Abstract

A cemented steel cylindrical hole bearing ring quenching assembling die comprises a lower die, a die core composed of six die petals with the same structure, an upper die, a locking drill key and a hanger rod, wherein the lower die is provided with a stepped center hole and a die core groove; the upper die is provided with a cone part; the inclined angle of the outer conical surface of the cone part is 15 degrees; an inner conical surface with the inclined angle of 15 degrees is formed on the inner wall of the upper part of each die petal; the lower die is horizontally arranged; the lower ends of the six die petals are respectively placed in the die core groove of the lower die; the cone part of the upper die is inserted in the die core composed of the six die petals; the outer conical surface of the upper die is contacted with the inner conical surfaces of the six die petals in a matching manner respectively; a drill key through hole is formed in the upper end of the hanger rod; a hanger rod cap is arranged at the lower end of the hanger rod; after the upper end of the hanger rod penetrates through the stepped center hole of the lower die and the upper die, the locking drill key is inserted in the drill key through hole in the upper end of the hanger rod, so that the assembling die is obtained. The assembling die provided by the utility model can improve the manufacturing quality of bearing rings, be used repeatedly and reduce the labor intensity of operators.

Description

A kind of converted steel material bearing with cylindrical bore ring quenching assembling die

Technical field

The utility model relates to bearing parts manufacturing technology field, particularly relates to a kind of super-huge converted steel material bearing with cylindrical bore ring quenching assembling die.

Background technology

Current super-huge converted steel material bearing with cylindrical bore ring quenching mould is fixed, with the endoporus contact part, is designed to 10 ' draft angle, and after quenching, the workman pounds mould get off with hammer, and labour intensity is very high.The bearing ring narrow for end face can also be pounded, but the opposite end face width due to mould and endoporus contact area, greatly often pound to get off, have to fall by vertical handlebar mould vehicle, cause mould to scrap.And the existence due to draft angle, inevitably make endoporus be two ends large, middle little shape, cause the finished product quench-hardened case in uneven thickness.

The utility model content

The purpose of this utility model, be to provide a kind of converted steel material bearing with cylindrical bore ring quenching assembling die, can improve the workmanship of bearing ring, and mould can repeatedly use, and can alleviate operator's labour intensity.

The technical scheme adopted is:

A kind of converted steel material bearing with cylindrical bore ring quenching assembling die, comprise counterdie, the core rod, patrix, locking drift and the suspension rod that are comprised of six identical mould lobes of structure, it is characterized in that:

Counterdie has staged centre hole and core rod groove;

Patrix has conical part, and the angle of inclination of the male cone (strobilus masculinus) of conical part is 15o;

The upper inside wall of mould lobe has the inner conical surface at 15o inclination angle;

Counterdie is horizontally disposed with, six mould lobes are along the circumferential direction evenly laid, the lower end of six mould lobes is placed in respectively in the core rod groove on counterdie, the conical part of patrix inserts in the core rod be comprised of six mould lobes, the male cone (strobilus masculinus) of patrix contacts with the inner conical surface coupling of six mould lobes respectively, and the upper end of six mould lobes is supported respectively on the ring platform of patrix;

There is the drift through hole suspension rod upper end, and there is the suspension rod cap suspension rod lower end, and the suspension rod upper end is through after the staged centre hole and patrix of counterdie, and the drift through hole of the locking laterally inserted suspension rod of drift upper end, obtain.

Core rod is to be cut into six lobes that structure is identical after whole machine-shaping to form.

During use, the lasso that is heated to quenching temperature is placed on counterdie, is enclosed within the core rod outside, then with patrix, six mould lobes are strutted to setting size, ring face or mould lobe end face location, the patrix upper surface is with locking drift through boom hole interference locking.Form super-huge converted steel material bearing with cylindrical bore ring quenching molectron.Suspension hook hooks suspension ring, and this molectron is hung in to the quenching oil quenching, after completing air cooling to the mould unloading temperature, the locking drift of backing off, mould and lasso are separable, complete a working cycle.Next can carry out next working cycle, go round and begin again.

Together with the utility model can be avoided lasso and mould " glues ", operator's locking drift of dismantling, mould and lasso are separable, and core rod outside surface vertical and horizontal are designed with the stream oil groove, the lasso internal surface is fully contacted, to guarantee surface hardness and depth of hardening zone with quenching oil.Mould can repeatedly be used, and alleviates operator's labour intensity, economical and practical.

Embodiment

A kind of converted steel material bearing with cylindrical bore ring quenching assembling die, comprise counterdie 1, the core rod 6 be comprised of six identical mould lobes 2 of structure, patrix 3, locking drift 4 and suspension rod 5, it is characterized in that:

Counterdie 1 has staged centre hole 7 and core rod groove 8;

Patrix 3 has conical part 9, and the angle of inclination of the male cone (strobilus masculinus) 10 of conical part 9 is 15o;

The upper inside wall of mould lobe 2 has the inner conical surface 11 at 15o inclination angle;

Counterdie 1 is horizontally disposed with, six mould lobes 2 are along the circumferential direction evenly laid, the lower end of six mould lobes 2 is placed in respectively in the core rod groove 8 on counterdie 1, the conical part 9 of patrix 3 inserts in the core rod be comprised of six mould lobes 2, the male cone (strobilus masculinus) 10 of patrix 3 contacts with inner conical surface 11 couplings of six mould lobes 2 respectively, and the upper end of six mould lobes 2 is supported respectively on the ring platform 12 of patrix 3;

There is drift through hole 13 suspension rod 5 upper ends, and there is suspension rod cap 14 suspension rod 5 lower ends, and suspension rod 5 upper ends are through after the staged centre hole 7 and patrix 3 of counterdie 1, and the drift through hole 13 of the locking laterally inserted suspension rod of drift 45 upper ends, obtain.

Core rod 6 is to be cut into six lobes that structure is identical after whole machine-shaping to form.
