Technical field
The utility model relates to a kind of terminating unit that inductive heating principle heats the quenching workpiece of using, and relates to a kind of auto parts that are used for specifically, and head has the ruhmkorff coil that the spline shaft structure workpiece quenches.
Background technology
The component that have spline shaft structure are at automobile, and aviation extensively is applied in space flight and the equipment manufacture, and the part shank also has the cylinder of multistage different diameter to form except that spline.Because the different diameter of shank when carrying out induction heat treatment, causes the skewness of local current, so the hardened layer of different diameter can occur inhomogeneous, small dia place hardened-depth; Major diameter place hardened layer is shallow; In the nook of vary in diameter,, even can't obtain hardened layer because caloric receptivity is big.Generally can pass through inductor block copper pipe shape variation, and the magneticline of force distribution of the specific distribution of magnetizer change inductor block coil, make the spline axis body of different diameter obtain uniform hardened layer.
Automobile is to need to produce in enormous quantities processing with part, and mostly common inductor block is single is made up of copper pipe and siliconized plate, does not have the fixed framework; Mostly the type of cooling is one-in-and-one-out; Comparatively simple, processing is prone to cause the inductor block temperature distortion for a long time, and the processing life-span is lower.For auto parts, possibly need several thousand of processing every day, and present like this inductor block can't satisfy stable and durable requirement.
Present technological difficulties have: 1) can not obtain uniform effective case depth and hardness in the different diameter zone; 2) can't begin to obtain the transitional region of full slyness at effective hardened layer with end region; 3) the different diameter zone can crack.
The utility model content
The technical problem that the utility model will solve provides a kind of ruhmkorff coil that splined shaft quenches that is used for, to overcome the defective that exists in the prior art.
The utility model adopts following technical scheme:
A kind of ruhmkorff coil that is used for the splined shaft quenching; Comprise coil case, establish cooling line in the body that said coil case surrounds, said body upper end is connecting the contiguous block that is provided with suction culvert; Said body comprises first, second linear body of opposition; First, second linear body lower end connects first, second ring-type body initiating terminal separately respectively, the external contour circle body of said first, second loop pipe, in establish cooling line; And be on the different plane position, the terminal of first, second ring-type body all is connected with the rising pipe that is provided with outlet pipeline.
Further, the radius-of-curvature of said first, second ring-type body is different.
Further, first, second ring-type body integral body is semicircular.
Further, said first, second linear body is respectively equipped with magnetizer and sheet mica on first, second ring-type body, and the proportioning of magnetizer and sheet mica is different with proportioning on the ring-type body on the linear body.
Further, the cross-sectional shape of said linear body is a square; The cross-sectional shape of said ring-type body is a pentagon.
Further, said ruhmkorff coil is fixed through bolt, and said bolt comprises threaded rod member, bolt and first, second linear body, or first, second ring-type body connects.
Further, said contiguous block has two, and divides in the every contiguous block that is arranged and be provided with blind hole, and this blind hole is connected with the intravital cooling line of first, second linear tube.
Further, a through hole is also respectively established in the both sides of said blind hole.
Further, establish isolator between said two contiguous blocks.
Can be known that by above technical scheme water coolant gets into from the water inlet pipe of contiguous block, through the cooling line of two linear bodys, arrive the ring-type body, behind the cooling line through the ring-type body, flow out from rising pipe at last, be two to advance the mode that outes.Secondly the ring-type body is two-layer staircase structural model, can cooperate workpiece different diameter zone, the step corner on the heating splined shaft.On linear body and ring-type body, establish magnetizer and isolator, through different proportionings, change magneticline of force and distribute, solved thermal treatment zone effective case depth and the uneven problem of hardness in the workpiece like this, processing quality improves greatly.
