Abstract

The invention belongs to the technical field of sewing machine processing, and relates to a sewing machine component, in particular to a sewing machine needle bar support body. The needle bar support body is made of ceramic skeleton reinforced aluminum matrix composite material, which includes superhard wear-resistant particles with a volume ratio of 5‑10%, 20‑30% ceramic skeleton and 60‑75% The aluminum alloy matrix is ​​compounded by pressure infiltration, and the aluminum alloy matrix is ​​composed of the following mass percentage components Mg2.2‑4.2%, Si1.2‑2.0%, Cr0.35‑0.8%, Cu0.12‑0.18 %, Mn0.12‑0.2%, Zn0.15‑0.25%, Ni0.05‑1.5%, B0.02‑0.4%, Zr0.05‑0.1%, Sc0.06‑0.1%, and the balance is Al. The needle bar branch body has good comprehensive properties, especially good wear resistance.

Description

technical field [0001] The invention belongs to the technical field of sewing machine processing, and relates to a sewing machine component, in particular to a sewing machine needle bar support body. Background technique [0002] The needle bar branch belongs to the accessories of the sewing machine transmission device, which plays the role of transmitting the power of the movement to the working mechanism. After long-term service, the main damage forms of the needle bar support body are fatigue fracture, excessive wear, deformation and so on. Therefore, in the early stage of design, the working conditions of the needle bar support require that the linkage rod have high strength, wear resistance and fatigue resistance, and also require sufficient rigidity and toughness. [0003] At present, in the traditional processing technology of the needle bar support, its material generally adopts quenched and tempered steel, aluminum alloy and the like. Among them, the aluminum allo...
