Problems solved by technology

In the production process of this retaining ring manufacturing process, there are the following disadvantages: First, in the flaring or forming process, the upper edge of the workpiece is extended and thinned due to flaring or forming, so that the weld is easy to crack, resulting in a high scrap rate of the process , and the manufacturing cost is relatively high; the second is that the surface quality of the workpiece is poor due to serious scratches

Abstract

The invention discloses a manufacturing process for a shield ring for a wheel type engineering machinery wheel and a special mould, and belongs to the technical field of engineering machinery. The manufacturing process comprises the following working procedures: heating, in which an annular ring blank is heated to be between 700 and 900 DEG C to form a heating workpiece; necking, in which the heating workpoece is subjected to necking and pressing by using a necking mould to prepare a necking workpiece; and forming, in which the necking workpiece is subjected to forming and pressing by using a forming mould to prepare a finished shield ring. The special mould comprises an upper mould body and a lower mould body, and the upper mould body comprises a necking upper mould body and a forming upper mould body. The manufacturing process and the special mould are applicable to manufacturing the shield ring for the wheel type engineering machinery wheel.

Description

technical field [0001] The invention relates to a manufacturing process of a retaining ring and a special mold thereof, in particular to a manufacturing process of a retaining ring for a wheel of a wheeled engineering machinery and a special mold thereof, belonging to the technical field of engineering machinery. Background technique [0002] At present, the manufacturing process usually used for wheel retaining rings of wheeled construction machinery is: blanking→rolling→welding→grinding→heating→flaring→forming; among them, the circular workpiece polished after welding is heated through expanding The mouth die is made into a truncated cone shape, and then the forming die is used for forming processing to obtain the finished retaining ring. In the production process of this retaining ring manufacturing process, there are the following disadvantages: First, in the flaring or forming process, the upper edge of the workpiece is extended and thinned due to flaring or forming, so...
