Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is: when making an elbow, because the inner diameter of the corner is deformed, and the pipe wall at the corner bears a large internal stress due to tension and pressure, often after the bending is stretched, the bend of the elbow Deviations in camber resulting in too large a tolerance to fit into existing pipeline fittings, making it difficult to fit into existing pipelines

[0027] refer to figure 1 , which is the first embodiment of the present invention, this embodiment provides an elbow processing device, a clamping assembly 100 and an adjusting assembly 200, the clamping assembly 100 includes a base 101, a first telescopic rod 102 and a splint 103, the base 101 The first telescopic rod 102 is arranged symmetrically on the top, and the first telescopic rod 102 is connected to the splint 103; the two ends of the base 101 protrude upwards, and the first telescopic rod 102 is fixedly connected to the opposite sides of the two ends of the base 101, and the first telescopic rod 102 is opposite The splints 103 are respectively fixedly connected near the ends, and the inner wall of the splints 103 is arc-shaped, which is convenient for clamping and fixing the ends of the bent pipes.

[0028] The adjustment assembly 200 includes a fixed seat 201, a rotating shaft 202, a gear 203, a tooth plate 204 and a second telescopic rod 205. The clamping assembly ...

Embodiment 2

[0030] refer to Figure 1~6 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A cavity 101a is provided inside the base 101. The cavity 101a is arranged inside the base 101 corresponding to the shape of the base 101. The cavity 101a passes through the first through hole 101b communicates with the outside world, the gas can enter the cavity 101a through the first through hole 101b, and the cavity 101a communicates with the inside of the first telescopic rod 102, the gas in the cavity 101a can enter the inside of the first telescopic rod 102, through the air pressure The change controls the expansion and contraction of the first telescopic rod 102 .

[0031] The fixed seat 201 is provided with a groove 201a, and the rotating shaft 202 is arranged to rotate in the groove 201a, and the inner wall of one side of the groove 201a is provided with a chute 201b, and the tooth plate 204 is provided with a slider 204a on the s...

Embodiment 3

[0039] refer to Figure 1 ~ Figure 3 , Figure 5 and Image 6 , is the third embodiment of the present invention. This embodiment is based on the above two embodiments. During use, the compressed gas is passed into the intake pipe 301a through the existing air pump, and the gas in the intake pipe 301a enters the control pipe 301, and the gas Pass through the vent hole 301c-5 on the second column 301c-3 and enter between the first column 301c-1 and the second column 301c-3, enter the tee head 302 through the second through hole 301d, and then pass through the connecting pipe 302a enter the sleeve 202b, and enter the first through hole 101b through the rotating shaft 202, enter the cavity 101a, and then enter the first telescopic rod 102. When the gas continues to pass through, the air pressure increases, which can push the first telescopic rod 102 to extend. Drive the splint 103 to clamp one end of the elbow; the gas in the tee 302 enters the first through hole 101b on the ot...

Abstract

The elbow machining device comprises a clamping assembly and an adjusting assembly, the clamping assembly comprises a base, first telescopic rods and a clamping plate, the first telescopic rods are symmetrically arranged on the base, and the first telescopic rods are connected with the clamping plate; the adjusting assembly comprises a fixing base, a rotating shaft, a gear, a toothed plate and a second telescopic rod, the number of the clamping assemblies is two, one clamping assembly is fixedly arranged on the fixing base, and the bottom of the other clamping assembly is connected with the rotating shaft; by continuously introducing gas into the driving assembly, the driving assembly can drive the adjusting assembly to rotate and drive the clamping assembly fixed on the rotating shaft to rotate while the clamping assembly can clamp the elbow and continuously introducing gas, and by matching with the clamping assembly fixed on the fixed seat, the bending degree of the elbow can be adjusted; the matching tolerance between the elbow and the pipeline joint is reduced, and the elbow is convenient to install.

Description

technical field [0001] The invention relates to the technical field of metal pipe elbow processing, in particular to an elbow processing device. Background technique [0002] Metal pipes are widely used in daily necessities and various equipment, and are widely used to transport fluid media. The elbow is one of the main parts connecting the cement truck and the wellhead. In field operations, due to environmental constraints, it is inevitable to use metal elbows for pipeline connections to change the flow direction of fluids. [0003] At present, the swivel elbow manufacturing process adopts the simmer bending process, which is to make the elbow by stretching the straight-through pipe. Due to the deformation of the inner diameter at the corner of the elbow, and the pipe wall at the corner is subject to a large internal pressure due to tension and pressure. Stress, after stretching and bending, there is a deviation in the curvature of the elbow, and there is often a phenomeno...
