The overall shape of the mould matches the cylindrical bearing ring to be treated. The mould comprises an upper die and a lower die, wherein the outer diameter (phi3) of the inner ring of the upper die is equal to the inner diameter (phi1) of the inner ring of the bearing; the width (L1) of the lower tooth of the inner ring of the upper die is longer than the chamfer of the inner diameter surface of the bearing inner ring by 10 mm; the outer diameter (D) of the inner ring platform of the upper die is longer than the outer diameter of the rolling path of the bearing inner ring by 40 mm; the outer diameter (phi3) of the inner ring of the lower die is equal to the inner diameter (phi1) of the inner ring of the bearing; the width (L1) of the lower tooth of the inner ring of the lower die is longer than the chamfer of the inner diameter surface of the bearing inner ring by 10 mm; the outer diameter (D) of the inner ring platform of the lower die is longer than the outer diameter of the rolling path of the bearing inner ring by 40 mm; the total height (h) is equal to half of the height of the bearing inner ring pair; the width (L2) of the upper tooth of the lower die is equal to 10 mm. The mould of the utility model uses less materials The heat treatment quality is high. The utility model is convenient to release by man power. The production efficiency is high.
Description
Technical field
The utility model relates to bearing thermal treatment field, is specifically related to a kind of converted steel bearing ring quenching mould.
Background technology
Just according to the shape of bearing bore diameter, outer raceway, profiling manufacturing fully designs upper die and lower die respectively by 1/2 of inner ring panel height to existing quenching mould.This kind structure design, upper die and lower die volume sum 100% is full of bearing bore diameter, and materials are many, and the heat-treatment quenching cooling performance is poor, and thermal treatment quality is defective, and is not easy very much artificial mould unloading, and production efficiency is low.In recent years, along with the manufacturing development of China, the shape of bearing became increasingly complex, size is increasing, and effective thickness is more and more thicker.Continue method of design, can't satisfy the heat treated requirement of converted steel bearing ring with former Quenching die.
Therefore, provide that a kind of material is few, quenching effect good, that mould unloading is easy to converted steel bearing ring quenching mould is imperative.
The utility model content
Existing quenching mould materials are many in order to solve, quench cooled weak effect, mould unloading difficult technologies problem, and the utility model provides a kind of converted steel bearing ring quenching mould.
The technical scheme that the utility model technical solution problem is taked is following:
Converted steel bearing ring quenching mould; Its global shape and pending cylindrical bearing lasso are complementary; This mould comprises upper die and lower die; The inner ring external diameter of said patrix equals cylindrical bearing inner ring internal diameter, and the inner ring lower tooth width of patrix is than the long 10mm of cylindrical bearing inner ring aperture surface chamfering, and the inner ring platform external diameter of patrix is than the outer path length 40mm of cylindrical bearing inner ring raceway; The inner ring external diameter of said counterdie equals cylindrical bearing inner ring internal diameter; The inner ring lower tooth width of counterdie is than the long 10mm of cylindrical bearing inner ring aperture surface chamfering; The inner ring platform external diameter of counterdie is than the outer path length 40mm of cylindrical bearing inner ring raceway; It is secondary high half that the total height of counterdie equals the cylindrical bearing inner ring, the wide 10mm that equals of the upper tooth of counterdie.
Converted steel bearing ring quenching mould; Its global shape and pending cylindrical bearing lasso are complementary; This mould comprises upper die and lower die; The inner ring external diameter of said patrix equals cylindrical bearing inner ring raceway internal diameter, and the inner ring lower tooth width of patrix is than the long 10mm of cylindrical bearing inner ring aperture surface chamfering, and the inner ring platform external diameter of patrix is than the outer path length 40mm of cylindrical bearing inner ring raceway; The structure of said counterdie and patrix symmetry.
The beneficial effect of the utility model is: upper die and lower die volume sum accounts for less than 1/2 of bearing bore diameter area in the structure design of this mould, and materials are few, the heat-treatment quenching good cooling results, and thermal treatment quality is high, and is very easy to artificial mould unloading, and production efficiency is high.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
The structure design of the utility model converted steel bearing ring quenching mould is divided two kinds of situation:
1) secondary tall and big during when pending converted steel bearing inner race in 250mm, adopt Fig. 1 to be used to upper die and lower die structure shown in Figure 5;
2) when the secondary higher primary school of pending converted steel bearing inner race during, adopt two picture groups 4 and patrix respective outer side edges shown in Figure 5 to use in 250mm.
For above-mentioned first kind of situation; Extremely shown in Figure 5 like Fig. 1, the utility model converted steel bearing ring quenching mould, its global shape and pending cylindrical bearing lasso are complementary; This mould comprises upper die and lower die; The inner ring external diameter Ф 3 of said patrix equals cylindrical bearing inner ring internal diameter Ф 1, and the inner ring lower tooth width L1 of patrix is than the long 10mm of cylindrical bearing inner ring aperture surface chamfering, and the inner ring platform D outer diameter of patrix is than the outer path length 40mm of cylindrical bearing inner ring raceway; The inner ring external diameter Ф 3 of said counterdie equals cylindrical bearing inner ring internal diameter Ф 1; The inner ring lower tooth width L1 of counterdie is than the long 10mm of cylindrical bearing inner ring aperture surface chamfering; The inner ring platform D outer diameter of counterdie is than the outer path length 40mm of cylindrical bearing inner ring raceway; It is secondary high half that the total height h of counterdie equals the cylindrical bearing inner ring, and the wide L2 of the upper tooth of counterdie equals 10mm.
For above-mentioned second kind of situation; Like Fig. 4 and shown in Figure 5, the utility model converted steel bearing ring quenching mould, its global shape and pending cylindrical bearing lasso are complementary; This mould comprises upper die and lower die; The inner ring external diameter Ф 3 of said patrix equals cylindrical bearing inner ring internal diameter Ф 1, and the inner ring lower tooth width L1 of patrix is than the long 10mm of cylindrical bearing inner ring aperture surface chamfering, and the inner ring platform D outer diameter of patrix is than the long 40mm of cylindrical bearing inner ring raceway; The structure of said counterdie and patrix symmetry.
