Below in conjunction with accompanying drawing, the utility model is further described:
Embodiment 1
A kind of reflector component die, comprises upper bolster 1, nitrogen spring cushion block 2, nitrogen spring upper mounting plate 3, moulding sleeve pipe 4, guide pillar 5, forming terrace die 6, upper jacking block 7, upper blank holder piece 8, lower blank holder piece 9, die shoe 10, nitrogen spring lower installation board 11, counterdie cutting edge piece 12, female die for forming 13, lower module 14, lower jacking block 15, packing ring 16, sleeve pipe 17, limited block 18, 4 are played davit 19 and nitrogen spring device, upper bolster 1 connects nitrogen spring upper mounting plate 3, nitrogen spring cushion block 2 connects upper bolster 1, moulding sleeve pipe 4 joint forming punch 6, guide pillar 5 joint forming punch 6, forming terrace die 6 connects upper jacking block 7, upper jacking block 7 connects upper blank holder piece 8, upper blank holder piece 8 connects lower blank holder piece 9, lower blank holder piece 9 connects counterdie cutting edge piece 12, die shoe 10 connects nitrogen spring lower installation board 11, female die for forming 13 connects lower module 14, lower jacking block 15 connects die shoe 10, packing ring 16 joint sleeves 17, sleeve pipe 17 connects limited block 18, mould both sides respectively have 2 to play davit 19 up and down, nitrogen spring device is in mould inner ring and outer ring, described counterdie cutting edge piece 12 is a large-scale occluded ellipse shape, adopt edge to spell after structure is divided into the trimming cutting edge of counterdie 10 little pieces and processes respectively, on the female die for forming of counterdie, splice, described upper bolster 1, die shoe 10, forming terrace die 6, female die for forming 13 adopts the lost foam casting process taking Bao Lilong as material to produce, and described nitrogen spring device comprises hose coupling 21 and nitrogen spring 20, is filled with nitrogen to nitrogen spring 20 by hose coupling 21.
Embodiment 2
The course of work: mould is joined pressure regulation system and produced on ordinary press.Before mould matched moulds, nitrogen spring system is started working, and blank holder piece and lower blank holder piece are compressed plate, and forming terrace die and female die for forming are shaped to part profile.Under the effect of nitrogen spring system, the patrix of mould continues to move downward, and lower jacking block moves downward under the effect of patrix, and forming terrace die is motionless, carries out trimming and the punching of part.After the shaping of part, trimming, punching complete, patrix moves upward, and under the effect of nitrogen spring system, forming terrace die and female die for forming are not separated, and after waste material unloads, upper and lower mould separates completely, completes the production process of a part.
Part forming need to carry out binder and discharging to plate, and this just has higher requirement to press.Ordinary press or hydraulic press generally only have a slide block, can not meet the needs of part pressure-plate-force and anti-top power, also greatly reduce the utilization rate of common press.Traditional punch die uses spring and rubber to provide binder and kicking force as flexible member, and its shortcoming is that elastic force is little, and the elastic force pressure of spring and rubber all increases with compression travel.The power one stroke curve of common spring is the linear relationship of larger slope substantially, the elastic force pressure one stroke curve of rubber-like element is nonlinear change, elastic force is along with the increase of stroke sharply increases, want accurate Calculation caoutchouc elasticity characteristic very difficult, the problem that will solve in addition rubber lateral expansion when compressed must reserve this part space in Design of Dies.So in part binder and discharging structure design, use nitrogen spring to carry out binder and the discharging of part, can address the above problem preferably.Nitrogen spring utilizes nitrogen as working media (nitrogen pressure is generally below 15MPa), the course of work of nitrogen spring can be similar to thinks that isothermal nitrogen expands and compression process, can select the different initialization pressure of nitrogen spring to obtain different elastic force pressures, also can select different nitrogen spring quality or volume, to obtain the elastic force pressure characteristic curve of Different Slope.Nitrogen spring can be used as individual components and is arranged in mould and uses, and also can be designed to a kind of nitrogen spring system becomes the part participation work of mould.Nitrogen spring can be realized easily the constant and time delay of elastic force pressure pressurization in system.In mould, used independently built-in nitrogen spring, also used the part of adjustable nitrogen spring system as mould simultaneously, the advantage that has fully utilized nitrogen spring is carried out binder and the discharging of part.Can control nitrogen spring system by control valve, make the parts such as its forming terrace die that promotes mould, female die for forming, upper and lower blank holder, jacking block, complete the technological requirement of part forming, punching, trimming.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
