Abstract
En el presente documento se proporciona un aparato de laminación oblicua con el cual se pueden evitar los defectos de forma en las porciones no estacionarias en los extremos delanteros y traseros de un armazón para tubos sin costura. El aparato de laminación oblicua incluye: un tren de laminación con punzonador oblicuo para laminación con punzonador y un tren de diámetro externo oblicuo después del tren de laminación con punzonador oblicuo, donde el aparato de laminación oblicua satisface las siguientes fórmulas (1) y (2), 3 × (1,2 PO + 2 G) & 1,2 PO + 2 G > DS & en donde LS es la distancia, en mm, entre una zona de laminación de los rodillos de laminación con punzonador y una zona de laminación de los rodillos de laminación de diámetro externo, DS es el espacio de los rodillos entre los rodillos de laminación de diámetro externo, PO es el diámetro exterior, en mm, de un punzón, G es el espacio, en mm, entre el punzón y los rodillos de laminación con punzonador, BL es la longitud, en mm, de una barra, y DB es el diámetro exterior, en mm, de la barra.
