Description

Technical Field

[0001] This utility model relates to the field of metal wire processing technology, and in particular to a 3D bending head for metal parts. Background Technology

[0002] With the development of the new energy vehicle industry, the demand for flat cables in vehicle high-voltage systems and battery packs has surged. Flat cables, due to their advantages such as interference resistance and resistance to high and low temperatures, have become a core component for ensuring the safety of electrical systems. However, the internal wiring of new energy vehicles is compact, requiring flat cables to undergo complex bends at multiple angles and dimensions, while maintaining structural and electrical integrity, placing extremely high demands on processing equipment.

[0003] Currently, flat line bending relies on multi-equipment step-by-step operations or manual assistance, resulting in cumbersome processes: First, the process is severely fragmented, with bending, twisting, and cutting requiring multiple pieces of equipment. Material transfer easily leads to positioning deviations, resulting in low pass rates and difficulty in meeting component consistency requirements. Second, there is a lot of manual intervention, with process transfer, mold replacement, and status monitoring all requiring manual labor, leading to low processing efficiency and restricting vehicle production capacity. Third, there is poor adaptability, with complex shapes requiring multiple parameter adjustments, and the single limiting method easily leading to bending deviations, failing to meet the requirements of high-voltage systems. Fourth, the degree of automation is low, lacking the ability to interface with intelligent manufacturing systems, resulting in high management costs and insufficient scheduling flexibility.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a 3D bending head for metal parts, making it more valuable for industrial applications. Utility Model Content

[0014] Furthermore, the bending part includes a gearbox two fixed on the connecting plate. A second motor is fixed at the lower end of the gearbox two. The second motor drives the die head to rotate through the gear set installed in the gearbox two. The die head has a slot for vertical positioning of the metal part.

The components are assembled in this way to achieve the oblique torsion operation of the metal parts and meet the multi-dimensional bending requirements of the metal parts.

[0020] Furthermore, the cutting section includes a cutting support fixed to the mounting head. The tail end of the cutting support is a vertically arranged baffle. A movable seat is movably mounted on the cutting support via a slide rail. A cutting shear is movably mounted on the movable seat via a shaft.

A discharge drive gear is mounted on the output shaft of the fourth motor. The discharge drive gear meshes with the discharge driven gear on the outer ring of the discharge head. A through guide sleeve is provided inside the discharge head to guide the metal parts. The other end of the discharge head has a discharge opening, and the opening is initially horizontal. All components are assembled in this structure to provide guidance and power support for the conveying and discharge of the metal parts.

[0024] Furthermore, there is a horizontally positioned clamp on one side of the opening in its initial state, and the gap between the clamps can lock the metal part protruding from the opening in its initial state on both sides.

[0025] On one side of the discharge head opening in its initial state, there is a horizontally positioned clamp with a gap between them. This gap can hold the metal part extending from the opening on both sides in its initial state. This design can provide lateral restraint for the metal part extending from the opening, and together with the twisting of the discharge head, it can fulfill the multi-dimensional bending requirements of the metal part.

[0026] By means of the above-described solution, the present invention has at least the following advantages: 1. Achieve process integration and simplify processing flow: By arranging mounting bases in a circular array on the support plate, the bending part, die head pressing block, rotation and twisting part, and cutting part are integrated into the same equipment. This eliminates the need for multiple equipment to operate in steps, saves the transfer of metal parts between different equipment, avoids positioning deviations caused by material transfer, greatly improves the processing qualification rate, and reduces the equipment footprint and initial investment costs, which meets the compact requirements of new energy vehicle production lines.

[0027] 2. Reduce manual intervention and improve processing efficiency: The actions of each functional component are driven by automated structures such as motors and cylinders. For example, the bending part is driven by a second motor to rotate the die head, and the cutting part is cut by the cooperation of a push cylinder and a bidirectional cylinder. There is no need for manual process transfer, mold replacement and status monitoring, which effectively shortens the processing cycle of a single flat line, breaks through the production capacity bottleneck and adapts to the high-efficiency cycle requirements of new energy vehicle production lines.

