Abstract

The utility model relates to a steel pipe welder with porous flame. The steel pipe welder with porous flame is characterized in that the inner side of a heater is provided with a plurality of flame jets, and the heater can move along a steel pipe in an axial direction and swing along the steel pipe in a circumferential direction; a left bracket and a right bracket are respectively provided with rolling dragging mechanisms; the input quantity of oxygen and acetylene gas are both controlled by a control cabinet. Compared with the prior art, the utility model has the advantages of fast welding speed, high quality, low cost, low labour intensity, low welding inner stress, etc.

Description

Porous flame pipe-welding machine

The utility model relates to a kind of bonding machine, exactly is a kind of porous flame pipe-welding machine that is exclusively used in welded still pipe.

At present, use steel pipe to be applied to various fields more and more at large as conveyance conduit, as: petroleum transportation pipeline, various water conveyance conduit, all gases conveyance conduit etc.But steel pipe then often still adopts old-fashioned manual welding mode with the Welding Problems of docking between the steel pipe, i.e. manual arc welding.This welding manner has following shortcoming: 1, because the place is narrow, old friend worker welds inconvenience.2, labour intensity is big, and speed is slow; 3, welding quality is low, the cost height.

The purpose of this utility model is according to the shortcoming that exists in the problems referred to above, for the user provides a kind of porous flame pipe-welding machine novel, that be exclusively used in welded still pipe.

This reality is novel to be to tow mechanism (1) by rolling, left socle (3), heater (4), right support (5), oil motor (6), switch board compositions such as (17), treating the longitudinal thrust of welding steel pipe is finished by hydraulic thrust mechanism, heater is made up of two and half garden shape heaters, its technical essential is: have several flame jets on the inboard of heater, and this heater not only can move axially but also can circumferentially swing simultaneously, and then the even heating of welding steel pipe is treated in realization, a left side, a rolling respectively is installed on the right support tows mechanism (1), so that realize after the welding easily with a left side, right support is removed; A left side, right support is tightly held locking oil cylinder (2) under the arm by two pipe fittings to holding under the arm of steel pipe and is finished; Oxygen input quantity, the acetylene gas input quantity of whole bonding machine are all controlled by switch board 17.

After the utility model is realized, can weld steel pipe easily, both need not any welding rod, welding agent, the quality of welding is high again.This machine compared with the prior art has advantages such as speed of welding is fast, quality is high, and labour intensity is low, and welding interior stress is little.
