Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal fastener quenching technology, specifically to a metal fastener end quenching device. Background Technology
[0002] Metal fasteners are components used to connect, fix, and assemble two or more parts. They achieve mechanical connections through threads, snaps, riveting, etc., and are indispensable basic components in fields such as machinery, construction, electronics, automobiles, and aerospace. End hardening can improve the hardness and wear resistance of metal fasteners.
[0003] According to Chinese Patent Publication No. CN219637261U, "A Metal Fastener End Quenching Device", it mainly describes a method that uses two nozzles to simultaneously quench both ends of the fastener after it is installed in the placement table. This avoids quenching the ends of the fastener separately, thus shortening the quenching time for both ends, reducing the number of operation steps, and improving quenching efficiency. Furthermore, by pressing the fastener into the placement table, the clamping component automatically clamps the fastener, further reducing operation steps and making the operation more convenient.
[0004] Common metal fasteners require pre-cooling after end quenching before entering the cooling medium. Pre-cooling quenching reduces quenching stress and distortion in the workpiece, improving machining accuracy and service life. Clamping the metal fastener with a fixture facilitates quenching both ends. However, in actual operation, clamping the metal fastener with a fixture by pressing it individually and then bringing it close to the quenching structure reduces machining efficiency and generates high-temperature steam during quenching, affecting machining safety.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] Please refer to the following: Figure 1-3The device for end quenching of metal fasteners shown includes a fixed plate 1, of which two are provided. Two first motors are fixedly connected to the fixed plate 1. The first motors drive drive rollers 2 to rotate, which, in conjunction with connecting rollers 3, causes a conveyor belt 4 to rotate. The output end of the first motor is fixedly connected to the drive rollers 2, and the conveyor belt 4 is sleeved on the drive rollers 2. One side of the conveyor belt 4 contacts the connecting roller 3. Lower clamping blocks 5 are evenly fixedly connected to one of the conveyor belts 4. One side of the lower clamping block 5 contacts an upper clamping block 6. Limiting grooves are provided on the opposite sides of the upper clamping block 6 and the lower clamping block 5, thereby limiting the movement of the lower clamping block 6. The slot limits the metal fastener, and then, with the cooperation of the conveyor belt 4, the metal fastener moves downward. The upper clamping block 6 is evenly fixedly connected to another conveyor belt 4. The upper side of the fixed plate 1 is fixedly connected to the guide plate 7, which provides guidance for the metal fastener. The fixed plate 1 has a first groove 8. The fixed plate 1 is fixedly connected to one side of the first groove 8 by an electric push rod 9. The electric push rod 9 drives the moving plate 10 to move, which can calibrate both ends of the metal fastener. The output end of the electric push rod 9 is fixedly connected to the moving plate 10. A heating ring 11 is fixedly connected to one side of the moving plate 10 for heating. Ring 11 is a spiral heating wire. Heating ring 11 is connected to an external power supply via a wire. A second groove 12 is provided on the bottom side of fixing plate 1. A water pump 13 is fixedly connected to one side of the second groove 12 on fixing plate 1. The water pump 13 is connected to external quenching liquid and draws the quenching liquid into output pipe 14 and water distribution ring 15. The liquid is then sprayed onto both ends of the metal fastener through nozzle 16, thus completing the quenching process. Simultaneously, as the metal fastener moves from the center of fixing plate 1 to the bottom side of fixing plate 1, a pre-cooling structure is formed, reducing the probability of end cracking. An output device is fixedly connected to the output end of water pump 13. Pipe 14, one end of which is fixedly connected to a water distribution ring 15. Spray nozzles 16 are evenly fixedly connected to the water distribution ring 15. A third groove is formed between the first groove 8 and the second groove 12 on the fixing plate 1. A bracket is fixedly connected in the third groove. A guide fan 24 is rotatably connected to the bracket. An air guide pipe 25 is fixedly connected to the fixing plate 1 at the third groove. The guide fan 24 leads the steam out from the third groove and moves it out through the air guide pipe 25. Through a specially designed guiding structure, a warning sign can be set on the air guide pipe 25 to reduce the harm of high temperature steam to personnel.
[0018] The upper side of the fixing plate 1 has a fourth groove 17. The fixing plate 1 is fixedly connected to an electric telescopic rod 18 on one side of the fourth groove 17. The output end of the electric telescopic rod 18 is fixedly connected to a push plate 19. The electric telescopic rod 18 drives the push plate 19 to provide position calibration on both sides of the metal fastener, so that the correspondence between the metal fastener and the heating ring 11 is more accurate.
[0019] Among them, a limiting roller 20 is fixedly connected to one side of the fixed plate 1. The limiting roller 20 is in contact with the conveyor belt 4. By setting the limiting roller 20, the stability of the rotation of the conveyor belt 4 can be further increased.
[0020] One side of the conveyor belt 4 is in contact with a pad 21, which is fixedly connected to the fixed plate 1. By setting the pad 21, which corresponds to the three processing structures, the stability of the upper clamping block 6 and the lower clamping block 5 in the processing position can be increased.
[0021] The bottom side of the fixed plate 1 is fixedly connected to a guide frame 22, and the top side of the guide frame 22 is fixedly connected to a filter screen 23. By setting the guide frame 22 and the filter screen 23, the cooling water can be guided.
[0022] Working principle: The metal fastener enters between the two conveyor belts 4 from the guide plate 7, and is then supported by the lower clamping block 5 and limited by the upper clamping block 6. The electric telescopic rod 18 and the push plate 19 provide position calibration, and the metal fastener moves down under the action of the drive motor. Then, the electric push rod 9 drives the moving plate 10 to move, and causes the heating ring 11 to engage with the end of the metal fastener. After heating is completed, the metal fastener moves down, and the water distribution ring 15 and the nozzle 16 spray water to guide the end of the metal fastener. The high-temperature steam generated in this process can be guided to a specific location through the guide fan 24 and the air guide pipe 25, thereby reducing the danger of high-temperature steam to the environment. The whole process can be batch quenched, improving quenching efficiency.
[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
