Description

Technical Field

[0001] This invention relates to the field of rolling processing technology, and in particular to a copper rolling mill and rolling method for processing surface textures on copper plates. Background Technology

[0002] Copper plates, especially thin strip copper plates, are important basic functional materials and are widely used in fields such as electronics, electrical engineering, communications, new energy, decorative building materials and high-end manufacturing. As downstream applications continue to increase their requirements for product functionality and aesthetics, forming microstructure textures on the surface of copper plates has become a key process for giving materials anti-slip properties, increasing specific surface area, improving coating adhesion, enhancing heat dissipation performance, or achieving specific decorative effects.

[0003] Currently, the conventional processing method for surface textures on copper plates mainly adopts continuous roll forming process. Its typical configuration is to pass the copper material through the roll gap between the embossing roller and the rubber roller arranged opposite each other. The copper plate surface is directly rolled by the pre-engraved pattern on the surface of the embossing roller, causing the metal to plastically flow and fill, thereby forming the desired pattern on the surface of the copper plate. This traditional rolling method is essentially a single-pass forming process. The pattern on the surface of the embossing roller completes the morphology transfer of the copper material surface in one pass.

[0004] However, this existing technology has revealed significant technical limitations in actual production. Due to the fact that the amount of plastic deformation of copper material, especially thin strip, is limited by factors such as rolling pressure, material yield strength, and instantaneous contact arc length during a single rolling process, it is often difficult to obtain a sufficiently clear, full, and uniform texture outline in one go. When the process requires high clarity, high precision, or a specific depth of the pattern, it is necessary to adopt a multi-pass repeated rolling method. That is, the copper material passes through the gap between the embossing roller and the rubber roller multiple times, and the deformation is accumulated step by step to improve the texture forming quality. Since each additional rolling pass requires auxiliary operations such as threading, centering, tension establishment, and winding, the operation is extremely cumbersome, with high energy consumption and labor costs, and it also seriously affects the product production efficiency. Summary of the Invention

[0005] This invention provides a copper rolling mill and rolling method for processing surface textures on copper plates, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A copper rolling mill for processing surface textures on copper plates includes two movable frames arranged in a front-to-back manner, an auxiliary roller and an embossing roller located between the two movable frames and arranged vertically, and a power unit configured in cooperation with each of the movable frames. The embossing roller and the auxiliary roller roll the copper material conveyed horizontally between them. The power unit includes a main motor, a worm gear located at the output end of the main motor and parallel to the copper material conveying direction, and a worm wheel meshing with the worm gear. The worm wheel is located on the movable frame and is drivenly connected to the embossing roller. The movable frame and the worm wheel reciprocate along the worm gear axis.

[0007] Furthermore, the copper rolling mill also includes a reversing unit, which is used to transport the copper material that has been rolled on one side back towards the copper material and roll the other side of the copper material.

[0008] Furthermore, there are two auxiliary rollers, located on the upper and lower sides of the embossing roller, respectively, and the rolling processing positions on both sides of the copper material are located on the upper and lower sides of the embossing roller, respectively.

[0009] Furthermore, the embossing roller reciprocates between the two auxiliary rollers and alternately engages with the corresponding auxiliary rollers to roll one side of the copper material.

[0010] Furthermore, the auxiliary roller is an elastic roller, and there are numerous gaps inside the auxiliary roller, which are filled with fluid whose pressure can be adjusted.

[0011] Furthermore, the reversing unit includes a reversing roller one and a reversing roller two arranged opposite to each other, and both the reversing roller one and the reversing roller two are inclined to the embossing roller. When the copper material is conveyed on the reversing roller one or the reversing roller two, the upper and lower surfaces of the copper material exchange positions.

[0012] Furthermore, a slider is vertically slidably mounted on the movable frame, and a support shaft is provided on both the embossing roller and the auxiliary roller. The embossing roller is rotatably mounted on the slider via its support shaft, and the auxiliary roller is rotatably mounted on the movable frame via its support shaft. The copper rolling mill also includes a machine base for supporting a movable frame, a power unit, and a reversing unit. The movable frame is laterally slidably arranged on the reversing unit. A slide block is slidably arranged on the machine base corresponding to the movable frame. The sliding direction of the slide block is consistent with the moving direction of the movable frame. An adjusting shaft is rotatably arranged on the slide block. A worm gear is rotatably arranged on the adjusting shaft. The worm gear is connected to the embossing roller through gear one and gear two. The adjusting shaft is connected to the support shaft on the embossing roller through an adjusting arm.

