The utility model content
The technical problems to be solved in the utility model provides a kind of flat-die forging hydraulic press kicker cylinder cylinder bottom syndeton, can bear horizontal force, the danger of kicker cylinder dislocation or disengaging in the time of can stopping eccentric the forging.
For solving the problems of the technologies described above, flat-die forging hydraulic press kicker cylinder cylinder bottom syndeton of the present utility model, comprise the last concavo-convex ball pad combination that is loaded between kicker cylinder cylinder bottom and the sill ear seat, described recessed ball pad is arranged in the hole of kicker cylinder cylinder bottom, protruding ball pad is corresponding to be placed in the hole of sill ear seat upper surface, have a through hole on the described sill ear seat, be provided with the securing member that connects kicker cylinder and sill ear seat in the through hole, described securing member runs through concavo-convex ball pad combination from bottom to up.
Preferred in said structure, securing member is a trip bolt, and the screw rod upper end of screw screws in the kicker cylinder cylinder bottom, is provided with packing ring between screw head and the sill ear seat hole.
Preferred in addition, described syndeton also comprises the following concavo-convex ball pad combination of being located at sill ear seat below, and the protruding ball pad of described down concavo-convex ball pad combination is placed in the hole of sill ear seat lower surface, and described securing member runs through two concavo-convex ball pad combinations from bottom to up.
Preferred in said structure, described securing member is a double-screw bolt, double-screw bolt runs through down concavo-convex ball pad combination from bottom to up successively and goes up concavo-convex ball pad combination, the kicker cylinder cylinder bottom is stretched in the upper end of double-screw bolt, the recessed ball pad of down concavo-convex ball pad combination is stretched out in the lower end of double-screw bolt, supporting nut is equipped with in the lower end of described double-screw bolt, and the outer face of nut is provided with baffle plate, and described baffle plate and nut are fixed together by a plurality of screws.
Flat-die forging hydraulic press kicker cylinder cylinder bottom syndeton of the present utility model is simple, low cost of manufacture, and the effect that can bear horizontal force, the danger that kicker cylinder produces dislocation or breaks away from when having overcome eccentric the forging, functional reliability improves.
