Description

Technical Field

[0001] This utility model belongs to the field of steel ball manufacturing technology, and in particular relates to a quenching device for heat treatment of steel balls. Background Technology

[0002] The production of steel balls requires multiple processes, among which quenching is a crucial heat treatment process. Its main purpose is to improve the hardness, wear resistance, and fatigue strength of the steel balls. Publication number CN218755893U discloses a quenching and cooling device for steel ball heat treatment. This utility model relates to the field of steel ball processing technology. This quenching and cooling device for steel ball heat treatment includes a shell. A lifting device is installed on the inner wall of the shell. The lifting device includes a fixed rod. A large gear is rotatably connected to the end of the fixed rod away from the inner wall of the shell. A driving gear meshes with the outer surface of the large gear. A motor is rotatably connected to the end of the driving gear away from the large gear. One end of the driving gear is connected to the output end of the motor. A driven gear meshes with the outer surface of the large gear. A bolt is fixedly connected to the end of the driven gear away from the outer surface of the large gear. A nut is fitted onto the outer surface of the bolt. A storage frame is fixedly connected to the side of the nut away from the inner wall of the shell. A partition is fixedly connected to the bottom surface of the inner cavity of the storage frame, achieving the effect of facilitating the retrieval of the steel balls after quenching and cooling.

[0003] However, existing technologies have some problems: existing quenching devices for heat treatment of steel balls typically place the steel balls to be quenched in a container and then immerse the container in a quenching tank for quenching. However, placing a bunch of steel balls in a container for quenching causes the quenching medium in the quenching tank to absorb a large amount of heat instantly, resulting in excessively high temperatures and affecting the quenching effect of the steel balls. In addition, this method requires removing the steel balls after quenching and then adding new steel balls for quenching, which is cumbersome, cannot be automated, and has low production efficiency. Therefore, we propose a quenching device for heat treatment of steel balls. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a quenching device for heat treatment of steel balls, which controls the quenching time and temperature of steel balls through a cylinder and turntable circulation assembly, thereby improving the quenching quality of steel balls.

[0005] This utility model is implemented as follows: a quenching device for heat treatment of steel balls includes a support, a cylinder fixedly connected to the support, a turntable rotatably connected inside the cylinder, a driving component inside the support for driving the turntable to rotate, a conveying component fixedly connected to one side of the cylinder, a ball outlet on the other side of the cylinder, a collecting component at the ball outlet, a quenching tank fixedly connected to one side of the support, and a circulation component on the quenching tank.

[0006] Optionally, the turntable includes a conical disc, on which multiple sets of conical baffles are fixedly connected. The multiple sets of conical baffles are evenly distributed circumferentially on the outer wall of the conical disc, and drainage holes are provided on the conical baffles.

[0007] Optionally, the drive assembly includes a motor, which is fixedly connected to the bracket, and the output end of the motor is fixedly connected to a main gear.

[0008] Optionally, the drive assembly further includes a shaft and a chain, one end of the shaft being fixedly connected to a conical disc, the other end of the shaft being fixedly connected to a driven gear, and the chain being sleeved on the master gear and the driven gear.

[0009] Optionally, the conveying assembly includes a conveying platform, a ball inlet is provided on one side of the cylinder, the conveying platform is fixedly connected to the ball inlet of the cylinder, a conveyor belt is rotatably connected to the conveying platform, and several partitions are fixedly connected to the conveyor belt.

[0010] Optionally, the collecting assembly includes a ball outlet, one end of which is fixedly connected to the ball outlet of the cylinder, and the other end of which is fixedly connected to a collecting box.

[0011] Optionally, the quenching tank is provided with a quenching medium, and a water inlet is provided at the lower end of the cylinder, wherein the quenching medium is submerged in the water inlet.

[0012] Optionally, the circulation component includes a water outlet pipe, which is fixedly connected to the lower end of the quenching tank. A water pump is connected to the water outlet pipe, and a cooler is connected to the water pump. The cooler is connected to a water inlet pipe, which is fixedly connected to the upper end of the quenching tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a drive component, which can drive the main gear to rotate through a motor, and the main gear then drives the driven gear to rotate through a chain, thereby causing the turntable to rotate, and in turn causing the steel ball inside the cylinder to rotate. By controlling the speed of the motor, the speed of the turntable can be controlled, which in turn controls the moving speed of the steel ball. Thus, this device can control the quenching time of the steel ball according to the material and size of the steel ball, thereby improving the quenching quality of the steel ball.

