Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 2, a kind of double action press drawing die technique provided by the invention, this technique comprises the following steps,
S1, prepare Bear-grudge to be processed material, and Bear-grudge material is fixed on a double action press drawing die, locate by backstay 8;
S2, start double action press, the patrix of double action press drawing die with respect to the descending process of counterdie in, first upper blank holder 2 clamps blank surrounding with lower blank holder 3;
S3, patrix continue descending with respect to counterdie, and upper blank holder 2 keeps clamping blank surrounding with lower blank holder 3, and punch 6 is descending with respect to die 7, and blank inner chamber 101 is carried out to die mould;
S4, the relative counterdie of patrix all remain on die mould state in a setting-up time;
S5, patrix are up, and punch 6 is separated with die 7, and upper blank holder 2 separates with lower blank holder 3;
The ejection cylinder of S6, double action press is up, by top on stripper 9, stripper 9 pushing-off products 10;
S7, take out finished product 10, process finishing from double action press drawing die.
The present invention adopts the patrix of double action press drawing die with respect in the descending process of counterdie, after upper and lower blank holder (2,3) clamping blank surrounding, punch 6 moves down with die 7 and coordinates single cavity die, has advantages of that technique is simple, working (machining) efficiency is high and processing cost is low for existing independent processing.
Consult shown in Fig. 3, double action press drawing die comprises upper die and lower die, patrix comprises a upper blank holder 2 being connected with cope match-plate pattern 1, cope match-plate pattern 1 and upper blank holder 2 middle parts offer respectively mutually concentric first, the second through hole (11, 21), in the second through hole 21, be provided with a punch 6 that can move up and down along this second through hole 21, the outer wall of this punch 6 coordinates guiding with the second through hole 21 inwalls, on counterdie, be provided with blank holder 3 with upper blank holder 2 position opposite positions, on counterdie, be provided with a die 7 with punch 6 position opposite positions, die 7 is all installed on lower bolster 5 with lower blank holder 3.Punch 6 is installed in the second through hole 21, can move up and down along the second through hole 21, so, upper blank holder 2 can be asynchronous with the stroke that presses down of punch 6, first lower blank holder 3 clamps the fixing blank of blank surrounding with lower blank holder 3, also prevent the distortion of blank surrounding, punch 6 presses down one-shot forming blank inner chamber 101 together with die again, and technique is simple, working (machining) efficiency is high.
In the present embodiment, between lower blank holder 3 and lower bolster 5, be also provided with a packing ring 4, and lower blank holder 3 offers respectively the 3rd, the 4th mutually concentric through hole (31,41) with packing ring 4 middle parts, and die 7 is installed in the 3rd, the 4th through hole (31,41).Preferably, the first through hole 11 diameters are greater than the second through hole 21 diameters, and the size of the 3rd, the 4th through hole (31,41) is identical.Because punch 6 need to move up and down, when so the first through hole 11 is greater than described the second through hole 21, punch 6 can enter the second through hole 21 from the first through hole 11 easily, the second through hole 21 is again for guiding and location punch 6, and when on punch 6, move to the first through hole 11 when interior positional precision do not need very high yet.Because die 7 does not need to move up and down, so when die 7 is arranged in the 3rd through hole 31 and the 4th through hole 41, by the 3rd, the 4th through hole (31,41) location, positional precision is high.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present invention, all should be within protection scope of the present invention.
