Abstract
Un dispositivo empujador incluye un dispositivo de cilindro y un mandril empujador. El dispositivo de cilindro incluye un eje de cilindro. El mandril empujador está fijado al extremo de punta del eje del cilindro. El extremo de punta del mandril empujador está apoyado en el extremo trasero de una placa metálica. El área de sección transversal Sp del mandril empujador y el área de sección transversal Sb de la placa metálica satisfacen la Expresión (1). La longitud Lp del mandril empujador y el área de sección transversal Sp del Mandril Empujador satisfacen la Expresión (2). La distancia de movimiento Lc del extremo de punta del eje del cilindro durante la perforación y rodadura y el diámetro exterior Dc del eje del cilindro satisfacen la expresión (3). Por lo tanto, el dispositivo empujador puede impedir la desviación del espesor de pared de la parte de extremo de punta de una estructura hueca producida.
