Single-oscillating-arm leftward and rightward co-bending type numerical control pipe bending machine

Abstract

The invention relates to a single-oscillating-arm leftward and rightward co-bending type numerical control pipe bending machine and belongs to the technical field of pipe processing. The numerical control pipe bending machine comprises a machine frame, a control unit, a feeding trolley, a machine head, a mold guide unit and a switching unit, wherein the feeding trolley, the machine head, the mold guide unit and the switching unit are installed on the machine frame and controlled by the control unit; the machine head comprises a clamping mold, a round mold, an oscillating arm and a pipe bending motor, the oscillating arm shares the same drive spindle with the round mold, and the pipe bending motor is used for driving the round mold and the oscillating arm to rotate to bend a pipe and to rotate at the leftward pipe bending position or the rightward pipe bending position in a switching mode; and the switching unit is controlled by the control unit to drive the machine head to move transversely or vertically perpendicular to the axial direction of the pipe to be bent relative to the machine frame so that the machine head can be driven to switch between the leftward pipe bending position and the rightward pipe bending position. By means of the single-oscillating-arm leftward and rightward co-bending type numerical control pipe bending machine, leftward and rightward co-bending can be achieved based on the single oscillating arm, the pipe bending quality can be effectively improved, and the numerical control pipe bending machine can be widely applied to the fields of air conditioners, aviation and the like.

Description

technical field

[0001] The invention relates to pipe material processing equipment, in particular to a single swing arm left and right co-bending type numerically controlled pipe bender. Background technique

[0002] CNC pipe bending machines are widely used in air conditioners, automobiles, ships, aerospace and other industrial fields. The circular die used to control the radius of the pipe bending, the swing arm, the clamping die installed on the swing arm and used to clamp the pipe together with the circular die, and the circular die and the swing arm are driven to rotate around the rotation axis of the driving spindle to bend the pipe Tube bending motor for tube action. According to the different bending directions, it can be divided into left-bend type pipe bender, right-bend type pipe bender and left-right bend type pipe bender.

[0003] The patent document with the publication number CN101817038A discloses a bending mechanism for building a left and right co-bending...
