Description

Technical Field

[0001] The invention relates to the technical field of quenching devices, in particular to a quenching device for machining mechanical castings. Background Art

[0002] The quenching device in mechanical casting processing is a device used to quickly cool castings or metal workpieces during the heat treatment process (usually in a cooling medium such as water, oil, air, etc.) to achieve a hardening effect. Quenching is a heat treatment process that increases the hardness, strength and wear resistance of high-temperature metal by rapidly cooling it. The main function of the quenching device is to provide an environment for controlling the cooling process, ensuring that the metal can be evenly stressed during the rapid cooling process and avoiding cracks or deformation caused by thermal stress.

[0003] For example, the "A quenching device for machining mechanical castings" with publication number CN218666155U comprises a quenching box, a feeding device is provided above the quenching box, the feeding device comprises a box body, the outer wall of the box body is fixedly connected to the quenching box, the output shaft of the first motor is fixedly connected to the second slide, one end of the first slide passes through the box body, one end of the second slide passes through the box body, and one end of the second slide is located above the feed port, through the cooperation of the quenching box and the discharging device, the second motor drives the discharging wheel to rotate, and then the discharging wheel places the mechanical castings on the conveyor belt, reducing the time for workers to take out the quenched mechanical castings and reducing the time required for work, through the cooperation of the quenching box and the feeding device, the first motor drives the second slide to rotate, and then the first motor reverses, avoiding contact when workers put high-temperature mechanical castings into the quenching box, reducing the danger of quenching work.

[0004] However, in the prior art, although this type of quenching device can prevent workers from putting high-temperature mechanical castings into the quenching box and contact with them, thereby reducing the danger of quenching work, it is lacking in preventing the mechanical castings from sticking. When this type of quenching device is used to transport mechanical castings, the mechanical castings are injected into the quenching box through a slide, and the mechanical castings are stuck together. This not only makes it impossible to control the orderly entry of the mechanical castings into the quenching box, thereby causing the feed port to be blocked, but also during the cooling process, the surface of the casting will harden rapidly, especially the surface of the steel. The contact surface between the castings may cause the surface hardened layers to stick to each other, thereby causing the castings to stick.

[0005] Therefore, we propose a quenching device for mechanical casting processing to solve the above-mentioned problems. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When in use, the motor A drives the gear A to rotate. When the gear A rotates, it drives the limit gear B and the gear C to rotate through the tooth chain. When the gear C rotates, it drives the connecting rod A to rotate. When the connecting rod A rotates, it rotates the fixed rod and the connecting rod B, thereby driving the rotating rod A to rotate inside the placement rack. At this time, the fixed rod drives the rotating rack to swing upward, thereby driving the guide rack C to swing upward. At this time, the guide rack C will push up the mechanical casting on the guide rack B through the card slot. With the continuous rotation of the gear C, the guide rack C will also gradually move downward. At this time, the mechanical casting on the guide rack C will fall back into the card slot of the guide rack B, so that the mechanical casting moves to the guide rack A in turn, and finally guides the feed port through the guide rack A, and enters the quenching box through the feed port for quenching, thereby avoiding the situation that the mechanical castings stick or block the feed port due to the inability to control the orderly entry of the mechanical castings into the quenching box when conveying the mechanical castings;

[0019] 2. When in use, the quenched mechanical casting is guided to the chain conveyor belt through the guide block. At this time, turn on the motor B, which will drive the driving shaft to rotate, so that the chain conveyor belt rotates on the surface of the driving shaft and the driven shaft, and the chain conveyor belt will drive the grab hook to move upward, thereby driving the mechanical casting to move upward. After the mechanical casting is driven to the top of the chain conveyor belt by the grab hook, the grab hook will flip the mechanical casting, so that the mechanical casting falls on the guide plate A, and the guide plate A will guide the mechanical casting to the guide plate B, and the guide plate will be turned over. Plate B will rotate downwards after receiving pressure, and at this time, the guide plate B will rotate upwards under the torsion of the torsion spring, thereby unloading the force when the mechanical casting falls, and finally guiding the mechanical casting to the conveyor rack, which then transports the mechanical casting after quenching, preventing the mechanical casting from colliding with other parts when falling and causing damage to it, and at the same time avoiding the quenching liquid in the quenching box from flowing out of the quenching box when taking out the mechanical casting, thereby effectively reducing the use of quenching liquid;

