Abstract
A locking device for secondary draws stamping die, including the terrace die that sets up on the base, being located the blank holder around the terrace die, terrace die and blank holder top are provided with the pressure flitch, are provided with the die and connect the casting die ware on first cylinder on the pressure flitch, and the casting die ware is held including the locking end with the local die matched with terrace die of setting on the terrace die, is provided with the second cylinder on the blank holder, are provided with the inclined plane with casting die ware locking end matched with on its end connection's the locking ejector pad. The utility model discloses a set up the locking end parallel with terrace die end on the casting die ware, set up on the blank holder can horizontal migration the locking ejector pad, according to the motion condition of pressing flitch and blank holder, mutually supporting with locking ejector pad inclined plane in locking end inclined plane, makes the casting die ware obtain to lock effectively, has prevented advanceing or delaying the return of casting die ware, has guaranteed secondary stamping forming's normal clear, has improved the shaping qualification rate of work piece.
Description
Technical field
The utility model relates to the Stamping Die Technology field of automobile manufacture industry, especially relates to a kind of locking device for secondary drawing diel.
Background technology
Most press machine all has blocking function, in the time of the product of need of production secondary drawing, can realize by the blocking function of lathe self the time delay rising of air cushion. But for some more special press machines that there is no blocking function, in the time carrying out secondary mould punching and mould backhaul, easily cause workpiece deformation. Such lathe arranges punch on base, punch is around the blank holder that can move up and down, punch and blank holder top arrange holding pad, on this holding pad, be provided with die and carry out the pressing device that local punch forming is used, in the time carrying out punch forming, holding pad moves down, first pressing device contacts workpiece it is carried out to local punch forming, return gradually under cylinder action afterwards, holding pad continues to move down simultaneously, completes the overall punch forming of workpiece under the acting in conjunction of die and punch. But because existing mold does not arrange locking device, usually there is pressing device return in advance or the phenomenon of delaying. Return in advance, while carrying out two times punch, location is inaccurate, easily occurs substandard product; Be later than die return, under pressing device and die effect, easily cause deformation of products to scrap.
Summary of the invention
The utility model provides a kind of locking device for secondary drawing diel, and object is to make up the deficiency of the above-mentioned secondary drawing press machine without blocking function.
For achieving the above object, the utility model can be taked following technical proposals:
Locking device for secondary drawing diel described in the utility model, comprise the punch being arranged on base, be positioned at described punch blank holder around, described punch and blank holder top are provided with holding pad, on described holding pad, be provided with die and be connected in the pressing device on the first cylinder, the punch end that described pressing device comprises locking end and matches with the local die being arranged on punch, on described blank holder, be provided with the second cylinder, on the locking pushing block that its end connects, be provided with the inclined plane of matching with described pressing device locking end.
The locking device for secondary drawing diel that the utility model provides, on its pressing device, be provided with the locking end parallel with punch end, on blank holder, be provided with the locking pushing block that can move horizontally, according to the motion conditions of holding pad and blank holder, locking end inclined plane and locking pushing block inclined plane cooperatively interact, and make pressing device obtain locking effectively, prevented pressing device in advance or delay return, ensure normally carrying out of two times punch moulding, improved the moulding qualification rate of workpiece.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of A portion in Fig. 1.
Fig. 3 is the state diagram of the utility model each parts while carrying out two times punch moulding.
Detailed description of the invention
As shown in Figure 1, 2, locking device for secondary drawing diel described in the utility model, comprise the punch 1 being arranged on base, be positioned at punch 1 blank holder 2 around, punch 1 and blank holder 2 tops are provided with holding pad, on holding pad, be provided with die 3 and be connected in the pressing device on the first cylinder 4, the punch end 7 that pressing device comprises locking end 5 and matches with the local die 6 being positioned on punch 1, the second cylinder 8 is installed on blank holder 2, on the locking pushing block 9 that its end connects, is provided with the inclined plane of matching with pressing device locking end 5.
When use, first workpiece 10 is placed on punch 1 and blank holder 2, holding pad presses down, and first blank holder 2 contacts workpiece 10 is clamped with it, and continues to move down under the drive of holding pad, in folding process, the piston rod of the first cylinder 4 stretches out, and the punch end 7 of pressing device and the local die 6 of punch 1 are matched, and workpiece 10 is carried out to local punch forming, meanwhile, the scarf a1 of pressing device locking end 5 contacts with the scarf a2 of locking pushing block 9; Then, the piston rod of the second cylinder 8 stretches out gradually, promoting locking pushing block 9 moves right, under the cooperatively interacting of scarf a1 and a2, the horizontal movement of locking pushing block 9 is converted into the vertical lifting action of pressing device locking end 5, until the locking upper surface of pushing block 9 and the lower surface of pressing device locking end 5 are in contact with one another, the piston rod being connected with pressing device is all retracted, locking pushing block 9 is realized locking function, meanwhile, holding pad continues to press down, make die 3 gradually to punch 1 near and complete the overall punch forming (as shown in Figure 3) to workpiece 10. The rate of climb of pressing device is consistent with the decrease speed of die 3, and workpiece 10 is only contacted with pressing device punch end 7 in overall punch forming process, not only can carry out clamping and positioning but also can be due to compressive deformation. Afterwards, holding pad moves on the whole, when blank holder 2 is with after it separates, workpiece 10 can be taken out.
