[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0024] Please see Figures 1-5 This utility model discloses a dual-medium quenching equipment for manufacturing automotive brake springs, including a quenching machine tool 1 and a PLC control console 2 located on one side of the quenching machine tool 1, and also includes a high-frequency heating component 3, a displacement component 4, and a dual-medium quenching component 5, wherein:

[0025] PLC control console 2 includes PLC host 21, and a programming device 22 is provided on one side of PLC host 21. Specifically, the programming device 22 can input control programs and PLC host 21 can execute control commands.

[0026] Please refer to the appendix. Figure 3 The high-frequency heating component 3 includes a power cabinet 31, which is installed on the top surface of the quenching machine tool 1. One side of the power cabinet 31 is electrically connected to an induction heater 32, and an induction coil 33 is installed on one side of the induction heater 32. A processing spring 34 is provided inside the coil of the induction coil 33. Specifically, when the power cabinet 31 is started, the induction heater 32 starts to work. The induction heater 32 passes a high-frequency current through the induction coil 33, thereby generating a high-frequency magnetic field, which causes eddy currents to be generated inside the conductor of the processing spring 34, thereby generating heat for heating.

[0027] The dual-medium quenching assembly 5 includes a quenching tank 51, which is located on the top surface of the quenching machine tool 1. A quenching pipe 52 is located directly above the quenching tank 51. One end of the quenching pipe 52 is connected to one end of a water pump 54 via a flange 53. The other end of the water pump 54 is connected to a water inlet pipe 55, which extends into the interior of the water tank 56.

[0028] The bottom of the quenching tank 51 is connected to one end of the return pipe 57, and the other end of the return pipe 57 is connected to the water tank 56. An oil tank 58 is provided on one side of the water tank 56.

[0029] In this embodiment, when the processed spring 34 reaches above the quenching tank 51, the water pump 54 is started to draw water out of the water tank 56 and spray it out from the quenching pipe 52 to cool the hot processed spring 34 for a predetermined time. Then it continues to move above the next quenching tank 51 and uses the quenching oil in the oil tank 58 to cool the processed spring 34 a second time until it is cooled down, thus completing the dual-medium quenching operation. Example 2

[0030] Based on the above embodiment 1, please refer to the appendix. Figure 4 , Figure 5 The PLC host 21 is installed on the control box 23, and the control box 23 is equipped with a servo motor 41, which is electrically connected to the PLC host 21.

[0031] The displacement assembly 4 includes a fixed side plate 42, which is installed at both ends of the quenching machine tool 1, and two support shafts 43 are symmetrically arranged between the fixed side plates 42.

[0032] The servo motor 41 is equipped with a motor shaft 44, and a friction wheel 45 is provided on the motor shaft 44. The friction wheel 45 is made of rubber and is a combination of two symmetrical flat-topped pyramids.

[0033] The friction wheel 45 is close to the transverse axis 46 and rotates in frictional engagement. One end of the transverse axis 46 is fixedly connected to the transverse plate 47, and the other end is fixedly connected to the slide plate 48. Both the slide plate 48 and the transverse plate 47 are penetrated by the support shaft 43 and slide in engagement.

[0034] The processing spring 34 is symmetrically provided with hooks 341 at both ends. The hooks 341 are movably connected to the hanging rings 35. The hanging rings 35 are fixedly connected to the turntable 36 through a straight shaft. One side of the turntable 36 is mounted on the rotating motor 37, which is fixed to one side of the transverse plate 47 by screws. The back side of the other turntable 36 is rotatably fitted into one side of the slide plate 48 through a straight shaft. Specifically, the rotating motor 37 uses the turntable 38 to drive the processing spring 34 to rotate at a uniform speed, which can ensure that the spring surface is heated evenly and cooled evenly afterward, reducing the occurrence of deformation and cracks.

[0035] In this embodiment, the servo motor 41 causes the motor shaft 44 to rotate clockwise. The friction of the friction wheel 45 on the motor shaft 44 causes the transverse axis 46 to move to the right. The transverse axis 46 uses the transverse plate 47 to drive the rotary motor 37 on it to move. The rotary motor 37 uses the turntable 36 to pull the hanging ring 35, thereby causing the machining spring 34 on the hanging ring 35 to move linearly laterally, so as to accurately control the time of the machining spring 34 in different quenching steps.

[0036] The working principle and usage process of this utility model are as follows: First, the hooks 341 at both ends of the processed spring 34 are hung in the hanging ring 35 of the equipment to form a fixed position. Then, the control program is input through the programming device 22 of the PLC console 2, the PLC host 21 executes the control command, and at the same time, the servo motor 41 and the rotary motor 37 are started.

[0037] Subsequently, the servo motor 41 causes the motor shaft 44 to rotate clockwise, and the motor shaft 44 drives the friction wheel 45 on it to rotate. Then, the friction force acts on the transverse axis 46 to move to the right. The transverse axis 46 drives the rotary motor 37 on it to move through the transverse plate 47. The rotary motor 37 pulls the hanging ring 35 through the turntable 36, thereby causing the processing spring 34 on the hanging ring 35 to move laterally in a straight line.

[0038] According to the programmed movement time, when the processing spring 34 moves into the induction coil 33, the power cabinet 31 is activated to start the induction heater 32. The induction heater 32 passes a high-frequency current through the induction coil 33, thereby generating a high-frequency magnetic field, which causes eddy currents inside the conductor of the processing spring 34, thereby generating heat for heating. At the same time, the rotating motor 37 uses the turntable 38 to drive the processing spring 34 to rotate at a uniform speed, which can ensure that the spring surface is heated evenly and then cooled evenly, reducing the occurrence of deformation and cracks. When the processing spring 34 has completely passed through the induction coil 33 and been heated, the power cabinet 31 is turned off.

[0039] The processing spring 34 then continues to run. When it reaches the top of the quenching tank 51, the water pump 54 is activated to extract water from the water tank 56 and spray it out through the quenching pipe 52 to quickly cool the hot processing spring 34. According to the set spray cooling time, the processing spring 34 is precisely cooled to between 200 and 300 degrees Celsius. Then it continues to move to the top of the next quenching tank 51, and the water pump 54 is used to extract quenching oil from the oil tank 58 to cool the processing spring 34 a second time until it is cooled down. This completes the dual-medium quenching operation, which achieves precise control of the quenching time of different media and greatly improves the production quality of brake springs.
