Longitudinal seam back gouging equipment for composite plate pressure vessel

Abstract

The invention discloses longitudinal seam back gouging equipment for a composite plate pressure vessel. The longitudinal seam back gouging equipment comprises a first base and a second base. Four groups of rotating supporting structures are evenly arranged on the first base from front to back in sequence, the rotating supporting structures include fixed frames, driving rollers and driven rollers,the right ends of the fixed frames are connected with pressing structures, the pressing structures include stand columns, rocker arms and pressing wheels, a sliding seat is arranged on the second base, a second rack structure for driving the sliding seat to slide forward and backward is arranged between the second base and the sliding seat, a gear box is rotatably connected to the upper part of the sliding seat, and a milling cutter is installed on a main shaft of the right end of the gear box. The longitudinal seam back gouging equipment has the beneficial effects that manual operation is replaced, the labor intensity of manual operation is reduced, the processing cost is reduced, the workshop environment is improved, the process quality is improved, the engineering progress is shortened,uncontrollable factors of manual polishing are improved, the welding quality is improved, and the appearance quality of products is improved.

Description

technical field [0001] The invention relates to the technical field of root cleaning of weld seams, in particular to a root cleaning device for longitudinal seams of composite plate pressure vessels. Background technique [0002] Modern industrial technology is changing with each passing day, especially the requirements for the application of metal materials are becoming more and more stringent, coupled with the continuous progress of metallurgical technology, and the demand for new material applications in modern industrial technology, composite panels have emerged as the times require. The application of composite plates greatly reduces the production cost of pressure vessel pipes and chemical equipment industries. Since composite plates are the butt joints of two different metal materials with completely different functions, the welding techniques to be dealt with are also different, and the requirements for welding are also different. more stringent. In the current indu...

Problems solved by technology

However, since a certain amount of slag will be generated during the welding process of the internal bead, it must be cleaned before welding the outside of the bead to avoid welding defects caused by contamination of the outside of the bead.

In order to deal with the cleaning of the outside of the weld bead, the external slag is usually processed by manual grinding with an angle grinder, but this cleaning method is not only time-consuming and laborious, but also causes a certain degree of pollution to the working environment of the workshop

At the same time, the strength of manual grinding is difficult to grasp in place, and the weld bead is also deep and shallow, which may easily cause the original welded bead to be thinned or worn through. If the weld bead is externally welded without treatment, it will often damage Welding inside the bead causes damage, resulting in contamination of the inside of the bead, resulting in weld defects
