The electromagnet 303 is de-energized and reset under the elastic force of the spring 302, so that the separator 301 and the electromagnet 303 are adsorbed and separated, and the unloading and stopping of the workpiece are completed, so as to realize intermittent loading. A hollow chuck 4 is installed on the lower side of the quenching machine body 1, and a lifting assembly 5 is installed on the lower side of the hollow chuck 4 on the quenching machine body 1. The lifting assembly 5 includes a bracket 503 which moves back and forth along the Z axis, and a detection block 6 is installed on the bracket 503. A sensor compatible with the detection block 6 is installed on the quenching machine body 1. When the detection block 6 is detected by the sensor, the electromagnet 303 is energized to realize the adsorption and separation of the separator 301 and the electromagnet 303.

[0025] Reference Figure 1 The quenching machine body 1 includes a machine body 101, on which an induction heater 102 and a spray ring 103 are sequentially installed from top to bottom. The workpiece passes through the inner side of the induction heater 102 and the spray ring 103 in sequence, and the workpiece is heated by the induction heater 102. The spray ring 103 is supplied with water by an external cooling water circulation device, and the workpiece is sprayed by the spray ring 103.

[0026] Reference Figure 2 A loading port is provided at the lower side of the slideway 201. The axes of the induction heater 102, the spray ring 103, the hollow chuck 4 and the loading port are in a collinear line. The hollow chuck 4 cooperates with the loading port to guide the workpiece to prevent the workpiece from shifting when moving downward, so that the workpiece can pass smoothly through the induction heater 102, the spray ring 103 and the hollow chuck 4. A plurality of ball grooves are installed on the jaws of the hollow chuck 4, and balls 7 are installed in the ball grooves to facilitate the workpiece to slide down.

[0027] Reference Figure 3 The separator 301 includes an insert rod 3011 that slides through the slideway 201 , and a connecting block 3012 is installed at the end of the insert rod 3011 . The connecting block 3012 is made of iron-cobalt-nickel alloy to facilitate the adsorption and separation of the electromagnet 303 .

[0028] Reference Figure 2 The bracket 503 includes a support plate 5031 and a tapered rod 5032. The tapered rod 5032 is installed on the upper end of the support plate 5031. The axis of the tapered rod 5032 is colinear with the axis of the hollow chuck 4, which facilitates the tapered rod 5032 to receive the workpiece sliding out of the loading port.

[0029] Reference Figure 3 The lifting assembly 5 includes a driving motor 501 installed on the quenching machine body 1, a screw 502 is installed at the lower end of the driving motor 501, the lower end of the screw 502 passes through the support plate 5031 and is threadedly connected to the support plate 5031, a guide rod 504 is installed on the outer side of the screw 502 on the quenching machine body 1, the guide rod 504 slides through the support plate 5031, and the driving motor 501 drives the screw 502 to rotate, so that the detection block 6 and the tapered rod 5032 move up and down, realizing the on-off control of the workpiece receiving and the sensor, and the sensor can select a sensing element or an activation switch according to needs, such as a travel switch 8.

[0030] The implementation principle of a feeding mechanism for a quenching machine in the embodiment of the present application is:

[0031] The workpiece is placed on the slide 201, and the slide 201 guides and limits the workpiece to ensure that the workpiece can slide down along the predetermined path. When the workpiece slides to the position of the separator 301, the material dividing component 3 will act according to the signal of the travel switch 8. When the travel switch 8 does not detect the detection block 6, the electromagnet 303 is powered off, and the separator 301 is reset under the elastic force of the spring 302, releasing the workpiece. The two separators 301 approach each other to temporarily isolate the workpiece. At this time, the workpiece no longer continues to slide down and waits for the next operation. The workpiece continues to slide down under the action of gravity and falls on the tapered rod 5032 of the lifting component 5. At this time, the drive motor 501 rotates forward, driving the screw 502 to rotate, thereby driving the bracket 503 to move down along the guide rod 504. The induction heater 102 is used for heating treatment, and then the spray ring 103 is used for cooling to complete the quenching process. The quenched workpiece continues to slide down. When the conical rod 5032 moves to the appropriate position, the workpiece completely passes through the hollow chuck 4 and separates from the hollow chuck 4. The workpiece slides off the conical rod 5032, and then the drive motor 501 is controlled to reverse. The travel switch 8 detects that the detection block 6 abuts, and the electromagnet 303 is energized and absorbs the partition 301, so that the two partitions 301 are separated from each other, and the workpiece enters the loading port to complete the release of the workpiece. The conical rod 5032 moves up to the designated position to receive the next workpiece that is about to fall, and prepares for the next loading cycle, ensuring that the quenching machine body 1 can continuously and orderly quench the workpiece.
