Description

Technical Field

[0001] The present application belongs to the technical field of plate processing equipment, and more specifically, relates to plate forming and finishing equipment. Background Art

[0002] A cold rolling mill is required when cold rolling is used to manufacture metal sheets. When the width of the metal sheet to be cold rolled is smaller than the length of the cold rolling roller, the metal sheet may deviate left and right, affecting the processing accuracy of the metal sheet.

[0003] To address the above-mentioned issues, Chinese utility model patent publication number CN221909072U discloses a continuous cold-rolling forming device for stainless steel sheet. The device comprises mounting frames that move in opposite directions at equal distances on first and second screws, and positioning wheels disposed on the mounting frames via extension plates. The distance between the positioning wheels on the two mounting frames is adjusted according to the actual width of the stainless steel sheet, thereby limiting the position of the stainless steel sheet on both sides and preventing positional deviation during movement. However, in actual operation, this solution has certain drawbacks. Specifically, due to the weight of the metal sheet, its ends inevitably sag. The thinner the metal sheet, the greater the sag. As a result, the height of the metal sheet on both sides will be lower than the height of the positioning wheels, and the metal sheet will not be fully clamped between the positioning wheels, thus limiting the positioning effect of the positioning wheels. Sometimes, the metal sheet will even interfere with the positioning wheels during movement, hindering its movement. Furthermore, excessive sag in the metal sheet can also affect the deformation effect of cold rolling and affect product precision. Summary of the Invention

[0004] In order to solve the deficiencies of the existing technology, the utility model provides a plate forming and finishing equipment, which can support the metal plate while ensuring that the metal plate is limited on the left and right, thereby preventing the metal plate from sagging excessively and ensuring the processing effect.

[0005] To achieve the above-mentioned purpose, the technical solution of the present application provides a plate forming finishing equipment, comprising a base, a cold rolling roller and a driving motor, support seats are arranged on both sides of the base relative to each other, the cold rolling roller comprises an active roller and a driven roller, the active roller and the driven roller are both rotatably mounted between the two support seats and arranged in parallel up and down, and the output end of the driving motor is transmission-connected to the active roller; a screw rod is mounted between the two support seats, a first thread and a second thread are symmetrically arranged at both ends of the screw rod, the rotation directions of the first thread and the second thread are opposite, and a transmission motor transmission-connected to the screw rod is installed on the base; the outer sides of the first thread and the second thread are both rotationally sleeved with an adjustment frame, the two adjustment frames are provided with extension plates relative to each other, and a limiting wheel is arranged along the extension direction of the extension plate;

[0006] The extension plate is provided with a U-shaped groove. The openings of the U-shaped grooves on the two adjustment frames are positioned opposite each other, with the ends of the U-shaped groove aligned with the gap between the active and passive rollers. A limiting wheel is mounted within the U-shaped groove. Rolling support assemblies are mounted on the upper and lower inner walls of the U-shaped groove, which are designed to roll against the metal sheet. The metal sheet's edges pass through the U-shaped groove, where they are clamped by the rolling support assemblies at both ends to prevent sagging. The metal sheet's edges abut against the limiting wheels to prevent lateral slippage. This arrangement not only ensures the metal sheet is positioned left and right, but also supports its upper and lower sides, preventing excessive sagging when entering the cold rolling rollers and ensuring optimal processing. Furthermore, the rolling support assemblies ensure that the limiting wheels maintain constant contact with the metal sheet, preventing interference and jamming caused by separation. Because the metal sheet rolls against the rolling support assemblies and the limiting wheels, it avoids sliding friction with the outside world, minimizing damage to the metal sheet. By driving the screw rod with a transmission motor, the distance between the two adjustment frames can be adjusted to accommodate metal plates of different widths.

[0007] Optionally, the rolling support assembly includes a ball and a roller support. The outer wall of the roller support is provided with an external thread, and the roller support is screwed through the external thread and installed on the side wall of the U-shaped groove. The end of the roller support located within the U-shaped groove is provided with a cavity, and the ball is placed in the cavity and can rotate. The ball partially extends out of the cavity, and the part of the ball extending out of the cavity is used to abut against the metal sheet. The freely rotating ball abuts against the metal sheet, thereby achieving rolling abutment between the rolling support assembly and the metal sheet. By rotating the roller support, the vertical position of the ball can be adjusted, thereby adjusting the distance between the upper and lower balls to adapt to metal sheets of different thicknesses.

[0008] Optionally, the end of the roller support away from the ball is provided with an outer hexagon or an inner hexagon, so that the vertical position of the ball can be adjusted by rotating the roller support with a wrench.

[0009] Optionally, each extension plate is mounted with a plurality of rolling support assemblies, and the plurality of rolling support assemblies are arranged along the extension direction of the U-shaped groove to ensure the supporting effect.

[0010] Optionally, each adjustment frame is equipped with two extension plates, one on each side of the cold roll. This effectively supports the metal sheet before and after it enters the cold roll, ensuring it is as level as possible before and after the rolls, thus ensuring machining accuracy.

