Description
Technical field
The present invention relates to auto-parts manufacture technical field of mold, and in particular to it is a kind of for vehicle bracket it is secondary into
Pattern has.
Background technology
Punch process is the blanks such as sheet material, tubing is produced plastic deformation or is separated using the pressure of forcing press.In automobile
In the processing of parts, many processing for carrying out various structures as raw material using steel plates, and for more complicated equal of structure
Realized by the way of diel is by cold punching.Typically entered for the especially complex structure of structure by the way of being repeatedly molded
OK, to improve the reasonable employment of forcing press, shaping structures are also allowed for.Vehicle bracket has complicated cross sectional shape and overall structure
Make, it is impossible to use single mould straight forming, on the one hand easily cause the damage of forcing press or mould, on the other hand can not protect
Demonstrate,prove one-time formed product be it is qualified, it is general using the shaping of two molds, the first procedure make the cross sectional shape of bracket into
Type, carries out overall structure shaping on post forming mould, can guarantee that the cross sectional shape of shaping for the first time and will not produce larger change
Shape.Existing mould needs integral demounting to be repaired and safeguarded, causes work by the way of global formation after there is damage
Work amount is big, and cost is high, for diel in itself, and damage is easily produced in use is all contact depressed position, and
And having relation with angle, position, stress is also unbalanced, causes situation about damaging also to differ, if multiple modules can be resolved into
The parts for having damage just only can be changed or repaired by assembling mode, allow production is sustainable to carry out.
The content of the invention
For the deficiency in the presence of prior art, the invention provides a kind of secondary forming die for vehicle bracket
Tool, solves the problems such as existing mold is not easy to maintenance and safeguarded, cost is high, shaped article uniformity is not high.
To achieve the above object, present invention employs following technical scheme：A kind of post forming for vehicle bracket
Mould, including upper mould and the lower mould that is engaged with upper mould, the lower mould include being connected with cavity plate installation on die shoe, the die shoe
Seat, is detachably provided with lower molding side component and lower die-cushion block assembly in the cavity plate mounting seat, the lower molding side component with
Lower die-cushion block assembly constitutes the cavity plate forming cavity that section is concave structure；The upper mould is included on upper bolster, the upper bolster
Be connected with the punch-pin mounting seat of " V " type structure, the punch-pin mounting seat and punch assembly detachably be installed, the punch assembly with
Cavity plate forming cavity is engaged；The Guiding machine acted on for upper mould mobile guide is additionally provided between the cavity plate mounting seat and upper bolster
Structure；The push rod for being provided with and being used for being molded the bracket demoulding is slided in the middle part of the die shoe.
In use, upper mould and lower mould are arranged on forcing press, then first stamping forming prefabricated bracket is put into down
Positioned above cavity plate forming cavity on mould, drive upper mould to move down by control pressure machine, be molded in punch assembly and spill
Under the mating reaction of die cavity so that prefabricated bracket overall structure is pressed into V-arrangement, and its cross sectional shape does not change, and wall thickness is equal
It is even.After post forming is finished, the push rod on die shoe ejects the bracket after shaping, and replaceable prefabricated bracket carries out next production
The punching press of product.
Compared to prior art, the present invention has the advantages that：
1st, overall punch assembly, lower molding side component and the lower mould for using demountable structure, particularly differing stress
Pad component etc. splits into parts combination, in use, can be quickly to producing damage, needing zero of maintenance
Part individually replace or safeguard, without being dismantled, being repaired to whole mould, installed, greatly reduce maintenance, repair into
This, improves the time of production equipment continuous production, improves the operating efficiency of maintenance workers；
2nd, cavity plate mounting seat uses intermediate pads, left installing plate and right installing plate combination, using separately machined, makes
Obtain processed complex simplifying, manufacturing cost reduction；
3rd, guide pad and guide rod are used cooperatively, and accurately the mobile of upper mould can be oriented to so that stamping products one
Cause property is high, and shaping can be directly entered subsequent manufacturing procedure, improve production efficiency.
