Description

Technical Field

[0001] This utility model relates to a tempering device, specifically a high-efficiency tempering device for wear-resistant steel balls, belonging to the field of tempering technology for wear-resistant steel balls. Background Technology

[0002] To improve the overall strength and quality of wear-resistant steel balls after production, they are tempered after quenching. Tempering has a significant impact on the performance of wear-resistant steel balls, so the tempering device needs to have precise temperature and time control functions.

[0003] A high-efficiency tempering device for wear-resistant steel balls disclosed in Chinese Patent Application Publication CN221117542U includes a base, a heating cylinder fixedly connected to the top right side of the base, a power frame fixedly connected to the top of the heating cylinder, and a second bevel gear rotatably connected to the right side of the inner wall of the power frame. Using this technical solution, a first electric motor drives a vertical stirring rod and a horizontal stirring rod to move the steel balls, ensuring uniform heating and accelerating the heating efficiency. A second electric motor rotates in the opposite direction, moving the heated steel balls to the left until they fall into a water storage tank through the discharge port. The cooling process is carried out to prevent workers from coming into contact with the heated steel balls through the spiral rod, thus avoiding skin contact and burns. However, the above technical solution only uses the rotating spiral rod to transport the steel balls to the bottom of the heating cylinder for stirring and heating. Since the channel for transporting the steel balls in the heating cylinder is connected to the outside, the temperature at the bottom of the heating cylinder is lower than that at the top. The steel balls are only heated by horizontal stirring with the stirring rod, which cannot lift the steel balls to the top of the heating cylinder and move them for uniform heating. This reduces the heating efficiency of the tempering device and consequently reduces the tempering efficiency of the wear-resistant steel balls.

[0004] Therefore, a high-efficiency tempering device for wear-resistant steel balls is proposed here. Utility Model Content

[0005] This invention proposes a high-efficiency tempering device for wear-resistant steel balls to solve the problem in the prior art that the steel balls cannot be lifted to the upper part of the heating cylinder and moved for uniform heating.

[0006] This utility model is achieved through the following technical solution: a high-efficiency tempering device for wear-resistant steel balls, including a heating cylinder, wherein a connecting lifting mechanism is provided on the outside and inside of the heating cylinder;

[0007] The connecting lifting mechanism includes a conveying pipe, the right side of which is fixedly connected to the outer surface of the heating cylinder, a feeding hopper fixedly connected to the outer surface of the conveying pipe, a heating sleeve fixedly connected to the outer surface of the heating cylinder, and support legs arranged in an equidistant circle fixedly connected to the upper surface of the heating cylinder. A mounting frame is fixedly connected to the outer surfaces of several support legs. A hydraulic telescopic rod is provided above the mounting frame, the telescopic end of which is slidably connected to the inside of the mounting frame. A lifting ventilation plate is fixedly connected to the telescopic end of the hydraulic telescopic rod, and the lifting ventilation plate is slidably connected to the inside of the heating cylinder. The bottom surface of the lifting ventilation plate is in contact with the inner bottom wall of the heating cylinder.

[0008] A rotating component is provided above the connecting lifting mechanism, and a cooling component is provided below the connecting lifting mechanism.

[0009] The rotating assembly includes an upper top frame, the top of each of the supporting legs is fixedly connected to the bottom surface of the upper top frame, a rotating motor is fixedly connected to the inner wall of the upper top frame, the output end of the rotating motor is fixedly connected to the upper surface of the hydraulic telescopic rod, the telescopic end of the hydraulic telescopic rod is rotatably connected to the inside of the mounting frame, and the lifting ventilation plate is rotatably connected to the inside of the heating cylinder.

[0010] The cooling assembly includes a support platform, the upper surface of which is fixedly connected to the bottom surface of the heating cylinder, and a lower base plate is fixedly connected to the bottom surface of the support platform.

[0011] A water storage and cooling tank is fixedly connected to the upper surface of the lower base plate, and the upper surface of the water storage and cooling tank is fixedly connected to the outer surface of the conveying pipeline.

[0012] A switch valve is fixedly connected to the outer surface of the water storage cooling tank, and a drain pipe is fixedly connected to the output end of the switch valve.

[0013] A conveying motor is fixedly connected to the left side of the conveying pipe. A rotating rod is fixedly connected to the output end of the conveying motor.

[0014] This utility model provides a high-efficiency tempering device for wear-resistant steel balls, which has the following beneficial effects:

[0015] 1. This high-efficiency tempering device for wear-resistant steel balls, because the heating cylinder is connected to the conveying pipe and the feeding hopper, causes the hot air below the heating cylinder to be lost, resulting in a lower temperature at the bottom of the heating cylinder. By controlling the power supply of the hydraulic telescopic rod, the lifting ventilation plate carries the steel ball to be heated to the upper position of the heating cylinder, thereby improving the heating efficiency of the tempering device and thus improving the tempering processing efficiency of the wear-resistant steel ball.

