Description
Technical field
The utility model relates to a kind of drawing die, is specifically related to a kind of mould that workpiece is carried out to blanking, stretching.
Background technology
In prior art, while utilizing stretching principle machining sheet goods to make it have special shape, first need to carry out blanking operation through blanking die unnecessary material is removed, obtain the blank of required outline with this, and then workpiece is carried out to drawing and forming, will cause so at least using two moulds, need two operations, not only production cost is high, and manufacturing procedure is many, production efficiency is low, also can increase the input of manpower simultaneously.
Utility model content
For above-mentioned weak point of the prior art, the utility model aims to provide one both can realize blanking, can realize again the hood drawing die of stretching, had not only saved upper product cost, and had reduced manufacturing procedure.
For solving the problems of the technologies described above, the utility model provides a kind of drawing die, comprise base plate and head, described base plate is fastened on work bench of punch press by bolt and pressing plate, and punch retainer is housed on base plate, die shank is housed in head, the lower end of die shank is connected to die block, it is characterized in that: punch retainer is provided with punch stripper, between punch retainer and punch stripper, is provided with spring, the lower end of die block is connected to add-in card, and the lower end of add-in card is connected to stretching concave template.
In punch retainer, be provided with punch.
Punch stripper is connected with punch retainer by guide pillar.
Stretching concave template is fixed by screws in below die block.
Described stretching concave template is also connected to knockout rod, and described knockout rod is through flitch on die shank, mould bases, and add-in card and stretching concave template join.
The beneficial effects of the utility model are: the utility model is simple in structure, and clamping mould, on punch press, can be carried out to stretching and punching to part to be processed, disposable shaping, and can complete blanking simultaneously, and simple to operation, improve operating efficiency.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
A kind of drawing die, comprise base plate 6 and head 12, described base plate 6 is fastened on work bench of punch press 5 by bolt 2 and pressing plate 1, punch retainer 7 is housed on base plate 6, die shank 13 is housed in head 12, the lower end of die shank 13 is connected to die block 10, it is characterized in that: punch retainer 7 is provided with punch stripper 8, between punch retainer 7 and punch stripper 8, be provided with spring 3, the lower end of die block 10 is connected to add-in card 11, and the lower end of add-in card 11 is connected to stretching concave template 9.
In punch retainer 7, be provided with stretching convex die 4.
Punch stripper 8 is connected with punch retainer 7 by guide pillar 15.
Add-in card 11 is fixed by screws in below die block 10.
In stretching concave template 9, be provided with stretching die 16.
When work, on stretching die 16, put, stretching convex die 4 underlyings, processed raw material is placed on punch stripper 8 and is fixed, along with head 12 moves down, drive die shank 13 to move down, the downward matched moulds punching press of concave template 9 makes to stretch, the concave template 9 that stretches when matched moulds is depressed punch stripper 8, makes to reveal in stretching convex die 4, and plate is sent into stretching die 16 internal shapings; When die sinking resets, hit the part pushing away after completion shape by knockout rod 14, be convenient to fetch; Meanwhile, the elastic force effect of spring 3, upwards lifts stripper 8, makes plate come off out from stretching convex die 4, completes the disposable stamping of part, can carry out next circulation punching press.
