Description

Technical Field

[0001] This utility model relates to the technical field of batch quenching devices for pins, and in particular to a batch quenching device for pins. Background Technology

[0002] In the prior art, such as the patent number CN222455139U, there is a batch quenching device for pin shafts. Although it achieves the effect of batch quenching of pin shafts, it adopts the water spray quenching method. The water flow can easily damage the high-frequency heating equipment, which reduces the quenching efficiency due to the frequent replacement of the high-frequency heating equipment. Utility Model Content

[0003] Therefore, it is necessary to provide a batch quenching device for pin shafts to address the technical problem of low efficiency caused by the easy damage of the aforementioned components.

[0004] To achieve the above objectives, this utility model provides a batch quenching device for pin shafts, including a frame and pin shafts. Several linear actuators are mounted on the frame, and a U-shaped frame is mounted on the output end of each linear actuator. A high-frequency heating coil is mounted on the U-shaped frame. A driven block is mounted on the frame, and a limiting mechanism for limiting the driven block is provided at the bottom of the U-shaped frame. A water spray ring is mounted on the driven block, and several downward-sloping water spray heads are provided on the water spray ring. An annular baffle is mounted above the water spray ring. A fan is mounted on the driven block, and a conductive plate I connected to an external power source is mounted on the U-shaped frame. A conductive plate II electrically connected to the fan is mounted inside the driven block.

[0005] Preferably, the limiting mechanism includes a slot, which is located on both sides of the bottom of the U-shaped frame. A locking block is slidably engaged in the slot, and a spring is installed in the slot. The output end of the spring is connected to the locking block.

[0006] Preferably, a second linear actuator is installed on the frame, and a pusher is installed at the output end of the second linear actuator. The pusher can be inserted into the driven block to squeeze out the block.

[0007] Preferably, the card block is provided with a chamfer that cooperates with the driven block and the push frame.

[0008] Preferably, the fans are symmetrically arranged around the pivot pin, and the fan outlets are deflected toward the pivot pin.

[0009] Preferably, a fixed frame is installed on the driven block, and the water spray ring, annular baffle and fan are all installed on the fixed frame.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: By using a combination of downward-sloping water nozzles, a fan, and an annular baffle, water is less likely to splash onto the high-frequency heating coil during water quenching, thus avoiding frequent replacements and reducing production efficiency. By setting up a limiting mechanism, the high-frequency heating coil can be set separately from the water spray ring, and the water spray ring is placed below the high-frequency heating coil. This reduces the impact of water vapor that may remain on the water spray ring on the high-frequency heating coil, further preventing damage to the high-frequency heating coil and improving production efficiency.

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 3This application provides a batch quenching device for pin shafts, including a frame 1 and pin shafts 2. The pin shafts 2 can be mechanically or manually fed and threaded using existing technology. The top shaft and the fixed bottom shaft are pressed and fixed together. When the pin shafts 2 are installed, the high-frequency heating coils 5 and water spray rings 7 can be located on the upper and lower sides of the pin shafts 2 respectively, so as not to affect their placement and fixation. Several linear actuators 3 are fixedly installed on the frame 1. The linear actuators 3 can be electric cylinders. A U-shaped frame 4 is fixedly installed at the output end of the linear actuators 3. The high-frequency heating coils 5 are fixedly installed on the U-shaped frame 4. The high-frequency heating coils 5 are existing technology and are connected to a high-frequency heating device with an external power supply. A driven block 6 is placed on the frame 1. The bottom of the U-shaped frame 4 is provided with a limiting mechanism to limit the driven block 6. A driven block 6 is fixedly installed. The machine includes a water spray ring 7, whose output end is connected to a low-temperature water source and water pump via a retractable hose. Several downward-sloping water spray heads 8 are provided on the water spray ring 7. An annular baffle 9 is fixedly installed above the water spray ring 7, with its inner ring fitting a clearance fit with the pin 2. A fan 10 is fixedly installed on the driven block 6. A conductive plate 11, electrically connected to an external power source, is fixedly installed on the U-shaped frame 4. A conductive plate 12, electrically connected to the fan 10, is fixedly installed inside the driven block 6. Redundant power lines can be configured to facilitate lifting and lowering of the U-shaped frame 4 and the driven block 6. A water tank for receiving quenching water is located at the bottom of the frame 1. To prevent damage to the high-frequency heating coil 5, the water needs to be drained and cleaned promptly. The linear actuator 3, high-frequency heating equipment, and water pump supplying the water spray ring 7 can all be connected via an external signal processor.

