Direct-drive motor-driven rolling composite unit

Abstract

This utility model relates to a direct-drive motor-driven rolling composite unit, comprising an upper tool holder and a lower tool holder vertically spaced on a tool holder, with adjustable spacing between them. A lower tool shaft is vertically rotatable on the lower tool holder, and a lower mounting plate is located at the lower end of the lower tool holder. A lower reducer is vertically mounted on the lower mounting plate, with its input end connected to a lower servo motor and its output end connected to the lower tool shaft. A lower rolling cutter disc is located at the upper end of the lower tool shaft. An upper tool shaft is vertically rotatable on the upper tool holder, and an upper rolling cutter disc is located at the lower end of the upper tool shaft. This unit features a reasonable structural design, a direct-drive motor design, high transmission efficiency, and high transmission accuracy.
