The pushing structure can push the high-precision steel balls to move smoothly to avoid blockage of the high-precision steel balls. The discharging cylinder passes through the connecting cylinder and enters the quenching box. A discharge pipe is provided at the bottom of one end of the discharging cylinder outside the quenching box, and a closing structure is provided in the discharging pipe. During the quenching process of the high-precision steel balls, the closing structure seals the discharging cylinder in the quenching box to avoid the high-precision steel balls rolling out of the discharge pipe during the quenching process. After the quenching of the high-precision steel balls is completed, the closing structure is started to open the discharge pipe to facilitate the quenched high-precision steel balls to flow into the discharge pipe and be discharged from the discharge pipe on the discharge pipe, thereby completing the discharging of the high-precision steel balls after quenching, and can improve the discharging rate of the high-precision steel balls after quenching.

[0007] Preferably, the driving structure includes a driving motor and a driving gear. The driving motor is arranged on a vertical plate, and a transmission shaft is arranged on the driving motor. The driving gear is arranged on the transmission shaft. Driven gears are arranged on the connecting cylinders at both ends of the quenching box, and the driven gears are meshed and connected with the driving gears, so that the driven gears drive the connecting cylinder to rotate around the feed cylinder and the discharge cylinder. The driving motor drives the transmission shaft and the driving gear on the transmission shaft to rotate, and the driving gear drives the driven gear to rotate. The driven gear drives the connecting cylinder to rotate around the feed cylinder and the discharge cylinder to rotate the quenching box. The high-precision steel balls in the quenching box rotate with the quenching box, and the partition prevents the high-precision steel balls from rolling. When the high-precision steel balls move to the upper side with the quenching box, gravity causes the high-precision steel balls to roll off the surface of the partition, and eventually fall to the bottom of the quenching box and rise with the rotating quenching box, repeating the rising, falling, and rising actions. The heat in the quenching box quenches the high-precision steel balls during the rising and falling processes, and the high-precision steel balls are fully quenched to enhance the quenching quality of the high-precision steel balls.

[0008] Preferably, the pushing structure includes a transmission motor and an auger. A feed bin is provided on the top of the feed barrel outside the quenching box. The transmission motor is provided on the outer wall of the feed barrel outside the quenching box. The auger is provided in the feed barrel, and one end of the auger is connected to the transmission motor. High-precision steel balls that need heat treatment and quenching are poured into the feed bin, and the high-precision steel balls in the feed bin fall into the feed barrel. The transmission motor is started, and the transmission motor drives the auger to rotate. The auger pushes the high-precision steel balls forward in the feed barrel and falls into the quenching box through the drop pipe.

[0009] Preferably, a spring rod is provided on one end of the feed barrel in the quenching box, and the spring rod is movably connected to the closed structure. The high-precision steel balls that fall into the quenching box rotate with the quenching box, and the partition prevents the high-precision steel balls from rolling. When the high-precision steel balls move upward with the quenching box, gravity causes the high-precision steel balls to roll from the surface of the partition, and the fallen high-precision steel balls fall on the spring rod and are bounced up, eventually falling to the bottom of the quenching box and rising with the rotating quenching box, repeating the actions of rising, falling, and rising to fully quench the high-precision steel balls.

The hydraulic cylinder is arranged on one end of the discharge barrel outside the quenching box, and a piston rod is arranged on the hydraulic cylinder, which extends the piston rod into the discharge barrel. The baffle is arranged in the quenching box, and the baffle is connected to the piston rod. An inner groove for the spring rod to penetrate is arranged on the piston rod, and the inner groove passes through the baffle. The hydraulic cylinder is started, and the hydraulic cylinder pulls the baffle through the piston rod. The baffle approaches the discharge barrel to seal the discharge barrel in the quenching box to prevent high-precision steel balls from rolling out of the discharge barrel during the quenching process. After the quenching of the high-precision steel balls is completed, the closed structure is started to open the discharge pipe to facilitate the quenched high-precision steel balls to flow into the discharge pipe and be discharged from the discharge pipe on the discharge pipe, thereby completing the unloading of the high-precision steel balls after quenching, and can improve the unloading rate of the high-precision steel balls after quenching.

[0011] Preferably, a guide plate is provided at the bottom of the baffle, and the guide plate is arranged as an arc-shaped structure with an opening upward.

[0012] Preferably, a partition is provided on the inner wall of the quenching box, and the partition is arranged as an inclined structure on the inner wall of the quenching box. The high-precision steel ball falling into the quenching box rotates with the quenching box, and the partition prevents the high-precision steel ball from rolling. When the high-precision steel ball moves upward with the quenching box, gravity causes the high-precision steel ball to roll off the surface of the partition, and the fallen high-precision steel ball falls on the spring rod and is bounced up, and finally falls to the bottom of the quenching box and rises with the rotating quenching box, repeating the actions of rising, falling, and rising. The heat in the quenching box quenches the high-precision steel balls in the rising and falling process. The high-precision steel balls rise and fall multiple times in the quenching box, and the high-precision steel balls are fully quenched to enhance the quenching quality of the high-precision steel balls.

[0013] Preferably, the quenching box is provided with a heat conducting plate, and the two sides of the heat conducting plate are respectively extended into the quenching box and the heating chamber, and the electric heating block is started to make the heating wire between the electric heating blocks work to generate heat.

