Description
Technical Field
[0001] The utility model relates to the technical field of ultra-thin-wall shuttle tube processing, in particular to an ultra-thin-wall shuttle tube quenching device. Background Art
[0002] Metal javelin is a commonly used sports equipment in throwing track and field events. It consists of a metal spear head and a metal spear body. The spear body is usually made of an ultra-thin wall shuttle tube.
[0003] The ultra-thin-wall shuttle tube is a metal tube that is shuttle-shaped as a whole, which makes the ultra-thin-wall shuttle tube have the characteristics of inconsistent tube diameters. In addition, since the ultra-thin-wall shuttle tube is processed and formed by a tube shrinking machine, the tube shrinking machine cannot ensure the consistency of the overall wall thickness of the shuttle tube during the process of shrinking the tube into a shuttle tube, resulting in inconsistent wall thicknesses of various sections of the shuttle tube.
[0004] In the processing of ultra-thin-wall shuttle tubes, quenching is an important process. At present, the quenching process of ultra-thin-wall shuttle tubes is as follows: the ultra-thin-wall shuttle tubes are placed horizontally on the conveyor roller, and the conveyor roller drives the ultra-thin-wall shuttle tubes horizontally into the induction heating coil at a fixed speed for heating, and then the heated ultra-thin-wall shuttle tubes are spray-cooled to complete the quenching.
[0005] The quenching process currently used has the following disadvantages: (1) Due to the different diameters of shuttle tubes, flat heating can easily cause the tubes to bend and deform, affecting product quality; (2) Since the conveying roller has a fixed conveying speed for ultra-thin-wall shuttle tubes, the time it takes for each section of the ultra-thin-wall shuttle tube to pass through the induction heating coil is the same. Since the wall thickness of each section of the ultra-thin-wall shuttle tube is inconsistent, this can easily lead to uneven heating temperatures of each section of the shuttle tube, resulting in poor quenching effect of the shuttle tube. The hardness of the shuttle tube after quenching can only reach HRC35, and the quenching uniformity can only reach 50%. The quenching uniformity refers to measuring the hardness of each point at 20 points evenly distributed along the length of the index gun, and the percentage of the number of points with the required hardness in the total number.

The obtained shuttle tube product does not need to be cut or trimmed, and can be directly welded to the rear gun head. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, the structure of the shuttle tube clamp 4 includes: a high temperature resistant and insulated clamp body 41, which is made of ceramic in actual production; an axial tapered channel 42 with a diameter gradually increasing from top to bottom is provided in the clamp body 41, and the axial tapered channel 42 penetrates downward to the lower end surface of the clamp body 41 to form a channel insertion opening 43 for inserting the end of the shuttle tube 5 into the axial tapered channel 42, and a radial threaded lock hole 44 penetrating to the axial tapered channel 42 is also provided on the outer wall of the clamp body 41.

The shuttle tube clamp has a simple structure and is easy to disassemble and maintain. In this embodiment, a PLC controller 26 is also included. The PLC controller 26 is electrically connected to the shuttle tube rotation servo motor 2, the shuttle tube lifting servo motor 13, the pneumatic rotary chuck 3, the laser infrared thermometer 10 and the chiller 7. The PLC controller 26 automatically controls each device, thereby improving the use efficiency.
[0031] The quenching process of the ultra-thin wall shuttle tube of the utility model is as follows:
[0032] (1) Material preparation: Before quenching, a section of tail pipe 51 is reserved at one end of the shuttle tube 51 during the forming process;
[0033] (2) inserting the upper end of the shuttle tube clamp 4 into the pneumatic rotary chuck 3, and causing the PLC controller 26 to control the pneumatic rotary chuck 3 to clamp the shuttle tube clamp 4;
[0034] (3) Before quenching, the shuttle tube clamp 4 clamps the tail tube according to the length to be cut. The specific operation of the shuttle tube clamp 4 clamping the shuttle tube 5 is: inserting the tail tube 51 to be cut of the shuttle tube 5 upward into the axial tapered channel 42 of the shuttle tube clamp 4, and then tightening the threaded locking column 45 inwardly so that the threaded locking column 45 presses the tail tube 51 of the shuttle tube 5 inwardly, thereby completing the clamping and fixing of the shuttle tube 5 by the shuttle tube clamp 4;
[0035] (4) The PLC controller 26 controls the start of the shuttle tube lifting servo motor 13, so that the shuttle tube lifting servo motor 13 drives the sliding bracket 1 to move downward toward the induction heating coil 8 along the linear guide rail 18 through the cooperation of the active synchronous pulley 114, the synchronous belt 17 and the driven synchronous pulley 16, and simultaneously drives the shuttle tube 5 to move downward toward the induction heating coil 8; while the shuttle tube 5 moves downward, the PLC controller 26 simultaneously starts the shuttle tube rotation servo motor 2, so that the shuttle tube rotation servo motor 2 drives the shuttle tube 5 to rotate through the pneumatic rotating chuck 3 and the shuttle tube clamp 4;
[0036] (5) After the lower end of the shuttle tube 5 is inserted into the induction heating coil 8, the PLC controller 26 stops the servo motor 13 for lifting the shuttle tube, so that the shuttle tube 5 stops descending; then the high-frequency induction heater 9 controls the induction heating coil 8 to heat the shuttle tube section inserted into the induction heating coil 8. During the process of the induction heating coil 8 heating the shuttle tube 5, the shuttle tube 5 is always kept rotating, so that the shuttle tube 5 is heated while rotating. At the same time, the laser infrared thermometer 10 monitors the temperature of the shuttle tube section heated by the induction heating coil 8 in real time, and feeds back the temperature information to the PLC controller 26 in real time. The temperature measurement point of the laser infrared thermometer 10 is the shuttle tube section located at the entrance section of the heating channel after the shuttle tube is inserted into the heating channel of the induction heating coil 8. The length of the shuttle tube section corresponding to the temperature measurement point of the laser infrared thermometer is defined as h. Since the induction heating coil is heated by the current effect, the magnetism is generated, and the induction coil is heated to achieve the heating effect, and the heating is uniform, so the heating effect of different positions in the induction heating coil is the same;
