Description

TECHNICAL FIELD

[0001] The application relates to the technical field of aluminum alloy profiles, and in particular to a heat treatment equipment for aluminum alloy profile machining and a use method. BACKGROUND

[0002] The aluminum alloy profile is an aluminum product with a specific cross-sectional shape, which is made of aluminum as the main component and a proper amount of alloying elements (such as magnesium, silicon, copper, zinc, etc.) through hot melting and extrusion processes. Due to its light weight, high strength, corrosion resistance, easy processing, good electrical and thermal conductivity, and strong recyclability, the aluminum alloy profile has become an indispensable key material in modern industrial production and construction engineering, and its application range almost covers all important fields of the national economy.

[0003] In the production and processing of aluminum alloy profiles, heat treatment is a crucial process. Through a series of processes such as heating, holding, and cooling, the microstructure of the aluminum alloy can be effectively improved, thereby significantly improving its mechanical properties (such as strength, hardness, toughness, wear resistance, etc.) and use performance (such as corrosion resistance, fatigue resistance, etc.), ensuring that the aluminum alloy profile can meet the stringent use requirements in different application scenarios.

[0004] However, the existing heat treatment equipment for aluminum alloy profile machining still has many technical defects and deficiencies that need to be solved in actual application: Firstly, most of the existing heat treatment equipment can only realize fixed-position heating of the aluminum alloy profile, and cannot effectively rotate and translate the aluminum alloy profile, resulting in inconsistent distances between different parts of the aluminum alloy profile and the heat source, uneven heating, and further performance differences in the aluminum alloy profile after heat treatment, poor product quality stability, and reduced heat treatment efficiency, which is difficult to meet the needs of large-scale industrial production.

[0005] Secondly, the existing equipment lacks effective shaking mechanisms and cannot drive the aluminum alloy profile to shake up and down or left and right, so that some local areas of the aluminum alloy profile may not fully contact the heat source, resulting in incomplete and thorough heat treatment, further affecting the overall performance of the aluminum alloy profile, and reducing the product qualification rate and use efficiency.

[0006] Thirdly, the existing heat treatment equipment has poor gas circulation in the furnace and low heat transfer efficiency, which on the one hand slows down the heating speed of the aluminum alloy profile and prolongs the heat treatment period, and on the other hand, the temperature distribution in the furnace is uneven, which easily causes local overheating or insufficient heating, and the waste gas or residual heat generated during the heat treatment process cannot be timely discharged or recycled, which not only affects the heat treatment effect but also causes energy waste, which does not meet the development trend of energy saving and environmental protection.

[0007] Fourth, the sealing performance of the existing equipment is poor, and heat loss is easy to occur during heat treatment, which not only increases energy consumption, but also is difficult to maintain the stability of the furnace temperature, thereby affecting the precise control of the heat treatment process; at the same time, the positioning mechanism of the existing equipment is not reasonable, and the adaptability of different specifications and shapes of aluminum alloy profiles is poor, the positioning is not firm enough, and the offset or shaking is easy to occur during heating or moving, which affects the heat treatment precision.

[0008] Fifth, the structure of the existing heat treatment equipment is complex, the operation is cumbersome, the maintenance cost is high, and the intelligent degree is low, which is difficult to realize the precise regulation and automatic operation of the heat treatment process parameters, and is not conducive to improve the production efficiency and the consistency of product quality.

[0009] In view of the problems existing in the prior art, the present application provides a heat treatment equipment and method for aluminum alloy profile machining, which optimizes the overall structure design of the equipment, integrates rotation, translation, shaking, gas circulation and other functions, realizes uniform, omnidirectional and efficient heat treatment of aluminum alloy profiles, and improves the sealing performance, adaptability and intelligent level of the equipment, solves the defects existing in the prior art, and meets the development needs of modern aluminum alloy profile machining industry in high quality, high efficiency, energy saving and environmental protection.

[0045] Example 2 A method for using a heat treatment device for processing aluminum alloy profiles, employing the device described in Example 1, includes the following steps: S1: Equipment initialization preparation: First, check the connection of each component of the equipment to ensure that each component is firmly connected and there is no looseness; start the battery 20 through the control panel to power the equipment, and at the same time set the heat treatment process parameters through the control panel: set the heating temperature to 200℃, the heat holding time to 30min, the rotation speed to 15r / min, the translation speed to 3mm / s, and the vibration frequency to 3 times / min.

