Abstract
Official abstract text for this publication.
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.