[0028] 3. Improved bending accuracy and stability: The bending section uses a die head slot and a protrusion to achieve vertical and horizontal bidirectional positioning of the metal part. The rotating twisting section clamps the metal part with the gap of the torsion bar. The chuck at the discharge head provides lateral positioning of the protruding metal part. This multi-directional positioning structure prevents displacement of the metal part during processing. At the same time, the mounting head is guided by the guide rail and guide groove and reset by the tension spring, ensuring precise component movement. This solves the bending deviation problem caused by the single positioning method in traditional systems and meets the precision requirements of high-voltage systems in new energy vehicles.

[0029] 4. Enhanced adaptability to meet complex processing needs: The mounting base can be selected to install different functional components at corresponding positions according to processing requirements, and the linear module drives the mounting head to move back and forth, which can flexibly adjust the position of the components to adapt to metal parts of different specifications and shapes; the rotating and twisting part can realize oblique twisting, and with the rotatable discharge head, it can complete complex multi-dimensional processing such as "horizontal bending + oblique twisting", without the need to adjust the equipment parameters many times, solving the problem of poor adaptability of traditional equipment and reducing processing costs.

[0030] 5. Enhance automation and adapt to intelligent manufacturing: Each functional component uses motors and cylinders as power sources, which can be connected to intelligent manufacturing systems to realize automatic retrieval of processing parameters and linkage of actions, eliminating the need for manual recording of production data and reducing management costs; at the same time, the equipment structure has a high degree of integration, which facilitates real-time uploading of production data and fault early warning, improves the flexibility of production scheduling, and can quickly respond to the needs of new energy vehicle order changes, which is in line with the development trend of intelligent manufacturing in the industry.

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0036] See Figure 1 The support bracket 1 provides stable support for the overall structure. The support plate 2, fixed to the end face of the support bracket 1, serves as the mounting base for each functional component. The rotatable discharge head 3 on the axis of the support plate 2 is used for conveying and guiding the metal parts. Multiple mounting seats 4 are arranged in a circular array around the axis on the surface of the support plate 2. The corresponding mounting seats 4 can be selected according to the processing requirements of the metal parts to install the bending part 5, the die head pressure block 6, the rotating twisting part 7, and the cutting part 8. During processing, the metal parts are first bent horizontally under the cooperation of the installed bending part 5 and the die head pressure block 6. After the horizontal bending is completed, the rotating twisting part 7 cuts the metal parts. The metal parts are twisted at an angle. After the bending process is completed, the cutting part 8 cuts them. The bending part 5, the die head pressure block 6, the rotating twisting part 7 and the cutting part 8 are integrated by the circular array of mounting seats 4 on the support plate 2. This eliminates the need for multiple equipment to operate in steps, reduces the metal parts transfer process, and allows for flexible adaptation to the processing position with the rotatable discharge head 3, greatly simplifying the processing flow. At the same time, the functional components are centrally arranged on the support plate 2, relying on the stable support of the bracket 1 to improve the stability of the overall processing process. This meets the needs of completing horizontal bending, oblique twisting and cutting of metal parts in one stop, reducing the processing complexity.

[0037] See Figure 2The mounting base 4 includes a connecting plate 9 fixedly mounted to the support plate 2. The connecting plate 9 provides a mounting carrier for other components of the mounting base 4. The linear module equipped on the connecting plate 9 can drive the mounting head 10 mounted on it to move back and forth. The mounting head 10 can select to install any one of the following components according to the processing requirements of the metal parts: bending part 5, die head pressure block 6, rotating twisting part 7, or cutting part 8. When it is necessary to adjust the relative position of the functional component and the metal part, the linear module drives the mounting head 10 to move back and forth, thereby driving the corresponding functional component mounted on the mounting head 10 to move synchronously to adapt to the position requirements of different processing stages. Through the fixed connection between the connecting plate 9 and the support plate 2, the overall structure of the mounting base 4 is ensured to be stable, providing a reliable mounting foundation for the functional components. The design of the linear module driving the mounting head 10 to move back and forth can flexibly adjust the position of functional components such as bending part 5 and die head pressure block 6, which can adapt to the processing requirements of metal parts of different specifications. At the same time, the mounting head 10 can flexibly switch to install different functional components, improving the versatility of the mounting base 4.