[0013] Furthermore, a square groove is provided on the side wall of the machine tool corresponding to the movable frame, and a drive column is slidably arranged in the square groove. The drive column is connected to the adjustment shaft through a drive arm. A main shaft is provided in the middle of the square groove, and the main shaft is connected to the drive column through a main arm, and the main arm is slidably arranged on the main shaft.

[0014] Furthermore, the position of the drive arm on the adjustment shaft can be adjusted.

[0015] A rolling method for processing surface textures on copper plates includes the following steps: The distance between the drive column and the adjustment shaft is adjusted by the drive arm, thereby adjusting the gap between the embossing roller and the corresponding auxiliary roller and the amount of deformation of the embossing roller by the copper material pressing the auxiliary roller during the working state; The elastic strength of the auxiliary roller is adjusted by regulating the fluid pressure inside the auxiliary roller. The copper material is passed through the gap between the embossing roller and an auxiliary roller, bypasses the reversing unit, and then passes through the gap between the embossing roller and another auxiliary roller, so that the copper material is in a continuous conveying state. The embossing roller is driven to rotate by a power unit; The main shaft moves the drive column along the square groove track via the main arm. The drive column drives the adjusting shaft and slide to reciprocate laterally, while the adjusting shaft rotates back and forth at a specified angle. The adjusting shaft drives the embossing roller along the square groove track via the adjusting arm, so that the embossing roller alternately cooperates with the two auxiliary rollers and repeatedly rolls the two sides of the copper material.

[0016] The technical solution of this invention can achieve the following technical effects: It effectively solves the problems of low efficiency and cumbersome operation caused by traditional multi-pass processing. By setting up embossing rollers that can reciprocate along the copper material conveying direction, it realizes a processing mode in which multiple roll pressing and rolling are performed on any position on the copper material during a single conveying process. This results in a significant improvement in the clarity of the texture and the forming quality, enabling the copper material to be formed in one step, significantly improving production efficiency, while reducing the frequency of equipment start-up and shutdown, the intensity of manual operation, and the overall operating cost.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 2 As shown, this application provides a copper rolling mill for processing the surface texture of copper plates, including two movable frames 200 distributed in front and behind, an auxiliary roller 202 located between the two movable frames 200 and distributed vertically, an embossing roller 201, and a power unit 300 that is configured to cooperate with each movable frame 200. The embossing roller 201 and the auxiliary roller 202 roll the copper material 100 that is horizontally conveyed between them. The power unit 300 includes a main motor 301, a worm 302 disposed at the output end of the main motor 301 and arranged parallel to the conveying direction of the copper material 100, and a worm wheel 303 meshing with the worm 302. The worm wheel 303 is disposed on the movable frame 200 and is connected to the embossing roller 201 for transmission. The movable frame 200 and the worm wheel 303 reciprocate along the axial direction of the worm 302.

[0023] Specifically, both the embossing roller 201 and the auxiliary roller 202 are rotatably mounted on the movable frame 200, and the gap between the embossing roller 201 and the auxiliary roller 202 is used to insert the copper material 100. When the embossing roller 201 rotates, it can cooperate with the auxiliary roller 202 to roll the surface of the copper material 100. The two movable frames 200 support the two ends of the embossing roller 201 and the two ends of the auxiliary roller 202 from the front and rear sides. Each movable frame 200 is equipped with a power unit 300. In this way, the two power units 300 synchronously drive the two movable frames 200 to move, thereby improving the structural stability of the embossing roller 201 and the auxiliary roller 202. The copper material 100 can be conveyed horizontally and rolled, or the embossing roller 201 and the auxiliary roller 202 can be distributed left and right and the conveying direction of the copper material 100 can be set to a vertical state. The specific arrangement can be determined according to actual needs.

