Description
Technical Field
The invention relates to an induction heat treatment device, in particular to an induction heat treatment device for pawl parts, which is used for carrying out induction heat treatment on pawls of pawl parts.
Background
To improve the wear resistance and fatigue resistance of metal parts, nitriding heat treatment is generally performed. Nitriding heat treatment is a heat treatment technique that allows nitrogen atoms to permeate into the surface layer of a metal part at a certain temperature, and can form a hardened layer on the surface of the metal part. However, with the increase of metal part types and the change of processing requirements, compared with other new technologies, the existing nitriding heat treatment has the problems of high processing cost, long processing period and low production efficiency.
The induction heat treatment is a heat treatment technology for improving the local strength of the metal part by utilizing induction current to locally and rapidly heat and cool the metal part, can also improve the strength of the metal part, forms a hardening layer on the surface of the metal part, and can replace nitriding heat treatment to process the metal part. The working principle is as follows: placing the metal part into a working area of an inductor, and introducing alternating current with a certain frequency into the inductor to generate an alternating magnetic field, so that induced current is generated in the metal part, and the surface temperature of the metal part is increased; and then rapidly cooling the metal part, and generating a hardening layer on the surface of the metal part, namely realizing surface quenching. Compared with nitriding heat treatment, the induction heat treatment has the advantages of high processing speed, easy control of a hardening layer, small environmental pollution and the like, and is widely applied to surface quenching of metal parts. However, the existing scheme can not meet the processing requirements of some metal parts, such as pawl parts.
The pawl parts are generally designed as a revolving body, and the pawls are of special-shaped structures and distributed along the circumference according to a certain proportion. Fig. 1 is a schematic structural view of a conventional pawl-like part including a rotator (003), six pin holes (002) provided on the rotator (003), and nine pawls (001) provided on the outer periphery of the rotator (003). In order to improve the strength and the wear resistance of the pawl parts, the outer surface of the pawl (001), particularly the two side areas, need to be quenched, and the processing requirements are as follows: the surface hardness is HRC53 or more, and the depth of the hardening layer is not less than 0.5mm.
Because the pawl (001) has a complex structure and a thin wall, the width of the pawl (001) is 22mm, the thickness of the pawl is only 2.5mm, and when the conventional induction heat treatment device is used for processing, the technical problems that the pawl (001) is quenched and the quenching area appears on the adjacent vertical surface to cause the brittleness increase of parts, the processing effects among a plurality of pawls (001) are inconsistent, the pawl (001) is easy to overheat and deform or even melt, and the pin hole (002) is easy to be heated and deformed exist.
From the above, it is clear that for the easily quenched parts such as thin-walled pawls or similar parts with spline ends less than 2.5mm from the reducing end face, the existing induction heat treatment device cannot basically meet the processing requirements.
For realizing that the induction heat treatment processing effect of each part of part is unanimous, chinese patent publication No. CN202164328U discloses an annular track integral quenching device, including liquid sprayer, track inductor, the liquid sprayer is a torus, is hollow cavity in the torus, is connected with feed liquor joint and connecting screw on the liquid sprayer, and track inductor installs in the inner circle cavity of liquid sprayer, its characterized in that: the inner ring of the liquid spraying device is provided with liquid spraying holes on the circumference of 360 degrees; the track inductor comprises at least 5 track induction coils evenly arranged along the circumference, at least 5 track induction coils are installed on a fixed block, the fixed block is fixed on the liquid sprayer through bolts, the track induction coils are mutually communicated, one end is provided with a liquid inlet, the other end is provided with a liquid outlet, and a public polar plate is installed on the fixed block and connected with the track induction coils. However, the scheme is limited to quenching annular track parts, and other problems of pawl part quenching cannot be solved.
For realizing that the pawl hardness is even after induction heat treatment, chinese patent publication No. CN211689148U discloses a thin sheet type car parking gear box pawl quenching frock, including installing the quenching inductor in the quenching lathe frame, the quenching inductor includes connecting plate and heating wire, the connecting plate parallel interval is provided with two, the both ends of heating wire are fixed with two connecting plates respectively, its characterized in that, the heating wire includes two sections parallel interval setting's heating section, two be formed with the heating gap between the heating section, and two the heating section all sets up along pawl tooth profile trend. But the frock structure that this scheme provided is comparatively complicated, and different pawls must customize the frock that has different spare parts, and can't solve the inconsistent problem of processing effect between a plurality of pawls.
