Description

A kind of adjustable bending die

Technical field

The present invention relates to a kind of adjustable bending dies, belong to coal mine machinery technical field.

Background technique

The components of existing coal mine machinery mining equipment need bending part more, and identical jobs need the angle a variety of bending R Circular arc and open a grade size.In production process, requirement can be met using simple bending die bending, but need to replace with repeatedly, Lower mould.The Bending Mould size as needed for mining equipment workpiece is larger, Reusability driving lifting replacement mold, production Inefficiency, there are security risks.Traditional lower mould uses welded-steel plate construction, can make bending part surface in bending process Bite mark is generated, and demoulds difficulty.

Summary of the invention

Place in order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of adjustable bending die, by more Change punch-pin, a grade adjusting block is opened in adjustment, to meet the angle a variety of bending R and the needs of grade size is opened in a variety of bendings.On lower mould Sliding shoe is set, reduces mold to friction of workpiece power, improves demoulding efficiency, ensure safe operation.

The present invention is achieved through the following technical solutions: a kind of adjustable bending die, it is characterised in that: including upper Die holder and lower die holder, the upper die holder include template upper plate, coupling block and punch-pin, and the template upper plate and coupling block weld It connects, the coupling block is flexibly connected with punch-pin by T-slot, and the lower die holder includes template plate, support plate, adjusting 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 End plug enters in intermediate semi open model ring 15.

The two sides of the template upper plate 3 and 4 vertical welding of coupling block, coupling block 4 are equipped with several 16 stents of strengthening version Plate upper plate 3 and coupling block 4.

Support plate 8 is reinforced by welding stiffener plate 17 on the outside of the support plate 8.

For identical jobs a variety of bending R angle circular arc and a grade size is opened, present invention only requires clamped one time upper die holders 1 under Die holder 2, by replacing the punch-pin 5 of upper die holder 1, the adjusting block 9 for adjusting lower die holder 2 changes bending parameter, realizes that a mould is more With lead-time, raising working efficiency reduce security risk repeatedly for reduction.Effect of the bender in sliding shoe 11 Under, the workpiece appearance after bending is more preferable, and demoulding is light.In use, for identical jobs a variety of bending R angle circular arc and opening shelves The suitable punch-pin 5 of size selection, punch-pin 5 are flexibly connected by T-slot 6 with coupling block 4, are then clamped by fastener 13, are adjusted Locking nub 9 is composed of different number different-thickness M type plate, and template plate 7 and support plate 8 are integrally welded, passes through release Fastening bolt 12, selects grafting certain amount thickness M type plate to form adjusting block 9, and realization adjusts lower die in appropriate range Seat opens a grade size, realizes that grade sizes of opening adjust more, plate is directly placed between support plate 8 and pressure plare 10, and by tight Fastening bolt 12 clamps, the convenient fast assembling-disassembling on press machine of the structure, it is ensured that dismounting mold Hoisting Security.Sliding shoe 11 will press Power machine lower die holder 2 becomes sliding friction as rolling friction, and reducing the mold side in pressing process influences the surface bite mark of workpiece, together When reduce knockout press, ensure demoulding safety.
