Abstract

The utility model discloses a floating gear finishing forging die which comprises an upper die plate, a lower die plate, a floating plate, four guide posts and four guide sleeves. The four guide posts are fixed to the lower die plate. The four guide sleeves are fixed to the upper die plate. Each guide sleeve is arranged on the corresponding guide post. Four copper sleeves are fixed to the floating plate. The four guide posts are sleeved with the four copper sleeves. A lower die composed of a lower die core, a middle lower die sleeve and an outer lower die sleeve is installed on the floating plate. An upper die cushion plate is fixed to the lower portion of the upper die plate. An upper die is fixed to the upper die cushion plate through an upper die pressing ring. An upper die core is installed in the middle of the upper die. A lower die cushion plate is fixed to the upper portion of the lower die plate. An ejector rod is installed in the middle of the lower die cushion plate. An ejection block is installed in the lower die. The floating gear finishing forging die has the advantages that the gear shape of a large gear can be successfully forged, the problem that the gear shape of the large gear is difficult to form is solved through following gear shape cold refined pushing, the material use rate and the production efficiency are improved, and adaptability is good.

Description

Floating type gear finisher

Technical field

The utility model relates to a kind of mould structure, particularly a kind of floating type gear finisher.

Background technology

Existing straight tooth column dish gear forming mode mainly contains following two kinds: 1, forge hot tooth base adds machining, and this is traditional gear working method, is of wide application.Its shortcoming is, profile of tooth is forged not out, and stock utilization is low, and machining workload is large, and production efficiency is low.2, cold extrusion shaped.Be only applicable to the gear forming that outside circle is less, modulus is less.Adaptability scope is little.

Utility model content

This practical technical problem to be solved is for the deficiencies in the prior art, and a kind of floating type gear finisher is provided.

To achieve these goals, the measure that the utility model is taked:

Floating type gear finisher, comprise cope match-plate pattern, lower bolster, float plate, four guide pillars and four guide pin bushings, four described guide pillars are fixed on lower bolster, four guide pin bushings are fixed on cope match-plate pattern, guide pin bushing is arranged on guide pillar, in float plate, be fixed with four copper sheathings, four copper sheathings are enclosed within on four guide pillars, in float plate, be provided with by lower mold core, the counterdie that in counterdie, cover and counterdie overcoat form, cope match-plate pattern bottom is fixed with upper die plate, on upper die plate, by patrix trim ring, be fixed with patrix, upper mold core is installed in the middle of patrix, lower bolster top is fixed with counterdie backing plate, ejector beam is installed in the middle of counterdie backing plate, jacking block is installed in counterdie,

Six roots of sensation Compress Spring and six stop screws are installed between described lower bolster and float plate.

The beneficial effects of the utility model: practicality, production cost is low, easy to use, can successfully forge the profile of tooth compared with gear wheel, then push by the cold essence of postorder profile of tooth, solve compared with the problem of gear wheel profile of tooth difficult forming, avoided the gear mechanism processing link of the heavy and poor efficiency such as gear hobbing, gear shaping, shaving, improved stock utilization and production efficiency, adaptability is good, is applicable to electric screw press, double disk friction screw press, hotdie forging press, open and close type punch press, hydraulic press etc.

The specific embodiment

Floating type gear finisher, comprise cope match-plate pattern 8, lower bolster 1, float plate 4, four guide pillars 6 and four guide pin bushings 7, four described guide pillars 6 are fixed on lower bolster 1, four guide pin bushings 7 are fixed on cope match-plate pattern 8, guide pin bushing 7 is arranged on guide pillar 6, four guide pole die carriers that guiding is accurate and firm have been formed, in float plate 4, be fixed with four copper sheathings 5, four copper sheathings 5 are enclosed within on four guide pillars 6, float plate 4 can slide up and down along guide pillar 6, in float plate 4, be provided with by lower mold core 14, in counterdie, overlap 15 and the counterdie that forms of counterdie overcoat 16, cope match-plate pattern 8 bottoms are fixed with upper die plate 9, on upper die plate 9, by patrix trim ring 13, be fixed with patrix 12, upper mold core 10 is installed in the middle of patrix 12, lower bolster 1 top is fixed with counterdie backing plate 3, ejector beam 2 is installed in the middle of counterdie backing plate 3, jacking block 17 is installed in counterdie, the position that six roots of sensation Compress

Spring

19 and 18, six stop screws 18 of six stop screws can limit float plate 4 is installed between described lower bolster 1 and float plate 4.

In use, counterdie in lower mold core 14, counterdie, overlap 15 and counterdie overcoat 16 prestressing combination form, counterdie upper surface is higher than jacking block 17 upper surfaces, the distance exceeding is greater than the height of tooth base (blocking is good).The tooth base that blocking is good is put into counterdie, and patrix 12 is descending with press ram, contacts location in advance with lower die orifice; Patrix 12 promotion counterdies and float plate 4 are descending together subsequently, and six roots of sensation Compress Spring 19 is gradually reduced; And then patrix 12 contacts with tooth base, in the die cavity forming, completes tooth base to the moulding of gear at patrix 12, upper mold core 10, jacking block 17 and counterdie.Press ram drives patrix 12 backhauls; Counterdie and float plate 4, under the effect of six roots of sensation Compress Spring 19, also rise thereupon, rise to while contacting with six stop screws 18 and stop; Ejector beam 2, under the effect of forcing press ejecting mechanism, upwards promotes jacking block 17 gear is ejected, and subsequently, jacking block 17 and ejector beam 2 reset, and complete a working cycles, thereby realize the purpose of this utility model.
