Description

Technical Field

[0001] This utility model belongs to the field of chain processing technology, and in particular relates to a chain bending and turning forming device. Background Technology

[0002] Chain bending technology is commonly used in mining machinery, especially in mining hoists, conveyors, and traction devices. The chain bending process typically refers to the processing of chain links at specific angles or with specific bending shapes during chain manufacturing. This process generally employs specialized equipment to form, bend, or flex the chain to adapt to different operational needs and environments.

[0003] Existing bending devices require workers to use tools to flip the steel after bending one end to form a closed loop, which consumes a lot of manpower and increases the pulling burden. To address this, we propose a chain bending and flipping forming device. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A chain bending and turning forming device includes a bending table. A D-shaped slide rail and a drive mechanism are installed on the side wall of the bending table. Two sliding sleeves are movably fitted on the outer ring of the D-shaped slide rail. A U-shaped frame and a C-shaped sleeve are rotatably installed on both sides of the sliding sleeve. A cylinder is fixedly fitted on the inner ring of one side of the U-shaped frame. A clamping plate is fixedly connected to the output end of the cylinder. The clamping plate is located inside the U-shaped frame. The drive mechanism is connected to the two C-shaped sleeves.

[0006] As a preferred embodiment of the above technical solution, the bending table is fixedly connected to several positioning columns and rotatably connected to a drive shaft. A rocker arm is fixedly sleeved on the outer ring of the drive shaft, and a bending shaft is fixedly connected to the end of the rocker arm away from the drive shaft.

[0007] As a preferred embodiment of the above technical solution, the bending table is equipped with a hydraulic mechanism, which is connected to the drive shaft.

[0008] As a preferred embodiment of the above technical solution, the side wall of the bending table is provided with an opening, the size and shape of which are adapted to the D-shaped slide rail, and the opening is slidably connected with several retaining sleeves, which are slidably connected to the D-shaped slide rail.

[0009] As a preferred embodiment of the above technical solution, the driving mechanism includes a motor fixed to the side wall of the bending table, the output end of the motor is fixedly connected to a rotating shaft, the end of the rotating shaft away from the motor is fixedly connected to a rotating arm, and both C-shaped sleeves are movably fitted onto the outer ring of the rotating arm.

[0010] As a preferred embodiment of the above technical solution, the D-shaped slide rail includes an arc-shaped portion and a straight portion, wherein the dot of the arc-shaped portion, the midpoint of the straight portion, and the center point of the rotating shaft are all located on the same axis.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a cylinder and clamping plate to fix the steel inside the U-shaped frame. Then, the drive mechanism simultaneously drives two sliding sleeves to slide along the D-shaped slide rail. Since the steel is fixed inside the two U-shaped frames, the tilt angle of the two U-shaped frames will remain consistent during the sliding process. When the sliding sleeve rotates half a turn, it can drive the steel to rotate 180°. At the same time, it moves away from the bending station and drives one end of the steel to be completely inside the U-shaped frame, so that it will not touch the bending table when it rotates. This achieves the purpose of automatic bending and rotating, reducing the labor burden of workers. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the chain bending and turning forming device includes a bending table 10. A D-shaped slide rail 20 and a drive mechanism are installed on the side wall of the bending table 10. Two sliding sleeves 21 are movably sleeved on the outer ring of the D-shaped slide rail 20. A U-shaped frame 22 and a C-shaped sleeve 25 are rotatably installed on both sides of the sliding sleeve 21, respectively. A cylinder 23 is fixedly sleeved on the inner ring of one side of the U-shaped frame 22. A clamping plate 24 is fixedly connected to the output end of the cylinder 23. The clamping plate 24 is located inside the U-shaped frame 22. The drive mechanism is connected to the two C-shaped sleeves 25 for transmission.

[0021] Specifically, the steel is fixed inside the U-shaped frame 22 by the cylinder 23 and the clamping plate 24. Then, the drive mechanism simultaneously drives the two sliding sleeves 21 to slide along the trajectory of the D-shaped slide rail 20. Since the steel is fixed inside the two U-shaped frames 22, the tilt angle of the two U-shaped frames 22 will remain consistent during the sliding process. When the sliding sleeve 21 rotates half a turn, it can drive the steel to flip 180°. At the same time, it moves away from the bending station and drives one end of the steel to be completely inside the U-shaped frame 22, so that it will not touch the bending table 10 when flipping. This achieves the purpose of automatic bending and flipping, reducing the labor burden of workers.

[0022] like Figure 1 As shown, the bending table 10 is fixedly connected to several positioning posts 11 and rotatably connected to a drive shaft 12. The outer ring of the drive shaft 12 is fixedly fitted with a rocker arm 13, and the end of the rocker arm 13 away from the drive shaft 12 is fixedly connected to a bending shaft 14.

[0023] Specifically, several positioning posts 11 are arranged in a "V" or "W" shape. After the steel used to produce the chain is placed in them, the drive shaft 12 is rotated, and one end of the steel is bent through the bending shaft 14.

[0024] like Figure 1 As shown, a hydraulic mechanism is installed inside the bending table 10, and the hydraulic mechanism is connected to the drive shaft 12 for transmission.

[0025] Specifically, the hydraulic mechanism includes a hydraulic cylinder fixed inside the bending table 10, one end of the drive shaft 12 passes through the side wall of the bending table 10 and is fixedly connected to a gear, and the output end of the hydraulic cylinder is fixedly connected to a rack, which drives the drive shaft 12 to rotate through the meshing of the rack and the gear.

[0026] like Figure 1 and Figure 2 As shown, the side wall of the bending table 10 has an opening, the size and shape of which are adapted to the D-shaped slide rail 20, and several retaining sleeves are slidably connected to the opening, with the retaining sleeves slidably connected to the D-shaped slide rail 20.

[0027] Specifically, through the sliding engagement of the sleeve and the D-shaped slide rail 20, the D-shaped slide rail 20 is not only fixed at the opening on the side wall of the bending table 10, but also ensures that the sliding of the sleeve 21 on the outer ring of the D-shaped slide rail 20 is unobstructed.

[0028] like Figure 2 and Figure 3 As shown, the drive mechanism includes a motor 26 fixed on the side wall of the bending table 10. The output end of the motor 26 is fixedly connected to a rotating shaft 27. The end of the rotating shaft 27 away from the motor 26 is fixedly connected to a rotating arm 28. Two C-shaped sleeves 25 are movably fitted on the outer ring of the rotating arm 28.

[0029] Specifically, the motor 26 drives the rotating arm 28 to rotate via the rotating shaft 27. The rotation of the rotating arm 28 will drive the two sliding sleeves 21 to slide simultaneously on the D-shaped slide rail 20 via the two C-shaped sleeves 25.

[0030] like Figure 2 and Figure 3 As shown, the D-shaped slide rail 20 includes an arc-shaped part and a straight part. The dot of the arc-shaped part, the midpoint of the straight part, and the center point of the rotating shaft 27 are all located on the same axis.

[0031] Specifically, the initial position of the two sliding sleeves 21 is located at the connection point of the arc-shaped part and the straight part. When one sliding sleeve 21 moves to the arc-shaped part, it will cause the U-shaped frame 22 connected to it to tilt upward. When it moves to the other connection point, it will complete the flipping task.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
