One-step method hot-bending bend device and process

Abstract

The invention discloses a one-step method hot-bending bend device and process. The process comprises the steps that firstly, the theoretical length of a formed bend is calculated based on the compensation principle, feeding is carried out through an automatic plasma fire cutting machine or a sawing machine, a mechanical bevelling machine is used for beveling, and a short joint, the raw material of the bend, is manufactured; secondly, the circle center of a fast-mounting fixture and the center of a three-claw locating chuck are adjusted to be on the same line, feeding is carried out, a three-claw locating top is sleeved with one end of a steel pipe raw material in a sliding mode, a bore spine wheel is used for locking, the other end of the steel pipe raw material is placed in the fast-mounting fixture, an auxiliary push-pull oil cylinder is used for clamping, and then a fast-mounting claw bolt is used for locking; thirdly, a medium frequency heating device is used for heating, a hydraulic pulling device is used for pulling, meanwhile, a rocker arm is rotated to the specified angle, and bend heating and bending are completed; fourthly, the bend is offline and put into a storehouse after passing inspection. Key portions of an original process device are innovated, the original process device and procedures are changed, and therefore the aims of improving production efficiency and guaranteeing product quality are achieved.

Description

technical field [0001] The invention relates to a manufacturing process and a device for hot-simmering pipe bending, in particular to a one-step hot-simmering pipe bending device and process. Background technique [0002] In recent years, with the rapid development of long-distance pipeline construction, the importance of hot-simmered pipe bends in pipeline construction has increased, and more and more people have used them. Bending pipes have become one of the key accessories for long-distance pipeline construction. Its production speed and quality seriously restrict the construction period of long-distance pipelines. At present, the manufacturing process of the commonly used hot-simmering pipe bending process device is: feeding, setting off, simmering, cutting, off-line, breaching, shaping, and forming. There are many follow-up processing procedures after the bent pipe is simmered in this process, which seriously affects the production efficiency and quality of the bent...

Problems solved by technology

This process has many follow-up processing procedures after the bent pipe is simmered, which seriously affects the production efficiency and quality of the bent pipe

[0003] The original process device has the following disadvantages: 1. Release the wire after feeding, which increases the production preparation time; 2. After simmering, it needs to be cut before it can be offline, which increases the post-processing time; The breach bracket and larger processing space increase the difficulty of the breach and the efficiency of the breach is not high; 4. It takes more time for plastic surgery, which affects the delivery time

In short, there are disadvantages such as slow production efficiency, need for shaping, many unsafe factors, and large working space in the production of hot-simmered pipes with the original process equipment and process flow, which cannot meet the urgent needs of the current long-distance pipeline project construction. sex
