Further, described spherical cavity diameter is greater than the diameter of described steel ball.The working face position of steel ball is sphere, when contacting with the retainer semi-finished product, must guarantee that steel ball exposes high dimensionally stable, and the quality in retainer pocket hole meets standard during with definite punching press; The diameter of steel ball is less than the diameter of spherical cavity, so that steel ball can rotate arbitrarily between steel ball seat and correcting die, the surface of steel ball is not fixed on the working face, has increased its service life.
Further, as preferably, the diameter of described steel ball 〉=10 ㎜.According to the standard of different retainers, the diameter of steel ball remains on more than 10 ㎜, guarantees that self pocket curvature accuracy reaches the high-caliber while, so that the wave type retainer pcketing that processes reaches the process requirement, the pocket hole is full.
Further, also comprise the stripper that is slidingly arranged on the steel ball seat, described stripper is connected with described backing plate by stop screw.After the retainer trimming is finished, retainer may with the adhesion of steel ball seat phase, when the pressure slider machine moves upward, be arranged on the stripper of backing plate below under the effect of self gravitation, the retainer on the steel ball seat is returned, finish material returned operation.
Further, also comprise stem, centring ring and locating dowel, described stem passes centring ring and described correcting die is flexibly connected, and locating dowel links to each other with described backing plate.Adding long spiro nail is connected and fixed centring ring, stem and steel ball seat.The retainer semi-finished product that have been shaped are placed on the correcting die of die shoe, upper bolster moves down, stem guiding position carries out positioning in the pilot hole of correcting die, upper bolster continues to move down, under the acting in conjunction of stem, steel ball, the material returned, correcting die, under the acting in conjunction of steel ball and correcting die, retainer is extruded ball-and-socket.
Further, also comprise the spring that is arranged between upper bolster and the backing plate.In the process of retainer shaping, can produce larger impulsive force between upper bolster and the steel ball seat, be provided with backing plate between the two, common backing plate can reduce the service life under the high-frequency shock environment, and further cushion between backing plate and upper bolster by compressing to make at the spring between backing plate and upper bolster, reduce impulsive force.
The present invention compared with prior art, have following advantage and a beneficial effect:
1 the present invention includes upper bolster, die shoe, backing plate and correcting die, described correcting die is connected with the die shoe bolt, described backing plate is connected with the upper bolster screw, also comprise steel ball and steel ball seat, described steel ball seat is connected with described backing plate bolt, described correcting die is provided with semi-round ball concave surface A, described steel ball seat is provided with semi-round ball concave surface B, semi-round ball concave surface A and semi-round ball concave surface B form spherical cavity, and described steel ball places spherical cavity, its good stability, rational in infrastructure, the product that processes satisfies technological requirement, reduces time of mid-stop, has improved operating efficiency.
The diameter of 2 steel balls of the present invention is less than the diameter of spherical cavity, so that steel ball can rotate arbitrarily between steel ball seat and correcting die, the surface of steel ball is not fixed on the working face, has increased its service life.
3 the present invention are according to the standard of different retainers, and the diameter of steel ball remains on more than 10 ㎜, guarantee that self pocket curvature accuracy reaches the high-caliber while, so that the wave type retainer pcketing that processes reaches the process requirement, the pocket hole is full.
