This bicycle seat buckle is made of aluminum alloy 6061 and has a circular structure overall. The surface was anodized to show a uniform and glossy blue-green metallic gloss; The outer ring is a smooth cylindrical surface, and there is a longitudinal section on the inside to form an elastic opening and closing structure of the closure, which facilitates the quick assembly and dismantling of the seat post. There are small projections in the lower part of the two ends to improve the stability of the fastening. The structure is compact, light and durable, aesthetic and functional, suitable for quick closing and adjusting various tube of the bicycle seat.
Step 1: In the processing phase, we use aluminum alloy rods 6061 as raw material. First, we use a CNC cutter to cut the material accurately to ensure that the blank dimension is checked within ± 0,1 mm of the design error of the drawing.
Step 2: After the blank is clamped onto the CNC machining center, it enters the High Precision CNC Milling process: First of all, use a large diameter flat end knife, to roughly milling and quickly forming the annular contour and the lower assembly seat; Replace the cutting tool with medium diameter to the inner wall, milling the outer circle and the opening leg of the annular body semi-precisely and evenly reserving the manufacturing concession.
Step 3: Use a small diameter tool to fine milling the opening space, the position of the mounting hole and the edge radius for precision machining. Strictly control the roundness, coaxiality of the hole and opening tolerance to ± 0.01 mm, to ensure a precise closure and a fluid assembly and disassembly of the locking closure; After treatment, ultrasonic cleaning and manual shredding are performed to precisely remove the debris and cutting edges. The entire process uses precision milling technology optimized for aluminum alloy in combination with high-pressure cooling, Thermal deformation is effectively avoided.
Step 4: Entry into the treatment phase of the anodizing surface: First, the surface is cleaned by chemical degreasing and washed with acid, then a dense oxide film is formed in the sulfuric acid electrolyte. Finally, it is dyed according to the color of the final product specified by the customer, which not only retains the metallic consistency, but also significantly improves the corrosion and wear resistance of the closure.
