Arc punching device and arc punching method at both ends of a circular tube

Abstract

The invention discloses an arc punching device for both ends of a circular tube and an arc punching method thereof. The arc punching device comprises an arc punching seat, a feeding rotating mechanism, and a pulling arc-punching mechanism; and a limiting sleeve is arranged in the arc punching seat, the feeding rotating mechanism comprises a base, a rotating cylinder, a connecting block, a roller,a spring, and a rotating cam, the pulling arc-punching mechanism comprises a cylinder body, an arc punching rod rotatably arranged in the arc punching seat, and a rotor and blades are arranged in thecylinder body. The arc punching method comprises the following steps that a pipe fitting is clamped and limited in a clamping mechanism, the rotating cam rotates, and one end of the pipe fitting is inserted into the limiting sleeve of the arc punching seat; the cylinder body is fed with oil, the rotor drives the arc punching rod to swing, and one side of one end of the pipe fitting is arc-punchedby cutters; the cylinder body is fed with oil in the backward direction, and the other side of one end of the pipe fitting is arc-punched by the cutters; and the feeding rotating mechanism exits, a rotating motor dives a worm to rotate, the worm drives a turbine ring to rotate by 90 degrees, the rotating cylinder drives the pipe fitting to overturn by 180 degrees, and the other end of the pipe fitting is arc-punched.

Description

technical field [0001] The invention relates to the field of arc-striking machining at ends of pipe fittings, in particular to an arc-striking device at both ends of a round pipe and an arc-striking method thereof. Background technique [0002] In the prior art, it is often designed to perform arc punching on both ends of the pipe, for example, in bicycle processing. In the existing arc punching 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 processed pipe is punched, 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...
