Description

Technical Field

[0001] This invention belongs to the field of bearing forging processing technology, and specifically relates to a forging cooling system. Background Technology

[0002] Bearing forgings require cooling after forging. To meet the requirements for the carbide network structure of the material, the cooling rate of the forgings must be uniform throughout. A cooling rate that is too fast can cause cracks in the parts, while a cooling rate that is too slow will result in the carbide network structure not meeting quality requirements. Currently, cooling fans are used to cool the forgings after forging, but this method is susceptible to fluctuations in ambient temperature, leading to inconsistent product quality. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the purpose of this invention is to provide a forging cooling system that ensures uniform cooling rate of forgings and improves product quality.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a forging cooling system, including a lifting mechanism, a cooling water tank, a feeding mechanism, and a conveying mechanism. The lifting mechanism is fixed above the cooling water tank. The forging moves up and down through the lifting mechanism to be immersed in the cooling water tank or lifted out of the cooling water tank. A feeding mechanism is provided on one side above the cooling water tank. The feeding mechanism pushes the forging lifted out of the cooling water tank to the conveying mechanism.

[0005] Furthermore, the lifting mechanism includes a frame, a lifting cylinder, a transmission assembly, and a tray; the frame is installed above the cooling water tank, the lifting cylinder is fixed to the frame in the vertical direction, the extension and retraction end of the lifting cylinder is connected to the tray through the transmission assembly, and drives the tray to slide on the frame, and the forging is placed on the tray.

[0006] Furthermore, a guide rail is provided on the frame along the vertical direction, and a slider is slidably connected to the guide rail. The movable frame is fixedly connected to the slider and slides with the slider. The tray is fixed to the bottom of the movable frame.

[0008] Furthermore, the unloading mechanism is an unloading cylinder, which pushes the forging out of the lifting mechanism and sends it to the inlet of the conveying mechanism in the horizontal direction.

[0009] Furthermore, the conveying mechanism is a conveyor belt, and an inclined ramp is provided at the entrance of the conveying mechanism. After the forging is pushed out of the lifting mechanism by the unloading mechanism, it slides into the conveying mechanism by its own weight via the inclined ramp.

[0010] Furthermore, the bottom end of the inclined slope is hinged to the conveying mechanism, and a slope cylinder for adjusting the inclination angle of the inclined slope is provided below the inclined slope.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] See appendix Figure 1-10 The forging cooling system includes a lifting mechanism, a cooling water tank 1, a feeding mechanism, and a conveying mechanism. The lifting mechanism is fixed above the cooling water tank 1. The forging 2 is lifted and lowered by the lifting mechanism to be immersed in the cooling water tank or lifted out of the cooling water tank. A feeding mechanism is provided on one side above the cooling water tank. The feeding mechanism pushes the forging lifted out of the cooling water tank to the conveying mechanism.

[0029] Furthermore, the lifting mechanism includes a frame 3, a lifting cylinder 4, a transmission assembly, and a tray 5; the frame 3 is installed above the cooling water tank 1, the lifting cylinder 4 is fixed to the frame 3 in the vertical direction, the extension end of the lifting cylinder 4 is connected to the tray 5 through the transmission assembly, and drives the tray 5 to slide on the frame 3, and the forging 2 is placed on the tray 5.

[0030] Based on the above technical solution, the tray 5 is a fence type to avoid affecting the cooling effect at the bottom of the forging.

[0031] Furthermore, a guide rail 6 is provided on the frame 3 along the vertical direction, and a slider 7 is slidably connected on the guide rail 6. The movable frame 8 is fixedly connected to the slider 7 and slides with the slider 7. The tray 5 is fixed to the bottom of the movable frame 8.

[0032] Furthermore, the transmission assembly includes a gear 9, a fixed rack 10, and a movable rack 11; the fixed rack 10 is fixedly mounted on the frame 3, the movable rack 11 is fixedly mounted on the movable frame 8, the telescopic end of the lifting cylinder 4 is connected to the gear 9, and the fixed rack 10 and the movable rack 11 are located on both sides of the gear 9 and mesh with the gear 9.

