Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically to a shearing and edge-rolling device for metal product processing. Background Technology

[0002] Metal products refer to various products made from metal as the main raw material through a series of processing techniques and technologies. Shearing and edge rolling are important steps in metal processing. Shearing is mainly used to cut metal materials to predetermined dimensions, while edge rolling is mainly used to roll the edges of metal materials to improve their strength and aesthetics.

[0003] Currently used edge-rolling equipment requires manual loading and unloading during the product processing. Furthermore, the equipment experiences downtime during loading and unloading, which reduces the edge-rolling processing efficiency.

[0004] The prior art proposes a Chinese patent with publication number CN220880091U to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a metal product processing edge rolling device, including a device base, a worktable is provided at the upper end of the device base, a first gear is connected to the lower end of the worktable, a second gear is provided on the side of the first gear, and a first motor is connected to the lower end of the second gear. This invention, by setting up a worktable, base, first gear, second gear, second motor, lead screw, connecting plate, slide groove, slider, button, insert rod, kit, locking block, locking groove, spring, and pull ring, enables the edge-rolling equipment to complete the unloading and reloading operations of the rolled products during the edge-rolling process. The equipment does not experience downtime due to loading and unloading during processing, thus improving the edge-rolling efficiency. Furthermore, during the unloading operation of the rolled products, simply pulling the pull ring removes the kit and the corresponding product. The structure is simple and unloading is convenient. However, while the above solution uses the kit and its cooperating structure to limit the workpiece, these cannot be adjusted, making it inconvenient to limit metal products of different diameters. This limits the range of shearing and edge-rolling, thus having certain limitations. Utility Model Content

[0005] The purpose of this utility model is to provide a shearing and edge-rolling device for metal product processing, in order to solve the problem that the proposed solution in the background art uses a kit and a matching structure to limit the workpiece, but these cannot be adjusted, making it inconvenient to limit metal products of different diameters, thus limiting the range of shearing and edge-rolling and having certain limitations.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A shearing and edge-rolling device for processing metal products includes a worktable; an adjustment plate is connected to the top of the worktable; an edge-rolling rod is slidably mounted on the top of the worktable on one side of the adjustment plate via an electric push rod two; a cutter is slidably connected to the top of the worktable on the other side of the adjustment plate via an electric push rod one; a controller is fixedly mounted on the top of the worktable at one end of the electric push rod two; a slide plate is slidably mounted on the bottom of the worktable via a hydraulic rod two, and the top of the slide plate is fixedly connected to the surface of the electric push rod two; a movable plate is slidably mounted on the bottom of the worktable on one side of the hydraulic rod two via a hydraulic rod one, and the top of the movable plate is fixedly connected to the surface of the electric push rod one; several screws are rotatably mounted on the interior of the adjustment plate along the circumferential direction via bearings; a slider is threadedly connected to the outer surface of each screw; the top of each slider extends out of the interior of the adjustment plate and is fixedly mounted with a support column; a workpiece is placed on the top of the adjustment plate, and the workpiece is in contact with the top and outer surface of each support column; a fixed frame is slidably mounted on the top of the worktable at the other end of the adjustment plate via a hydraulic cylinder; a pressure plate is rotatably mounted on the bottom of the fixed frame; a motor is fixedly mounted on the top of the fixed frame, and the output shaft of the motor is fixedly connected to the top of the pressure plate.

[0008] The solutions proposed in the background art use kits and matching structures to limit the workpiece, but these cannot be adjusted, making it inconvenient to limit metal products of different diameters, thus limiting the range of shearing and curling. In this application, by rotating each screw separately, the slider slides along the inside of the adjustment disc, which guides and limits the sliding trajectory of the support column, thereby adjusting the movement of the support column to accommodate workpieces of different diameters. After adjustment, it can ensure that the outer surface of each support column fits against the inner wall of workpieces of different diameters, thereby limiting the workpiece and expanding the application range of the device, facilitating subsequent shearing and curling of metal products.

