Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of suturing, and in particular relates to a curved needle. Background Art
[0002] TKAS galvanized and aluminum wire can produce surface galvanized and aluminum with a thickness of 0.38-3.5 in full range. It includes high-grade sheet products such as automobile outer panels, and customers have extremely high requirements for the quality of the plate surface; the temperature of the steel strip after galvanizing and aluminum coating reaches 480-750℃. It is easy to cause: the direct contact between the steel strip and the steel roller will cause the surface to be flowery, the uneven cooling of the surface coating will cause the coating to peel off, and the steel strip is soft and easily scratched by impurities attached to the surface of the steel roller. So that the material is downgraded and scrapped. We wrap the surface with high temperature resistant cloth for protection. The cloth is wrapped and then sutured. Since the artificial suture line will crack after a certain period of production, but still meet the production needs, it is often necessary to supplement the suture manually to avoid waste. Because the cloth protects the steel roller, the suture is operated on the curved surface, and the ordinary straight needle cannot guarantee the effective closure of the force and the contact port of the cloth. For this reason, a curved needle is improved and designed, so that personnel can quickly complete the curved surface suture, which is efficient and avoids more time waste, protects the flatness of the steel plate surface, and is safer.
