Low-elasticity structure line and manufacturing method thereof

Abstract

The invention discloses a low-elasticity structure line and a manufacturing method of the same. The low-elasticity structure line is a three-dimensional curved metal wire in a columnar space range, the length of the cross section of the columnar space is less than or equal to 2mm, and the elastic elongation percentage of the three-dimensional curved metal wire is less than 2%. The low-elasticity structure line overcomes the defects of existing straight metal wire structure line products, has higher adhesive force with rubber (or plastic) materials, meanwhile, low relaxation performance of a whole part is guaranteed, and the low-elasticity structure line has better capacity of carrying mortar grinding materials and capacity of resisting cutting tension fluctuation.

Description

technical field [0001] The invention relates to a low-elastic structural wire used for rubber (or plastic) skeleton reinforcement material or a wire saw for cutting hard material and a manufacturing method thereof. Background technique [0002] At present, most of the metal wires used for rubber (or plastic) skeleton reinforcing materials, or wire saws for cutting hard materials are linear steel wires (straight steel wires). If the chemical bonding between the straight steel wire and the rubber (or plastic) is poor, the steel wire will easily loosen in the rubber (or plastic), thereby losing the skeleton reinforcement. During the wire saw cutting process, the ability of the straight steel wire to carry the chip mortar is limited, which limits the further improvement of the cutting speed. [0003] The performance of the deformed wire bent on two planes is improved compared with that of the straight steel wire, but because the projected area of ​​the metal wire per unit lengt...

AI Technical Summary

Problems solved by technology

If the chemical bonding between the straight steel wire and the rubber (or plastic) is poor, the steel wire will easily loosen in the rubber (or plastic), thus losing the skeleton reinforcement

During the wire saw cutting process, the ability of the straight steel wire to carry the chip mortar is limited, which limits the further improvement of the cutting speed

[0003] The performance of the deformed wire bent on two planes is improved compared with that of the straight steel wire, but because the projected area of ​​the metal wire per unit length on the cross section is still limited, the performance improvement is relatively limited

Although the straight steel wire can be helically deformed to make it have the characteristics of a spring, the elastic extension of the wire is quite large, which still cannot meet the low elongation requirements of some products.