[0020] 3. When in use, the quenching liquid is filtered through the filter plate, so as to collect the metal slag in the quenching liquid. When the metal slag needs to be taken out, the fixed block only needs to be pulled outward. After the fixed block slides out of the fixed groove, the fixed block can be rotated. After the fixed block is turned away from the surface of the fixed plate, the filter plate can be pulled out of the quenching box through the fixed plate, so as to take out the metal slag in the filter plate. After taking out the metal slag, the filter plate is inserted into the quenching box again. At this time, the sealing gasket will be inserted into the sealing groove. After the sealing gasket is inserted into the sealing groove, the fixed block is pulled outward again. After the fixed block is away from the fixed plate, the fixed block can be rotated. After the fixed block is rotated to the fixed groove, the fixed block can be released. At this time, the fixed block will slide into the fixed groove due to the tension of the tension spring. After the fixed block is inserted into the fixed groove, the fixing of the fixed plate can be completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In this embodiment, the motor A109 drives the gear A110 to rotate. When the gear A110 rotates, it drives the limit gear B111 and the gear C112 to rotate through the toothed chain 113. When the gear C112 rotates, it drives the connecting rod A114 to rotate. When the connecting rod A114 rotates, it drives the fixed rod 115 and the connecting rod B117 to rotate, thereby driving the rotating rod A116 to rotate inside the placement rack 106.

The driving shaft 204 is rotatably connected to the quenching box 100, and the grab hook 207 is slidably connected to the sliding groove 209. One end of the torsion spring 211 is connected to the side of the material guide plate B212, and the other end is connected to the inner surface of the quenching box 100.

[0035] In this embodiment, the quenched mechanical casting is guided to the chain conveyor 206 by the guide block 200. At this time, the motor B203 is turned on, and the motor B203 drives the driving shaft 204 to rotate, so that the chain conveyor 206 rotates on the surfaces of the driving shaft 204 and the driven shaft 205, and the chain conveyor 206 drives the grab hook 207 to move upward, thereby driving the mechanical casting to move upward. After the mechanical casting is driven to the top of the chain conveyor 206 by the grab hook 207, the grab hook 207 will flip the mechanical casting, so that the mechanical casting falls on the guide plate A208, and the guide plate A208 will turn the mechanical casting At the guide plate B212, the guide plate B212 will rotate downward after being subjected to pressure, and at this time the guide plate B212 will be subjected to the torsion force of the torsion spring 211 and rotate upward, thereby unloading the force when the mechanical casting falls, and finally guiding the mechanical casting to the conveying rack 201, and then the conveying rack 201 transports the mechanical casting after quenching, thereby preventing the mechanical casting from colliding with other parts when falling and causing damage to it, and at the same time avoiding the quenching liquid in the quenching box 100 from flowing out of the quenching box 100 when taking out the mechanical casting, thereby effectively reducing the use of quenching liquid.

[0036] Embodiment 3: According to Figure 7-8As shown, a drain pipe 300 is fixedly installed on the surface of the quenching box 100, a sealing groove 301 is opened on the side of the quenching box 100, a filter plate 302 is inserted inside the quenching box 100, a fixing plate 303 is fixedly installed on the surface of the filter plate 302, a fixing groove 304 is opened on the surface of the fixing plate 303, a sealing gasket 305 is fixedly installed on the surface of the fixing plate 303, a sliding rod 306 is slidably connected inside the quenching box 100, a tension spring 307 is sleeved on the surface of the sliding rod 306, a fixing block 308 is fixedly installed on the surface of the sliding rod 306, the filter plate 302 is slidably connected to the quenching box 100, the sealing gasket 305 is slidably connected to the sealing groove 301, the material of the sealing gasket 305 is natural rubber, one end of the tension spring 307 is connected to the surface of the fixing block 308, and the other end is connected to the inner surface of the quenching box 100, and the fixing block 308 is slidably connected to the fixing groove 304.

[0037] In this embodiment, the quenching liquid is filtered through the filter plate 302, so that the metal slag in the quenching liquid is collected. When the metal slag needs to be removed, the fixing block 308 only needs to be pulled outward, and the fixing block 308 can be rotated after the fixing block 308 slides out of the fixing groove 304. After the fixing block 308 is turned away from the surface of the fixing plate 303, the filter plate 302 can be pulled out from the quenching box 100 through the fixing plate 303, so that the metal slag in the filter plate 302 is removed. After the metal slag is removed, the filter plate 302 is inserted into the quenching box 100. 00, at this time, the sealing gasket 305 will be inserted into the sealing groove 301. After the sealing gasket 305 is inserted into the sealing groove 301, the fixing block 308 will be pulled outward. After the fixing block 308 is away from the fixing plate 303, the fixing block 308 can be rotated. After the fixing block 308 is rotated to the fixing groove 304, the fixing block 308 can be released. At this time, the fixing block 308 will be subjected to the pulling force of the tension spring 307 and slide into the fixing groove 304. After the fixing block 308 is inserted into the fixing groove 304, the fixing of the fixing plate 303 is completed.

