Description

Technical Field

[0001] This utility model belongs to the field of automotive hardware processing technology, and in particular relates to an automotive hardware bending machine. Background Technology

[0002] Automotive hardware refers to various metal parts and related hardware components used in automobile manufacturing, assembly, and repair. These hardware components play a vital role in the automotive industry, involving multiple aspects of automobile structure, function, and decoration. Bending is an important metal forming process in automotive parts manufacturing. Through bending, metal sheets or profiles can be processed into parts with specific angles and shapes according to design requirements.

[0003] Bending automotive hardware requires specialized bending equipment, such as a hardware bending device for hardware production with announcement number CN221602910U. This bending device can be used for bending processing of automotive hardware, but it has some defects and shortcomings that need to be improved: (1) Due to structural design reasons, some existing bending devices can only bend a single workpiece. After each workpiece is bent, a new workpiece needs to be replaced, which reduces the overall work efficiency and cannot meet the bending processing needs of large batches of automotive hardware; (2) Some existing bending devices have poor flexibility and it is difficult to adjust the position of the bending parts at will. When it is necessary to bend a specific part of the automotive hardware workpiece, it can only be disassembled and repositioned and fixed, which is cumbersome; (3) Some existing bending devices adopt an integrated design, and the bending parts are difficult to disassemble at will. After long-term operation, the surface of the bending parts is prone to wear, making it inconvenient to maintain or replace them. Therefore, in view of the above problems, the automotive hardware bending machine provided by this utility model is of great significance. Utility Model Content

A positioning mechanism can fix automotive hardware workpieces in various positioning slots, allowing for simultaneous batch bending of multiple workpieces without frequent workpiece changes, thus significantly improving overall work efficiency and effectively meeting the needs of large-volume automotive hardware bending. A drive motor rotates a lead screw, which, through its interaction with the transmission hole, drives the transmission seat and the entire bending mechanism to move horizontally along the slide, allowing adjustment of the bending roller's position as needed. This eliminates the need for disassembly and reassembly to bend specific parts of the automotive hardware workpiece. The bending roller can be removed from the bending frame by unscrewing the screw, facilitating maintenance or replacement when wear occurs due to prolonged operation. In summary, this invention solves the problems in the prior art.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Please see Figure 1-8As shown, this utility model discloses an automotive hardware bending machine, including a bending table 1. Several support legs 2 are fixedly connected to the bottom of the bending table 1, and a bending groove 3 is opened on the top of the bending table 1. Positioning seats 4 are provided on both sides of the bending groove 3. The positioning seats 4 are fixedly connected to the bending table 1, and several positioning slots 5 are opened on the top of the bending table 1. When bending automotive hardware, the two ends of multiple workpieces can be placed into the corresponding positioning slots 5 respectively. A fixed frame 6 is fixedly connected to the top of the bending table 1. The front of the fixed frame 6 is n-shaped, and a pair of brackets 7 are fixedly connected to the top of the fixed frame 6. Fixed plates 8 are fixedly connected to the inner walls on both sides of the fixed frame 6. A positioning mechanism is provided on the fixed plate 8. A motor 9 is installed on one of the brackets 7. A lead screw 10 is installed at the output end of the motor 9. A sliding groove 11 is opened on the top of the fixed frame 6, and a bending mechanism is provided on the top of the fixed frame 6.

[0034] The positioning mechanism includes a cylinder 12, which is mounted on a fixed plate 8. A lifting plate 13 is fixedly connected to the bottom of the output shaft of the cylinder 12. Several connecting blocks 14 are fixedly connected to the bottom of the lifting plate 13. A positioning block 15 is fixedly connected to the bottom of each connecting block 14. By driving the cylinder 12, the lifting plate 13 and each positioning block 15 can be moved downward together until the positioning block 15 is tightly pressed against the top of the automotive hardware workpiece in the corresponding positioning groove 5. At this time, the pressure applied by the positioning block 15 can firmly fix the automotive hardware workpiece in the positioning groove 5 to prevent the two ends of the automotive hardware workpiece from lifting due to force during the bending process.

[0035] The bending mechanism includes a transmission base 16, with a transmission hole 17 on its surface. The wall of the transmission hole 17 has an internal thread that mates with a lead screw 10. The lead screw 10 passes through and is threaded into the transmission hole 17, and its end is rotatably connected to another bracket 7 via a bearing. A slider 18 is fixedly connected to the bottom of the transmission base 16, and a mounting base 19 is fixedly connected to the bottom of the slider 18. An electric telescopic rod 20 is mounted on the bottom of the mounting base 19, and a bending frame 21 is fixedly connected to the bottom of the output shaft of the electric telescopic rod 20. The bending frame 21 has an n-shaped side and a bending roller 22 is mounted on it. The bending mechanism is driven... The electric telescopic rod 20 can drive the bending frame 21 and bending roller 22 to move downward together until the bending roller 22 contacts the automotive hardware workpiece. At this time, the pressure applied by the bending roller 22 can press the automotive hardware workpiece into the bending groove 3 to achieve the bending effect. During the bending process, the drive motor 9 can drive the lead screw 10 to rotate. When the lead screw 10 rotates, it can drive the transmission seat 16 and the entire bending mechanism to move horizontally and linearly along the slide 11 through the mutual cooperation between the lead screw 10 and the transmission hole 17, so as to adjust the position of the bending roller 22 as needed, so that the designated part of the automotive hardware workpiece can be bent without disassembly and reassembly.

