Description
Technical field
The utility model belongs to Stamping Die Technology field, particularly relates to a kind of without push rod structure drawing die.
Background technology
Diel is one of automobile production important step, and current body of a motor car stamping parts mainly passes through cold
The mode of punching press realizes, its forming process mainly includes the operations such as drawing, Xiu Chong, flange, shaping.Draw
Prolonging mould to be mainly made up of punch, die, blank holder three parts, in punching course, plate passes through upper mold
First compressing with blank holder, then jointly moving downward, during moving downward, punch is again by blank stretch forming.
The motion of drawing die blank holder relies primarily on lathe push rod and provides power, and it is straight that lathe push rod passes through die shoe
Connect and act on bottom blank holder, because push rod quantity and position are inconsistent needed for each stamping parts, therefore treat that certain rushes
Casting die produces after terminating, and drawing die need to be hung board, according to will readjust top by production mould push rod figure
Bar, then mould to be produced is winched to board complete die change, its production efficiency is low, and artificial arranges that push rod can not
100% is accurate, it is possible to causes the generation of push rod and die ontology collision accident.
As shown in Figure 1 to Figure 3, respectively the lower die structure of prior art drawing die, blank holder structure and on
Mode structure schematic diagram, traditional drawing die mainly includes that lower mold, flanging ensphere upper mold three parts, lower mold bag
Include lower mold base the 05th, punch insert the 02nd, hanger the 07th, jogger hole the 04th, guide plate the 03rd, breaker bolt 01 and pier
Dead block 06；The 013rd, blank holder includes dead block the 012nd, the tip-lever support of blank holder body the 011st, material supporting rack the 08th, pier
Hanger the 010th, location-plate 09；Upper mold includes die body the 016th, hanger the 015th, balance weight 014.Produce
During, push rod passes through lower mold push rod and acts on blank holder tip-lever support, and board moves through push rod and provides pressure
Flange power, it is achieved the purpose of drawing binder.
In prior art, when production line stamping parts produces switching, first drawing die is hung board, operation
Lathe sliding block goes upward to push rod and can take position, according to production mould push rod figure will taking out and increase corresponding
Push rod, after push rod is adjusted in place, will produce drawing die and be hoisted on board, and mould switching finishes.
The shortcoming of prior art is, manual operation load is relatively big, reduces production efficiency, and artificial replacing push rod is not
Energy 100% is accurate, it is possible to cause the generation of push rod and die ontology collision accident；Prior art needs
Production line near zone arranges exclusive region and frock deposits push rod, is unfavorable for field management, increases frock and becomes
This.
In order to overcome drawbacks described above, CN201310180875.X discloses a kind of Hub Castings part drawing mould, should
Technical scheme eliminates the use to push rod, but the mould of the mould structure of this technical scheme and prior art
Lamps structure has bigger difference, it is impossible to this technical scheme directly applies to the transformation of existing diel.
