A small metal pipe bending device and its use method

Abstract

The invention provides a small-sized metal tube bending device and its use method, comprising a frame, on which a clamping part of a fixed end and a first mandrel are arranged, and rollers are arranged on the first mandrel; on the first mandrel The first gear is also rotatably arranged, the third clamping device is fixedly arranged on the first gear, the first rotating shaft is also arranged rotatably on the frame, the second gear and the ratchet are fixedly arranged on the first rotating shaft, the second gear and the first One gear meshes, and the ratchet is connected with a ratchet driving mechanism; the ratchet driving mechanism includes an active swing link, the middle part of which is hinged on the frame, and one end of the active swing link is hinged with a first link, and the first link is hinged with a driven link. One end of the driven swing rod is rotated and arranged on the first rotating shaft; the driven swing rod is provided with a driving pawl, and the frame is provided with a non-return pawl. The invention realizes the semi-mechanization of metal tube bending, can adapt to various working environments and satisfy various bending angles, and has simple overall structure, light weight, portability and low failure rate.

Description

technical field [0001] The invention belongs to the technical field of metal pipe bending, and in particular relates to a small metal pipe bending device and an application method thereof. Background technique [0002] With the rapid development of the communication industry in the past two decades, the application of cables has also developed at an astonishing speed. During the laying of existing cables, even if the existing underground construction generally uses cable trenches to protect the cables, for specific occasions, it is still necessary to install protective steel pipes outside the cables to provide protection against compression and corrosion. [0003] At present, in the cable laying process, due to factors such as process requirements or special construction site restrictions, the bending angle of standard-sized corner metal pipes is limited, which is difficult to meet the use requirements. The existing technology is to manually bend the spare metal pipe repeat...
