Description

Technical Field

[0001] This utility model belongs to the field of bending tooling technology, and in particular relates to a bending tooling. Background Technology

[0002] With the rapid development of modern manufacturing, especially in industries such as automobiles, aerospace and electronic equipment, the demand for precision sheet metal parts and metal structures has increased dramatically. Bending fixtures, as a core processing equipment, are widely used in the bending and forming process of materials, and their performance directly determines the dimensional accuracy, surface quality and overall reliability of the products.

[0003] However, existing bending fixtures are not convenient for limiting the workpiece during bending. The workpiece is prone to lateral slippage and displacement when subjected to force during bending, which leads to a decrease in the stability of the bending position and thus affects the bending quality. Utility Model Content

[0004] The purpose of this utility model is to provide a bending fixture that solves the problem that existing bending fixtures are not convenient for limiting the workpiece during bending, and the workpiece is prone to lateral slippage when subjected to force during bending, which leads to a decrease in bending position stability and thus affects bending quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a bending fixture, comprising a hollow support plate, and further comprising: a support portion disposed on the hollow support plate; an anti-slip portion mounted on the hollow support plate; a bending portion disposed on the top of the hollow support plate; the anti-slip portion comprising two centering components, both of which are disposed on the hollow support plate; and a driving component mounted on the hollow support plate; the centering component comprising a hinge rod disposed within the hollow support plate, the top of which is hinged to a rectangular rod, the top of which is fixedly connected to... There are two supports, each with a plurality of rotating shafts fixedly connected to it. The outer walls of each rotating shaft are rotatably connected to a plurality of rollers. A guide is provided on the top of the hollow support plate. The plurality of rotating shafts are arranged in a linear array on the two supports. The guide includes two rectangular frames fixedly connected to the top of the hollow support plate. The inner walls of the two rectangular frames are slidably connected to the outer walls of the two supports. Two protective covers are fixedly connected to the outer walls of the two supports. The protective covers are fixedly connected to the inner walls of the two rectangular frames on the side furthest from the two supports.

[0006] Furthermore, the drive assembly includes a motor fixedly connected to the bottom of the hollow support plate, the output shaft of the motor being fixedly connected to a second rotating shaft via a coupling, and a second hinge rod being fixedly connected to the outer wall of the second rotating shaft, the second hinge rod being hinged to the first hinge rod; the second rotating shaft is rotatably connected to the hollow support plate.

[0007] Furthermore, the support portion includes several support legs fixedly connected to the bottom of the hollow support plate; the support legs are arranged in a circumferential array of four.

[0008] Furthermore, the bending section includes a bending assembly disposed on the top of the hollow support plate; and a guide assembly disposed above the hollow support plate. The bending assembly includes a U-shaped frame fixedly connected to the top of the hollow support plate, a hydraulic cylinder fixedly connected to the top of the U-shaped frame, the output shaft of the hydraulic cylinder being slidably connected to the hollow support plate, an upper bending block fixedly connected to the output shaft of the hydraulic cylinder, and a lower bending block fixedly connected to the top of the hollow support plate; the upper bending block is located above and adapted to the lower bending block.

[0009] Furthermore, the guide assembly includes two guide rods slidably connected to the U-shaped frame, the bottom of each guide rod being fixedly connected to the upper bending block, and the top of each guide rod being fixedly connected to an anti-detachment block.

[0010] This utility model has the following beneficial effects: 1. By setting up an anti-slip part, after the drive component of the anti-slip part is started, the motor output shaft drives the rotating shaft two to rotate through the coupling. The rotating shaft two drives the hinge rod two to move. The hinge rod two pulls the two hinge rods one through the hinge cooperation, which in turn drives the two rectangular rods to move closer to each other. The rectangular rods drive the corresponding brackets to move closer synchronously under the guidance of the rectangular frame, so that the roller connected to the rotating shaft one on the bracket contacts the workpiece to be bent and achieves centering positioning. After bending is completed, the motor reverses, the drive component drives each component to move in the opposite direction, and the brackets move away from each other and reset. The automatic centering positioning of the workpiece is achieved through mechanical transmission. The rotation design of the roller does not affect the adjustment of the workpiece bending position, and can form a stable limit on the workpiece during the bending process, effectively preventing the workpiece from sliding and deviating, and ensuring the stability of the bending position. 2. By setting up a bending section, after the workpiece is centered and positioned, the hydraulic cylinder at the top of the U-shaped frame is activated, and its output shaft extends, driving the upper bending block to move downwards. This block cooperates with the lower bending block at the top of the hollow support plate to perform a bending operation on the workpiece located between them. During this process, the two guide rods of the guide component slide synchronously with the upper bending block, providing guidance for its movement. The anti-detachment block prevents the guide rods from falling off the U-shaped frame. After bending is completed, the hydraulic cylinder output shaft retracts, driving the upper bending block to reset. The hydraulic cylinder provides stable and sufficient bending power to ensure the workpiece is formed. The guide component ensures the linearity of the upper bending block's movement, preventing it from deviating during bending, thereby ensuring the consistency of the bending angle and the processing quality of the workpiece.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The support part 1 includes a plurality of support legs 112 fixedly connected to the bottom of the hollow support plate 111; the support legs 112 are arranged in a circumferential array of four.

