[0003] A quenching furnace typically consists of a heating chamber, a feeding and discharging mechanism, a temperature control system, a cooling system, and a furnace shell. The heating chamber contains heating elements or a combustion device to provide a high-temperature environment.

[0018] The following combination Figures 1-4 This application will be described in further detail below.
[0019] Example: A quenching furnace, referring to Figure 1 and Figure 3 The system includes a bottom shell 1, which is the basic component of the entire device and supports the entire device. Two support blocks 2 are fixedly connected to the top of the bottom shell 1. The support blocks 2 protect the furnace at the top and make it stable. A hot furnace 9 is fixedly connected to the top of the two support blocks 2. The hot furnace 9 is a component used to quench the pathology blades 7. A quenching mechanism 3 is fixedly connected to the bottom of the hot furnace 9. The quenching mechanism 3 quenches the pathology blades 7 in the hot furnace 9. A sealing mechanism 4 is slidably connected to the top of the hot furnace 9. The sealing mechanism 4 prevents the heat inside the hot furnace 9 from dissipating, thereby preventing uneven stress on the pathology blades 7. The quenching mechanism 3 includes two servo motors 31, both of which are fixedly connected to the bottom of the furnace 9. The servo motors 31 are the drive source for the quenching mechanism 3, thus driving other components to rotate. A rotating rod 32 is fixedly connected to the drive end of each servo motor 31, and a quenching rod 33 is fixedly connected to the top of the rotating rod 32. The rotating rod 32 rotates under the power of the servo motors 31, and the quenching rod 33 rotates under the action of the rotating rod 32. The quenching rod 33 itself contains a heating element. The surface is thermally conductive. Multiple flame nozzles 34 are fixedly connected to the outside of the quenching rod 33. The flame nozzles 34 transfer the heat and flame of the quenching rod 33 to the furnace 9. Multiple heat storage rings 35 are fixedly connected to the inside of the quenching rod 33. The heat storage rings 35 store the heat inside the quenching rod 33. Multiple protective rings 36 are fixedly connected to the inner wall of the furnace 9. The protective rings 36 protect the surface of the furnace 9 and also continuously draw the heat inside the furnace 9 towards the center. A limit component 6 is rotatably connected inside one of the protective rings 36. Specifically, the furnace 9 is fixed by the bottom shell 1 and the support block 2. The quenching mechanism quenches the pathological blades 7 inside the furnace 9. The sealing mechanism 4 seals and protects the insertion port to prevent heat loss from the furnace 9, thus ensuring structural stability. The servo motor 31 rotates the rotating rod 32, causing the top quenching rod 33 to rotate. The quenching rod 33 contains a heating element and is thermally conductive. The flame nozzle 34 allows the heat generated by the quenching rod 33 to dissipate. The heat storage ring 35 stores the heat inside the quenching rod 33, preventing it from dissipating. The protective ring 36 transfers heat from inside the furnace 9 to the center, preventing heat loss from contacting the surface of the furnace 9.
[0020] Reference Figure 2 and Figure 4 The sealing mechanism 4 includes a connecting plate 41, which is externally slidably connected to the top of the furnace 9. The connecting plate 41 connects the subsequent sealing components and the base components to stabilize them. A limiting plate 42 is fixedly connected to the bottom of the connecting plate 41. The limiting plate 42 keeps the connecting plate 41 to this position, thereby fixing the pathological blade 7 at the bottom. Multiple rebound columns 43 are fixedly connected to the inner wall of the top of the furnace 9. The rebound columns 43 are squeezed under the action of external force and have their own elasticity. A force-bearing plate 44 is fixedly connected to one side of each of the three rebound columns 43. The force-bearing plate 44 receives the external force and applies force to the rebound column 43. A static sealing ring 45 is fixedly connected to the rear side of the force-bearing plate 44. A clamping plate 47 is slidably connected to the top of the furnace 9. A connecting plate 48 is fixedly connected to the top of the clamping plate 47. A dynamic sealing ring 46 is fixedly connected to the outside of the connecting plate 48. The static sealing ring 45 receives the force applied by the dynamic sealing ring 46 and moves to make the force-bearing plate 44 bear force. The clamping plate 47 clamps and fixes the bottom pathological blade 7 to make it stable. The connecting plate 48 connects the clamping plate 47 and the dynamic sealing ring 46 to make it stable. Specifically, the connecting plate 41 connects the base component and the sealing component, making it convenient for the operator to pick up the pathology blade 7. The limiting plate 42 limits the connecting plate 41, fixing the pathology blade 7 at the bottom. Under the action of the clamping plate 47, the dynamic sealing ring 46 contacts the static sealing ring 45, thereby causing the force plate 44 to bear force, causing the spring column to bear force, and thus applying force to the static sealing ring 45.
