Abstract
The utility model discloses a key slot slender shaft quenching sensor, which comprises an insulation washer, an insulating plate, a quenching water box, an active wire and transition wires, wherein the upper portion of the insulation washer is provided with the active wire and the transition wires, and the lower portion of the insulation washer is provided with the quenching water box, the active wire and the transition wires are connected, cooling water channels are respectively arranged in the active wire and the transition wires, the insulating plate is arranged between the transition wires, and the upper end and the lower end of the active wire are semi-loop wires, and two branch wires are connected in the middle of the active wire. A quenching sensor which can evenly heat up is provided, aiming to solve the problem existing in a current annulus quenching sensor of taper angle effect when quenches shafts with key slots, thereby effectively reducing the taper angle effect. The utility model has the advantages of effectively avoiding annulus effect, evenly heating up shafts with key slots, non super-burning or cracking on the key slots, and guaranteeing quench quality of work pieces.
Description
Technical field
The utility model relates to a kind of inductor block, particularly a kind of quenching inducer.
Background technology
When at present cylindrical products such as axle class being carried out intermediate frequency or high-frequency quenching heat treatment process, generally all adopt the quenching inducer of annular, the quenching inducer of annular has the advantage of even heating, can guarantee axis body appearance homogeneous heating.But also exist deficiency, such as, when the axis body that has keyway being carried out quench treatment with the quenching inducer of annular, on the one hand, because the annulus inductor block has ring-around, causes the workpiece heat-up rate too fast, can't obtain equally distributed quenched case, on the other hand, sharp angle effect can appear in the keyway place, produces burning even crackle, in addition, workpiece deformation is also uncontrollable, can't guarantee to guarantee the quenching quality of workpiece.
Technical disadvantages for the quenching inducer that overcomes above-mentioned annular is necessary to develop a kind of new quenching inducer, can even heating, effectively avoid sharp angle effect.
Summary of the invention
Technical problem to be solved in the utility model is, is prone to the problem of sharp angle effect when at existing annular quenching inducer the axle class that keyway is arranged being carried out quench treatment, and a kind of quenching inducer that can even heating is provided, and effectively reduces sharp angle effect.
In order to solve the problems of the technologies described above, the utility model provides following technical proposal:
A kind of keyway slender axles quenching inducer, comprise insulating washer, insulcrete, quench water box, active wires and transition lead, the top of insulating washer is provided with active wires and transition lead, a quench water box is established in the below of insulating washer, active wires is connected with the transition lead, and establishes cooling-water duct in active wires and transition lead, is provided with an insulcrete between the transition lead, the two ends up and down of active wires are a semicircular ring lead, two support body leads of middle connection.Because the active wires upper and lower ends is the semicircular ring lead, thereby avoids occurring ring-around, makes that the keyway place on the workpiece can thermally equivalent.
Quench in order to ensure the middle part to thin axle, described support body lead is vertical with the semicircular ring lead.The centre of alignment pieces just in time, the quenching position of inductor block can make the workpiece thermally equivalent like this, avoids producing burning and crackle.
The both sides of described quench water box respectively are provided with a water inlet pipe, and are provided with several spout holes in quench water box inboard.Current in the quench water box spray from spout hole, and workpiece is cooled off.
The beneficial effects of the utility model are presented as:
One, active wires is made up of three parts, and upper and lower ends is the semicircular ring inductor block, and the centre is the support body lead, effectively avoids occurring ring-around, can be to the axle even heating of band keyway;
Two, can not produce keyway place heat and cross and focus mostly on, can not produce burning of keyway place or crackle, guarantee workpiece quenching quality;
Three, simple and reasonable, easy to use.

Embodiment
Below in conjunction with Fig. 1 and Fig. 2 the utility model is described in further detail:
A kind of keyway slender axles quenching inducer, comprise insulating washer 1, insulcrete 2, quench water box 5, active wires 3 and transition lead 4, the top of insulating washer 1 is provided with active wires 3 and transition lead 4, a quench water box 5 is established in the below of insulating washer 1, active wires 3 is connected with transition lead 4, and in active wires 3 and transition lead 4, establish cooling-water duct 6, be provided with an insulcrete 2 between the transition lead 4, the two ends up and down of active wires 3 are a semicircular ring lead 31,33, two support body leads 32 of middle connection.Because active wires 3 upper and lower ends all are semicircular ring lead 31,33, avoid occurring ring-around, make that the keyway place on the workpiece can thermally equivalent.
Quench in order to ensure the middle part to thin axle, described support body lead 32 is vertical with semicircular ring lead 31,33.The centre of alignment pieces just in time, the quenching position of inductor block can make the workpiece thermally equivalent like this, avoids producing burning and crackle.
The both sides of described quench water box 5 respectively are provided with a water inlet pipe 7,8, and are provided with several spout hole (not shown) in quench water box 5 inboards.Current in the quench water box 5 spray from spout hole, and workpiece is cooled off.
