Abstract

The invention discloses a manufacturing method for steel coil packaging protection corners. The manufacturing method comprises the steps that S1, sample preparation is carried out, wherein a coiled material is divided, and narrow steel belt coils are formed; S2, uncoiling is carried out, wherein the divided narrow steel belt coils are put on an uncoiling machine to be uncoiled, and steel belt strips are formed; S3, shearing is carried out, wherein the steel belt strips are sheared, blanks are formed, and the blanks are precoated steel plates; S4, bending is carried out, wherein the blanks arebent; and S5, rolling forming is carried out, wherein the bent blanks are subjected to rolling forming, and the protection corners are formed. According to the manufacturing method for the steel coilpackaging protection corners, the precoated steel plates are adopted to be manufactured into the protection corners, a spraying process in the later period in the cold-rolled sheet production processis avoided, the machining of the steel coil packaging protection corners is facilitated, pollution is reduced, the cost is saved, the physical and psychological health of workers is protected, the defects that the strength is not enough and the tenacity is not good when plastic is used for preparing the steel coil packaging protection corners are avoided, and the manufactured steel coil packagingprotection corners are high in strength and anti-rust capacity and good in attractiveness.

Description

technical field

[0001] The invention belongs to the technical field of steel coil packaging, in particular, the invention relates to a method for manufacturing corner protectors for steel coil packaging. Background technique

[0002] Steel coil packaging corner protector is an auxiliary product used in the packaging, transportation, lifting and use of steel coils in the metallurgical industry. It can effectively protect the edges of steel coils from damage or collapse.

[0003] Steel coil packaging corner protectors play an important role in protecting steel coils, especially high-grade steel home appliance panels and automobile panels during transportation. The steel coil packaging corner protector must not only have a certain strength to protect the edge of the steel coil from damage due to transportation, but also have corrosion resistance, not easy to rust, and at the same time have aesthetics.

[0004] The materials used to prepare steel coil packaging corner protector...