[0033] Based on the above technical solution, the lifting cylinder 4 extends, the gear 9 rolls downward along the fixed rack 10, and the movable rack 11 moves downward relative to the gear 9, causing the movable frame 8 and the slider 7 to slide downward along the guide rail 6. The tray 5 and the forging 2 on it are immersed in the cooling water tank 1 for cooling. After cooling, the lifting cylinder 4 retracts, the gear 9 rolls upward along the fixed rack 10, and the movable rack 11 moves upward relative to the gear 9, causing the movable frame 8 and the slider 7 to slide upward along the guide rail 6. The tray 5 and the forging 2 on it are lifted out of the cooling water tank 1, completing the cooling process.

[0034] Furthermore, the unloading mechanism is an unloading cylinder 12, which pushes the forging out of the lifting mechanism and delivers it to the inlet of the conveying mechanism in a horizontal direction. After cooling, the forging 2 is pushed into the conveying mechanism by the unloading cylinder 12.

[0035] Furthermore, the conveying mechanism is a conveyor belt 13, and an inclined ramp 14 is provided at the entrance of the conveying mechanism. After the forging 2 is pushed out of the lifting mechanism by the unloading mechanism, it slides into the conveying mechanism by its own weight via the inclined ramp 14.

[0036] Furthermore, the bottom end of the inclined slope 14 is hinged to the conveying mechanism, and a slope cylinder 15 for adjusting the inclination angle of the inclined slope is provided below the inclined slope. The telescopic end of the slope cylinder 15 is hinged to the lower surface of the inclined slope 14.

[0037] Based on the above technical solution, if the forging 2 cannot fall smoothly into the conveyor belt 13 when it slides down the inclined slope 14, the inclined slope 14 can be made steeper by the slope cylinder 15, forcing the forging 2 to slide down. The fixed end of the slope cylinder 15 is hinged to the conveying mechanism, and the telescopic end of the slope cylinder 15 is hinged to the inclined slope 14, which facilitates angle adjustment.

[0038] Furthermore, several cooling fans 16 for air cooling of forgings are provided above the conveying mechanism. The cooling fans 16 can dry the cooling water on the surface of the forgings 2.

[0039] Furthermore, limiting baffles 17 are provided on both sides of the conveying mechanism to restrict the position of the forging.

[0040] Based on the above technical solution, the limiting baffle 17 can prevent the forging 2 from overstepping its position. The forging cooled by this invention is a bearing ring, and the limiting baffle 17 can ensure the bearing ring remains in an upright position during the conveyor belt 13 conveying process. The inclined ramp 14 and the slope cylinder 15 can also ensure that the bearing ring enters the limiting baffle 17 of the conveyor belt in an upright position.

[0041] Furthermore, a laser sensor 18 is installed above the cooling water tank 1 to detect whether the forging is in place. After the laser sensor 18 detects that the forging 2 has been placed in the tray 5, it activates the lifting cylinder 4 to immerse the forging 2 into the cooling water tank 1 for cooling.

[0042] Furthermore, the cooling water tank 1 is set to a constant temperature, and the cooling water tank 1 is equipped with an infrared thermometer 19.

[0043] Furthermore, the forging cooling system feeds the pallet 5 via the feeding cylinder 20.

[0044] Furthermore, an exit laser sensor 21 and a temperature sensor 22 for detection are provided at the exit of the conveying mechanism.

[0045] The forging cooling process of this invention is as follows:

[0046] 1. The operator delivers the forging completed by the ring rolling process to the pallet. Using an induction switch (laser sensor), the cylinder rod of the lifting cylinder extends and sends the forging into the cooling water tank for cooling.

[0047] 2. Based on the time determined by process verification, the cooling time is preset. After the time is reached, the lifting cylinder retracts and lifts the forging out of the water tank.

[0048] 3. After the induction switch (laser sensor) detects the workpiece, the feeding cylinder and the slope cylinder feed the forging onto the conveyor belt;

[0049] 4. The forgings are transported to the buffer area via a conveyor belt.

[0050] The beneficial effects of this invention are as follows:

[0051] 1. Immersion cooling with a cooling water tank is used to ensure a small temperature difference between the inside and outside of the parts and to ensure the consistency of the cooling temperature of the parts.

[0052] 2. The cooling water tank is equipped with a constant temperature device to ensure the controllability of the cooling temperature;

[0053] 3. The use of a cylinder to drive gears and racks ensures the controllability of the time for parts to enter and exit the water; at the same time, a portion of the force is applied to the support, avoiding the cylinder rod of the lifting cylinder from directly acting on the pallet for lifting operations, thus ensuring the stability of the lifting device.
