Description

Technical Field

[0001] This invention relates to the field of copper busbar bending die technology, and more specifically, to a positioning and guiding device for a copper busbar non-marking bending die. Background Technology

[0002] The core function of the copper busbar non-marking bending die is to eliminate surface indentations and scratches during bending, protect the smoothness and conductivity of the copper busbar, and improve dimensional accuracy, production efficiency and safety.

[0003] Chinese Patent Publication No. CN217070436U discloses a CNC bending die for copper busbars, relating to the field of CNC bending technology. This utility model includes a base, two electric slide rails mounted on the upper side of the base, a sliding plate fixed to the output end of each slide rail, a bending section mounted on the upper side of the sliding plate, a fixing plate fixed to the upper side of the base, and a positioning block mounted on the upper side of the fixing plate; both ends of the upper side of the fixing plate are rotatably fitted with screws.

[0004] The above technical solution enables the bending of copper busbars into different shapes, and is easy to assemble and disassemble, with higher applicability. In traditional copper busbar bending dies, the copper busbar is first placed on the lower die, and bending is performed by the cooperation of the upper and lower dies. However, during the bending process, the bottom surface of the copper busbar contacts the edge of the bending groove of the die. As the bending progresses, the copper busbar and the edge of the bending groove undergo a large relative displacement, resulting in friction and scratches on the bottom surface of the copper busbar, which affects the bending quality of the copper busbar by the die. The existing rotor-type die can increase the contact area between the rotating surface and the copper busbar, but during the bending process, the relative displacement between the rotating surface and the surface of the copper busbar causes friction and scratches on the surface of the copper busbar, which also affects the bending quality of the copper busbar by the die and the appearance smoothness of the bent copper busbar.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) When using the positioning and guiding device of this copper busbar seamless bending die, during the bending process of the copper busbar plate, the upper die moves downward, carrying the bending block and guide pillar downward. The guide pillar moves downward and matches and inserts with the guide sleeve. The bending block moves downward to bend the copper busbar plate at the required bending point. The two sides of the copper busbar plate at the bending point move towards each other, causing the upper and lower rotating wheels to follow the movement of the two sides of the plate. The slide and the fixed cross plate follow the upper and lower rotating wheels to move towards each other, causing the cross plate to follow the arc block to move towards each other in the arc groove. During the movement of the two sides of the copper busbar plate at the bending point towards each other, since the arc block moves synchronously with the bending plate surface of the copper busbar plate in the arc groove, the relative displacement between the upper and lower rotating wheels and the surface of the copper busbar plate is reduced. Moreover, the upper and lower rotating wheels adopt a roller design, and the upper and lower rotating wheels roll on the surface of the copper busbar plate, replacing surface contact with rolling contact, reducing scratches on the surface of the copper busbar plate, ensuring the bending quality of the copper busbar plate by the die, and also ensuring the smoothness of the appearance of the copper busbar plate after bending.

[0016] 2) When using the positioning and guiding device of this copper busbar seamless bending die, the threaded rod is screwed into the direction of the movable frame on the surface of the crossbeam according to the transverse length of the copper busbar. The screwing of the threaded rod drives the movable frame to move, so that the two sliding rods follow the movable frame. The movement of the movable frame drives the sliding frame and the fixed crossbeam to move. The movement of the sliding frame and the fixed crossbeam drives the mounting frame and the rotating wheels to move. After the two pairs of rotating wheels move towards each other, the distance between the rotating wheels is adapted to the transverse length of the copper busbar, realizing the processing of copper busbars of different specifications and lengths, increasing the practicality and functionality of the die.

