Description

Technical Field

[0001] This utility model relates to the technical field of connecting ring production equipment, and in particular to a bending device for connecting ring production. Background Technology

[0002] Shackles, also known as connecting rings, are commonly used connecting devices in mechanical engineering. Common engineering shackles include European-style large bow shackles, European-style large DEE shackles, round-head shackles, square-head shackles, and D-shaped shackles, among others. In rescue operations, shackles are typically called connecting rings and are essential connecting devices between wire ropes, between wire ropes and the vehicle body, between wire ropes and pulleys, and between rigid traction frames and the vehicle body. Depending on their application, connecting rings come in different forms; commonly used ones include D-shaped connecting rings, double D-shaped connecting rings, and connecting sleeves.

[0003] For example, CN216027324U discloses a bending device for producing connecting rings, including a workbench, a placement table, and a top plate. Extrusion blocks are located on both opposite sides of the placement table at the top of the workbench. A synchronous moving mechanism is located inside the workbench below the two extrusion blocks. A fixing ring is located directly above the placement table. A lifting mechanism is located on the top of the top of the workbench on the other side of the placement table. A mounting base is connected to the top center of the mounting base. A fixing plate is welded to the top center of the mounting base. A drive shaft, a first driven shaft, and a second driven shaft are sequentially and longitudinally rotatably connected to the fixing plate. A driving mechanism is located on the top of the mounting base. Bending rings are welded to the top ends of both the drive shaft and the second driven shaft. This utility model provides a stable and secure fixing of the connecting ring material, and the fixing process is simple. It allows for simultaneous bending of both ends of the connecting ring material, resulting in higher automation, improved work efficiency, and better bending effect of the connecting ring.

[0004] However, in the current technology, the traditional bending device is difficult to meet the needs of mass production and high-speed production due to the long cycle time of single-station bending in actual application, which leads to a certain degree of limitation on the bending efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to solve the problems of limited bending efficiency in the existing technology, which involves single-station bending, long cycle time, difficulty in meeting the needs of mass production and high-speed production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bending device for producing connecting rings, comprising a main body, a positioning mechanism provided on one side of the upper surface of the main body, the positioning mechanism including a first mounting groove formed on one side of the upper surface of the main body, a first bidirectional lead screw being driven in the inner cavity of the first mounting groove, a first motor being fixedly mounted on the outer wall of the main body, and the output end of the first motor being drivenly connected to one end of the outer side of the first bidirectional lead screw, a first moving block being symmetrically driven on the surface of the first bidirectional lead screw, a limiting component being provided on the outer wall of the first moving block, the limiting component including a frame, the frame being fixedly mounted on the outer wall of the first moving block, a connecting frame being symmetrically fixed on the outer wall of the frame, a guide rod being symmetrically slidably mounted in the inner cavity of the connecting frame, a push-pull plate being fixedly mounted on the outer end of the guide rod, a limiting plate being fixedly mounted on the inner end of the guide rod, and a return spring being elastically provided between the outer wall of the frame and the inner wall of the connecting frame, a screw being driven at the center of the upper surface of the connecting frame, and a pressure plate being driven at the end of the screw.

[0007] In a preferred embodiment, a second mounting groove is provided on the upper surface of the first movable block, a second bidirectional lead screw is driven in the inner cavity of the second mounting groove, a second motor is fixedly provided on the outer wall of the first movable block, and the output end of the second motor is drivenly connected to one end of the second bidirectional lead screw.

[0008] In a preferred embodiment, a limiting groove is formed on the outer side wall of the first moving block, and a second moving block is symmetrically driven on the surface of the second bidirectional lead screw, and the second moving block is slidably connected to the limiting groove.

[0009] In a preferred embodiment, a positioning rod is rotatably provided on the upper surface of the second moving block.

[0010] In a preferred embodiment, a fixing block is fixedly provided on the other side of the upper surface of the main body, and a hydraulic push rod is fixedly provided on the inner side wall of the fixing block.

[0011] In a preferred embodiment, the output end of the hydraulic push rod is provided with a mounting plate, and bending components are symmetrically and movably arranged on both sides of the surface of the mounting plate.

[0012] In a preferred embodiment, the end of the bending component is threaded with a locking bolt.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention uses a limiting component to pull a push-pull plate outward. The push-pull plate, through a guide rod, moves the limiting plate outward and simultaneously compresses a return spring. Then, the stacked connecting rings are placed in the inner cavity of the frame. The push-pull plate is released, and as the return spring rebounds, it causes the limiting plate to limit and fix the stacked connecting rings of the same size. Then, by turning the screw, the pressure plate moves downward, and the pressure plate limits the connecting ring at the top of the stack, facilitating subsequent processing. This allows multiple connecting rings to be bent at once, improving the practicality and bending efficiency of the device.

