Description

Technical Field

[0001] This invention relates to the field of copper cutting technology, and in particular to a copper cutting device for manufacturing high-voltage wires for new energy vehicles. Background Technology

[0002] As a core component for power transmission in electric vehicles, the manufacturing quality of high-voltage lines directly affects the safety and reliability of the entire vehicle. In the manufacturing process of high-voltage lines, copper cutting is one of the key processes. Currently, the industry generally uses traditional sawing cutting equipment, which cuts copper rods through a linear feed method.

[0003] When sawing equipment cuts copper rods, it is often necessary to repeatedly position and length the rod. That is, positioning is required when removing end defects, and the copper rod needs to be moved and positioned again after the end defects are removed. After positioning, the length is cut again. This stage requires repeated movement of the copper rod. In this process, multiple mechanisms or manual labor are required, making the cutting process cumbersome.

[0004] Therefore, it is necessary to develop a more integrated copper cutting equipment that can automatically clamp the copper rod, accurately feed it to a fixed length, and automatically tilt and unload it after cutting in a single cutting cycle. This would simplify the equipment structure, improve cutting accuracy and production efficiency, and meet the dual requirements of copper cutting quality and capacity for the manufacturing of high-voltage wires for new energy vehicles. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the cumbersome copper rod cutting process mentioned above, this invention is proposed.

[0007] Therefore, the purpose of this invention is to provide a copper cutting device for manufacturing high-voltage wires for new energy vehicles.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a copper cutting device for manufacturing high-voltage wires for new energy vehicles, comprising a copper rod, a frame, a transverse movement mechanism, a rotary cutting table, a lifting mechanism, and a rotary cutting mechanism, and further comprising... The transverse mechanism is mounted on the frame and drives the rotary cutting table to move along the axial direction of the copper rod; the rotary cutting mechanism is driven to move up and down by a lifting mechanism. The fastening claw is set on the rotary cutting mechanism. When the rotary cutting mechanism descends, it first contacts the cutting blade and elastically presses the copper rod. The conveying limiting table is set on one side of the frame, which allows the copper rod to move in one direction and restricts its reverse movement, so that when the rotary cutting table is reset, it drives the copper rod to move synchronously to achieve fixed-length feed. The feeding push rod is linked to the up-and-down movement of the rotary cutting mechanism. When the rotary cutting mechanism rises, it lifts the copper rod to tilt it for feeding.

The side facing the copper rod to be cut only serves a fastening function, while the elastic clamping component on the opposite side is linked with the feeding push rod to complete the feeding of the fixed-length copper rod.

[0012] As a preferred embodiment of the copper cutting equipment for manufacturing high-voltage wires for new energy vehicles according to the present invention, wherein: each of the fastening claws is provided with a matching fastening block below it, and the arc surface of the fastening block and the fastening claw is customized according to the size of the copper rod.

[0013] As a preferred embodiment of the copper cutting equipment for manufacturing high-voltage wires for new energy vehicles according to the present invention, the feeding push rod is connected to an elastic inclined block by a spring, and a gear transmission component is installed on the inner wall of the rotating cutting table. The gear transmission component achieves transmission engagement when the feeding push rod moves upward. An upper spring block is embedded below the fastening block. When the feeding push rod moves upward, the gear transmission component drives the upper spring block to move upward and touch the copper rod to tilt.

[0014] As a preferred embodiment of the copper cutting equipment for manufacturing high-voltage wires for new energy vehicles according to the present invention, the gear transmission component includes a helical gear, the inclined surface of the helical gear and the inclined surface of the elastic inclined block are engaged. When the feeding push rod moves down, the inclined surfaces of the two contact each other, and the elastic inclined block retracts into the feeding push rod. When the feeding push rod moves up, the vertical surfaces of the two contact each other, so that the elastic inclined block drives the helical gear to rotate. The helical gear is meshed with meshing teeth, and the meshing teeth are engaged with an L-shaped rod. The L-shaped rod is connected to the bottom of the upper spring block. The bottom of the upper spring block is provided with a restoring spring, and the feeding end of the rotary cutting table is provided with an inclined sliding roller.

The unidirectional rotating roller is firmly attached to the copper rod, which in turn allows the copper rod to move axially toward the cutting end.

[0016] As a preferred embodiment of the copper cutting equipment for manufacturing high-voltage wires for new energy vehicles according to the present invention, wherein: the conveying limiting table is provided with a conveying fastening component inside, which is used to press down and stabilize one side of the copper rod when performing fixed-length cutting.

