Description

Technical Field

[0001] The utility model relates to the technical field of bearing heat treatment processing, in particular to a heat treatment device for bearing processing. Background Art

[0002] Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm, and cooled in solid state to obtain the desired structure and properties. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but rather imparts or improves the performance of the workpiece by changing the internal microstructure of the workpiece or the chemical composition of the workpiece surface.

[0003] Currently, when heat treating bearings, they are first heated in a heating furnace and then kept warm. However, after heating and keeping warm, the bearings cannot be cooled quickly. The bearings need to be manually transported to a cooling area for cooling. The transport and transfer cannot be completed automatically, which is laborious and prone to burns during the transfer process, posing a safety hazard. Utility Model Content

[0007] The upper heating box is mounted above the conveyor belt and has an inlet and an outlet on both sides;

[0008] The lower heating box is installed below the conveyor belt;

[0009] Several flamethrowers are respectively arranged in the upper heating box and the lower heating box and are evenly distributed;

[0010] The placement box is placed on the conveyor belt and a plurality of through holes are opened at the bottom of the placement box;

[0011] The heat preservation cooling box is set on the ground at one side of the conveyor belt end;

[0014] The air cooling component is arranged on the side wall of the thermal insulation cooling box and is communicated with the interior of the thermal insulation cooling box.

[0015] Furthermore, the receiving and conveying component includes an electric push rod and a supporting plate. The electric push rods are symmetrically arranged inside the thermal insulation cooling box, and the electric push rods are connected to the supporting plate spaced apart from the heater.

[0016] Furthermore, the blocking assembly includes a fixing frame, a cylinder and a heat preservation plate. The heat preservation cooling box is provided with a fixing frame, the fixing frame is provided with a cylinder, and the cylinder is connected to the heat preservation plate.

[0017] The above solution realizes the automatic transfer of the bearing placement box from the conveyor belt to the support plate after heating is completed through the receiving conveying component, and then effectively seals the insulation cooling box through the sealing component to start the subsequent insulation process.

[0018] Furthermore, the air cooling component includes a delivery pipe and an air cooler. The delivery pipe and the air cooler connected to the delivery pipe are arranged on the side wall of the thermal insulation cooling box. Several air holes connected to the interior of the thermal insulation cooling box are arranged on the delivery pipe along the height direction.

[0022] Furthermore, heat-resistant plates are provided on the inner walls of the upper heating box and the lower heating box.

[0023] The above solution can reduce the rate of heat loss from the upper heating box / lower heating box to the outside during the flame heating process through the heat-resistant plate, thereby reducing energy consumption.

[0024] Furthermore, a six-freedom robotic arm is respectively provided at the initial end of the conveyor belt and one side of the heat-insulating cooling box, and the six-freedom robotic arm is connected to a hydraulic clamp.

[0025] The above solution can reduce the labor intensity of manual loading and unloading by using a six-freedom robotic arm in conjunction with a hydraulic clamp, while further reducing the safety hazard of burns.

[0026] Furthermore, the inner edge of the insulation board is provided with silicone rubber.

[0027] Furthermore, the side walls and partitions of the placement box are provided with circulation holes.

[0028] The above solution can ensure effective contact between the cold air and the bearing surface during the cooling process through the circulation holes.

[0043] The blocking assembly is arranged above the heat preservation cooling box 3;

[0044] The air cooling component is arranged on the side wall of the thermal insulation cooling box 3 and is communicated with the interior of the thermal insulation cooling box 3 .

[0045] Further refinement of the embodiment of the present invention is as follows: Figure 1 As shown, the receiving and conveying assembly includes an electric push rod 31 and a supporting plate 32 . The electric push rod 31 is symmetrically arranged inside the heat preservation and cooling box 3 . The electric push rod 31 is connected to the supporting plate 32 spaced apart from the heater 301 .

[0046] Further refinement of the embodiment of the present invention is as follows: Figure 1 As shown, the sealing assembly includes a fixing frame 33, a cylinder 34 and an insulation plate 35. The insulation cooling box 3 is provided with a fixing frame 33, the fixing frame 33 is provided with a cylinder 34, and the cylinder 34 is connected to the insulation plate 35; the above scheme is further optimized, and the inner edge of the insulation plate 35 is provided with silicone rubber.