[0024] The main motor 301 can provide power to the worm gear 302. The axis of the worm gear 302 needs to be parallel to the conveying direction of the copper material 100. In this way, when the worm wheel 303 rolls on the worm gear 302, the movement direction of the movable frame 200, the embossing roller 201 and the auxiliary roller 202 are parallel to the conveying direction of the copper material 100, and the worm gear 302 and the worm wheel 303 can always maintain a transmission connection.

[0025] In use, the copper material 100 is passed through the gap between the embossing roller 201 and the auxiliary roller 202. The embossing roller 201 presses the copper material 100 onto the auxiliary roller 202. The main motor 301 is started, and the main motor 301 drives the embossing roller 201 to rotate through the worm 302 and the worm wheel 303. The embossing roller 201 rolls and conveys the copper material 100, creating a specified texture on the surface of the copper material 100. The copper material 100 drives the auxiliary roller 202 to rotate synchronously using friction. When the movable frame 200 and the worm wheel 303 reciprocate along the axis of the worm 302... When in motion, the movable frame 200 can drive the embossing roller 201 and the auxiliary roller 202 to reciprocate synchronously along the conveying direction of the copper material 100. Taking a small section of copper material 100 as an example, when the embossing roller 201 and the auxiliary roller 202 reciprocate, the embossing roller 201 and the auxiliary roller 202 repeatedly roll the small section of copper material 100. With the continuous conveying of the copper material 100, the effect of multiple repeated rolling processing on any position of the copper material 100 conveyed in a single delivery can be achieved, so that the texture on the copper material 100 is quickly formed after multiple rolling processes.

[0026] It should be noted that since the rotation of the embossing roller 201 is mainly driven by the worm 302 and the worm wheel 303, the relative speed between the embossing roller 201 and the copper material 100 when the embossing roller 201 rotates statically is the same as the relative speed between the embossing roller 201 and the copper material 100 when the embossing roller 201 reciprocates along the axis of the worm 302. This ensures that the embossing roller 201 can cooperate with the auxiliary roller 202 to transport the copper material 100 when it repeatedly rolls the copper material 100.

[0027] The technical solution of this invention effectively solves the problems of low efficiency and cumbersome operation caused by traditional multi-pass processing. By using an embossing roller 201 that can reciprocate along the conveying direction of the copper material 100, a processing mode in which multiple roll pressings are performed on any position of the copper material 100 during a single conveying process is realized. This significantly improves the clarity of the texture and the forming quality, enabling the copper material 100 to be formed in one step, significantly improving production efficiency, while reducing the frequency of equipment start-up and shutdown, the intensity of manual operation, and the overall operating cost.

[0028] Furthermore, such as Figure 1 As shown, the copper rolling mill also includes a reversing unit 400, which is used to transport the copper material 100 that has completed one side rolling back toward the copper material 100 and roll the other side of the copper material 100.

[0029] After being rolled by the embossing roller 201 and the auxiliary roller 202, the horizontally conveyed copper material 100 produces a specified pattern on one surface. When the copper material 100 is conveyed to the reversing unit 400, the reversing unit 400 reverses the direction of the copper material 100, causing the copper material 100 to move in the opposite direction toward the embossing roller 201 and be rolled by the embossing roller 201 again. At this time, the embossing roller 201 can roll the other side of the copper material 100, thereby producing a specified pattern on both sides of the copper material 100 and achieving a double-sided rolling processing effect.

[0030] Since the rolling of the texture on the copper material 100 is mainly accomplished by the cooperation of the embossing roller 201 and the auxiliary roller 202, the texture on each side of the copper material 100 can be rolled multiple times based on the reciprocating motion of the embossing roller 201 during the conveying process. At the same time, since single-sided rolling is a stamping process, while traditional double-sided rolling is an extrusion process, the copper material 100 processed by two single-sided rolling processes can effectively reduce the overall dimensional changes and deformation. This method is suitable for scenarios with strict thickness tolerance requirements.

[0031] It should be noted that since the processing of both sides of the copper material 100 is carried out simultaneously, this double-sided processing mode will not affect work efficiency.

[0032] Furthermore, there are two auxiliary rollers 202, located on the upper and lower sides of the embossing roller 201 respectively, and the rolling processing positions on both sides of the copper material 100 are located on the upper and lower sides of the embossing roller 201 respectively.

