A Bending Die Device with Adjustable Bending Diameter Suitable for One Die and Multiple Tubes

Abstract

The invention discloses a bending die device with adjustable bending diameter which is suitable for one die and multiple pipes. Including control drive part, cone wheel mechanism and support bending die mechanism; control the curvature of the drive part to adjust the hydraulic cylinder to adjust the movement of the driven cone wheel in the cone wheel mechanism, and the bending die drive motor to adjust the active cone wheel and through the spline The rotation of the driven conical wheel connected with the driving conical wheel, the conical surface of the two conical wheels is uniformly opened with strip grooves, and the support sheet supporting the bending die mechanism is installed in the strip grooves of the two conical wheels and can During the movement, a plurality of support sheets form a support ring, and the elastic sheet fixing ring makes the support sheets cling to the two conical wheels. In the present invention, by adjusting the position of the driven conical wheel, the position of the supporting sheet is changed under the joint action of the thrust generated by the extrusion of the driving conical wheel and the driven conical wheel and the elastic force generated by the stretching of the elastic sheet fixing ring, and the The distance from the axis of the pipe to the axis of rotation of the bending die changes the radius of curvature to achieve continuous curvature.

Description

technical field [0001] The invention belongs to the field of bending and forming of pipe fittings, and in particular relates to a bending die device with adjustable bending diameter suitable for one die and multiple pipes. Background technique [0002] With the application of pipe fittings in various fields such as vehicles, aviation, ships, and pipelines, the use of pipe bends in various industrial fields has become more and more important, and automatic pipe bending technology has also continued to develop. At present, most of the mechanism pipe bending machines and CNC pipe bending equipment used in production are based on the rotary stretching pipe bending method. The bending of the pipe is directly completed by the special mold under the action of rotary stretching. The main components of the tube forming method directly determine the radius of curvature of the bend. [0003] Bend pipes with different radii of curvature in different bending sections of the same pipe or...
