The utility model adopts the structural design of adding the groove on the die, increases the stress surface of the forging die, avoids the concentration of external stress, prevents the die from cracking and prolongs the service life of the die; by transferring the impact-bearing surface to the end surface of the die, the impact-bearing surface can be renovated along with the die without separate maintenance, thereby reducing the maintenance cost.
Description
Technical Field
The utility model relates to a mold processing technical field of automobile wheel hub bearing especially relates to a forging mould of automobile wheel hub bearing inner race.
Background
The automobile hub bearing mainly comprises components such as a shaft wheel (inner ring), an outer wheel (outer ring), a steering knuckle, a bearing and the like. The automobile hub bearing is assembled with a wheel for use. At present, an automobile hub bearing outer ring is processed and manufactured through a forging process, and the following defects exist during the processing of a forging die: the impact-bearing surface of the forging die is arranged on the die sleeve, so that the die is easy to crack; the impact bearing surface on the die sleeve can not be renovated in time, and needs to be maintained independently, so that the maintenance cost is increased; and the mold cannot ensure that the product size is within the design range.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a forging mould of automobile wheel hub bearing inner race just in order to solve above-mentioned problem.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
a forging die for an automobile hub bearing outer ring comprises an upper die holder and a lower die holder, wherein a base plate and an upper die are sequentially arranged at the bottom of the upper die holder from top to bottom, the upper die is fixedly connected with the upper die holder through an upper die pressing ring, an upper die core is arranged at the central position of the upper die, a lower die and a base plate are sequentially arranged at the top of the lower die holder from top to bottom, the lower die is fixedly connected with the lower die holder through a lower die pressing ring, a die cavity is formed in the lower die, a lower die core is arranged at the position, corresponding to the upper die core, of the center of the; the end face of the upper die and the end face of the lower die are planes, the end faces of the upper die and the lower die are attached to each other, and grooves are formed in the lower die.
Preferably, the cross-section of the groove is approximately "J" shaped.
Preferably, the grooves are distributed annularly on the end face of the lower die.
Preferably, the upper die pressing ring is fixedly connected with the upper die base through a bolt, and the lower die pressing ring is fixedly connected with the lower die base through a bolt.
The beneficial effects of the utility model reside in that: the utility model adopts the structural design of adding the groove on the die, increases the stress surface of the forging die, avoids the concentration of external stress, prevents the die from cracking and prolongs the service life of the die; by transferring the impact-bearing surface to the end surface of the die, the impact-bearing surface can be renovated along with the die without independent maintenance, thereby reducing the maintenance cost; the die ensures that the size of the product is within the design range, and is beneficial to the final forming of the forge piece.