[0036] The positioning grooves 5 are linearly distributed at equal intervals along the top surface of the positioning seat 4. The number of positioning blocks 15 is the same as that of the positioning grooves 5, and each positioning block 15 is located directly above the corresponding positioning groove 5. Each positioning block 15 can extend into the corresponding positioning groove 5 at the same time, so as to fix the automotive hardware workpieces in each positioning groove 5 through the positioning mechanism. When multiple automotive hardware workpieces are fixed in the corresponding positioning grooves 5, multiple automotive hardware workpieces can be batch bent at the same time through the bending mechanism without frequent workpiece replacement, thereby greatly improving the overall work efficiency and effectively meeting the bending processing needs of large batches of automotive hardware.

[0037] Each positioning groove 5 has an anti-slip pad 23 on its bottom surface. The anti-slip pad 23 has a herringbone anti-slip pattern on its surface. The anti-slip pad 23 can be made of elastic materials such as rubber and is fixed by means of glue. When both ends of the automotive hardware workpiece are placed in the positioning groove 5, the anti-slip pattern on the surface of the anti-slip pad 23 can increase the friction between the automotive hardware workpiece and the positioning groove 5, so as to play an anti-slip role and effectively prevent the automotive hardware workpiece from slipping and shifting during the bending process.

[0038] Each positioning block 15 has a buffer pad 24 on its bottom surface. The buffer pad 24 can be made of elastic materials such as sponge and is fixed by means of glue. When the positioning block 15 is attached to the top of the automotive hardware workpiece, the buffer pad 24 can play a buffering and protective role to avoid the top surface of the automotive hardware workpiece from directly contacting the positioning block 15 and causing collision and wear.

[0039] Both the slider 18 and the groove 11 are rectangular, and the thickness of the slider 18 is equal to the width of the groove 11. When adjusting the position of the bending mechanism, the cooperation between the slider 18 and the groove 11 can play a limiting role, so as to improve the stability of the bending mechanism and prevent it from shaking and deviating during movement.

[0040] The bending roller 22 has a groove 25 on its body, and an anti-wear sleeve 26 is fitted inside the groove 25. The width of the anti-wear sleeve 26 is equal to the width of the groove 25. The anti-wear sleeve 26 can be made of elastic material such as silicone and is fixed in the groove 25 by insertion. When the bending roller 22 is used to bend automotive hardware parts, the anti-wear sleeve 26 can play a role in anti-wear protection to reduce the collision and wear caused when the bending roller 22 comes into contact with the automotive hardware parts, thereby extending the service life of the bending roller 22.

[0041] The bending frame 21 has threaded holes 27 on both its front and rear faces. A screw 28 is threaded into the threaded hole 27 and engages with it. The bending roller 22 has threaded grooves 29 on both ends. The diameter of the threaded groove 29 is equal to the diameter of the screw 28, and the inner wall surface of the threaded groove 29 is provided with an internal thread that engages with the screw 28. By tightening the screw 28 in the threaded hole 27, the end of the screw 28 can be screwed into the threaded groove 29. At this time, the bending roller 22 can be fixed on the bending frame 21 through the mutual cooperation between the screw 28, the threaded hole 27, and the threaded groove 29. When the bending roller 22 wears out due to long-term use, the bending roller 22 can be removed from the bending frame 21 by unscrewing the screw 28 for maintenance or replacement.

[0042] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0043] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0044] The working principle of this utility model is as follows:

[0045] In use, this invention allows multiple workpieces to be placed into their respective positioning slots 5 at both ends. Then, the cylinder 12 is driven to move the lifting plate 13, along with each positioning block 15, downwards until the positioning blocks 15 are firmly pressed against the top of the automotive hardware workpiece within the corresponding positioning slot 5. The pressure applied by the positioning blocks 15 securely fixes the automotive hardware workpiece within the positioning slot 5. Next, the electric telescopic rod 20 is driven to move the bending frame 21, along with the bending roller 22, downwards until the bending roller 22 contacts the automotive hardware workpiece. The pressure applied by the bending roller 22 then presses the automotive hardware workpiece into the bending groove 3, achieving a bending effect. When multiple automotive hardware workpieces are fixed in their respective positioning slots 5, they can be bent using the bending mechanism. This system can perform batch bending of multiple automotive hardware parts without frequent workpiece changes, thus greatly improving overall work efficiency and effectively meeting the bending needs of large-volume automotive hardware. During bending, the drive motor 9 can drive the lead screw 10 to rotate. When the lead screw 10 rotates, it can drive the transmission seat 16 and the entire bending mechanism to move horizontally and linearly along the slide groove 11 through the interaction between the lead screw 10 and the transmission hole 17. This allows for adjustment of the position of the bending roller 22 as needed, so that the designated part of the automotive hardware workpiece can be bent without disassembly and reassembly. When the bending roller 22 wears out due to long-term operation, the bending roller 22 can be removed from the bending frame 21 by unscrewing the screw 28 for maintenance or replacement.