[0038] Linear modules include, but are not limited to, linear sliders, cylinders, and electric lead screws.

[0039] See Figures 2-3 This provides an embodiment for a linear module.

[0040] A gearbox 11 is fixed to one side of the connecting plate 9. The lower end of the gearbox 11 is fixedly connected to the first motor 12. When the mounting head 10 needs to be driven, the first motor 12 starts, and the drive gear 13 mounted on its output shaft rotates accordingly. The drive gear 13 meshes with the driven gear 14 mounted in the gearbox 11 via the connecting shaft 15, thereby driving the driven gear 14 and the connecting shaft 15 connected to it to rotate synchronously. The upper end of the connecting shaft 15 is fixedly connected to the rotating seat 16 movably mounted on the connecting plate 9 via a bearing. When the connecting shaft 15 rotates, it will drive the rotating seat 16 to rotate together. A connecting rod 17 is movably mounted on the outer circle of the rotating seat 16 via a shaft and a bushing. The rotation of the rotating seat 16 will pull or push the connecting rod 17, and the other end of the connecting rod 17 is connected to the mounting head 10 via a shaft and a bushing. The mounting head 10 is movably connected, and the connecting rod 17 ultimately drives the mounting head 10 to achieve the corresponding action. Power is provided by the first motor 12, and through the meshing transmission of the drive gear 13 and driven gear 14, as well as the linkage of the connecting shaft 15, rotating seat 16, and connecting rod 17, the power can be stably transmitted to the mounting head 10, ensuring that the action of the mounting head 10 is precise and controllable. At the same time, the gearbox 11 protects the internal gear set, reduces the influence of external factors on the transmission structure, and extends the service life of the components. Moreover, the components are assembled in an orderly manner through fixed or movable connections, forming a stable power transmission system based on the connecting plate 9. This provides reliable power support for the mounting head 10 to drive the bending part 5, die head pressing block 6, and other functional components to complete the processing action, further improving the overall processing stability and reliability of the equipment.

[0041] A guide rail 18 is fixed to the surface of the connecting plate 9. The bottom of the mounting head 10 is provided with a guide groove that mates with the guide rail 18. When the mounting head 10 moves back and forth under the drive of the power structure, the guide groove will slide synchronously along the guide rail 18, providing precise guidance for the movement of the mounting head 10 and preventing the mounting head 10 from deviating during the movement. At the same time, a positioning bolt 19 is screwed into the screw hole at the tail end of the connecting plate 9. A pull plate 20 is movably sleeved on the shaft of the mounting head 10. Positioning bolts 21 are screwed into the screw holes at both ends of the pull plate 20. A tension spring 22 is installed between the positioning bolt 19 and the positioning bolt 21. When the mounting head 10 moves away from the tail end of the connecting plate 9, it will drive the positioning bolt 21 to move synchronously through the pull plate 20, causing the tension spring 22 to be stretched. When the power driving the mounting head 10 disappears, the tension spring 22 will pull the positioning bolt 21 under its own elastic force. 1. Then, the mounting head 10 is driven by the pull plate 20 to reset to the initial position along the guide rail 18. The cooperation between the guide rail 18 and the guide groove can strictly limit the movement trajectory of the mounting head 10, ensuring that the mounting head 10 moves accurately when driving the bending part 5, the die head pressure block 6 and other functional components, avoiding the impact of movement offset on the processing accuracy. The positioning bolt 19 and positioning bolt 21 can not only securely install the tension spring 22, but also adapt to the installation requirements of the tension spring 22 by adjusting its position. The setting of the tension spring 22 can realize the automatic reset of the mounting head 10 without the need for additional power drive, simplifying the equipment structure. At the same time, the movable sleeve design of the pull plate 20 can adapt to the position change during the movement of the mounting head 10, ensuring that the tension spring 22 can always exert stable force. The coordinated action of each component makes the movement of the mounting head 10 both accurate and reliable, providing a strong guarantee for the continuity and stability of subsequent metal part processing.

