Operation principle of the present invention is as follows: describe below in conjunction with the specific implementation process of accompanying drawing to this invention.
1) reset condition: oil cylinder piston also is in upper position with piston rod 3 by the brisement wedge 5 that contiguous block 4 connects at upper position, and present relaxed state, no interaction force between brisement wedge 5 and little slide unit ringfeder 12 and the big slide unit ringfeder 13 this moment.Electromagnet 7 is not switched on, and big slide unit 15 and little slide unit 10 are close to back-up block 9 left at back pressure spring 21a under the effect of 21b.
2) electromagnet 7 energisings, by push rod 8 little slide unit 10 is reached the big slide unit of being close to little slide unit 10 15 and push away ejector pin back-up block 9 to right-hand mobile, put into connecting rod 14, its large and small hole is inserted in the major part pin and the microcephaly that are made up of little slide unit ringfeder 12, big slide unit ringfeder 13 respectively and sold in 16.Brisement wedge 5 is slidingly connected with T type, dove-tail form or other form with contiguous block 4, and brisement wedge 5 can move horizontally with big slide unit 15 and little slide unit 10.
3) electromagnet 7 outages, spring 21a, 21b promote big slide unit 15 and then promote little slide unit 10 to shift to ejector pin back-up block 9, two of connecting rod cap shoulder face 25a on slide unit, 25b meets ejector pin 11a, 11b.Brisement wedge 5 also moves with big slide unit 15 and little slide unit 10.
4) oil cylinder piston is downward fast, downward by piston rod 3 pulling wedges 5, utilize the wedge type reinforcement principle, apply outside active force, make connecting rod 14 be fractured into gonnecting rod body and connecting rod cap two parts along the stress groove by little slide unit ringfeder 12, big 13 pairs of connecting rod 14 big end holes of slide unit ringfeder.Brisement wedge 5 ramp effect make gonnecting rod body move with big slide unit 15 in the big slide unit ringfeder 13 with inclined-plane, separate with connecting rod cap.Because little slide unit ringfeder 12 cooperates to face directly with brisement wedge 5, therefore brisement wedge 5 does not move downward and directly little slide unit ringfeder 12 is produced transverse component, so little slide unit 10 holding positions are motionless, this moment, brisement wedge 5 and piston rod 3 and being fixed between the contiguous block 4 on the piston rod do not relatively move.
5) brisement wedge 5 moves upward with oil cylinder piston bar 3, unclamps with little slide unit ringfeder 12, big slide unit ringfeder 13, and big slide unit 15 spring-loadeds reset, and are adjacent to little slide unit 10.
6) electromagnet 7 energising promotes little slide unit 10, and then promotes big slide unit 15 and move, and is fixed on big slide unit ringfeder 13 on the little slide unit 10 and promotes wedges 5 and move to same direction, and connecting rod cap shoulder emaciated face is taken off gonnecting rod body and lid from ejector pin 9.
7) repeat the 2-6 process.
For the different size connecting rod, can realize brisement processing by changing and adjust anchor clamps.Setting-up screw 18 can be adjusted the microcephaly and sell 16 positions, adapts to the different Machining of Connecting Rod of hole centre-to-centre spacing.Ejector pin 9 itself also is a nut, can the position of change own by tightening or unscrewing, and its spacing can be adjusted with the distance of different size connecting rod two shoulder faces.
