The main body of camshaft is a cylindrical barred body identical with cylinder unit length.Upper surface cover has several cams, is used for driving valve.The effect of camshaft is the opening and closing action of control valve, the rotating speed of camshaft is very high in Otto cycle engine, and need to bear very large moment of torsion, and is therefore very high in the requirement aspect intensity and the support to camshaft in the design, its material generally is Special Casting Iron, and the employing forging is also arranged once in a while.For satisfying the wear-resisting requirement of cam face, producing camshaft both at home and abroad mainly partly adopts high-frequency quenching to make it to form the technique of Malpighian layer to nose, be egg shape because cam face is irregular, for guaranteeing the homogeneity of its surface hardness and quench-hardened case, imitative type coil is single that cam is carried out induction quenching so the cam induction heating usually adopted, its shortcoming is one by one heating quenching of a group or several groups of cams, and can there be deviation in surface hardness and quench-hardened case between working efficiency lower and one group or several groups of cams.Because quenching technology has adopted instant spray quenching principle, want to ensure the quality of products and just raise the efficiency and to set about considering from heater coil.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of compounding coil of cam induction heating is provided.
The utility model is for achieving the above object, adopt following technical proposals to realize: a kind of compounding coil of cam induction heating, it comprises outer ring, internal layer, cooling nozzle, hardening liquid import and hardening liquid spout, wherein, described outer ring sleeve and is circular on internal layer; Described cooling nozzle is divided into entrance of cooling water and cooling water outlet, all connects with outer ring 1 to be connected; Described hardening liquid import is hollow rectangular side's body, vertically connects at an angle with internal layer to be connected; Described hardening liquid spout has several, places on the sidewall of internal layer inner ring.
Described outer ring is the circulating cooling layer, and water coolant enters the outer ring from the coolant intake of outer ring during cooling, discharges from outer ring cooling water outlet, finishes hydronic task.
Described internal layer is that hardening liquid sprays layer, and hardening liquid enters internal layer with the hardening liquid import during quenching, and the hardening liquid nozzle from internal layer inner ring sidewall in time is sprayed onto on the workpiece, finishes the task of spray quenching.
Described hardening liquid import can be a plurality of, are preferably two.
The endoporus of described internal layer is used for packing into workpiece.
The compounding coil of described cam induction heating can use in coaxial a plurality of stacks.
The beneficial effects of the utility model are: the compounding coil that uses the cam induction heating, not only one group of (two) cam is carried out high-frequency quenching and can save half process period on year-on-year basis, and one group or several groups of cams heat homogeneity and the consistence that timely spray quenching is conducive to quenching hardness simultaneously, and circulating cooling layer and the quenching liquid layer mutually noninterfere of separately working, one group and several groups of cams heat simultaneously and spray quenching, not only saved man-hour but also guaranteed quality, the efficient that increased output increased in the unit time.