[0017] 3. Pour the high-precision steel balls that need heat treatment and quenching into the feed bin. The high-precision steel balls in the feed bin fall into the feed barrel. Start the transmission motor, which drives the auger to rotate. The auger pushes the high-precision steel balls forward in the feed barrel and falls into the quenching box through the drop pipe.

[0018] Fourth, the high-precision steel ball that falls into the quenching box rotates with the quenching box, and the partition prevents the high-precision steel ball from rolling. When the high-precision steel ball moves to the upper side with the quenching box, gravity causes the high-precision steel ball to roll down from the surface of the partition, and the fallen high-precision steel ball falls on the spring rod and is bounced up, and finally falls to the bottom of the quenching box, and rises with the rotating quenching box, repeating the action of rising, falling, and rising.

After the high-precision steel ball quenching treatment is completed, turn off the transmission motor, stop inputting high-precision steel balls into the quenching box, turn off the electric heating block, stop transmitting heat into the quenching box, start the hydraulic cylinder, and the hydraulic cylinder pushes the baffle to move through the piston rod, so that the spring rod is inserted into the inner groove on the piston rod, and the guide plate on the baffle is pulled out from the drop tube. The high-precision steel balls that rise with the rotating quenching box fall down and fall into the guide plate, roll along the guide plate into the discharge barrel, and are finally discharged from the discharge pipe;

[0020] 6. After the high-precision steel balls are completely discharged, turn off the drive motor, stop the rotation of the quenching box, clean the impurities generated by the high-precision steel balls during the quenching process, and cut off the power supply.

The driving motor drives the transmission shaft and the driving gear on the transmission shaft to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the connecting cylinder to rotate around the feed cylinder and the discharge cylinder, so that the quenching box rotates, and the high-precision steel balls in the quenching box rotate with the quenching box. The partition prevents the high-precision steel balls from rolling. When the high-precision steel balls move to the upper side with the quenching box, the gravity causes the high-precision steel balls to roll down from the surface of the partition, and eventually fall to the bottom of the quenching box and rise with the rotating quenching box, repeating the rising, falling, and rising actions. The heat in the quenching box quenches the high-precision steel balls in the rising and falling process, and fully quenches the high-precision steel balls to enhance the quenching quality of the high-precision steel balls;

[0023] 2. The hydraulic cylinder pulls the baffle through the piston rod, and the baffle is close to the discharge barrel to seal the discharge barrel in the quenching box to prevent the high-precision steel balls from rolling out of the discharge barrel during the quenching process. After the quenching of the high-precision steel balls is completed, the discharge pipe is opened, and the high-precision steel balls that rise with the rotating quenching box fall down and fall into the guide plate, roll along the guide plate into the discharge barrel, and are finally discharged from the discharge pipe, completing the discharge of the high-precision steel balls after quenching, which can improve the discharge rate of the high-precision steel balls after quenching;

The heat treatment and quenching device for high-precision steel ball processing according to claim 1 or 7, characterized in that: The quenching box is provided with a heat conducting plate, and two sides of the heat conducting plate are respectively extended into the quenching box and the heating cavity.

9. An operating method applicable to the heat treatment and quenching device for high-precision steel ball processing as claimed in claim 1, characterized in that: The operation method comprises the following steps:

1. Check whether the circuit of the heat treatment quenching device for high-precision steel ball processing is intact, and check whether the drive motor, transmission motor, hydraulic cylinder, and electric heating block are working properly; Second, start the electric heating block to make the electric heating wire between the electric heating blocks work to generate heat, start the hydraulic cylinder, the hydraulic cylinder pulls the baffle through the piston rod, the baffle is close to the discharge barrel, and the discharge barrel in the quenching box is sealed, start the drive motor, the drive motor drives the transmission shaft and the drive gear on the transmission shaft to rotate, the drive gear drives the driven gear to rotate, and the driven gear drives the connecting barrel to rotate around the feed barrel and the discharge barrel to rotate the quenching box; 3. Pour the high-precision steel balls that need heat treatment and quenching into the feed bin. The high-precision steel balls in the feed bin fall into the feed barrel. Start the transmission motor, which drives the auger to rotate. The auger pushes the high-precision steel balls forward in the feed barrel and falls into the quenching box through the drop pipe. Fourth, the high-precision steel ball that falls into the quenching box rotates with the quenching box, and the partition prevents the high-precision steel ball from rolling. When the high-precision steel ball moves to the upper side with the quenching box, gravity causes the high-precision steel ball to roll down from the surface of the partition, and the fallen high-precision steel ball falls on the spring rod and is bounced up, and finally falls to the bottom of the quenching box, and rises with the rotating quenching box, repeating the action of rising, falling, and rising. The heat in the quenching box quenches the high-precision steel ball in the process of rising and falling; 5. After the high-precision steel ball quenching treatment is completed, turn off the transmission motor, stop inputting high-precision steel balls into the quenching box, turn off the electric heating block, stop transmitting heat into the quenching box, start the hydraulic cylinder, and the hydraulic cylinder pushes the baffle to move through the piston rod, so that the spring rod is inserted into the inner groove on the piston rod, and the guide plate on the baffle is pulled out from the drop tube. The high-precision steel balls that rise with the rotating quenching box fall down and fall into the guide plate, roll along the guide plate into the discharge barrel, and are finally discharged from the discharge pipe; 6. After the high-precision steel balls are completely discharged, turn off the drive motor, stop the rotation of the quenching box, clean up the impurities generated during the quenching process of the high-precision steel balls, and cut off the power supply.
