The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in Fig. 3,4, the present invention mainly is comprised of the patrix 1 of positioned opposite up and down and up stripper 2 and counterdie 3 and lower stripper 4, described patrix 1 comprises that one is installed in the upper bolster 11 on the equipment upper moving beam, the bottom of this upper bolster 11 is equipped with shaping blades 12 and the shaping blade 13 of adjacent layout, described patrix 1 supporting being inserted in the up stripper 2 of deciding on the equipment of being fixedly mounted on the beam; Described counterdie 3 comprises that one is installed in the die shoe 31 on the equipment lower movable beam, the top of this die shoe 31 also is equipped with shaping blades 32 and the shaping blade 33 of adjacent layout, described counterdie 3 supporting being inserted in the lower stripper 4 of deciding under the equipment of being fixedly mounted on the beam.
The top of the bottom of described upper bolster 11 and die shoe 31 is fixed with respectively end surface press plate 5 and side pressing plate 6, and by described end surface press plate 5 shaping blades and shaping blade lateral compression are formed the close contact of each section blade, by described side pressing plate 6 shaping blades and shaping blade are fastened on corresponding upper bolster 11 and the die shoe 31.
Described upper bolster 11 and die shoe 31 drive respectively the shaping blade that is fixed on upper bolster and the die shoe and shaping blade and pass the knife-edge passage of offering on the separately up stripper 2 and lower stripper 3, and the shape of the shape of described knife-edge passage and correspondingly configured blade and shaping blade is consistent, and is formed with each other a matched in clearance.
The isometry block 7 of the uniformity of short transverse, while capable of regulating product height tolerance when being respectively arranged with a plurality of assurance moulds installation on the upper surface of described upper bolster 11 and die shoe 31 lower surfaces.
Embodiment:
The present invention mainly is comprised of patrix, up stripper, lower stripper, counterdie, specifically sees shown in Fig. 3,4, among the figure:
Isometry block 7: guarantee the uniformity of short transverse when mould is installed, in debug process, can by adjusting indivedual isometry blocks, adjust the product height tolerance simultaneously;
Upper bolster and die shoe: shaping blades and integer blade mounting base; On the moving beam of the equipment that is installed in;
End surface press plate: the 1. benchmark installed of blade; 2. the lateral compression blade makes each section blade close contact;
Side pressing plate: tightly be fixed on shaping blades and integer blade on the die holder;
Shaping blades: finish the punch forming of fin;
The integer blade: the fin that punching out is finished carries out the profile repoussage, such as pitch, perpendicularity etc.
Up stripper and lower stripper: the equipment of being installed in is decided on the beam.1. when guaranteeing the demoulding, blade is deviate from from material fully, and the rubbish such as noresidue aluminium bits, aluminium foam in the blade; 2. in the punching out process, stripper plate can play effect 3. blades of guiding owing to can produce flexural deformation in punching out, and stripper plate can withstand on the side of cutter, can play backer's effect, effectively protects blade.
Tooling blade of the present invention adopts the mould preparation design: the blade of traditional design is divided into clamping part (handle of a knife) and moulding section (cutter head), and wherein clamping partly is width 3.0mm, thickness 6.0mm; Moulding section is that width 3.0mm, thickness are the thin slice of 0.9 ~ 1.8mm, and integral rigidity is poor, and is easily cracked; The set of blades dress is the wide punch die of 300mm the most at last.
Shown in Fig. 5,6, mould preparation of the present invention design takes full advantage of existing advanced Computerized Numerical Control processing technology, is the nominal thickness of mould preparation blade with insert design, is 1.5～1.8 times of conventional one-piece blade; The length direction conventional blades is 3mm, and novel blade is 96mm, and it is whole changing scattered.During assembling, conventional blades needs more than 100 sheets, and novel blade only needs 3 ~ 4, greatly reduces assembling and debugging difficulty.
The present invention has structurally adopted double insert design: traditional design only has row's blade to finish moulding; The present invention then has two row's blades, and according to forming process, first row is the moulding mould preparation, finishes punch forming; Second row is the shaping mould preparation, and profile of tooth is carried out the two times punch shaping; By secondary reshaping, the face shaping of fin is better, and to make the time of staying of mould in product be original 2 times, has greatly prolonged its " pressurize " time, increases its plastic deformation, has greatly reduced the bounce-back of fin, is conducive to the compression of fin pitch.
Stripper plate of the present invention adopts stationary structure: in the traditional design, counterbore is set on the die holder, is bolted stripper plate, install Compress Spring between die holder and stripper plate additional and finish and take off material, the two does not have precise positioning and relatively-stationary relation.
Die holder of the present invention and stripper plate are fastened on respectively the moving beam of equipment and decide on the beam, and in the punching out process, stripper plate can play the effect of guiding; Blade is owing to can produce flexural deformation in punching out simultaneously, and stripper plate can withstand on the side of cutter, can play backer's effect, effectively protects blade.
Blade of the present invention has adopted contoured design by the stripper plate passage: in the traditional design, blade is long shape hole by the passage on the stripper plate, only plays the effect of taking off material.In new design, this passage has adopted contoured design, and namely the shape of the shape of passage and blade is consistent; select matched in clearance; make blade in punching press, knockout course, be subject to " next to the skin " protection, and can in time clear up a small amount of aluminium bits that produce in the punching out process, protection mould.
