Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 3,4, the present invention forms primarily of patrix 1 positioned opposite up and down and up stripper 2 and counterdie 4 and lower stripper 3, described patrix 1 comprises one and is arranged on upper bolster 11 on equipment upper moving beam, the bottom of this upper bolster 11 is provided with shaping blade and the shaping blade of adjacent layout, and described patrix 1 is supporting to be inserted in the up stripper 2 equipment of being fixedly mounted on determined on beam; Described counterdie 4 comprises one and is arranged on die shoe on equipment lower movable beam, and the top of this die shoe is also provided with shaping blade and the shaping blade of adjacent layout, described counterdie 4 is supporting be inserted in the equipment of being fixedly mounted under determine on beam lower stripper 3.
The bottom of described upper bolster 11 and the top of die shoe are fixed with end surface press plate 5 and side pressing plate 6 respectively, and by described end surface press plate 5, shaping blade and shaping blade lateral compression are formed the close contact of each section of blade, by described side pressing plate 6, shaping blade and shaping blade are fastened on corresponding upper bolster 11 and die shoe.
Described upper bolster 11 and die shoe drive respectively and are fixed on shaping blade on upper bolster and die shoe and shaping blade through the knife-edge passage that respective up stripper 2 and lower stripper 3 are offered, and the shape of described knife-edge passage is consistent with the form trait of correspondingly configured blade and shaping blade, is formed with a matched in clearance each other.
The upper surface of described upper bolster 11 and die shoe lower surface are respectively arranged with the isometry block 7 of the uniformity of short transverse when multiple guarantee mould is installed, simultaneously adjustable product height tolerance.
Embodiment:
The present invention, primarily of patrix, up stripper, lower stripper, counterdie composition, is specifically shown in shown in Fig. 3,4, in figure:
Isometry block 7: the uniformity of short transverse when ensureing that mould is installed, simultaneously in debug process by adjusting indivedual isometry block, adjustment product height tolerance;
Upper bolster and die shoe: shaping blade and shaping blade mounting base; The equipment of being arranged on moves on beam;
End surface press plate: the 1. benchmark of blade installation; 2. lateral compression blade makes each section of blade close contact;
Side pressing plate: shaping blade and shaping blade are tightly fixed on die holder;
Shaping blade: the punch forming completing fin;
Shaping blade: profile repoussage is carried out, as pitch, perpendicularity etc. to the fin that punching completes.
Up stripper and lower stripper: the equipment of being arranged on is determined on beam.1., when guaranteeing the demoulding, blade is deviate from completely from material, and the rubbish such as noresidue aluminium bits, aluminium foam in blade; 2., in punching process, stripper plate can play effect 3. blade of guiding owing to can produce flexural deformation in punching, and stripper plate can withstand on the side of cutter, can play the effect of backer, available protecting blade.
Tooling blade of the present invention adopts 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 part is width 3.0mm, thickness 6.0mm; Moulding section is width 3.0mm, thickness is the thin slice of 0.9 ~ 1.8mm, and integral rigidity is poor, easily cracked; Set of blades fills as the wide punch die of 300mm the most at last.
Shown in Fig. 5,6, mould preparation design of the present invention, making full use of existing advanced Computerized Numerical Control processing technology, is the nominal thickness of mould preparation blade by insert design, is 1.5 ~ 1.8 times of conventional one-piece blade; Length direction conventional blades is 3mm, and novel blade is 96mm, changes scattered for overall.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 structurally have employed double insert design: traditional design only has row's blade to complete shaping; The present invention then has two row's blades, and according to forming process, first row is shaping mould preparation, completes punch forming; Second row is shaping mould preparation, carries out two times punch shaping to profile of tooth; By secondary reshaping, the face shaping of fin is better, and makes the time of staying of mould in product be original 2 times, substantially prolongs its " pressurize " time, increases its plastic deformation, substantially reduce the bounce-back of fin, be conducive to the compression of fin pitch.
Stripper plate of the present invention adopts stationary structure: in traditional design, die holder arranges counterbore, be bolted stripper plate, and install Compress Spring between die holder and stripper plate additional and complete de-material, the two does not have precise positioning and relatively-stationary relation.
Die holder of the present invention and stripper plate are fastened on the dynamic beam of equipment respectively and determine on beam, and in punching process, stripper plate can play the effect of guiding; Blade owing to can produce flexural deformation in punching simultaneously, and stripper plate can withstand on the side of cutter, can play the effect of backer, available protecting blade.
Blade of the present invention have employed contoured design by stripper plate passage: in traditional design, and blade is long shape hole by the passage on stripper plate, only plays the effect of de-material.In new design, this passage have employed contoured design, namely the shape of passage and the form trait of blade consistent; select matched in clearance; make blade in punching press, knockout course, be subject to " next to the skin " protection, and a small amount of aluminium bits produced in punching process can be cleared up in time, protection mould.
