Description

Technical Field

[0001] This utility model relates to the field of quenching technology, and in particular to a fastener quenching box. Background Technology

[0002] Fasteners are a general term for mechanical parts used to fasten two or more parts or components together into a whole. Fasteners come in a wide variety of types and specifications, with different performance and applications. They are also highly standardized, serialized, and universal. Fasteners require heat treatment during processing, which includes quenching, tempering, normalizing, and annealing. Quenching is a metal heat treatment process in which a metal workpiece is heated to a certain appropriate temperature and held for a period of time, and then immersed in a quenching medium for rapid cooling. Quenching can improve the hardness and wear resistance of fasteners. The quenching process requires the use of a quenching chamber.

[0003] For example, the utility model disclosed in authorization announcement number CN221740351U discloses a fastener quenching box, which involves placing the fastener to be quenched into a heating chamber, starting a high-temperature heater to heat the fastener, controlling the baffle away from the opening of the through slot so that the heated fastener enters a collection box, and starting a spray nozzle to spray and cool the fastener, thereby obtaining the quenched fastener.

[0004] The existing technology still has the following problems when used:

[0005] After the fasteners in this device are heated, they fall down through the opening of the through groove to the bottom of the collection box. When the opening of the through groove is close to the bottom of the collection box, the collection box can collect fewer fasteners at a time, resulting in low efficiency of the device in quenching. When the opening of the through groove is far from the bottom of the collection box, the fasteners are prone to deformation when they fall down and collide with the collection box, thus reducing the processing quality of the fasteners.

[0024] Example

[0025] Please refer to Figures 1-4As shown, this utility model provides a fastener quenching box, including a quenching box body 1. The quenching box body 1 has a heating chamber and a spray chamber inside. A high-temperature heater 20 is fixedly installed on the inner wall of the heating chamber. Support legs 2 are fixedly installed at the four corners of the bottom surface of the quenching box body 1. Multiple material containers 3 are provided at the bottom of the quenching box body 1 for holding fasteners. Symmetrical mounting grooves are provided on the left and right sides of the material containers 3. Handrails 10 are fixedly installed on the inner wall of the mounting grooves. A slider 17 is fixedly installed on the bottom surface of the material containers 3. A sliding groove adapted to the slider 17 is provided on the bottom surface of the quenching box body 1. The slider 17 is slidably connected to the quenching box body 1 through the sliding groove. An inlet and an outlet adapted to the material containers 3 are respectively provided through the left and right sides of the quenching box body 1. The material containers 3 are connected to the quenching box body 1 through the inlet and outlet. The material inlet is slidably connected to the quenching box body 1. A water tank 7 and a water pump 8 are fixedly installed on the top surface of the quenching box body 1. Symmetrical water supply pipes 9 are connected to the left and right sides of the water pump 8. The water supply pipes 9 pass through the quenching box body 1 to the inside of the spray chamber and are fixedly connected to the quenching box body 1. The other end of the water supply pipe 9 is connected to a nozzle 21. The material container 3 is moved to enter the heating chamber. The high-temperature heater 20 is started to heat the fasteners inside the material container 3. After heating, the fasteners are kept warm for a period of time with the residual heat. The fasteners are prevented from being collided when they enter the spray chamber with the material container 3 in the heating chamber. The water pump 8 is started to draw water out of the water tank 7 and spray it outward along the water supply pipe 9 and the nozzle 21, thereby quickly cooling the fasteners. A drain hole connected to the outside is provided at the bottom of the material container 3.

[0026] like Figures 1-4As shown, a feeding assembly is provided below the material container 3. The feeding assembly consists of a conveyor belt 11, a mounting plate 12, a drive motor 13, a stop bar 14, a driven roller 15, and a support plate 16. The bottom surface of the slider 17 is provided with the conveyor belt 11. Symmetrical mounting plates 12 are provided on the front and rear sides of the conveyor belt 11. A support rod is fixedly provided at the bottom of the mounting plate 12. A drive motor 13 is fixedly installed on one side of the mounting plate 12. The output end of the drive motor 13 passes through the mounting plate 12 and is rotatably connected to the mounting plate 12. A drive roller and a driven roller 15 are rotatably connected between the adjacent sides of the mounting plates 12 through bearings. The conveyor belt 11 is sleeved on the outside of the drive roller and the driven roller 15. The output end of the drive motor 13 is fixedly connected to the drive roller. A support plate 16 is fixedly provided between the adjacent sides of the mounting plates 12. The top surface of the support plate 16 is flush with the conveyor belt 16. The inner side of the conveyor belt 11 is slidably connected, and multiple baffles 14 are equidistantly arranged on the outer surface of the conveyor belt 11. The conveyor belt 11 is fixedly connected to the baffles 14. The baffles 14 can position the material box 3. When the material box 3 is placed on the top surface of the conveyor belt 11 and close to another material box 3, the slider 17 on the bottom surface of the material box 3 is just close to the baffle 14. Controlling the drive motor 13 to drive the active roller to rotate can drive the conveyor belt 11 to rotate. The rotation of the conveyor belt 11 drives the driven roller 15 to rotate. The rotation of the conveyor belt 11 drives the baffles 14 to rotate. The rotation of the conveyor belt 11 drives the slider 17 and the material box 3 on the top surface of the slider 17 to move on the top surface of the conveyor belt 11, so that the fasteners enter the heating chamber and the spraying chamber in sequence for quenching. The support plate 16 can support the slider 17 and the material box 3 when the conveyor belt 11 drives the slider 17 to move.

