Abstract
The invention relates to the field of welding machines, and in particular relates to a protection cover used for gas shield welding. The protection cover comprises a connection pipe and a gas outlet pipe. The connection pipe is connected with a welding nozzle, the inner diameter of the gas outlet pipe is larger than that of the connection pipe, and the gas outlet pipe is connected with the connection pipe by a connection sloping surface. Red copper is adopted by the protection cover as a manufacture material so that the manufacture process is simpler and more practicable than ceramics and the protection cover is not easily damaged in work. A protection gas plays a protective effect in a wide range and the welding quality is improved due to that the gas outlet pipe with a larger diameter and a gas guide taper cylinder are adopted.
Description
Technical field
The present invention relates to the welding machine field, especially protect weldering and use protective cover for a kind of gas.
Background technology
Gas-shielded welder is when weld job; Need airborne oxygen be completely cut off with pad with protective gas around the welding tip and come; Take away the heat of pad on the one hand; Make it cooling as early as possible after welding, prevent that on the other hand airborne oxygen from contacting the pad oxidation with the pad of high temperature, cause pad intensity to reduce.Protective gas has CO2, CO2 and argon gas mist, CO2 and helium mix gas etc.Existing gas is protected weldering and use protective cover, and its main body is a straight-tube shape, be unfavorable for forming effective protective gas wall around the pad, and employing is ceramic material the frangible environment needs that can not satisfy the field Welding operation.
Summary of the invention
The object of the invention is to address the above problem, and provides a kind of gas to protect weldering and has used protective cover, is specifically realized by following technical scheme.
A kind of gas is protected weldering and is used protective cover, is connected with the tip of welding machine, and this protective cover comprises tube connector and escape pipe, and said tube connector is connected with said tip, and said escape pipe internal diameter connects domatic connection greater than tube connector and both through one.
Said gas is protected weldering and is used protective cover, and further design is that the end of said tube connector is provided with the connection draw-in groove.
Said gas is protected weldering and is used protective cover, and further design is, this gas is protected weldering and adopted red copper to process with protective cover.
Said gas is protected weldering and is used protective cover, and further design is, the end edge of said escape pipe is connected with an outside gas guide cone tube that distributes.
Said gas is protected weldering and is used protective cover, and further design is that said gas guide cone tube is provided with a plurality of outgassing grooves.
The present invention has adopted red copper as manufacturing materials, makes manufacture craft more simple and be difficult in operation damaged than pottery; Owing to adopted bigger escape pipe of diameter and gas guide cone tube, make protective gas in a big way, produce protective effect, improved welding quality.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the present invention is further specified.
This gas is protected weldering and is used protective cover; Be connected with the tip of welding machine; Comprise tube connector 1 and escape pipe 2, tube connector 1 connects with the draw-in groove 11 that is connected of tip (not drawing among the figure) through the end setting of tube connector 1, and escape pipe 2 internal diameters connect through connecting domatic 3 greater than tube connector 1 and both.Gas is protected weldering and is adopted red copper to process with protective cover.The end edge of escape pipe 2 is connected with an outside gas guide cone tube 4 that distributes.The edge of gas guide cone tube 4 evenly is provided with six (among the figure visible three) outgassing grooves 41.
The gas shiled cover of existing automatic welder(welding machine) uses pottery as manufacturing materials usually; It is raw material that the present invention adopts red copper; Red copper is as the ceramic special construction that is processed into various adaptation operation needs more easily of ductility preferred metal; And, guaranteed welding quality thereby make protection domain enlarge through thicker outlet pipe gas guide cone tube is set.
Claims (5)
