Abstract
The utility model relates to a longitudinal current induction heater capable of changing current directions, which is characterized by adopting an annular main body made of copper tube; a plurality of U-shaped bending parts are made at the periphery at the upper part of the annular main body; and a plurality of water spraying small holes are formed in the inner ring of the annular main body. The longitudinal current induction heater has the advantages that the structure is compact; the operation is convenient; the adjusting is simple; the cost is low; the performance is excellent; the use is safe and reliable; and the service life of a quenching workpiece can be prolonged by effectively improving the thickness and the abrasion resistance of a hardening layer at the root of a step. The longitudinal current induction heater can be efficient, energy-saving and environment-friendly induction heating processing equipment for novel quenching process of parts in the machine building industry, and has a far-reaching impact on improving the market competitiveness of products.
Description
Technical field
The utility model belongs to the heat treatment process technical field, particularly relates to a kind of longitudinal current induction heating device that changes the sense of current.
Background technology
At present, some axial workpiece with the level needs the quenching strengthening except that outer round surface and step platform, also needs certain thickness quench-hardened case at the step root, so that improve the intensity and the fastness to rubbing at this place.The traditional induction quenching technology of this type of part is to utilize electric current of intermediate frequency to pass through individual pen or two circle ring sensor, produces inductive current (being commonly called as eddy current) in the opposite direction at workpiece surface.Because the iron resistance of workpiece heats workpiece surface rapidly, when reaching quenching temperature, the hoisting appliance of quenching machine makes workpiece to being lowered into hardening liquid or hydrojet circle, and workpiece surface is cooled off rapidly, reaches the purpose of quenching strengthening.The inductive current that the ring-type inductor block that uses at present produces in workpiece is made circumference around axis and is flowed and since inductor block can not be infinitely near the step root of axial workpiece.Because dough nut effect and proximity effect; Only on workpiece outside surface and step platform, produce inductive current; And minimum at step root inductive current, so the step root is difficult to reach the purpose of quenching strengthening, so cause depth of hardening zone can't reach >=technical requirements of 2 mm.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of with low cost, can effectively reduce and produce power consumption, increase substantially the longitudinal current induction heating device of the change sense of current of intensity and the fastness to rubbing of axial workpiece step root quench-hardened case.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Change the longitudinal current induction heater of the sense of current; It is characterized in that: this induction heater adopts copper tube to process the annular main body; Be shaped on a plurality of bending parts that take the shape of the letter U on the circumference on said annular main body top, be shaped on a plurality of water spray apertures on the said annular main body inner ring.
The utility model can also adopt following technical scheme:
The diameter of said copper tube is 16-20mm.
The diameter of said water spray aperture is 2.5-3.5mm.
Advantage and the positively effect that the utlity model has are: owing to adopted the utility model brand-new technology scheme, compared with prior art, this longitudinal current induction heating device has compact construction; Easy to operate, adjustment is simple, and is with low cost; Excellent property; Safe and reliable, can effectively improve step root quench-hardened case thickness and fastness to rubbing, improve advantages such as quenching workpiece life-span.This device can be the novel quenching technology of machinery manufacturing industry component and provides reliable and possess induction heating technology equipment efficient, energy-saving and environmental protection, and will produce far-reaching influence to improving product market competitiveness.

Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1-Fig. 3, change the longitudinal current induction heater of the sense of current, this induction heater adopts copper tube to process annular main body 1, and in the present embodiment, the diameter of said copper tube is 16-20mm.Be shaped on a plurality of bending parts that take the shape of the letter U 2 on the circumference on said annular main body top, be shaped on the water spray aperture 3 of a plurality of spray quenchings when being used to heat on the said annular main body inner ring, the diameter of said water spray aperture is 2.5-3.5mm.In the present embodiment, the diameter of said water spray aperture is preferably 3mm.
The principle of work of the utility model is:
See also Fig. 4 and Fig. 5, the longitudinal current induction heater is connected with the intermediate frequency power supply X-former, workpiece 4 is put into the longitudinal current induction heater heat; Workpiece rotates in the longitudinal current induction heater; Make the workpiece homogeneous heating, water spray cools off then, reaches the purpose of quenching.The principal character of longitudinal current induction heater is: the inductive current that in workpiece, produces parallels to the axis; Current downflow on the work; Force inductive current must pass through the step root, thereby this place is heated effectively, the depth of hardening zone at this place has reached >=technical requirements of 2 mm after the quenching.Because the workpiece heating was complementary with the Cooling Quenching time, significantly reduce the production of units power consumption, stabilized product quality is enhanced productivity.
