Description

Technical Field

[0001] The invention belongs to the technical field of automobile bearing processing, and in particular relates to an overheating emergency regulating device for heat treatment of automobile shaft parts. Background Art

[0002] As key load-bearing components, automotive shafts (such as axles, drive shafts, and steering shafts) have mechanical properties that directly impact the safety and durability of the vehicle. Heat treatment processes are a key means of improving the strength, toughness, and fatigue life of shafts. This article reviews the main heat treatment technologies currently used for automotive shafts, including quenching and tempering (quenching and high-temperature tempering), induction hardening, carburizing and quenching, and nitriding, and analyzes the effects of different processes on the material structure and properties. Studies have shown that after quenching and tempering, medium-carbon alloy steels (such as 40Cr and 42CrMo) can obtain a uniform tempered bainite structure, achieving a tensile strength of 800-1000 MPa while maintaining good toughness. Induction hardening, through rapid heating and cooling, forms a high-hardness martensitic layer (HRC 50-55) on the shaft surface, significantly improving wear resistance. However, the depth of the hardened layer must be controlled to avoid brittle fracture. For high-load shafts, carburizing and quenching (such as 20CrMnTi) can form a carbon-rich hardened layer (depth 0.8-1.5mm) on the surface, achieving gradient performance of "hard outside and tough inside".

[0003] A search revealed that, among the prior art, Chinese Patent Publication No. CN222250884U, with authorization announcement dated December 24, 2024, discloses a heat treatment device for automotive bearings. The device, which relates to the field of automotive bearing processing technology, comprises a processing chamber and a mounting slot formed on the top of the processing chamber, in which an arc-shaped quenching ring is fixedly embedded. A feed hopper is fixedly mounted on the top of the processing chamber, and two symmetrically arranged rotating shafts are rotatably mounted on the back side of the processing chamber. Sprockets are fixedly mounted on the shaft walls of the two rotating shafts, and a chain is mounted on the outer sides of the two sprockets. Multiple spaced vertical plates are fixedly mounted on the outer sides of the chains, and multiple crossbars are rotatably mounted on the inner sides of the vertical plates. Support rollers are fixedly mounted on the rod walls of the crossbars, and a motor is fixed on the back side of the processing chamber. The processing chamber, arc-shaped quenching ring, rotating shaft, sprockets, chain, motor, vertical plates, crossbars, support rollers, and guide friction rings provided in this application can perform rotational heat treatment on bearings that have fallen into the feed hopper. Multiple bearings can also be heat treated simultaneously, improving heat treatment efficiency.

[0004] However, the equipment still has the following defects: although it can rotate and heat treat the bearings dropped in the feed hopper in the processing chamber, arc quenching ring, rotating shaft, sprocket, chain, motor, vertical plate, cross bar, support roller and guide friction ring, and can perform synchronous heat treatment on multiple bearings at the same time to improve the heat treatment efficiency, it is unable to transmit the damaged tissue of the bearings in the quenching process to the outside in the event of an emergency, and there are many safety hazards for personnel entering the processing chamber.

[0030] Both ends of the arc-shaped quenching cover 3 are provided with sealing pieces 19, and a heat collecting cavity 20 is provided between the inner wall of the arc-shaped quenching cover 3 and the two sets of sealing pieces 19.

The inner wall of the feeding channel 21 is provided with a plurality of groups of bearings 24 to be processed (exemplary, as shown in FIG. Figure 5 and Figure 6 shown).

[0031] Specifically, the feeding channel 21 places several groups of bearings 24 to be processed inside it, and utilizes the inclined design of the feeding channel 21. When the output end of the electric telescopic rod 23 pushes the sealing plate 22 to rise, a group of bearings 24 to be processed is automatically put into the assembly cavity 42, and is isolated under the action of two groups of isolation plates 43 in each group of assembly cavities 42, so that the bearings 24 to be processed during the heat treatment process can be stored independently, and then the output end of the cylinder 46 is used to push the clamping plate 44 to clamp and position the two ends of the bearings 24 to be processed.

[0032] The linkage assembly 4 includes a linkage shaft 41; illustratively, as Figure 7 and Figure 8 shown.

[0033] The linkage shaft 41 is rotatably connected to the inner wall of the arc-shaped quenching cover 3, and the outer wall of the linkage shaft 41 is provided with an assembly cavity 42, and the assembly cavity 42 is communicated with the inner wall of the arc-shaped quenching cover 3, and the inner wall of the assembly cavity 42 is fixedly connected with a plurality of groups of isolation plates 43, and two groups of clamping plates 44 are slidably connected between the plurality of groups of isolation plates 43. Both ends of the linkage shaft 41 are embedded with a plurality of groups of cylinders 46 with the same number as the cylinder clamping plates 44, and the plurality of groups of cylinders 46 are fixedly connected with the inner wall of the arc-shaped quenching cover 3. The output ends extend into the assembly cavity 42 and are transmission-connected to the clamping plate 44. A reflux cavity 45 is provided at the center of the central axis of the linkage shaft 41. Several groups of through holes 47 are also provided on the linkage shaft 41. One end of several groups of through holes 47 is interconnected with the assembly cavity 42, and the other ends of several groups of through holes 47 are interconnected with the reflux cavity 45. An outer ring gear 48 is fixedly connected to the outer wall of the linkage shaft 41 and one side close to the end, and the outer ring gear 48 is meshed with the driving gear 17.

[0035] The blanking assembly 5 includes a blanking shell 51; for example, Figure 9 shown.