[0009] A further improvement of the present invention is that a fixing plate is fixedly installed on the top of the adjusting plate, the fixing plate is located between each support column, and a rotating plate is rotatably connected to the top of the fixing plate.

[0010] The above technical solution involves installing a fixed plate and a rotating plate. By rotating the rotating plate relative to the fixed plate, the workpiece can be supported and limited to a certain extent, improving the stability of the workpiece placement. Furthermore, an anti-slip pad is provided on the top surface of the rotating plate, which increases the friction between the workpiece and the rotating plate surface. Therefore, during the rotation of the workpiece driven by the pressure plate, the rotating plate can rotate synchronously with the workpiece, thereby reducing wear on the inner wall of the workpiece and protecting it.

[0011] A further improvement of this utility model is that: a number of ball bearings are rotatably installed on the top of the fixed plate at the bottom of the rotating plate, and the top surface of each ball bearing is in contact with the surface of the rotating plate, and the top surface of the rotating plate is in contact with the inner wall of the workpiece.

[0012] By adopting the above technical solution, the contact area between the fixed plate and the rotating plate is reduced by installing a ball bearing, and the ball bearing can roll with the rotating plate, thereby reducing the wear between the fixed plate and the rotating plate and extending their service life.

[0013] A further improvement of this utility model is that: a number of ball bearings are rotatably installed on the top of each support column, and the top surface of each ball bearing is in contact with the inner wall of the workpiece.

[0014] By adopting the above technical solution, the contact area between the top of the support column and the inner wall of the workpiece can be reduced by installing the second ball bearing, and the second ball bearing can roll along the surface of the workpiece, thereby reducing the wear between the support column and the surface of the workpiece and further improving the protection effect on the workpiece.

[0015] A further improvement of this utility model is that a guide plate is fixedly installed at the bottom of the fixing frame around the motor, and several limiting members are fixedly installed at the top of the pressure plate at the bottom of the guide plate, and each limiting member is rotatably connected to the inner wall of the guide plate.

[0016] By adopting the above technical solution, the contact area between the pressure plate and the fixed frame can be increased by installing limiting components and guide plates, which reduces the possibility of the pressure plate disengaging from the motor output shaft at the bottom and improves the stability of the pressure plate rotation.

[0017] A further improvement of this utility model is that a number of ball bearings are rolled on the bottom of the guide plate, and the bottom of each ball bearing is in contact with the surface of each limiting member.

[0018] By adopting the above technical solution, the contact area between the guide plate and the limiting member can be reduced by installing the ball bearings, and the ball bearings can roll along the surface of the limiting member, thereby reducing the wear between the limiting member and the guide plate and extending their service life.

[0019] A further improvement of this utility model is that: handwheels are provided at both ends and on both sides of the adjustment disc, and each screw extends out of the interior of the adjustment disc and is fixedly connected to each handwheel.

[0020] By adopting the above technical solution, the contact area between the operator's hand and each screw can be increased by installing a handwheel, thereby facilitating the rotation of the screw and adjusting the position of the support column.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a shearing and edge-rolling device for metal product processing. Through the mutual cooperation between the screw and the slider, the support column can be moved and adjusted by rotating each screw to adapt to workpieces of different diameters. After adjustment, it can ensure that the outer surface of each support column is in contact with the inner wall of the workpiece of different diameters, thereby realizing the limiting treatment of the workpiece, thus expanding the application range of the device and facilitating the subsequent shearing and edge-rolling work of metal products.

[0023] 2. This utility model provides a shearing and edge-rolling device for metal product processing. By setting a fixed plate and a rotating plate, the workpiece can be supported and limited to a certain extent, thereby improving the stability of the workpiece placement. In addition, during the process of the pressure plate driving the workpiece to rotate, the rotating plate can rotate synchronously with the workpiece, thereby reducing the wear on the inner wall of the workpiece and protecting the workpiece.

