Horizontal rolling process and forming device for special-shaped ring piece

Abstract

The invention relates to the field of ring piece machining equipment, in particular to a horizontal rolling process and forming device for a special-shaped ring piece. The horizontal rolling process comprises the following steps that a blank is heated to the forging temperature and subjected to punch forming; a formed ring piece blank is moved to a working platform to be fixed; two opposite grinding wheels and two opposite pressing wheels are used for rolling an obtained workpiece blank; and flashes and burrs are removed. The forming device comprises the grinding wheels pressed on the side edge of a ring piece to be formed, the pressing wheels pressed on the side edge of the other side of the ring piece to be formed and arranged opposite to the grinding wheels, an operation platform used for placing the ring piece to be formed and driving the ring piece to rotate, and a support arranged on the operation platform and rotationally connected with the grinding wheels. By means of the design scheme that the edge of the pressing wheel is rolled by the rolling wheel to be warped consistently, the edge warping problem of the ring piece is effectively solved, and the quality of a finally-formed product is effectively improved; the replacement frequency of the support or the grinding wheel or the pressing wheel is reduced through an adjustable installation frame, meanwhile, the time for adjusting the support is saved, and operation is easy.

Description

Technical field [0001] The present invention relates to the field of loop processing equipment, in particular, to a horizontal rolling process and a molding apparatus of a shaped ring. Background technique [0002] The rolling technology is thermally treated with rolling technology and ultimately forms the desired shape. The traditional rolling process usually uses a single mill to proceed with a single roller, and the shape of the conventional rush is two heads and narrowness, which in turn leads to rolling, and then the raw phenomenon will result in a decrease in the product. [0003] In addition, the conventional roller has increased the stent of the support wheels as the number of uses, and thereby causing the gesture change of the mill (i.e., the side surface of the mill and the surface of the roller surface cannot be maintained), thus The quality of the molding product has to replace the new bracket or roller, and re-correction work, waste and cumbersome process.

AI Technical Summary

Problems solved by technology

The traditional rolling process usually uses a single rolling wheel for active rolling, and the shape of the traditional rolling wheel is the same width at both ends, which will cause warping of the ring after rolling, which will lead to a decrease in the yield rate of processing

[0003] In addition, with the increase of the number of times of use of the traditional roller, the bracket supporting the roller tends to deform to a certain extent, which leads to the change of the attitude of the roller (that is, the side of the roller cannot be kept parallel to the surface of the ring), thus Affect the quality of the formed product, have to replace the new bracket or roller, and re-calibrate the work, wasteful and cumbersome process