[0042] See Figure 4 and Figure 5The bending section 5 includes a gearbox 23 fixed to the connecting plate 9. A second motor 24 is fixed to the lower end of the gearbox 23. When the metal part needs to be bent horizontally, the second motor 24 is started, and its power is transmitted to the die head 26 through the gear set installed in the gearbox 23, causing the die head 26 to rotate. Before the die head 26 rotates, the metal part is placed in the slot 27 in the die head 26. The slot 27 limits the metal part vertically, preventing it from shifting vertically. At the same time, the gap between the upward-protruding protrusions 28 at both ends of the slot 27 is used to place the metal part horizontally, keeping it stable in the horizontal direction. As the die head 26 rotates, the metal part gradually completes the horizontal bending under the action of the protrusions 28. The inner side of the protrusions 28 is arc-shaped, which can avoid scratching or damaging the surface of the metal part during the bending process. The combination of the two components provides stable and controllable rotational power to the die head 26, ensuring accurate bending angle of the metal part. The slot 27 is used for vertical torsional bending of the metal part, and the protrusion 28 can restrict the horizontal direction of the metal wire, allowing for horizontal torsional bending of the metal part. The gearbox 23 can protect the internal gear set from external interference and ensure the stability of power transmission. The dual limiting design of the slot 27 and the protrusion 28 fixes the metal part in both vertical and horizontal directions, effectively preventing displacement of the metal part during bending and further improving bending accuracy. The arc-shaped structure on the inner side of the protrusion 28 can make smooth contact with the surface of the metal part during bending, reducing the risk of damage to the metal part and ensuring the structural integrity of the metal part after bending. At the same time, the bending part 5 is fixed on the connecting plate 9, relying on the stable support of the connecting plate 9 to make the entire bending process more reliable, laying a good foundation for the subsequent oblique torsion process of the rotating twisting part 7.

[0043] See Figure 6A die head pressure block 6 is positioned directly above the bending section 5. The die head pressure block 6 is movably mounted within a pressure block mounting base 29 via a shaft. The upper end of the pressure block mounting base 29 is fixedly connected to the telescopic rod of the clamping cylinder 30. The clamping cylinder 30 is fixedly mounted to the mounting head 10 via a fixing block. When the die head 26 of the bending section 5 moves the metal part to prepare for horizontal bending, the clamping cylinder 30 is activated, and its telescopic rod extends downward, pushing the pressure block mounting base 29 downward synchronously. The die head pressure block 6 within the pressure block mounting base 29 then approaches the metal part at the bending section 5 until it contacts the surface of the metal part and applies pressure, firmly pressing the metal part between the slot 27 and the protrusion 28 of the die head 26. During the bending process, the die head pressure block 6 maintains a pressing state on the metal part. After the bending process is completed, the telescopic rod of the clamping cylinder 30 retracts upward, causing the pressure block mounting base 29 and the die head pressure block 6 to reset, releasing the metal part. The die head pressure block 6 is located directly above the bending section 5 to precisely align with the pressing position of the metal part. Working in conjunction with the slot 27 and protrusion 28 of the bending section 5, it forms a multi-directional fixation of the metal part, effectively preventing it from shifting during bending due to force, further improving bending accuracy. The clamping force provided by the clamping cylinder 30 is stable and controllable, and can be flexibly adjusted according to the specifications of the metal part, avoiding damage to the metal part due to excessive pressure or failure of fixation due to insufficient pressure. The die head pressure block 6 is movably mounted in the pressure block mounting seat 29 via a shaft, and can rotate slightly with the bending of the metal part during clamping, ensuring that the clamping force is always evenly applied to the surface of the metal part. Simultaneously, the clamping cylinder 30 is fixedly connected to the mounting head 10, and its position can be adjusted with the movement of the mounting head 10 to adapt to different bending requirements, making the cooperation between the die head pressure block 6 and the bending section 5 more flexible, providing a reliable guarantee for high-quality horizontal bending of the metal part.

