Description

Technical Field

[0001] This utility model relates to the field of bending devices, and in particular to a bending device for processing wire groove support frames. Background Technology

[0002] A bending device is a tooling equipment used to plastically process metal sheets, strips or other profiles, causing them to bend and deform at specific locations to obtain the desired shape and angle.

[0003] Existing technologies, such as the utility model patent with publication number CN218361473U, disclose a bending device. This patent employs a conveying mechanism for placing and conveying workpieces to a bending mechanism below it; the bending mechanism includes a bending plate and a rotating motor connected to the bending plate. One side of the bending plate is bent upwards to form an arc-shaped pressing part. The rotating motor drives the pressing part to rotate around the rotating shaft of the motor as its rotation center line. The downward rotating pressing part compresses the workpiece, causing it to form a bent structure. This bending device replaces manual bending operations. The arc-shaped pressing part in the bending mechanism compresses the workpiece through rotation, forming a bent structure, significantly reducing labor intensity and increasing productivity. Furthermore, the bending path of the pressing part is consistent, ensuring that the final bent structure shape and bending angle of each workpiece are uniform, eliminating bending angle deviations and greatly improving the workpiece yield.

[0004] The inventors discovered the following problems in the bending process of the bending device during daily work: In the bending of the wire groove support frame, simple clamps are often used in conjunction with manual bending. This method firstly has the problem of workpiece clamping and fixing: common clamping mechanisms are often cumbersome to operate and have uneven clamping force, which can easily cause the workpiece to loosen or shift during bending, directly affecting the accuracy of the bending angle and position, resulting in defective products; secondly, there is the problem of insufficient precision in controlling the bending dimensions: operation usually relies on the operator's experience to visually inspect or use a ruler to manually measure and position, which is inefficient and makes it difficult to ensure the consistency of bending dimensions of batch products, especially the control of the bending starting point is not precise enough, and it cannot quickly adapt to the processing needs of products with different specifications. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of the existing technology, such as unstable pressing operation and inaccurate bending position.

[0006] To solve the above technical problems, this utility model provides a bending device for processing wire trough support frames, comprising: a tabletop, a plurality of table legs fixedly connected to the lower surface of the tabletop, an adjustment structure provided on the upper surface of the tabletop, the adjustment structure including a bracket, the bracket being fixedly connected to the tabletop, two fixing plates fixedly connected to the upper surface of the bracket, a rotating shaft rotatably connected to the inner walls of the two fixing plates, a first bevel gear fixedly connected to both ends of the rotating shaft, the tooth surfaces of the first bevel gear meshing with a second bevel gear, and the lower surface of the second bevel gear being fixedly connected to... The table is equipped with screws, the upper arc surface of which is rotatably connected to the bracket, and the lower end of which is rotatably connected to the tabletop. Both screws have connecting plates threaded onto their arc surfaces. A pressure frame is fixedly connected to the side of the two connecting plates that is close to each other. A bending plate is rotatably connected to the upper surface of the tabletop at the position corresponding to the pressure frame. A positioning rod is threadedly connected to the side of the bending plate away from the tabletop. A positioning plate is rotatably connected to the end of the positioning rod that is close to the tabletop. A round rod is fixedly connected to the side of the positioning plate that is away from the tabletop. The arc surface of the round rod is slidably connected to the bending plate.

[0007] The aforementioned components achieve the following effects: through simple rotation, the lifting and lowering of both sides of the pressure frame are synchronously controlled, enabling rapid clamping and release of the workpiece, and the positioning plate is used to accurately control the bending position, thereby improving the accuracy and efficiency of bending processing.

[0008] Preferably, a handle is fixedly connected to the arc surface of the rotating shaft, and a plurality of anti-slip protrusions are fixedly connected to the arc surface of the handle.

[0009] The effect achieved by the above components is that by setting a handle with anti-slip protrusions, it provides the operator with a labor-saving and reliable point of force application, preventing the hand from slipping when rotating the shaft, and making the process of adjusting the pressure of the pressure frame smoother and safer.

