Abstract

A multiple clamp type stretching and forming machine is composed of multiple material clamping mechanisms (1), multiple material stretching mechanisms (2) and a frame (3). The material clamping mechanism (1) is composed of a material clamping frame (7), material clamping blocks (8, 9) and a hydraulic cylinder (6) for clamping material. The two sides of the frame (3) are arranged with a row of multiple material clamping mechanisms (1), respectively. The material clamping frame (7) of each material clamping mechanism (1) is provided with one or two connecting holes (5), which connect with one or more material stretching mechanisms (2) through a universal push-pull mechanism (4). The stretching and forming machine can improve the utilization ratio of the material, and reduce the manufacturing cost.
