Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045]like Figure 1-8 shown.

[0046] A U-shaped steel sheet pile, whose cross-section is U-shaped, and is symmetrical about the center, and each side is connected upwards with a waist B, a leg C and a lock A, such as figure 1 As shown, it can be used Figure 3-8 Shown is the method and continuous rolling die for continuous cold roll forming. The continuous deformation process of the steel plate during the forming process is as follows: figure 2 shown. For the roller forming dies of each working step, please refer to Figure 3-8 To be designed, the key to continuous cold bending is the selection of the deformation process and method, and the deformation angle. The specific manufacturing process includes:

[0047] 1. Slitting strip steel

[0048] The hot-rolled coil is slit into the width designed by the process on the slitting unit.

Abstract

The invention discloses a roll type continuous cold-bending forming fabricating method for a U-shaped steel sheet pile, which comprises the steps of: carrying out continuous rolling and forming by using a cold-bending machine unit and continuously overlapping lateral fore shafts to form a steel structure of sheet pile walls. The process plays an important role in controlling the product quality and improving the mate precision and the connection strength of the fore shafts of the steel sheet pile. The U-shaped steel sheet pile has rich specifications and models, and the most economical and reasonable cross section can be selected according to the actual situation of a project to realize the optimization of engineering design; and compared with a hot rolled steel sheet pile with the same performance, the U-shaped steel sheet pile saves materials of 10% to 15%, which greatly reduces the construction cost.

Description

technical field [0001] The invention relates to a production method of metal building materials, in particular to a manufacturing method of cold-bending forming of steel sheet piles, in particular to a manufacturing method of roll-type continuous cold-bending forming of U-shaped steel sheet piles. Background technique [0002] As we all know, steel sheet piles began to be produced in Europe at the beginning of the 20th century, and were quickly widely used all over the world, especially in developed industrialized countries. In the 1950s, my country first imported and used it from the former Soviet Union by the Bridge Bureau of the Ministry of Railways in the construction of railway bridge cofferdams. Due to the influence of cheap land resources and human resources, and domestic production is basically in a blank state, the application and development of steel sheet piles as metal building materials in my country is still very slow. With the rapid development of my country'...