[0010] Preferably, two protective covers are fixedly connected to the upper surface of the bracket at the position corresponding to the first bevel gear, and the cross-section of the protective covers is rectangular.

[0011] The aforementioned components achieve the following effects: by using a protective cover, the stability and safety of the transmission process are ensured, and the service life of the equipment is extended.

[0012] Preferably, two sliding rods are fixedly connected to the upper surface of the tabletop at the position corresponding to the connecting plate, and the arc surface of the sliding rods is slidably connected to the connecting plate.

[0013] The effect achieved by the above components is as follows: by setting a sliding rod on the table that is slidably connected to the connecting plate, a vertical guide is provided for the up and down movement of the connecting plate and the pressure frame, preventing them from deflecting or shaking when the screw rotates, ensuring that the pressure frame can rise and fall vertically smoothly, thereby uniformly pressing the workpiece and improving the stability of bending quality.

[0014] Preferably, the bent plate has several circular holes on the side away from the tabletop, and a lifting rod is threaded onto the inner wall of one of the circular holes.

[0015] The effect achieved by the above components is that by setting multiple round holes on the bending plate and matching the lifting rod with threaded connection, multiple optional force application points are provided for the operator.

[0016] Preferably, the surface of the round rod is provided with a reserved groove, and the inner wall of the reserved groove is provided with a scale.

[0017] The effect achieved by the above components is as follows: by setting a reserved slot with a scale on the guide rod, the operator can intuitively and accurately read the moving distance of the positioning plate, thereby realizing precise control and rapid setting of the workpiece bending length, greatly reducing the measurement and debugging time, and improving processing accuracy and production efficiency.

[0018] Preferably, a soft pad, which is a rubber pad, is fixedly connected to the inner wall of the tabletop at the position corresponding to the bent plate.

[0019] The effect achieved by the above components is as follows: by setting rubber pads at the contact points between the table and the bending plate, the bending plate can play a buffering and shock-absorbing role when it returns to its original position, avoiding noise and wear caused by direct impact between metal parts. At the same time, it also helps to protect the surface of the bending plate and the table, and extend the service life of the equipment.

[0020] Compared with related technologies, the bending device for processing wire trough support frames provided by this utility model has the following advantages:

[0021] This utility model provides a bending device for processing wire groove support frames. By setting an adjustment structure, a simple rotation operation is performed. The synchronous rotation of the twin screws is achieved through bevel gear transmission, driving the pressure frame to rise and fall smoothly, ensuring that the workpiece is quickly and evenly pressed, effectively preventing displacement during processing. The rotatable bending plate cooperates with the precision-adjustable positioning plate. The position of the positioning plate can be finely adjusted by rotating the positioning rod, thereby precisely limiting the extension length of the workpiece, and ultimately achieving precise control of the bending point. This structure has a high degree of integration, is simple and labor-saving to operate, and significantly improves the consistency and production efficiency of bending processing.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 4The adjustment structure 3 includes a bracket 301, which is fixedly connected to the tabletop 1. Two fixing plates 302 are fixedly connected to the upper surface of the bracket 301. A rotating shaft 303 is rotatably connected to the inner walls of the two fixing plates 302.

