Problems solved by technology

Its shortcomings are: when adjusting different pipe diameters, it is realized by the length of the guide column protruding from the oil cylinder. However, the greater the extension of the guide column, the smaller the strength of the frame and the smaller the force it can withstand. The seaming machine can only seam the steel pipe with thinner wall thickness
In addition, since all the pressing rollers are gathered towards the middle during adjustment, the height of the frame for conveying pipes has to be adjusted accordingly, which brings great trouble to the operation
Moreover, pressing only from three directions with a single structure and a single number of pressing rollers will cause uneven stress on the steel pipes, and the process of pressing may cause deformation of the steel pipes. The pressing effect is not good, and the production capacity of the enterprise is further reduced. efficiency

Abstract

The invention provides a novel steel tube machining device, and particularly relates to an adjustable steel tube joint closing device which comprises a base, a press-fitting roller fixing seat, a first press-fitting roller, a second press-fitting roller, a third press-fitting roller and a lifting support. By means of the adjustable steel tube joint closing device, press-fitting adjustment can be carried out from multiple angles, prominent load bearing capacity and press-fitting precision are achieved, the novel press-fitting rollers can be better attached to the surfaces of tubes to be machined, press-fitting force is accurate and uniform, tube joint closing efficiency and quality can be effectively improved, operation is easy, and operation safety risks are effectively lowered.

Description

technical field [0001] The invention relates to a mechanical device for processing steel pipes, in particular to an adjustable steel pipe jointing device for jointing steel pipes. Background technique [0002] At present, most of the large-diameter steel pipes are made of single steel plates, which need to be fixed by spot welding after forming a cylinder to prepare for the welding process. Before spot welding, since the middle seam is left when the steel pipe is reeled, it is necessary to close the seam of the steel pipe. The existing technical means is to use a joint machine to joint the steel pipes, mostly by stretching out the joint rollers from the press-fit mechanism, and press them from the upper, left and right directions of the steel pipes. When the steel pipe is jointed, it is realized by adjusting the length of the guide column extended by the oil cylinder. Its shortcomings are: when adjusting different pipe diameters, it is realized by the length of the guide c...