[0011] Optionally, a transverse slide rail arranged in parallel with the screw rod is fixedly connected between the two support seats, and the adjustment frame is slidably arranged on the transverse slide rail. The transverse slide rail can prevent the adjustment frame from rotating along the screw rod, thereby ensuring the stability of the adjustment frame.

[0012] Optionally, the driven roller is located on top of the active roller, with a lead screw motor vertically mounted on the top of each of the two support seats. Both support seats are provided with vertical slides, and the output ends of the two lead screw motors are screwed onto a connecting seat. Both connecting seats are slidably mounted in corresponding vertical slides, and the ends of the driven roller are rotatably mounted on the two connecting seats. The lead screw motor can drive the connecting seat to slide along the vertical slides to adjust the gap between the driven roller and the active roller, thereby adjusting the thickness of the cold-rolled metal sheet.

[0013] Optionally, the top of the vertical chute is open, a mounting plate is bolted to the vertical chute, and the screw motor is fixedly connected to the mounting plate. After the mounting plate bolts are removed, the driven roller, the connecting seat, and the screw motor can be removed from the top of the support base, making disassembly and maintenance easier.

[0014] The technical solution of this application has the following advantages over the prior art:

[0015] During cold rolling, the U-shaped grooves on the extension plate are used to limit the upper and lower and horizontal positions of the metal sheet, which can prevent the metal sheet from sliding horizontally while also preventing it from sagging and vibrating up and down. At the same time, the setting of the rolling support assembly allows the limiting wheel to always be in contact with the metal sheet, avoiding possible interference and jamming due to separation movement. Since the metal sheet is in rolling contact with the rolling support assembly and the limiting wheel, the metal sheet will not generate sliding friction with the outside world, reducing damage to the metal sheet. By driving the screw rod with the transmission motor, the distance between the two adjustment frames can be adjusted to accommodate metal sheets of different widths.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] Example:

[0023] This embodiment provides a plate forming finishing equipment based on Figures 1 to 3 As shown, the cold rolling mill comprises a base 1, cold rolling rollers, and a drive motor 2. Support bases 3 are positioned opposite each other on either side of the base 1. The cold rolling rollers include a driving roller 4 and a driven roller 5. Both the driving roller 4 and the driven roller 5 are rotatably mounted between the two support bases 3 and arranged parallel to each other. The output end of the drive motor 2 is in transmission connection with the driving roller 4. The drive motor 2 drives the driving roller 4 to rotate, and the metal sheet 100 passes between the driving roller 4 and the driven roller 5, completing the cold rolling process. A screw rod 6 is mounted between the two support bases 3. A first thread 7 and a second thread 8 are symmetrically disposed at each end of the screw rod 6, with the first thread 7 and the second thread 8 rotating in opposite directions. A transmission motor 9 is mounted on the base 1 and is in transmission connection with the screw rod 6. Adjustment frames 10 are threadedly mounted on the outer sides of the first and second threads 7 and 8. The two adjustment frames 10 are positioned opposite each other with extension plates 11, and limit wheels 12 are arranged along the extension direction of the extension plates 11. When the transmission motor 9 drives the screw rod 6 to rotate, the adjustment frames 10 on the first and second threads 7 and 8 can move in opposite directions to adjust the distance between the limit wheels 12. The two side edges of the metal plate 100 are respectively in contact with the limiting wheels 12 on the two adjustment frames 10 to prevent the metal plate 100 from sliding sideways. The distance between the limiting wheels 12 is adjusted by the transmission motor 9 to adapt to metal plates 100 of different widths.

[0024] Building on the above structure, the extension plate 11 is provided with a U-shaped groove 13. The openings of the U-shaped grooves 13 on the two adjustment frames 10 are positioned opposite each other. The ends of the U-shaped grooves 13 align with the gap between the driving roller 4 and the driven roller 5. The limiting wheel 12 is mounted within the U-shaped groove 13. The upper and lower inner walls of the U-shaped groove 13 are mounted opposite each other to form a rolling support assembly 14 for rolling contact with the metal sheet 100. During operation, the edges of the metal sheet 100 pass through the U-shaped groove 13 and into the gap between the driving roller 4 and the driven roller 5 for cold rolling. The upper and lower edges of the metal sheet 100 are clamped by the rolling support assembly 14 within the U-shaped groove 13, preventing it from sagging or deforming and ensuring a satisfactory finish. Since the metal sheet 100 is supported on both sides, up and down vibration during operation is avoided, ensuring workpiece stability. Furthermore, the provision of the rolling support assembly 14 ensures that the limiting wheel 12 always contacts the metal sheet 100, preventing interference and jamming caused by separation. Since the metal plate 100 rolls against the rolling support assembly 14 and the limiting wheel 12 , the metal plate 100 does not generate sliding friction with the outside world, thereby reducing damage to the metal plate 100 .

