Abstract

The utility model discloses a kind of PE winding pipe weldering enlarging fixture, it is divided into support system and enlarging binding two parts, support system mainly contains screw mandrel, hinge, bearing, gripper shoe and nut composition, enlarging fastening system is screw mandrel, circular hard plate and nut composition mainly, and two systems form fixture jointly.When winding pipe body and winding pipe enlarging are clamped by fixture, make not easily to produce displacement between winding pipe body and winding pipe enlarging, when welding, also rolling can be carried out by side weld edge fit, do not worry in the process of rolling, weld being come off, greatly increase work efficiency, reduce technical requirement simultaneously, welding of many specifications winding pipe body and enlarging can also be met simultaneously.

Description

A PE winding pipe welding expansion fixture

technical field

The utility model relates to a fixture, in particular to a PE winding pipe welding flaring fixture.

Background technique

At present, there is no special product on the market for welding fixtures for pipe flaring. The company developed this product according to its own needs. During traditional welding, on the welding platform, multiple people are required to lift the pipe flaring and hold it close. Winding the welding end of the pipe, at the same time, the welding personnel need to weld around the pipe instead of rotating the pipe, so welding is extremely inconvenient and requires multiple people to participate. For some heavy pipes, the operation is more troublesome. It greatly affects the welding efficiency and increases the labor cost.

Contents of the invention

The purpose of the utility model is to provide a convenient pipe flaring welding jig, so that the winding pipe body and the winding pipe flaring welding place are in close contact, and at the same time, displacement is not easy to occur, and the operation is convenient.

A PE winding pipe welding flare fixture, the fixture is divided into a pipe body support system and a flare fastening plate; the pipe body support system consists of three sets of hinges, three supports, screw rods, four support plates and Composed of nuts, wherein the support is fixed on the screw, and the support is sleeved on the screw, and all hinges and supports, as well as hinges and support plates are all in loose connection; the flared fastening plate is a circular There is a round hole in the center of the hard plate, through which the round hard plate can pass through the screw rod, and the diameter of the flared fastening plate is between the diameters of the two ends of the flared hole.

The size of the longitudinal diameter of the support system can be adjusted by adjusting the nut on the screw rod.

The flared fastening plate is a circular hard plate (12), with a round hole passing through the screw rod in the center, and the diameter of the flared fastening plate is between the diameters of the two ends of the flared hole.

The beneficial effects of the utility model are as follows: when the clamp clamps the winding pipe body and the winding pipe flare, the winding pipe body and the winding pipe flare are kept concentric and are not easily displaced. During welding, it is also possible Rolling while welding, there is no need to worry about the welding place falling off during the rolling process, which greatly improves work efficiency and reduces technical requirements. At the same time, it can also meet the welding of multi-specification winding pipe body and winding pipe flare.

1 screw rod; 2 nut; 3 first hinge; 4 second hinge; 5 third hinge; 6 support plate; 7 first support; 8 second support; 9 third support; 10 winding pipe body; 11 winding tube flaring; 12 circular hard plate; 13 nut.

Detailed ways

Embodiments of the present utility model are as follows:

When welding, first unscrew the nut 13 of the fixture, take off the circular hard plate 12, and then loosen the nut 2, so that the longitudinal diameter of the fixture support system is reduced to a winding tube that can meet the corresponding specifications, and the support system Stretch into the welding end of the winding pipe body 10, then slowly tighten the nut 2 with a wrench, and adjust the length of the support system while tightening to ensure that when the nut 2 is tightened, the four support plates 6 of the support system and the winding pipe body No displacement can occur between 10, and the nut 2 is outside the welded end of the pipe body, then pass the corresponding winding pipe flare 11 through the screw mandrel 1, move it close to the welding end of the winding pipe body 10, and then Put the round hard plate 12 of the corresponding diameter on the screw rod 1, put the nut 13 on the screw rod, and tighten it with a wrench until the tight contact between the winding tube body 10 and the winding tube flare 11 does not occur. Displacement, and then welding.

After welding, unscrew the nut 13, remove the round hard plate 12, and then use a wrench to screw the nut 2 outward. At this time, the three sets of hinges will shrink as the nut 2 moves outward. When the shrinkage reaches a certain level, Take out the fixture support system, and the whole set of welding process is completed at this time. the

The above is only an embodiment of the utility model, and does not limit the scope of patent protection of the utility model. Any equivalent structure or equivalent transformation made by using the specification of the utility model and the contents of the accompanying drawings, or directly or indirectly using Other relevant fields other than the utility model can be regarded as within the patent protection scope of the utility model.
