A finishing device for titanium alloy convex tubes

Abstract

This invention relates to a finishing device for titanium alloy ribbed tubes, comprising a worktable, a finishing mold, supports, a lifting mechanism, a lead screw, a stepless motor, and a control cabinet. A transverse groove for the ribbed tube is provided in the center of the upper surface of the worktable. Supports are symmetrically arranged at both ends of the groove and connected to the worktable via the lifting mechanism. A lead screw rotating joint is connected between the two supports. The stepless motor is fixed to the outside of one support, and its output end is connected to one end of the lead screw for driving the lead screw. The finishing mold slides with the lead screw via a lead screw nut, and the shape of its lower end corresponds to the standard dimensions of the ribbed tube. The control cabinet is located on one side of the worktable and connected to the stepless motor and the lifting mechanism. This invention utilizes the horizontal reciprocating motion of the finishing mold under the control of the stepless motor to grind the ribbed shape, which not only improves grinding efficiency and reduces the labor intensity of workers but also ensures that the four ribbed tubes being ground have consistent shapes.
