For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of upper punch structure for continuous drawing or mould, comprise drawing and forming patrix and drawing and forming counterdie, at the drawing and forming counterdie piercing punch is installed, the drawing and forming patrix is installed the punching concave die of corresponding piercing punch, described drawing and forming counterdie is provided with punching and takes off the material piece and worn and mistake by piercing punch, it is by taking off the material spring by power transmission pin jack-up that the material piece is taken off in this punching, punching is taken off the material piece and is pressed down by punching concave die and piercing punch is stretched out and cooperatively interact and finish upper punch operation behind the drawing and forming during matched moulds, on the described drawing and forming, be provided with insufflation channel between the counterdie, this passage communicates with the punching die cavity and discharges outside mould through going out reject chute.
Further, described piercing punch passes punching and takes off the material piece, this punch bottom is installed in the drawing and forming counterdie by the punch fixed block, the power transmission pin passes the punch fixed block and withstands on the bottom surface that the material piece is taken off in punching, the power transmission pin is divided into rectangle and is taken off material spring and placing in the hole of drawing and forming counterdie, and it is fastening by stopping payment plug screw that this takes off material spring bottom.
Further, establish force-transmitting block and patrix spring on the described punching concave die, this spring places in the hole of drawing and forming patrix, and the spring top is fastening by stopping payment plug screw.
Further, described drawing and forming patrix comprises and takes off plate, and punching concave die places in the slotted eye that takes off plate, and is provided with the correcting pin at the drawing and forming patrix, and this correcting pin places the punching concave die front side and passes and takes off plate and stretch out.
Further, be provided with out reject chute between the upper and lower mould of described drawing and forming, it communicates with insufflation channel, and the insufflation channel outboard end is gas hole, its blowing method is that bottom dead centre is blown, and the drawing and forming patrix comes downwards to bottom dead centre when beginning to blow, and piercing punch is broken through the edge of a knife fully.
The present invention be applicable to stretch or moulding after need punching but be limited to the part of insufficient space punching downwards, be characterized in not changing under original stretching or the forming direction prerequisite, the intensity that changes punching direction assurance punching concave die realizes product and guarantees the stability that mould is produced.
The present invention has kept stable and putative forming direction, and has guaranteed the intensity of punching convex die to have solved simultaneously the problem of waste material discharge with the mode of blowing by the change of punching direction, has following advantage:
1. the direction of stretching and moulding is because the problem of punching is not influenced;
2. utilize existing space to do intensity and effective binder area that conversion has guaranteed the punching convex die;
3. the air blowing discharge guarantees the timely eliminating of waste material.
Description of drawings
Fig. 1 is die opening state schematic diagram of the present invention;
Fig. 2 is matched moulds view of the present invention;
Fig. 3 is the present invention's schematic diagram of blowing.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Embodiment: see also Fig. 1 to Fig. 3, a kind of upper punch structure for continuous drawing or mould, comprise drawing and forming patrix 100 and drawing and forming counterdie 110, at drawing and forming counterdie 110 piercing punch 5 is installed, the punching concave die 4 that drawing and forming patrix 100 is installed corresponding piercing punch 5, described drawing and forming counterdie 110 is provided with punching and takes off material piece 6 and worn and mistake by piercing punch 5, it is by taking off material spring 9 by power transmission pin 8 jack-up that material piece 6 is taken off in this punching, punching is taken off material piece 6 and is pressed down by punching concave die 4 and piercing punch 5 is stretched out and cooperatively interact and finish upper punch operation behind the drawing and forming during matched moulds, on the described drawing and forming, be provided with insufflation channel between the counterdie, this passage communicates with the punching die cavity and discharges outside mould through going out reject chute 11.