The elastic clamping design of the fastening claw and the cooperating fastening block ensures that the copper rod is firmly clamped before cutting, effectively suppressing vibration and displacement during the cutting process; at the same time, the unidirectional rotating roller and ratchet in the conveying limiting table cooperate to achieve unidirectional precise feeding of the copper rod, ensuring the cutting accuracy of fixed length. This structure integrates clamping and feeding functions, avoiding the cumulative error caused by multiple clamping and positioning in traditional equipment, significantly improving the cut quality and dimensional consistency, and meeting the strict requirements of high-voltage line terminal crimping for the quality of copper end face. Second, by utilizing the lifting action of the rotary cutting mechanism in conjunction with the unloading push rod, the copper rod is automatically lifted and tilted for unloading during the return stroke after cutting, eliminating the need for an additional independent unloading drive device. Simultaneously, the resetting process of the transverse mechanism drives the copper rod to be fed synchronously to a fixed length, combining the separate feeding and resetting actions in traditional equipment into one. This linkage design simplifies the equipment structure and control logic, shortens the processing cycle of a single piece, and realizes a continuous automated cycle of cutting, unloading, and feeding, significantly improving production efficiency and reducing equipment manufacturing costs.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

[0032] Reference Figures 1-7This embodiment of the invention provides a copper cutting device for manufacturing high-voltage wires for new energy vehicles, including a copper rod 7, a frame 1, a transverse mechanism 11, a rotary cutting table 12, a lifting mechanism 13, and a rotary cutting mechanism 14. The transverse mechanism 11 is mounted on the frame 1 and drives the rotary cutting table 12 to move axially along the copper rod 7. The rotary cutting mechanism 14 is driven to move up and down by the lifting mechanism 13. The rotary cutting mechanism 14 includes a cutting blade 141 and a rotary drive assembly to perform rotary cutting on the copper rod 7. When cutting the copper rod 7, the transverse mechanism 11 moves the rotary cutting table 12 to the initial end of the copper rod 7. At this time, the lifting mechanism 13 drives the rotary cutting mechanism 14 to move downwards. When the rotary cutting mechanism 14 moves downwards, it drives the upper connecting rod 24 to move downwards. The movement of the upper connecting rod 24... The movable allowance spring 23 and guide rod 22 move down, causing the clamping claw 2 to contact the initial end of the copper rod 7. At this time, the rotary cutting mechanism 14 continues to move down, and the movable allowance spring 23 causes the clamping claw 2 to gradually press the copper rod 7. At this time, the rotary cutting mechanism 14 drives the cutting blade 141 to rotate and cut the end of the copper rod 7 (the initial end of the copper rod 7 has defects such as burrs and needs to be cut off a small section). After the cutting is completed, the rotation of the cutting blade 141 stops, but the rotary cutting mechanism 14 does not move up. At this time, the transverse mechanism 11 drives the rotary cutting table 12 to move back to its original position, thereby causing the clamping claw 2 to move with the copper rod 7 clamped by the fastening block 3. The initial cutting surface of the copper rod 7 is the origin, and there is no need to reset the cutting origin. After the rotary cutting table 12 is reset, the rotary cutting mechanism 14 moves up, and the clamping of the copper rod 7 by the clamping claw 2 is also canceled.

[0033] The fastening claw 2, mounted on the rotary cutting mechanism 14, first contacts the cutting blade 141 and elastically presses the copper rod 7 as the rotary cutting mechanism 14 descends. A support guide block 21 is fixedly connected to the support frame of the rotary cutting table 12. A guide rod 22 is movably connected to the support guide block 21. A spare spring 23 is installed at the top of the guide rod 22, and an upper connecting rod 24 is installed at the top of the spare spring 23. The upper connecting rod 24 is fixedly connected to the mounting surface of the rotary cutting mechanism 14 via an extension plate. A space is provided between the upper connecting rod 24 and the support guide block 21. There is a return spring 25; at this time, the rotating cutting table 12 moves to a fixed length, and its rotating cutting blade 141 moves to the cutting point of the copper rod 7. When it reaches the end of the fixed length movement, the rotating cutting table 12 touches the transverse pressure rod 63. The transverse pressure rod 63 moves so that the pressing block 64 presses down the pressing contact rod 62. The pressing contact rod 62 presses down to fasten and press the copper rod 7. At this time, the lifting mechanism 13 drives the rotating cutting mechanism 14 to move down to perform the cutting action, thereby completing the first section of the copper rod 7 cutting action. At this time, the rotating cutting table 12 resets again.