[0033] like Figure 3 As shown, the two auxiliary rollers 202 cooperate with the upper and lower sides of the embossing roller 201 respectively to form two rolling gaps. When the copper material 100 passes through one rolling gap, a specified pattern is generated on one side of the copper material 100. The reversing unit 400 reverses the transport of the copper material 100, so that the copper material 100 passes through the other rolling gap again. At this time, the specified pattern is also generated on the other side of the copper material 100, thereby realizing the double-sided processing of the copper material 100. At the same time, this method can make the copper material 100 form a return transport path, effectively reducing the space occupation during the processing of the copper material 100.

[0034] In some embodiments, the relative positional relationship between the two auxiliary rollers 202 can also be adjusted arbitrarily, as long as it can create two rolling gaps between them and the embossing roller 201, which can make the equipment more versatile.

[0035] Furthermore, the embossing roller 201 reciprocates between the two auxiliary rollers 202 and alternately cooperates with the corresponding auxiliary rollers 202 to roll one side of the copper material 100.

[0036] Taking two auxiliary rollers 202 located on the upper and lower sides of the embossing roller 201 as an example, when the embossing roller 201 rotates statically, it can cooperate with the two auxiliary rollers 202 at the same time to roll both sides of the copper material 100. When the embossing roller 201 reciprocates, if the embossing roller 201 is still cooperating with the two auxiliary rollers 202 at the same time, then the embossing roller 201 and the copper material 100 on its upper and lower sides will inevitably have a speed difference and cause relative friction. In order to avoid this phenomenon, the embossing roller 201 needs to cooperate with only one auxiliary roller 202 at a time and process one side of the copper material 100. Only in this way can the reciprocating motion requirements of the embossing roller 201 be met.

[0037] Specifically, when the embossing roller 201 cooperates with the upper auxiliary roller 202 to roll the copper material 100, the embossing roller 201 separates from the lower auxiliary roller 202. When the embossing roller 201 cooperates with the lower auxiliary roller 202, it separates from the upper embossing roller 201. In this way, by utilizing the alternating movement of the embossing roller 201 between the two auxiliary rollers 202, the reciprocating motion requirements of the embossing roller 201 along the conveying direction of the copper material 100 can be met, and the rolling processing of both sides of the copper material 100 can be realized.

[0038] For ease of understanding, since the embossing roller 201 reciprocates in both the horizontal and vertical directions, its motion trajectory can be set to a square. That is, when the embossing roller 201 is on the upper side of the square trajectory, it cooperates with the upper auxiliary roller 202 and moves to the left; when the embossing roller 201 is on the lower side of the square trajectory, it cooperates with the lower auxiliary roller 202 and moves to the right. At this time, the upper auxiliary roller 202 moves to the right synchronously, thus satisfying the above processing requirements. Of course, in addition to setting the trajectory to a square, it can also be set to a parallelogram, trapezoid, or other shapes, as long as the motion trajectory of the embossing roller 201 when cooperating with the two auxiliary rollers 202 is linear.

[0039] Furthermore, such as Figure 3 As shown, the auxiliary roller 202 is an elastic roller, and there are gaps densely distributed inside the auxiliary roller 202, which are filled with fluid with adjustable pressure.

[0040] Utilizing the elastic deformability of the auxiliary roller 202, when the embossing roller 201 presses the copper material 100 onto the auxiliary roller 202, local deformation will occur in the auxiliary roller 202. At this time, the auxiliary roller 202 and the copper material 100 are in surface contact. At the same time, the auxiliary roller 202 will bend a local part of the copper material 100, giving it a certain curvature. This position of the copper material 100 will adhere to the embossing roller 201, so that the embossing roller 201 and the copper material 100 are also in surface contact. This avoids stress concentration and improves the uniformity of the rolling of the copper material 100.

[0041] The gap inside the auxiliary roller 202 can be filled with fluid, such as hydraulic oil or air. Using this fluid, when the auxiliary roller 202 is deformed by extrusion, the local pressure it receives can be transferred to the entire auxiliary roller 202, thereby facilitating the dispersion of force. At the same time, by adjusting the fluid pressure, the hardness of the auxiliary roller 202 can be adjusted, that is, the amount of deformation of the auxiliary roller 202 when subjected to extrusion force can be adjusted. This makes it convenient to adjust the processing mode according to the hardness and thickness of the copper material 100.

