Description

Technical Field

[0001] This utility model relates to the field of hardware parts bending technology, specifically a hardware parts bending device. Background Technology

[0002] Hardware parts refer to various metal components made from metal materials (such as steel, iron, copper, aluminum, and stainless steel) through casting, forging, stamping, cutting, welding, and heat treatment processes. They are widely used in industrial production, machinery manufacturing, building decoration, home life, electronics, and many other fields, and are fundamental components supporting modern industry and daily life.

[0003] In traditional metal parts bending processes, positioning is mostly done manually. However, manual placement of parts is prone to inaccurate positioning, leading to deviations in the bending curvature. Furthermore, parts are easily slipped during bending, causing surface scratches or deformation. Manual adjustment of the bending spacing lacks precision, relies on operator experience, and has poor adaptability to parts with different curvature requirements. Frequent mold changes or parameter adjustments increase labor costs. Therefore, we propose a metal parts bending device. Utility Model Content

[0027] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0028] A bending device for hardware parts includes: a workbench 1, with a threaded groove 2 on the top of the workbench 1, threaded blocks 4 symmetrically slidably installed in the threaded groove 2, a pressure plate 5 fixedly installed on the top of the threaded blocks 4, an L-shaped support frame 6 fixedly installed on the top of the pressure plate 5, a limit plate 7 provided inside the L-shaped support frame 6 and directly above the pressure plate 5, two sliding rods 9 fixedly installed on the top of the limit plate 7, and the top ends of the two sliding rods 9 extending through the L-shaped support frame 6 to the outside and fixedly installed with the same handle 10, and a spring 8 sleeved on the sliding rod 9 and inside the L-shaped support frame 6; a support frame 11, fixedly installed on the top of the workbench 1 and directly above the threaded groove 2, a support plate 13 provided inside the support frame 11, and a pressure head 14 fixedly installed at the bottom of the support plate 13; and a drive assembly. The part is located on the workbench 1 and is used to drive the two threaded blocks 4 to move closer or further apart. First, pull the handle 10 upward to drive the slide bar 9 to rise. The limit plate 7 moves upward and compresses the spring 8. Place the hardware part to be bent between the two pressure plates 5. After releasing the handle 10, the spring 8 returns to its original position. The limit plate 7 presses the part under the action of the elastic force. The two threaded blocks 4 are driven to slide symmetrically along the thread groove 2 through the drive assembly, thereby driving the top pressure plate 5 to move closer or further apart until the preset bending distance is adjusted. During the bending stage, the pressure head 14 contacts the part and applies pressure to bend the part to an arc that matches the distance between the two pressure plates 5. After the bending is completed, the hydraulic cylinder 12 drives the pressure head 14 to rise and reset. The self-locking motor 16 is started in the opposite direction to move the pressure plate 5 away from the part. The processed part can then be taken out from the workbench 1.

[0029] In this embodiment, the driving component includes:

[0030] A bidirectional threaded rod 3 is rotatably installed in a threaded groove 2. One end of the bidirectional threaded rod 3 passes through two threaded blocks 4. A self-locking motor 16 is fixedly installed on one side of the worktable 1. The output end of the self-locking motor 16 extends through one side of the worktable 1 into the threaded groove 2 and is coaxially connected to the bidirectional threaded rod 3. The output shaft of the self-locking motor 16 drives the bidirectional threaded rod 3 in the threaded groove 2 to rotate. The two threaded blocks 4, which are threadedly connected to the bidirectional threaded rod 3, slide symmetrically along the threaded groove 2, causing the top pressure plate 5 to move closer or further away from each other until the preset bending distance is adjusted, after which the self-locking motor 16 locks.

[0031] In this embodiment, the output shaft of the self-locking motor 16 is rotatably connected to the worktable 1 and the bidirectional threaded rod 3. Both threaded blocks 4 are threadedly connected to the bidirectional threaded rod 3, ensuring that the self-locking motor 16 can operate normally on the worktable 1. Under the action of the thread, the rotating bidirectional threaded rod 3 drives the two threaded blocks 4 to move closer to each other or further away from each other.

[0032] In this embodiment, a hydraulic cylinder 12 is fixedly installed on the top of the support frame 11. The output shaft of the hydraulic cylinder 12 passes through the top of the support frame 11 and is coaxially connected to the support plate 13. The output shaft of the hydraulic cylinder 12 is slidably connected to the support frame 11. When the hydraulic cylinder 12 at the top of the support frame 11 is activated, its output shaft pushes the support plate 13 to descend vertically along the support frame 11, ensuring that the hydraulic cylinder 12 can operate normally on the support frame 11.

[0033] In this embodiment, the slide rod 9 is slidably connected to the L-shaped support frame 6, ensuring that the slide rod 9 can slide on the L-shaped support frame 6.

[0034] In this embodiment, the top of the pressure plate 5 is provided with anti-slip texture. The anti-slip texture on the top of the pressure plate 5 enhances the friction and prevents the parts from shifting.

[0035] In this embodiment, support legs 15 are fixedly installed at the bottom of the workbench 1 and near the four corners. Anti-slip pads are fixedly installed at the bottom of the support legs 15. The support legs 15 and the anti-slip pads at the bottom of the workbench 1 ensure the stability of the equipment during operation.

[0036] In this embodiment, the pressure head 14 is located between the two pressure plates 5 to ensure that the pressure head 14 can accurately perform bending operations on the hardware parts between the two pressure plates 5, and avoid pressing off the edge or pressing the pressure plates 5.

[0037] In this embodiment, a hardware bending device is used by first pulling the handle 10 upward to raise the slide bar 9, which in turn moves the limiting plate 7 upward and compresses the spring 8. The hardware part to be bent is placed between the two pressure plates 5. After releasing the handle 10, the spring 8 returns to its original position, and the limiting plate 7 presses the part tightly under the action of elasticity. The anti-slip texture on the top of the pressure plate 5 enhances friction and prevents the part from shifting. When the drive assembly is started, the output shaft of the self-locking motor 16 drives the bidirectional threaded rod 3 in the threaded groove 2 to rotate. The two threaded blocks 4, which are threadedly connected to the bidirectional threaded rod 3, slide symmetrically along the threaded groove 2, causing the top pressure plates 5 to move closer or further apart until the preset bending distance is adjusted, after which the self-locking motor 16 locks.

[0038] During the bending stage, the hydraulic cylinder 12 at the top of the support frame 11 is activated, and its output shaft pushes the support plate 13 to descend vertically along the support frame 11. The bottom pressure head 14 contacts the part and applies pressure, bending the part to an arc that matches the distance between the two pressure plates 5. After bending is completed, the hydraulic cylinder 12 drives the pressure head 14 to rise and reset, and the self-locking motor 16 is started in the opposite direction to move the pressure plate 5 away from the part. The processed part can then be removed from the workbench 1. The support legs 15 at the bottom of the workbench 1 and the bottom anti-slip pad ensure the stability of the equipment during operation.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