[0038] The use method and working principle of this device: when it is necessary to transport the mechanical castings to the quenching box 100, it is only necessary to turn on the motor A109 first, and the motor A109 will drive the gear A110 to rotate. When the gear A110 rotates, it will drive the limit gear B111 and the gear C112 to rotate through the tooth chain 113, and the gear C112 will drive the connecting rod A114 to rotate when it rotates. When the connecting rod A114 rotates, the fixed rod 115 and the connecting rod B117 will rotate, thereby driving the rotating rod A116 to rotate inside the placement rack 106. At this time, the fixed rod 115 will drive the rotating rack 118 to swing upward, thereby driving the guide rack C119 to swing upward. At this time, the guide rack 119 is rotated. The material rack C119 will lift up the mechanical casting on the guide rack B108 through the slot 101. As the gear C112 rotates continuously, the guide rack C119 will gradually move downward. At this time, the mechanical casting on the guide rack C119 will fall back into the slot 101 of the guide rack B108, so that the mechanical casting moves to the guide rack A105 in turn, and finally guides the feed port 104 through the guide rack A105, and enters the quenching box 100 through the feed port 104 for quenching, thereby avoiding the situation that the mechanical casting sticks or blocks the feed port 104 due to the inability to control the mechanical casting to enter the quenching box 100 in an orderly manner when conveying the mechanical casting;

[0039] When the quenching liquid needs to be injected into the quenching box 100, the quenching liquid can be injected into the quenching box 100 only through the water inlet pipe 120. When the mechanical casting is continuously moved, the groove on the guide rack B108 will be worn. When the guide rack B108 needs to be replaced, the insert 107 can be rotated. After the insert 107 is rotated out of the guide rack B108, it can be removed from the placement rack 106, and then a new guide rack B108 is placed on the placement rack 106, and then the insert 107 is connected to the guide rack B108 through a thread to complete the replacement of the guide rack B108.

[0040] When the mechanical casting after quenching needs to be led out of the quenching box 100, it is only necessary to guide the quenched mechanical casting to the chain conveyor 206 through the guide block 200. At this time, the motor B203 is turned on, and the motor B203 will drive the driving shaft 204 to rotate, so that the chain conveyor 206 rotates on the surface of the driving shaft 204 and the driven shaft 205, and the chain conveyor 206 will drive the grab hook 207 to move upward, thereby driving the mechanical casting to move upward. After the mechanical casting is driven to the top of the chain conveyor 206 by the grab hook 207, the grab hook 207 will flip the mechanical casting, so that the mechanical casting falls on the guide plate A208, and the guide plate A208 will guide the mechanical casting to the guide plate B212. The guide plate B212 will rotate downward after being subjected to pressure. At this time, the guide plate B212 will be subjected to the torsion force of the torsion spring 211 and rotate upward, thereby unloading the force when the mechanical casting falls. Finally, the mechanical casting is guided to the conveying rack 201, and then the conveying rack 201 conveys the mechanical casting after quenching, thereby preventing the mechanical casting from colliding with other parts when falling and causing damage to the mechanical casting. At the same time, it also prevents the quenching liquid in the quenching box 100 from flowing out of the quenching box 100 when the mechanical casting is taken out, thereby effectively reducing the use of the quenching liquid.

[0041] When it is necessary to collect the metal slag, the quenching liquid only needs to be filtered through the filter plate 302, so as to collect the metal slag in the quenching liquid. When it is necessary to remove the metal slag, the fixing block 308 only needs to be pulled outward, and the fixing block 308 can be rotated after it slides out of the fixing groove 304. After the fixing block 308 is rotated away from the surface of the fixing plate 303, the filter plate 302 can be pulled out of the quenching box 100 through the fixing plate 303, so as to remove the metal slag in the filter plate 302. After removing the metal slag, the filter plate 302 can be inserted into the quenching box 100 again. In the quenching box 100, the sealing gasket 305 will be inserted into the sealing groove 301. After the sealing gasket 305 is inserted into the sealing groove 301, the fixing block 308 will be pulled outward. After the fixing block 308 is away from the fixing plate 303, the fixing block 308 can be rotated. After the fixing block 308 is rotated to the fixing groove 304, the fixing block 308 can be released. At this time, the fixing block 308 will be subjected to the tension of the tension spring 307 and slide into the fixing groove 304. After the fixing block 308 is inserted into the fixing groove 304, the fixing of the fixing plate 303 can be completed.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
