Technical Field

[0001] The utility model belongs to the technical field of precision castings, in particular to a repairing device for post-processing of castings. Background Art

[0002] Casting is the most widely used metal liquid forming process. It is a method of pouring liquid metal into the mold cavity and obtaining a blank or part of a certain shape after it cools and solidifies. There are many steps in metal liquid forming and it is difficult to control accurately, which makes the quality of castings unstable. It is usually necessary to repair the metal castings after they are formed.

[0003] In the current prior art, when repairing cast metal parts, in order to improve the repair effect, it is usually necessary to grind the surface of the repaired part of the metal casting and then use the same material as the metal component to fill and repair.

[0004] The existing finished castings are relatively simple to grind and repair their surfaces, but the repair and grinding of the interior of pipe-type castings is more troublesome. In order to improve the subsequent repair effect, it is usually necessary to grind the repaired part first. The existing repair device has complicated grinding steps for pipe-type castings, poor processing efficiency, and poor use effect. Therefore, a repair device for post-processing of castings is proposed to solve the above problems. Utility Model Content
