Description

Technical Field

[0001] The utility model relates to the technical field of steel ball processing, in particular to a steel ball quenching heat treatment device. Background Art

[0002] Steel ball is a spherical iron alloy produced by forging, rolling and casting. In order to improve the wear resistance of steel balls, it is necessary to use steel ball production quenching heat treatment equipment to quench the steel balls to increase the strength of the steel ball surface and make the steel balls less prone to wear.

[0003] In the prior art, a steel ball production quenching heat treatment device disclosed in Chinese patent CN218620969U includes a supporting foot, a water tank and a quenching liquid. A water tank is fixed to the top of the supporting foot, a first solenoid valve is fixed to the bottom of the water tank, and a separation structure is provided at the bottom of the first solenoid valve. The separation structure includes a first shell, a second solenoid valve, a filter screen, a flange, a drain port and a second shell. The first shell is fixed to the bottom of the first solenoid valve, and the second solenoid valve is fixed to the bottom of the first shell. The utility model starts the motor to drive the transmission wheel to move the transmission belt, and at the same time, the salvage box drives the steel ball on the surface of the fence net to lift. When the salvage box drives the steel ball to move to the highest position, the steel ball rolls out of the inside of the salvage box and is discharged from the water tank through the discharge port, thereby realizing the easy salvage function of the device, facilitating the automatic salvage of the steel ball falling into the device, reducing the use of manpower, improving the salvage efficiency of the steel ball, and improving the convenience of the device.

[0004] However, the above-mentioned prior art solution has the following defects: in the above-mentioned technical solution, when the device is in use, each steel ball will bring out a small amount of quenching liquid during the salvage process, so that the quenching liquid is quickly reduced due to repeated operations, and the number of times the operator needs to add quenching liquid is increased, which reduces the processing efficiency and increases the cost of use. At the same time, the device cannot directly separate multiple steel balls from the quenching liquid in the water tank at the same time, resulting in different quenching times for the same batch of steel balls, thereby making the same batch of steel balls have different quenching degrees. For this reason, the utility model proposes a steel ball quenching heat treatment device for solving the above-mentioned problems. Utility Model Content

[0026] The extension and retraction of the cylinder 2 is controlled by the controller 12. When the cylinder 2 lifts the cover plate 9, the discharge box 3 sleeved in the moving frame 4 is lifted out of the quenching box 1, and the discharge box 3 is pulled out from the limit rail 13, so that the steel ball can be placed in the discharge box 3, and then the discharge box 3 is pushed into the limit rail 13, and the cylinder 2 moves in the opposite direction, so that the discharge box 3 enters the quenching box 1, which is convenient for subsequent quenching treatment.

The connecting seat 5, the connecting rod 6 and the heat dissipation hole 10 are slidably connected. The support seat 19 supports the threaded rod 7 and the motor 8, and the output end of the motor 8 is fixedly connected to the threaded rod 7, so that the threaded rod 7 is driven by the motor 8, so that the threaded rod 7 drives the threaded sleeve 18 to move, thereby facilitating the indirect control of the movement of the moving frame 4.

[0028] The material discharging box 3 is slidably pushed into the movable frame 4 and the two ends of the material discharging box 3 are flush with the ends of the limit rails 13. At this time, the upper limit block 16 sleeved on the fixed shaft 15 is rotated to rotate the limit block 16 toward the inner side of the material discharging box 3, so that the limit block 16 is inserted into the limit groove 14 provided at the bottom of the material discharging box 3, so that the limit block 16 limits the material discharging box 3, and the controller 12 drives the motor 8 to rotate.

The sleeves 18 move toward each other, and with the cooperation of the connecting rod 6, the pin shaft 17, and the connecting seat 5, the connecting seat 5 drives the moving frame 4 to move downward, thereby causing the moving frame 4 to drive the discharge box 3 to move downward until the discharge box 3 is completely immersed in the quenching liquid. When the quenching operation is completed, the motor 8 drives the threaded rod 7 to rotate in the reverse direction, thereby indirectly causing the moving frame 4 to drive the discharge box 3 to move upward until the discharge box 3 completely exits the quenching liquid and stops for a moment, so that the quenching liquid attached to the steel ball can flow back into the quenching box 1 as much as possible, thereby avoiding the quenching liquid being brought out and wasted.

Under the rotation action of the motor 8 , the motor 8 drives the threaded rod 7 to rotate in the support seat 19, so that the threaded rod 7 drives the threaded sleeve 18 to move toward each other, and under the cooperation between the connecting rod 6, the pin shaft 17, and the connecting seat 5, the connecting seat 5 drives the moving frame 4 to move downward, so that the moving frame 4 drives the discharge box 3 to move downward until the discharge box 3 is completely immersed in the quenching liquid. When the quenching operation is completed, the motor 8 drives the threaded rod 7 to rotate in the reverse direction, thereby indirectly causing the moving frame 4 to drive the discharge box 3 to move upward until the discharge box 3 completely exits the quenching liquid and stops for a while, so that the quenching liquid attached to the steel balls can flow back into the quenching box 1 as much as possible, thereby avoiding the quenching liquid being taken out and wasted, and then the same batch of steel balls can be in contact with the quenching liquid and separated from the quenching liquid at the same time, and thus the phenomenon of different quenching degrees will not occur.
