Description

Pipe bending machine's pipe release mechanism

technical field

The utility model relates to a pipe-releasing mechanism of a pipe bending machine, specifically, it is applied to forming circular pipes such as straight pipes into pressure equalizing rings. the

Background technique

In many occasions, it is necessary to use large-diameter pipe circles, such as anti-halo rings on power lines. Traditional anti-halation rings are generally welded by multiple arc circles, which makes the overall dimensional accuracy poor and affects the anti-halation effect. In addition, this anti-halation ring is complicated to manufacture and requires multiple welds. the

For this reason, the patent application number 2009100284318 provides a 360 ° pipe bender, which bends the pipe end when the straight pipe is fed, so that the straight pipe is plastically deformed according to the set center and radius. In order to bend the pipe into a complete 360°, the pinch roller group, guide roller 1, and guide roller 2 are respectively inclined to form a spiral direction, so that the straight pipe also undergoes spiral deformation while undergoing circumferential plastic deformation. After the pipe is broken, press down the pipe head and the fracture to form a full circle, and there is only one weld seam for welding. The accuracy of the tube circle is greatly improved, and the anti-halation effect is enhanced. the

The 360° pipe bending machine provided by the above patent application can only form one round tube at a time. After the round tube is formed, the tube must be broken before the next round tube can be formed. The processing lacks continuity and the production efficiency is low, so it cannot meet the needs of large-scale production. The production demand needs to be further improved. the

Utility model content

The purpose of the present invention is to provide a tube-releasing mechanism for a tube bending machine that further improves production efficiency while ensuring the quality of the round tube. the

For this reason, the technical solution adopted by the utility model is: the utility model includes a shaft, on which a roller that can move up and down along the shaft is sleeved, and the roller is provided with an annular concave surface matched with the tube blank. the

Two sets of pipe releasing mechanisms are arranged, and the pipe blank passes between the two sets of pipe releasing mechanisms. the

The gap between the two groups of tube releasing mechanisms can be adjusted. the

The pipe releasing mechanism of the utility model can continuously feed the pipe blanks, and the moving speed of the rollers on it can be adjusted according to the actual situation, so as to cooperate with the subsequent pipe playing mechanism to bend pipes. The pipe bending efficiency is high and can meet Large-scale production needs. the

Detailed ways

Below it is placed in the whole system and the utility model is further described, to better understand the purpose of the invention of the utility model. the

The utility model comprises a frame, a pipe delivery mechanism and a pipe bending mechanism 6 arranged on the frame; wherein the pipe delivery mechanism 6 includes a conveying mechanism 1 and a pipe releasing mechanism arranged between the conveying mechanism 1 and the pipe bending mechanism 6 , the pipe release mechanism includes a shaft 4 vertically arranged on the frame, the shaft 4 is sleeved with a roller 3 that can move up and down along the shaft 4, and the roller 3 is provided with an annular concave surface that matches the tube blank 2; The tube mechanism 6 includes a rotating cylinder, the outer circumference of which is processed into a spiral groove corresponding to the tube blank 2, the lower end of the tube bending mechanism 6 is provided with a clamp 5 for fixing the end of the tube blank 2; The speed of the upward movement corresponds to the rotational speed of the cylinder. the

The pipe releasing mechanism described in the utility model is provided with two groups, and the pipe blank 2 is passed between the two groups of pipe releasing mechanisms. the

The gap between the two groups of pipe releasing mechanisms described in the utility model is regulated by the adjusting mechanism 7 . the

The pipe releasing mechanism described in the utility model is inclined at an angle, and its inclination angle corresponds to the angle of the corresponding spiral groove. the

The product of the present utility model can be carried out according to the following steps:

1) Turn on each driving mechanism, the tube blank 2 passes through the conveying mechanism 1 to the tube release mechanism, the tube blank 2 is positioned by the annular concave surface of the tube release mechanism and transported to the spiral groove, and the end of the tube blank 2 passes through the pipe bending mechanism 6 Fixture 5 of the lower part is fixed;

2) After setting the rotation speed of the pipe bending mechanism 6 and the corresponding moving speed of the roller 3 on the shaft 4, the tube blank 2 is spirally formed into a round pipe 8 on the pipe bending mechanism 6 along the spiral groove;

3) After the spiral forming, the clamp 5 is disassembled, and the round tube 8 is single-out outward under the action of its own metal elastic force, and is separated from the bending mechanism 6, and taken out;

4) Carry out follow-up processing such as cutting and grinding on the taken out circular tube 8 according to the situation to form the desired product. the