[0017] 3) When using the positioning and guiding device of this copper busbar seamless bending die, the copper busbar plate is pushed from one end of the lower die. When the copper busbar plate passes the roller at one end of the slide, the roller at one end of the slide moves upward after being squeezed according to the thickness of the copper busbar plate. The movement of the mounting frame moves the slide upward inside the vertical groove. When the roller at one end of the slide rolls on the surface of the copper busbar plate, the roller near the fixed horizontal plate rolls on the bottom surface of the copper busbar plate. At this time, the height of the slide automatically adjusts according to the thickness of the copper busbar plate. While ensuring the bending quality of the copper busbar plate, it can bend copper busbar plates of different thicknesses, further increasing the practicality and function of the die.

[0021] Please see Figure 1 - Figure 11A positioning and guiding device for a copper busbar seamless bending die includes an upper die 1 and a matching lower die 2. The upper die 1 and lower die 2 are conventional dies for bending copper busbars 3 in the prior art. Guide pillars 38 are fixedly installed at the four corners of the bottom surface of the upper die 1, and guide sleeves 39 matching the guide pillars 38 are provided at the four corners of the surface of the lower die 2. The cooperation of the guide pillars 38 and guide sleeves 39 achieves guiding engagement and disengagement of the die. A copper busbar 3 is placed on the surface of the lower die 2.

A bending block 4 is fixedly installed on the bottom surface of the upper die 1, and a V-groove 5 matching the bending block 4 is opened on the surface of the lower die 2. The cooperation of the bending block 4 and the V-groove 5 achieves bending of the copper busbar 3. Support rings 6 are provided on both sides of the lower mold 2. The surfaces of the two support rings 6 are symmetrically provided with arc-shaped grooves 7. Matching arc-shaped blocks 8 are slidably connected inside each of the two arc-shaped grooves 7. A movable frame 10 is provided on one side of the arc-shaped block 8. A fixed horizontal plate 11 is fixedly installed on the bottom surface of the movable frame 10. The design of the fixed horizontal plate 11 allows the rotating wheel 15 near one end of the fixed horizontal plate 11 to support the copper busbar 3. A vertical groove 12 is provided on the surface of the movable frame 10. A slide 13 is slidably connected inside the vertical groove 12. The sliding design of the slide 13 allows for support of copper busbars 3 of different thicknesses. Mounting brackets 14 are fixedly installed on one end surface of both the slide 13 and the fixed horizontal plate 11. A rotating wheel is symmetrically connected inside any one of the mounting brackets 14. The surface of the wheel 15 is equipped with a rubber pad. The wheel 15 contacts the surface of the copper busbar 3. During the bending process of the copper busbar 3, the wheel 15 rolls on the surface of the copper busbar 3 to avoid scratching the surface of the copper busbar 3. The corresponding inner wall of the vertical groove 12 is provided with multiple holes and slots 16. The side surface of the slide 13 is provided with a slot 17. A fixing plate 18 is fixedly installed inside the slot 17. The surface of the fixing plate 18 is slidably connected with a locking rod 19 that matches the holes and slots 16. During the bending process of the copper busbar 3, the upper mold 1 moves downward, taking the bending block 4 and the guide pillar 38 downward. The guide pillar 38 moves downward and matches and inserts with the guide sleeve 39. The bending block 4 moves downward to bend the copper busbar 3 at the required bending point. The two side plates move towards each other, causing the upper and lower rotating wheels 15 to move along with the two side plates. The slide 13 and the fixed cross plate 11 move towards each other with the upper and lower rotating wheels 15, causing the cross frame 9 to move towards each other with the arc block 8 in the arc groove 7. During the movement of the two side plates towards each other at the bending point of the copper busbar 3, the arc block 8 moves synchronously with the bending surface of the copper busbar 3 in the arc groove 7, thereby reducing the relative displacement between the upper and lower rotating wheels 15 and the surface of the copper busbar 3. Moreover, the upper and lower rotating wheels 15 adopt a roller design, and the upper and lower rotating wheels 15 roll on the surface of the copper busbar 3, replacing surface contact with rolling contact, reducing scratches on the surface of the copper busbar 3, ensuring the bending quality of the copper busbar 3 by the mold, and also ensuring the smoothness of the appearance of the copper busbar 3 after bending.

