Technical Field

[0001] The present application relates to the field of anodizing of aluminum alloy tubes, and in particular to an anodizing process production line for aluminum alloy tubes. Background Art

[0002] Anodizing is an electrochemical treatment process that uses electric current to cause oxidation reaction on the surface of aluminum and its alloys to form a dense oxide film. This oxide film has excellent corrosion resistance, wear resistance, decorative and insulating properties, and can significantly improve the service life and appearance quality of aluminum alloy tubes.

[0003] As an important industrial material, aluminum alloy tubes are widely used in aerospace, construction, automobile, electronics and other fields. However, aluminum alloy itself has certain deficiencies in hardness and wear resistance, which limits its application in some high-demand occasions. Therefore, it has become an important technical means to treat the surface of aluminum alloy tubes through anodizing process to meet the requirements of material performance in different fields.

[0004] The aluminum alloy tube anodizing production line includes the steps of hanging, electrolysis, water washing, etc. In the prior art, the electrolytic tank and the water washing tank are separated, and special equipment is required in the middle for lifting. The equipment can only lift one group of workpieces at a time. After one group of workpieces completes all the steps of processing and unloading, a new group of workpieces can be lifted. The waiting time is long and the processing efficiency is low. Summary of the invention

[0006] The anodizing process production line for aluminum alloy tubes provided in this application adopts the following technical solution: A production line for anodizing an aluminum alloy tube comprises a platform, a fixed frame, a gantry, a lifting frame, a support frame and a hanging frame. A plurality of processing grooves are arranged at intervals along the length direction of the platform at the upper end of the platform. The fixed frame is fixedly connected to the upper end of the platform, and the length direction of the fixed frame is parallel to the length direction of the platform. The gantry is slidably connected to the fixed frame, and the sliding direction of the gantry is parallel to the length direction of the fixed frame. The lifting frame is slidably connected to the gantry, and the sliding direction of the lifting frame is vertical, and the length direction of the lifting frame is parallel to the length direction of the processing groove. The upper end of the support frame is fixedly connected to the lifting frame, and the lower end of the support frame is detachably connected to the hanging frame. The length of the hanging frame is greater than the length of the processing groove, and the hanging frame is used to hang a workpiece.

[0007] By adopting the above technical solution, the hanger is connected to the support frame, the movement of the gantry drives the hanger to move along the length direction of the fixed frame, and the movement of the lifting frame drives the hanger to move along the vertical direction, so that the hanger can be moved into the processing tank according to needs. The hanger and the support frame are detachable. When the workpiece needs to be immersed in the processing tank for a period of time, the support frame is separated from the hanger, which is convenient for transporting other hangers and improving processing efficiency.

[0008] Preferably, the hanging bracket includes a mounting rod, a connecting rod and a hanging rod, the two ends of the connecting rod are fixedly connected to the mounting rod and the hanging rod respectively, the mounting rod is arranged above the hanging rod, the length of the hanging rod is greater than the length of the processing groove, the hanging rod is used to hang the workpiece, and the support frame is detachably connected to the mounting rod.

[0009] By adopting the above technical solution, the workpiece is hung on the hanging rod, and the hanging rod is placed on the platform, so that the workpiece is stably immersed in the processing tank, and the mounting rod is above the hanging rod. The position of the mounting rod is convenient for connecting the support frame to improve the processing efficiency.

[0010] Preferably, the support frame includes a connecting plate and a support block, and two support frames are provided. The upper ends of the two connecting plates are respectively fixedly connected to the two ends of the lifting frame, and the distance between the two connecting plates is greater than the length of the mounting rod.

The support groove penetrates the support block along the length direction of the lifting frame, and the support groove is used for the mounting rod to be embedded.

[0011] By adopting the above technical solution, when the support frame and the hanging frame need to be connected, the gantry truck and the lifting frame together control the support block to move to the bottom of the mounting rod, and the lifting frame moves upward to drive the hanging frame to move, which is convenient for connection and separation and improves processing efficiency.

[0012] Preferably, the distance between two opposite groove walls of the supporting groove decreases as it moves away from the lifting frame.

[0013] By adopting the above technical solution, the groove wall of the support groove has a guiding function, which makes it easy for the installation rod to stably enter the support groove and connect with the support block, thereby improving processing efficiency.

[0015] By adopting the above technical solution, when the lifting frame drives the hanging bracket to move upward to the correct position, the gantry truck starts to drive the hanging bracket to move along the length direction of the platform. During the movement, due to inertia, the installation rod may be skewed in the support groove, and the support block and the hanging bracket are unevenly stressed and easily damaged. The limit block limits the installation rod, so that when the gantry truck starts, the installation rod is not easy to be skewed, thereby extending the service life of the device.

[0019] By adopting the above technical solution, when the mounting rod abuts against the groove wall of the supporting groove, the lifting frame moves upward, the telescopic tube contracts, and the pressure difference causes the limit block to slide outward until the exhaust channel is connected to the limit groove. The limit block limits the mounting rod, thereby improving the stability of the mounting rod and extending the service life of the device. The gas discharged from the exhaust channel is directed toward the workpiece, reducing water stains on the outer surface of the workpiece and improving the processing quality.

[0020] Preferably, it also includes a second one-way valve, an air intake channel is provided at one end of the limit block away from the bottom of the limit groove, and an end of the air intake channel close to the bottom of the limit groove is used to connect to the second air channel, and the sliding of the limit block is used to control the connection between the air intake channel and the second air channel, and the second one-way valve is fixedly connected to the inner wall of the air intake channel.

[0021] By adopting the above technical solution, when the gantry truck drives the workpiece to move to the correct position, the lifting frame slides downward, the telescopic tube extends to inhale air, and the limit block slides into the limit groove due to the air pressure difference. The air inlet channel is connected with the second air channel, and the gas enters the telescopic tube through the second one-way valve, which is convenient for controlling the automatic reset of the limit block, making it easy for the mounting rod to separate from the support block, thereby improving the processing efficiency.

[0024] Preferably, both ends of the hanging rod are fixedly connected with stabilizing blocks, and the lower end of the stabilizing block is used to abut against the buffer seat.
