Abstract

The invention relates to a flange forge piece and solves the technical problems that the precision of the existing flange forge piece is low and the like. The flange forge piece comprises a forge piece body, wherein the forge piece body comprises a conical shaft body; a first arched blind hole is formed in one end of the shaft body; a conical blind hole is formed in the other end of the shaft body; a second arched blind hole is formed in the bottom of the conical blind hole; the sizes of the first arched blind hole and the second arched blind hole are equal; the pore size of the conical blind hole is smaller than the pore size of the first arched blind hole; a conical platform body is arranged on the peripheral direction of the outer side of one end, provided with the conical blind hole, of the shaft body; a first step is formed between the conical platform body and the shaft body; a square body is arranged on the end part of the conical platform body; an annular body is arranged on one side, which is connected with the conical platform body, of the square body; four arc-shaped bosses are formed since the outer side of the annular body exceeds the outer side of the square body; the other side of the square body is provided with a cylinder which is coaxial with the shaft body. Compared with the prior art, the flange forge piece has the advantages that the precision is high, the quality of a finished product flange is easily maintained, and the intensity is high.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a flange forging. Background technique [0002] Flanges are also called flanges or flanges. Flanges are parts that connect pipes and pipes or valves to each other. They are connected to pipe ends. There are holes in the flange, and bolts make the two flanges tightly connected. Flanges in auto parts are used to connect the motor with the reducer, as well as the connection between the reducer and other equipment. Flanges have been widely used in cars, and there is a tendency to gradually expand their application in trucks; at present, the existing flanges are mainly made of flange forgings through precision turning, so the quality of flange forgings determines to a certain extent The quality of the processed flange, but there are common flange forgings: low structural strength, low precision, poor stability, which easily reduces the quality of the processed flange. [0003] In...
