Description
Technical field
The utility model belongs to Automobile Cover Drawing Die technical field, more particularly to a kind of to have plate supporting device
Vehicle side-wall outer-plate drawing die.
Background technology
Vehicle side-wall outer-plate is one of important covering of automobile, with the change of automobile external moulding, outside vehicle side
The shape of plate changes therewith, and the wherein radius of corner of the crest line of automobile wheel arch position and the angle of adjacent surface diminishes, no
Manufacture difficulty is increase only, and is more easy to skid wire occur in wheel arch position.
In order to control the appearance of skid wire, technical staff frequently with method include adjustment pressing direction, using drawing
Prolong muscle adjustment or using modes such as adjusting process supplement shapes, wherein：
Adjustment pressing direction to the control effect of skid wire preferably, but due to pressing direction be it is unique, can only be to one
Bar skid wire is controlled, therefore when considering to be controlled skid wire, the cunning of control vehicle body main ridge is often considered first
Shifting line, and the not skid wire of wheel arch position.
The method of bead adjustment is by increasing the resistance between plate and drawing die, reaching control panel material influx
Purpose, although the method can play a part of to control skid wire, because bead changes the local shaping of plate
State, thus when increasing or reducing bead coefficient, plate occurs by drawing crack, fold or deforms insufficient problem, makes
There is larger limitation in the method that must control skid wire using bead adjustment.
Adjusting process supplement shape is to make it with drawing punch while contacting plate or comparing drawing punch by supplementing shape
Plate is contacted earlier, so as to control the inflow of plate, and then reaches the purpose of control skid wire, but due to the shape of technique supplement
Shape is limited so that control the effect of skid wire limited by the way of technique supplement.
It follows that it is above-mentioned three kinds control skid wire method all have some limitations, itself main reason is that on
