Abstract
The utility model discloses a kind of automobile back rest drawing thickening device, include punch, die, concave-convex mold, on described punch, be provided with concave-convex mold, the both sides of punch are provided with die, below described concave-convex mold, be provided with blank holder, in the middle of described blank holder and concave-convex mold, be provided with stock, the upside of described blank holder is provided with pressure ring; In reverse drawing, stock sidewall is applied to axial thrust, carry out the object of powerful drawing to reach drawing and to thicken, many to solve automobile back rest setup for drawing parts operational sequence, in conventional oppositely drawing sequence, can not in a work cloth, drawing obtain the part needing, and supply to realize the problem that inwall cylinder thickens at reverse drawing sequence.
Description
Technical field
The utility model relates to mould applications, relates in particular to a kind of automobile back rest drawing thickening device.
Background technology
Drawing process is exactly in fact the process of the flange portion automobile back rest of blank being transferred to gradually to barrel, current setup for drawing parts is for high surface area and the larger part of Wall-Thickness Difference, its operational sequence is many, inefficiency, input cost is high, and can not reach the object thickening in carrying out drawing, therefore, solve automobile back rest setup for drawing parts operational sequence many, in conventional oppositely drawing sequence, can not in a work cloth, drawing obtain the part needing, and it is particularly important in reverse drawing sequence, can not to realize the problem that inwall thickens.
Utility model content
The purpose of this utility model is to provide a kind of automobile back rest drawing thickening device, in reverse drawing, stock sidewall is applied to axial thrust, carry out the object of powerful drawing to reach drawing and to thicken, many to solve automobile back rest drawing thickening device operational sequence, in conventional oppositely drawing sequence, can not in a work cloth, drawing obtain the part needing, and supply to realize the problem that inwall thickens at reverse drawing sequence.
In order to address the above problem, the utility model provides a kind of automobile back rest drawing thickening device, include punch, die, concave-convex mold, on described punch, be provided with concave-convex mold, the both sides of punch are provided with die, below described concave-convex mold, be provided with blank holder, in the middle of described blank holder and concave-convex mold, be provided with stock, the upside of described blank holder is provided with pressure ring.
Further improve and be: described blank holder and pressure ring adopt arc blank holder and arc pressure ring.
Further improve and be: the spacing of described punch and die is set to 2.2mm, ensure that the overall performance of automobile back rest drawing can not decline.
Further improve and be: when device forward drawing, drawing die is fixed, oppositely concave-convex mold is fixed when drawing, and when pressure ring, punch are shaped, respectively downwards and move upward, die floats, passive movement under the effect of pressure ring.
The drawing step of described device is divided into forward drawing and reverse drawing.The pressure-pad-force of described forward drawing blank holder is set to 50kN, and the speed of punch is set to 5000mms
-1, after finishing control, the spacing of punch and die is 2.2mm.When described reverse drawing, the pressure-pad-force of blank holder is 300kN, and the pressure-pad-force of die is 50kN, described in the speed of damaging by pressure be set to 2068.7 mms
-1, then with 50 mms
-1speed increase.
The beneficial effects of the utility model are: drawing process is divided into forward drawing and reverse drawing, forward drawing is first drawing, again oppositely when drawing, lateral wall is applied to downward thrust, to promote the inside sidewall of outside metal flow, according to volume equal principle, when the speed of damaging by pressure reaches certain when critical, flow into inner metal by pressure ring effect and equal the required metal of punch direction drawing, now can ensure metal to carry out reverse drawing and can attenuate, when pressure ring speed is greater than this when critical, just can play the effect thickening, adopt arc blank holder and pressure ring can ensure the automobile back rest again outer wall flow to inwall, make reverse drawing better effects if.The utility model is simple in structure, and operational sequence is simple, and input cost is low, in automobile back rest drawing process, has played the effect thickening.

Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As shown in Figure 1, 2, 3, the utility model provides a kind of automobile back rest drawing thickening device, include punch 1, die 2, concave-convex mold 3, on described punch 1, be provided with concave-convex mold 3, the both sides of punch 1 are provided with die 2, below described concave-convex mold 3, be provided with blank holder 4, described blank holder 4 is provided with stock 5 with concave-convex mold 3 is middle, and the upside of described blank holder 4 is provided with pressure ring 6.Described blank holder 4 and pressure ring 6 adopt arc blank holder and arc pressure ring.Described punch 1 is set to 2.2mm with the spacing of die 2, ensures that the overall performance of automobile back rest drawing can not decline.When device forward drawing, drawing die 1 is fixed, and oppositely concave-convex mold 3 is fixed when drawing, and when pressure ring 6, punch 1 are shaped, respectively downwards and move upward, die 2 floats, passive movement under the effect of pressure ring 6.Pressure ring 6 can effectively promote the automobile back rest to have outer wall to flow to inwall, and produces and thicken phenomenon in inwall bottom, and pressure ring 6 speed are higher, bottom to thicken phenomenon more obvious.
