Description
Technical field
The present invention relates to sprocket wheel manufacture field more particularly to a kind of high-frequency induction devices for sprocket wheel quenching.
Background technology
Sprocket wheel refers to the wheel with cog type whelp, mutually to be nibbled with the accurate block of pitch on pitch chain ring or cable
It closes, currently, sprocket wheel is widely used in the machine driving of the industries such as chemical industry, textile machine, food processing, instrument, oil
Deng.
At work under the action of stress alternations, the impact load such as being reversed and being bent, its superficial layer is born sprocket wheel
Stress more higher than center portion, in the occasion to be rubbed, superficial layer is also constantly worn, therefore is carried to some piece surface layers
Going out the requirements such as high intensity, high rigidity, high-wearing feature and high fatigue limit, only surface peening could meet above-mentioned requirements, due to
Surface hardening have many advantages, such as deformation it is small, productivity is high, therefore in production apply it is extremely wide, sprocket wheel quench purpose be to make
Cold austenite carries out martensite or bainite transformation, obtains martensite or bainite structure, then coordinates returning with different temperatures
Fire, with intensity, hardness, wearability, fatigue strength and the toughness etc. for greatly improving steel, to meet various machine components and work
The different requirements of tool.
High-frequency inductor is that sprocket wheel carries out quenching common device, currently, conventional high-frequency inductor is carried out to sprocket wheel
When quenching, sprocket wheel can not be quickly cooled down after the completion of quenching, therefore, quenching effect is not ideal enough.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of high-frequency induction device for sprocket wheel quenching, background is effectively solved
The problem of being pointed out in technology.
The technical solution adopted by the present invention is：
A kind of high-frequency induction device for sprocket wheel quenching, including a pair of of connecting plate, a pair of of collecting pipe and a coil,
Collecting pipe described in a pair is respectively equipped with the first water inlet pipe and the first outlet pipe in the one end to connect with connecting plate, and described first
Water inlet pipe, collecting pipe, coil and the first outlet pipe are connected, and a quenching cooling tube, institute are fixed on the inside of the coil
It states and is densely covered with multiple hole for water sprayings on the inside of quenching cooling tube, the top of the quenching cooling tube is equipped with multiple second water inlet pipes, institute
The second water inlet pipe stated extends towards the external of quenching cooling tube in the horizontal direction.
Enter from the first water inlet pipe, fast quickly cooling is carried out to collecting pipe and coil by the coolant liquid of the first outlet pipe discharge
But, the quenching liquid enter from the second water inlet pipe, sprayed by hole for water spraying is quickly cooled down sprocket wheel, and multiple second water inlet pipes are set
It sets, increases into the quenching flow quantity in quenching cooling tube, to which the quenching liquid speed of hole for water spraying ejection is fast, cooling effect
It is good.
Preferably, the collecting pipe, coil and quenching cooling tube are red copper square tube, the quenching cooling tube
Thickness is more than the thickness of coil.
The cooling tube thickness of quenching is larger, can open up more hole for water sprayings, promotes cooling effect.
Preferably, the coolant liquid that first water inlet pipe is passed through, successively by be connected with the first water inlet pipe collecting pipe,
Then coil, the collecting pipe being connected with the first outlet pipe are flowed out from the first outlet pipe, the quenching liquid in the quenching cooling tube
Enter from the second water inlet pipe, is sprayed by hole for water spraying.
Preferably, first water inlet pipe and the first outlet pipe is perpendicular with collecting pipe, the connecting plate with
On the same line, second water inlet pipe is three to collecting pipe, is distributed on quenching cooling tube.
The present invention coordinates quenching machine to use, and when in use, can accelerate the quenched cooling velocity of sprocket wheel, promote quenching
Effect.
