Abstract

The invention discloses a small-diameter thin-walled tube bender which comprises a worktable, a tube bending die and a movable fixture block, wherein the tube bending die and the movable fixture block are arranged on the worktable; the movable fixture block is connected with one end of an adjusting bolt; the adjusting bolt is provided with a matching nut; a first axis pin is arranged in the tube bending die and movably connected with one end of an external roller clamp; the other end of the external roller clamp is connected with the adjusting screw; one end of the adjusting screw is connected with a handle; the other end of the adjusting screw is connected with one end of an internal roller clamp arranged in the external roller clamp; the adjusting screw is provided with a matching adjusting nut; and the other end of the internal roller clamp is respectively provided with two guide rollers which are matched with the tube bending die through a second axis pin. The invention has the advantages of simple structure and convenient operation, and can be used for bending small-diameter thin-walled box coiling tubes.

Description

technical field [0001] The invention relates to a pipe bending machine, in particular to a pipe bending machine for small-diameter thin-walled pipes. Background technique [0002] The structure of ordinary pipe bending machine generally includes: main drive, which is composed of bed, main cylinder sprocket and chain spindle; automatic corner device; support rack device; guiding and pressing mechanism and pipe mold; hydraulic system and oil pipe; electrical system ;The hydraulic system of the machine tool; mainly adopts winding pipe bending: the pipe bending mold is installed on the main shaft and the pipe is fixed on the clamping groove of the pipe bending mold through the clamp block, so that the two guide rollers are close to the pipe, when the pipe bending mold rotates , the pipe is wound around the circumference of the pipe bending die to obtain the required bending radius. Its disadvantage: it can only bend pipes with large diameter and relatively simple bending struct...
