Abstract
The invention relates to a novel reshaping die for an annular thin-wall part, which has a simple structure and favorable reshaping effect. The invention adopts the technical scheme that the reshaping die comprises an upper die plate and a lower die base, wherein the upper die plate and the lower die base are guided by a guiding mechanism to close the die; a female die structure is arranged on the upper die plate; a lower die plate is arranged on the lower die base; and a male die is arranged on the lower die plate. The reshaping die is characterized in that the female die structure comprises a female die outer frame; a female die insert is arranged in the female die outer frame and is made of polyurethane; and the male die is a rigid male die.
Description
Technical field
The present invention relates to the Stamping Die Technology field, be specially a kind of shaping mould of novel annular thin wall part.
Background technology
A kind of annular thin wall part that is used for automobile exhaust pipe, it is by excision bottom surface aftershaping behind the plain film material extending, because it is very thin for thin and thick, easily cylindrical loses circle and causes its excircle configuration degree not reach designing requirement behind the excision bottom surface, so need carry out shaping processing to it.Its punch of general shaping mould and die are rigid body, when this kind annular thin wall part is carried out the punching press shaping, and owing to its punch can not be fitted well with part, fragile part when punch and die carry out the punching press shaping to part, shaping effect is poor.
Summary of the invention
At the problems referred to above, the invention provides the shaping mould of novel annular thin wall part, it is simple in structure, and shaping effect is good.
Its technical scheme is such, it wraps template and die shoe, between described cope match-plate pattern and the die shoe by guiding mechanism guiding matched moulds, the die structure is installed on the described cope match-plate pattern, on the described die shoe lower bolster is installed, on the described lower bolster punch is installed, it is characterized in that: described die structure comprises the die housing, in the described die housing die plate insert is installed, described die plate insert is made by polyurethane, and described punch is the rigidity punch.
The shaping mould of novel annular thin wall part of the present invention, die plate insert in its die structure is made by polyurethane, because die plate insert is a soft material, it can be fitted well with the part wall when part is carried out the punching press shaping, thereby reaches fruit of shaping ideally.
Description of drawings
Fig. 1 is the shaping mould structural representation of novel annular thin wall part of the present invention.
The specific embodiment
See Fig. 1, it wraps template 1 and die shoe 2 the present invention, pass through guiding mechanism 3 guiding matched moulds between cope match-plate pattern 1 and the die shoe 2, the die structure is installed on the cope match-plate pattern 1, lower bolster 4 is installed on the die shoe 2, punch 5 is installed on the lower bolster 4, the die structure comprises die housing 6, die plate insert 7 is installed in the die housing 6, and die plate insert 7 is made by polyurethane, and punch 5 is the rigidity punch.
Claims (1)
