an accurate position before stamping, providing a guarantee for subsequent precise stamping, effectively avoiding processing errors caused by part position deviation, and improving the product qualification rate.

[0052] (like Figure 9 As shown, the stamping fixture 2 is adapted to be incorporated into the surrounding closed cavity formed by the settling groove 102, the front positioning plate 3, and the rear positioning plate 4; a press or magnetic punch applies pressure to the upper surface of the stamping fixture 2, and the 90° stamping structure 201 of the stamping fixture 2 is used to realize the one-time bending and stamping forming of multiple parallel micro wire clip parts 5.

[0053] The stamping fixture 2 of this invention can be adapted to fit into the enclosed cavity formed by the settling groove 102, the front positioning plate 3, and the rear positioning plate 4. This structural design makes the entire fixture system more compact and reasonable, with each component cooperating and working together to fully utilize the function of each component and improve the overall performance and reliability of the fixture.

[0054] It should be noted that multiple horizontally unfolded micro wire clip parts 5 can be laid side by side at the bottom of the settling groove 102. Combined with the 90° stamping structure 201 at the bottom of the stamping fixture 2, which adapts to the bending groove, multiple micro wire clip parts 5 can be stamped into shape at a single 90° angle. This design significantly improves production efficiency, reducing processing time and labor costs compared to processing individual parts sequentially, making it suitable for large-scale production. The entire processing is simple to operate, requiring no complex steps or professional skills, reducing the technical requirements for operators and improving the convenience and operability of production. This fixture can be used with a press or magnetic punch, adapting to different production equipment and environments. Enterprises can flexibly choose a suitable power source to drive the stamping fixture for processing based on their own production conditions and equipment, improving the versatility and applicability of the fixture.

[0055] In the above embodiments, preferably (as shown in Figure 2), the horizontal span of the settling groove 102 is L1w, where L1w = Lz, Lz is the unfolded dimension of the micro wire clip part 5, and the tolerance of L1w is L1w + 0.10 + 0.05. This design of the present invention ensures that the part can be smoothly placed into the settling groove 102 without causing the part to wobble freely in the groove due to excessive gaps, thus achieving precise positioning of the part and providing a foundation for the accuracy of subsequent processing. The suitable horizontal span and tolerance range of the settling groove 102 allow multiple parts to be neatly and stably laid side by side in the settling groove 102, avoiding mutual squeezing or misalignment between parts, which is beneficial for the subsequent stamping fixture to process multiple parts simultaneously, improving processing efficiency and product quality consistency.

[0056] The horizontal span of the bending groove 101 is L2w, and the depth of the bending groove 101 is L3w. The bottom end of the settling groove 102 and the top end of the bending groove 101 are transitioned by an R0.5 arc. The bottom end of the bending groove 101 has an R1 arc. L3w = L6 - 0.5, L2w = L5 + 2 * 0.5, where 0.5 is the thickness of the micro wire clip part 5. The tolerances for L3w and L2w are L3w + 0.05 0 and L2w + 0.05 0, respectively. This precise depth design of the bending groove 101 ensures that the part reaches the required bending angle and size during the stamping and bending process. At the same time, tolerance control ensures the consistency of the bending depth of each part, improving the product's accuracy and quality stability. This design takes into account the part's thickness, providing suitable space for bending, allowing the part to deform smoothly during bending without causing bending difficulties or part damage due to insufficient space, while also ensuring the dimensional accuracy of the part after bending. Furthermore, the bottom end of the settling groove 102 and the top end of the bending groove 101 are connected by an R0.5 arc, and the bottom end of the bending groove 101 is provided with an R1 arc. These arc designs can effectively reduce the stress concentration phenomenon generated by the parts during the bending process, avoid the parts from cracking or breaking due to stress concentration, improve the strength and reliability of the parts, and extend the service life of the parts.

[0057] Furthermore, the bending base 1 has a width of L8w, where L8w > n*L2, and n is an integer multiple. This design allows for the simultaneous processing of multiple parts, enabling mass production. Enterprises can flexibly adjust the value of n according to production needs, improving production efficiency and reducing production costs. In addition, the wider bending base 1 increases the contact area between the tooling and the stamping platform 7, improving the stability and vibration resistance of the tooling during processing. During stamping, the tooling is less prone to shaking or displacement, ensuring processing accuracy and consistency and reducing the scrap rate.

