Special equipment for large cylinder butt milling and welding

Abstract

The invention relates to special equipment for large cylinder butt milling and welding, belonging to the field of cylinder butt tools and equipment. The special equipment comprises no fewer than two cylinder rolling frames, wherein a guide rail is arranged under the cylinder rolling frames, and a pair of 360-degree-rotation edge milling machines is arranged at the left end of the guide rail; the left-end 360-degree-rotation edge milling machine is fixed at the left end of the guide rail, and the right-end 360-degree-rotation edge milling machine is arranged on the guide rail; a V-shaped support is arranged between the two 360-degree-rotation edge milling machines, and a ratchet gear is arranged on the V-shaped support; a welding device is fixedly arranged on one side of the right end of the guide rail, and a roller, a roller driving motor for driving the roller to rotate and a driving motor I for driving each cylinder rolling frame to move on the guide rail are arranged on each cylinder rolling frame. The cross section of a cylinder is milled before butting, so that the cross section of the cylinder is even enough, the butting positions of the cylinder is accurate, weld joints are formed in one step, formation is beautiful, and the percent of pass of one-step forming is high. Meanwhile, secondary welding in a tank body of operators is avoided, and the harm of dust and high temperature to a human body in the inner welding process is reduced.

Description

technical field

[0001] The invention belongs to the field of tooling equipment for butt jointing of cylinders, in particular to a special equipment for butt milling and welding of large cylinders. Background technique

[0002] At present, the methods of edge milling, butt jointing and welding of large cylinders are mainly divided into the following steps: the first step is to grind the edges of the cylinders to be joined with a grinding wheel grinder, which is low in efficiency and labor-intensive High, and the size of the grinding is not uniform, resulting in uneven cross-section of the tank body, resulting in uneven butt joint gaps, which increases the difficulty for subsequent butt joints and welding; the second step is to hang one of the tanks to the other tank with a crane The body is close, and it is placed in a suitable position according to the observation of the operator under manual adjustment. This method only has axial butt joint without circumferential adjustmen...
