Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting tooling, more particularly to a deformation-preventing tooling for a rotary body type casting. BACKGROUND

[0002] A rotary body type casting is prone to deformation during heat treatment. Currently, a pull bar is designed on the top or inner cavity of the casting, and the pull bar is cut off after heat treatment. However, if defects such as blowhole and shrinkage are present at the joint between the casting and the pull bar, the casting needs to be welded and then heat treated, and in severe cases, the casting needs to be scrapped. The operation is inconvenient, the efficiency is low, and the cost is high.

[0003] Therefore, it is an urgent problem for those skilled in the art to provide a deformation-preventing tooling for a rotary body type casting. SUMMARY

[0004] Therefore, the present application provides a deformation-preventing tooling for a rotary body type casting to keep the shape of the rotary body casting stable during heat treatment in a simple, efficient and non-destructive manner.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] A deformation-preventing tooling for a rotary body type casting comprises two support rings adapted to the inner cavity of the rotary body casting, a plurality of nuts and a plurality of screws. The two support rings are arranged in parallel and spaced apart. The two support rings are welded together by a plurality of nuts uniformly distributed in the circumferential direction therebetween, and the inner thread holes of each nut are distributed in the radial direction. Each screw is screwed from the inside to the outside on the corresponding nut, so that the extension end of the screw is in contact with the inner cavity of the rotary body casting.

[0007] By adopting the above technical solutions, the present application has the following beneficial effects:

[0008] The tooling is directly placed in the inner cavity of the casting. By adjusting the number of screwing turns of the screw in the nut, the screw extends in the radial direction to adjust the tightness of the contact between the screw and the casting, thereby supporting the casting and reducing the probability of deformation of the casting during heat treatment. The operation is simple, non-destructive, and can be reused, thereby reducing production costs and improving production efficiency.

[0009] Further, the tooling further comprises a plurality of pull bars. The two support rings are connected by a plurality of pull bars uniformly distributed in the circumferential direction therebetween, and the nuts and the pull bars are arranged alternately.

[0010] The above-mentioned further technical solutions have the beneficial effect that when the diameter of the inner cavity of the casting is too large, the strength of the two support rings can be increased.

[0011] Further, the diameter of the support ring is 100-1000mm, and the cross-sectional diameter of the support ring is 10-50mm.

[0012] Further, the diameter of the screw rod is 10-50mm, and the length of the screw rod is 15-500mm.

[0013] Further, the number of the nuts is 3-30, and the number of the screw rods is 3-30.

[0014] Further, the support ring is made of round steel. BRIEF DESCRIPTION OF DRAWINGS