[0022] Please see Figure 1 - Figure 4 The rotating wheel 15, which is close to the fixed horizontal plate 11, is flush with the plane of the lower mold 2. After the copper busbar 3 is placed on the surface of the lower mold 2, the bottom and surface of the copper busbar 3 are in contact with the rotating wheel 15.

[0023] Please see Figure 9 - Figure 11 An installation plate 20 is fixedly installed inside the slot 17. A through guide rod 21 is slidably connected to the surface of the installation plate 20. A wedge block 22 is fixedly installed at one end of the guide rod 21. One end of the locking rod 19 is in contact with the surface of the wedge block 22. The design of the wedge block 22 is to compress the locking rod 19.

[0024] Please see Figure 9 - Figure 11 A spring 23 for resetting the movement of the guide rod 21 is sleeved on its surface. One end of the spring 23 is fixedly connected to the mounting plate 20, and the other end of the spring 23 is fixedly connected to the wedge block 22. A spring 25 for resetting the movement of the locking rod 19 is sleeved on its surface. One end of the spring 25 is fixedly connected to the surface of the fixing plate 18, and the other end of the spring 25 is fixedly connected to the surface of the locking rod 19. The spring 25 is used for resetting the movement of the locking rod 19.

[0025] The side surface of the slide 13 is provided with a rotating groove 26 that communicates with the slot 17. The rotating frame 27 is rotatably connected inside the rotating groove 26. The bottom end of the rotating frame 27 is rotatably connected to a rotating roller, and the surface of the rotating roller is equipped with a rubber sleeve. The design of the rotating roller reduces the friction on the surface of the copper busbar 3. An arc-shaped rail 28 is fixedly installed on the side surface of the rotating frame 27. The other end of the guide rod 21 contacts the inner wall of the arc-shaped rail 28. A spring shaft 29 is provided between the rotating groove 26 and the rotating frame 27. The spring shaft 29 is a conventional elastic reset shaft in the prior art. The rotating frame 27 is rotatably connected to the rotating groove 26 through the spring shaft 29. The arc-shaped rail 28 and the spring shaft 29 are on the same axis. The arc-shaped rail 28 rotates with the rotating frame 27 to compress the guide rod 21.

[0026] Please see Figure 6 - Figure 9 A spring 30 is elastically connected between the slide 13 and the vertical groove 12. One end of the spring 30 is fixedly connected to the slide 13, and the other end of the spring 30 is fixedly connected to the inner top surface of the vertical groove 12. The spring 30 is used for the movement reset of the slide 13.

[0027] Please see Figure 1 - Figure 6A spring 31 is elastically connected between the arc-shaped block 8 and the arc-shaped groove 7. The spring 31 is used for the movement reset of the arc-shaped block 8. One end of the spring 31 is fixedly connected to the arc-shaped block 8, and the other end of the spring 31 is fixedly connected to the inner wall of the arc-shaped groove 7. A limiting plate 36 for limiting the arc-shaped block 8 is symmetrically fixedly installed on the surface of the support ring 6. The limiting plate 36 is used to limit the arc-shaped block 8 so that the rotating wheel 15 near the fixed horizontal plate 11 is flush with the plane of the lower mold 2.

[0028] Please see Figure 1 - Figure 8 A crossbeam 9 is fixedly mounted on the surface of the arc-shaped block 8, and a rotating seat 32 is fixedly mounted on the surface of the movable frame 10. A through-type threaded rod 33 is threadedly connected to the surface of the crossbeam 9. One end of the threaded rod 33 is rotatably connected to the rotating seat 32. Through-type sliding rods 34 are symmetrically slidably connected to the surface of the crossbeam 9. The two sliding rods 34 are located on both sides of the threaded rod 33. The design of the threaded rod 33 realizes the self-locking after the movable frame 10 is adjusted. The sliding rods 34 are used to guide the movement of the movable frame 10.