[0036] A water pipe joint 52 is embedded in the top of the unloading shell 51, and the water pipe joint 52 is L-shaped. The inner wall of the unloading shell 51 is fixedly connected with a porous plate 53 in an inclined shape. A heat insulation plate 54 is fixedly connected between one side of the bottom end of the porous plate 53 and the bottom end of the inner wall of the unloading shell 51. A detection hole 55 is provided on one side wall of the unloading shell 51, and the detection hole 55 is located above the porous plate 53. The detection hole 55 is interconnected with a group of temperature sensors 10. A recovery hole 56 is provided at the bottom of the unloading shell 51, and the recovery hole 56 is interconnected with one end of the return pipe 18.

[0037] Specifically, the output end of the servo motor drives the driving gear 17, so that the outer ring gear 48 is engaged with the driving gear 17, and the linkage shaft 41 is driven to rotate, which is used to transfer a group of bearings 24 to be processed into the discharge shell 51, and utilize the injection of normal temperature liquid in the water pipe joint 52 to pour the normal temperature liquid on the surface of the bearings 24 to be processed for the purpose of quenching. Then, the temperature sensor 10 in the detection hole 55 is used to detect the temperature of the bearings in the quenching state. When the bearing is damaged or splashed during the quenching process, the inclined surface design of the porous plate 53 is used to discharge the bearing fragments to one side of the discharge port 6 for emergency treatment of the bearings during the quenching process.

[0038] Specifically, the feeding channel 21 places several groups of bearings 24 to be processed therein, and by utilizing the inclined design of the feeding channel 21, when the output end of the electric telescopic rod 23 pushes the sealing plate 22 upward, a group of bearings 24 to be processed is automatically delivered into the assembly cavity 42. The two groups of isolation plates 43 in each assembly cavity 42 isolate the bearings 24 to be processed during the heat treatment process. The bearings 24 to be processed are then clamped and positioned at both ends by the clamping plates 44 pushed by the output end of the cylinder 46. The outlet pipe 13 uses a circulating pump to input the heat in the quenching furnace 2 into the arc-shaped quenching cover 3, thereby heating the bearings 24 to be processed in each group of assembly cavities 42. In this process, the output end of the cylinder 46 pushes the clamping plate 44 to squeeze the bearings 24 to different strengths, thereby detecting the strength of the bearings 24 to resist deformation under high temperature. The temperature sensor 10 in the feed detection hole 11 in the arc-shaped quenching cover 3 is used to detect the temperature of the bearings 24 to be processed before quenching. The output end of the servo motor drives the driving gear 17, so that the outer ring gear 48 is engaged with the driving gear 17, and the linkage shaft 41 is driven to rotate, which is used to transfer a group of bearings 24 to be processed into the discharge housing 51, and utilize the injection of normal temperature liquid in the water pipe joint 52 to pour the normal temperature liquid on the surface of the bearings 24 to be processed for the purpose of quenching. Then, the temperature sensor 10 in the detection hole 55 is used to detect the temperature of the bearings in the quenching state. If the bearing is damaged or splashed during the quenching process, the inclined surface design of the porous plate 53 is used to discharge the bearing fragments to one side of the discharge port 6, which is used for emergency treatment of the bearings during the quenching process. The continuous rotation of the linkage shaft 41 can transfer the quenched bearing to one side of the heat insulation plate 54, and use the temperature sensor 10 in the discharge detection hole 12 to detect the temperature of the quenched bearing to ensure the bearing temperature after quenching and cooling.

[0039] The working principle of the overheat emergency adjustment device for heat treatment of automobile shaft parts proposed in the embodiment of the present invention is as follows: Several groups of bearings 24 to be processed are placed inside the feeding channel 21. Utilizing the inclined design of the feeding channel 21, a group of bearings 24 to be processed is automatically placed into the assembly chamber 42 while the sealing plate 22 is pushed upward by the output end of the electric telescopic rod 23. The bearings 24 are isolated by two groups of isolation plates 43 in each assembly chamber 42, so that the bearings 24 to be processed during the heat treatment process can be stored independently. The clamping plates 44 are pushed by the output end of the cylinder 46 to clamp and position the two ends of the bearings 24 to be processed. The heat in the quenching furnace 2 is input into the arc-shaped quenching cover 3 by a circulating pump through the air outlet pipe 13, thereby heating the bearings 24 to be processed in each group of assembly cavities 42. In this process, the output end of the cylinder 46 pushes the clamping plate 44 to squeeze the bearings 24 to different degrees of strength, thereby testing the deformation resistance of the bearings 24 to be processed under high temperature conditions. The temperature sensor 10 in the feed detection hole 11 in the arc-shaped quenching cover 3 is used to detect the temperature of the bearings 24 to be processed before quenching. The output end of the servo motor drives the driving gear 17, and in the process of meshing the outer gear ring 48 with the driving gear 17, the linkage shaft 41 is driven to rotate, which is used to transfer a group of bearings 24 to be processed into the discharge housing 51, and utilize the injection of normal temperature liquid in the water pipe joint 52 to pour the normal temperature liquid on the surface of the bearings 24 to be processed for the purpose of quenching. Then, the temperature sensor 10 in the detection hole 55 is used to detect the temperature of the bearings in the quenching state. If the bearing is damaged or splashed during the quenching process, the inclined surface design of the porous plate 53 is used to discharge the bearing fragments to one side of the discharge port 6, which is used for emergency treatment of the bearings during the quenching process. The quenched bearing can be transferred to one side of the heat insulation plate 54 by the continuous rotation of the linkage shaft 41, and the temperature of the quenched bearing can be detected by the temperature sensor 10 in the discharge detection hole 12 to ensure the bearing temperature after quenching and cooling.