[0042] Furthermore, the reversing unit 400 includes a reversing roller 1 401 and a reversing roller 2 402 arranged opposite to each other, and both the reversing roller 1 401 and the reversing roller 2 402 are inclined to the embossing roller 201. When the copper material 100 is conveyed on the reversing roller 1 401 or the reversing roller 2 402, the upper and lower surfaces of the copper material 100 exchange positions.

[0043] like Figure 4As shown, the reversing roller 1 401 and the reversing roller 2 402 are staggered in the vertical direction. In the horizontal direction, the reversing roller 1 401 and the reversing roller 2 402 are opposite each other, and their included angles with the embossing roller 201 are equal. In this way, when the copper material 100 passes around the reversing roller 1 401, the position of the upper and lower surfaces of the copper material 100 changes. When the copper material 100 passes around the reversing roller 2 402, the upper and lower surfaces of the copper material 100 change again, and the copper material 100 is conveyed in the opposite direction towards the embossing roller 201. At this time, the finished texture on the copper material 100 faces down, and the unprocessed surface of the copper material 100 faces up. When the copper material 100 passes through the embossing roller 201 again, the embossing roller 201 rolls the unprocessed surface of the copper material 100. This structure can be matched with the rotation direction of the upper and lower sides of the embossing roller 201.

[0044] Furthermore, a slider 204 is vertically slidably mounted on the movable frame 200, and a support shaft 203 is provided on both the embossing roller 201 and the auxiliary roller 202. The embossing roller 201 is rotatably mounted on the slider 204 via its support shaft 203, and the auxiliary roller 202 is rotatably mounted on the movable frame 200 via its support shaft 203. The copper rolling mill also includes a machine base 600 for supporting the movable frame 200, the power unit 300, and the reversing unit 400. The movable frame 200 is laterally slidably arranged on the reversing unit 400. A slide block 504 is slidably arranged on the machine base 600 corresponding to the movable frame 200. The sliding direction of the slide block 504 is the same as the moving direction of the movable frame 200. An adjusting shaft 500 is rotatably arranged on the slide block 504. A worm gear 303 is rotatably arranged on the adjusting shaft 500. The worm gear 303 is connected to the embossing roller 201 through a gear 1 501 and a gear 2 502. The adjusting shaft 500 is connected to the support shaft 203 on the embossing roller 201 through an adjusting arm 503.

[0045] like Figure 1 , Figure 2 and Figure 5 As shown, the movable frame 200 can slide laterally on the machine base 600, and the machine base 600 supports the movable frame 200. Since the embossing roller 201 moves in the vertical direction, the embossing roller 201 can be installed on the movable frame 200 through the slider 204. The support shaft 203 can provide support for the corresponding embossing roller 201 or auxiliary roller 202. A cavity can be provided in the middle of the support shaft 203 on the auxiliary roller 202. The cavity is connected to the gap in the auxiliary roller 202, which facilitates the connection between the gap in the auxiliary roller 202 and the external pump body.

[0046] The slide block 504 supports the adjusting shaft 500, worm gear 303, gear one 501, gear two 502, adjusting arm 503, and embossing roller 201. Gear one 501 is coaxially arranged and relatively fixed with worm gear 303. Gear two 502 is installed at the end of the support shaft 203 on the embossing roller 201 and is connected to gear one 501. The adjusting arm 503 is fixedly connected to the adjusting shaft 500 and rotatably connected to the support shaft 203 on the embossing roller 201. The main motor 301 drives the worm gear 303 to rotate through the worm 302. The worm gear 303 drives gear one 501 to rotate and drives the embossing roller 201 and its support shaft 203 to rotate through gear two 502, thereby providing rotational power to the embossing roller 201. When the slide 504 moves laterally on the machine base 600, it drives the embossing roller 201 to move laterally synchronously through the adjusting shaft 500 and the adjusting arm 503. At this time, the worm gear 303 rolls on the worm 302, and the worm 302 always transmits power to the worm gear 303. When the adjusting shaft 504 rotates on the slide 504, the adjusting shaft 500 drives the embossing roller 201 to move in an arc around the axis of the adjusting shaft 500 through the adjusting arm 503, thereby adjusting the vertical height position of the embossing roller 201, so that the embossing roller 201 can move between the two auxiliary rollers 202. At the same time, the embossing roller 201 drives the second gear 502 to move around the first gear 501 through its upper support shaft 203. The second gear 502 and the first gear 501 always maintain a meshing state.

