Description

Technical Field

[0001] The utility model relates to the technical field of fully welded ball valves, in particular to a fully welded ball valve pipe bending device. Background Art

[0002] The valve seat of the fully welded ball valve is composed of a carbonized Teflon sealing ring and a disc spring, which makes it highly adaptable to changes in pressure and temperature, and will not produce any leakage within the marked pressure and temperature range. When manufacturing some models of fully welded ball valves, it is necessary to bend the original component of the ball valve, that is, the steel pipe. The current device for bending the steel pipe requires manual operation of the instrument to flush the bent pipe out of the device after the pipe bending operation is completed, resulting in a low degree of automation.

[0003] The currently published patent: CN218283314U, discloses a fully welded ball valve pipe bending device. The operation of the hydraulic cylinder drives the transmission rod to operate, causing the pressure plate and forming block to sink, and the pipe of the fully welded ball valve set on the mold to bend. After that, the electric telescopic rod is extended and the movable splint can be used to automatically punch the pipe out of the device, realizing automatic welding and output of the pipe, and improving the degree of automation of such devices in the existing technology.

[0004] Based on the above search, it was found that the above patent has the following problems when used: when the pipe bending device is in use, the electric telescopic rod is extended and the movable splint is used to automatically punch the pipe out of the device, realizing automatic welding and output of the pipe, and improving the degree of automation of such devices in the prior art. Since there is an extrusion effect between the steel pipe and the forming die during the pressing process, the steel pipe is easily stuck on the surface of the forming die. The steel pipe cannot be smoothly removed by simply adjusting the inclination angle of the splint. At this time, the staff is required to manually remove the steel pipe, which reduces the practicality of the pipe bending device. Utility Model Content

[0024] See also Figure 1-4The utility model provides a technical solution: a fully welded ball valve pipe bending device, including a pipe bending frame 1 and a pipe disassembly device, the top of the pipe bending frame 1 is fixedly connected to a mounting frame 2, the inside of the mounting frame 2 is slidably connected to a slide plate 3, the bottom of the slide plate 3 is fixedly connected to a punch pressing block 4, the top of the mounting frame 2 is fixedly installed with a hydraulic lifter 5, the output end of the hydraulic lifter 5 is fixedly connected to the top of the slide plate 3, the top of the pipe bending frame 1 is fixedly installed with a cylinder 6, the top of the pipe bending frame 1 is slidably connected to a die 7, the output shaft of the cylinder 6 is fixedly connected to the surface of the die 7, the top of the die 7 is placed with a pipe 8, and the front side of the pipe bending frame 1 is fixedly connected to a triangular slide 9.

[0025] After the staff puts the pipe 8 on the top of the die 7, the hydraulic lift 5 is started. The output end of the hydraulic lift 5 moves downward and drives the slide 3 to move downward inside the mounting frame 2. The downward movement of the slide 3 drives the punch block 4 to move downward to extrude the surface of the pipe 8. Then, the pipe 8 is bent at the top of the die 7 through the extrusion action of the punch block 4, completing the pipe bending process of the pipe 8.

[0026] The pipe disassembly device includes two support blocks 10, a rotating shaft 11, two disassembly wheels 12, a first sprocket 13, a chain 14, a servo motor 15 and a second sprocket 16. The two support blocks 10 are fixedly connected to the top of the pipe bending frame 1, the rotating shaft 11 is rotatably sleeved inside the two support blocks 10, the two disassembly wheels 12 are fixedly sleeved on the surface of the rotating shaft 11, the first sprocket 13 is fixedly sleeved on the right end of the rotating shaft 11, the chain 14 is meshed and connected to the surface of the first sprocket 13, the servo motor 15 is fixedly installed on the bottom wall of the pipe bending frame 1, the second sprocket 16 is fixedly installed at the output end of the servo motor 15, and the second sprocket 16 is meshed and connected with the chain 14.

[0027] When the pipe 8 is bent, the staff starts the cylinder 6 again. The output shaft of the cylinder 6 moves forward and drives the die 7 and the pipe 8 to move forward. When the pipe 8 moves to the position of the two disassembly wheels 12, the servo motor 15 starts and drives the second sprocket 16 to rotate. The rotation of the second sprocket 16 can drive the first sprocket 13 to rotate through the chain 14. The rotation of the first sprocket 13 drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 can drive the two disassembly wheels 12 to rotate at the same time. At this time, the rotation of the two disassembly wheels 12 can drive the pipe 8 to move upward and break away from the surface of the die 7 through the arc-shaped blades on the surface, and make the pipe 8 fall on the surface of the triangular slide 9. The triangular slide 9 automatically slides downward to complete the disassembly process of the pipe 8. The pipe 8 is disassembled by the two disassembly wheels 12, which can prevent the pipe 8 from being stuck on the surface of the die 7, thereby ensuring that the pipe 8 is smoothly removed. At this time, the staff no longer needs to manually remove the pipe 8, which not only reduces the labor intensity of the staff, but also improves the practicality of the pipe bending device.

[0028] Working principle: For this fully welded ball valve bending device, after the worker puts the pipe 8 on the top of the die 7, he starts the hydraulic lift 5. The output end of the hydraulic lift 5 moves downward and drives the slide 3 to move downward inside the mounting frame 2. The downward movement of the slide 3 drives the punch block 4 to move downward to squeeze the surface of the pipe 8. Then, the pipe 8 is bent at the top of the die 7 by the squeezing action of the punch block 4. The worker then starts the cylinder 6. The output shaft of the cylinder 6 moves forward and drives the die 7 and the pipe 8 to move forward. When the pipe 8 moves to the two disassembly positions, the two disassembly positions are opened. When the unloading wheel 12 is in the position, the servo motor 15 starts and drives the second sprocket 16 to rotate. The rotation of the second sprocket 16 can drive the first sprocket 13 to rotate through the chain 14. The first sprocket 13 rotates and drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 can drive the two disassembly wheels 12 to rotate at the same time. At this time, the rotation of the two disassembly wheels 12 can drive the pipe 8 to move upward and detach from the surface of the die 7 through the arc-shaped blades on the surface, and make the pipe 8 fall on the surface of the triangular slide 9. The triangular slide 9 automatically slides downward to complete the disassembly process of the pipe 8.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
