Abstract
The utility model relates to a lifting mechanism, in particular to the lifting mechanism of a multi-station drawing die. The lifting mechanism of the multi-station drawing die comprises a lifting block of a lifting workpiece arranged on a blank holder of the drawing die in a vertically sliding mode, a pushing device used for pushing the lifting block to move and a limited block used for limiting the ascending stroke of the lifting block. Due to the arrangement of the lifting block and the pushing device on the blank holder, a drawing stamp on the workpiece caused by a lower die is avoided and product quality is guaranteed.
Description
Technical field
The utility model relates to a kind of lifting mechanism, relates in particular to the lifting mechanism that a kind of multistation draws mould.
Background technology
Multistation draws mould and comprises mobilizable patrix, fixing counterdie and be arranged between the two blank holder, processed product at first is placed on the blank holder and locatees, patrix is descending then draws operation, in the existing structure, by the lifting mechanism that is arranged on the counterdie product is lifted after the completion of processing, thereby handgrip extracting product is transported to it on blank holder of another station then.Because counterdie is a punch, the lifting mechanism that is provided with on counterdie must cooperate with the profile of counterdie, because the accuracy of manufacture is easy to draw trace in the generation of the surface of product, influences product quality.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of multistation to draw the lifting mechanism of mould, and it is simple in structure, can not produce product and draw trace, has guaranteed product quality.
For achieving the above object, multistation of the present utility model draws the lifting mechanism of mould, comprises the lifting piece of the lifting product on the blank holder that can slide up and down to be arranged on drawing die, the thrust unit that promotes this lifting piece motion and the limited block that limits the up stroke of this lifting piece.
As to qualification of the present utility model, also comprise on the patrix that is arranged on drawing die and when patrix is descending, drive the top nitrogen spring that this lifting piece moves down downwards, described thrust unit is the bottom nitrogen spring that is connected with the lifting piece.
As to qualification of the present utility model, the lifting piece is provided with the magnetic part of adhesive product.
As to qualification of the present utility model, on the lifting piece, be provided with guide plate with the blank holder sliding-contact.
Adopt technique scheme, its beneficial effect is as follows: by lifting piece and thrust unit are set, can avoid the draw trace of mould to product on blank holder, guarantee product quality, use nitrogen spring to promote the lifting piece, use reliably, cost is low, compact conformation; Magnetic part is set on the lifting piece can be attracted product, avoids it in the lifting process play to take place; The frictional force that guide plate can reduce the lifting piece is set, prolongs the service life of lifting piece.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is done further to describe in detail:
Fig. 1 is the schematic diagram that the utility model combines with blank holder;
Fig. 2 is a schematic diagram of the present utility model.
Among the figure: 1, blank holder; 2, lifting piece; 3, bottom nitrogen spring; 4, limited block; 5, top nitrogen spring; 6, magnetic part; 7, guide plate; 8, withstand voltage.
The specific embodiment
As shown in Figures 1 and 2, the lifting mechanism that multistation of the present utility model draws mould comprises lifting piece 2, the thrust unit that promotes these lifting piece 2 motions and the limited block 4 that limits the up stroke of this lifting piece 2 of the lifting product on the blank holder 1 that can slide up and down to be arranged on drawing die, thrust unit is the bottom nitrogen spring 3 that is connected with lifting piece 2, in blank holder 1, be provided with the groove that holds lifting piece 2, be provided with guide plate 7 around the lifting piece 2 with the groove sliding-contact of blank holder 1.Bottom nitrogen spring 3 promotes this lifting piece 2 and moves upward up to contacting with limited block 4, for it can be pressed down automatically, on patrix, be provided with top nitrogen spring 5, on lifting piece 2, be provided with withstand voltage 8 that to contact with top nitrogen spring 5, this top nitrogen spring 5 drives withstand voltage 8 of lifting piece 2 along with the descending of patrix, make lifting piece 2 be under pressure and move downward to profile and overlap with blank holder 1, when drawing when finishing, patrix moves upward, top nitrogen spring 5 disengages with withstand voltage 8, this moment, blank holder 1 moved upward, product is separated with counterdie, lifting piece 2 promoted products and separated with blank holder 1 this moment, so that handgrip grasps product, and excessive velocities when lifting piece 2 promotes products and the play influence location of causing product, the magnetic part of adhesive product is set on lifting piece 2, this magnetic part can adopt permanent magnet or electromagnet, is that product guarantees to combine with lifting piece 2, is difficult for dislocation.
Claims (4)
1. a multistation draws the lifting mechanism of mould, it is characterized in that: comprise the lifting piece (2) of the lifting product on the blank holder (1) that can slide up and down to be arranged on drawing die, the thrust unit that promotes this lifting piece (2) motion and the limited block (4) that limits the up stroke of this lifting piece (2).
2. multistation according to claim 1 draws the lifting mechanism of mould, it is characterized in that: comprise also on the patrix that is arranged on drawing die and when patrix is descending, drive downwards the top nitrogen spring (5) that this lifting piece (2) moves down that described thrust unit is the bottom nitrogen spring (3) that is connected with lifting piece (2).
3. multistation according to claim 2 draws the lifting mechanism of mould, it is characterized in that: lifting piece (2) is provided with the magnetic part (6) of adhesive product.
