Description

Stringer upper plate stretch form die
Technical field
The utility model relates to arrive automobile longitudinal girder production technical field, specifically, being a kind of stringer upper plate stretch forming Mould.
Background technique
Stringer plays a crucial role in automobile chassis product piece, and when work needs to carry biggish weight, And components connected to it also compare it is more, so the processing quality of stringer for entire automobile working performance with biggish It influences.
When drawing die processes stringer, the existing left and right upper plate of stringer is opened respectively carries out stretch forming, due to plate material The limited width of material and length is longer, and the structure of stringer be "Ji" type structure, therefore die plate insert drive stringer blank When deforming, the middle part of stringer blank by external force, does not cause in process, is easy to appear back in the middle part of stringer blank The defects of bullet or torsional deformation, so that the processing quality of stringer is poor.In addition, independent die sinking there is also production efficiencys low, material Waste the defects of serious.
In conclusion the problems such as processing quality for how solving stringer is poor, production efficiency is low, it has also become art technology Personnel's technical problem urgently to be resolved.
Utility model content
In view of the deficiencies of the prior art, it the purpose of the utility model is to provide a kind of at low cost, high-efficient, and can be avoided There is the stringer upper plate stretch form die for springing back or distorting in forming process.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:
A kind of stringer upper plate stretch form die, including upper die holder and lower die holder, key are: being arranged on the lower die holder There is supporting piece bracket, is provided with multiple workpiece stop blocks on the supporting piece bracket, is set in the region that multiple workpiece stop blocks surround It is equipped with the punch insert being adapted with stringer upper plate workpiece, the two sides of the punch insert groove profile with left and right stringer upper plate respectively It is adapted, puncturing blade is provided in the middle part of the punch insert, under being provided between the punch insert and supporting piece bracket It is molded flange insert, the die plate insert matched with the punch insert is provided on the upper die holder, in the die plate insert Center offer with the puncturing blade be adapted notch, the side of the die plate insert be provided with upper mold blank holder edge Block.
This stretch form die can be to the left and right upper plate one stretch forming of stringer, to increase material when stretch forming The width of material effectively prevents the rebound of stringer upper plate or torsional deformation phenomenon in forming process;And mold closure, part at During shape, the medium position of plate is punctured by the puncturing blade of setting, consequently facilitating the flowing of part shapes, is avoided Middle part forming too deep the phenomenon that being easy cracking when stringer or so upper plate shapes simultaneously.
Further, cavity plate backing plate insert, the cavity plate backing plate edge are provided between the upper die holder and die plate insert The lower end of block is in contact with the upper mold blank holder insert.
Be arranged cavity plate backing plate insert avoid between die plate insert and upper die holder directly contacting, namely avoid workpiece at Upper die holder is downwardly applied to the damage caused by die plate insert when pressure when shape, to not only provide well to die plate insert Protection, and also avoid the influence caused by processing quality after die plate insert damage.
Further, the puncturing blade is made of block portion and knife edge part, and the block portion is used to adjust knife The height of blade portion, the knife edge part raise upward and can protrude into the notch.
During mold closure, part forming, local location of the machine among plate punctures plate to puncturing blade in due course Material is conducive to material flowing forming, part is avoided to crack;And block portion needing to puncturing blade according to production scene can be passed through The height of knife edge part is adjusted, the strong guarantee using effect of puncturing blade.
Further, the workpiece stop block includes the fixed mounting blocks on the supporting piece bracket, in the mounting blocks Inner end extend internally and limited block be installed.
Using the above structure, workpiece stop block is fixed on supporting piece bracket, to improve the connection of workpiece stop block The service life of this mold can be improved in intensity.
Further, the inside on the limited block top is equipped with smooth surface.By setting smooth surface convenient for workpiece Part and pickup are put, working efficiency is helped to improve.
Further, lifting lug is provided at the both ends of the upper die holder, lower die holder and supporting piece bracket.
The remarkable result of the utility model is: structure is simple, easy to operate, and forming quality is reliable, by by left-right longeron Upper plate is integrally formed, so that moulding material is widened, effectively prevents rebound or the twisted phenomena of stringer part, improves product matter Amount, while high production efficiency, also save raw material, reduce mold opening cost;And by setting puncturing blade, in due course machine in Local location punctures plate among plate, is conducive to material flowing forming, part is avoided to crack.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the schematic diagram after the utility model removal upper die holder and part insert.
Specific embodiment
Specific embodiment of the present utility model and working principle are described in further detail with reference to the accompanying drawing.
As shown in Figures 1 and 2, a kind of stringer upper plate stretch form die, including upper die holder 1 and lower die holder 2, the lower die holder It is provided with supporting piece bracket 3 on 2, multiple workpiece stop blocks 4 are provided on the supporting piece bracket 3, is surrounded in multiple workpiece stop blocks 4 Region in be provided with the punch insert 5 being adapted with stringer upper plate workpiece, the two sides of the punch insert 5 respectively with it is left and right vertical The groove profile of beam upper plate is adapted, and the middle part of the punch insert 5 is provided with puncturing blade 6, sliding at the center of the supporting piece bracket 3 It is dynamic to be provided with correcting sliding block 7, lower die blank holder insert 8 is provided between the punch insert 5 and supporting piece bracket 3, described It is provided with the die plate insert 9 matched with the punch insert 5 on upper die holder 1, is offered and institute at the center of the die plate insert 9 The adaptable notch 10 of puncturing blade 6 is stated, the side of the die plate insert 9 is provided with upper mold blank holder insert 11.On described Cavity plate backing plate insert 12, the lower end of the cavity plate backing plate insert 12 and the upper mold are provided between die holder 1 and die plate insert 9 Blank holder insert 11 is in contact.
