Description

Technical Field

[0001] This invention belongs to the field of copper or copper-aluminum material stamping technology, specifically relating to a production process for copper or copper-aluminum transition power equipment output clamps, which is based on continuous precision stamping technology. Background Technology

[0002] In power system line connection and fixing scenarios, the equipment outlet clamp is a key clamping component. Its core function is to securely clamp the conductor terminals (bars) and ensure a low contact resistance and high stability electrical connection between conductors, directly affecting the safety and efficiency of power transmission. Existing outlet clamps generally adopt a two-part split structure design, which is not only cumbersome in manufacturing but also inconvenient in use. Therefore, it is necessary to develop an integrated outlet clamp to simplify the operation process.

[0003] However, the special structure of the integrated cable clamp places stringent requirements on the molding process, and traditional molding processes cannot produce products that meet the usage requirements. One method is casting. During casting, defects such as shrinkage porosity, air holes, and impurity inclusions are easily formed inside the product, leading to a decrease in conductivity and strength. The second method is forging, which can basically guarantee the electrical performance of the product, but it requires secondary precision machining after forming to achieve the assembly accuracy, resulting in problems such as low production efficiency, poor product consistency, and high energy consumption. Thirdly, there is the traditional stamping method. This process uses a composite mold to stamp all the holes and arc-shaped clamping grooves on the blank in one go, and then bends it into shape in one go to quickly obtain the wire clamp product. However, this process often causes the two arc-shaped clamping grooves to be misaligned and the bolt connection holes of the two clamping plates to be misaligned. This can lead to problems such as difficulty in inserting bolts, uneven clamping force of the two clamping plates, and uneven contact during use, resulting in high contact resistance and easy overheating.

[0004] In addition, the small size, light weight and spatial shape of the integrated cable clamp also limit the equipment compatibility of stamping and subsequent quality inspection, and there is a lack of automated implementation methods that can be learned from. Summary of the Invention

[0005] To address the technical problems mentioned above, this invention provides a manufacturing process for copper or copper-aluminum transition power equipment output clamps. This process is based on continuous precision stamping technology and can meet the requirements for manufacturing accuracy and efficiency.

[0006] The technical solution of the present invention is as follows: A manufacturing process for copper or copper-aluminum transition power equipment output clamps includes the following steps: Step 1: Prepare a rectangular copper or copper-aluminum transition blank according to the dimensions of the wire clamp product; Step 2: Use the punching and precision cutting composite module to simultaneously perform corner cutting, locking hole punching, and equipment assembly hole punching on the blank. At the same time, punch the center positioning line of the convex center at the corresponding two arc-shaped convex positions on the blank to obtain the first processed blank. Step 3: Based on the embossing center positioning line in Step 2, place the first-processed blank in the embossing mold, align the convex cavity of the embossing mold with the embossing center positioning line in Step 2, and simultaneously stamp to form two arc-shaped convex shapes to obtain the second-processed blank. Step 4: Using the pre-bending module, in the area of ​​the connecting bridge of the wire clamp corresponding to the second processed blank, simultaneously pre-bend the two wire clamps corresponding to the second processed blank to the first preset angle to obtain the third processed blank. Step 5: Using the bending forming module, simultaneously bend the two wire clamps corresponding to the third processing blank to the second preset angle, so that the two arc-shaped convex parts meet to form a circular channel, while maintaining the preset pressure holding time, to obtain the wire clamp product.

[0007] In the production process of the copper or copper-aluminum transition power equipment output clamp described above, in step 3, the ratio of the convex depth H2 of the arc-shaped convex to the diameter D satisfies: 0.1≤H2 / D≤0.3.

[0008] In the production process of copper or copper-aluminum transition power equipment output clamps as described above, the first preset angle in step 4 is 85°-89°, and the second preset angle in step 5 is 89.5°-90.5°.

[0009] Preferably, the first preset angle in step 4 is 85°, and the second preset angle in step 5 is 90°.