[0058] (As shown in Figure 3) The upper horizontal length of the stamping fixture 2 is L1c, where L1c = Lz, and Lz is the unfolded dimension of the miniature wire clip part 5. L1c and the bending base 1 L1w are in clearance fit, with L1w tolerance +0.10 +0.05 and L1c tolerance +0.05. This design allows the stamping fixture 2 to be smoothly installed when placed into the bending base 1, while also achieving precise positioning through the clearance fit. This avoids processing errors caused by fixture wobbling during stamping, ensuring processing stability and accuracy. The suitable tolerance range of the stamping fixture 2 ensures tightness and flexibility of the fit, preventing fixture misalignment due to excessive clearance and installation difficulties due to insufficient clearance, thus improving production efficiency and ease of operation. Since parts may experience dimensional fluctuations during production, the tolerance design of L1w and L1c provides a certain tolerance space for these dimensional changes, allowing the stamping fixture 1 to adapt to parts of different sizes within a certain range, improving the versatility and adaptability of the fixture.

[0059] The 90° stamping structure 201 of the stamping fixture 2 has a horizontal length of L2c and a depth of L3c. The top of the 90° stamping structure 201 transitions through an R1 arc, and the bottom of the 90° stamping structure 201 transitions through an R0.5 arc. The tolerance of L2c is 0 -0.05, and the tolerance of L3c is +0.05. The precise dimensional tolerance control of this invention ensures accurate matching between the 90° stamping structure 201 and the bending part of the part, enabling accurate 90° bending of the part according to design requirements, thus guaranteeing the dimensional accuracy and quality stability of the product. The appropriate tolerance range ensures that each part is subjected to uniform force during the stamping process, avoiding problems such as inconsistent bending angles and inaccurate bending dimensions caused by dimensional deviations, thereby improving the product qualification rate. The top of the 90° stamping structure 201 is transitioned by an R1 arc, and the bottom is transitioned by an R0.5 arc. These arc designs effectively reduce stress concentration during bending, preventing cracks or fractures caused by stress concentration and improving the strength and reliability of the parts. Simultaneously, the arc transitions reduce friction and wear between the stamping structure and the parts, extending the service life of the stamping fixture and lowering production costs.

[0060] The total thickness of the stamping fixture 2 is L4c, where L4c > L3w + L9w, L3w is the depth of the bending groove 101, and L9w is the depth of the settling groove 102. This design ensures that the stamping fixture 2 has sufficient stroke during the stamping process to complete the bending operation of the part, allowing the part to fully enter the bending groove 101 and reach the required bending depth, thus ensuring the integrity and accuracy of the processing. Sufficient thickness provides the stamping fixture 2 with good structural strength, enabling it to withstand the large pressure generated during the stamping process without deformation or damage, ensuring the stability and reliability of the stamping fixture, thereby ensuring processing quality.

[0061] The upper width of stamping fixture 2 is L5c, where L5c = L8w - L9q > n * L2, L8w is the width of stamping fixture 2, L9q is the step height of the front positioning plate 3, and n is an integer multiple. This design allows stamping fixture 2 to simultaneously stamp multiple parts, enabling mass production, significantly improving production efficiency, and reducing production costs. Enterprises can flexibly adjust the value of n according to production needs to adapt to different scales of production tasks, improving the flexibility and versatility of the fixture.

[0062] As shown in Figures 4(a) and 4(b):

[0063] The step dimensions L1q / L2q / L3q / L4q / 2-R1 / 2-R0.5 of the front positioning plate 3 are matched with the clearance of L3w / L2w / 2-R1 / 2-R0.5 of the bending base 1. This design allows the front positioning plate 3 to be precisely installed on the bending base 1. The clearance fit ensures both smooth installation and accurate positioning, avoiding positioning deviations during processing. Simultaneously, the step structure of the front positioning plate 3 provides stable support, ensuring that the front positioning plate 3 will not wobble or shift during stamping, thus guaranteeing the accuracy and stability of part processing. The rounded transition at the step of the front positioning plate 3 effectively reduces stress concentration, extends the service life of the positioning plate, and reduces production costs. The step thickness of the front positioning plate 3 is L9q = L8w - n*L2, where n is an integer multiple. This design allows the front positioning plate 3 to match the width of the stamping fixture 2 and the dimensions of the parts, making it possible to batch process multiple parts. The appropriate step thickness of the front positioning plate 3 not only meets the needs of batch processing but also ensures sufficient structural strength. During the stamping process, the front positioning plate 3 needs to withstand a certain amount of pressure; sufficient thickness ensures that it will not deform or be damaged due to excessive pressure, thus guaranteeing the stability and reliability of the processing. The external dimensions L6q / L8q of the front positioning plate 3 are consistent with the external dimensions L6w / L7w of the bending base 1. This design allows the front positioning plate 3 to perfectly align with the bending base 1 during installation, reducing adjustment work during installation and improving installation efficiency and accuracy. Simultaneously, the consistent external dimensions facilitate overall tooling debugging and maintenance, reducing operational difficulty and cost. The consistent external dimensions of the front positioning plate 3 and the bending base 1 make the overall tooling look neater and more aesthetically pleasing, reflecting the standardization and professionalism of the design. Furthermore, this coordination also helps improve the user experience of the tooling, facilitating operation and management for operators.