[0014] In this embodiment, after the pin 2 is placed and fixed on the frame 1, the linear actuator 3 drives the U-shaped frame 4 and the high-frequency heating coil 5 mounted on it to move downwards for heating. When the pin 2 is heated to its lowest point, the U-shaped frame 4 can be locked together with the driven block 6 by the limiting mechanism. At this time, the high-frequency heating coil 5 can stop heating, and the water spray ring 7 can be used for quenching and cooling through the water spray head 8. During quenching, the linear actuator 3 can drive the U-shaped frame 4 and the driven block 6 to move upwards, so that the downward spray of water from the inclined downward water spray head 8 and the gradual upward movement of the water spray ring 7 for quenching make it difficult for water to splash onto the high-frequency heating coil 5. The flow of water can be further limited by the blocking effect of the annular baffle 9. When the U-shaped frame 4 and the driven block 6 are engaged, the conductive sheet 11 can abut against the conductive sheet 12 and be energized, so that the fan 10 can be connected to the external power supply to blow air. Thus, after the quenching and cooling is completed, as the U-shaped frame 4 and the driven block 6 gradually descend, the fan 10 can continuously blow off the water droplets remaining on the pin 2, which facilitates the pin 2 to proceed to the next process. At the same time, it further makes it less likely for water vapor to stick to the high-frequency heating coil 5, thereby avoiding the need for replacement of quenched parts and further improving the efficiency of batch quenching of the pin.

[0015] In some embodiments, to facilitate the interlocking and limiting of the U-shaped frame 4 and the driven block 6, a limiting mechanism is provided, including a slot 13. The slot 13 is symmetrically arranged on both sides of the bottom of the U-shaped frame 4. A locking block 14 is slidably engaged within the slot 13. A spring 15 is fixedly installed within the slot 13, and the output end of the spring 15 is connected to the locking block 14. By pressing the spring 15 with the locking block 14, it can extend and retract within the slot 13, thereby locking the locking block 14 within the driven block 6.

[0016] In some embodiments, to facilitate the separation of the U-shaped frame 4 from the driven block 6, a linear actuator 2 16 is fixedly mounted on the frame 1. The linear actuator 2 16 can be connected to an external signal processor. A pusher 17 is fixedly mounted on the output end of the linear actuator 2 16. The pusher 17 can be inserted into the driven block 6 to squeeze out the locking block 14. After the linear actuator 2 16 drives the pusher 17 to squeeze out the locking block 14, it moves forward so that the pusher 17 cooperates with the frame 1 to squeeze and fix the driven block 6. Therefore, when the U-shaped frame 4 moves upward to reset, it will not drive the driven block 6 upward together.

[0017] In some embodiments, to enable the locking block 14 to be engaged with the driven block 6 and the pusher 17 to push the locking block 14 out, the locking block 14 is provided with a chamfer that cooperates with the driven block 6 and the pusher 17. The bottom chamfer of the locking block 14 facilitates the collision and retraction of the locking block 14 with the driven block 6, thereby allowing it to be engaged inside the driven block 6. The side chamfer of the locking block 14 facilitates the pusher 17 to press it and retract it.

[0018] In some embodiments, to improve the efficiency of the fan 10 in blowing off residual water on the pin 2, the fan 10 is arranged symmetrically around the pin 2, and the air outlet of the fan 10 is deflected toward the pin 2.

[0019] In some embodiments, to facilitate the installation and fixing of the water spray ring 7, the annular baffle 9, and the fan 10, a fixing bracket 18 is fixedly installed on the driven block 6, and the water spray ring 7, the annular baffle 9, and the fan 10 are all fixedly installed on the fixing bracket 18.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0021] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0022] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
