Bending device and U-shaped pipe machining equipment

Abstract

The invention provides a bending device and U-shaped pipe machining equipment. The bending device comprises a bending mechanism and a contact pattern mechanism, wherein the bending mechanism comprisesclamping portions, and the clamping portions comprise clamping spaces for containing pipe parts and first position-limiting grooves, are rotatably arranged and are provided with feeding positions andbending positions; the contact pattern mechanism comprises position-limiting portions, and the position-limiting portions are provided with second position-limiting grooves for containing the pipe parts, are movably arranged both in a first direction and a second direction and are provided with first position-limiting positions, second position-limiting positions and third position-limiting positions; and in the process of the clamping portions rotating from the feeding positions to the bending positions, the position-limiting portions move from the first position-limiting positions to the second position-limiting positions in the second direction and move from the second position-limiting positions to the third position-limiting positions in the first direction to make the first position-limiting grooves and the second position-limiting grooves be butted and clamp the pipe parts. By means of the bending device and the U-shaped pipe machining equipment, the problem of the poor qualityof U-shaped pipes produced and obtained by a bending device in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a bending device and U-shaped pipe processing equipment. Background technique [0002] U-shaped tubes are widely used in air conditioners. Correspondingly, small air conditioners need to use small U-shaped tubes, and the smaller U-shaped tubes are difficult to process. [0003] The bending device of the U-shaped pipe processing equipment in the prior art adopts a fixed bending method to bend the pipe fittings. During the bending process, the pipe fittings and the profiling mechanism will move relative to each other, causing the U-shaped pipes to bend during the bending process. Defects such as wrinkling, flattening, bagging or scratches will appear at the bend, and the quality of the produced product will be poor. Contents of the invention [0004] The main purpose of the present invention is to provide a bending device and U-shaped tube processing equipment to...
