Description

Technical Field

[0001] This utility model relates to the field of wear-resistant steel ball production technology, specifically a quenched spiral propeller device. Background Technology

[0002] Currently, in the production lines of wear-resistant steel balls or segments, the steel balls or segments require heat treatment after forming, which includes quenching. To ensure the stability of the quality of the steel balls or segments, there are high requirements for factors such as the uniformity of the quenching temperature and the quenching time.

[0003] In mass production, the production line requires equipment that can both uniformly quench steel balls or steel segments and ensure sufficient quenching time. Currently, a spiral blade propeller is used, with a thick-walled tube as the central rotating shaft and the spiral made of steel plate that has been cut, bent, and welded to the central rotating shaft.

[0004] However, the currently used spiral blade propellers still have some shortcomings in operation. Firstly, the spiral blades are made of solid steel plates welded together, resulting in relatively independent spaces between the two blades. This causes the temperature near the initial steel ball or segment during quenching to be higher, while the temperature in subsequent areas is lower, making it impossible to guarantee the uniformity of the quenching fluid temperature in the tank. This uneven temperature directly leads to inconsistent quenching results for the steel balls or segments, making it difficult to meet the production requirements for high-quality steel balls or segments. Secondly, there is a lack of effective automatic lubrication mechanisms for the bearings, usually requiring manual periodic oiling, which is time-consuming and labor-intensive. Furthermore, when the spiral central shaft malfunctions and needs replacement or repair, the traditional equipment's structural design makes the disassembly process complex and cumbersome. It often requires the use of various specialized tools, consuming significant manpower and time, further extending equipment downtime and reducing production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a quenching spiral propeller device. Firstly, the spiral blades are made of solid steel plates welded together, resulting in relatively independent spaces between the two blades. This leads to a higher temperature near the initial steel ball during quenching, while subsequent areas experience lower temperatures, making it impossible to guarantee the uniformity of the quenching liquid temperature in the tank. This uneven temperature directly results in inconsistent quenching effects for the steel balls, failing to meet the production requirements for high-quality steel balls. Secondly, the lack of an effective automatic lubrication mechanism for the bearings necessitates periodic manual oiling, which is time-consuming and labor-intensive. Furthermore, when the spiral central shaft malfunctions and needs replacement or repair, the traditional device's structural design makes disassembly complex and cumbersome. It often requires various specialized tools, consuming significant manpower and time, further extending equipment downtime and reducing production efficiency.

[0006] This utility model provides the following technical solution: a quenching spiral propeller device, including a water tank and a spiral central shaft. Spiral blades are fixedly sleeved on the outer surface of the spiral central shaft. Support seats are fixedly connected to both ends of the water tank. Bearing seats are fixedly connected to the upper surfaces of the two support seats. Shafts are installed on the two bearing seats. Connecting rods are fixedly connected to one end of the two shafts. The spiral central shaft is installed between the two connecting rods. Oil injection holes are opened on the upper surfaces of the two bearing seats. Multiple through holes are opened on the surface of the spiral blades.

[0007] Two support plates are fixedly connected between the two inner side walls of the water tank, and each of the two support plates is equipped with a refueling component.

[0008] Preferred technical solution 1: The refueling assembly includes an oil storage tank fixedly installed on the support plate. The oil storage tank stores lubricating oil inside. An oil pump is fixedly installed on the upper surface of the support plate. The oil pump has an oil inlet pipe connected to its oil inlet end and an oil outlet pipe connected to its oil outlet end. One end of the oil inlet pipe is connected to the oil storage tank, and one end of the oil outlet pipe extends to the bottom of the support plate and is connected to the oil filling hole of the bearing seat.

[0009] Preferred technical solution 2: The oil pump is a plunger pump and is driven by a motor, and both the oil inlet pipe and the oil outlet pipe are made of oil-resistant and pressure-resistant rubber hoses.

[0010] Preferred technical solution 3: The surfaces of both oil storage tanks are provided with transparent observation windows, and the tops of both oil storage tanks are provided with filling ports, with sealing plugs inserted into the filling ports.

[0011] Preferred technical solution four: Both ends of the spiral central shaft are fixedly connected with locking blocks, the surfaces of the two connecting rods are provided with locking grooves that match the locking blocks, the surfaces of the two locking blocks are provided with a set of threaded holes, the surfaces of the two connecting rods are provided with a set of threaded grooves, the two sets of threaded holes are matched with the two sets of threaded grooves, and bolts are threaded between the corresponding threaded grooves and the corresponding threaded holes. The bolts are internal hex bolts.

[0012] Preferred technical solution five: One side of the water tank is connected to an inlet pipe, and the other side of the water tank is connected to an outlet pipe. Both the inlet pipe and the outlet pipe are connected to an external pipe.

[0013] Compared with the prior art, this utility model provides a quenching spiral propeller device with the following advantages: the external motor drives the shaft and the spiral central shaft to rotate, thereby pushing the steel balls to be quenched to move inside the water tank through the spiral blades. Multiple steel balls can be quenched sequentially. At the same time, the through holes allow the quenching liquid inside the water tank to circulate, making the temperature of the quenching liquid inside the water tank uniform. This prevents the temperature from being high at the ball and low at the far end, thus keeping the water temperature in the quenching water tank constant and meeting the requirements for stable process water temperature.

