Description

Unloading supporting device of quenching die for inner ring of aligning roller bearing Technical Field The utility model belongs to the technical field of bearing heat treatment, and relates to a die unloading supporting device for a quenching die of an inner ring of a self-aligning roller bearing. Background The method comprises the steps of carrying out secondary quenching on the bearing inner ring made of carburizing steel, carrying out secondary quenching on the bearing inner ring, and removing the mould to carry out subsequent flow, wherein the ferrule is contracted to be tightly attached to the mould after secondary quenching, the mould is lifted by a lifting tool, the mould is knocked by only two points clamped by a clamping tool during demoulding, the mould is knocked by using a knocking tool, the mould is required to be knocked off for a long time, the labor intensity is high, the larger the ferrule size is, the tighter the mould is, the more difficult and time-consuming to knock are, and the production efficiency is seriously affected. Meanwhile, the hanging air impact difficulty is high, the operation requirement on personnel is extremely high, and the impact drop point is slightly inaccurate, so that the product can be accidentally injured, and the product is collided with waste products. Disclosure of utility model The utility model provides a die-unloading supporting device of a quenching die for an inner ring of a self-aligning roller bearing, which supports a flange part in the inner ring along the circumferential direction of a ring by clamping jaws, can solve the problem that the die-unloading of the bearing ring is difficult after secondary quenching, reduces the labor intensity of operators, saves time, is convenient and quick, and reduces product knocks possibly caused by repeated striking. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The die unloading supporting device of the quenching die for the inner ring of the self-aligning roller bearing is provided with a plurality of clamping jaws used for supporting the middle baffle edge of the inner ring of the self-aligning roller bearing, the upper ends of the clamping jaws are bent to one side to form a supporting table used for supporting the middle baffle edge, the lower ends of the clamping jaws are bent to one side to form a fixing table used for fixing a chassis, the inner ring of the self-aligning roller bearing is supported on the chassis through the clamping jaws, the chassis is a circular disc with a through hole in the middle part, the chassis is provided with a plurality of sliding grooves which are in one-to-one correspondence with the clamping jaws, screws capable of moving in the sliding grooves are arranged corresponding to the sliding grooves, and the upper ends of the screws correspond to the screw holes on the fixing table to form the screw sliding and then are fixedly connected with the clamping jaw which is supported on the middle baffle edge. The chassis is provided with a plurality of hanging rings which are used for being conveniently hung, and the plurality of hanging rings are uniformly distributed along the circumference. The die unloading supporting device for the quenching die of the inner ring of the self-aligning roller bearing uses the clamping jaw as a supporting point to support the inner ring of the self-aligning roller bearing, a plurality of supporting points enable the die to be knocked down smoothly, the labor intensity of workers is greatly reduced, the die unloading efficiency is improved, on the other hand, the device enables the ferrule sleeved with the die to be stably located on the chassis, the unsafe factors of the previous suspending operation and the condition that the knocking surface is not easy to be precisely hit are avoided, the collision of products is reduced, the size of the opening caliber of the clamping jaw can be adjusted according to the size of the outline dimension of the middle baffle edge of the inner ring, and the purpose of supporting the middle baffle edge of the inner ring with different sizes can be achieved by using one supporting device, so that the die unloading purpose is achieved.