[0016] 2. This high-efficiency tempering device for wear-resistant steel balls utilizes the upper frame of the rotating component to mount and fix the rotating motor above the hydraulic telescopic rod. The rotating motor drives the hydraulic telescopic rod to rotate, causing the lifting ventilation plate to rotate inside the heating cylinder. This facilitates the movement of multiple steel balls requiring heating on the lifting ventilation plate, ensuring uniform heating of the steel balls and further improving the heating efficiency of the tempering device, thereby further enhancing the tempering processing efficiency of the wear-resistant steel balls.

The telescopic end of the hydraulic telescopic rod 205 is rotatably connected to the inside of the mounting frame 204.

Using the rotating motor 302 fixed to the upper top frame 301, the rotating motor 302 can drive the hydraulic telescopic rod 205 to rotate, thereby driving the lifting ventilation plate 206 to rotate, so as to facilitate the movement and heating of the steel balls on the lifting ventilation plate 206.

The support platform 402 on the lower base plate 401 can support and fix the heating cylinder 1 at a suitable height, so that the tempering device can be used to temper the steel ball.

[0033] Please refer to this carefully. Figure 1 and Figure 2 A water storage cooling tank 403 is fixedly connected to the upper surface of the bottom plate 401. The upper surface of the water storage cooling tank 403 is fixedly connected to the outer surface of the conveying pipe 201. Cooling water is manually transported into the water storage cooling tank 403 to cool the heated steel ball, thus facilitating the use of the tempering device.

[0034] Please refer to this carefully. Figure 2 A switch valve 404 is fixedly connected to the outer surface of the water storage cooling tank 403. The output end of the switch valve 404 is fixedly connected to a drain pipe 405. By manually opening the switch valve 404, the cooling water in the water storage cooling tank 403 can be easily discharged through the drain pipe 405, thereby facilitating the replacement of the cooling water in the water storage cooling tank 403.

[0035] When using this utility model: First, connect the heating jacket 202, hydraulic telescopic rod 205, rotating motor 302 and conveying motor 5 to the power supply. When it is necessary to use this high-efficiency tempering device to temper the wear-resistant steel ball, first manually place the tempering device on a horizontal ground. The lower base plate 401 of the tempering device can be used to stably fix it in the required position, so that the tempering device can stably temper the wear-resistant steel ball.

[0036] Next, water for cooling the heat-resistant steel balls is manually added to the water storage cooling tank 403. By controlling the power supply of the heating sleeve 202 fixed outside the heating cylinder 1, heat can be generated by the heating sleeve 202 to heat the inside of the heating cylinder 1. By controlling the power supply of the conveying motor 5 fixed on one side of the conveying pipe 201, the conveying motor 5 can drive the rotating rod 6 to rotate the spiral blade 7 inside the conveying pipe 201. The steel balls that need to be tempered are manually conveyed from the feeding hopper 207 into the conveying pipe 201. The rotation of the spiral blade 7 facilitates the conveying of the steel balls to the lifting ventilation plate 206 sliding inside the heating cylinder 1 until a certain amount of steel balls can be conveyed onto the lifting ventilation plate 206.

[0037] By controlling the power supply of the hydraulic telescopic rod 205, the lifting ventilation plate 206 can be driven to slide inside the heating cylinder 1 until it can lift multiple steel balls to the upper part of the heating cylinder 1, thereby using the hot air inside the heating cylinder 1 to heat the steel balls. At the same time, by controlling the power supply of the rotating motor 302, the hydraulic telescopic rod 205 can be driven to rotate inside the heating cylinder 1, thereby using the friction of the steel balls on the lifting ventilation plate 206 to make multiple steel balls rotate inside the heating cylinder 1, thereby making multiple steel balls evenly heated inside the heating cylinder 1.

[0038] After the steel balls are heated, the hydraulic telescopic rod 205 drives the lifting ventilation plate 206 to descend to the bottom of the heating cylinder 1. The rotating motor 302 drives the lifting ventilation plate 206 to rotate, and the conveying motor 5 outputs power in the opposite direction, causing the rotating rod 6 to rotate in the opposite direction. This allows the steel balls to be conveyed to the other end under the action of the rotating spiral blades 7 in the conveying pipe 201, until the steel balls are conveyed to the water storage cooling tank 403 and dropped into the water storage cooling tank 403 for cooling, thereby completing the tempering process of the wear-resistant steel balls.
