Detailed Implementation

[0025] refer to Figure 1 The implementation process of intelligent heat treatment of workpieces is described in detail:

[0026] A smart heat treatment method, comprising the following steps:

[0027] Step 1: Clamp and suspend the workpiece to fix it in place and facilitate quenching.

[0028] Step 2: The workpiece is lowered into the coolant for quenching, achieving rapid cooling of the workpiece to the temperature of the coolant.

[0029] Step 3: Circulate coolant. Ensure the coolant is circulated and used, and control the coolant temperature to ensure the quenching effect of the workpiece.

[0030] Step 4: Lift the quenched workpiece up and disassemble it for storage.

[0031] In conjunction with the above embodiments, the following functions can also be achieved;

[0032] refer to Figure 2 , 4 Section 7 details the implementation process of the quenching coolant circulation:

[0033] The system includes a quenching rack 11, a quenching frame 12 fixedly connected to the quenching rack 11, and a flow ramp 13 fixedly connected to the quenching frame 12. The space enclosed by the quenching frame 12 is used for quenching the workpiece. When the coolant inside the quenching frame 12 accumulates on the flow ramp 13 at the upper end, the coolant flows out and slides down to prevent the accumulated coolant from flowing back and affecting the quenching effect on the workpiece. Multiple straight pipes 63 are fixedly connected to the lower end of the quenching rack 11, and a return flow rack 62 is fixedly connected to the multiple straight pipes 63. Multiple bent pipes 61 are fixedly connected to the return flow rack 62, and all bent pipes 61 are fixedly connected to the quenching rack 11. Branch pipes are fixedly connected to the return flow rack 62, and the branch pipes communicate with an externally installed cooling device that can provide low-temperature cooling. The coolant is supplied with low-temperature air through the branch pipe to the return rack 62, thereby cooling the circulating coolant and ensuring the quenching effect of the workpiece. The coolant flows through the return rack 62 to multiple straight pipes 63, and then into the quenching rack 11 and into the quenching frame 12 to accumulate coolant, thereby quenching the workpiece. The accumulated coolant flows out from the ramp plate 13 and falls onto the quenching rack 11, and then flows into multiple bends 61 and back into the return rack 62 to achieve coolant circulation. Each of the multiple straight pipes 63 is fixedly connected with a check valve to prevent coolant backflow. Each of the multiple straight pipes 63 is fixedly connected with a pump to drive the coolant to circulate continuously. A thermometer is fixedly connected to the return rack 62 to monitor the temperature of the coolant in the return rack 62 at all times.

[0034] In conjunction with the above embodiments, the following functions can also be achieved;

[0035] refer to Figure 2 , 3 Section 10 details the implementation process for pushing the coolant upward:

[0036] A pusher frame 21 is rotatably connected to the quenching frame 11, and a lifting frame 22 is fixedly connected to the pusher frame 21. The pusher frame 21 is fixedly connected to the output shaft of the reduction motor II, which is also fixedly connected to the quenching frame 11. When the reduction motor II is started, it drives the pusher frame 21 to rotate, thus pushing the flowing coolant to ensure its rapid flow. The pusher frame 21 also drives the lifting frame 22 to rotate. The diameter of the circle scanned by the lifting frame 22 during rotation is equal to the diameter of the inner wall of the quenching frame 12. As the lifting frame 22 rotates, it pushes the coolant at the lower end of the quenching frame 12 upward, thereby promoting continuous circulation of the coolant and ensuring the quenching effect of the workpiece.

[0037] In conjunction with the above embodiments, the following functions can also be achieved;

[0038] refer to Figure 7 , 8 Sections 9 and 10 detail the implementation process for ensuring thorough mixing of the coolant and cold air to guarantee the coolant temperature:

[0039] A mixing rack 71 is rotatably connected to the reflux rack 62, and a gear ring 72 is fixedly connected to the mixing rack 71. Multiple eccentric wheels 73, which drive the gear ring 72 to rotate, are rotatably connected to the reflux rack 62. The multiple eccentric wheels 73 are respectively fixedly connected to the output shafts of multiple geared motors III. The multiple geared motors III are all fixedly connected to the reflux rack 62. When the multiple geared motors III are started, the multiple geared motors III drive the multiple eccentric wheels 73 to rotate. The multiple eccentric wheels 73 synchronously mesh and drive the gear ring 72 to rotate. The rotation of the gear ring 72 drives the mixing rack 71 to rotate, thereby achieving full mixing of the fluid in the reflux rack 62, thereby ensuring the temperature of the coolant, and thus ensuring the quenching effect of the coolant on the workpiece.

