Embodiment Construction
[0050] The present invention will be further described below in conjunction with the 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 has two locks A, B and two waists C, such as figure 1 As shown, it can be used Figure 3-6 The method shown and the continuous rolling die are continuously cold-formed. The continuous deformation process of the steel plate during the forming process is as figure 2 Shown. Refer to the roll forming mold for each process Figure 3-6 To design, as the key to continuous cold bending is the selection of deformation process and method, and deformation angle. The specific manufacturing process includes:
[0053] 1. Slitting strip steel
[0054] The hot-rolled coil is slit to the width of the process design on the slitting unit
[0055] 2. Uncoiling and leveling
[0056] The hot-rolled coil after slitting is opened on the decoiler on the cold bending forming unit,...