[0064] As shown in Figures 4(c) and 4(d):

[0065] The rear positioning plate 4 has the same external dimensions (L1h / L2h) as the front positioning plate 3 (L6q / L8q) and the bending base 1 (L6w / L7w). This design ensures that the rear positioning plate 4 can be precisely aligned with the front positioning plate 3 and the bending base 1 during installation, forming a complete positioning system. By matching the external dimensions of the three components, parts can be accurately positioned from multiple directions, avoiding processing errors caused by inaccurate positioning and improving product quality and yield. The consistent external dimensions allow the rear positioning plate 4 to fit tightly with the front positioning plate 3 and the bending base 1, forming a stable overall structure. During stamping, this stable structure effectively resists external forces, reduces tooling vibration and deformation, and ensures smooth processing, thereby improving processing accuracy and efficiency. The consistent external dimensions facilitate standardized production and management of the tooling; tooling components from different batches can be interchanged, improving the tooling's versatility and interchangeability. This not only reduces production costs but also facilitates tooling maintenance and repair, increasing tooling lifespan and economic benefits.

[0066] In the above embodiments, preferably, the bending base 1, stamping fixture 2, front positioning plate 3, and rear positioning plate 4 are made of steel, specifically heat-treated and age-treated steel. Heat treatment can significantly improve the strength of steel by altering its internal microstructure, such as through martensitic transformation. Heat treatment also increases the hardness of the steel, making the fixture surface more wear-resistant. Although heat treatment improves the strength and hardness of the steel, a proper heat treatment process can also ensure that the steel retains a certain degree of toughness. During steel processing, such as forging, cutting, and welding, residual stress is generated. This residual stress can cause deformation of the fixture during use, affecting the machining accuracy of the parts. Aging treatment can release and eliminate the residual stress inside the steel, reducing the deformation of the fixture. After aging treatment, the dimensions of the fixture are more stable, maintaining the required accuracy over a long period, ensuring consistent dimensions of the processed miniature wire clip parts, and improving the product qualification rate. In the processing environment, temperature may change. Steel has a large coefficient of thermal expansion and contraction, and temperature changes can cause changes in the dimensions of the fixture, thus affecting machining accuracy. Steel that has undergone heat treatment and aging treatment has a more uniform and stable internal structure, reduced sensitivity to temperature changes, and can maintain dimensional stability within a certain temperature range, reducing processing errors caused by temperature variations. Heat treatment can adjust the hardness and toughness of steel, making it more suitable for machining. For some complex-shaped tooling components, such as the 90° stamping structure of stamping tooling, forming processing is required to meet design requirements. Heat treatment can improve the plasticity of steel, making it easier to deform during forming processing, reducing defects such as cracking, and improving forming quality. At the same time, aging treatment can eliminate residual stress generated during forming, further improving the dimensional accuracy and stability of tooling. Heat treatment and aging treatment improve the performance of steel in multiple ways, giving tooling higher strength, hardness, toughness, and dimensional stability. Due to the extended service life of tooling, the number of tooling replacements is reduced, correspondingly lowering the procurement and installation and commissioning costs of tooling. At the same time, dimensionally stable tooling reduces the scrap rate during processing, reducing the increased costs caused by scrap disposal and rework, further improving the economic benefits of enterprises.

[0067] In the above embodiments, further: (e.g.) Figure 7As shown, the bending base 1 has threaded holes on its front and rear end faces. Fasteners 6 are used to secure the front positioning plate 3 and rear positioning plate 4 to the bending base 1 as a single unit. The use of threaded holes and fasteners 6 provides a simple and quick way to install and remove the front and rear positioning plates from the bending base 1. Connecting using threaded holes and fasteners 6 does not require highly skilled operators or special training. By providing threaded holes on the front and rear end faces of the bending base 1, the installation positions of the front and rear positioning plates can be accurately determined. Fasteners 6 tightly connect the front and rear positioning plates to the bending base 1, forming a stable integrated structure. When a component of the tooling is damaged or worn, the detachable connection allows operators to easily remove the damaged component for repair or replacement. Because the front and rear positioning plates can be easily replaced and adjusted using fasteners, this tooling is compatible with the processing of various sizes and shapes of miniature wire clip parts.

