Abstract
The utility model relates to a quenching die for a large-scale carburizing steel self aligning roller bearing outer ring, which is assembled by a pallet, a base plate, a lower die, an upper die, an iron wedge, a hanging rod, a positioning cover and a plurality of sliding pins, wherein the hanging rod penetrates through a central hole of the base plate, and the base plate is arranged on the upper end surface of the pallet in a matching way; the upper end surface of the base plate is of a slope surface, and a plurality of pin holes are uniformly distributed on the base plate; a sliding pin is arranged in each pin hole to be used as a guide column, and the lower die consists of a plurality of die segments; each die segment of the lower die is put on the base plate according to the set position, and after each segment of the lower die is furled by a steel wire, the positioning cover is embedded in an annular groove on the upper end surface of the lower die, so that the spherical outer diameter of the lower die is smaller than the outer diameter of the bearing outer ring; the outer ring is sleeved on the lower die after carburizing before quenching, the positioning cover is lifted, the upper die is put in, and the iron wedge is embedded in an oblique hole at the upper part of the hanging rod; and the spherical surface is contacted with the an outer ring raceway. The carburized layer of the raceway is uniform, the carburized and quenched die spherical surface needs to be fully in contact with the raceway, so that the labor intensity is reduced, the operability is strong, and the quenching performance is good.
Description
Technical field
The utility model relates to a kind of quenching mould, particularly relates to a kind of large-scale converted steel self-aligning roller bearing ring carburizing and quenching mould.
Background technology
Traditional carburizing and quenching pressing mold contact inner radius outside workpiece is straight, can not contact on raceway, the converted steel product all has the back middle raceway that quenches to shrink serious characteristics, so cause product cementation zone inequality, middle raceway hardness does not reach technical requirements, and such Quenching die is not suitable for the carburizing and quenching that material is the converted steel self-aligning roller bearing.
The structure of the carburizing and quenching pressing mold of present small-sized converted steel self-aligning roller bearing, contact is shunk pulling at several petals of raceway by the spring location, pallet is flat, and the product external diameter surpasses the above large-scale self-aligning roller bearing ring of Φ 500mm, and empirical tests can not be used this structure.
There are certain mismachining tolerance in the raceway shape and the allowance of the similar large product of original production, cause carburizing and quenching with a collection of product after, the shrinkage of raceway is not of uniform size, cementation zone and hardness do not guarantee like this.
The utility model content
The purpose of this utility model provides a kind of large-scale converted steel self-aligning roller bearing outer ring quenching mould, has alleviated working strength of workers, and the cementation zone and the hardness of bearing outer ring are guaranteed, and improves the quenching quality of bearing outer ring.
The technical scheme that adopts is:
Large-scale converted steel self-aligning roller bearing outer ring quenching mould is assembled into by pallet, chassis, counterdie, patrix, drift, suspension rod, location lid and a plurality of sliding pin, it is characterized in that:
Suspension rod passes the centre hole on chassis; The chassis coupling is installed on the upper surface of pallet, and the upper surface on chassis is domatic, is evenly equipped with a plurality of pin-and-holes on the chassis; Be equiped with sliding pin in each pin-and-hole, as guidepost; Counterdie is made up of a plurality of mould lobes, and each mould lobe of counterdie is placed on the chassis by desired location, draw each mould lobe of counterdie in steel wire after, the location lid is embedded in the ring groove of counterdie upper surface, make the external diameter of counterdie sphere external diameter less than bearing outer ring; The preceding outer ring of quenching is sleeved on the counterdie after the carburizing, hangs a liter location lid, puts into patrix, and drift embeds in the inclined hole on suspension rod top; The sphere of counterdie contacts with outer ring raceway.
Advantage of the present utility model is:
The cementation zone of the utility model raceway is even, and carburizing and quenching pressing mold sphere must contact roller surface fully, and the labour intensity that alleviates the operator is workable, and the quenching performance is good.We have carried out design improvement to former Quenching die for this reason, removed the spring location of former Quenching die, having improved the chassis is the structure of inclined-plane and band chute, optimization design the physical dimension of rational Quenching die, in order to make workpiece quenching performance good, become vertically and axially to have the structure of oil groove in the surface design of each Quenching die lobe, wherein counterdie is made of the 6-12 lobe according to the bearing products size, whole processing back excision forming, Quenching die as shown in Figure 1.
Before the quenching, each lobe of counterdie is assembled on the chassis by auxiliary means, the inclined-plane of upper and lower mould and drift imbeds outer ring raceway with each lobe of counterdie during quenching, makes it to obtain uniform cementation zone and hardness.
Improvement by carburizing and quenching pressing mold and technology has alleviated working strength of workers, makes the cementation zone of product and hardness obtain effective assurance, thereby has improved the work-ing life of bearing, has obtained user's approval.