[0021] Reference Figures 1 to 3The limiting assembly 6 includes a second rotating rod 61, which is rotatably connected to the inside of the protective ring 36. The second rotating rod 61 receives external force to rotate. A rotating plate 62 is fixedly connected to the front of the second rotating rod 61. The rotating plate 62 receives the force applied by the operator to rotate, causing the second rotating rod 61 to rotate. A limiting block 63 is fixedly connected to the rear of the rotating plate 62. The limiting block 63 receives the rotational force of the second rotating rod 61 to rotate, thereby limiting the rotation of the second rotating rod 61. A connecting plate 64 is rotatably connected to the outside of the limiting block 63. The connecting plate 64 is connected to the top component. The limiting rod is fixedly connected to the front of the hot furnace 9. 65. The limiting rod 65 limits the rotating plate 62, preventing it from rotating downwards. The external rotating rod 32 is rotatably connected to the bottom of the furnace 9. The rotating rod 32 rotates under the action of the servo motor 31. The top of the sealing mechanism 4 is fixedly connected to the picking block 5, which is convenient for operators to pick up and has heat insulation properties. The inside of the static sealing ring 45 is in contact with the outside of the dynamic sealing ring 46. The static sealing ring 45 and the dynamic sealing ring 46 are in contact to seal. The outside of the static sealing ring 45 is slidably connected to the top inner wall of the furnace 9. The static sealing ring 45 rotates under the action of the dynamic sealing ring 46 and comes into contact with the outside of the dynamic sealing ring 46. The bottom of the rotating plate 62 contacts the outside of the limiting rod 65. The rotating plate 62 stops rotating under the action of the limiting rod 65, thereby preventing the limiting block 63 from rotating. The outside of the rotating rod 61 contacts the inside of the connecting plate 64. The rotating rod 61 passes through the inside of the connecting plate 64, thereby stabilizing it. The bottom of the clamping plate 47 is fixedly connected to a pathological blade 7, which is used to quench the blade in the hot furnace 9. The bottom of the clamping plate 47 is fixedly connected to an isolation sheet 8, which is used to isolate the pathological blade 7 and make each blade 7 bear force evenly. The outside of the limiting plate 42 is fixedly connected to the top inner wall of the hot furnace 9. The limiting plate 42 is fixed to the top of the hot furnace 9, thereby facilitating its fixation. The outside of the connecting plate 48 is slidably connected to the top inner wall of the hot furnace 9. The connecting plate 48 receives external force and moves accordingly. Specifically, rotating rod 61 rotates under the action of rotating plate 62, causing limiting block 63 to fix pathology blade 7. Under the action of limiting rod 65, the rotation of rotating plate 62 is restricted. Rotating rod 32 rotates quenching rod 33 under the action of servo motor 31. Picking block 5 facilitates the operator to pick up the pathology blade 7 at the bottom. Under the action of isolation sheet 8, the pathology blade 7 is heated evenly. Static sealing ring 45 moves under the action of dynamic sealing ring 46, so that static sealing ring 45 contacts dynamic sealing ring 46, thereby stabilizing the seal and preventing heat loss. Connecting plate 48 slides on top of furnace 9 under the action of picking block 5.
[0022] The implementation principle of this application embodiment is as follows: First, the operator inserts the pathological blade 7 into the hot furnace 9, and then inserts the rotating rod 2 61 into the connecting plate 3 64. The operator rotates the rotating rod 2 61 to rotate the limiting block 63, thereby fixing the pathological blade 7. At this time, the operator starts the servo motor 31, which drives the rotating rod 1 32 to rotate, thereby rotating the top quenching rod 33. This allows the flame nozzle 34 on the quenching rod 33 to quench the pathological blade 7. Under the action of the heat storage ring 35, the quenching rod 33 continuously generates heat, and under the action of the protective ring 36, the heat continuously moves towards the center.
[0023] Then, when the operator inserts the pathology blade 7 into the hot furnace 9, the connecting plate 41 contacts its limiting plate 42, thereby limiting the connecting plate 41. This causes the dynamic sealing ring 46 around the bottom clamping plate 47 to exert force on the static sealing ring 45 inside the hot furnace 9, which in turn causes the static sealing ring 45 to exert force on the force plate 44, thereby causing the spring column 43 to be squeezed. Under the rebound action of the spring column 43 itself, the static sealing ring 45 exerts force on the dynamic sealing ring 46, thereby stabilizing the seal and achieving a seal at the inlet. In addition, it can stabilize the quenching environment inside the furnace, thereby ensuring that the quenching quality of the pathology blade 7 is uniform and consistent.