[0044] See Figure 6The rotating twisting part 7 includes a torsion motor base 31 fixed on the mounting head 10. A third motor 32 is fixed on one side of the torsion motor base 31. When the metal part needs to be twisted at an angle after horizontal bending, the metal part is first inserted into the gap between multiple independent torsion rods 34 on the surface of the torsion head 33. Then, the third motor 32 starts, and its rotating shaft passes through the torsion motor base 31 and drives the torsion head 33 mounted on the shaft end to rotate synchronously. When the torsion head 33 rotates, it will drive the torsion rods 34 on the surface to rotate together. Since the metal part is inserted into the gap between the torsion rods 34, the torsion rods 34 will drive the metal part to be twisted at an angle until the metal part reaches the preset torsion angle. After the twisting is completed, the third motor 32 stops rotating, and the torsion head 33 and torsion rods 34 return to rest. Then, the twisted metal part is removed from the gap between the torsion rods 34. To facilitate subsequent cutting processes, the torsion motor base 31 provides a stable mounting foundation for the third motor 32 and the torsion head 33, ensuring stable component positions during power transmission. The third motor 32 provides continuous and controllable rotational power to the torsion head 33, ensuring accurate torsion angle of the metal parts and avoiding over- or under-torsion. The gaps between the multiple independent torsion rods 34 can firmly hold the metal parts in place, preventing slippage or displacement during torsion. The independent setting of the torsion rods 34 can adapt to metal parts of different thicknesses. Fixing can be completed simply by selecting the torsion rod 34 with the corresponding gap, without the need for frequent component replacement. In addition, the rotating and twisting part 7 is fixed to the mounting head 10 through the torsion motor base 31, and can adjust its relative position to the metal parts as the mounting head 10 moves, flexibly adapting to the torsion requirements under different processing scenarios.

[0045] The discharge head 3 outputs the flat wire, and the twist head 33 moves forward through the mounting head, so that it is stuck on the flat wire. The twist head 33 can bend the flat wire vertically, which can meet the needs of bending the flat wire at multiple angles and in multiple directions.

[0046] See Figure 6The cutting section 8 includes a cutting support 35 fixed to the mounting head 10. A vertically arranged baffle 36 is provided at the tail end of the cutting support 35. A movable seat 37 is movably mounted on the cutting support 35 via a slide rail. A cutting shear 38 is movably mounted on the movable seat 37 via a shaft. The tail end support rod 39 of the cutting shear 38 has an oblong hole. Two telescopic rods of a two-way cylinder 45 have protrusions that engage with the oblong hole, and the two-way cylinder 45 is fixed to the movable seat 37. A push cylinder 40 fixed to the outside of the baffle 36 has its telescopic rod fixedly connected to the movable seat 37. When the metal part is bent and needs to be cut, the push cylinder 40 is first activated, and its telescopic rod pushes the movable seat 37 along the slide rail of the cutting support 35 towards the metal part until the cutting shear 38 is aligned with the position to be cut on the metal part. Then, the two-way cylinder 45 is activated, and its two telescopic rods drive the tail end support rod 39 of the cutting shear 38 through the oblong hole, causing the cutting shear 38 to move. The cutting head 8 rotates around the axis and closes to complete the cutting of the metal part. After cutting, the telescopic rod of the bidirectional cylinder 45 returns to its original position, causing the cutting shear 38 to open. The telescopic rod of the push cylinder 40 retracts, causing the moving seat 37 to return to its initial position. The cutting support 35 provides a stable mounting base for each component. The cooperation between the slide rail and the moving seat 37 ensures accurate adjustment of the cutting position. The push cylinder 40 can flexibly adjust the position of the moving seat 37 to adapt to the cutting needs of metal parts of different lengths. The bidirectional cylinder 45 drives the cutting shear 38 through the oblong hole, making the cutting action stable and the force controllable, avoiding over-cutting or incomplete cutting. The movable installation design of the cutting shear 38 allows it to flexibly adapt to the position of the metal part during cutting. At the same time, the cutting part 8 is fixed on the mounting head 10 and can be adjusted with the mounting head 10 to further improve the cutting flexibility. The overall structure realizes efficient and accurate cutting of the bent metal part without the need for additional cutting equipment, simplifying the processing flow.

