Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically to an automotive gear processing and forging equipment. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. Forging is generally carried out at high temperatures. Since gear forgings have thermal conductivity, the gears themselves are in a high-temperature state. After a forging is completed, the gears need to be cooled.

[0003] Utility model patent CN217964617U discloses a gear forging cooling device, including a processing box. Multiple vertical rods are fixed to the upper end of the processing box, and a horizontal plate is fixed to the upper end of each vertical rod. An electric push rod is fixed to the bottom of the horizontal plate, and a moving plate is fixed to the head of the electric push rod. Multiple connecting columns are fixed to the bottom of the moving plate, and a support plate is fixed to the bottom of each connecting column. The moving plate is slidably and sealingly connected to the inner wall of the processing box. A flow device is installed inside the processing box. In this device, the flow of cool air between the air injection pipe and the storage box allows for rapid absorption of the temperature on the surface of the forged gear, achieving initial cooling. The coolant at the bottom of the processing box then provides rapid cooling, enabling multi-step cooling of the gear. This avoids damage to the gear caused by direct water spray on the hot gear and results in better cooling performance.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: Although the device can initially cool the gears by introducing external cold air, the gears are stationary after being placed on the top of the support plate, which results in poor airflow to the gears. At the same time, the coolant inside the treatment box will absorb heat and rise in temperature after long-term use, resulting in poor cooling effect on the gears. Utility Model Content

[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figure 1-5 An automotive gear processing and forging equipment includes a movable mechanism 1, a cooling mechanism 2 on one side of the movable mechanism 1, and a drive mechanism 3 on the top of the movable mechanism 1.

[0024] The active mechanism 1 includes a base 101, a processing box 102 fixed to the top of the base 101, a connecting plate 103 fixed to the top of the processing box 102, a top frame 104 fixed to the top of the connecting plate 103, a cylinder 105 fixed to the top of the top frame 104, one end of the cylinder 105 passing through the top frame 104 and fixed to a mounting frame 106, a movable shaft 107 rotatably connected to the lower surface of the mounting frame 106, a placement plate 108 fixed to the top of the movable shaft 107, the processing box 102 is filled with coolant, and a controller 4 is fixed to the surface of the processing box 102.

[0025] Through the above technical solution, the base 101 provides stable support for the entire equipment, the processing box 102 is fixed on it and contains coolant for the final cooling stage, the piston rod of the cylinder 105 extends downward through the top frame 104 and is rigidly connected to the top of the mounting frame 106. When the cylinder 105 receives the command from the controller 4 to start, its piston rod performs telescopic movement, thereby driving the entire mounting frame 106 and the movable shaft 107 and the placement plate 108 below it to move up and down in the vertical direction inside the processing box 102. The movable shaft 107 is rotatably connected to the bottom of the mounting frame 106, and the placement plate 108 is fixed to the top of the movable shaft 107 to support the gears after high-temperature forging. When the cylinder 105 drives the mounting frame 106 downward, the placement plate 108 and the gears on it are immersed in the coolant of the processing box 102; when it moves upward, it lifts the gears out of the liquid surface.

[0026] The cooling mechanism 2 includes a chiller 201. A mounting bracket 202 is provided on one side of the chiller 201. A delivery pump 203 is connected to the cooling water output end of the chiller 201. A first serpentine tube 204 is connected to the delivery end of the delivery pump 203. A fan 205 is fixed on the surface of the first serpentine tube 204. The fan 205 is located on one side of the top of the connecting plate 103. A second serpentine tube 207 is fixed to the bottom of the inner wall of the treatment box 102. A delivery pipe 208 is connected to the output end of the first serpentine tube 204. The delivery pipe 208 passes through the treatment box 102 and is connected to the input end of the second serpentine tube 207. The output end of the second serpentine tube 207 passes through the treatment box 102 and is connected to a return pipe 209. The return pipe 209 is connected to the cooling water input end of the chiller 201.

[0027] Through the above technical solution, the chiller 201 continuously generates low-temperature cooling water; the delivery pump 203 pressurizes and pumps the low-temperature cooling water output from the chiller 201 into the first serpentine pipe 204. The first serpentine pipe 204 is coiled and arranged. After the fan 205 fixed on its surface is started, the forced airflow blows through the first serpentine pipe 204, so that the cooling water flowing through the pipe can perform efficient heat exchange with the air, significantly reducing the air temperature and generating a strong cold air. This cold air blows directly onto the gears that were in a suspended state before immersion above the treatment box 102, performing forced air cooling preheating. Cooling: The subsequent cooling water is pumped through the delivery pipe 208 to the second serpentine pipe 207, which is submerged at the bottom of the coolant in the treatment tank 102. The low-temperature cooling water flowing in the second serpentine pipe 207 continuously exchanges heat with the coolant surrounding it in the treatment tank 102, absorbing heat from the coolant and effectively suppressing the overall temperature rise of the coolant caused by long-term operation. Finally, the cooling water that has absorbed heat and heated up in the second serpentine pipe 207 returns to the chiller 201 through the return pipe 209 for further cooling, forming a closed-loop cooling system.

