Background technology
Deep groove ball bearing is one type the most common in the rolling bearing.The deep groove ball bearing of basic model is by an outer ring, and an inner ring, one group of steel ball and one group of retainer consist of.
In the high speed wabbler mechanism of deep groove ball bearing use on frame, the internal structure of its bearing is designed to full ball.In order to fill the technological requirement of ball, split the outer ring after mill processing in the outer ring of bearing again, allows steel ball install to the raceway the inside from the crack at the position of this opening.Before bearing ring quenches, the endoporus of lasso is opened one 60 ° sharp groove, become 25 ° of gradients with axial.The function of point groove is to concentrate at sharp corner formation stress after waiting quenching.Lasso is split in sharp groove location with specific purpose tool after finishing Deng operations such as the plane of bearing ring, external diameter, raceway groove, superfinishings.
Processing that at present should the point groove is gone back the neither one special equipment and is realized batch production, can only process this breach with the mode of line cutting.But the line cutting cost is high, is not suitable for batch production.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of bearing outer ring opening punch die is provided, sharp groove that can batch machining bearing outer ring opening, production cost is low, uses reliable.
According to technical scheme provided by the invention, bearing outer ring opening punch die comprises pressing mold upper plate, pressing mold lower plate, pressing mold guide pillar, the first screw, cutter pressing plate, cutter, the second screw, patrix, the 3rd screw and counterdie, the fixing a plurality of pressing mold guide pillars in pressing mold upper plate upper end, a plurality of pressing mold guide pillars are parallel to each other.The pressing mold upper plate is slidably mounted on a plurality of pressing mold guide pillars, it is characterized in that: pressing mold upper plate lower end connects patrix by the second screw, is provided with the cutter holes of up/down perforation in the patrix.The patrix side is threaded connection the first screw, the first screw front end fixed cutting tool pressing plate.Cutter pressing plate and cutter are arranged in cutter holes, and the cutter pressing plate is pressed on the cutter holes side with cutter.Counterdie is fixed on the pressing mold lower plate by the 3rd screw, and counterdie is positioned under the patrix.The patrix center is provided with blanking hole, and the lower end of blanking hole is communicated with the patrix side.Described blanking hole one side is provided with sharp groove.The patrix upper surface is provided with the first retainer plane, and the first retainer planar side is provided with the second retainer plane.
Be provided with the pressing mold guide pin bushing between described pressing mold upper plate and the pressing mold guide pillar.
Described patrix lower end is provided with guide body.
Be provided with the adjustment cushion block between described cutter and the cutter holes side.
The angle that described sharp groove both sides form is 60 °.
The plane included angle on described the first retainer plane and the second retainer plane is 90 °.
The angle of described the first retainer plane and horizontal plane is 25 °.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Sharp groove that can batch machining bearing outer ring opening, production cost is low; Use reliable.
