Description

Technical Field

[0003] The above-mentioned device places the bearing to be processed into the placement hole so that the bearing to be processed contacts the magnet, and then controls the electric hydraulic rod to drive the first motor and the rolling roller to move downward, so that the first motor drives the rolling roller to rotate to expand the inner hole of the bearing to be processed. When the waste chips generated during the expansion process need to be cleaned, the second motor is controlled to drive the gear to rotate. Due to the meshing of the gear and the gear rod, the gear drives the fixed block and the cleaning shovel rod to move in the direction close to the blanking hole, so that the cleaning shovel rod shovels the waste chips into the blanking hole and drops them into the collection box. Under the mutual cooperation of the first motor, gear, gear rod, cleaning shovel rod and fixed block, the cleaning shovel rod smoothly cleans the waste chips into the collection box, further enabling it to have the function of automatically cleaning the waste chips, so that the waste chips generated during the expansion of the bearing ring do not need to be cleaned manually, and the cleaning efficiency is also improved.

[0004] However, the above-mentioned hole expanding device for bearing ring forging processing was found to have the following disadvantages during use: only magnets are provided in the fixing frame to adsorb and fix the bearing ring, which can easily cause the bearing ring to rotate during use, thereby failing to ensure the hole expanding effect of the bearing ring.