[0040] In conjunction with the above embodiments, the following functions can also be achieved;

[0041] refer to Figure 4 The detailed implementation process for ensuring the temperature of the coolant is as follows:

[0042] A heat insulation plate 31 is fixedly connected to the quenching frame 11, and an outer cover 32 is fixedly connected to the quenching frame 11. The heat insulation plate 31 can isolate the coolant accumulated in the quenching frame 12 from the coolant stored in the outer cover 32, preventing heat exchange between the coolant accumulated in the quenching frame 12 and the coolant stored in the outer cover 32, which would affect the quenching effect of the coolant accumulated in the quenching frame 12 on the workpiece. A temperature monitoring device is fixedly connected to the heat insulation plate 31, so that the temperature of the coolant in the quenching frame 12 can be monitored at all times.

[0043] In conjunction with the above embodiments, the following functions can also be achieved;

[0044] refer to Figure 4 and 5 The implementation process of suspending the workpiece is described in detail:

[0045] Multiple guide rods 33 are fixedly connected to the outer cover 32, and a lifting plate 41 is slidably connected to the multiple guide rods 33. A hook 42 is fixedly connected to the lifting plate 41, so that the clamping fixture for clamping the workpiece is suspended on the hook 42 for suspension, thereby driving the lifting plate 41 to rise and fall, and then lowering the workpiece into the coolant for quenching.

[0046] In conjunction with the above embodiments, the following functions can also be achieved;

[0047] refer to Figure 5The following details the implementation process of driving the lifting plate 41 to rise and fall:

[0048] Two geared motors I34 are fixedly connected to the outer cover 32. Each geared motor I34 has a lead screw I35 fixedly connected to its output shaft to drive the lifting plate 41 to rise and fall. When the two geared motors I34 are started, they drive the two lead screws I35 to rotate. The two lead screws I35 mesh with each other to drive the lifting plate 41 to rise and fall, thereby immersing the workpiece in the coolant to achieve quenching.

[0049] In conjunction with the above embodiments, the following functions can also be achieved;

[0050] refer to Figure 6 and 10 The following details the process of sealing and quenching the workpiece:

[0051] Two lead screws II 51 are rotatably connected to the outer cover 32. Multiple transmission frames 53 are connected to the two lead screws II 51. The multiple transmission frames 53 are respectively fixedly connected to the two sealing plates 52. The two lead screws II 51 are respectively fixedly connected to the output shafts of multiple geared motors IV. The multiple geared motors IV are all fixedly connected to the outer cover 32. When the multiple geared motors IV are started, the multiple geared motors IV drive the two lead screws II 51 to rotate. As the two lead screws II 51 rotate, they drive the multiple transmission frames 53 through threads to drive the two sealing plates 52 to slide. When the two sealing plates 52 are in contact, they cover the workpiece, thereby realizing the quenching of the workpiece.

[0052] In conjunction with the above embodiments, the following functions can also be achieved;

[0053] refer to Figure 6 The following details the implementation process of driving the two sealing plates 52 to slide synchronously in opposite directions:

[0054] The two lead screws II 51 have opposite threads at both ends, which ensures that when the two lead screws II 51 rotate, they synchronously drive the transmission frame 53 on them to slide in opposite directions, thereby achieving the sealing of the workpiece by the two sealing plates 52 and ensuring the quenching effect of the coolant on the workpiece.

[0055] In conjunction with the above embodiments, the following functions can also be achieved;

[0056] refer to Figure 9 The process of driving the coolant to cool down is explained in detail:

[0057] Multiple spiral plates are fixedly connected to the mixing rack 71, thereby driving the coolant to flow when the mixing rack 71 rotates, thus achieving rapid cooling of the coolant.
