A kind of forming method of hot-rolled U-shaped steel sheet pile

Abstract

The invention discloses a forming method of hot-rolled U-shaped steel plate piles, and belongs to the technical field of formation of metal plastic processing. The forming method comprises the following steps: firstly, a last frame K1 hole is discarded in a traditional hot-rolled U-shaped steel plate pile finishing mill unit; a locking port forming device, provided by the invention, is mounted to replace the last frame K1 hole far from a K2 hole outlet; the locking port forming device consists of a set of horizontal rollers and a set of inclined rollers; roller gaps of the horizontal rollers and positions and dip angles of the inclined rollers are all controllable; the horizontal rollers of the locking port forming device are mounted in front of the inclined rollers of the locking port forming device; the rotating speed of upper and lower rollers of the horizontal rollers of the locking port forming device is consistent with the rotating speed of upper and lower rollers of a K2 hole; the rotating speed of the inclined rollers of the locking port forming device is equal to the rotating speed of upper rollers of the K2 hole; and then, the hot rolling of the U-shaped steel plate piles is performed. The method can effectively improve the locking port formation precision of the U-shaped steel plate piles, and improves the yield of the U-shaped steel plate piles.

Description

Technical field: [0001] The invention belongs to the technical field of metal plastic processing and forming, and in particular relates to a forming method of hot-rolled U-shaped steel sheet piles. Background technique: [0002] The application of hot-rolled U-shaped steel sheet pile projects is becoming more and more extensive, covering the entire construction industry including construction engineering, water conservancy engineering, road traffic engineering, environmental pollution control engineering and disaster prevention engineering. U-shaped steel sheet piles can be used in temporary structures and permanent structures. Unique advantages such as less land. [0003] As an important metal material in the field of modern foundation and underground engineering, U-shaped steel sheet piles can be divided into hot-rolled steel sheet piles and cold-formed thin-walled steel sheet piles according to different processing techniques. Cold-formed thin-walled steel sheet piles u...

Problems solved by technology

However, U-shaped steel sheet piles have complex dimensions and strange shapes of curved locks on both sides. They are hot-bent profiles with complex sections. The deformation process of the rolled piece is complicated and the quality control is difficult. It requires high requirements for the entire rolling process equipment, which poses a challenge to product development and production. Control makes it difficult