[0068] This invention also claims a method for processing a miniature wire clip component, the method using any of the tooling claims described above, the method comprising the following steps:

[0069] (like Figure 5 (As shown) S1, fix the bending base 1 to the stamping platform 7.

[0070] (like Figure 6 (As shown) S2, unfold and lay the multiple laser-cut micro-wire clip parts 5 flat at the bottom of the settling groove 102. Laser cutting allows for precise cutting according to the contours of the parts, reducing material waste. At the same time, batch processing makes the concentrated use of materials more rational, further improving material utilization and reducing raw material costs.

[0071] (like Figure 7 (As shown) S3, firmly attach the front positioning plate 3 and the rear positioning plate 4 to the vertical end face of the miniature wire clip part 5, and use fasteners 6 to fasten the front positioning plate 3 and the rear positioning plate 4 to the bending base 1 as a whole to achieve end face positioning of the miniature wire clip part 5. This achieves precise positioning of the part.

[0072] (like Figure 8 , Figure 9 (As shown) S4. Insert the stamping fixture 2 into the bending base 1, and apply pressure to the stamping fixture 2 using a press or magnetic punch (e.g.) Figure 10 As shown, multiple parallel micro wire clip parts 5 are formed by a single bending and stamping process using the 90° stamping structure 201 of the stamping fixture 2. This step standardizes the forming process of the parts.

[0073] S5. Remove the stamping fixture 2, remove the front positioning plate 3 or the rear positioning plate 4, take out the formed micro wire clip part 5, load the next batch of micro wire clip parts 5, reinstall the front positioning plate 3 or the rear positioning plate 4, and repeat step S4; repeat this process to achieve batch stamping and forming of micro wire clip parts 5.

[0074] It should be noted that step S5 describes the process of removing stamping fixture 2, removing the positioning plate, taking out the formed part, loading the new part, reinstalling the positioning plate, and then repeating the stamping steps. The entire mold changing and reloading process is relatively simple and quick, reducing downtime in the production process, enabling the production line to operate more continuously, and further improving production efficiency.

[0075] In step S2, multiple laser-cut micro-wire clip parts are unfolded and laid flat at the bottom of the settling groove. In step S4, the 90° stamping structure of the stamping fixture achieves a single bending and stamping forming of multiple side-by-side parts. This batch processing method avoids the low efficiency of processing individual parts one by one, and can complete the forming of multiple parts in a single stamping operation, greatly shortening the production cycle, increasing the number of parts produced per unit time, and meeting the needs of large-scale production. Batch processing and simplified operation procedures reduce the manpower required in the production process.

[0076] The entire processing method of this invention has clear and explicit steps, making it easy for operators to understand and master. From fixing the bending base 1, laying the parts flat, positioning and installing, to stamping and part removal and material change, each step has corresponding illustrated explanations, making the operation more intuitive and simple, reducing the complexity and error rate of operation. During the processing, the design and use of the tooling fully consider safety factors. The tight connection between the front and rear positioning plates and the bending base 1, as well as the reasonable inclusion of the stamping tooling, ensure the stability of the parts and tooling during processing, avoiding safety accidents caused by parts flying out or tooling loosening. At the same time, operators only need to operate from a safe position, reducing contact with dangerous areas and improving the safety of the production process.

[0077] The tooling and method of this invention have a certain degree of versatility. By adjusting the position of the positioning plate and replacing the stamping tooling 2 with different specifications, it can adapt to the processing of micro wire clip parts 5 of different sizes and shapes. This eliminates the need for enterprises to design and manufacture special tooling for each part, reducing tooling development costs and inventory management difficulties, and improving the enterprise's production flexibility and market responsiveness.

[0078] Because the tooling structure of this invention is relatively simple and easy to operate, it is easier to implement process improvements and optimizations. For example, stamping parameters, positioning methods, etc., can be adjusted and optimized according to actual production conditions to further improve product quality and production efficiency without requiring large-scale modifications to the entire processing system.

[0079] As can be seen from the above description, the present invention can realize the batch processing of micro wire clip parts, and the tooling for stamping micro wire clip parts can be reused. In addition, the tooling structure is simple and easy to assemble, and the processed micro wire clip parts have good processability and reliable quality, effectively improving the processing efficiency of micro wire clip parts.
