Description
Technical field
The utility model belongs to mould applications, and in particular to a kind of bending die of machining support.
Background technology
Bending process is the needs according to part shape, and blank is curved certain angle, certain by mold and forcing press
The Sheet Metal Forming Technology method of shape workpiece.Bending die is the equipment for completing bending machining.
Holder is a kind of workpiece of support, and holder is integrally symmetrical and has the bending structure of 4 corners；Branch
Frame is close with the shape of top half of " convex " word in the section configuration of width direction, and the top surface of holder is provided through bolt company
Connect hole.Currently, holder is process by block " being bent after first punching ", " bending " therein processing is i.e. using bending die come complete
At.
Notification number is in the prior art：The patent of CN205324464U discloses a kind of " hat shape with swing block type cavity plate
Part bending die " is somebody's turn to do " the cap bending die for carrying swing block type cavity plate "（Referring to this specification attached drawing 1）Including upper male mould 1, lower die
Seat 2, mandril 3, spring mounting seat 4, spring 5, swing block type cavity plate 6 and backing plate 7, upper male mould 1 are located above upper die holder, lower die holder
2 middle parts are provided with vertical through-hole, are equipped with mandril 3 in through-hole, the upper male mould 1 can vertical and straight movement, and the upper male mould 1 has
Ladder boss is set on 2 top of the lower die holder there are two with the symmetrical swing block type cavity plate 6 of the axial centre of mandril 3, swing block type
The outer end of cavity plate 6 is hinged on axis, and the inner end of swing block type cavity plate 6 is provided with straight trough, when swing block type cavity plate 6 is located at initial position
The end of two cell walls of straight trough is in same level, and when blank forming, two straight troughs of swing block type cavity plate are opposite to form cavity,
Mandril 3 can jack up the inner end of swing block type cavity plate 6, and the size of cavity and the size of the ladder boss of upper male mould 1 match.
But above-mentioned " the cap bending die for carrying swing block type cavity plate " still has following shortcoming：
Because mandril 3 is acted in 5 elastic force of spring in before processing, above-mentioned " the cap bending die for carrying swing block type cavity plate "
It is lower to jack up swing block type cavity plate 6, by " top edge of two cell walls of every block of swing block type cavity plate 6 is in same level "
Structure, to be supported to Single Size Rectangular Blanks to be processed.But it is between above-mentioned top edge and Single Size Rectangular Blanks to be processed
The contact in " line and face ", it is difficult to Single Size Rectangular Blanks to be processed have stably and reliably been supported by the top edge.
So during bending machining, when 1 lower face of upper male mould is just in contact with Single Size Rectangular Blanks to be processed,
