Precision shaping die for forge piece for outer ring of automobile hub

Abstract

The invention discloses a precision shaping die for a forge piece for an outer ring of an automobile hub. The precision shaping die comprises a bottom board and an upper die. One side of the upper surface of the bottom board is equipped with a control switch. An input end of the control switch is electrically connected with an output end of an external power supply. A lower die is arranged in themiddle of the upper surface of the bottom board. The lower outer surface of the lower die is equipped with an electromagnetic induction heater. An input end of the electromagnetic induction heater iselectrically connected with an output end of the control switch. The interior of the lower die is equipped with a die cavity. The lower surface of the upper die is provided with a die cover matching the die cavity. Support columns are arranged at four corners of the lower surface of the bottom board. The base is arranged at bottom ends of the four support columns. An ejection mechanism is arrangedon the upper surface of the base. The precision shaping die for the forge piece for the outer ring of the automobile hub is convenient to use. The upper die and the lower die are prevented from beingvertically shaped not on the same plane during production. The electromagnetic induction heater can heat the lower die at higher speed, which is convenient for hot forging. The forge piece is quicklyto eject out and convenient to machine and produce.

Description

technical field [0001] The invention relates to the technical field of forming dies, in particular to a precision forming die for forgings of an outer ring of an automobile wheel hub. Background technique [0002] The outer ring of the automobile wheel hub bearing is installed on the edge of the automobile wheel, and works together with the inner ring to play a role in power transmission and support. It is an important safety part on the automobile and is very important for the safe driving of the automobile. The processing method of the outer ring of the automobile wheel hub bearing is hot forging. The existing precision forming dies for the forgings of the outer ring of the automobile wheel hub do not have a heating function. The forgings to be processed need to be heated before processing, which requires additional heating equipment. Dies are easy to shift during die fitting, resulting in reduced forging precision, and it is not easy to take out the forging after the forg...

The processing method of the outer ring of the automobile wheel hub bearing is hot forging. The existing precision forming dies for the forgings of the outer ring of the automobile wheel hub do not have a heating function. The forgings to be processed need to be heated before processing, which requires additional heating equipment. It is easy to shift when the mold is matched, which leads to the reduction of forging precision, and it is not easy to take out the forging after the forging is completed