[0010] In the production process of copper or copper-aluminum transition power equipment outlet clamps as described above, the temperature of the embossing die is controlled between 20℃ and 120℃ before performing step 3.

[0011] Preferably, the temperature of the embossing die is 100℃-120℃.

[0012] As one implementation method, the punching die includes an upper punch and a lower die, and the bottom of the cavity of the lower die is provided with an vent hole.

[0013] As one implementation method, the punching and precision cutting composite module includes an inner punch that corresponds to each locking hole and equipment assembly hole. The punch cutting edge of the inner punch is provided with a guide cone angle, and the single-sided punching gap of the inner punch is 1% of the thickness of the wire clamp blank.

[0014] The production process of copper or copper-aluminum transition power equipment outlet clamps as described above also includes step 6, which involves inspecting the outlet clamp products, removing defective products, and obtaining qualified products.

[0015] Preferably, steps 2 to 5 are completed continuously and automatically on a multi-station precision stamping die, and the blanks between each step are automatically transferred by a robotic arm.

[0016] The beneficial effects of this invention are as follows: by using a stamping process to prepare an integrated U-shaped wire clamp, the internal defects such as shrinkage porosity, air holes, and impurity inclusions that are easily generated when preparing an integrated wire clamp by casting are first avoided. The full stamping process allows the copper fibers to be continuously distributed along the product contour, ensuring the conductivity and mechanical strength of the product. At the same time, the product is formed in one step through continuous precision stamping, eliminating the need for secondary precision machining as required by forging. This solves the problems of low production efficiency, poor product consistency, and high energy consumption of forging. Most importantly, the innovative design of chamfering, punching positioning lines, and embossing is achieved through a process that integrates chamfering, punching, positioning lines, and embossing. The stamping process sequence, from step-by-step bending to pressure holding and shaping, replaces the traditional one-step punching and bending process. This effectively avoids the core problems of misalignment of the arc-shaped protrusions of the two clamping plates and misalignment of the locking holes, improving forming accuracy. Under temperature-controlled and exhaust conditions, the punching-forging composite mechanism is used for protrusion. This process allows the material in this area to fully plastically flow, making the structure denser and ensuring forming accuracy. From the overall process perspective, the forming accuracy of the wire clamp is guaranteed, eliminating problems such as difficulty in bolt insertion, uneven clamping force, and uneven contact during subsequent use. This also avoids the overheating phenomenon caused by excessive contact resistance. Furthermore, the stamping process of this invention is progressively advanced, adapting to the plastic processing characteristics of copper or copper-aluminum transition materials. Combined with an automated multi-station production method, it not only ensures extremely high product consistency and stability but also significantly improves the yield rate. At the same time, the process is compact and efficient, resulting in excellent product forming consistency, which is suitable for the industrial needs of large-scale mass production. With subsequent automated quality inspection methods, it can stably produce and screen integrated U-shaped wire clamps that meet structural and precision requirements, balancing product forming quality and production efficiency.

[0019] Example 1 This embodiment provides a manufacturing process for copper or copper-aluminum transition power equipment output clamps. This process is based on continuous precision stamping technology and can meet the requirements of manufacturing accuracy and efficiency.

[0020] Before introducing the above-mentioned continuous precision stamping process, we will first combine... Figure 2 The specific structure of the integrated cable clamp to be manufactured in this embodiment will be described below: The integrated cable clamp includes a first cable clamp 1 and a second cable clamp 2 arranged opposite to each other, and a connecting bridge 3 that integrally connects one end of the first cable clamp 1 and the second cable clamp 2. The middle of the opposite side of the first cable clamp 1 and the second cable clamp 2 are provided with arc-shaped protrusions 4. The two arc-shaped protrusions 4 are joined together to form a circular channel 5 for conductors to pass through. The two cable clamps are provided with through locking holes 6 on both sides corresponding to each arc-shaped protrusion 4. The end of the first cable clamp 1 away from the connecting bridge 3 extends in the direction away from the second cable clamp 2, and the extended part is provided with equipment mounting holes 7.

