Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] Such as Figure 1-6 shown.

[0052] A Z-shaped steel sheet pile, whose cross-section is a Z-shaped structure, it is provided with two locks A, B and two waists C, such as figure 1 As shown, it can be used Figure 3-6 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 molds of each process, please refer to Figure 3-6 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:

[0053] 1. Slitting strip steel

[0054] The hot-rolled coil is slit into the width designed by the process on the slitting unit

[0055] 2. Uncoiling and leveling

[0056] The hot-rol...

Abstract

The invention discloses a manufacture method of a Z-shaped steel sheet pile through continuous cold roll forming by continuously rolling and forming with a cold bending unit and distributing preliminary shafts at both sides of a central shaft. Web plates are continuous so as to greatly improve the modulus and the flexible rigidity of a cross section and fully exert the mechanical characteristic of the cross section. The manufacture process takes great effects in aspects, such as controlling the quality of the cold-bent Z-shaped steel sheet pile, improving the matched accuracy and the connection strength of the preliminary shafts of the steel sheet pile, and the like. The invention controls the product size and overcomes the defects generated in the processing process by performing the preliminary shafts of the cold-bent Z-shaped steel sheet pile and wholly forming the Z-shaped steel sheet pile.

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 Z-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'...
