The driving motor is used to drive the eccentric cam assembly to move in the guide hole 511, thereby driving the active regularizing assembly 2 to reciprocate towards the hollow part 11.

[0045] In the embodiment, the frame 1 is fixedly connected with a mounting plate 18 on one side. The driving motor is installed below the mounting plate 18. The power drag plate 51 is slidingly connected to the side of the mounting plate 18 away from the driving motor. Specifically, the mounting plate 18 is fixedly connected with a guide sliding rail 182. The guide sliding rail 182 extends in the direction of the hollow part 11. The power drag plate 51 is slidingly connected to the guide sliding rail 182. The eccentric cam assembly comprises an eccentric cam 52 and an eccentric shaft 53. The eccentric cam 52 is connected to the output shaft of the driving motor. The eccentric shaft 53 is arranged on the eccentric cam 52.

The eccentric shaft 53 is connected with a bearing 531. The bearing 531 is rotatably connected to the guide hole 511. The driving motor drives the eccentric cam to rotate, thereby driving the eccentric shaft 53 to make eccentric circular motion, so that the bearing 531 rotates in the guide hole 511, driving the power drag plate 51 to convert the reciprocating motion along the guide sliding rail 182 into reciprocating motion along the guide sliding rail 182, thereby driving the regularizing assembly to reciprocate, so as to realize the regularizing function of the pole piece 8. Further, guide rail stops 183 are fixedly connected to both ends of the guide sliding rail 182. The guide rail stops 183 are used to limit the reciprocating distance of the power drag plate 51, so as to reduce the possibility of the power drag plate 51 being separated from the mounting plate 18 during reciprocating motion, effectively ensuring the reliability and stability of the driving operation.

[0046] The eccentric circular motion of the eccentric cam assembly is converted into the reciprocating linear motion of the power drag plate 51 along the guide slide rail 182, and is further converted into the reciprocating linear motion of the pushing slide plate 12 along the linear guide rail 15, the first follow-up slide plate 13 along the first guide rail 16, and the second follow-up slide plate 14 along the second guide rail 17, thereby realizing the beating and shaping action of the pole piece 8 in each direction. The structure is simple, and only one driving source is needed to realize the shaping of the pole piece 8 in each direction synchronously, thereby effectively reducing the complexity of the equipment, improving the shaping efficiency and shaping precision of the pole piece 8.

[0047] Further, the pole piece 8 blanking and shaping device further comprises a plurality of supporting members 7, and each supporting member 7 is uniformly and spacedly arranged at the bottom of the frame body 1.
