Description

Technical Field

[0001] This utility model relates to the field of bending device technology, specifically a bending device for sheet metal used in rolling mill production. Background Technology

[0002] The rolling mill contains cylindrical workpieces. Rolling mills can be classified into two-roll, four-roll, and six-roll mills according to the number of rolls. Multiple sets of rolls can be arranged in different shapes. After bending, the material plate is fed to the outer wall of the cylindrical workpiece for further processing. In the existing technology, a bending machine is used to perform the corresponding bending operation on the material plate.

[0003] In existing technology, bending machines bend plates by means of a bending seat and a bending head. However, the bending seat only has one set of bending grooves at a fixed angle. This means that the bending seat needs to be replaced when different bending angles of the plate are required. During the replacement process, the bending seat needs to be positioned and fixed multiple times. This increases the overall production cost of the equipment and makes the overall processing steps more complicated. To address the shortcomings of existing technology, we propose a plate bending device for rolling mill production to solve the above problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides a bending device for rolling mill production plates, which solves the problem that when facing bending requirements of different angles of the plate, it is necessary to replace the bending seat. During the replacement process, the bending seat needs to be positioned and fixed multiple times, which increases the overall production cost of the equipment and makes the overall processing steps more complicated. The device enables bending grooves with different opening angles to be opened on the outer wall of the bending seat, and then the bending seat can be rotated to replace the different bending grooves.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses a bending device for sheet metal used in rolling mill production.

[0029] According to the appendix Figure 1-6 As shown, the device includes a bending machine body 1, a support 2 disposed on one side of the bending machine body 1, and a bending head 4 and a bending seat 5 disposed on the inner wall of the bending machine body 1. The bending head 4 is located directly above the bending seat 5. (Refer to the attached diagram.) Figure 6The outer wall of the bending head 4 is provided with a protective layer 41. The protective layer 41 can be made of rubber or other soft materials, so that when the bending head 4 contacts the top of the material plate body 3, no scratches or marks will be left on the surface of the material plate body 3, ensuring the integrity of the surface of the material plate body 3. The material plate body 3 is placed on the top of the support 2, and the bottom of one end of the material plate body 3 abuts against the top of the bending seat 5. The material plate body 3 is mainly used on the rolling mill, which is not specifically shown in the attached drawings. A support plate 8 is provided on one side of the bending machine body 1. A hydraulic cylinder 81 is provided on the top of the support plate 8. A pressure plate 82 is provided at the bottom of the hydraulic cylinder 81 to fix the placement position of the material plate body 3. When the material plate body 3 is bent, the material plate body 3 is bent into place. The plate body 3 is placed on top of the support 2 and pushed along the top of the support 2 towards the bending seat 5 until the end of the plate body 3 to be bent moves to the top of the bending seat 5. Then, the hydraulic cylinder 81 set on one side of the bending machine body 1 is activated, so that the hydraulic cylinder 81 drives the pressure plate 82 to move towards the plate body 3, so that the bottom of the pressure plate 82 abuts against the top of the plate body 3, so that the position of the plate body 3 on the support 2 is fixed. Then, the drive device set inside the bending machine body 1 is activated, so that the bending head 4 moves downward, so that the bending head 4 punches and bends one end of the plate body 3. The angle of the plate body 3 after bending is consistent with the angle of the positioning groove 66 opened on the bending seat 5.

[0030] See attached document Figure 2-4The inner wall of the bending machine body 1 is equipped with a replacement mechanism 6. This mechanism allows for the replacement of bending seats 5 with different bending angles to the processing position, thus meeting the different bending angle requirements of the material plate body 3. The replacement mechanism 6 includes a first movable rod 61. The bending seat 5 is fixedly connected to the outer wall of the first movable rod 61. Multiple sets of positioning grooves 66 are formed on the outer wall of the bending seat 5, with unequal opening angles. A drive motor 62 is located at one end of the first movable rod 61, positioned on one side of a set of fixed boxes 65. The outer wall of the second movable rod 63 is equipped with multiple sets of positioning protrusions 64 that engage with the inner wall of the bending seat 5. The sizes of the positioning protrusions 64 are unequal, and their dimensions match the sizes of the positioning grooves 66. Fixed boxes 65 are located on both sides of the bending machine body 1. The first movable rod 61 and the second movable rod 63... One end of rod 63 is rotatably mounted inside the fixed box 65. A groove 11 is provided on the inner wall of the bending machine body 1. The second movable rod 63 and the positioning protrusions 64 are both rotatably mounted inside the groove 11. When the material plate body 3 needs to be bent at a different angle, the drive motor 62 is first turned on, causing the first movable rod 61 connected to one end of the drive motor 62 to rotate. This causes the bending seat 5 on the outer wall of the first movable rod 61 to rotate along the groove 11 until a set of positioning grooves 66 on the outer wall of the bending seat 5, matching the required bending angle, rotates to the top, meaning the bottom of the material plate body 3 corresponds to the positioning grooves 66. Simultaneously, as the first movable rod 61 drives the bending seat 5 to rotate, multiple sets of positioning protrusions 64, which engage with the bending seat 5, rotate along the second movable rod 63. The rotation direction of the second movable rod 63 is opposite to that of the first movable rod 61. See the attached diagram for details. Figure 3-4 This ensures that a set of corresponding positioning grooves 66 and positioning protrusions 64 are engaged, thereby providing stable support for the position of the bending seat 5 after rotation adjustment. When the bending head 4 performs bending operation on the material plate body 3, the position of the bending seat 5 at the bending machine body 1 will not change.

[0031] See attached document Figure 2 and attached Figure 5 The fixed box 65 is internally equipped with an auxiliary component for assisting in locking the connection position between the positioning protrusion 64 and the bending seat 5. This auxiliary component can fix the positions of multiple positioning protrusions 64 within the groove 11, thereby facilitating stable support of the positioning protrusions 64 for the bending seat 5. The auxiliary component includes a ratchet 7 fixedly mounted on the outer wall of the second movable rod 63, a mounting rod 71 rotatably mounted on the inner wall of the fixed box 65, and a ratchet 72 mounted on the outer wall of the mounting rod 71 that meshes with the ratchet 7. A torsion spring 73 is mounted on the outer wall of the ratchet 72, with one end of the torsion spring 73 connected to the inner wall of the fixed box 65. (Refer to attached diagram). Figure 5When the positioning protrusion 64 rotates clockwise around the second movable rod 63, the ratchet 72 does not obstruct the rotation path of the ratchet 7. When the positioning protrusion 64 rotates counterclockwise around the second movable rod 63, the ratchet 7 cannot rotate, thus preventing the positioning protrusion 64 from changing position. Furthermore, after changing position, the positioning protrusion 64 can achieve self-locking through the cooperation of the ratchet 7 and the ratchet 72. Therefore, referring to the attached... Figure 5 When the drive motor 62 controls the bending seat 5 to rotate counterclockwise around the first movable rod 61, the second movable rod 63 rotates clockwise under the engagement of the positioning protrusion 64 and the positioning groove 66. During this process, the ratchet 72 does not obstruct the rotation path of the ratchet 7. After the bending seat 5 completes the change of the position of the positioning groove 66 at different angles, the fixation of the bending seat 5 by the drive motor 62 is removed. At this time, the ratchet 72 automatically engages with the ratchet 7 under the elastic force of the torsion spring 73, so that the ratchet 7 and the ratchet 72 lock the second movable rod 63 and the fixed box 65, thereby fixing the bending seat 5, which is engaged with the positioning protrusion 64 on the outer wall of the second movable rod 63, on the bending machine body 1.