[0024] 3. This utility model provides a shearing and edge-rolling device for metal product processing. Through the cooperation between the limiting component and the guide plate, the contact area between the pressure plate and the fixed frame can be increased, reducing the possibility of the pressure plate separating from the output shaft of the motor at the bottom, thereby improving the stability of the pressure plate rotation.

[0034] The present invention will be further described in detail below with reference to embodiments:

[0035] Example 1

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, this utility model provides a shearing and edge-rolling device for metal product processing, including a worktable 1; an adjustment plate 2 is connected to the top of the worktable 1; an edge-rolling rod 9 is slidably installed on the top of the worktable 1 on one side of the adjustment plate 2 via an electric push rod 8; a cutter 7 is slidably connected to the top of the worktable 1 on the other side of the adjustment plate 2 via an electric push rod 6; a controller 4 is fixedly installed on the top of the worktable 1 at one end of the electric push rod 8; a slide plate 15 is slidably installed on the bottom of the worktable 1 via a hydraulic rod 14, the top of which is fixedly connected to the surface of the electric push rod 8; a movable plate 13 is slidably installed on the bottom of the worktable 1 on one side of the hydraulic rod 14 via a hydraulic rod 12. The top of the adjustment plate 2 is fixedly connected to the surface of the electric push rod 6. Several screws 22 are rotatably installed inside the adjustment plate 2 along the circumferential direction via bearings. Each screw 22 has a slider 21 threadedly connected to its outer surface. The top of each slider 21 extends out of the interior of the adjustment plate 2 and is fixedly installed with a support column 18. A workpiece 10 is placed on the top of the adjustment plate 2. The workpiece 10 is in contact with the top and outer surface of each support column 18. A fixed frame 3 is slidably installed on the top of the worktable 1 at the other end of the adjustment plate 2 via a hydraulic cylinder 27. A pressure plate 5 is rotatably installed on the bottom of the fixed frame 3. A motor 11 is fixedly installed on the top of the fixed frame 3. The output shaft of the motor 11 is fixedly connected to the top of the pressure plate 5.

[0037] In this embodiment, the solution proposed in the background art uses a kit and a matching structure to limit the workpiece 10. However, these cannot be adjusted, making it inconvenient to limit metal products of different diameters, thus limiting the range of shearing and curling. In this application, by rotating each screw 22, the slider 21 slides along the inside of the adjusting plate 2, which guides and limits the sliding trajectory of the support column 18. This allows for the movement and adjustment of the support column 18 to accommodate workpieces 10 of different diameters. After adjustment, it ensures that the outer surface of each support column 18 is in contact with the inner wall of the workpiece 10 of different diameters, thereby limiting the workpiece 10 and expanding the application range of the device, facilitating subsequent shearing and curling of metal products.

[0038] Example 2

[0039] like Figure 4 , Figure 6 and Figure 7 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a fixing plate 16 is fixedly installed on the top of the adjusting plate 2. The fixing plate 16 is located between each support column 18. A rotating plate 17 is rotatably connected to the top of the fixing plate 16. A plurality of ball bearings 19 are rotatably installed on the top of the fixing plate 16 at the bottom of the rotating plate 17. The top surface of each ball bearing 19 is in contact with the surface of the rotating plate 17. The top surface of the rotating plate 17 is in contact with the inner wall of the workpiece 10. A plurality of ball bearings 20 are rotatably installed on the top of each support column 18. The top surface of each ball bearing 20 is in contact with the inner wall of the workpiece 10. A guide plate 25 is fixedly installed at the bottom of the fixing frame 3 around the motor 11. A plurality of limiting members 24 are fixedly installed on the top of the pressure plate 5 at the bottom of the guide plate 25. Each limiting member 24 is rotatably connected to the inner wall of the guide plate 25. A plurality of ball bearings 36 are rotatably installed at the bottom of the guide plate 25. The bottom of each ball bearing 36 is in contact with the surface of each limiting member 24.

