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...