[0047] Furthermore, a square groove 505 is provided on the side wall of the machine tool 600 corresponding to the movable frame 200. A drive column 506 is slidably arranged in the square groove 505. The drive column 506 is connected to the adjustment shaft 500 through a drive arm 507. A main shaft 508 is provided in the middle of the square groove 505. The main shaft 508 is connected to the drive column 506 through a main arm 509, and the main arm 509 is slidably arranged on the main shaft 508.

[0048] like Figure 5As shown, the main shaft 508 can be powered by a drive motor mounted on the machine base 600. The square groove 505 is located outside the movable area of ​​the slide 504, and the horizontal plane of the movable area of ​​the slide 504 is located in the middle of the square groove 505. When the main shaft 508 moves the drive column 506 to the left and right sides of the square groove 505 via the main arm 509, the drive column 506 is displaced in the vertical direction. At this time, the drive column 506 moves the adjusting shaft 500 to rotate via the drive arm 507, thereby adjusting the vertical position of the embossing roller 201. When the moving column 506 moves horizontally on the upper and lower sides of the square groove 505, the slide block 504 and the embossing roller 201 move horizontally. At this time, the movable frame 200 and its worm gear 303 and auxiliary roller 202 move synchronously. Thus, the driving column 506 makes continuous circular motion around the square groove 505, thereby driving the embossing roller 201 to reciprocate in both the horizontal and vertical directions. During the movement of the driving column 506, the distance between it and the main shaft 508 changes constantly, so the main arm 509 needs to be set to slide relative to the main shaft 508.

[0049] Furthermore, the position of the drive arm 507 on the adjustment shaft 500 is adjustable.

[0050] When adjusting the gap between the embossing roller 201 and the auxiliary roller 202, or when adjusting the pressing force of the embossing roller 201 on the copper material 100, the vertical range of motion of the embossing roller 201 can be adjusted. That is, the distance between the drive column 506 and the adjustment shaft 500 can be adjusted by adjusting the position of the drive arm 507 on the adjustment shaft 500. After the adjustment is completed, the drive arm 507 and the adjustment shaft 500 can be fixedly connected by fasteners such as set screws and bolts.

[0051] A rolling method for processing surface textures on copper plates includes the following steps: The distance between the drive column 506 and the adjustment shaft 500 is adjusted by the drive arm 507, thereby adjusting the gap size between the embossing roller 201 and the corresponding auxiliary roller 202 and the amount of deformation of the embossing roller 201 by the copper material 100 pressing the auxiliary roller 202 in the working state. The elastic strength of the auxiliary roller 202 is adjusted by adjusting the fluid pressure inside the auxiliary roller 202; The copper material 100 is passed through the gap between the embossing roller 201 and an auxiliary roller 202, and then around the reversing unit 400 before passing through the gap between the embossing roller 201 and another auxiliary roller 202, so that the copper material 100 is in a continuous conveying state. The embossing roller 201 is driven to rotate by the power unit 300; The main shaft 508 moves the drive column 506 along the track of the square groove 505 via the main arm 509. The drive column 506 drives the adjusting shaft 500 and the slide block 504 to reciprocate laterally, while the adjusting shaft 500 reciprocates at a specified angle. The adjusting shaft 500 drives the embossing roller 201 along the track of the square groove 505 via the adjusting arm 503, so that the embossing roller 201 alternately cooperates with the two auxiliary rollers 202 and repeatedly rolls the two sides of the copper material 100.

[0052] Using the above rolling method, the processing parameters of copper plates with different materials, thicknesses and textures can be quickly adapted and accurately set, which significantly simplifies the operation process. This method controls the embossing roller 201 to perform compound motion along the set trajectory, so that while maintaining continuous rotation, it can move back and forth along the conveying direction of the copper material 100 and alternately cooperate with the auxiliary rollers 202 on the upper and lower sides. Thus, in the continuous conveying process of the copper material 100, the forming effect of repeated rolling of each area on both sides is achieved, which effectively improves the work efficiency.
