a bearing ring shaping device comprises a bottom plate, a punch and a product backer for positioning a bearing ring, wherein the product backer is fixed on the bottom plate, when the bearing ring is positioned by the product through the mountain, the axis of the punch coincides with the central line of the long axis of the bearing ring, the bottom plate is provided with a punch driving mechanism, the punch driving mechanism is used for driving the punch to move along the axial direction of the punch, the punch driving mechanism comprises a cylinder, a swing rod and a swing shaft, the end part of the cylinder body of the cylinder is hinged with the bottom plate, the piston rod of the cylinder is hinged with one end of the swing rod, the swinging shaft is vertically fixed on the bottom plate, the swinging rod swings under the driving of the cylinder by taking the swinging shaft as an axis, the other end of the swing rod is integrally provided with a gear, a rack is fixedly arranged on the punch, and the gear is meshed with the rack.

Furthermore, a rack guide seat is fixedly arranged on the bottom plate, and the rack is in sliding fit with the rack guide seat.

Furthermore, one side of the product backer is provided with an arc surface used for being matched with the bearing ring.

Furthermore, handles are fixedly arranged on two sides of the bottom plate, so that the shaping device is convenient to carry.

The bearing ring shaping device can automatically impact the bearing ring product only by manually placing the product stably according to the requirement, and the impact force, the impact frequency and the impact time can be adjusted according to experimental statistical data; the product can be taken out for rechecking when reaching the set impact times and time, the operation is simple, a great number of micro-deformation products can be saved, the product continuously absorbs micro-deformation in the impact process, the original heat treatment stress is released, and the slight trace caused in the impact process of the product can be removed in the subsequent processing.

Compared with the prior art, the utility model has the advantages that the shaping of a plurality of different bearing outer rings can be realized by the device only within a certain outer diameter range, and different products only need to be replaced by different backer products; the product continuously absorbs micro deformation in the impact process, the original heat treatment stress is released, the rebound is small, the dimensional stability is good, the impact shaping efficiency on the oval bearing ring is high, and the shaping effect is good; and the device has simple structure and lower cost.
