Description
Technical field
The present invention relates to horizontal digital-control Ring Rolling Machine cone roller technical fields, and in particular to a kind of bearing ring processing Ring Rolling Machine cone
Roller two metal solder method.
Background technique
Cone roller is the important component of horizontal digital-control Ring Rolling Machine equipment, by using wear-resisting, heat proof material is welded, can be made
Ring Rolling Machine equipment safety efficiently, is steadily run, and is improved operation rate, is reduced maintenance capacity, extends service life of equipment, drop
Low production cost and worker's amount of labour.But the deficiency of existing ring rolls cone roller material wear ability, it causes maintenance capacity high, uses
Service life is short.
Summary of the invention
In order to solve the problems existing in the prior art, the present invention provides a kind of bearing ring processing Ring Rolling Machine cone roller bimetallic weldering
Connect method.The service life of equipment part is improved, entreprise cost is reduced, ensures product quality.
Technical scheme is as follows: a kind of bearing ring processing Ring Rolling Machine cone roller two metal solder method, cone roller are adopted
With two metal solder, solder wire material is wear-resisting, heat proof material, and heat treatment is passed through before welding and after welding.
Further, the cone roller material of main part be 42CrMo alloy, solder wire material be 5CrMnMo alloy or
5CrNiMo alloy.
Further, temperature is 40-60 DEG C before welding, and annealing temperature is cooling after being 700-750 DEG C of holding 8 hours.
Further, cone roller is preheating to 200-300 DEG C before welding, heat preservation starts to weld when being cooled to 40-60 DEG C, rotates
Motor drives cone roller rotation, heater heating；After welding, starting motor, heater control temperature in 700-750
It is cooling after DEG C being kept for 8 hours, when temperature controller show 80 DEG C, opens water pump and cool down and continues 10 hours.
Further, double-metal layer is with a thickness of 12-16mm.
Beneficial effects of the present invention are as follows: cone roller is handled using two metal solder method, and wear-resisting, high temperature resistant anti-is burst.Cone
Roller service life improves 10 times, greatlys save material, improves operation rate, reduces entreprise cost, guarantees forging products matter
Amount.

Specific embodiment
The present invention is described further by 1-2 with reference to the accompanying drawing.
Embodiment 1
As shown in attached drawing 1-2, a kind of device packet that bearing ring processing Ring Rolling Machine cone roller two metal solder method uses
Include cone roller 1, heating device 2；Described 1 one end of cone roller is protruded into heating device 2, and the other end connects motor 11 by clamp 12,
The motor 11 is fixed on motor cabinet 10, connects cooling water tank 7, cooling water by V-type bracket 6 below the cone roller 1
Water pump 9, water pipe 13, spray head 14 are connected above case 7, temperature controller 3 and heater 4 are equipped in the heating device 2, and described adds
Mobile wheel 5 is equipped with below thermal 2.
Welding process is as follows: it is welded using 5CrMnMo welding wire, makes special heating and cooling cone roller apparatus first,
1 weld preheating temperature of cone roller reaches 200-300 DEG C of heat preservation and is cooled to 40-60 DEG C and starts to weld, and reheats lower than this temperature, purpose
Guarantee that cone roller 1 is heated axis not bending deformation, rotary electric machine 11 drives cone roller 1 to rotate together before welding, and the heating of heater 4 rises
Temperature；Welding finishes, and starting motor 11, the control of 4 temperature of heater are cooling after being kept for 8 hours at 700-750 DEG C, during normalizing,
When temperature controller shows 80 DEG C, unlatching 10 hours 9 duration of water pump prevent 1 bending deformation of cone roller, 1 double-metal layer thickness of cone roller
For 12-16mm, have the characteristics that heat-resistant antifriction, is processed between extra bus of making a connection later.Attached drawing 1 be weldering before, weldering in heat and postwelding
Normalizing procedure, attached drawing 2 are cone roller schematic diagrames after welding processing.
Above-described embodiment is only intended to citing and explanation of the invention, and is not intended to limit the invention to described
In scope of embodiments.Furthermore it will be appreciated by persons skilled in the art that the present invention is not limited to the above embodiment, according to this hair
Bright introduction can also make more kinds of variants and modifications, these variants and modifications all fall within present invention model claimed
In enclosing.