[0015] 2. The turntable of this utility model is composed of a conical disc and multiple sets of conical baffles. A cavity is formed between the conical disc and the cylinder. The multiple sets of conical baffles further divide the cavity into independent ball storage chambers. The ball outlet is at the cone head of the conical disc, and the ball inlet is at the cone tail. This allows the steel balls to be quenched to easily enter from the ball inlet and easily exit from the ball outlet, avoiding the accumulation or blockage of steel balls. The automatic quenching of steel balls is completed by the conveying and collecting components, which accelerates the quenching efficiency of steel balls.

[0016] 3. This utility model is equipped with a circulation component. The water pump delivers the quenching medium from the quenching tank to the cooler through the outlet pipe for cooling. After cooling, the quenching medium is then added back to the quenching tank through the inlet pipe to quench the steel balls. This ensures that the temperature of the quenching medium in the quenching tank is always maintained within a certain range, guaranteeing the quenching quality of the steel balls. In addition, when dealing with steel balls of different materials, the temperature of the quenching medium can be changed by altering the cooling effect of the cooler, allowing this device to quench steel balls of different materials.

[0024] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown in the figure, the present invention provides a quenching device for heat treatment of steel balls, including a bracket 1, which is made of stainless steel. The main function of the bracket 1 is to support the entire device.

[0026] Furthermore, a cylinder 2 is fixedly connected to the support 1, and a turntable 3 is rotatably connected inside the cylinder 2. The turntable 3 includes a conical disk 301, and multiple sets of conical baffles 302 are fixedly connected to the conical disk 301. The multiple sets of conical baffles 302 are evenly distributed on the outer wall of the conical disk 301 in a circular pattern. Drainage holes are provided on the conical baffles 302. The function of the drainage holes is to prevent the conical baffles 302 from carrying away the quenching medium when rotating.

[0027] Specifically, a cavity is formed between the conical disk 301 and the cylinder 2, and multiple sets of conical baffles 302 further divide the cavity into independent ball storage chambers. The ball outlet is at the cone head of the conical disk 301, and the ball inlet is at the cone tail. This allows the steel balls to be quenched to easily enter through the ball inlet and exit through the ball outlet via the conveying assembly 5, preventing the steel balls from clogging the inlet and outlet during operation.

[0028] Furthermore, a drive assembly 4 is provided inside the bracket 1. The drive assembly 4 is used to drive the turntable 3 to rotate. The drive assembly 4 includes a motor 401, which is fixedly connected to the bracket 1. The output end of the motor 401 is fixedly connected to a main gear 402.

[0029] Furthermore, the drive assembly 4 also includes a shaft 403 and a chain 405. One end of the shaft 403 is fixedly connected to the conical disk 301, and the other end of the shaft 403 is fixedly connected to a driven gear 404. The chain 405 is sleeved on the master gear 402 and the driven gear 404.

[0030] Specifically, the motor 401 starts and drives the main gear 402 to rotate. The main gear 402 then drives the driven gear 404 to rotate via the chain 405. After the driven gear 404 rotates, it drives the rotating shaft 403 to rotate. The rotating shaft 403 drives the conical disk 301 and the conical baffle 302 to rotate, thereby causing the steel balls that have entered the ball storage chamber separated by the conical baffle 302 to rotate, and then causing the steel balls to rotate into the quenching pool 7 for quenching.

[0031] Furthermore, this device can control the rotation speed of the turntable 3 by controlling the rotation speed of the motor 401, thereby changing the time the steel ball stays in the quenching tank 7. This allows the device to adjust the rotation speed of the motor 401 according to the size of the steel ball, so that the time the steel ball stays in the quenching tank 7 can be determined according to its size. This ensures that the steel ball can fully contact the quenching medium during quenching, thus improving the quenching quality of the steel ball.

