Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, embodiments of the utility model; all other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The following describes in further detail the embodiments of the present utility model with reference to the accompanying drawings: the split quenching die for the large bearing ring comprises a right half die 1 and a left half die 2, wherein the right half die 1 and the left half die 2 are of symmetrical structures, the middle parts of the right half die 1 and the left half die 2 are connected together through a bolt 3 and a nut 4, and the outer end face of the right half die is clamped on the inner contour of a bearing ring 5;

the right half mould 1 comprises an arc supporting plate 11, a vertical lacing wire 12 and a horizontal lacing wire 13, wherein a groove 14 is formed in the outer circle outline of the arc supporting plate 11, and the shape of the groove 14 is matched with the inner outline of the bearing ring 5; a vertical lacing wire 12 is arranged between the upper opening and the lower opening of the circular arc supporting plate 11, and a horizontal lacing wire 13 is arranged between the vertical lacing wire 12 and the circular arc supporting plate 11; a plurality of connecting holes 15 are uniformly distributed on the end surface of the vertical lacing wire 12, and the positions of the connecting holes 15 of the right half die 1 and the left half die 2 are matched; the bolt 3 is penetrated in the connecting hole 15 and is fixed through the nut 4; in actual use, the grooves 14 are clamped on the inner contour of the bearing ring 5 through the bolts 3 and the nuts 4 and are mutually attached, and the depth of the grooves 4 is such that the bearing ring 5 cannot slide from the grooves 4; at the joint of the right half mould 1 and the left half mould 2, a certain gap exists between the right half mould 1 and the left half mould 2, and the smaller gap for the large-sized bearing ring 5 does not affect the whole process size of the bearing ring 5 after quenching, but the size of the gap is reduced as much as possible in the application process so as to reduce errors caused by quenching; in the present embodiment, three bolts 3 and nuts 4 are taken as an example, but in actual use, the number and positions of the bolts 3 and nuts 4 may be changed according to the size of the specific bearing ring 5; the main function of the bolts 3 and nuts 4 is to fix the relative positions of the right half mold 1 and the left half mold 2 so as not to move and be detachable, and other fixing devices can be used according to the use requirements in the application process, and are not specifically described in the example;