[0034] Specifically, the elastic clamping components, consisting of the fastening claw 2, the support guide block 21, the allowance spring 23, the upper connecting rod 24, and the return spring 25, are arranged in two sets, located on both sides of the cutting surface of the cutting blade 141. The side facing the copper rod 7 to be cut only serves a fastening function, while the elastic clamping component on the opposite side is linked with the unloading push rod 4 to complete the unloading of the fixed-length copper rod 7. At this time, when the lifting mechanism 13 drives the rotating cutting mechanism 14 to move upward, the lifting mechanism 13 drives the unloading push rod 4 to move upward. The unloading push rod 4 drives the helical gear 421 to rotate through the elastic helical gear. The rotation of 21 drives the meshing teeth 422 to rotate, and the rotation of the meshing teeth 422 drives the L-shaped rod 423 to move upward. The upward movement of the L-shaped rod 423 causes the upper spring block 43 to protrude upward at the bottom of the fastening block 3, thereby causing the copper rod 7, which has been cut to a fixed length, to tilt. Then the copper rod 7 slides down through the sliding roller 45 to complete the unloading. When the unloading push rod 4 separates from the helical gear 421, its restoring spring 44 restores the upper spring block 43, so as not to affect the subsequent clamping action. The copper rod 7 repeats the above actions to complete the fixed-length cutting and unloading until the original copper rod 7 is cut.

[0035] Each fastening claw 2 is provided with a matching fastening block 3 below it. The arc surface of the matching fastening block 3 and the fastening claw 2 is customized according to the size of the copper rod 7.

[0036] Furthermore, the conveying limiting table 5 is set on one side of the frame 1, which allows the copper rod 7 to move in one direction and restricts its reverse movement, so that when the rotary cutting table 12 is reset, it drives the copper rod 7 to move synchronously to achieve fixed-length feeding. The conveying limiting table 5 has a through hole 51 inside, which is set according to the size of the copper rod 7. The inner wall of the through hole 51 is provided with a one-way rotating roller 52. The top of the one-way rotating roller 52 is provided with a groove 521. A ratchet 522 is matched above the groove 521. The cooperation between the ratchet 522 and the groove 521 allows the one-way rotating roller 52 to rotate only in one direction. The one-way rotating roller 52 is firmly attached to the copper rod 7, so that the copper rod 7 can only move axially toward the cutting end. Its ratchet 522 is embedded in the inclined groove 521 of the unidirectional rotating roller 52, so that the unidirectional rotating roller 52 can only rotate in one direction, so that the copper rod 7 can only move in one direction on the conveying restriction table 5, so that the fixed-length movement of the rotating cutting table 12 will not touch the copper rod 7 and cause displacement, thereby making the cutting length accurate. The conveying limiting table 5 is equipped with a conveying fastening assembly 6, which is used to press down and stabilize one side of the copper rod 7 during fixed-length cutting. The conveying fastening assembly 6 includes a fastening plate 61 disposed above the through hole 51. A pressing contact rod 62 is installed on the side wall of the fastening plate 61. A pressure-receiving inclined surface is provided on the pressing contact rod 62. A transverse pressure rod 63 is installed at the end of the conveying limiting table 5. A matching pressing block 64 is installed at the embedded end of the transverse pressure rod 63 on the conveying limiting table 5. The matching pressing block 64 is in contact with the pressure-receiving inclined surface of the pressing contact rod 62.

