Abstract

An upsetting extruding and port cutting combination die for a conical part relates to a die for extruding and punching composite processes of a revolving body part in a punching shaping process, the upsetting extruding and port cutting combination die mainly comprises an upper die formed by an upsetting extruding concave die, a notch concave die, an upper base plate, an upper pressure bar, an upper die plate, and an upper die holder, and a lower die formed by an upsetting extruding convex die, a notch convex die, an edge material cutter, a lower base plate, a lower pressure bar, a lower die plate, and a lower die holder; the internal of the central holes of the upper and lower die holders are provided with oil cylinders, pistons, and bearing plates; when upsetting extruding of the part is completed, excess materials at the port of the part are cut via relative movement of the notch convex die and the notch concave die; and the upsetting extruding and port cutting combination die in the utility model is advantaged by reduction of production processes and good consistency of inner shape and height of the component.

Description

A kind of conical part upsetting squeeze, cut the port combination mould

Technical field

The utility model belongs to the punch process technical field, relate in the process for stamping and forming revolving parts squeeze, towards the combination process device, particularly a kind of conical part upsetting squeeze, cut the port combination mould.

Background technology

Shape and the higher revolving body cone spinning part of height dimension required precision in a kind of, in the spinning process part head influenced by jacking block can't attenuation and part port part irregular, part is carried out upsetting squeeze with need or machine adds head and car port operation; Because the follow-up location once more of part causes interior shape of part and height dimension uniformity poor.

Summary of the invention

The defective of shape and height dimension uniformity difference in the utility model mainly solves after the cone spinning part processing that exists in the prior art; And a kind of upsetting squeeze that proposes, cut the port combination mould; Thereby reduce part location number of times, reach the purpose of interior shape of part and height dimension high conformity.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:

A kind of conical part upsetting squeeze, cut the port combination mould, comprise upsetting squeeze die, upsetting squeeze punch, otch punch, otch die, rim charge cutter, upperpush rod, down-pressed pole and upper padding plate, lower bolster, cope match-plate pattern, lower bolster, upper bolster, die shoe.It is characterized in that said upsetting squeeze die is contained in no gap in the centre bore of otch die movingly, the upsetting squeeze die expands platform and on the otch die, touches mutually with upperpush rod expansion you face is coaxial; Said upper padding plate and cope match-plate pattern are enclosed within the upsetting squeeze die with matched in clearance respectively and expand outside platform and the upperpush rod, and upper padding plate is positioned under the cope match-plate pattern; Otch die hold-down screw passes cope match-plate pattern, upper padding plate and otch die successively and is connected; Said upper bolster is coaxial and connect screw with cope match-plate pattern and connect to form patrix with cope match-plate pattern;

Said rim charge edge is enclosed within the otch punch up and expands on the platform, and wherein: the upsetting squeeze punch is contained in no gap in the centre bore of otch punch movingly, and touch with down-pressed pole expansion you face is coaxial mutually upsetting squeeze punch lower end; Said lower bolster and lower bolster are enclosed within outside the down-pressed pole with matched in clearance respectively under the otch punch, and lower bolster is positioned on the lower bolster; Otch punch hold-down screw passes lower bolster, lower bolster and otch punch successively and is connected, and die shoe is coaxial and connect screw with lower bolster and connect to form counterdie with lower bolster;

Upper cylinder, upper piston are housed in the said upper bolster centre bore, go up bearing plate; Oil cylinder, lower piston and following bearing plate are housed down in the die shoe centre bore;

Said upper cylinder and the external hydraulic oil pipe of following oil cylinder difference, hydraulic oil pipe system provides the oil pipe hydraulic pressures respectively.

The utility model compared with prior art has following beneficial effect:

1, the utility model reduces production process, and one-time positioning is accomplished upsetting squeeze and cut the port two procedures;

2, shape and height high conformity in the part of the utility model processing;

3, the utility model is that like parts processing provides a kind of new method.

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, a kind of conical part upsetting squeeze, cut the port combination mould.This assembling die comprises upsetting squeeze die 12, upsetting squeeze punch 8, otch punch 9, otch die 11, rim charge cutter 10, upperpush rod 21, down-pressed pole 3, goes up bearing plate 19, following bearing plate 5, upper padding plate 13, lower bolster 2, cope match-plate pattern 16, lower bolster 7, upper bolster 17, die shoe 1; Said upsetting squeeze die 12 is installed in no gap in the centre bore of otch die 11 movingly, and upsetting squeeze die expansion platform 14 is positioned on the otch die 11 and touches mutually with upperpush rod expansion platform 15 end faces are coaxial; Said upper padding plate 13 is enclosed within the upsetting squeeze die with matched in clearance respectively with cope match-plate pattern 16 and expands outside platform 14 and the upperpush rod 21, and upper padding plate 13 is positioned under the cope match-plate pattern 16; Otch die hold-down screw 23 passes cope match-plate pattern 16 successively, upper padding plate 13 is connected with otch die 11; Said upper bolster 17 and cope match-plate pattern 16 are coaxial and connect screw 22 through cope match-plate pattern and connect to form patrix;

Said rim charge cutter 10 up-bite jaws are enclosed within the otch punch and expand on the platform 25, and wherein: upsetting squeeze punch 8 is installed in no gap in the centre bore of otch punch 9 movingly, and touch with down-pressed pole expansion platform 27 end faces are coaxial mutually upsetting squeeze punch 8 lower ends; Said lower bolster 2 is enclosed within outside the down-pressed pole 3 with matched in clearance respectively under otch punch 9 with lower bolster 7, and lower bolster 2 is positioned on the lower bolster 7; Otch punch hold-down screw 26 passes lower bolster 7, lower bolster 2 successively and is connected with otch punch 9, and die shoe 1 and lower bolster 7 are coaxial and connect to form counterdie through lower bolster connection screw 28;

Upper cylinder 18, upper piston 20 are installed in said upper bolster 17 centre bores, go up bearing plate 19; Oil cylinder 6, lower piston 4 and following bearing plate 5 are installed down in die shoe 1 centre bore;

Said upper cylinder 18 and the external hydraulic oil pipe of following oil cylinder 6 difference, hydraulic oil pipe system provides the oil pipe hydraulic pressures respectively.

Method for using: the part behind the spinning 24 is enclosed within on the upsetting squeeze punch 8; When otch die 11 comes downwards to upsetting squeeze die 12 and contacts with part; Bearing plate 5 and then promotion down-pressed pole 3 moved upward upsetting squeeze punch 8 under lower piston 4 promoted, and meanwhile upper piston 20 promotes to go up bearing plate 19 and then promotes upperpush rod 21 upsetting squeeze die 12 is moved downward, and begins part 24 upsetting squeezes; Accomplish up to part 24 upsetting squeezes; This moment, 11 continuation of otch die were descending, and until contacting with otch punch 9 upper surfaces, part port part excess stock receives the outside slippage of effect of otch punch 9 in this course.The excess stock that otch die 11 contact is shifted out, and it is descending to push away excess stock, is excising excess stock down with the effect of otch punch 9.Part 24 withdraws from from otch die 11 and otch punch 9 respectively under the effect of upsetting squeeze punch 8 and upsetting squeeze die 12 and respective pistons during backhaul; The excess stock of cutting is repeatedly being pushed to rim charge cutter 10 by otch die 11 in the processing, is cut off by rim charge cutter 10.
