Block, pressure plare and sliding shoe, the template plate and support plate are integrally welded, the described adjusting block setting support plate with
Between pressure plare, sliding shoe is arranged on pressure plare, and pressure plare and adjusting block are fixed on the supporting plate by fastening bolt.
The coupling block and punch-pin is clamped by fastener.
The adjusting block is composed of different number different-thickness M type plate, changes tune by adjusting plate quantity
The width of locking nub realizes that grade sizes of opening adjust more.
The sliding shoe uses optical axis, the both ends processing step structure annulus at the top of pressure plare, at the top of pressure plare in
Portion is equipped with semi open model ring, and one end of sliding shoe penetrates pressure plare unilateral side annulus, and the other end of sliding shoe is filled in intermediate semi-open
In formula ring.
The two sides of the template upper plate and coupling block vertical welding, coupling block are equipped with several strengthening version fixed form upper plates
With coupling block.
Support plate is reinforced by welding stiffener plate on the outside of the support plate.
The beneficial effects of the present invention are: for identical jobs a variety of bending R angle circular arc and opening a grade size, it is only necessary to primary dress
Die holder up and down is pressed from both sides, by replacing upper die holder punch-pin, lower die holder adjusting block is adjusted and changes bending parameter, to realize that a mould is more
With lead-time, raising working efficiency reduce security risk repeatedly for reduction.The bender under the action of sliding shoe,
Workpiece appearance after bending is more preferable, and demoulding is light.

Specific embodiment
A kind of adjustable bending die as shown in fig. 1 to fig. 4, it is characterised in that: including upper die holder 1 and lower die holder 2,
The upper die holder 1 includes template upper plate 3, coupling block 4 and punch-pin 5, and the template upper plate 3 and coupling block 4 weld, described
Coupling block 4 and punch-pin 5 are flexibly connected by T-slot 6, the lower die holder 2 include template plate 7, support plate 8, adjusting block 9,
Pressure plare 10 and sliding shoe 11, the template plate 7 and support plate 8 are integrally welded, and the setting of adjusting block 9 is supporting
Between plate 8 and pressure plare 10, sliding shoe 11 is arranged on pressure plare 10, and pressure plare 10 and adjusting block 9 are solid by fastening bolt 12
It is scheduled in support plate 8.
The coupling block 4 is clamped with punch-pin 5 by fastener 13.
The adjusting block 9 is composed of different number different-thickness M type plate, changes tune by adjusting plate quantity
The width of locking nub 9 realizes that grade sizes of opening adjust more.
The sliding shoe 11 uses optical axis, the both ends processing step structure annulus 14 at 10 top of pressure plare, pressure plare 10
The middle part at top is equipped with semi open model ring 15, and one end of sliding shoe 11 penetrates pressure plare unilateral side annulus 14, sliding shoe 11 it is another
