Abstract
The utility model relates to equipment for metal heat treatment, in particular to a drum-type quenching machine. The quenching machine comprises a machine frame and a tumbling cylinder, wherein a bracket matched with the tumbling cylinder is fixed on the machine frame; the feed opening of the tumbling cylinder is connected with a power device through a transmission device; at least one group of helical blades are fixed on the inner wall of the tumbling cylinder, which can make steel balls automatically separate from one another after entering into the tumbling cylinder and only move forward among the helical blades under the driving of the blades, so as to prolong the quenching time of the steel balls; the width of the blades of the helical blades is increased gradually from the feed opening end of the tumbling cylinder to the discharge opening end thereof, so that high enough cold water can be stored in the tumbling cylinder, and a small deviation between the core hardness and the surface hardness of the steel balls is guaranteed after the steel balls are quenched, which prolongs the service life of the steel balls; and a riding wheel group is arranged on the bracket of the tumbling cylinder, and a riding wheel track is arranged on the outer side of the tumbling cylinder, so as to guarantee that the tumbling cylinder rotates reposefully during the operating process.
Description
Technical field
The utility model relates to a kind of metal heat treatmet equipment, relates in particular to a kind of drum-type quenching machine.
Background technology
In the production of steel ball, need carry out quench treatment to steel ball, purpose is to make the supercooled austenite in the steel ball carry out martensite or bainite transformation, obtains martensite or bainite structure, with the physicals of the intensity, hardness, wear resistance and the resistance to fatigue that increase substantially steel ball.In existing technology, the patent No. is 200710192045.3, and name is called the patent of " drum-type quenching machine " and has announced a kind of steel ball quench treatment equipment, can carry out multiple mode to steel ball and quench.But more fixing in some enterprise's Production Flow Charts, only adopt a kind of optimal treatment process, so this equipment can not make full use of in actual use.And the cool time of steel ball is short, and it is inhomogeneous to occur quenching hardness easily, causes the surface to produce tiny quenching crack through regular meeting.Therefore, need improve upgrading to existing technology, simplified apparatus structure, raising quenching quality also can satisfy the needs that have production status now.
Summary of the invention
The utility model is in order to overcome the defective that above-mentioned prior art exists, a kind of drum-type quenching machine is provided, it is even to make steel ball enter in the cylinder hardness after the quench treatment, after quenching is finished, steel ball can roll out quenching press voluntarily, and but the steel ball continuous batch enters in the cylinder quenching press, carries out continuous quenching and handles.
The utility model is achieved through the following technical solutions: a kind of drum-type quenching machine, it comprises frame and cylinder, be fixed with the carriage that cooperates with cylinder on the frame, the feed inlet end of cylinder is connected with power set by transmission mechanism, be fixed with at least one group of screw-blade on the inwall of described cylinder, and the width of blade of screw-blade is increased gradually by feed inlet end to the discharge port end of cylinder.
Technical characterstic of the present utility model also has: the width of described discharge port end screw-blade is three times of feed inlet end screw-blade width.
Described cylinder carriage is provided with left and right two groups of support roller groups, and the cylinder outside is provided with the support roller track that can close with the support roller assembly.
Described transmission mechanism comprises the speed reduction unit that is connected with electric motor by belt, and speed reduction unit is by the geartransmission head roll.
The feed inlet end of described cylinder is provided with follower gear, the driving toothed gear engagement on the output shaft of this follower gear and speed reduction unit.
Be fixed with four groups of screw-blades on the inwall of described cylinder.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to be fixed with at least one group of (as four groups) screw-blade on the inwall of described cylinder, and the width of blade of screw-blade is increased gradually by feed inlet end to the discharge port end of cylinder, steel ball is separated after entering cylinder automatically, and only between screw-blade, order about it and move forward, thereby reach the purpose that prolongs the steel ball cool time by blade.The width of discharge port end screw-blade is three times of feed inlet end screw-blade width, makes the cold water that can store enough height in the cylinder, and after the assurance steel ball quenched, centre hardness and surface hardness deviation were little, thereby improve the work-ing life of steel ball.The cylinder carriage is provided with left and right two groups of support roller groups, and the cylinder outside is provided with the support roller track that can close with the support roller assembly, guarantees cylinder smooth rotation in operation process.Transmission mechanism comprises the speed reduction unit that is connected with electric motor by belt, and the clutch end of speed reduction unit is provided with driving toothed gear and is meshed with the follower gear of the opening for feed end of cylinder, can make rollers roll steady, and belt transmission can be slowed down startup surge protection motor.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