[0025] Further, based on Figure 2 and Figure 3 As shown, the rolling support assembly 14 includes a ball 15 and a roller support 16. The outer wall of the roller support 16 is provided with an external thread, which is screwed through the roller support 16 and installed on the side wall of the U-shaped groove 13. A cavity 17 is provided at the end of the roller support 16 located within the U-shaped groove 13. The ball 15 is positioned within the cavity 17 and is rotatable. The ball 15 partially extends out of the cavity 17, and the portion of the ball 15 extending out of the cavity 17 is used to abut against the metal sheet 100. The freely rotating ball 15 abuts against the metal sheet 100, achieving rolling abutment between the rolling support assembly 14 and the metal sheet 100. By rotating the roller support 16, the vertical position of the ball 15 can be adjusted, thereby adjusting the distance between the upper and lower balls 15 to accommodate metal sheets 100 of varying thickness. In order to facilitate the adjustment of the vertical position of the ball 15 by rotating the roller support 16 with a wrench, an outer hexagonal member 18 or an inner hexagonal member (the inner hexagonal member is not shown in the drawing) may be provided at the end of the roller support 16 away from the ball 15 .

[0026] Further, based on Figure 1 As shown, each extension plate 11 is mounted with several sets of rolling support assemblies 14, for example, three or four sets. Each set of rolling support assemblies 14 comprises two rolling support assemblies 14 arranged in an upper and lower position. The multiple sets of rolling support assemblies 14 are arranged along the extension direction of the U-shaped groove 13 to ensure multiple support points with the metal plate 100, ensuring effective support.

[0027] Each adjustment frame 10 is equipped with two extension plates 11, one on each adjustment frame 10, located on either side of the cold roll. The two sides of the cold roll refer to the side where the metal sheet 100 enters the roll and the side where it exits. The metal sheet 100 is effectively supported both before and after entering the roll, ensuring it is as level as possible before and after the roll, preventing sagging and deformation while ensuring processing accuracy.

[0028] Further, based on Figure 1 As shown, a transverse slide rail 19 is fixedly connected between the two support seats 3 and arranged in parallel with the screw rod 6, and the adjustment frame 10 is slidably arranged on the transverse slide rail 19. The transverse slide rail 19 can prevent the adjustment frame 10 from rotating along the screw rod 6, ensuring the stability of the adjustment frame 10 orientation.

[0029] Further, based on Figure 1 As shown, the driven roller 5 is located on top of the active roller 4. A lead screw motor 20 is vertically mounted on the top of each of the two support seats 3. Both support seats 3 are provided with a vertical slide 21. The output ends of the two lead screw motors 20 are screwed with a connecting seat 22. The two connecting seats 22 are slidably mounted on the corresponding vertical slide 21. The two ends of the driven roller 5 are respectively rotatably mounted on the two connecting seats 22. The lead screw motor 20 can drive the connecting seat 22 to slide along the vertical slide 21 to adjust the gap between the driven roller 5 and the active roller 4, thereby adjusting the cold-rolled thickness of the metal sheet 100. In this embodiment, the top of the vertical slide 21 is open, and a mounting plate 23 is bolted to the vertical slide 21. The lead screw motor 20 is fixedly connected to the mounting plate 23. After the mounting plate 23 is bolted, the driven roller 5, together with the connecting seat 22 and the lead screw motor 20, can be removed from the top of the support seat 3, facilitating disassembly and maintenance.

[0030] The workflow of this embodiment is as follows:

[0031] The distance between the driven roller 5 and the active roller 4 is adjusted by the lead screw motor 20 based on the cold-rolled thickness of the metal sheet 100. The roller supports 16 on each rolling support assembly 14 are rotated to adjust the distance between the rollers of each set of upper and lower roller supports 16 to match the metal sheet 100. The transmission motor 9 adjusts the distance between the two adjustment frames 10 so that the distance between the limiting rollers 12 on the two adjustment frames 10 matches the width of the metal sheet 100. For easier adjustment, the roller supports 16 can be adjusted after the metal sheet 100 is inserted into the U-shaped slot 13.

[0032] The metal sheet 100 is placed on both sides into the U-shaped groove 13 at the feed end of the cold rolling rollers. The metal sheet 100 is restrained in position by the rolling support assembly 14 on the top and bottom, and by the limiting wheels 12 on the left and right sides, to prevent sagging and left-right deviation. The drive motor 2 is activated and pushes the metal sheet 100. Driven by the cold rolling rollers, the metal sheet 100 moves and undergoes the cold rolling process. After cold rolling, the metal sheet 100 is placed on both sides into the U-shaped groove 13 at the discharge end of the cold rolling rollers. The metal sheet 100 is restrained in position by the rolling support assembly 14 on the top and bottom, and by the limiting wheels 12 on the left and right sides.

[0033] After the first metal sheet 100 is processed, the roller support 16 on the discharge side of the cold rolling roller can be adjusted up and down by the processed metal sheet 100 to adapt to the thickness of the processed metal sheet 100. When the metal sheets 100 of the same specification are subsequently processed in batches, the roller support 16 does not need to be repeatedly adjusted.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