[0015] This utility model, by setting up a positioning mechanism, starts a first motor to drive a first bidirectional lead screw to rotate. The first bidirectional lead screw drives a first moving block and a frame to slide towards each other along a first mounting groove. At the same time, a second motor is started, and the output end of the second motor drives a second bidirectional lead screw to rotate. The second bidirectional lead screw drives a second moving block and a positioning rod to move towards each other. With the cooperation of the limiting groove, connecting rings of different sizes and lengths are fixed, further improving the practicality and processing efficiency of the device.

A limiting plate 16 is fixedly installed at the inner end of the frame 12, and a return spring 17 is elastically installed between the outer side wall of the frame 12 and the inner side wall of the connecting frame 13. A screw 18 is driven at the center of the upper surface of the connecting frame 13, and a pressure plate 19 is driven at the end of the screw 18. Pulling the push-pull plate 15 outward causes the limiting plate 16 to move outward through the guide rod 14, and at the same time compresses the return spring 17. Then, the stacked connecting rings are placed in the inner cavity of the frame 12. The push-pull plate 15 is released, and as the return spring 17 rebounds and resets, it drives the limiting plate 16 to limit and fix the stacked connecting rings of the same size. Then, by turning the screw 18, the pressure plate 19 is moved down, and the pressure plate 19 limits the connecting ring at the top of the stack, which facilitates subsequent processing. This allows multiple connecting rings to be bent at one time, improving the practicality and processing efficiency of the device.

[0024] like Figure 1-4As shown, a second mounting groove 6 is provided on the upper surface of the first moving block 5. A second bidirectional lead screw 7 is driven in the inner cavity of the second mounting groove 6. A second motor 8 is fixedly installed on the outer wall of the first moving block 5, and the output end of the second motor 8 is drivenly connected to one end of the second bidirectional lead screw 7. A limit groove 11 is provided on the outer wall of the first moving block 5. A second moving block 9 is symmetrically driven on the surface of the second bidirectional lead screw 7, and the second moving block 9 is slidably connected to the limit groove 11. A positioning rod 10 is rotatably installed on the upper surface of the second moving block 9. When the first motor 4 is started, it drives the first bidirectional lead screw 3 to rotate. The first bidirectional lead screw 3 drives the first moving block 5 and the frame 12 to slide towards each other along the first mounting groove 2. At the same time, the second motor 8 is started. The output end of the second motor 8 drives the second bidirectional lead screw 7 to rotate. The second bidirectional lead screw 7 drives the second moving block 9 and the positioning rod 10 to move towards each other. With the cooperation of the limit groove 11, connecting rings of different sizes and lengths are fixed, which further improves the practicality and processing efficiency of the device.

[0025] like Figure 1-4 As shown, a fixing block 20 is fixedly installed on the other side of the upper surface of the main body 1. A hydraulic push rod 21 is fixedly installed on the inner wall of the fixing block 20. A mounting plate 22 is driven to the output end of the hydraulic push rod 21. Bending components 24 are symmetrically and movably arranged on both sides of the surface of the mounting plate 22. A locking bolt 23 is threaded at the end of the bending component 24. The output end of the hydraulic push rod 21 drives the locking bolt 23 to move forward through the mounting plate 22, bending the connecting ring. The mounting plate 22 and the locking bolt 23 are connected by the threaded installation of the bending component 24, which makes it easy to replace different locking bolts 23 according to actual needs, making disassembly and assembly more convenient and easy to use.

[0026] Working principle: In use, firstly, the push-pull plate 15 is pulled outward. The push-pull plate 15 drives the limiting plate 16 to move outward through the guide rod 14, and at the same time compresses the return spring 17. Then, the stacked connecting rings are placed in the inner cavity of the frame 12. The push-pull plate 15 is released. As the return spring 17 returns to its original position, it drives the limiting plate 16 to limit and fix the stacked connecting rings of the same size. Then, by turning the screw 18, the pressure plate 19 is moved down. The pressure plate 19 limits the connecting ring at the top of the stack, which facilitates subsequent processing. This allows multiple connecting rings to be bent at once. The first motor 4 is started to drive the first bidirectional lead screw 3 to rotate. The first bidirectional lead screw 3 drives the first moving block. 5. The frame 12 slides along the first mounting groove 2 towards each other, and at the same time the second motor 8 is started. The output end of the second motor 8 drives the second bidirectional lead screw 7 to rotate. The second bidirectional lead screw 7 drives the second moving block 9 and the positioning rod 10 to move towards each other. With the cooperation of the limiting groove 11, the connecting rings of different sizes and lengths are fixed. Then the hydraulic push rod 21 is started. The output end of the hydraulic push rod 21 drives the locking bolt 23 to move forward through the mounting plate 22, which bends the connecting ring. The mounting plate 22 and the locking bolt 23 are connected by a bending component 24 threaded installation, which makes it easy to replace different locking bolts 23 according to actual needs. The disassembly and assembly are more convenient and easy to use, and it is suitable for large-scale promotion.