[0037] Furthermore, the feeding push rod 4 is linked to the up and down movement of the rotary cutting mechanism 14. When the rotary cutting mechanism 14 rises, it lifts the copper rod 7 to tilt it for feeding. The feeding push rod 4 is connected to an elastic inclined block 41 by a spring. A gear transmission component 42 is installed on the inner wall of the rotary cutting table 12. The gear transmission component 42 engages when the feeding push rod 4 moves upward. An upper spring block 43 is embedded below the fastening block 3. When the feeding push rod 4 moves upward, the gear transmission component 42 drives the upper spring block 43 to move upward and touch the copper rod 7 to tilt. Furthermore, the gear transmission component 42 includes a helical gear 421, the inclined surface of the helical gear 421 is engaged with the inclined surface of the elastic inclined block 41. When the feeding push rod 4 moves down, the inclined surfaces of the two contact each other, and the elastic inclined block 41 retracts into the feeding push rod 4. When the feeding push rod 4 moves up, the vertical surfaces of the two contact each other, so that the elastic inclined block 41 drives the helical gear 421 to rotate. The helical gear 421 is meshed with meshing teeth 422, and the meshing teeth 422 are engaged with an L-shaped rod 423. The L-shaped rod 423 is connected to the bottom of the upper spring block 43. The bottom of the upper spring block 43 is provided with a restoring spring 44. The feeding end of the rotary cutting table 12 is provided with an inclined sliding roller 45. The rotation of the helical gear 421 drives the meshing gear 422 to rotate, the rotation of the meshing gear 422 drives the L-shaped rod 423 to move, the movement of the L-shaped rod 423 drives the upper spring block 43 to move, thereby tilting and feeding the loose fixed-length copper rod 7.

[0038] Operation process: When cutting the copper rod 7, the horizontal movement mechanism 11 drives the rotary cutting table 12 to move to the initial end side of the copper rod 7. At this time, the lifting mechanism 13 drives the rotary cutting mechanism 14 to move downward. When the rotary cutting mechanism 14 moves downward, it drives the upper connecting rod 24 to move downward. The movement of the upper connecting rod 24 drives the residual spring 23 and the guide rod 22 to move downward, thereby making the fastening claw 2 contact the initial end of the copper rod 7. At this time, the rotary cutting mechanism 14 continues to move downward, and the residual spring 23 makes the fastening claw 2 gradually press the copper rod 7. At this time, the rotary cutting mechanism 14 drives the cutting blade 141 to rotate and cut the end of the copper rod 7 (the initial end of the copper rod 7 has defects such as burrs and needs to be cut off a small section). After cutting, the rotation of the cutting blade 141 stops, but the rotating cutting mechanism 14 does not move. At this time, the transverse mechanism 11 drives the rotating cutting table 12 to move back to its original position, thereby causing the clamping claw 2 to move with the copper rod 7 clamped by the fastening block 3. The initial cutting surface of the copper rod 7 is the origin, and there is no need to reset the cutting origin. After the rotating cutting table 12 is reset, the rotating cutting mechanism 14 moves upward, and the clamping claw 2 on the copper rod 7 is also released. At this time, the rotating cutting table 12 moves to a fixed length (i.e., it moves according to the length of the copper rod 7 to be cut), and the rotating cutting blade 141 moves to the cutting point of the copper rod 7 (during this movement, its ratchet 522 is engaged with the inclined plate of the unidirectional rotating roller 52). Within the groove 521, the unidirectional rotating roller 52 can only rotate in one direction, allowing the copper rod 7 to move only in one direction on the conveying limiting table 5. This ensures that the fixed-length movement of the rotating cutting table 12 will not cause displacement of the copper rod 7, thus ensuring accurate cutting length. At the end of the fixed-length movement, the rotating cutting table 12 touches the transverse pressure bar 63. The movement of the transverse pressure bar 63 causes the pressing block 64 to press down the pressing contact bar 62. The pressing contact bar 62 presses down to firmly press the copper rod 7. At this time, the lifting mechanism 13 drives the rotating cutting mechanism 14 to move down to perform the cutting action, thus completing the first stage of copper rod 7 cutting action. Then, the rotating cutting table 12 resets, and the lifting mechanism 13 drives the rotating cutting mechanism 14 to move up. At that time, its lifting mechanism 13 drives the unloading push rod 4 to move upward. The unloading push rod 4 drives the helical gear 421 to rotate through the elastic helical gear. The rotation of the helical gear 421 drives the meshing gear 422 to rotate. The rotation of the meshing gear 422 drives the L-shaped rod 423 to move upward. The upward movement of the L-shaped rod 423 causes the upper spring block 43 to protrude upward at the bottom of the fastening block 3, thereby causing the copper rod 7, which has been cut to a fixed length, to tilt. Then the copper rod 7 slides down through the sliding roller 45 to complete the unloading. When the unloading push rod 4 separates from the helical gear 421, its restoring spring 44 restores the upper spring block 43, so as not to affect the subsequent clamping action. The copper rod 7 repeats the above action to complete the fixed length cutting and unloading until the original copper rod 7 is cut.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