[0021] Based on the aforementioned integrated cable clamp, the manufacturing process for the copper or copper-aluminum transition power equipment cable clamp provided in this embodiment is as follows: Figure 1 As shown, the specific steps are as follows: Step 1: According to the dimensions of the cable clamp product, cut a rectangular copper or copper-aluminum transition blank that matches the dimensions of the cable clamp product. The blank should be made of T2 copper or copper material with a purity of ≥99.90% (e.g., Figure 2 The cable clamp shown (excluding the part where the equipment assembly hole 7 is located on the second clamp plate 2) is made of T2 copper with a purity of ≥99.90% and is a copper-aluminum transition material. The thickness of the billet is determined according to the required current carrying capacity of the cable clamp of the copper / copper-aluminum transition power equipment, and the thickness is usually 12mm-35mm.

[0022] Step 2: Feed the rectangular blank into the first station of the multi-station precision stamping die, and simultaneously perform corner cutting, locking hole 6 punching and equipment assembly hole 7 punching on the blank. At the same time, at the preset forming positions of the two arc-shaped protrusions 4 on the blank, the center positioning line of the protrusion is formed by simultaneous stamping, and the first processed blank is obtained.

[0023] The punching and precision cutting composite module includes an upper module and a lower module. The lower side of the upper module is equipped with an inner punch that corresponds to the preset positions of each locking hole 6 and equipment assembly hole 7, an outer cutting edge for contour finishing, and a center positioning line protrusion that corresponds to the preset forming positions of the two arc-shaped protrusions 4.

[0024] Each inner punch has a carbide cutting edge, and each inner punch has a guide cone at the cutting edge end. The lower die has a cavity corresponding to each inner punch, and the single-sided punching gap between the inner punch and the cavity is 1% of the thickness of the blank. After punching, the hole wall is chamfered and deburred.

[0025] Step 3: First, control the temperature of the second station embossing die of the multi-station precision stamping die within the range of 20℃-120℃. In this embodiment, the temperature of the embossing die is controlled at 100℃-120℃. Then, the first-processed blank is automatically transferred to the embossing die by a robot. Based on the embossing center positioning line in Step 2, the convex cavity of the embossing die is precisely aligned with the embossing center positioning line on the first-processed blank. Through synchronous stamping by the embossing die, two arc-shaped convex 4 are formed on the first-processed blank to obtain the second-processed blank.

[0026] The punching die consists of a matching upper punch and a lower die. The bottom of the cavity of the lower die has an exhaust hole. The arc-shaped punch 4 formed by stamping has a punching depth H2 and its own arc diameter D that strictly meet the design requirement of 0.1≤H2 / D≤0.3. This ratio ensures that the arc-shaped punch 4 has sufficient coverage without reducing the structural strength of the wire clamp product.

[0027] Step 4: The second-processed blank is transferred to the third station pre-bending module of the multi-station precision stamping die by a robotic arm. At the connecting bridge 3 position corresponding to the wire clamp of the second-processed blank, the two corresponding wire clamp parts on the second-processed blank are simultaneously pre-bent to the first preset angle to obtain the third-processed blank.

[0028] One example is that the pre-bending module has a V-shaped or arc-shaped forming cavity for forming a pre-bending angle.

[0029] The first preset angle is in the range of 85°-89°, and preferably 85°.

[0030] Step 5: The third-processed blank is transferred to the bending and forming module by a robotic arm, and the two wire clamp parts on the third-processed blank are simultaneously bent to the second preset angle.

[0031] One example is that the bending forming module has a closed cavity that matches the final shape of the wire clamp. The second preset angle is in the range of 89.5°-90.5°, preferably 90°, so that the two arc-shaped protrusions 4 are precisely aligned to form a circular channel 5 for the conductor to pass through. After bending, the blank is held under preset pressure for a preset time (e.g., 0.5s-3s) to fully release the internal stress generated during the forming process. After bending and holding the shape, the wire clamp product is obtained.

[0032] The bending and forming module in this embodiment has a closed cavity that matches the final shape of the wire clip. The closed cavity enables the wire clip to be precisely bent and shaped, ensuring the product's shape accuracy.

