Description
Technical field
The present invention relates to field of bearings, and in particular to the mold used when a kind of large-scale bearing ring carburizing and quenching.
Background technique
The outer ring of the serial large-scales cylinder roller bearing such as NNU41/600M at present, interior loop material are all carburizing steel, carburizing steel
Heat treatment process is more complicated, and such big style ferrules carburizing hardness depth is greater than and is equal to 4.0mm, and lasso heats in furnace
Carburizing time is long, is up to for more than 130 a hours, deforms after carburizing primary quenching larger, and reheating quenching needs to use shaping
Pressing mold prevents lasso from deforming, and prevents to will appear waste product, the lasso carburizing and quenching shaping pressing mold quantity of this series bearing compares
More, there are two outer ring shaping pressing mold, two inner ring shaping pressing molds, outer ring shaping pressing molds to be divided into upper mold for the bearing of a model, under
Mould.Inner ring shaping pressing mold is also classified into upper mold, lower die.There are four shaping pressing molds for bearing a set of in this way.Every batch of product, which is finished, to be put into
Ku Li is saved, and the product that the time has grown carburizing is more, and shaping pressing mold is also more, is put in warehouse and is occupied many places, a production
Four shaping pressing molds of product model, sometimes four shaping pressing molds are not put together, are got and are backtracked when worker receives every time, the time
Grow more troublesome, worker feels very worried, while affecting working efficiency, has delayed manufacturing schedule.
Summary of the invention
To solve the above problems, the present invention provides a kind of bearing ring quenching mould, it is characterised in that: there is composable mold 1
With composable mold 2, the die ontology of composable mold 1 and composable mold 2 is in patty, is set respectively in patty die ontology two sides
There are circular protrusions, the circular protrusions are upper die and lower die；The diameter of the upper and lower pressing mold of composable mold 1 is less than combination die
Has the diameter of 1 die ontology, the diameter of the upper and lower pressing mold of composable mold 2 is less than the diameter of 2 die ontology of composable mold, combination
The upper die of mold 1 is identical as the upper die diameter of composable mold 2, the pushing of the lower die and composable mold 2 of composable mold 1
Mode diameter is identical, and the upper die of composable mold 1 and the upper die of composable mold 2 protrude into bearing inner race, the phase inside bearing inner race
Docking, the outer surface of 2 upper die of composable mold 1 and composable mold is in contact with the inner surface of bearing inner race, under composable mold 1
The lower die of pressing mold and composable mold 2 protrudes into bearing outer ring, is connected to each other in the inside of bearing outer ring, composable mold 1 and combination die
The outer surface for having 2 lower dies is in contact with the inner surface of bearing outer ring, and the center of composable mold 1 and composable mold 2 has through-hole,
Sunpender passes through through-hole, is fixed on pallet, and drift passes through sunpender, compresses composable mold 1 and composable mold 2.
The upper die of composable mold 1 and the upper die of composable mold 2 protrude into bearing inner race, opposite inside bearing inner race
It connects, the outer surface of 2 upper die of composable mold 1 and composable mold is in contact with the inner surface of bearing inner race, plays the role of being to protect
It is indeformable in quenching process to demonstrate,prove bearing inner race.The lower die of composable mold 1 and the lower die of composable mold 2 protrude into bearing outer ring,
It is connected to each other in the inside of bearing outer ring, the outer surface of 2 lower die of composable mold 1 and composable mold and the inner surface phase of bearing outer ring
Contact is played the role of being to guarantee that bearing outer ring is indeformable in quenching process.
Using the mold of this structure, instead of original four single entries shaping pressing mold, weight of the invention is
1704Kg, the weight of original mold is 2187Kg, the present invention than original mold weight saving 483Kg, using this structure
Mold by the calculating of several models, the weight saving of the original mold of weight ratio 25% saves material, reduces cost, give
Factory saves fund, and inventory puts saving space occupied, and worker is also convenient to use, and improves production efficiency.