[0037] (6) When the PLC controller 26 learns that the temperature of the shuttle tube section heated by the induction heating coil 8 reaches a preset 820°C based on the temperature information fed back by the laser infrared thermometer 10, the PLC controller 26 restarts the shuttle tube lifting servo motor 13, drives the shuttle tube 5 to move downward a distance h again through the sliding bracket 1, and then stops the shuttle tube lifting servo motor 13 again, causing the shuttle tube 5 to stop descending again;
[0038] (7) Then the induction heating coil 8 continues to heat the shuttle tube section extending into the induction heating coil 8. While the induction heating coil 8 heats the shuttle tube 5, the shuttle tube 5 continues to rotate, so that the shuttle tube 5 continues to rotate and be heated; at the same time, the laser infrared thermometer 10 continues to monitor the temperature of the shuttle tube section at the entrance section of the heating channel of the induction heating coil 8 in real time, and feeds back the temperature information to the PLC controller 26 in real time; when the PLC controller 26 knows that the temperature of the shuttle tube section heated by the induction heating coil 8 reaches a preset 820°C based on the temperature information fed back by the laser infrared thermometer 10, the PLC controller 26 restarts the shuttle tube lifting servo motor 13 again, drives the shuttle tube 5 to move downward a distance h again through the sliding bracket 1, and then stops the shuttle tube lifting servo motor 13 again, so that the shuttle tube 5 stops descending again;
[0039] (8) Repeat step (7) until all the sections of the shuttle tube are heated; as the shuttle tube is continuously moved downward, the sections of the shuttle tube heated to the preset temperature are continuously inserted downward into the water tank 6 for cooling until all the sections of the shuttle tube exposed outside the shuttle tube clamp 4 are quenched;
[0040] When the shuttle tube 5 is quenched, a clear dividing line is formed between the quenched tube section of the shuttle tube and the unquenched tube section clamped by the shuttle tube clamp, and then the shuttle tube is cut along the dividing line, and the unquenched tube section clamped by the shuttle tube clamp is cut off, thereby obtaining a quenched ultra-thin-wall shuttle tube finished product consistent with the standard length of the javelin gun body;
[0041] During the entire quenching process of the shuttle tube, the water temperature sensor of the chiller 7 will monitor the water temperature of the water tank 6 in real time, and will feed back the water temperature information to the PLC controller 26 in real time. When the PLC controller 26 knows that the water temperature of the water tank 6 reaches 50°C based on the water temperature information fed back by the water temperature sensor, the PLC controller 26 will start the chiller 7. After the chiller 7 is started, it will cool the water in the water tank 6. By controlling the temperature of the water in the water tank in real time, the consistency of the water temperature in the water tank during the entire quenching process of the shuttle tube is guaranteed, thereby ensuring the quenching effect. According to testing, the hardness of the shuttle tube after quenching can reach HRC45, and the quenching uniformity can be guaranteed to be above 90%.
[0042] The advantages of the utility model are: (1) the shuttle tube is in a vertical upright position during the entire quenching process, which can effectively prevent the shuttle tube from bending and deforming, thereby ensuring product quality; (2) since the wall thickness of each section of the shuttle tube is inconsistent and the shuttle tube is an ultra-thin wall tube, it is impossible to accurately measure the wall thickness of each section of the shuttle tube during the quenching process, and therefore it is impossible to adjust the moving distance of the ultra-thin wall shuttle tube in real time by measuring the wall thickness of each section of the shuttle tube during the quenching process. The present invention arranges a laser infrared thermometer on the side of the induction heating coil to control the moving distance of the ultra-thin wall shuttle tube by real-time monitoring the temperature of the shuttle tube during the quenching process. Only when the heating temperature of the shuttle tube reaches the set temperature will it drive the shuttle tube to continue to move downward and extend into the water tank for cooling, thereby ensuring that the heating temperature of each section of the shuttle tube is uniform. At the same time, a cold water heater is connected to the water tank. The water machine controls the water temperature of the water tank in real time through the water chiller to ensure the consistency of the water temperature of the water tank during the entire quenching process of the shuttle tube, thereby further ensuring the quenching effect; the hardness of the shuttle tube after quenching can reach HRC45, and the quenching uniformity can be guaranteed to be above 90%; (3) The shuttle tube is used to make the javelin gun body. Before quenching, the shuttle tube clamp clamps the tail tube according to the length to be cut. When the shuttle tube is quenched, a clear dividing line will be formed between the quenched tube section of the shuttle tube and the unquenched tube section clamped by the shuttle tube clamp. Therefore, after the shuttle tube is quenched, it is only necessary to cut the unquenched tube section clamped by the shuttle tube clamp along the dividing line to obtain a shuttle tube product consistent with the standard length of the javelin gun body. The obtained shuttle tube product does not need to be cut or trimmed, and can be directly welded to the rear gun head.
[0043] The above description is only a preferred embodiment of the present invention and does not constitute any other limitation on the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