[0028] Multiple heat-conducting fins 206 are fixed on the surface of the first serpentine tube 204, and the heat-conducting fins 206 are fixedly connected to the surface of the fan 205 and the mounting bracket 202.

[0029] Through the above technical solution, the heat-conducting fins 206 are made of metal material with high thermal conductivity. Their base is firmly welded or tightly attached to the outer surface of the first serpentine tube 204 and extends into multiple thin sheet-like structures. The introduction of the heat-conducting fins 206 enhances the air cooling efficiency of the first serpentine tube 204.

[0030] The drive mechanism 3 includes a geared motor 301, which is fixed to the top of the mounting frame 106. The output shaft of the geared motor 301 passes through the mounting frame 106 and is fixed with a drive shaft 302. Both the drive shaft 302 and the surface of the movable shaft 107 are fixed with sprockets 303. The two sprockets 303 are connected by chain drive. Both the sprockets 303 and the chain they use are made of stainless steel.

[0031] Through the above technical solution, when the geared motor 301 receives the command from the controller 4 to start, its output shaft drives the drive shaft 302 to rotate, and the sprocket 303 on the drive shaft 302 rotates accordingly. Through the meshing transmission of the chain, the power and rotational motion are transmitted to the sprocket 303 on the movable shaft 107, thereby driving the movable shaft 107 to rotate around its axis. The geared motor 301 provides the required torque and reduces the speed to a rotational speed suitable for the gear cooling process. The stainless steel sprocket 303 and chain have excellent corrosion resistance and wear resistance and can adapt to the moisture in the cooling environment.

[0032] A stirring blade 111 is fixed below the surface of the movable shaft 107.

[0033] With the above technical solution, when the drive mechanism 3 drives the movable shaft 107 to rotate through chain transmission, the stirring blade 111 rotates synchronously. The rotating blade generates strong shearing and pushing action on the surrounding coolant, forming complex turbulence and forced circulation flow inside the coolant. This flow breaks the temperature stratification formed by insufficient natural convection of the coolant and promotes the uniformity of coolant temperature in various parts of the tank.

[0034] A circular slide rail 109 is fixed to the surface of the mounting frame 106, and a slider 110 is slidably connected to the surface of the circular slide rail 109. The top of the slider 110 is fixedly connected to the bottom of the placement plate 108.

[0035] Through the above technical solution, the combined use of the circular slide rail 109 and the slider 110 provides high-precision, high-rigidity and high-stability support for the rotation of the placement plate 108, preventing the movable shaft 107 from being subjected to excessive bending moment and causing bending deformation or vibration, thus ensuring the concentricity and smoothness of the rotation.

[0036] A guide rod 112 slides through the surface of the top frame 104, and the bottom of the guide rod 112 is fixedly connected to the top of the mounting frame 106.

[0037] With the above technical solution, when the cylinder 105 pushes the mounting frame 106 to move, the guide rod 112 will slide on the surface of the top frame 104, thereby ensuring that the mounting frame 106 moves up and down in a straight line.

[0038] Working principle: After the high-temperature forged gear is placed on the high-position placement plate 108, the controller 4 starts the cooling mechanism 2: the chiller 201 cools the gear, and the delivery pump 203 pumps low-temperature cooling water into the first serpentine pipe 204. At the same time, the fan 205 starts to generate strong cold air to pre-cool the gear. Then, the controller 4 starts the drive mechanism 3: the geared motor 301 drives the movable shaft 107, the fixed placement plate 108, and the stirring blade 111 to rotate through the chain drive of the sprocket 303, so that the gear is heated evenly in the air cooling. Then, the controller 4 commands the piston rod of the cylinder 105 to extend and push the safety valve. The frame 106 descends smoothly along the vertical path guided by the guide rod 112, causing the rotating gear to gradually immerse itself in the coolant in the treatment tank 102. The rotation of the gear ensures that its surface is in full and uniform contact with the coolant. At the same time, the rotating stirring blade 111 powerfully stirs the coolant to eliminate temperature stratification and enhance heat transfer. After liquid cooling is completed, the cylinder 105 lifts the gear out of the liquid surface. Rotation and cold air can assist in draining and final cooling. Finally, the device is reset and the part is removed. This device solves the problems of uneven cooling, liquid temperature rise, and sudden cooling damage by combining pre-cooling air cooling, rotation enhancement, liquid cooling with active coolant temperature control and stirring.