[0047] See Figure 8The discharge head 3 is movably mounted inside the support plate 2 via bearings. A fourth motor 25 is fixed to the support plate 2 via a mounting bracket. A discharge drive gear 41 is mounted on the output shaft of the fourth motor 25. The discharge drive gear 41 meshes with the discharge driven gear 42 on the outer ring of the discharge head 3. The discharge head 3 has a through guide sleeve 43 inside, and the other end of the discharge head 3 has a discharge opening, which is initially horizontal. During processing, the metal part first passes through the guide sleeve 43 and is guided by the guide sleeve 43 to be conveyed towards the discharge opening. When it is necessary to adjust the discharge direction of the metal part to cooperate with bending, twisting, and other processes, the fourth motor 25 is started, and its output shaft drives the discharge drive gear 41 to rotate. The discharge drive gear 41 drives the discharge driven gear 42 and the discharge head 3 connected to it to rotate synchronously through meshing transmission, so that the discharge opening is adjusted from the initial horizontal state to the horizontal state. The required angle ensures that the metal parts can accurately align with subsequent processing components. After the metal parts complete all processing steps, they are finally discharged from the discharge opening. The guide sleeve 43 provides stable guidance for the metal parts, preventing deviation or shaking during transportation and ensuring transportation stability. The fourth motor 25 drives the discharge head 3 to rotate through gear meshing. The transmission process is stable and the angle adjustment is precise, allowing for flexible control of the discharge opening direction to adapt to the multi-dimensional processing position requirements of the metal parts. The discharge head 3 is movably mounted in the support plate 2 through bearings, reducing frictional resistance during rotation and extending the service life of the components. At the same time, the support plate 2 provides a reliable mounting base for the fourth motor 25 and the discharge head 3, ensuring structural stability when all components work together. The overall design integrates the transportation and direction adjustment of the metal parts without manual intervention, improving processing efficiency.

[0048] See Figure 6 On one side of the initial opening of the discharge head 3, there is a horizontally positioned chuck 44. When the metal part is guided by the guide sleeve 43 inside the discharge head 3 and extends out of the initially horizontal opening of the discharge head 3, the gap between the chucks 44 will lock the metal part on both sides of the protruding opening, forming a lateral limit on the metal part. During subsequent processing steps such as horizontal bending and oblique twisting of the metal part, the chucks 44 will always be firmly locked on both sides of the metal part through the gap to prevent the metal part from shifting or shaking due to processing force. When the metal part has completed all processing steps and needs to be sent out from the opening of the discharge head 3, the chucks 44 will release the limit on the metal part, allowing the metal part to be output smoothly.

[0049] The working principle of this utility model is as follows: 1. Metal part extending from the discharge head stage: The metal part first passes through the guide sleeve 43 inside the discharge head 3. The guide sleeve 43 guides the metal part and ensures that the metal part is conveyed along the preset path. The fourth motor 25 fixed on the support plate 2 by the mounting bracket is started. Its output shaft drives the discharge drive tooth 41 to rotate. The discharge drive tooth 41 meshes with the discharge driven tooth 42 on the outer ring of the discharge head 3, thereby driving the discharge head 3 to rotate in the support plate 2 and adjusting the opening of the discharge head 3 to the initial horizontal state. Then, under the guidance of the guide sleeve 43, the metal part extends out from the horizontal opening of the discharge head 3. At this time, the clamps 44 set horizontally on one side of the opening in the initial state are locked on both sides of the metal part extending out of the opening, forming a lateral limit on the metal part and preventing the metal part from shifting laterally during subsequent processing.

