Abstract

The utility model relates to a die structure for product drawing forming, in particular to a blank drawing die. The blank drawing die is provided with a female die, a male die corresponding to the female die, and a blank holder positioned between the female die and the male die, wherein primary buffer support devices for supporting the blank holder are arranged on the male die; the female die pushes the blank holder to move down, and compresses the primary buffer support devices to complete the product drawing forming; and secondary buffer support devices for applying buffer support forces on the blank holder after the primary buffer devices are compressed and before the product drawing forming is completed are arranged on the male die. As the secondary buffer support devices are additionally adopted, the support forces suffered by the blank holder before the product drawing forming are increased, pressure suffered by the blank holder is increased adaptatively in order to balance the increased support forces, forming states of plates are changed in a drawing forming process of a metal plate piece, and resilience and distortion of the metal plate piece are prevented.

Description

The blanking and drawing die tool
Technical field
The utility model relates to a kind of mould structure to the product drawing and moulding, relates in particular to a kind of blanking and drawing die tool.
Background technology
in existing blanking and drawing die lamps structure, comprise die more, punch, blank holder between die and punch, a kind of drawing die with full nitrogen air cylinder type ejection pressing mechanism is disclosed as Chinese utility model patent CN202186070U, it has the punch that is placed on press bench, the forcing press top shoe, the die that is equipped with punch, be positioned at the blank holder of die below and be positioned at the thrustor of blank holder below, thrustor applies an active force to blank holder, it is opposite that this active force and forcing press top shoe drive the active force that in the descending process of die, blank holder is applied, thrustor is for applying the force application apparatus of cushioning effect power.Adopt this scheme, descending so that blank holder is exerted pressure at the forcing press top shoe, blank holder is exerted pressure to thrustor, complete the drawing and moulding to product after die and punch are meshed, in whole forming process, the support force that blank holder bears is provided by thrustor (as the lathe push rod) fully, and the pressure that is applied to blank holder comes from press machine fully, be invariable in the drawing and moulding process, therefore, sheet material easily deforms and distortion in forming process.
The utility model content
Be to solve the deficiencies in the prior art, the utility model provides a kind of can change pressure-pad-force in the drawing die forming process to improve the blanking and drawing die tool of plate forming state, has effectively prevented resilience and the distortion of sheet metal component.
For achieving the above object, blanking and drawing die tool of the present utility model, punch, the blank holder between die and punch with die, setting corresponding to die, be provided with the first-level buffer bracing or strutting arrangement that blank holder is supported on punch, described die promotes blank holder and moves down and compress the drawing and moulding of completing after the first-level buffer bracing or strutting arrangement product, being provided with on punch after the first-level buffer device is compressed, before the product drawing and moulding, blank holder is applied the level 2 buffering bracing or strutting arrangement of buffering support force.
As the restriction to aforesaid way, described level 2 buffering bracing or strutting arrangement is for connecting the nitrogen spring that is arranged on punch.
As the improvement to aforesaid way, described level 2 buffering bracing or strutting arrangement 9mm-11mm place before the tension and compression moulding applies the buffering support force to blank holder.
As the restriction to aforesaid way, described level 2 buffering bracing or strutting arrangement 10mm place before the tension and compression moulding applies the buffering support force to blank holder.
As the further restriction to aforesaid way, described level 2 buffering bracing or strutting arrangement along the length direction of punch arrange a plurality of.
As to restriction of the present utility model, described first-level buffer bracing or strutting arrangement is the lathe push rod.
Adopt as above technical scheme, its effect is as follows:
1, set up the level 2 buffering bracing or strutting arrangement, before having realized the product drawing and moulding, the suffered support force of blank holder becomes large, for balance should become large support force, the pressure that blank holder is subject to is adaptive increase also, and then when the sheet metal component drawing and moulding, change the completed state of sheet material, prevent resilience and the distortion of sheet metal component; The level 2 buffering bracing or strutting arrangement adopts nitrogen spring, and it is simple in structure, and stressed buffering is comparatively stable;
2, the level 2 buffering bracing or strutting arrangement is set to before the tension and compression moulding 9mm-11mm place blank holder is applied the buffering support force, especially 10mm place obtains effectively finalizing the design pressure before making product approval, after product is drawn, realize plastic deformation completely, reduce the distortion resilience of product;
3, the level 2 buffering bracing or strutting arrangement arranges a plurality ofly along the length direction of punch, makes blank holder be subject to equilibrium, stable support force, improves the fixed effect that draws of product.
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 utility model stereochemical structure disassembled form schematic diagram;
In figure: 1, die; 2, punch; 3, blank holder; 4, first-level buffer bracing or strutting arrangement; 5, level 2 buffering bracing or strutting arrangement.
The specific embodiment
The blanking and drawing die tool that the present embodiment relates to, by shown in Figure 1, it has die 1, punch 2, the blank holder 3 between die 1 and punch 2, blank holder 3 and first-level buffer bracing or strutting arrangement 4, wherein, die 1 setting corresponding to punch 2, and blank holder 3 can adopt existing drawing mold structure.Be provided with the first-level buffer bracing or strutting arrangement 4 that blank holder 3 is supported on punch 2, first-level buffer bracing or strutting arrangement 4 adopts existing lathe push rod, it is when supporting blank holder 3, and when being subject to the pressing down of die 1 on blank holder 3, the lathe push rod can move down together along with blank holder 3.
Be provided with level 2 buffering bracing or strutting arrangement 5 on punch 2, before the design philosophy of level 2 buffering bracing or strutting arrangement 5 is that product is finished by drawing and moulding, for blank holder 3 provides an extra buffering support force, the support force that blank holder 3 is subject to is increased, accordingly, in order to complete drawing and moulding, the pressure potential that blank holder 3 is subject to must correspondingly increase.In the present embodiment, level 2 buffering bracing or strutting arrangement 5 adopts nitrogen springs, and nitrogen spring be a plurality of along the length direction setting of punch 2.The height of nitrogen spring when nature be less than the height of lathe push rod when accepting blank holder 3 self gravitation, and specifically, during the 10mm place, nitrogen spring supports blank holder 3 before product is finished by drawing and moulding.
In use, the lathe push rod as first-level buffer bracing or strutting arrangement 4 supports blank holder 3, when die 1 moves downward with the lathe slide block, contacts with blank holder 3, and the product panel beating is clipped between die 1 and blank holder 3.Along with die 1 continue move down, blank holder 3 with contact in the 10mm place higher than the drawing and moulding position as the nitrogen spring of level 2 buffering bracing or strutting arrangement 5, at this moment, blank holder 3 provides support power simultaneously by nitrogen spring and lathe push rod, make the pressure that blank holder 3 is subject to improve, until the support force that die 1 is pressing blank holder 3 to overcome lathe push rod and nitrogen spring moves to the end and after making the mould closure, completes the drawing and moulding to product.
