Automatic pipe arc-forming device and arc-forming method thereof

Abstract

The invention discloses an automatic pipe arc-forming device and an arc-forming method of the automatic pipe arc-forming device. The automatic pipe arc-forming device comprises an arc-forming seat, afeeding rotating mechanism and a shifting arc-forming mechanism. A limiting sleeve is arranged in the arc-forming seat. The feeding rotating mechanism comprises a base, a rotating cylinder, a rack, asector-shaped plate, a connecting rod and a rotating drum. The shifting arc-forming mechanism comprises a driving piece, triggers arranged on the two sides of the driving piece, an arc-forming rod rotationally arranged in the arc-forming seat and springs. The arc-forming method comprises the following steps that a pipe is clamped and limited in the clamping mechanism, the rotating drum rotates, one end of the pipe is inserted into the limiting sleeve in the arc-forming seat, a shifting disc drives the arc-forming rod to swing, one side of one end of the pipe is subjected to arc-forming processing by a cutter, the shifting disc rotates reversely, the other side of one end of the pipe is subjected to arc-forming processing by the cutter, the rotating drum drives the feeding rotating mechanism to retreat, a rotating motor drives a worm to rotate, the worm drives a turbine ring to rotate by 90 degrees, the rotating cylinder drives the pipe to turn over by 180 degrees, and the other end ofthe pipe is subjected to arc-forming processing

Description

technical field [0001] The invention relates to the field of arc forming machining at the end of pipe fittings, in particular to an automatic arc forming device for pipe fittings and an arc forming method thereof. Background technique [0002] In the prior art, it is often designed to process the two ends of the pipe into an arc, for example, in bicycle processing. In the existing arc forming process, the processing is generally carried out manually, and the processing is carried out by the hand of the worker, and the processing efficiency is low. At the same time, after the processing of one end of the pipe is completed, before the other end of the pipe is processed, the pipe needs to be turned over and at the same time A 90-degree rotation is required. If the 90-degree rotation is performed manually, the arcs at both ends of the pipe cannot be guaranteed to be orthogonal, resulting in poor machining accuracy. [0003] For this reason, the Chinese invention with the existi...
