The invention discloses an integrated forming device for additive manufacturing or repairing of an inner circular surface. The integrated forming device comprises a horizontal driving system, a rotarydriving system and a gun body clamping system. The horizontal driving system comprises an eccentric wheel driven by a motor. A circular hole in the eccentric wheel is connected with a connecting rodthrough a hinge joint. The rotary driving system comprises a hollow shaft, a chuck and a tailstock. The chuck driven by a variable speed motor is clamped at one end of the hollow shaft. The other endof the hollow shaft is fixedly connected with the tailstock through a bearing. The other end of the connecting rod is connected with the tailstock through a hinge joint. The gun body clamping system comprises one or more gun body clamps. The gun body clamps are locked on the hollow shaft through lock nuts. The gun body clamps are used for additive manufacturing or repairing of the inner circular surface. According to the integrated forming device for additive manufacturing or repairing of the inner circular surface, the integrated forming effect of preheating, manufacturing (repairing) and post heat treatment can be achieved in one process, the construction efficiency can be significantly improved, and the labor intensity of workers is relieved.
Description
technical field [0001] The invention relates to the technical field of structure repair, in particular to an integrated forming device for additively manufacturing or repairing inner circular surfaces. Background technique [0002] In mining, petroleum and petrochemical, electric power, coal and other industries, the materials or media transported often easily lead to problems such as erosion and wear failure of the structure. To address these problems, on the one hand, it is necessary to consider the influence of the above factors in the structure manufacturing process. Prepare a corrosion-resistant and wear-resistant layer on the surface of the structure; on the other hand, for components that have surface failures, they can continue to be used after surface repair. Using the surface additive method to make the surface functional layer, or using the surface additive manufacturing method to repair the surface of the failed structure, has the advantages of good economy, savi...
