Automatic arc forming equipment for pipe fittings and arc forming method thereof

Abstract

The invention discloses automatic arc-forming equipment for a tube and an arc-forming method of the automatic arc-forming equipment. The equipment comprises a fixed ring, wherein a plurality of arc-forming mechanisms are peripherally arranged on the outer part of the fixed ring; an arc-forming grinding head is rotatably arranged inside the fixed ring; and each arc-forming mechanism comprises a slide steering assembly, a transport assembly and an unloading assembly. The arc-forming method comprises the following steps of: inserting one end of a tube to be subjected to arc-forming into a limiting hole in the fixed ring; rotating the arc-forming grinding head, slowly extending out a slide cylinder, and performing arc-forming processing on one end of the tube through an arc surface grinding layer on the arc-forming grinding head; moving the tube out of the fixed ring, rotating a rotary cylinder by 180 degrees, inserting one end of the tube into a locking sleeve of a clamping hole, and rotating the rotary cylinder by 90 degrees; extending out the slide cylinder, pushing the other end of the tube into the fixed ring, and performing arc-forming processing on the other end of the tube; retracting the slide cylinder, re-moving a clamping part to one end of the tube, moving the tube to an inlet of an unloading channel, electrifying a second electromagnet, and dropping the tube into an unloading box through an unloading channel.

Description

technical field [0001] The invention relates to the field of arc-forming machining at the ends of pipe fittings, in particular to an automatic arc-forming equipment 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 ex...
