Fig. 3 is the action diagram of analysing and observe of Fig. 1 structure user mode.

See also Figure 1 and Figure 2, be expressed as the solid and the cutaway view of the utility model one preferred embodiment, it includes substantially: go up punch shank plate 10 in the module, two location-plates 20, push pedal 21, upper padding plate 30, train wheel bridge 50, in re-pack 60, caster 71 and down module stripper plate 80, lower plate 82, lower bolster 83, mould 90 and several joint bolt 2, jumper bar 1, link backstay 3, push rod 6, write off 5, punching mechanism A; In this structure,

The punch shank plate 10 of last module is provided with a convex connecting support 11, and is provided with connect apertures 8, the through hole 9 of perforation; Also be provided with on the location-plate 20 and can press from both sides fixed one push pedal 21 with screw fixed hole 4 between connect apertures 8, through hole 9, two location-plates 20 just; Upper padding plate 30 is provided with connect apertures 8, through hole 9 and writes off slide opening 70, main slide opening 7; Train wheel bridge 50 is same as upper padding plate 30 and is provided with similar hole, and heart place sets up a main slide opening 7 that connects therein; In re-pack and 60 be provided with and slidably write off 5; Caster 71 is provided with nib 72 and screw threads for fastening hole 4;

The stripper plate 80 of following module also is provided with nib 72, be equiped with model body 81 in it, the model body is then assembled and is fixed on the lower plate 82, and 80 of stripper plates cooperate spring 91 assemblings to be arranged on the lower plate 82, one lower bolster 83 is set under the lower plate 82 again, and overall package is fixed on the mould 90;

Preface is with punch shank plate 10 successively, location-plate 20, push pedal 21, upper padding plate 30, train wheel bridge 50, in re-pack 60, caster 71 is superimposed together, re-pack wherein and 60 be arranged in the nib 72 of caster 71, be arranged in train wheel bridge 50 and write off 5, in the abatement slide opening 70 of upper padding plate 30, just pushed up by push pedal 21 and ended restriction, push rod 6 is arranged in the main slide opening 7 of train wheel bridge 50 and upper padding plate 30, just pushed up and ended restriction by push pedal 21, joint bolt 2 then is located in each connect apertures 8 of each plate body, and be screwed together in the screw fixed hole 4 of caster 71, so that each plate body is combined into one, link 3 of backstays in addition and be arranged in punch shank plate 10, location-plate 20, upper padding plate 30, in the through hole 9 of train wheel bridge 50 and caster 71, make it have the not effect of loosening error of strengthening each plate body; One end of jumper bar 1 is assembled respectively on the connecting support 11 of the two ends of being fixed in push pedal 21 and punch shank plate 10, and the other end then is connected on the punching mechanism A; According to above-mentioned composition, and can quick and precisely form the last module of a punch die.

After above-mentioned structure of the present utility model was formed, action of the present utility model, effect then further specified as follows:

Now see also shown in Figure 3ly, after punching mechanism A action, clamp down on fifty-fifty in punch shank plate 10, the push pedal 21 by jumper bar 1; Subsequently, 10 of punch shank plates with pressure act on successively location-plate 20, upper padding plate 30, train wheel bridge 50, in re-pack 60, on the caster 71 push pedal 21 then pressure is acted on successively upper padding plate 30, train wheel bridge 50, in re-pack on 60, thereby re-pack 60 in making, writing off 5 can be according to the mating reaction of nib 70,72, caster 71, model body 81, punching out processing plate 41 according to interiorly re-pack 60, model body 81 shapes form finished product; And in the punching out action, stripper plate 80 cooperates spring 91 to move downwards, and after punching out was finished, last module broke away from punching press, and the elastic force of spring 91 can impel stripper plate 80 resiliences, reaches the purpose of automatic material separator; Can find out by above-mentioned explanation and diagram, location-plate 20 of the present utility model is designed to separate type, push pedal 21 then is designed to longer body, so, as when desiring punching out larger area processing plate, as long as change caster, in re-pack 60, can reach by long push pedal 21 and the jumper bar 1 that is evenly distributed setting and apply even stamping press and the work done of processing plate, perhaps, when tangible excessive the and push pedal 21 that is not suitable for of the size of processing plate, location-plate 20, also as long as push pedal 21, location-plate 20 are changed; So, the utlity model has following advantage feature as can be known by above-mentioned explanation:

1. the start punching press of stamping press is the multi-point average configuration work done that distributes, and can obtain average, balanced acting surface, and make the punching press work done steady, and precision also thereby improve.

2. be removable because of location-plate 20, push pedal 21, and application of force balance (application of force intensity can be adjusted by punching mechanism A) is constant, so replaceable caster 71, in re-pack 60 and make the utility model reach a mould can to do the utilization of various punching out processing plate, thereby reduce establishing of mould Standby cost.

Because of replaceable caster, in re-pack, location-plate, push pedal, and so that make processing fast.

4. location-plate, push pedal are straight shape batten, and it is a separate type, so easily manufactured, quick, simple and easy.

Comprehensively above-mentioned, the utility model can make the punching press compound die present a mould really and realize multi-mode function conversion use, make that die cost reduces, process velocity is fast, molding speed reaches simple and easy soon, and because of stamping press is designed to multi-point average distribution configuration, so the stamping press work done is steady, thereby improve the precision of machining object, have practicality and promote effect.
