为了解决承载结构件中的设计问题,挤压制品的需要量正在逐渐增多。通常,挤压制品的断面多为空心的或内部有复杂筋条网络,以保证有高的刚度和适当的应力分布。但是这种型材有一个问题,即在水压机上进行水淬常常发生困难,随后的矫直操 In order to solve the design problems in the bearing structure, the demand for extruded products is gradually increasing. In general, the cross-section of the extruded product is mostly hollow or has a complex network of internal ribs to ensure high stiffness and proper stress distribution. However, there is a problem with this profile, which is that it is often difficult to perform water quenching on a hydraulic press, followed by straightening
