Laterally offer two relative push-rod holes on the wall as the pipeline of punched scrap passage, the sliding push rod that is movably installed in the described dowel hole passes this two push-rod hole;
Also comprise the stretching die socket, its upper surface is fixedly connected with the stretching die; The stretching die is positioned at flanging mould below; Stretching die socket lower end is fixed with lower table; The guide pillar that also comprises setting parallel to each other more than two, punching die holder are fixed in described guide pillar upper end; Guide pillar is slidingly mounted in the guide pin bushing, and guide pin bushing is fixed on the described lower table;
The upper end of punching die holder is connected with piercing punch, and the lower end of punching die holder is fixedly connected with extension bar, and the below of this extension bar is connected with down oil cylinder.
Good effect of the present invention is: drawing and forming, punching, the material returned operate on same the equipment and finish, the automaticity height, and the production efficiency height, occupation area of equipment is little.Effectively avoided the secondary location of end socket, and overcome because of being forbidden the quality instability problem and the high problem of percent defective that cause in the secondary location.
(4), description of drawings
Fig. 1 is a structural representation of the present invention.
(5), the invention will be further described below in conjunction with specific embodiment for the specific embodiment.
As Fig. 1, this example comprises the entablature that is used to connect the hydraulic press master cylinder and drives lower edge hydraulic press guide pillar slip lifting at master cylinder.Entablature is provided with tapered bar 1, and the lower end of tapered bar 1 has one 45 ° inclined-plane.The entablature lower end is fixedly connected with upper bolster 2, and upper bolster 2 lower ends are connected with stretching convex die 25 by dowel and hold-down screw 6, and center, stretching convex die 25 lower end offers a space, and is fixed with punching concave die 10 in this space.
This example also comprises the moved cross beam 5 that is used to connect the hydraulic press auxiliary oil cylinder and drives lower edge hydraulic press guide pillar slip lifting at auxiliary oil cylinder.Offer through hole on this moved cross beam 5, described dowel, hold-down screw 6 and stretching convex die 25 are passed this through hole of moved cross beam 5.Be fixedly connected with flanging mould 7 in the lower end of moved cross beam 5.Be provided with the pipeline as the punched scrap passage in stretching convex die 25, this pipeline lower end is positioned at the top of punching concave die 10.Physical location center, described stretching convex die 25 lower end offers a through hole, this through hole be positioned at punching concave die 10 directly over, the upper end of this through hole is communicated with above-mentioned pipeline lower end as the punched scrap passage.