[0040] In this embodiment, by installing a fixed plate 16 and a rotating plate 17, the rotating plate 17 can be rotated relative to the fixed plate 16, thus providing support and limiting for the workpiece 10 to a certain extent, improving the stability of the workpiece 10. Furthermore, an anti-slip pad is provided on the top surface of the rotating plate 17, increasing the friction between the workpiece 10 and the surface of the rotating plate 17. Therefore, during the rotation of the workpiece 10 driven by the pressure plate 5, the rotating plate 17 can rotate synchronously with the workpiece 10, thereby reducing wear on the inner wall of the workpiece 10 and protecting it. The installation of ball bearings 19 reduces the contact area between the fixed plate 16 and the rotating plate 17, and the ball bearings 19 can roll along with the rotating plate 17, further reducing wear between the fixed plate 16 and the rotating plate 17 and extending their service life. The lifespan of the workpiece is improved by installing ball bearing 20, which reduces the contact area between the top of the support column 18 and the inner wall of the workpiece 10, and allows the ball bearing 20 to roll along the surface of the workpiece 10, thereby reducing wear between the support column 18 and the surface of the workpiece 10 and further improving the protection effect on the workpiece 10. The contact area between the pressure plate 5 and the fixed frame 3 is increased by installing the limiting member 24 and the guide plate 25, which reduces the possibility of the pressure plate 5 disengaging from the output shaft of the motor 11 at the bottom and improves the stability of the rotation of the pressure plate 5. The contact area between the guide plate 25 and the limiting member 24 is reduced by installing ball bearing 26, and the ball bearing 26 can roll along the surface of the limiting member 24, thereby reducing wear between the limiting member 24 and the guide plate 25 and extending their service life.

[0041] Example 3

[0042] like Figure 1 , Figure 4 and Figure 5 As shown, based on Embodiment 2, this utility model provides a technical solution: preferably, handwheels 23 are provided at both ends and on both sides of the adjustment disk 2, and each screw 22 extends out of the interior of the adjustment disk 2 and is fixedly connected to each handwheel 23 respectively.

[0043] In this embodiment, by installing the handwheel 23, the contact area between the operator's hand and each screw 22 can be increased, thereby facilitating the rotation of the screw 22 to adjust the position of the support column 18.

[0044] The working principle of this metal product processing shearing and edge-rolling equipment is explained in detail below.

[0045] like Figures 1-7As shown, depending on the actual diameter of different workpieces 10, the operator can rotate each screw 22, simultaneously driving the slider 21 to slide along the inside of the adjusting plate 2, thereby adjusting the movement of the support column 18. After adjustment, ensure that the outer surface of each support column 18 is in contact with the inner wall of the workpiece 10 to achieve the limiting treatment of the workpiece 10. After the inner wall of the workpiece 10 is in contact with the top of each support column 18 and the rotating plate 17, the operator uses the hydraulic cylinder 27 to drive the fixed frame 3 to move to the bottom, so that the bottom of the pressure plate 5 is in contact with the surface of the workpiece 10 to limit the workpiece 10. Then, the motor 11 drives the pressure plate 5 to rotate, simultaneously driving the workpiece 10 to rotate. At this time, the rotating plate... 17 and each of the two ball bearings 20 can rotate synchronously with the workpiece 10. Depending on the cutting requirements, the operator can use the electric push rod 6 to move the cutter 7 to the top or bottom to adjust the height of the cutter 7. Then, the hydraulic rod 12 is used to move the movable plate 13 to one side, so that the cutter 7 is close to the workpiece 10 and cuts the workpiece 10. After the cutting is completed, the operator moves the cutter 7 away from the workpiece 10. Then, as needed, the electric push rod 8 is used to move the edge curling rod 9 to the top or bottom to adjust the height of the edge curling rod 9. Then, the hydraulic rod 14 is used to move the slide plate 15 to the other side, so that the edge curling rod 9 is close to the workpiece 10 and squeezes and curls the workpiece 10, thereby completing the shearing and edge curling work.

[0046] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
