Abstract
Relating to the heat treatment processing field, the invention more specifically discloses a cam high-frequency quenching induction heating composite coil, which comprises an outer ring 1, an inner layer 2, a cooling water gap, quenching liquid inlets 5 and quenching liquid nozzles 6. Specifically, the inner layer 2 is sleeved with the outer ring 1, and they are both in a circular ring shape; the cooling water gap consists of a cooling water inlet 3 and a cooling water outlet 4 that are both in through connection with the outer ring 1; the quenching liquid inlets 5 are hollow strip cubes, and are in vertical through connection with the inner layer 2 at a certain angle; Several quenching liquid nozzles that are disposed on the side wall of the inner layer 2 inner ring. The composite coil adopting cam induction heating can save half of processing time when it is applied to high-frequency quenching on a group of (two) cams, and simultaneous heating and timely spray quenching of one or several groups of cams can be in favor of the uniformity and consistency of quenching hardness. Also, a circulating cooling layer and a quenching liquid layer work separately and have non-interference to each other. One or several groups of cams perform heating and spray quenching simultaneously, thereby saving time and ensuring the quality, also increasing the output in unit time and enhancing the efficiency.
Description
Technical field
The present invention relates to the heat treatment process field, more precisely a kind of compounding coil of cam high-frequency quenching induction heating.
Background technology
The main body of camshaft is a cylindrical barred body identical with cylinder unit length.Upper surface cover has several cams, for driving valve.The effect of camshaft is to control the action of the opening and closing of valve, in Otto cycle engine, the rotating speed of camshaft is very high, and need to bear very large moment of torsion, therefore very high in the requirement aspect intensity and support to camshaft in design, its material is generally Special Casting Iron, and the employing forging is also arranged once in a while.For meeting the requirement that cam face is wear-resisting, 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, so the cam induction heating is usually adopted, imitative type coil is single that cam is carried out to induction quenching, its shortcoming is one group or several groups of cams heating quenching one by one, and between working efficiency lower and one group or several groups of cams, can there be deviation in surface hardness and quench-hardened case.Because quenching technology has adopted instant spray quenching principle, want to ensure the quality of products and just raise the efficiency and must set about considering from heater coil.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of compounding coil of cam induction heating is provided.
The present invention 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, on internal layer, and is circular; Described cooling nozzle is divided into entrance of cooling water and cooling water outlet, all with outer ring 1, connects and is connected; Described hardening liquid import is hollow rectangular side's body, with internal layer, vertically connects and is connected at an angle; Described hardening liquid spout has several, is placed on the sidewall of internal layer inner ring.
Described outer ring is the circulating cooling layer, and when cooling, water coolant enters the cooling water outlet discharge in ，Cong outer ring, outer ring from the coolant intake of outer ring, completes hydronic task.
Described internal layer is that hardening liquid sprays layer, and during quenching, hardening liquid enters internal layer with the hardening liquid import, and the hardening liquid nozzle from internal layer inner ring sidewall is sprayed onto on workpiece in time, completes the task of spray quenching.
Described hardening liquid import can be a plurality of, are preferably two.
The endoporus of described internal layer is for packing workpiece into.
The compounding coil of described cam induction heating can be used in coaxial a plurality of stacks.
Beneficial effect of the present invention is: the compounding coil that uses the cam induction heating, not only one group of (two) cam is carried out to 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 output increased in the unit time has improved efficiency.