[0050] 2. Horizontal bending stage of metal parts: In the mounting seats 4 arranged in a circular array on the surface of the support plate 2, the mounting seats 4 corresponding to the bending part 5 and the die head pressure block 6 begin to operate; First, on the side of the connecting plate 9 fixed to the support plate 2 in the mounting seat 4, the first motor 12 at the lower end of the gearbox 11 starts, and the output shaft drives the drive gear 13 to rotate. The drive gear 13 meshes with the driven gear 14 installed in the gearbox 11 through the connecting shaft 15, driving the connecting shaft 15 and the rotating seat 16 fixed at the upper end to rotate. The rotating seat 16 pulls the mounting head 10 through the connecting rod 17. The bottom guide groove of the mounting head 10 moves along the guide rail 18 on the surface of the connecting plate 9, adjusting the bending part 5 and the die head pressure block 6 to the position where the metal part is to be bent; then, the bending... The second motor 24 at the lower end of the gearbox 23 in the bend 5 starts, and drives the mold head 26 to rotate through the gear set inside the gearbox 23. The metal part is first placed into the slot 27 in the mold head 26 for vertical positioning. The gap between the protrusions 28 at both ends of the slot 27 allows the metal part to be placed horizontally. At the same time, the extension rod of the clamping cylinder 30, which is fixed to the mounting head 10, extends downward from the upper end of the clamping block mounting base 29 where the mold head clamping block 6 is located, pushing the clamping block mounting base 29 to move the mold head clamping block 6 downward, pressing the metal part between the slot 27 and the protrusions 28 of the mold head 26. As the mold head 26 rotates, the metal part completes the horizontal bending under the action of the protrusions 28. After bending, the extension rod of the clamping cylinder 30 retracts, and the mold head clamping block 6 returns to its original position.

[0051] 3. Metal part oblique twisting and chuck auxiliary limiting stage: After the metal part completes horizontal bending, it switches to the mounting base 4 with the rotating twisting part 7 installed; the first motor 12 of the mounting base 4 starts again, and drives the mounting head 10 to move through the transmission structure, so that the rotating twisting part 7 is close to the metal part; the third motor 32 on one side of the torsion motor base 31 in the rotating twisting part 7 starts, and its rotating shaft passes through the torsion motor base 31 to drive the torsion head 33 to rotate. The metal part is stuck in the gap between multiple independent torsion rods 34 on the surface of the torsion head 33. The torsion rods 34 rotate with the torsion head 33, driving the metal part to perform oblique twisting; during this process, the chuck 44 at the opening of the discharge head 3 always maintains a clamping state on both sides of the metal part, and cooperates with the action of the rotating twisting part 7 to prevent the metal part from slipping or displacing during twisting, ensuring accurate twisting angle. After the metal part reaches the preset twisting angle, the third motor 32 stops, and the torsion head 33 and torsion rods 34 are reset.

[0052] 4. Metal Part Cutting Stage: After the metal part is twisted, it is finally switched to the mounting seat 4 with the cutting part 8 installed. The first motor 12 of the mounting seat 4 drives the mounting head 10 to move, so that the cutting part 8 is aligned with the position to be cut on the metal part. The push cylinder 40 on the outside of the baffle 36 in the cutting part 8 is activated, and its telescopic rod pushes the moving seat 37 to move along the slide rail of the cutting support 35 towards the metal part until the cutting shear 38 on the moving seat 37 is aligned with the cutting position. Then, the bidirectional cylinder 45 fixed on the moving seat 37 is activated, and its two telescopic rods pass through the waist-shaped hole on the tail support rod 39 of the cutting shear 38, driving the cutting shear 38 to rotate around the axis and close, completing the cutting of the metal part. After the cutting is completed, the telescopic rod of the bidirectional cylinder 45 is reset to open the cutting shear 38, the telescopic rod of the push cylinder 40 retracts to drive the moving seat 37 back to the initial position, the clamp 44 releases the restriction on the metal part, and the cut metal part is sent out from the opening of the discharge head 3, and the entire processing process is completed.
