A process for manufacturing screws and a device for actuating the process |
摘要 |
A device for manufacturing a screw (2) comprises a cylindrical support (3) having a horizontal axis (x-13 x)and being rotatable there about. A straight bar (7) is wound spirally about the support (3). The bar (7) is constrained to a guide (8) and can perform movements in a parallel direction to the axis (x-x) of the support (3) on command of a translator provided with an endless screw (14). The process for manufacturing the screw comprises controlling axial movement of the guide (8) in a predetermined rapport with the rotation of the support (3). The invention is particularly applicable in the manufacture of a screw for a screw conveyor. |
