Description
Technical field
The present invention relates to diel field, in particular to a kind of drawing punching hole composite die.
Background technology
Drawing, also claims drawing, drawing, calendering etc., refers to and utilize mould, the definite shape plate blank obtained is struck out various open hollow part or open hollow blank is reduced diameter, increase a kind of mechanical processing technique of height after stamping-out.Tubular, stairstepping, taper, spherical, cell type and other erose thin-walled parts can be manufactured with deep-drawing technique.To process the part having through hole bottom tubular, conventional method is the processing being completed part by deep-drawing technique and punching technology two techniques, needs to reorientate, can not ensure the positional precision of machining hole in punching technology.Processing work has consuming time, less economical shortcoming by two techniques.
Summary of the invention
The object of the present invention is to provide a kind of drawing punching hole composite die, to improve the problems referred to above.
The present invention is achieved in that
A kind of drawing punching hole composite die, comprise upper bolster, die shoe, die shank, guide pin bushing and guide rod, described die shank and guide pin bushing are all connected on described upper bolster, described guide rod is fixedly connected on die shoe, the other end is placed in described guide pin bushing, the lower surface of described upper bolster is provided with drawing punch, upper surface and the described drawing punch correspondence position of described die shoe are provided with drawing die, piercing punch is provided with in described drawing die, described piercing punch is connected on described die shoe, described drawing punch is provided with punching concave die with described piercing punch correspondence position, the upper surface of described piercing punch is lower than the upper surface of described drawing die.
Drawing punch in the technical program can be connected directly between on upper bolster, also can be connected on upper bolster by other connectors.To ensure that drawing workpiece out has higher form accuracy and dimensional accuracy, then must ensure that the die hole in drawing punch and drawing die has higher positional precision, therefore, the connection of the connection of drawing punch and upper bolster, drawing die and die shoe all needs to locate, locate mode has a variety of, the locate mode of such as Position with One Plane and Two Holes also can be other locate mode.In addition, punching concave die can be directly the drawing punch that bottom has hole, can certainly be arranged at punching concave die independent in drawing punch.Owing to being provided with piercing punch in drawing die, in drawing punch, be provided with punching concave die, in the process of drawing processing completing workpiece, complete the punching processing of workpiece, the drawing processing of workpiece and punching processing complete in an operation, ensure that machining accuracy, save processing cost.
Further, the first movable panel is provided with in described drawing die, described first movable panel can move up and down in drawing die, the upper surface of described first movable panel is higher than the upper surface of described drawing die, described first movable panel is placed on described piercing punch, is provided with the first elastic component between described first movable panel and described die shoe.
Complete workpiece drawing processing and punching processing after, workpiece likely can drop in drawing die, for the workpiece after ensureing processing can take out fast and effectively in drawing die, in drawing die, arrange the first movable panel, the workpiece in drawing die can be released by the first movable panel under the effect of the first elastic component.For ensureing that the first movable panel is not ejected drawing die by the first elastic component, corresponding position limiting structure can be set on drawing die and the first movable panel, certainly, also can be ensured that by the length controlling the first elastic component the first movable panel is not ejected.
Further, the second movable panel is provided with in described punching concave die, described second movable panel can move up and down in punching concave die, described second movable panel bottom surface is lower than described drawing punch bottom surface, and described die shank top offers blind hole, is provided with limiting plate in described blind hole, connecting rod is provided with between described second movable panel and described limiting plate, described blind hole top offers internal thread, and described blind hole top is bolted with stop screw, is provided with the second elastic component between described stop screw and described limiting plate.
After punching processing completes, the waste material produced in punch process will rest in punching concave die, for ensureing that waste material can take out fast and effectively in punching concave die, second movable panel is set in punching concave die, waste material in punching concave die, under the effect of the second elastic component, takes out by the second movable panel.Certainly, if drawing die long enough, also can offer blind hole at the top of drawing die, limiting plate, the second elastic component and stop screw are arranged in the blind hole offered at drawing die top.
Further, described upper bolster lower surface is provided with the first fixed head, can by described die shank axial restraint after described first fixed head is fixedly connected with described upper bolster, and described drawing punch is connected on described first fixed head.
First fixed head mainly plays fixing die shank and the effect being connected drawing punch, and the first fixed head and upper bolster are located, clamp the rear positional precision that just can ensure drawing punch.The bottom surface of die shank directly contacts with the end face of the first fixed head, directly can be delivered on drawing punch by the first fixed head, this avoid upper bolster and be subject to stamping press after die shank is subject to stamping press.
