Description

Technical Field

[0001] This utility model relates to the field of hardware processing equipment technology, and in particular to a multi-angle bending device for hardware bending process. Background Technology

[0002] Traditionally, hardware products, also known as small hardware, originally referred to art pieces or metal devices such as knives and swords made from the five metals of gold, silver, copper, iron, and tin through artificial processing. However, with the development of the times and the advancement of technology, the concept of 'hardware' in modern society has been greatly expanded, covering a wider range of fields, including but not limited to hardware tools, hardware components, daily-use hardware, building hardware, and security products.

[0003] Bending is a common step in the production of metal tools, involving the metal sheet undergoing elastic deformation to plastic deformation under a bending machine. However, many existing bending devices only support bending at fixed angles. If bending at different angles is required, the die needs to be changed, which is particularly inconvenient when handling complex workpieces. It may be necessary to change the die multiple times to complete the operation. This process not only reduces production efficiency but also increases production costs.

[0004] Therefore, it is necessary to design a multi-angle bending device for the bending process of hardware parts to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing bending devices that only support fixed-angle bending, the technical problem of this utility model is to provide a multi-angle bending device for the bending process of hardware parts.

[0006] The technical implementation scheme of this utility model is as follows: a multi-angle bending device for hardware bending process, including support legs, worktable, motor, first pointer and positioning block. There are four support legs. The worktable is fixedly connected to the top of the support legs. The motor is fixedly connected to the bottom of the worktable. The first pointer is fixedly connected to the output shaft of the motor. The first pointer points to the scale line on the front side. The positioning block is slidably connected to the front side of the worktable. The positioning block is engaged with the worktable.

[0007] In a preferred embodiment of this utility model, it further includes an L-shaped support plate, a rotating shaft, a connecting block, a first rotating wheel, and a second rotating wheel. The L-shaped support plate is fixedly connected to the middle of the top of the workbench. The rotating shaft is rotatably connected to the bottom of the L-shaped support plate. The connecting block is fixedly connected to the bottom of the rotating shaft. The first rotating wheel is rotatably connected to the right side of the top of the connecting block. The second rotating wheel is rotatably connected to the left side of the first rotating wheel. The left side of the second rotating wheel is smaller than the right side.

[0008] In a preferred embodiment of this utility model, it further includes a bracket, a cylinder, a rack, a gear, and a guide frame. The bracket is fixedly connected to the top left side of the worktable, the cylinder is fixedly connected to the top of the bracket, the rack is fixedly connected to the cylinder extension rod, the gear is fixedly connected to the bottom of the second rotating wheel, the gear and the rack mesh with each other, and the guide frame is fixedly connected to the top of the worktable. There are two guide frames, and the guide frames are located on the right side of the bracket.

[0009] In a preferred embodiment of the present invention, the slide bar, the stop block, the second pointer, and the pin are also included. The slide bar is provided on the right side of the worktable, and the stop block is slidably connected to the slide bar. The second pointer is fixedly connected to the front side of the stop block and points to the right scale line. The pin is slidably connected to the left side of the stop block and engages with the worktable.

[0010] In a preferred embodiment of this utility model, a plurality of holes for the insertion of positioning blocks are provided on the front side of the worktable, and the holes and positioning blocks cooperate with each other.

[0011] In a preferred embodiment of this utility model, a plurality of holes for inserting pins are provided on the right side of the workbench, and the holes and pins cooperate with each other.

[0012] In a preferred embodiment of this utility model, scale lines are provided on both the front and right sides of the worktable.

[0013] The beneficial effects of this utility model are as follows: 1. Through the cooperation of the motor, the first pointer and the positioning block, the output shaft of the motor drives the first pointer to rotate until the first pointer contacts the positioning block, thereby completing the bending at the preset angle. Since the angle of the positioning block is adjustable, the device can realize bending operations at various angles. It can complete the processing of complex workpieces without frequently changing the mold. This not only reduces downtime but also significantly improves production efficiency.

