Abstract
A kind of bearing ring quenching mould, there are composable mold 1 and composable mold 2, the die ontology of composable mold 1 and composable mold 2 is rounded, its two sides is respectively equipped with round upper die and lower die, the upper die of composable mold 1 is identical as the upper die diameter of composable mold 2, the lower die of composable mold 1 is identical as the pushing mode diameter of composable mold 2, and the center of composable mold 1 and composable mold 2 has through-hole.The upper die (or lower die) of composable mold 1 and the upper die (or lower die) of composable mold 2 are connected to each other inside bearing inner race (or bearing outer ring).Sunpender passes through through-hole, is fixed on pallet, and drift passes through sunpender, compresses composable mold 1 and composable mold 2.Using the mold of this structure, than the weight saving 483Kg of original mold, material is saved, cost is reduced, factory is given to save fund, inventory puts saving space occupied, and worker is also convenient to use, and improves production efficiency.
Description
Technical field
The utility model 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 utility model provides a kind of bearing ring quenching mould, it is characterised in that: there is combination die
The die ontology of tool 1 and composable mold 2, composable mold 1 and composable mold 2 is in patty, in patty die ontology two sides point
Not She You circular protrusions, the circular protrusions be upper die and lower die；The diameter of the upper and lower pressing mold of composable mold 1 is less than group
The diameter of molding 1 die ontology of tool, the diameter of the upper and lower pressing mold of composable mold 2 are less than the diameter of 2 die ontology of composable mold,
The upper die of composable mold 1 is identical as the upper die diameter of composable mold 2, under the lower die and composable mold 2 of composable mold 1
Pressing mold diameter is identical, and the upper die of composable mold 1 and the upper die of composable mold 2 protrude into bearing inner race, inside bearing inner race
It is connected to each other, 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, composable mold 1
The lower die of lower die 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
The outer surface of 2 lower die of mold is in contact with the inner surface of bearing outer ring, and the center of composable mold 1 and composable mold 2 is with logical
Hole, sunpender pass through through-hole, are fixed on pallet, and drift passes through sunpender, compress 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, the weight of the utility model is
1704Kg, the weight of original mold are 2187Kg, and the utility model is more this than the weight saving of original mold 483Kg, use
The mold of structure by the calculating of several models, save material, reduce cost by the weight saving of the original mold of weight ratio 25%,
Fund is saved to factory, inventory puts saving space occupied, and worker is also convenient to use, and improves production efficiency.