[0017] The anti-slip part 2 includes two centering components 21, both of which are mounted on the hollow support plate 111; and a drive component 22, which is mounted on the hollow support plate 111. Each centering component 21 includes a hinge rod 211 within the hollow support plate 111. A rectangular rod 212 is hinged to the top of the hinge rod 211. Two supports 213 are fixedly connected to the top of the rectangular rod 212. Several rotating shafts 214 are fixedly connected to each of the two supports 213. Several rollers 215 are rotatably connected to the outer walls of the rotating shafts 214. A guide is provided on the top of the hollow support plate 111. The rotating shafts 214 are arranged in a linear array on the two supports 213. The guide includes two rectangular frames 216 fixedly connected to the top of the hollow support plate 111. The inner walls of the two rectangular frames 216 are slidably connected to the outer walls of the two supports 213, and the outer walls of the two supports 213 are fixedly connected to two protective covers 217. Several protective covers 217 are fixedly connected to the inner walls of the two rectangular frames 216 on the side away from the two supports 213. The drive assembly 22 includes a motor 221 fixedly connected to the bottom of the hollow support plate 111. The output shaft of the motor 221 is fixedly connected to a rotating shaft 222 via a coupling. The outer wall of the rotating shaft 222 is fixedly connected to a hinge rod 223, which is hinged to the hinge rod 211. The rotating shaft 222 is rotatably connected to the hollow support plate 111. By setting the anti-slip part 2, a stable limit can be formed on the workpiece during the bending process, effectively preventing the workpiece from slipping and deviating, and ensuring the stability of the bending position.

[0018] The bending section 3 includes a bending assembly 31, which is disposed on the top of the hollow support plate 111; and a guide assembly 32, which is disposed above the hollow support plate 111. The bending assembly 31 includes a U-shaped frame 311 fixedly connected to the top of the hollow support plate 111, a hydraulic cylinder 312 fixedly connected to the top of the U-shaped frame 311, the output shaft of the hydraulic cylinder 312 being slidably connected to the hollow support plate 111, and an upper bending block 313 fixedly connected to the output shaft of the hydraulic cylinder 312. The top of component 1 is fixedly connected to a lower bending block 314; the upper bending block 313 is located above and adapted to the lower bending block 314. The guide assembly 32 includes two guide rods 321 slidably connected to the U-shaped frame 311. The bottom of the two guide rods 321 is fixedly connected to the upper bending block 313, and the top of the two guide rods 321 is fixedly connected to an anti-detachment block 322. By setting the bending part 3, the hydraulic cylinder 312 provides stable and sufficient bending power to ensure the workpiece is formed and to guarantee the processing quality of the workpiece.

[0019] It should be noted that the control of the motor 221 and the hydraulic cylinder 312 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC. The hydraulic cylinder 312 is equipped with a corresponding hydraulic pump to provide power to it.

[0020] A specific application of this embodiment is as follows: In use, the strip block to be bent is placed on top of the lower bending block 314, positioning it between the supports 213 on both sides. The motor 221 is turned on, and the output shaft of the motor 221 drives the rotating shaft 222 to rotate. The rotating shaft 222 drives the hinge rod 223 to move. The hinge rod 223 pulls the two rectangular rods 212 closer together through the two hinge rods 211. The two rectangular rods 212 respectively pull the corresponding two supports 213 closer together under the guidance of the rectangular frame 216, thereby driving the rollers 215 on both sides to center and position the strip block. Then, the motor 221 is turned off, and the strip block is pushed to the sides. The roller 215 moves upward to the corresponding bending position on the lower bending block 314, which activates the hydraulic cylinder 312. The piston rod output shaft of the hydraulic cylinder 312 extends, driving the upper bending block 313 to move downward along the guide rods 321. This allows it to cooperate with the lower bending block 314 to bend the strip block located on it. Under the limiting action of the rollers 215 on both sides, the strip block remains in a centered state during the bending process, effectively preventing it from slipping. After bending is completed, the control motor 221 reverses, and the drive assembly 22 drives the centering assembly 21 to move in the opposite direction, causing the two side supports 213 to move away from each other and reset. The bent strip block can then be removed.
