[0037] The material storage platform is a slanted frame structure with an inclination of 2 to 5°. The workpiece steel pipe or oil well pipe or drill pipe rolls on the beam equipped with anti-noise nylon backing plate on the surface. The outlet end is designed with a material blocking device. Manual assistance during feeding can easily make the workpiece steel pipes or oil well pipes or drill pipes neatly arranged and distributed. The material storage platform is equipped with an eccentric wheel structure. For φ60~φ139.7, adjust the eccentric wheel at different angles to make the material turn over The device can only turn over one material at a time.
[0038] The workpiece steel pipe or oil well pipe or drill pipe is sent to the first station by the material rack of the storage table—aligned with the positioning roller table. The positioning roller table is composed of four rollers and is equipped with a material receiving switch. The rollers at both ends are The motor drives ...
