Assembly welding process method of elastic oil tanks with communication pipe structure

Abstract

The invention relates to an assembly welding process method of elastic oil tanks with a communication pipe structure. After being assembled, an elastic oil tank chassis is leveled and fixed to a positioner (turnover frame) platform, and L-shaped tie bars and wedge-shaped plates are adopted for pre-tightening force application and deformation resisting. Supporting tie bars are assembled and welded between the adjacent elastic oil tanks. The welding position of the elastic oil tank chassis is adjusted through the positioner (turnover frame) platform, full-position welding is carried out, welding seam inspection is carried out after welding is finished, and tie bar removing, rigid fixing, size measuring and cleaning are carried out. By means of the combination of rigid fixing, deformation resisting and pre-tightening force application, the key process problem of size control over the communication pipe type elastic oil tank chassis is solved. The method has the beneficial effects that manufacturing cost is low, the process is reasonable and simple, and the product size performance and product cost performance can be improved.

Description

technical field [0001] The invention relates to an assembly and welding process method of an elastic oil tank with a connecting pipe structure. Background technique [0002] In the past, the assembly and welding process of the elastic oil tank of the hydro-generator is to weld the elastic oil tank in a free state after it is assembled on the chassis. Due to the welding shrinkage stress of the connecting pipe, although the elastic oil tank assembled and welded by this method is simple in process and short in production cycle, when the size of the elastic oil tank is measured after welding, the flatness of the chassis may be poor, which will affect the The verticality of the elastic oil tank is greatly affected by the unevenness of the chassis as the thickness of the chassis becomes thinner and the diameter becomes larger. Contents of the invention [0003] The object of the present invention is to provide an assembly and welding method of an elastic oil tank with a connect...