[0033] Steps 2 to 5 above are all completed continuously and automatically on this multi-station precision stamping die. The transfer of blanks between each step is achieved automatically by a gripping robot, with no human intervention throughout the process, which improves production efficiency and processing accuracy.

[0034] The two-bending process described in this embodiment is a superior manufacturing process. The core is to release the forming stress through step-by-step bending, and it does not limit the number of bending times. In actual production, three or more bending processes can be flexibly adopted according to the thickness and material of the blank. As long as step-by-step bending can be achieved, internal stress can be effectively released, and forming accuracy can be guaranteed, it is within the protection scope of this process.

[0035] Example 2 Based on Example 1, this example provides a specific process example: Step 1: Cut a rectangle with a length of about 387mm from a T2 copper strip with a thickness of 12.0mm (H1) and a width of 100mm (purity ≥99.9%, conductivity ≥98%) as the blank.

[0036] Step 2: In the punching and precision cutting composite module, 12 Φ14mm through holes (deviation ±0.1mm) are punched on the blank. The inner punch has a 10° guide cone angle at its front end, and the single-sided gap between the inner punch and the cavity is 0.06mm. At the same time, the outer cutting blade of the upper module simultaneously completes the cutting off of the four corners of the blank. Meanwhile, the center positioning line convex strip completes the forming of the center positioning line of the two arc-shaped convex 4, resulting in the following... Figure 3 The first processed blank 10 is shown.

[0037] Step 3: Feed the first-processed blank 10 into the punching die, and forge an arc-shaped punch 4 with a diameter D of 35mm and a depth H2 of 10mm onto the first-processed blank 10, resulting in the following: Figure 4 and Figure 5 The second-processed blank 20 is shown in (H2 / 2R1=0.28).

[0038] Under temperature-controlled venting conditions, the mold temperature is 120℃ during the punching process, and the temperature of the blank 20 during the second processing is room temperature 25℃. This process actually utilizes the punching-forging composite mechanism, which allows the material in this area to flow plastically and the structure to become dense. The bottom of the cavity of the lower die is provided with a vent hole with a diameter of 0.8mm to ensure sufficient forming.

[0039] Step 4: Feed the second-processed blank 20 into the pre-bending die. The upper die platen and lower die V-block simultaneously pre-bend the two wire clamp sections of the second-processed blank 20 to 85° (the two wire clamps from...). Figure 5 (If the elements are located on the same plane, bend them towards each other until they reach 85° and stop bending), the result is as follows: Figure 6 The third-processed blank 30 is shown.

[0040] Step 5: Feed the third-processed blank 30 into the bending forming module. Through the upper and lower mold cavities, the two wire clamp portions of the third-processed blank 30 are bent to 90° by precision pressing (the two wire clamps from... Figure 5 The two wires are located on the same plane, bent at 90° towards each other, so that the two wire clamps are parallel, and after holding the pressure for 0.4s to set, the result is as follows: Figure 7 The cable clamp product 40 shown has a final bending radius R2 of 15mm.

[0041] Performance testing was conducted on the qualified products obtained from the embodiments of the present invention. The inner wall of the arc-shaped convex 4 was smooth and without any burrs. After clamping the qualified products with the wires, a mechanical vibration test (frequency 30Hz, duration 100 hours) was performed. After the test, the product did not damage the surface of the wires, and the clamping force decreased by less than 5%. In contrast, the wires clamped by products of the same specifications produced by traditional stamping and bending processes showed visible wear in the insulation layer, and the clamping force decreased by more than 15%. This indicates that the entire process provided in this embodiment has achieved a significant and fundamental improvement in product quality, precision, and reliability compared to the prior art.