[0027] like Figures 1-4As shown, a stirring assembly is installed above the material container 3. The stirring assembly consists of an electric telescopic rod 4, a lifting plate 5, a servo motor 6, a rotating shaft 18, and stirring rods 19. Symmetrical electric telescopic rods 4 are fixedly installed on the top surface of the quenching box 1. A lifting plate 5 is fixedly installed on the top surface of the output end of the electric telescopic rod 4. A servo motor 6 is fixedly installed on the bottom surface of the lifting plate 5. A rotating shaft 18 is fixedly installed on the bottom surface of the output end of the servo motor 6. A through hole adapted to the rotating shaft 18 is provided through the top surface of the quenching box 1. The rotating shaft 18 passes through the through hole into the heating chamber of the quenching box 1 and is slidably connected to the quenching box 1. Multiple stirring rods 19 are fixedly installed on the outside of the rotating shaft 18. A control panel is provided on the outer surface of the quenching box 1. The control panel is connected to the electric telescopic rod 4, the servo motor 6, the water pump 8, the drive motor 13, and the high-temperature heater 2. The system connects to the servo motor 6, which drives the rotating shaft 18 and stirring rod 19 to rotate. Simultaneous extension or retraction of the output end of the electric telescopic rod 4 causes the rotating shaft 18 and stirring rod 19 to move periodically up and down. When the high-temperature heater 20 is activated to heat the fasteners, the rotating shaft 18 and stirring rod 19 move downwards and extend into the material container 3 to stir the fasteners, resulting in more uniform heating. When the high-temperature heater 20 finishes heating the fasteners, the rotating shaft 18 and stirring rod 19 move upwards above the material container 3. As the material container 3 containing the heated fasteners moves to the spray chamber, another material container 3 moves directly below the stirring assembly. The periodic up and down movement of the rotating shaft 18 and stirring rod 19 during rotation allows for sequential stirring of the fasteners inside multiple material containers 3 within the heating chamber.

[0028] Specific working principle:

[0029] When using the device, the material container 3 containing the fasteners to be quenched is placed tightly against the top surface of the conveyor belt 11, with the side of the slider 17 of the material container 3 in close contact with the baffle 14. The drive motor 13 drives the active roller to rotate, which in turn drives the conveyor belt 11 to rotate. The rotation of the conveyor belt 11 drives the driven roller 15 to rotate, which in turn drives the baffle 14 to rotate. The rotation of the conveyor belt 11 causes the slider 17 and the material container 3 on the top surface of the slider 17 to move on the top surface of the conveyor belt 11. When the material container 3 enters the heating chamber inside the quenching box 1 along the feed inlet, the drive motor 13 is turned off, and the high-temperature heater 20 is started to heat the fasteners. The servo motor 6 drives the rotating shaft 18 and the stirring rod 19 to rotate, and then the output end of the electric telescopic rod 4 is simultaneously extended, causing the rotating shaft 18 and the stirring rod 19 to move downward and extend into the material container. The internal structure of container 3 can stir the fasteners, making the heating of the fasteners more uniform. When the high-temperature heater 20 finishes heating the fasteners, the rotating shaft 18 and stirring rod 19 move upward to above the container 3. After heating, the container is kept warm for a period of time with the residual heat. Then, the drive motor 13 is controlled to move the container 3 to the spray chamber. The fasteners can avoid collision when they enter the spray chamber with the container 3 in the heating chamber. When the container 3 containing the heated fasteners moves to the spray chamber, another container 3 moves directly below the stirring assembly. The rotating shaft 18 and stirring rod 19 can stir the fasteners inside the multiple containers 3 in the heating chamber in turn. The water pump 8 is started to draw water out of the water tank 7 and spray it out along the water pipe 9 and the nozzle 21, thereby quickly cooling the fasteners.
