Aluminum Alloy Locking Clip

This product is a high performance block mill made of 7075 aluminum alloy machined by CNC Milling. an overall symmetrical U-shaped or semicircular structure with an inner arc-shaped cavity in the center for winding and fastening components such as axes, rods or handles; Two through holes are provided at each end to facilitate fastening and positioning by bolts or bolts. The arrangement of the opening is useful to ensure a uniform distribution of the lifting force and to avoid the local stress concentration. The general contour lines are smooth and the edges are treated with gentle transitions, which improves not only the mountability but also the structural life.

Step 1: We use aluminum 7075 alloy sheet for cutting, and cut suitable blanks according to the external dimensions and processing allowance of the locking buckle; It then enters the phase of hard machining, in which the excess material is quickly removed with the help of a high-stiffness CNC milling machine. The rough contour of the semicircle and the pre-drilling holes for both ends are milled, while the shape and position errors are controlled after sharp mechanization, to reduce the cutting stress and the risk of deformation for precision mechanization.

Step 2: After the hard machining, carry out the aging treatment to release the internal tension and then enter the precision machining. Adoption of ultra-precision machining of CNC milling machines with high precision: The inside of the semicircle is well wound around the curved surface, to cut and form once, ensuring roundness and roughness and ensuring alignment with the axis; The mounting openings at both ends follow a process consisting of a filling hole, which is used in conjunction with a dedicated thread milling cutter to process M8 × 1.25 threads. Throughput, profile angle and diameter of the passage are strictly controlled to ensure the stability of the rosed connection; Simultaneous precision milling of the installation plans at both ends to ensure ensure even force distribution after the locking buckle is installed.

Step 3: After the precision machining is finished, we will conduct a full inspection and deburring treatment on the product, remove flying edges and markings of the machining tool on the edges, thread holes and curved surfaces to avoid scratches and disruption of assembly; It then enters the process of surface treatment, in which a uniform and delicate matte surface is formed by sandblasting, to eliminate the mechanization features and improve the surface adhesion.

Step 4: Finally, the anodizing treatment is carried out to form a dense oxide film on the surface of the aluminum alloy, which enhances the wear resistance, significantly improves the corrosion resistance and insulation properties of the product.
