Dual-hook steel plate pile continuous roll bending forming method

Abstract

The invention discloses a dual-hook steel plate pile continuous roll bending forming method. The method specifically comprises the following steps that a steel plate pile locking notch dual hook comprises a male hook A and a female hook B, a bottom plate C is connected between the male hook A and the female hook B, and an inclined plate D is connected between the male hook B and the bottom plate C. The dual hook steel plate pile continuous roll bending forming method specifically comprises the following steps of S1, longitudinal strip steel shearing; S2, uncoiling and leveling; S3, shearing and butt welding; S4, continuous roll cold bending forming, wherein strip steel passes through a forming unit and is subjected to continuous multi-angle changes through multiple specially-designed roller pieces until a required shape section is formed; and S5, cutting off, wherein the strip steel passes through the forming unit and is subjected to continuous multi-angle changes through the multiplespecially-designed roller pieces until the required shape section is formed, after production, the strip steel is flatly cut open, after cutting open, a male hook and a female hook do not deform, or twist, the hooks are connected and are not separated, and supporting does not generate deform.

Description

technical field [0001] The invention relates to the technical field of construction steel materials, in particular to a double-hook steel sheet pile continuous roll bending forming method. Background technique [0002] Steel sheet piles are widely used in the construction of wharves and islands. The shape and strength of the joints used to connect steel sheet piles have become a subject of research in the industry. The double-hook production process of the left lock (male hook) and right lock (female hook) for U-shaped or other shapes, not only connects the male hook and the female hook to produce, cuts straight from the center after production, and after cutting For the male hook and the female hook, it solves the technological problem that the single hook cannot be produced by roll bending, and also solves the difficulty of connecting the steel sheet piles and greatly improves the strength of the steel sheet pile connections. [0003] Steel sheet pile is a product made of...
