A kind of arc punching equipment and arc punching method at both ends of circular tube

Abstract

The invention discloses a device and a method for punching arcs on two ends of a circular pipe. The device comprises an arc punching seat, a feeding and rotating mechanism and a pulling and arc punching mechanism. A limiting sleeve is arranged in the arc punching seat; the feeding and rotating mechanism comprises a base, a rotary cylinder, a connecting block, a guiding pillar, a spring, a connecting rod, a drive gear and two driven gears; the pulling and arc punching mechanism comprises a rotary plate, a slide block, a drive rod, and an arc punching rod rotatably arranged in the arc punching seat; the rotary plate drives the drive rod to swing; and the drive rod drives the arc punching rod to swing. The arc punching method comprises the following steps: a pipe is clamped and limited in a clamping mechanism, the drive gear rotates, one fan-shaped gear drives one end of the pipe to be inserted into the limiting sleeve in the arc punching seat, the rotary plate rotates, the drive rod drives the arc punching rod to swing back and forth, a cutter carries out arc punching processing on two sides of one end of the pipe, the other fan-shaped gear drives the pipe to retreat, a rotary motordrives a worm to rotate, the worm drives a worm wheel to rotate at 90 degrees, the rotary cylinder drives the pipe to turn over at 180 degrees, and the other end of the pipe is subjected to arc punching processing.

Description

technical field [0001] The invention relates to the field of arc-striking machining at the end 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 w...
