Abstract
The invention relates to a surface quenching sensor of a small-diameter internal spline. The sensor comprises an H-shaped sensor main body and further comprises a first water inlet pipe, a second water inlet pipe and a machinable magnetizer, wherein the H-shaped sensor main body is obtained by welding two copper pipes with semicircular sections by using a copper plate; the machinable magnetizer is positioned between the two copper pipes with the semicircular sections and on the copper plate; sensing conducting coils are respectively mounted on two sides of the H-shaped sensor main body; a plurality of water spraying holes are formed in the two semicircles of one end of the H-shaped sensor main body; and the sensing conducting coils are connected to a quenching transformer through the first water inlet pipe and the second water inlet pipe; and burning or cracking of the sensor, caused by the reason that large-power current passes through the sensor, can be effectively avoided, so that the quenching surface of the internal spline is heated to quenching temperature and depth at one time; and moreover, the quenching surface of the internal spline can be immediately sprayed with water and cooled so as to achieve desired hardness and depth of the quenching surface.
Description
Technical field
The present invention relates to a kind of quenching inducer, particularly a kind of minor diameter internal spline hard surfacing inductor block that can carry out to like products such as minor diameter internal splines supersonic frequency induction hardening.
Background technology
Existing internal spline quenching inducer all adopts traditional inner hole quenching inductor block production.The inductor block life-span is low, and production efficiency is low, unstable product quality, and production efficiency is low, and production cost is high.Traditional inner hole quenching inductor block quenching technology, easily make product can not reach processing requirement, this mainly is because the heating power during induction heating is little, heat-up time is long, heat after the heating is taken away by work, be difficult for to arrive quenching temperature, reach quenching temperature and can cause that again hardened depth spends dark or through hardening; Strengthen induction hardened power, can make the inductor block temperature within moment, arrive fusing point, make inductor block scorification or cracking.
And traditional minor diameter internal spline hard surfacing inductor block because the endoporus that need to quench is less, is used in very little that the required copper pipe diameter of inductor block of heating need to do, and the electric current that inductor block passes through when making like this inductor block heating can not be too large; If adopt scan-type to quench, because the endoporus space is less, the hardening liquid heating surface that easily backflows can't be implemented; If strengthen the induction quenching electric current, the inductor block temperature is raise very fast, add the cooling water flow that is used for the cooling inductor block in the copper pipe and can not form the flow that enough inductor blocks cool off because the copper pipe sectional area is little, limited the peak flow that inductor block passes through, inductor block can not get effectively cooling and burns.Because above several reasons make induction quenching can not reach hardness or the degree of depth of processing requirement.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of large power, electrically of can effectively avoiding to flow inductor block scorification or the cracking that causes by inductor block, make the internal spline hardened face once be heated to quenching temperature and the degree of depth, and the cooling of spraying water immediately reaches the minor diameter internal spline hard surfacing inductor block of required hardened face hardness and the degree of depth.
The objective of the invention is to finish by following technical solution, this inductor block welds the H shape inductor body that forms by the copper pipe of two sections semi-circular cross-section is middle with copper coin, and comprises the first water inlet pipe, the second water inlet pipe and can process magnetizer; This can be processed on the plumbers shed and copper coin that magnetizer is positioned at two sections semi-circular cross-section, and the sensor wire circle is equipped with respectively in the both sides of this H shape inductor body, is drilled with several spout holes on two semicircles of H shape inductor body one end.
As preferably, described sensor wire circle is connected on the induction hardening transformer by the first water inlet pipe, the second water inlet pipe.
As preferably, described spout hole is perpendicular to treating hardened face, and the spacing between spout hole and the spout hole is 2mm, and its diameter is 1mm.
Beneficial effect of the present invention is: the flow of inductor block water coolant is doubled, because both sides enter the cooled hardening liquid of being of inductor block, the inductor block cooling performance is improved more than the twice, faradic power in the time of so just can increasing induction heating, realized making in a short period of time part to treat that hardened face once is heated to quenching temperature and the degree of depth, the inner hole quenching induction heating technology is implemented; And, used hardening liquid to carry out sensor structure to the cooling of inductor block, make the ejection of hardening liquid perpendicular to treating hardened face, better to the cooling result of hardened face, and simplified the layout of water spray cover; Using the ultrasonic frequency induction hardening equipment to carry out induction quenching with this inductor block processes, enough electric currents are evenly distributed on the required area of internal spline, quenching rear surface measurement of hardness reaches HRC54～58, and depth of hardening zone reaches the following 0.75-2.5mm of spline tooth root.
