Description

TECHNICAL FIELD

[0001] The utility model relates to a heat treatment equipment, in particular to a kind of heat treatment equipment for flywheel applied to heat treatment equipment field. BACKGROUND

[0002] Induction heating is based on the principle of electromagnetic induction. When alternating current passes through the induction coil, an alternating magnetic field is generated. The bicycle flywheel is placed in the magnetic field, and due to electromagnetic induction, eddy currents are generated inside the flywheel. According to Joule's law, these induced currents generate heat inside the flywheel, thereby achieving heating. For example, high-frequency induction heating equipment can heat the flywheel locally or as a whole to quench temperature in a short time.

[0003] Chinese patent CN221626315U specification discloses a quenching machine, comprising: a quenching machine housing, a working chamber, an inner cavity provided in the quenching machine housing, a first gear driven to rotate by a second gear, thereby driving the first and second racks to rotate, the first and second racks driving the mounting plate to rotate when rotating, and the limiting clamp clamping the two sides of the part, so that the upper surface of the part is not blocked, the device can fully quench the part, and the quenching quality of the device for the part is improved.

[0004] During the gear quenching process, the inner wall of the cooling pool needs to be cleaned regularly, because during the quenching process, the oxide skin on the surface of the gear, oil stains and impurities generated by the quenching medium after long-term use will gradually deposit on the inner wall of the cooling pool. When a large amount of metal oxide skin and other impurities are mixed, it will affect the cooling speed of the quenching medium. The manual cleaning of the attachments on the inner wall of the pool is time-consuming, labor-intensive and inefficient, so a heat treatment equipment for flywheel with inner wall pretreatment function is needed to make the subsequent manual cleaning of the residues in the pool more labor-saving. SUMMARY

[0005] In view of the above prior art, the technical problem to be solved by the utility model is that during the quenching process, the oxide skin on the surface of the gear, oil stains and impurities generated by the quenching medium after long-term use will gradually deposit on the inner wall of the cooling pool. When a large amount of metal oxide skin and other impurities are mixed, it will affect the cooling speed of the quenching medium. The manual cleaning of the attachments on the inner wall of the pool is time-consuming, labor-intensive and inefficient.

[0006] The utility model provides a kind of heat treatment equipment for flywheel, including cooling treatment pool, the lower inner wall of cooling treatment pool is rotatably connected with vertical rotating rod, the upper end of vertical rotating rod is fixedly connected with transverse outer pole in four corners, the end of multiple transverse outer pole away from vertical rotating rod is fixedly connected with servo indexing turntable, multiple clamps are installed in the upper end of servo indexing turntable, the upper end of cooling treatment pool is fixedly connected with first diameter heat treatment electromagnetic induction ring, the outer end of vertical rotating rod is fixedly connected with external connecting ring sleeve, the end of external connecting ring sleeve away from vertical rotating rod is fixedly connected with L type inner wall scraping rod, the end of L type inner wall scraping rod close to the inner wall of cooling treatment pool is provided with recess vertical mouth, the inner wall of recess vertical mouth is fixedly connected with elastic abutting column, the elastic abutting column is fixedly connected with scraping wall inner block away from L type inner wall scraping rod, the outer end of scraping wall inner block is fixedly connected with metal friction net, and metal friction net and the inner wall of cooling treatment pool are mutually contacted.

[0007] In the above-mentioned heat treatment equipment for flywheel, the L-shaped inner wall scraping rod provided outside the servo indexing turntable during the self-rotation process of the vertical rotating rod can maximize the timely removal of the adherents on the inner wall of the cooling treatment pool, making the subsequent manual cleaning of the residual materials in the pool more labor-saving and efficient.

[0008] As a further improvement of the present application, the horizontal upper end of the L-shaped inner wall scraping rod is fixedly connected with a triangular weighing inclined plane rod, which is connected with the external connecting ring sleeve.

[0009] As a further improvement of the present application, the multiple clamps are arranged in a ring shape at equal distances, and the outer side of the clamp holds the flywheel body to be processed.

[0010] As a further improvement of the present application, the first diameter heat treatment electromagnetic induction ring is located directly above the flywheel body to be processed, and the flywheel body to be processed extends into the first diameter heat treatment electromagnetic induction ring.

[0011] As another improvement of the present application, two second diameter heat treatment electromagnetic induction rings are arranged on the upper end of the cooling treatment pool, and the inner end of the cooling treatment pool is filled with a plurality of cooling liquids.

[0012] As a supplement to another improvement of the present application, the two second diameter heat treatment electromagnetic induction rings and the first diameter heat treatment electromagnetic induction ring are equally distributed on the upper side of the cooling treatment pool.

[0013] As a supplement to another improvement of the present application, the diameters of the two second diameter heat treatment electromagnetic induction rings and the first diameter heat treatment electromagnetic induction ring are arranged from large to small.

[0014] In summary, the present scheme sets the L-shaped inner side wall scraper rod outside the self-rotating process of the vertical rotating rod of the servo indexing turntable. The L-shaped inner side wall scraper rod can first use the sharp corner to scrape the adherents on the inner side wall of the cooling treatment pool, and at the same time, the scraping wall inner block inside the vertical notch between the L-shaped inner side wall scraper rod and the cooling treatment pool is in contact with the inner side wall of the cooling treatment pool, so that the metal friction net outside the scraping wall inner block is in strong friction with the inner side wall of the cooling treatment pool, which can maximize the timely scraping of the adherents on the inner side wall of the cooling treatment pool. The elastic resistance column can provide pressure for the metal friction net, so that the contact effect with the inner side wall of the cooling treatment pool is better, the friction coefficient is stronger, and the heat transfer coefficient between the relatively clean inner wall of the cooling treatment pool and the quenching medium is higher. In hot working, the heat of the treated flywheel body can be absorbed faster, so that the cooling speed of the treated flywheel body is more stable and meets the process requirements of hot working, and the subsequent manual cleaning of the residual substances in the pool is more labor-saving and efficient.

[0028] Figures 1-5The present scheme shows that the plurality of flywheel bodies 5 to be processed are clamped in the corresponding clamps 4 on the servo indexing turntable 3 by the clamps 4.