A screw 307 is fixedly connected to the lower surface of the second bevel gear 306. The upper arc surface of the screw 307 is rotatably connected to the bracket 301, and the lower end of the screw 307 is rotatably connected to the tabletop 1. Connecting plates 309 are threaded onto the arc surfaces of both screws 307. A pressure frame 310 is fixedly connected to the side of the two connecting plates 309 that is close to each other. The upper surface of the tabletop 1 is positioned corresponding to the pressure frame 310. A bending plate 312 is rotatably connected. A positioning rod 315 is threadedly connected to the side of the bending plate 312 away from the tabletop 1. A positioning plate 316 is rotatably connected to the end of the positioning rod 315 near the tabletop 1. A round rod 317 is fixedly connected to the side of the positioning plate 316 away from the tabletop 1. The arc surface of the round rod 317 is slidably connected to the bending plate 312. Through simple rotation, the lifting and lowering of both sides of the pressure frame 310 are synchronously controlled, achieving rapid clamping and release of the workpiece. The positioning plate 316 accurately controls the bending position, improving the accuracy and efficiency of the bending process. A handle 304 is fixedly connected to the arc surface of the rotating shaft 303. Several anti-slip protrusions are fixedly connected to the arc surface of the handle 304. By setting the handle 304 with anti-slip protrusions, it provides the operator with labor-saving and... A reliable force application point prevents hand slippage when rotating the shaft 303, making the process of adjusting the pressure of the pressure frame 310 smoother and safer. Two protective covers 308 are fixedly connected to the upper surface of the bracket 301 at the position corresponding to the first bevel gear 305. The protective covers 308 have a rectangular cross-section, ensuring the stability and safety of the transmission process and extending the service life of the equipment. Two sliding rods 311 are fixedly connected to the upper surface of the table 1 at the position corresponding to the connecting plate 309. The arc surface of the sliding rods 311 is slidably connected to the connecting plate 309. By setting the sliding rods 311 on the table 1 to slidably connect to the connecting plate 309, vertical guidance is provided for the up-and-down movement of the connecting plate 309 and the pressure frame 310, preventing them from slipping when the screw 307 rotates.

It also helps protect the surfaces of the bending plate 312 and the tabletop 1, extending the service life of the equipment.

[0031] The working principle of the bending device for processing wire groove support frame provided by this utility model is as follows: By setting the adjustment structure 3, rotating the handle 304 causes the rotating shaft 303 to rotate along the fixed plate 302. The rotating shaft 303 then drives the first bevel gears 305 at both ends to rotate. The first bevel gears 305 drive the screw 307 to rotate through the second bevel gear 306. At this time, the screws 307 at both ends of the bracket 301 rotate synchronously. The screws 307 drive the connecting plate 309 to move through the thread. The two connecting plates 309 drive the pressure frame 310 upward away from the table 1. Then, the workpiece to be bent passes through the bracket 301, passes under the pressure frame 310 and enters the bending plate 312 area, and then reverses... Rotating handle 304 causes shaft 303 and screw 307 to rotate in opposite directions, moving pressure frame 310 downwards and pressing the workpiece. Then, rotating bending plate 312 pushes the workpiece to bend. When precise control of the workpiece's bending length is required according to processing needs, first rotate positioning rod 315. Positioning rod 315 moves towards the table 1 via a thread, driving positioning plate 316 to move. During this process, the round rod 317 on positioning plate 316 always slides along bending plate 312, using positioning plate 316 to limit the workpiece's insertion length, thereby controlling the bending length. The handle 304, with its anti-slip protrusions, provides a secure grip for the operator. It provides a labor-saving and reliable force application point, preventing hand slippage when rotating the shaft 303, making the process of adjusting the pressure of the pressure frame 310 smoother and safer. The protective cover 308 ensures the stability and safety of the transmission process and extends the service life of the equipment. By setting a slide rod 311 on the table 1 that is slidably connected to the connecting plate 309, it provides vertical guidance for the up and down movement of the connecting plate 309 and the pressure frame 310, preventing them from deflecting or shaking when the screw 307 rotates, ensuring that the pressure frame 310 can rise and fall vertically smoothly, thereby evenly pressing the workpiece and improving the stability of the bending quality. By setting multiple round holes 313 on the bending plate 312 and matching threaded connections, it ensures that the pressure frame 310 can rise and fall smoothly. The lifting rod 314 provides the operator with multiple selectable force application points. By setting a reserved groove with a scale 318 on the guide rod 317, the operator can intuitively and accurately read the moving distance of the positioning plate 316, thereby achieving precise control and rapid setting of the workpiece bending length, greatly reducing the measurement and debugging time, and improving processing accuracy and production efficiency. By setting a rubber pad 319 at the contact position between the table 1 and the bending plate 312, it can play a buffering and shock absorption role when the bending plate 312 is reset, avoiding direct impact between metal parts to generate noise and wear, and also helping to protect the surface of the bending plate 312 and the table 1, extending the service life of the equipment.