[0047] Further refinement of the embodiment of the present invention is as follows: Figure 1 As shown, the air cooling component includes a delivery pipe 41 and an air cooler 42. The delivery pipe 41 and the air cooler 42 connected to the delivery pipe 41 are provided on the side wall of the thermal insulation cooling box 3. A plurality of air holes connected to the interior of the thermal insulation cooling box 3 are provided on the delivery pipe 41 along the height direction. The air holes are not shown in the figure.

[0048] Further refinement of the embodiment of the present invention is as follows: Figure 2 As shown, the interior of the placement box 2 is divided into several placement areas by partitions 21 (the partitions 21 are made of high-temperature resistant materials), and both the placement box 2 and the partitions 21 are made of high-temperature resistant materials.

[0049] In a further refinement of the embodiment of the present invention, a six-freedom robotic arm is respectively provided at the initial end of the conveyor belt 1 and one side of the thermal insulation cooling box 3, the six-freedom robotic arm is connected to a hydraulic clamp, and a circulation hole 22 is provided on the side wall of the placement box 2 and the partition 21. This embodiment is not shown in the figure.

[0050] It should be noted that the flamethrower 13, the heater 301, the electric push rod 31, the cylinder 34 and the air cooler 42 are all electrically connected to the controller, which is not shown in the figure.

[0051] The workflow of this utility model:

[0052] First, the six-degree-of-freedom robotic arm steadily places the placement box 2 at the initial end of the steel conveyor belt 1. Then the controller controls the steel conveyor belt 1 to work. Then the placement box 2 enters the upper heating box 11 along the entrance. Then the controller controls the flamethrowers 13 in the upper heating box 11 and the lower heating box 12 to work synchronously (the flamethrowing distance is pre-set). Then, the upper and lower sides of the bearing can be simultaneously heated by flamethrowing to ensure uniform heating of the bearing surface. After heating is completed, the placement box 2 leaves the heating area from the exit.

[0053] In the initial state, the controller controls the electric push rod 31 to work and drive the supporting plate 32 to move to the end side of the conveyor belt 1 and slightly below its surface. Then, when the placement box 2 moves to the end area of the conveyor belt 1, it can be automatically transferred to the supporting plate 32. After the transfer is completed, the controller controls the electric push rod 31 to work and drive the supporting plate 32 to move down so that the placement box 2 completely enters the insulation cooling box 3. Then the controller controls the cylinder 34 to work and make the insulation plate 35 seal the upper surface of the insulation cooling box 3 (silicone rubber can improve the sealing effect and is resistant to high temperature). Then the bearing insulation process can be started. During the insulation process, the ambient temperature in the insulation cooling box 3 can be monitored by the heater 301. If the insulation temperature requirement is not met, the temperature is increased to ensure a good insulation effect of the bearing.

[0054] After the bearing insulation process is completed, the controller controls the cylinder 34 to work again and drive the insulation plate 35 away from the top of the insulation cooling box 3. Then, on the basis of natural cooling, the air cooling component is combined to realize the cooling process of the bearing and effectively shorten the cooling time. Finally, after the bearing is cooled, the controller controls the electric push rod 31 to move the placement box 2 to the outside of the insulation cooling box 3. Then, the six-degree-of-freedom mechanical arm on one side cooperates with the hydraulic clamp to realize the clamping and transfer of the placement box 2. Then, the above process is repeated to start a new round of bearing heat treatment operation.

[0055] Compared with the existing technology, this device can complete the heating, insulation and cooling processes of the bearings in an integrated manner. No human intervention is required to transfer the bearings to the cooling area after insulation, thereby effectively reducing labor intensity and safety risks, and achieving better batch heat treatment effects for bearings.

[0056] In some embodiments, heat-resistant plates are provided on the inner walls of the upper heating box 11 and the lower heating box 12, which are not shown in the figure. This embodiment can reduce the rate of heat loss from the upper heating box 11 / lower heating box 12 to the outside during the flame heating process through the heat-resistant plates, thereby reducing energy consumption.