[0014] Meanwhile, during use, the lubricating oil inside the oil storage tank can be drawn out by the oil pump and delivered to the bearing housing through the oil outlet pipe for automatic oil lubrication, thus extending the service life of the bearing.

[0015] When the spiral center shaft needs to be disassembled for replacement or repair, the bolts can be removed using a hex wrench, and the spiral center shaft can be taken off the connecting rod for replacement or repair, which is convenient and quick. Attached Figure Description

[0021] Please see Figure 1-4 ,

[0022] Example 1: A quenching spiral propeller device includes a water tank 1 and a spiral central shaft 2. Spiral blades 3 are fixedly sleeved on the outer surface of the spiral central shaft 2. Support seats 4 are fixedly connected to both ends of the water tank 1. Bearing seats 5 are fixedly connected to the upper surface of the two support seats 4. Shaft rods 6 are installed on the two bearing seats 5. Connecting rods 7 are fixedly connected to one end of the two shaft rods 6. The spiral central shaft 2 is installed between the two connecting rods 7. Oil injection holes are opened on the upper surface of the two bearing seats 5. Multiple through holes 19 are opened on the surface of the spiral blades 3.

[0023] Two support plates 8 are fixedly connected between the two inner side walls of the water tank 1, and each support plate 8 is equipped with a refueling component 9.

[0024] Example 2: The difference between this example and Example 1 is that the refueling component 9 includes an oil storage tank 10 fixedly installed on the support plate 8. The oil storage tank 10 stores lubricating oil. An oil pump 11 is fixedly installed on the upper surface of the support plate 8. The oil inlet end of the oil pump 11 is connected to an oil inlet pipe 12, and the oil outlet end of the oil pump 11 is connected to an oil outlet pipe 13. One end of the oil inlet pipe 12 is connected to the oil storage tank 10, and one end of the oil outlet pipe 13 extends to the bottom of the support plate 8 and is connected to the oil filling hole of the bearing seat 5, which facilitates the lubrication of the interior of the bearing seat 5 and extends its service life.

[0025] Example 3: The difference between this example and Example 1 is that the oil pump 11 is a plunger pump and is driven by a motor. The oil inlet pipe 12 and the oil outlet pipe 13 are both made of oil-resistant and pressure-resistant rubber pipes, which facilitates lubrication operations.

[0026] Example 4: The difference between this example and Example 1 is that both oil storage tanks 10 have transparent observation windows 14 on their surfaces, and both oil storage tanks 10 have oil filling ports on their tops. Sealing plugs are inserted into the oil filling ports to facilitate observation of the internal condition of the oil storage tanks 10 and to facilitate the addition of lubricating oil.

[0027] Example 5: The difference between this example and Example 1 is that both ends of the spiral central shaft 2 are fixedly connected with locking blocks 15, the surfaces of the two connecting rods 7 are provided with locking grooves 16 that match the locking blocks 15, the surfaces of the two locking blocks 15 are provided with a set of threaded holes 17, the surfaces of the two connecting rods 7 are provided with a set of threaded grooves 18, the two sets of threaded holes 17 are matched with the two sets of threaded grooves 18, and bolts 20 are threaded between the corresponding threaded grooves 18 and the corresponding threaded holes 17. The bolts 20 are internal hex bolts, which facilitates the installation and disassembly of the spiral central shaft 2 and makes it easy to replace and repair it.

[0028] Example 6: The difference between this example and Example 1 is that one side of the water tank 1 is connected to an inlet pipe, and the other side of the water tank 1 is connected to an outlet pipe. Both the inlet and outlet pipes are connected to external pipes to facilitate the circulation of the quenching liquid in the water tank 1, ensuring the quenching effect.

[0029] In summary, this quenching spiral propeller device uses an external motor to drive the shaft 6 and the spiral central shaft 2 to rotate, thereby pushing the steel balls to be quenched to move inside the water tank through the spiral blades 3. Multiple steel balls can be quenched sequentially. At the same time, the through hole 19 allows the quenching liquid inside the water tank 1 to circulate, ensuring that the temperature of the quenching liquid inside the water tank 1 is uniform and that the temperature is not high at the ball and low further away from the ball, thus keeping the water temperature inside the quenching water tank 1 constant and meeting the requirements for stable process water temperature.

[0030] Meanwhile, during use, the lubricating oil inside the oil storage tank 10 can be drawn out by the oil pump 11 and delivered to the bearing housing 5 through the oil outlet pipe 13 for automatic oil injection and lubrication, thereby extending the service life of the bearing.

[0031] When the spiral center shaft 2 needs to be disassembled for replacement or repair, the bolt 20 can be removed with a hex wrench, and the spiral center shaft 2 can be removed from the connecting rod 7 for replacement or repair, which is convenient and quick.
