[0002] In the field of modern industrial manufacturing, especially for the processing of high-performance metal materials such as high-carbon chromium bearing steel, annealing is a crucial step. The annealing process aims to change the physical and mechanical properties of the material, such as hardness, strength and toughness, through heating and subsequent cooling, to meet specific application requirements. In the production of high-carbon chromium bearing steel, this material has extremely high requirements for cooling rate and uniformity due to its special chemical composition and microstructure.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art without creative effort on the basis of the embodiments in the present application, fall within the scope of the present application. Figure 2 The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art without creative effort on the basis of the embodiments in the present application, fall within the scope of the present application.

[0018] Please refer to Figures 1-4 The present application provides a technical solution: a cooling atomization device for annealing of high-carbon chromium bearing steel, comprising a support frame, a cooling bin 5 is arranged on the support frame, a vertical side support plate 1 is arranged in the cooling bin 5, and at least five groups of flow guide seats are arranged between the side support plates 1.

[0019] Specifically, the support frame is arranged obliquely.

[0020] One end of the bottom support bracket 3 is long, and one end is short, so the support frame is arranged obliquely. The obliquely arranged support frame helps the bearing steel to be automatically guided out, and also facilitates the recovery of the cooling liquid.

[0021] More specifically, the support frame comprises a bottom support bracket 3, a reinforcing cross brace and a transverse support plate 4. The bottom support bracket 3 has a trapezoidal structure, and a transverse support plate 4 is arranged at the upper end of the bottom support bracket 3. The transverse support plate 4 is fixedly connected between the cooling bin 5 and the bottom support bracket 3. A reinforcing cross brace is arranged in the middle of the bottom support bracket 3.

[0022] The bottom support bracket 3 adopts a trapezoidal structure. This design not only increases the stability of the structure, but also effectively disperses the overall weight of the equipment, ensuring that the device does not shake or tilt during operation.

[0023] The transverse support plate 4 serves as a connecting component between the cooling bin 5 and the support frame, and plays a connecting role. The cooling bin 5 is stably installed on the support frame by fixed connection, ensuring the stability and safety of the cooling bin 5 during operation.

[0024] The reinforcing cross brace further enhances the firmness of the support frame. It prevents structural deformation caused by external forces and effectively maintains the integrity of the overall structure.

[0025] The upper end of the cooling bin 5 is provided with a nozzle holder seat 6, and an atomization nozzle seat 7 is arranged between the nozzle holder seats 6. The nozzle holder seat 6 and the atomization nozzle seat 7 are connected through a rotating main shaft 14. One end of the rotating main shaft 14 is sleeved with a swing arm 11, and the swing arm 11 is engaged with a rack 10 below it.

[0026] The nozzle rack seat 6 is located at the upper end of the cooling bin 5 and is composed of two vertically arranged steel plates. It provides stable support for the atomizing nozzle seat 7 and ensures that it can accurately align the position of the steel material that needs to be cooled.

[0027] A rectangular hole is provided on the cooling bin 5 to accommodate the atomizing nozzle seat 7. When the atomizing nozzle seat 7 rotates, it will not interfere with the rotation of the atomizing nozzle seat 7.

[0028] Specifically, the atomizing nozzle seat 7 is provided with a groove, and a through hole in the middle of the groove is provided with an atomizer.

[0029] The through hole is internally threaded, and the external threads outside the atomizer are connected. The threaded connection can be easily disassembled, facilitating later maintenance and maintenance.

[0030] The atomizer atomizes the cooling liquid into fine particles and uniformly spreads it onto the surface of the high-carbon chromium bearing steel to be processed, achieving efficient cooling and helping to improve cooling efficiency and uniformity, reducing quality problems caused by local overcooling or overheating of the steel.

[0031] The rotating main shaft 14 connects the nozzle rack seat 6 and the atomizing nozzle seat 7. Through its own rotation, it drives the atomizing nozzle seat 7 to adjust the angle within a certain range to adjust the spraying direction according to the actual needs to adapt to the cooling needs of steel materials of different shapes and sizes.

[0032] The swing arm 11 converts the rotary motion of the drive motor 13 into the angular adjustment action of the atomizing nozzle seat 7. The spraying angle can be accurately adjusted by controlling the drive motor 13 to achieve the best cooling effect.

[0033] The rack 10 is slidingly arranged in the rack slide seat 9 groove on the cooling bin 5 and is engaged with the swing arm 11. When the drive motor 13 is working, the rack 10 is moved forward and backward through the strip-shaped connecting plate 8, thereby causing the swing arm 11 to swing and changing the spraying angle of the atomizing nozzle seat 7.

