Abstract
The utility model discloses a kind of heading die adopting compressed air type to eject, comprise upper bolster and die shoe, patrix is fixedly connected with below upper bolster, side plate is fixedly connected with above die shoe, intermediate pads is fixedly connected with above side plate, the counterdie that above intermediate pads, fixed installation is corresponding with patrix, the upper cavity holding workpiece is provided with in the middle of patrix, the lower chamber holding workpiece is provided with in the middle of counterdie, be inlaid with counterdie cushion block bottom lower chamber, and formed between counterdie cushion block and counterdie and be tightly connected; Counterdie cushion block upper surface is equipped with sawdust layer.Heading die of the present utility model, utilizes blast principle, realizes ejecting of workpiece, and simple, quick, production efficiency is high.
Description
Technical field
The utility model belongs to forge die technical field, is specifically related to a kind of heading die adopting compressed air type to eject.
Background technology
Heading die belongs to the one in forge die, is to utilize patrix and counterdie matched moulds to pressurize, and makes the forging mold that the height of blank workpiece reduces, area of section increases.Usually after matched moulds, blank workpiece, due to after overstriking, is embedded in counterdie, by independent ejecting mechanism, blank workpiece must could be ejected, then could take out workpiece.Existing ejecting mechanism comprises ejector beam usually, and drives the driving mechanism of ejector beam.Ejecting mechanism needs independent installation and debugging, brings many inconvenience to mold use, and for the heavy forging that quality is larger, eject also very difficult, production efficiency is low.
Utility model content
The purpose of this utility model is: for Problems existing in existing heading die, provides a kind of heading die adopting compressed air type to eject, and ejection part separation structure is simple, and ejecting force is large, heavy forging larger for quality can be ejected smoothly.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of heading die adopting compressed air type to eject, comprise upper bolster and die shoe, patrix is fixedly connected with below upper bolster, be fixedly connected with side plate above die shoe, above side plate, be fixedly connected with intermediate pads, the counterdie that above intermediate pads, fixed installation is corresponding with patrix, the upper cavity holding workpiece is provided with in the middle of patrix, is provided with the lower chamber holding workpiece in the middle of counterdie, bottom lower chamber, is inlaid with counterdie cushion block, and formed between counterdie cushion block and counterdie and be tightly connected; Counterdie cushion block upper surface is equipped with sawdust layer.
Preferably, described sawdust layer thickness is 0.5-1cm.
Preferably, with bolts between described die shoe and side plate, with bolts between side plate and intermediate pads, with bolts between intermediate pads and counterdie.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
A kind of heading die adopting compressed air type to eject of the present utility model, when utilizing jumping-up, high temperature lights sawdust layer, in the enclosure space at sawdust layer place, form HTHP, mould separately after, form blast, workpiece ejects by the high pressure that blast produces, thus completes whole upset forging process, and this heading die structure is simple, eject action fast, thus the operating efficiency of heading die is effectively provided, ejecting force is large, can the larger heavy forging jumping-up of difficulty action accomplishment, eject.
Accompanying drawing explanation

Heading die structural representation of the present utility model during Fig. 2.
Mark in figure: 1-upper bolster, 2-patrix, 3-counterdie, 4-intermediate pads, 5-side plate, 6-die shoe, 7-sawdust layer, 8-counterdie cushion block, 9-ejector beam for subsequent use, 10-stripper, 11-upper cavity, 12-lower chamber.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, a kind of heading die adopting compressed air type to eject of the present utility model, comprise upper bolster 1 and die shoe 6, patrix 2 is fixedly connected with below upper bolster 1, side plate 5 is fixedly connected with above die shoe 6, intermediate pads 4 is fixedly connected with above side plate 5, the counterdie 3 that above intermediate pads 4, fixed installation is corresponding with patrix 2, the upper cavity 11 holding workpiece is provided with in the middle of patrix 2, is provided with the lower chamber 12 holding workpiece in the middle of counterdie 3, bottom lower chamber 12, is inlaid with counterdie cushion block 8, and formed between counterdie cushion block 8 and counterdie 3 and be tightly connected; Counterdie cushion block 8 upper surface is equipped with sawdust layer 7.The thickness of sawdust layer 7 is 0.5-1cm.With bolts between die shoe 6 and side plate 5, with bolts between side plate 5 and intermediate pads 4, with bolts between intermediate pads 4 and counterdie 3.By counterdie cushion block 8, different thickness can be set, thus guarantee the height of workpiece and the distortion size of workpiece.
Upper bolster 1 is connected with the slide block of hydraulic press, when slide block down, drive die shoe 6 and counterdie 3 descending, extrude the workpiece that is positioned in the lower chamber 12 of counterdie 3, during jumping-up, the temperature of workpiece is generally between 1150 DEG C-900 DEG C, and the workpiece that sawdust layer 7 touches high temperature takes fire, simultaneously, workpiece is subject to patrix 2 applied pressure and starts distortion, now, the enclosure space of the instantaneous formation HTHP in space at sawdust layer 7 place, its pressure exceedes extraneous atmospheric pressure.When slide block is up, drive patrix 2 groups and patrix 2 up, when workpiece loses patrix 2 applied pressure, the space at sawdust layer 7 place bottom workpiece forms blast, upwards ejects workpiece, workpiece and counterdie 3 are thrown off, thus complete ejecting workpiece, and then complete jumping-up operation.
In order to prevent the accident that may occur, namely during jumping-up, the space at sawdust layer 7 place cannot form enclosure space, thus cannot complete blast step, and now workpiece just can not be ejected, therefore ejector beam 9 for subsequent use is provided with in the intermediate pads 4 below counterdie cushion block 8, be provided with stripper 10 bottom ejector beam 9 for subsequent use, stripper 10 laterally passes die shoe 6 and side plate 5, drives stripper 10 up by artificial or other driving mechanisms, ejector beam 9 for subsequent use is up, ejects workpiece.
