The upper and lower dies are provided with positioning guide plugs and fixed structures of an upper and a lower die seats. The utility model has the advantages of easy fabrication, convenient operation, obvious material saving and high forging quality, solves the problems of the wad in inner holes and material waste of the common die forging pieces, and achieves the production level of specialized machines by using conventional equipment. The utility model can enhance the production efficiency by 1.5 times, and the long lifetime of the forging moulds can be enhanced by 1 to 1.5 times.

Description

Ring shaped forging non-contacted thin-sheet mould

The utility model relates to the die forging technical field.

General ring shaped forging stamp forging mould all is at die cavity height intermediate section mould, and there is the core rod (inner core) of last lower convexity at the mould center, occurs gross weight between the core rod.The endoporus of forging is big more, and gross weight is also big more.Not only wasted the material and facility energy, and increased mould and operation, reduced the forging die life-span towards the endoporus gross weight, time-consuming.

The purpose of this utility model provides a kind of ring shaped forging non-contacted thin-sheet mould, and it is rational in infrastructure, has solved the gross weight problem, and energy-saving material-saving has improved production efficiency and forging quality, has prolonged die life, has reduced production cost.

Technical essential of the present utility model is: a kind of ring shaped forging non-contacted thin-sheet mould, it is characterized in that having upper and lower mould, there are the core rod and the counterdie of a band pattern draft to fuse, patrix has core rod top mating surface, the die joint in the die cavity outside is provided with flash gutters, and upper and lower mould is provided with location guide gip and upper and lower die holder fixed structure.

In order to prevent the company of flying at core rod top better, the core rod top preferably has the straight garden shell of column that exceeds hot forging 3-6mm, when die forging, can produce drag effect to metal, can guarantee better that end face does not have burr, and metal is full of die cavity again easily.Above-mentioned flash gutters can be the flash gutters of being with the overlap bridge, can be common flash gutters also, is preferably the expanding flash gutters.Above-mentioned pattern draft is best for being 10-12 °.Above-mentioned die joint can be located at a side of die cavity, or middle.In order to prevent have dirts such as oxide skin to influence the tight engagement of upper and lower mould on the core rod end face, be preferably in the gap that mold and core rod top mating surface have 0.5-1mm.Convenient for depanning, can on the counterdie in the flash gutters outside, be provided with 1,2 or a plurality of die sinking sled groove.Above-mentioned upper and lower mould and upper and lower mould seat holding structure, can be on upper and lower die holder, to be equipped with corresponding matching fixing dovetail groove and dovetails, being preferably upper and lower mould is equipped with and uses dormant bolt, as fastening templates such as hexagon socket head cap screws, utilize pressing plate upper and lower mould can be contained on the upper and lower die holder securely.

Effect of the present utility model is significantly, and it makes simple, and is easy to operate, efficiently solves the difficult problem that common forging part has endoporus gross weight waste material.Its material-saving is obvious, and production efficiency can improve 1.5 times, and the die forging life-span can be improved 1-1.5 doubly, simultaneously the forging quality height.Use conventional equipment, can reach the level of production of special plane, have general application value as friction press and various pneumatic hammer.

Describe in detail below in conjunction with embodiment and accompanying drawing, but not as to qualification of the present utility model.

Fig. 1 is the structural representation of embodiment 1.

Fig. 2 is the vertical view of Fig. 1 counterdie 7.

Among Fig. 1, Fig. 2,5 countersunk head hexagon socket head cap screws 1 are fixed on patrix 3 on the cope match-plate pattern 2,5 countersunk head hexagon socket head cap screws 9 are fixed on counterdie 7 on the lower bolster 8,2 guide gips 10 are fixed on the counterdie, and and patrix 3 in the hole be slidingly matched, the band pattern draft core rod 4 and counterdie 7 be connected as a single entity, and be higher than die cavity 3mm, exceed the Duan Weiyuan cylindricality, 5 are the expansion flash gutters, and 2 die sinking sled grooves 6 are on counterdie 7.The intermediate section mould.

Utilize the continuous jacking blank-making technology of the utility model mould and flat-die hammer to produce automobile size locknut, can save material 0.5-0.8 doubly, obvious energy conservation can improve 1.5 times die life, and forging quality and productivity ratio improve greatly.Three kinds of forging contrasts are as follows:

(1) material-saving is remarkable

Table 1 Sequence number The forging title Every chassis number of packages Former Forging Technology New forging method technology Blank weight (kg) Forge weight (kg) Blank weight (kg) Forge weight (kg) 1 Big locknut ??6 ????4.9 ????3.6 ????4.9 ???1.9 2 Little locknut ??6 ????3.25 ????1.7 ???1.1 3 Locking is female ??1 ????1.07 ????0.48 ???0.48 Add up to ??13 ????9.22 ????5.78 ????4.9 ???3.48

Find out that from table one three kinds of forging material therefors of new forging method are than 0.86 times of former technology joint steel, forging has been refined 0.76 times than raw material, and chassis joint 45# steel 20.57kg by producing 3000 calculating per year, can save 62 tons every year.

(2) energy-conservation obvious

(1) heating aspect, each needs heating one fire when forging with three kinds of parts of former process, and new forging method can be forged by a fire continuously, and economizing on coal can reach 0.7-1.0 doubly.

(2) equipment aspect, 1. forging equipment is energy-conservation.As big locknut forging, adopt direct die forging, the endoporus gross weight just accounts for 2/3 of forging projected area, and the big tonnage of equipment that just needs of projected area is big, do not have the endoporus gross weight with new technology, but skinny device is done big part, has saved kinetic energy.2. blanking equipment is energy-conservation.The following three kinds of material of former three kinds of parts, an original material is dried under the new forging method becomes three kinds of parts, has both economized equipment, again when segment saw gate material and blankers.

(3) labor productivity improves

Table 2 Sequence number The forging title Every chassis number of packages Labor productivity (part/day people) Former technology New forging method technology 1 Big locknut ??6 ????20 ?????50 2 Little locknut ??6 ????25 ?????50 3 Lock sleeve ??1 ????25 ?????50 Add up to ??13 ????70 ?????150

Find out by table 2, adopt new forging method, can boost productivity greatly, bring up to 150/day people, be enhanced about more than once from 70/day people of original three kinds of totals.

Four, cost of parts descends obviously

By forging cost accounting, part processing is saved time cost and is adjusted, and the cost of part can be reduced below one times, has realized significant overall economic efficiency.
