The pin rail in past adopts whole modifier treatment technology, the hardness basically identical on its core and surface.Can not satisfy pin rail profile of tooth should have high supporting capacity and wear resistance, but also the performance requriements of certain impact resistance will be arranged.At present, the profile of tooth of pin rail all adopts the monodentate induction quenching, though pin rail toothed section performance is increased, because the inductor block output rating is low, heat-up time is long, makes that the workpiece surface oxidation is serious, the workpiece surface quality after the moulding is coarse.The inductor block own loss is big, and shorten work-ing life greatly, and productivity is low, cost is high, labor strength is big.
Summary of the invention
The purpose of this utility model provides a kind of pin rail bidentate induction hardening equipment, to overcome the problems referred to above of the prior art.
The technical scheme that the utility model adopted is: pin rail bidentate induction hardening equipment is made up of gusset plate, ruhmkorff coil, water-cooled tube and magnetizer, also is made of aqueduct, plate, preset pieces, cooling water cavity, water-jet and bolt etc.; The surface shape of adjacent two profiles of tooth of ruhmkorff coil imitative pin rail, gusset plate is welded on the top of ruhmkorff coil, and two water-cooled tubes are welded on vertical two outsides of ruhmkorff coil respectively; Preset pieces is fixed by welding on the ruhmkorff coil, and magnetizer is embedded on the ruhmkorff coil, between two preset piecess; Plate is fixed by welding in two outsides of ruhmkorff coil lower end, and two cooling water cavities are respectively by being bolted in the plate; Three aqueducts are arranged, and middle aqueduct is welded on the mid-way of ruhmkorff coil lower end, keeps 2 mm clearance with magnetizer; The two ends aqueduct respectively is welded on cooling water cavity top, is positioned at the outside of ruhmkorff coil lower end, and three aqueducts and all are communicated with two water-cooled tubes 3 on same sea line; Water-jet is by being welded to connect below middle aqueduct; Cooling water cavity is being evenly distributed with spout hole near the ruhmkorff coil side, and the water-jet both sides are evenly distributed with spout hole.
Cooling water cavity is welded by 2 millimeters copper coins, and at the spout hole that is uniform-distribution with 2 millimeters of Φ near the ruhmkorff coil side, pitch-row is 6 millimeters.
Water-jet is welded by 2 millimeters copper coins, is uniform-distribution with the spout hole of 2 millimeters of Φ in its both sides, and pitch-row is 6 millimeters.
The beneficial effects of the utility model are, the induction installation compact construction, and the output rating height, heat-up time is short, and increase work-ing life, and under the impaired situation of induction installation, repair simple, convenient.Pin rail toothed section quenching hardness is uniform and stable, and moulding rear surface quality is good.The production efficiency height, easy to operate, economic and practical, reduce working strength of workers greatly.