[0029] One end of each of the two slide rods 34 is fixedly connected to the movable frame 10. A spring 35 is sleeved on the surface of each of the two slide rods 34. One end of the spring 35 is fixedly connected to the movable frame 10, and the other end of the spring 35 is fixedly connected to the cross frame 9. The spring 35 is used for the movement reset of the slide rod 34.

[0030] The surface of the lower mold 2 is symmetrically provided with slots 37. The two slots 37 are located on both sides of the V-groove 5. The support ring 6 and the lower mold 2 are fixedly installed with a connecting frame 40. The plane height of the two slots 37 is flush with the plane of the lower mold 2, and the plane height of the two slots 37 is greater than the plane height of the V-groove 5.

[0031] The steps of using this invention are as follows: When using the positioning and guiding device of this copper busbar seamless bending mold, according to the lateral length of the copper busbar plate 3, first rotate the threaded rod 33. The threaded rod 33 is rotated in the direction of the movable frame 10 on the surface of the cross frame 9. The rotation of the threaded rod 33 moves the movable frame 10, causing the two sliding rods 34 to move with the movable frame 10 and stretch the spring 5 35. The movement of the movable frame 10 moves the sliding frame 13 and the fixed cross plate 11. The movement of the sliding frame 13 and the fixed cross plate 11 moves the mounting frame 14 and the rotating wheel 15. After the two pairs of rotating wheels 15 have moved towards each other, the distance between the rotating wheels 15 is adapted to the lateral length of the copper busbar plate 3. Then, the copper busbar plate 3 is placed on the surface of the lower mold 2. During the placement of the copper busbar plate 3, the copper busbar plate 3 is first placed from one of the lower mold 2... As the copper busbar 3 advances, it passes the roller 15 at one end of the slide 13. Based on the thickness of the copper busbar 3, the copper busbar 3 presses against the roller 15 at one end of the slide 13. The roller 15, under pressure, moves, causing the mounting bracket 14 to move upwards. The mounting bracket 14 then moves the slide 13 upwards within the vertical groove 12, compressing the spring 30. When the roller 15 at one end of the slide 13 rolls on the surface of the copper busbar 3, the roller 15 near the fixed horizontal plate 11 rolls on the bottom surface of the copper busbar 3. At this time, the slide 13 automatically adjusts its height according to the thickness of the copper busbar 3. As the copper busbar 3 continues to advance, its surface presses against the rotating frame 27. The rotating frame 27 rotates within the rotating groove 26, causing the arc-shaped rail 28 to rotate. The arc-shaped rail 28 rotates gradually... The guide rod 21 is gradually compressed. After being compressed, the guide rod 21 slides on the surface of the mounting plate 20. The movement of the guide rod 21 causes the wedge block 22 to move, stretching the spring 23. During the movement of the wedge block 22, it compresses the locking rod 19. The locking rod 19 slides on the surface of the fixed plate 18, compressing the spring 25. The locking rod 19 slides and inserts into the slot 16, locking the slide 13 inside the vertical slot 12. At the same time, the distance between the upper and lower rotating wheels 15 is the same as the thickness of the copper busbar 3. During the bending process of the copper busbar 3, the upper mold 1 moves downward, causing the bending block 4 and the guide support 38 to move downward. The guide support 38 moves downward and matches and inserts into the guide sleeve 39. The bending block 4 moves downward to bend the copper busbar 3 at the required bending point. As the bending block 4 continues to move downward, at this time... When the copper busbar 3 is bent, the two sides of the bent section move towards each other, causing the upper and lower rotating wheels 15 to follow the movement of the two sides. The slide 13 and the fixed cross plate 11 move towards each other with the upper and lower rotating wheels 15, causing the cross frame 9 to follow the arc block 8 and move towards each other within the arc groove 7, stretching the spring 31. During the movement of the two sides of the bent section of the copper busbar 3, the arc block 8 moves synchronously with the bent surface of the copper busbar 3 within the arc groove 7, thereby reducing the relative displacement between the upper and lower rotating wheels 15 and the surface of the copper busbar 3. Moreover, the upper and lower rotating wheels 15 adopt a roller design, rolling on the surface of the copper busbar 3, reducing scratches on the surface of the copper busbar 3. After the copper busbar 3 is bent, the upper mold 1 and the lower mold 2 separate.At this time, the copper busbar 3 is in a bent state (the strength of the copper busbar 3 is much greater than the elastic force of spring 31). During the process of removing the bent copper busbar 3, the threaded rod 33 is first rotated to reset. The reset of the threaded rod 33 causes the movable frame 10 to reset. The movement of the movable frame 10 causes the slide 13 and the fixed horizontal plate 11 to reset. The reset movement of the slide 13 causes the rotating frame 27 to move. When the rotating frame 27 is separated from the surface of the copper busbar 3, it is reset under the action of the spring shaft 29, so that the locking rod 19 is reset and disengaged from the slot 16 under the action of spring 25. At this time, the slide 13 is unlocked. After all four slides 13 are unlocked, the bent copper busbar 3 is removed. After the copper busbar 3 is removed, the arc block 8 is reset under the action of spring 31. During the bending process of the copper busbar 3, the upper mold 1 moves downward, causing the bending block 4 and the guide pillar 38 to move downward. The downward movement engages with the guide sleeve 39. The bending block 4 moves downward to bend the copper busbar 3 at the required bending point. The two sides of the copper busbar 3 at the bending point move towards each other, causing the upper and lower rotating wheels 15 to follow the movement of the two sides. The slide 13 and the fixed cross plate 11 follow the upper and lower rotating wheels 15 towards each other, causing the cross frame 9 to follow the arc-shaped block 8 towards each other within the arc-shaped groove 7. During the relative movement of the two sides of the copper busbar 3 at the bending point, the arc-shaped block 8 moves synchronously with the bending surface of the copper busbar 3 within the arc-shaped groove 7, thereby reducing the relative displacement between the upper and lower rotating wheels 15 and the surface of the copper busbar 3. Moreover, the upper and lower rotating wheels 15 adopt a roller design, rolling on the surface of the copper busbar 3, replacing surface contact with rolling contact, reducing scratches on the surface of the copper busbar 3, ensuring the bending quality of the copper busbar 3 by the mold, and also ensuring the smoothness of the appearance of the copper busbar 3 after bending.

