Aluminum plate stretcher


Thick plate hot-rolled aluminum alloy will produce large residual stress after quenching. The residual stress will cause the plate to deform during mechanical processing. At the same time, the residual stress will increase the fatigue fracture sensitivity of the material, shorten the service life, and even cause the material to be scrapped. . The stretching machine designed and developed by our company uses the hydraulic system of the stretching machine to provide tension to stretch the material to a certain elongation rate, and then maintains the pressure for a period of time to eliminate the residual stress of the aluminum plate to ensure the flatness of the hot-rolled aluminum plate and eliminate the problem due to The stress generated inside the aluminum sheet during the rolling process is released.
