Abstract

Se proporciona un dispositivo de mandril que puede sostener una pieza de trabajo de manera apropiada. Un dispositivo de mandril incluye: un mandril cilíndrico que incluye una primera parte de contacto en un primer lado en la dirección axial y una segunda parte de contacto en un segundo lado, y configurado para sostener una pieza de trabajo similar a una barra o varilla; un cilindro exterior tubular que incluye, en el primer lado, una parte de restricción configurada para restringir el movimiento axial del mandril al colindar la primera parte de contacto; y un manguito proporcionado en una manera axialmente movible en el lado periférico interior del cilindro exterior, y que incluye, en el primer lado, una parte de prensado accionada axialmente para colindar en la segunda parte de contacto. El mandril incluye una primera cara ahusada en la primera parte de contacto, y una segunda cara ahusada en la segunda parte de contacto. Un primer ángulo entre la primera cara ahusada y un eje central es equivalente a un segundo ángulo entre la primera cara ahusada y el eje central, o es más pequeño que el segundo ángulo. Un ángulo entre una cara ahusada de restricción de movimiento en la parte de restricción en el eje central, un ángulo entre una cara ahusada de prensado de la parte de restricción y el eje central, y un ángulo entre la segunda cara ahusada y el eje central son equivalentes entre sí.
