The pre-forming die is characterized in that a lower die structure further comprises a material pressing plate which is installed on a lower fixing plate, a lower forming die is installed in the material pressing plate and connected with the lower fixing plate, an ejector rod is installed in the lower fixing plate, the ejector rod vertically penetrates through the lower fixing plate, a lower bolster and a lower die plate, a guide rod of a nitrogen cylinder is connected to the lower portion of the ejector rod, and the nitrogen cylinder is installed on an installation plate.
Description
Technical field
The utility model relates to the parts punch process field of automobile engine exhaust system, is specially a kind of piece pre-forming die of automobile engine exhaust system manifold.
Background technology
A kind of automobile engine exhaust system manifold, it is connected and is expected to cut after one stretch forming by upper half shell and lower half shell, amalgamation welding processing again forms, because connecting, its upper half shell and lower half shell expect that the forming surface height of one stretch forming is higher and forming surface is complicated, disposable direct punching stretch is shaped and easily causes housing cracking, therefore need first workpiece to be carried out to preform, Workpiece structure schematic diagram after preform is shown in Fig. 1 and Fig. 2, because preformed material extending height is high and extension area is large, in stamping process, can exist due to the component shaping problem not in place that Work-sheet pressing power deficiency is caused.
Summary of the invention
For the problems referred to above, the utility model provides a kind of piece pre-forming die of automobile engine exhaust system manifold, and it solves the problem of existing shaping dies to Work-sheet pressing deficiency, guarantees that a punching press of workpiece can put in place by preform,
Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises cope match-plate pattern and shaping patrix, shaping patrix is installed under described cope match-plate pattern, described lower die structure comprises lower bolster, lower bolster, bottom plate and forming lower die, described bottom plate is installed on described lower bolster by described lower bolster, described forming lower die is installed on described bottom plate, described shaping patrix coordinates with forming lower die profile, described lower bolster is installed on installing plate by counterdie pin, described upper die structure and lower die structure are by independent sliding guide piece guiding matched moulds, it is characterized in that: described lower die structure also comprises holding pad, described holding pad is installed on described bottom plate, described forming lower die is installed in described holding pad and is connected with described bottom plate, in described bottom plate, push rod is installed, described push rod vertically runs through described bottom plate and lower bolster and lower bolster, described push rod bottom connects the guide rod of nitrogen cylinder, described nitrogen cylinder is installed on described installing plate.
It is further characterized in that:
In described shaping patrix, ejector pin is installed, described ejector pin passes through vertically wears described shaping patrix and described ejector pin upper end connection Rectangular Spring, and described Rectangular Spring is installed in cope match-plate pattern;
Longitudinal both sides of described holding pad are separately installed with guide pad, and longitudinal both sides of described shaping patrix have direction recess, when described upper die structure and lower die structure matched moulds described in guide pad embed in described direction recess;
On described holding pad, be provided with workpiece nail;
In described holding pad, be also provided with limit for height piece, described limit for height piece is installed in described holding pad by bolt, and the end face of described limit for height piece is higher than described holding pad plane.
The utility model piece pre-forming die, it upwards holds out against push rod by nitrogen cylinder and guarantees that holding pad is to the reliable thrust uniformly of workpiece, thereby guarantees that component shaping puts in place; And ejector pin in shaping patrix connects Rectangular Spring, can further guarantee the reliable of workpiece to compress uniformly; And the guide pad of the longitudinal both sides of holding pad coordinates with the guiding die of shaping patrix, the reliable matched moulds of can guarantee to be shaped patrix and forming lower die, patrix or forming lower die sidesway and press the problem of inclined to one side workpiece prevent from being shaped; Workpiece nail is set on holding pad, can plays the reliable spacing effect of workpiece; Limit for height piece is set in holding pad, and the end face of limit for height piece, higher than holding pad plane, can effectively guarantee to meet thickness requirement after workpiece preform.