[0034] The rack 10 is slidingly arranged in the rack slide seat 9 groove on the cooling bin 5, one side of the rack 10 is provided with a rotating shaft, the end of the rotating shaft is provided with a bracket sliding groove, the bracket sliding groove is provided with a adapter block, one end of the adapter block is connected with one end of the strip-shaped connecting plate 8, the other end of the strip-shaped connecting plate 8 is connected with the output end of the drive motor 13, and the drive motor 13 is connected with the motor mounting plate 12 arranged on the cooling bin 5.

[0035] The rack 10 is slidingly arranged in the rack slide seat 9 groove, which plays a role in transmitting power.

[0036] The rack slide 9 provides a stable sliding track for the rack 10, preventing the rack 10 from deviating or jamming during movement, ensuring the smoothness and accuracy of the rack 10 movement.

[0037] The shaft end is provided with a bracket sliding groove for accommodating and fixing the adapter block. The bracket sliding groove allows the adapter block to move along the sliding groove, so that the power of the driving motor 13 is smoothly transmitted to the rack 10.

[0038] This structure realizes the reciprocating motion of the rack 10, which in turn drives the atomizing nozzle 7 to swing back and forth, ensuring the uniformity of spraying.

[0039] The adapter block is a component connecting the rack 10 and the strip-shaped connecting plate 8, responsible for converting the linear motion of the strip-shaped connecting plate 8 into the sliding motion of the rack 10.

[0040] Specifically, the middle position of the adapter block is a protrusion, the width of the protrusion is consistent with the width of the sliding groove in the bracket sliding groove, and one side of the protrusion is provided with a baffle, the width of the baffle is wider than the width of the sliding groove.

[0041] The middle protrusion of the adapter block matches the bracket sliding groove, ensuring its smooth movement in the sliding groove, while the baffle prevents the adapter block from coming off the sliding groove, improving the safety of use.

[0042] One end of the strip-shaped connecting plate 8 is connected to the adapter block, and the other end is connected to the output end of the driving motor 13, serving as a power transmission bridge. Through the linear motion of the strip-shaped connecting plate 8, the power of the driving motor 13 is transmitted to the rack 10.

[0043] The driving motor 13 is fixed on the motor mounting plate 12 on the cooling bin 5, ensuring its stability during operation.

[0044] Further, the flow guide seat is composed of a roller shaft and a roller set 2, and the roller shaft is sleeved with the roller set 2.

[0045] The flow guide seat is a component inside the cooling bin 5 for guiding the movement of steel. It ensures that the steel can smoothly pass through the cooling area during cooling, avoiding surface damage or other quality problems caused by friction or collision.

[0046] The roller shaft provides the basis for support and rotation. Multiple roller sets 2 can be installed on it, and the roller sets 2 rotate freely along the shaft, reducing the direct contact and friction between the steel and the flow guide seat.

[0047] The roller set 2 is composed of multiple rollers, with an arc in the middle for placing the steel. The roller set allows the steel to move smoothly and stably inside the cooling bin 5, reducing the resistance of the steel during movement and the wear on the surface of the steel.

[0048] Further, the cooling bin 5 is provided with a slot for avoiding the movement of the adapter block.

[0049] The slot provided on the cooling bin 5 is to avoid the interference that may be caused by the movement of the adapter block, and provides sufficient space for the movement of the adapter block, the strip-shaped connecting plate 8 and the bracket sliding groove at the end of the rotating shaft, so as to avoid the poor operation or damage of the equipment due to mechanical interference.

[0050] In use: the high-carbon chromium bearing steel to be annealed is placed at the entrance end of the cooling bin 5. After the steel enters the cooling bin 5, it will contact the flow guide seat between the side support plates 1. Under the action of gravity, the roller set 2 on the flow guide seat rotates with the forward movement of the steel, guiding the steel to pass through the cooling area smoothly. At the same time, the atomizer starts to work, and the driving motor 13 is started to drive the strip-shaped connecting plate 8 to rotate. At this time, the strip-shaped connecting plate 8 drives the adapter block to move in the bracket sliding groove at the end of the rotating shaft, and then drives the rack 10 to move back and forth along the groove of the rack sliding seat 9, so as to make the swing arm 11 swing and change the spraying angle of the atomizing spray seat 7. The cooling liquid is atomized into small particles and uniformly distributed on the surface of the high-carbon chromium bearing steel to be treated, so as to improve the cooling efficiency.

[0051] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