[0042] Example 3 The production process of the aforementioned embodiment, under the condition that the blank and processing mold are in a stable state, can achieve a high level of forming accuracy for mass-produced wire clamps. The accuracy of stamping each through hole can reach ±0.1mm, the parallelism value of the two wire clamps is ±0.8°, and the roundness error of the circular channel 5 formed by the two arc-shaped convex 4 is less than 0.1mm. During mass production, due to factors such as differences in blank size and fluctuations in mold bending and pressure holding process parameters, some products may still experience varying degrees of springback after bending and forming of the wire clamps. This can easily lead to problems such as wire clamp parallelism deviation, insufficient centering of the arc-shaped convex, and coaxiality deviation of the locking hole. In response to this, if... Figure 8 As shown, the strategy adopted in production is to inspect and correct the outgoing clamp products, discarding defective products and obtaining qualified products. This process involves inspecting the dimensions and precision of the outgoing clamp products in step 5, performing targeted correction on defective products, re-inspecting the corrected products, and finally discarding all defective products, retaining the qualified products, and obtaining qualified copper or copper-aluminum transition power equipment outgoing clamps that all meet the preset design requirements, thus improving product consistency.

[0043] The above-mentioned testing process can be carried out manually or semi-automatically with the help of station equipment. In this embodiment, examples are given as follows: Figure 9 The inspection device 100 shown includes a rotary table 101 with four working stations (loading, image acquisition, transfer of qualified / unqualified products, and correction), a support plate 102, a transfer robotic arm 103, an image acquisition component, a correction mold 105, and a control unit. The support plate 102 has a limiting port adapted to the connecting bridge to achieve positioning and automatic centering of the wire clamps. The transfer robotic arm 103 has at least three corresponding to the loading station, the qualified / unqualified product transfer station, and the correction station, used to transfer the corresponding wire clamp products 40. The image acquisition component acquires multi-dimensional contour image information of the wire clamps through three cameras.

[0044] The specific testing and correction steps include: Loading and positioning: At the loading station, the wire clamp product 40 is vertically inserted and fixed to the carrier plate 102, so that the two wire clamps are in contact with the two sides of the carrier plate 102 to ensure stable posture during transportation and testing. Before loading, it is preferable to let the wire clamp product 40 be naturally left to stand without external force for aging stabilization treatment.

[0045] Image acquisition and parameter calculation: The wire clamp product 40 is transferred to the image acquisition station. The camera 104 simultaneously acquires images of the outer side panel and vertical side of the wire clamp. After the control unit preprocesses the images, it extracts the contours and identifies the feature points to quantify and calculate the parallelism of the wire clamp and the alignment of the locking hole 6.

[0046] Grading and processing: The calculated values ​​are compared with the preset thresholds of the control unit, and the products are classified and processed according to the judgment results. If both parallelism and hole alignment meet the qualified thresholds, the product is judged as qualified and transferred to the qualified product storage area. If the parallelism is qualified but the hole alignment exceeds the threshold, the product is judged as a structural defect product not caused by springback and transferred to the non-qualified product area for rejection. If the parallelism exceeds the qualified threshold but is within the correctable threshold, the product is judged as a springback correctable product and transferred to the correction station for correction processing.

[0047] During the correction process, the correctable product is first positioned on the lower die of the correction mold 105. The control unit retrieves the matching upper die pressing stroke parameters based on the blank thickness and parallelism values. The two correction blocks of the upper die apply force to the two sides of the arc-shaped protrusion 4 of the first wire clamp 1 for correction. After applying force, the product is reset to complete the correction.

[0048] Re-inspection and rejection: After correction, the cable clamps are re-loaded and the above inspection and judgment steps are repeated. If the re-inspection is qualified, the product is qualified; if the re-inspection is unqualified, the product is corrected again or rejected. Finally, qualified cable clamps that meet the requirements are obtained.

[0049] The above process forms a complete quality control closed loop from inspection to correction and re-inspection. Even if affected by unavoidable production factors such as differences in blank size and slight fluctuations in bending and pressure holding process parameters of different molds, high-precision wire clamp products can be obtained in the end. It also improves the consistency of the wire clamp products leaving the factory. Through the above inspection and correction process, the factory qualification rate of wire clamp products is increased to over 99.5%.