[0032] Based on the transverse length of the copper busbar 3, the threaded rod 33 is screwed into the movable frame 10 on the surface of the crossbeam 9. The screwing of the threaded rod 33 causes the movable frame 10 to move, so that the two sliding rods 34 follow the movable frame 10. The movement of the movable frame 10 causes the sliding frame 13 and the fixed crossbeam 11 to move. The movement of the sliding frame 13 and the fixed crossbeam 11 causes the mounting frame 14 and the rotating wheel 15 to move. After the two pairs of rotating wheels 15 move towards each other, the distance between the rotating wheels 15 is adapted to the transverse length of the copper busbar 3, so as to realize the processing of copper busbars 3 of different specifications and lengths, which increases the practicality and functionality of the mold.

[0033] The copper busbar 3 is pushed from one end of the lower mold 2. When the copper busbar 3 passes the roller 15 at one end of the slide 13, the roller 15 at one end of the slide 13 is squeezed according to the thickness of the copper busbar 3, and moves, carrying the mounting frame 14 upward. The mounting frame 14 moves, carrying the slide 13 upward inside the vertical groove 12. When the roller 15 at one end of the slide 13 rolls on the surface of the copper busbar 3, the roller 15 at the end near the fixed horizontal plate 11 rolls on the bottom surface of the copper busbar 3. At this time, the slide 13 automatically adjusts its height according to the thickness of the copper busbar 3. While ensuring the bending quality of the copper busbar 3, it can bend copper busbar 3 of different thicknesses, further increasing the practicality and function of the mold.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