[0014] 2. This utility model utilizes the design of scale lines, a second pointer, and a sliding stop to enable workers to accurately set the bending length. The stop can slide on the slide bar to adapt to different bending length requirements, ensuring that each bend can reach the specified length requirement. This design provides greater flexibility and can meet the processing requirements of different workpieces for bending length. Attached Figure Description

Detailed Implementation

[0021] Example: A multi-angle bending device for hardware bending process, such as... Figure 1 and Figure 2 As shown, it includes support legs 1, worktable 2, motor 3, first pointer 4, and positioning block 5. There are four support legs 1. The top of the support legs 1 is connected to the worktable 2 by screws. The worktable 2 has scale lines on the front and right sides. The motor 3 is fixedly connected to the bottom of the worktable 2. The first pointer 4 is fixedly connected to the output shaft of the motor 3. The first pointer 4 points to the scale line on the front side. The positioning block 5 is slidably connected to the front side of the worktable 2. The front side of the worktable 2 has multiple holes for the positioning block 5 to be inserted. The positioning block 5 is engaged with the worktable 2.

[0022] like Figure 3 As shown, it also includes an L-shaped support plate 6, a rotating shaft 7, a connecting block 8, a first rotating wheel 9, and a second rotating wheel 10. The L-shaped support plate 6 is connected to the top center of the workbench 2 by screws. The bottom of the L-shaped support plate 6 is rotatably connected to the rotating shaft 7. The bottom of the rotating shaft 7 is fixedly connected to the connecting block 8. The top right side of the connecting block 8 is rotatably connected to the first rotating wheel 9. The left side of the first rotating wheel 9 is rotatably connected to the second rotating wheel 10. The left side of the second rotating wheel 10 is smaller than the right side.

[0023] like Figure 4 As shown, it also includes a bracket 11, a cylinder 12, a rack 13, a gear 14, and a guide frame 15. The bracket 11 is connected to the top left side of the worktable 2 by screws. The top of the bracket 11 is connected to the cylinder 12 by screws. The rack 13 is fixedly connected to the telescopic rod of the cylinder 12. The bottom of the second rotating wheel 10 is fixedly connected to the gear 14. The gear 14 and the rack 13 mesh with each other. The top of the worktable 2 is fixedly connected to the guide frame 15. There are two guide frames 15, and the guide frames 15 are located on the right side of the bracket 11.

[0024] like Figure 5As shown, it also includes a slide bar 16, a stop block 17, a second pointer 18, and a pin 19. The slide bar 16 is provided on the right side of the worktable 2, and the stop block 17 is slidably connected to the slide bar 16. The second pointer 18 is fixedly connected to the front side of the stop block 17, and the second pointer 18 points to the right scale line. The pin 19 is slidably connected to the left side of the stop block 17. Multiple holes for the pin 19 to be inserted are opened on the right side of the worktable 2, and the pin 19 is engaged with the worktable 2.

[0025] When it is necessary to bend the hardware, the worker first places the metal material to be bent on the guide frame 15 and lets it pass between the first rotating wheel 9 and the second rotating wheel 10. According to the required bending length, push the metal material until the metal material contacts the stop block 17. After determining the position on the scale line by the second pointer 18, insert the pin 19 to fix the stop block 17.

[0026] Next, the staff can adjust the angle of the positioning block 5 according to the required bending angle. Then, the motor 3 is started. The output shaft of the motor 3 drives the first pointer 4 to rotate. At the same time, the connecting block 8 and the first rotating wheel 9 are driven to rotate through the rotating shaft 7. When the first pointer 4 contacts the positioning block 5, the motor 3 is turned off and stops rotating, completing the bending of the metal material. Then, the cylinder 12 is started. The cylinder 12 pushes the rack 13 forward through the telescopic rod. The rack 13 meshes with the gear 14, thereby driving the gear 14 to rotate. The gear 14 drives the second rotating wheel 10 to rotate. Since the left side of the second rotating wheel 10 is smaller than the right side, when the second rotating wheel 10 rotates 180 degrees, there is a gap between the second rotating wheel 10 and the first rotating wheel 9. At this time, the second rotating wheel 10 and the first rotating wheel 9 will no longer jam the metal material, and the metal material can be taken out, completing the bending of the metal material.
