Abstract
A transfer machine for cold plastic deformation and/or chip removal of at least one tubular profile has a base, a mounting table, a rotary table, and a plurality of electromechanical work units installed on the mounting table. Each electromechanical work unit has a first advance group having a first advance motor, a first advance recirculating ball screw, a first advance nut and a first tubular stem. The first advance recirculating ball screw is moved by the first advance motor. The first advance nut is engaged by the first advance recirculating ball screw. The first tubular stem, defining advancement and/or positioning of a first tool holder element, is engaged to and made integral with the first advance nut.
Claims15
An electromechanical work unit comprising a first advance group, wherein the first advance group comprises:
- a first advance motor;
- a first advance recirculating ball screw moved by the first advance motor and extending along a first advance screw axis, the first advance screw axis being substantially orthogonal to a mounting table;
- a first advance nut engaged by the first advance recirculating ball screw and translatable along the first advance screw axis, and
- a first tubular stem extending between a first stem proximal end and a first stem distal end, the first stem proximal end being engaged to the first advance nut and made integral therewith, the first stem distal end being suitable for defining an advancement and/or a positioning of a first tool holder element,
- wherein the first advance motor is a hollow shaft motor, and
- wherein the first advance motor, the first advance recirculating ball screw, the first advance nut and the first tubular stem are coaxial.