[0046] S2: Clamping and positioning of aluminum alloy profile: Operate electric cylinder 7 to move sealing plate 23 upward and open through groove 24 on the right side of outer shell 1; put the aluminum alloy profile to be heat treated into the rotating tube 29 from the right opening of the right shell 10, adjust the position of the aluminum alloy profile so that it is located on the central axis of the rotating tube 29; control the three electric push rods 33 to extend synchronously through the control panel, drive the positioning plate 32 to move towards the aluminum alloy profile until the anti-slip rubber pad is tightly attached to the outer surface of the aluminum alloy profile, and firmly clamp and position the aluminum alloy profile.

[0047] S3: Sealing and preheating: After the aluminum alloy profile is clamped, the control cylinder 7 reverses its movement, causing the sealing plate 23 to move downwards and close the through groove 24; the spiral heating tube 19 is started to preheat the inside of the outer shell 1. The temperature sensor detects the internal temperature in real time and transmits it to the control panel. When the temperature reaches 200℃, the spiral heating tube 19 enters the heat preservation state.

[0048] S4: Rotation and translation heat treatment: Start the drive motor 9 to drive the worm gear 31 to rotate, which in turn drives the rotating tube 29 to rotate through the worm wheel 30, thereby driving the aluminum alloy profile to rotate synchronously; at the same time, start the servo motor 14 to drive the lead screw 26 to rotate, which drives the right housing 10 to move left and right through the nut 25, the electric telescopic rod 13 and the cross plate 11, thereby driving the aluminum alloy profile to slide left and right between the two spiral heating tubes 19, realizing the combined motion of rotation and translation.

[0049] S5: Shaking All-round Heat Treatment: The electric telescopic rod 13 is controlled to periodically extend and retract at a shaking frequency of 3 times / min, which drives the right shell 10 to move up and down, thereby causing the aluminum alloy profile to shake up and down between the two spiral heating tubes 19, so as to achieve all-round heat treatment.

[0050] S6: Gas circulation assisted heat treatment: Start the blower 5 to blow filtered external air into the outer shell 1; when the right shell 10 moves left and right, the first docking rod 8 and the upper U-shaped plate 22 slide left and right through the side plate 12; when the nut 25 slides left and right, it drives the second docking rod 27 and the lower U-shaped plate 22 to slide left and right; when the U-shaped plate 22 slides, it draws the gas in the outer shell 1 through the suction hole 21, forming a gas circulation flow in conjunction with the blower 5.

[0051] S7: End of heat preservation and cooling: After the heat preservation time reaches 30 minutes, turn off the spiral heating tube 19; keep the blower 5, drive motor 9, servo motor 14 and electric telescopic rod 13 running to cool the aluminum alloy profile with air. When the temperature drops to room temperature, turn off all operating components.

[0052] S8: Removal of aluminum alloy profile: Operate electric cylinder 7 to move sealing plate 23 upward and open through groove 24; control electric push rod 33 to retract, causing positioning plate 32 to separate from aluminum alloy profile; remove the heat-treated aluminum alloy profile from rotating tube 29.

[0053] The method described in this embodiment for heat treatment of aluminum alloy profiles can achieve uniform and all-round heat treatment. The mechanical properties of the heat-treated aluminum alloy profiles, such as hardness and strength, are significantly improved, and the performance is uniform and consistent. The product qualification rate reaches more than 98%, the heat treatment efficiency is increased by more than 30% compared with existing equipment, and energy consumption is reduced by more than 20%.

The specific settings are as follows: the heating temperature is set to 300℃, the holding time is set to 40min, the rotation speed is set to 20r / min, the translation speed is set to 2mm / s, and the shaking frequency is set to 2 times / min.

[0055] The method described in this embodiment can also achieve uniform and all-round heat treatment of aluminum alloy profiles. The mechanical properties of the heat-treated aluminum alloy profiles meet the requirements of high-end industrial products, the product qualification rate reaches more than 99%, the heat treatment efficiency is increased by more than 25% compared with existing equipment, and energy consumption is reduced by more than 18%.
