A kind of welding method of glass tube and metal tube

Abstract

The invention discloses a welding method for glass tubes and metal tubes. The welding method includes the following steps that a glass tube conveying device conveys the glass tubes into an inner cavity of a first clamping part, and a first chuck clamps the glass tubes; a metal tube conveying device conveys the metal tubes onto a second chuck of a second clamping part, and the second chuck clamps the metal tubes; a first clamping disk drives the glass tubes to rotate, and a welding rod on a welding holder is rotated so that a welding head can heat the side walls of the ends of the glass tubes;a U-shaped cavity formed between squeezing stop rods of a squeezing part is arranged on the side walls of the ends of the glass tubes in a sleeving mode, a squeezing base squeezes the ends of the glass tubes so that the ends of the glass tubes can extend to the squeezing stop rods, and the tube wall thicknesses are increased; the second clamping part moves towards the first clamping part, the endsof the metal tubes are inserted into the ends of the glass tubes, and the welding head is used for heating the side walls of the glass tubes so that the metal tubes and the glass tubes can be weldedtogether; and the first chuck and the second chuck are loosened, and the welded glass tubes are stored for standby application. The welding method for the glass tubes and the metal tubes has the advantages that the ends of the glass tubes and the ends of the metal tubes can be welded, welding efficiency is high and the welding effect is good.

Description

technical field [0001] The invention relates to the technical field of glass tube production, in particular to a welding method for a glass tube and a metal tube. Background technique [0002] An existing Chinese invention patent with the patent number CN200710154507.2 titled "Metallic Glass Composite Heat Conductor Tube and Its Manufacturing Method" discloses a metal glass composite heat conduction tube arranged in an evacuated tube solar collector and a manufacturing method thereof. The metal-glass composite heat-conducting tube is formed by pouring metal tubes and glass tubes. The middle part of the metal tube is a mesh section, which is in a mesh structure. The glass tube is coated on the metal tube and exposes the two ends of the metal tube. , and includes a mesh section covered with a metal tube, one end of the metal tube is connected to the metal heat conducting tube of the vacuum tube solar heat collector, and a glass end cover is provided at the interface between th...

AI Technical Summary

Problems solved by technology

However, this method cannot realize the welding between the end of the glass tube and the end of the metal tube, and the welding efficiency is low, and the welding effect is not ideal, so this method needs further improvement
