[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see Figures 1-7 This utility model discloses a high-safety rapid quenching equipment for automotive brake springs, including a quenching table 1 and an electrical box 2 mounted on the quenching table 1, as well as a high-frequency heating component 3, a protective component 4, a quenching fluid circulation component 5, a cooling and filtering component 6, and a lifting component 7, wherein:

[0027] The quenching table 1 is equipped with a quenching tank 11, and an ultrasonic vibrator 12 is fixed to the inner wall of the quenching tank 11 by screws.

[0028] Please refer to the appendix. Figure 3 The high-frequency heating component 3 includes a high-frequency power supply 31, and an induction coil 33 is provided on one side of the high-frequency power supply 31. The protective component 4 includes symmetrically arranged protective plates 41, and a number of protective rods 42 are provided between the protective plates 41. A laser beam sensor 43 is fixed to the inner wall of the protective plate 41 by screws. Specifically, the high-frequency power supply 31 generates an electromagnetic field around the induction coil 33, and when the spring enters, it will generate current to achieve spring heating.

[0029] Please refer to the appendix. Figure 6The quenching fluid circulation assembly 5 includes a delivery pump 51, one end of which is connected to the quenching tank 11 and the other end is connected to the fluid exchange box 52. The cooling and filtration assembly 6 includes a filter box 61, and a cooler 62 is provided on one side of the filter box 61. The cooler 62 is connected to the fluid exchange box 52. Specifically, the filter box 61 filters out impurities generated during the quenching process to improve the quality of the quenching fluid. The cooler 62 cools the circulating high-temperature quenching fluid and allows it to enter the fluid exchange box 52. The delivery pump 51 draws low-temperature quenching fluid and continuously supplies it to the quenching tank 11.

[0030] The induction coil 33 is welded to one end of the power supply rod 32, which is fixed to the high-frequency power supply 31 by bolts. The high-frequency power supply 31 is electrically connected to the electrical box 2, and a braking spring 8 is provided above the induction coil 33.

[0031] In this embodiment, the protective plate 41 and the protective rod 42 can protect the operator from accidentally entering the high-temperature area. At the same time, the laser beam sensor 43 installed at the spring entrance can monitor the entry of foreign objects in real time. When the operator's body part enters and causes the sensor to be blocked, the buzzer alarm 45 will immediately sound an alarm. At the same time, the servo motor 71 and the high-frequency power supply 31 will be turned off to prevent the operator from being injured. Example 2

[0032] Based on the above embodiment 1, please refer to the appendix. Figure 5 as well as Figure 7 The top plate 44 is welded to the upper end of the protective plate 41. A buzzer alarm 45 is installed on the top plate 44. A liquid outlet pipe 13 is provided on one side of the quenching tank 11. The laser beam sensor 43 is electrically connected to the electrical box 2. Specifically, the liquid outlet pipe 13 can release the waste liquid in the quenching tank 11 for replacement.

[0033] The delivery pump 51 is fixed to the support platform 53 by bolts. The filter box 61 is equipped with a fine filter screen 611. One side of the fine filter screen 611 is connected to the pipe 63 through a flange. Specifically, the fine filter screen 611 can continuously filter out impurities in the quenching liquid during circulation. The impurities form a precipitate in the filter box 61 for subsequent removal, ensuring the cleanliness of the quenching process.

[0034] The cooler 62 includes a cooling rack 621, inside which are a number of cooling pipes 622. A fan 623 is provided above the cooling pipes 622. The cooling pipes 622 are connected to the liquid exchange box 52. Specifically, the large number of cooling pipes 622 increases the cooling surface area of ​​the extract liquid. Combined with the heat dissipation of the fan 623 above, the cooling effect is good and rapid cooling is achieved.

[0035] The lifting assembly 7 includes a servo motor 71, which is electrically connected to the electrical box 2. The servo motor 71 is equipped with a spiral shaft 72, which passes through the lifting plate 73 and rotates in a spiral manner.

[0036] One end of the lifting plate 73 is connected to the sliding sleeve 74, which is fitted with the sliding shaft 75 and slides. The lifting plate 73 is welded to the back plate 76, and the back plate 76 is fixed with collars 77 at the top and bottom. The collars 77 connect the two ends of the brake spring 8. Specifically, the sliding sleeve 74, together with the sliding shaft 75, limits the running trajectory of the lifting plate 73 and provides lateral support for the lifting plate 73.

[0037] In this embodiment, the servo motor 71 drives the spiral shaft 72 to rotate. The spiral shaft 72 interacts with the lifting plate 73, and the lifting plate 73 is raised and lowered by the spiral force, thereby precisely controlling the heating and quenching time of the brake spring 8 fixed on the back plate 76 and improving the quenching quality.

[0038] The working principle and usage process of this utility model are as follows: First, the brake spring 8 is hung between the upper and lower sleeves 77. The high-frequency power supply 31 is controlled by the power controller inside the electrical box 2 to generate a high-frequency current. The high-frequency current is passed into the induction coil 33 through the power rod 32, and a high-frequency alternating magnetic field is generated around the induction coil 33.

[0039] Subsequently, the electrical box 2 controls the servo motor 71 to drive the spiral shaft 72 to rotate. The spiral shaft 72 interacts with the lifting plate 73, and the spiral force drives the lifting plate 73 to descend, which in turn drives the brake spring 8 fixed on the back plate 76 to descend and pass through the induction coil. At this time, a uniform induced current is generated on the brake spring 8 to achieve uniform heating. At this time, the brake spring 8 is in a high temperature state. The protective plate 41 and the protective rod 42 can protect the operator from accidentally entering the high temperature area. At the same time, the laser beam sensor 43 installed at the spring entrance can monitor the accidental entry of foreign objects in real time. When the operator's body part enters and causes the sensor to be blocked, the buzzer alarm 45 will immediately sound an alarm. At the same time, the servo motor 71 and the high frequency power supply 31 will be turned off to prevent the operator from being injured.

[0040] After the spring is heated, the high-frequency power supply 31 is turned off, and the braking spring 8 is driven to continue to descend until it is immersed in the quenching liquid in the quenching tank 11. During the quenching process, the ultrasonic vibrator 12 installed in the quenching tank 11 causes the quenching liquid to vibrate, thereby improving the uniformity of quenching.

[0041] During quenching, the transfer pump 51 and the fan 623 are started. The transfer pump 51 circulates and exchanges the cooling quenching liquid in the liquid exchange box 52 with the heating quenching liquid in the quenching tank 11, thereby improving the quenching efficiency of the spring and enabling the equipment to operate continuously.