[0032] Furthermore, a conveying assembly 5 is fixedly connected to one side of the cylinder 2. The conveying assembly 5 includes a conveying platform 501. A ball inlet is opened on one side of the cylinder 2. The conveying platform 501 is fixedly connected to the ball inlet of the cylinder 2. A conveyor belt 502 is rotatably connected to the conveying platform 501. Several partitions 503 are fixedly connected to the conveyor belt 502.

[0033] Specifically, a driving component is provided on the conveyor table 501 to drive the conveyor belt 502 to rotate. The conveyor belt 502 is used to transport the steel balls into the cylinder 2. The partition 503 on the conveyor belt 502 is used to divide and block the conveyor belt 502 so that the steel balls will not fall off the conveyor belt 502 during transportation, and at the same time, it avoids a large number of steel balls being transported to the ball inlet at the same time, which would cause the steel balls to accumulate or block.

[0034] Furthermore, a ball outlet is provided on the other side of the cylinder 2, and a collection component 6 is provided at the ball outlet of the cylinder 2. The collection component 6 includes a ball outlet platform 601, which is tilted at a certain angle to facilitate the rolling of the steel ball. One end of the ball outlet platform 601 is fixedly connected to the ball outlet of the cylinder 2, and the other end of the ball outlet platform 601 is fixedly connected to a collection box 602.

[0035] Specifically, the quenched steel balls are transported to the ball outlet via turntable 3, and then transported to the collection box 602 via ball outlet platform 601 for collection.

[0036] A quenching pool 7 is fixedly connected to one side of the bracket 1. The quenching pool 7 contains a quenching medium for quenching the steel ball. A water inlet is provided at the lower end of the cylinder 2. The quenching medium is submerged in the water inlet, so that the quenching medium can enter the cylinder 2 and contact the steel ball inside, thereby quenching it.

[0037] Furthermore, a circulation component 8 is provided on the quenching pool 7. The circulation component 8 includes a water outlet pipe 801, which is fixedly connected to the lower end of the quenching pool 7. A water pump 802 is connected to the water outlet pipe 801, and a cooler 803 is connected to the water pump 802. The cooler 803 is connected to a water inlet pipe 804, which is fixedly connected to the upper end of the quenching pool 7.

[0038] Specifically, the water pump 802 extracts the quenching medium from the quenching pool 7 through the water outlet pipe 801, and then enters the cooler 803 for cooling. After cooling, the medium is added back into the quenching pool 7 through the water inlet pipe 804, thereby keeping the temperature of the quenching medium in the quenching pool 7 within a certain range and ensuring the quality of the steel ball quenching.

[0039] The working principle of this utility model is as follows:

[0040] This utility model is equipped with a drive component 4, which can drive the main gear 402 to rotate via a motor 401. The main gear 402 then drives the driven gear 404 to rotate via a chain 405, thereby causing the turntable 3 to rotate, which in turn causes the steel ball inside the cylinder 2 to rotate. By controlling the rotation speed of the motor 401, the rotation speed of the turntable 3 can be controlled, which in turn controls the moving speed of the steel ball. This allows the device to control the quenching time of the steel ball according to its material and size, thereby improving the quenching quality of the steel ball.

[0041] The turntable 3 of this utility model consists of a conical disc 301 and multiple sets of conical baffles 302. A cavity is formed between the conical disc 301 and the cylinder 2. The multiple sets of conical baffles 302 further divide the cavity into independent ball storage chambers. The ball outlet is at the cone head of the conical disc 301, and the ball inlet is at the cone tail. This allows the steel balls to be quenched to easily enter from the ball inlet and easily exit from the ball outlet, avoiding the accumulation or blockage of steel balls. The automatic quenching of the steel balls is completed by the conveying component 5 and the collecting component 6, which accelerates the quenching efficiency of the steel balls.

[0042] This utility model is equipped with a circulation component 8. The water pump 802 transports the quenching medium from the quenching tank 7 to the cooler 803 for cooling through the water outlet pipe 801. After cooling, the quenching medium is then added back to the quenching tank 7 through the water inlet pipe 804 to quench the steel balls. This ensures that the temperature of the quenching medium in the quenching tank 7 is always maintained within a certain range, guaranteeing the quenching quality of the steel balls. At the same time, when dealing with steel balls of different materials, the temperature of the quenching medium can be changed by altering the cooling effect of the cooler 803, allowing this device to quench steel balls of different materials.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
