Abstract
The utility model relates to a device used for welding and cutting metal steel. The aims of the utility model are to solve the problems that existing device which uses liquefied gas can only be used for cutting, and the weld can not carry out because the fire can not be flamed. The device is composed of a welding tip body, and a welding tip jacket, wherein, the welding tip body is provided with a plurality of radial vent holes which are vertically positioned with axial vent holes, and the outer cone body of the vent hole is provided with a plurality of vent grooves; the welding tip jacket and the welding tip body are combined together by internal and external threads. After being connected, the radial vent holes of the welding tip body and the vent grooves are contained by the welding tip jacket. The device solves the problems that existing liquefied gas can only be used for cutting metal but not welding the metal. The utility model has the advantages of good welding properties, low cost of the fuel, and low welding cost.
Description
The utility model relates to weldering, cuts the apparatus of metal steel, especially makes fuel with liquefied gas and can be installed on the welding gun for a kind of, and device is chewed in a kind of novel weldering that can weld.
Traditional welding is to adopt acetylene gas (C
2H
2) be fuel, consuming electric power when producing calcium carbide, valency height, contaminated environment also when using.Present useful liquefied gas is made fuel, and fuel price is cheap, and the cutting steel product quality is good, meets difficulty but weld, and promptly chews gas output with former weldering and misfires, and people claim: it is cheap to make fuel price with liquefied gas, but can only cut, and can not weld.Said liquefied gas is the compound of carbon 3 gas carbons 4 gas, and carbon 3 gas are propylene (C
3H
6), propane (C
3HC
8), carbon 4 gas are butylene (C
4H
8), butane (C
4H
10).This liquefied gas raw material is easy to get, inexpensive.
The purpose of this utility model provides a kind of liquefied gas that can adapt to and chews device do the novel weldering that fuel welds.
Formation of the present utility model:
This novel weldering is chewed device and is chewed body and weldering by weldering and chew cover two parts and constitute, and its weldering is chewed body and is provided with and the supporting internal thread of welding gun bar external screw thread, chews on the body in weldering to be provided with: with axial bore perpendicular several radially breeder tubes are arranged; Outside at its awl end is provided with the groove that several can be ventilated along circumference, but bottom land and its axial bore should keep certain wall thickness; Chew in weldering to be provided with on the external diameter of body with welding and chew the external screw thread that the cover internal thread matches.The front end that cover is chewed in weldering is the cover of external taper in a kind of being provided with, the internal taper of its cover should and weldering chew between the external taper that contains several air channels of body front end to movingly, weld and chew in cover also chews weldering several on body radially breeder tube is included in.It is exactly a part of liquefied gas as fuel in the axial hole to be chewed in the body in weldering be diverted to its several passage radially that device is chewed in this novel weldering.In several air channels, then with its axial hole in liquefied gas get together mutually, can guarantee that the welding time point catches fire and carries out normal welding job.
The utility model is described further middle in conjunction with the accompanying drawings embodiment:
Fig. 1 makes the overall construction drawing that device is chewed in the novel weldering of fuel for adapting to liquefied gas,
Fig. 2 chews body structure figure for the weldering in Fig. 1 device,
Fig. 3 chews the noose composition for the weldering in Fig. 1 device.
In the diagram zero, parts and the explanation of position sequence number thereof:
1, body is chewed in weldering, the radially breeder tube on the body is chewed in 1-1, weldering, and the air channel on the body is chewed in 1-2, weldering, and the external screw thread on the body is chewed in 1-3, weldering, the screw thread on the body is chewed in 1-4, weldering, axial passage on the body is chewed in 1-5, weldering, and the external diameter of body upper vent hole end is chewed in 1-6, weldering, and 2, weldering chews cover, the internal thread that puts is chewed in 2-1, weldering, the internal diameter that puts the ventilation stomidium is chewed in 2-2, weldering, and four directions or six sides that put are chewed in 2-3, weldering, and 3, weldering chews cover to be installed to the axial distance that welds after chewing on the body poor.
This liquefied gas that can adapt to is done the novel weldering of fuel and is chewed device, by weldering chew body [1], the weldering that contains inside and outside tapering chews cover [2] and constitutes.Chew on the body [1] in weldering and to be provided with: with perpendicular passage [1-1], several air channels [1-2], external screw thread [1-3], the internal thread [1～4] of axial passage [1-5], axially the external diameter of ventilation end is [1-6]; Chew internal diameter [2-2], four directions or six sides [2-3] that are provided with internal thread [2-1], ventilation stomidium on the cover [2] in weldering; Weldering chew the internal thread [2-1] that puts by weldering chew on the body external screw thread [1-3] weldering chew body [1], weldering is chewed cover [2] and is linked together, connect the back weldering and chew to be enclosed within to weld to chew certain axial distance poor [3] should be arranged on the body.
On state several radially passage [1-1] can be the 1-5 hole, several air channels [1-2] can be the 3-12 groove, the aperture that the axial passage [1-5] on the body is chewed in weldering can be 0.7-0.8mm, and body is chewed in weldering, weldering is chewed the axial difference of overlapping after connecting and be can be 0.3 ± 0.1mm apart from [3].
The internal thread [1-4] that weldering is chewed on the body [1] can be connected with the external screw thread on the welding gun bar.
Good effect of the present utility model:
1, makes fuel with liquefied gas, adopt this Novel welding to chew device, solved on the current social and welded The workman can only cut, can not weld the problem of (misfiring).
2, the apparatus structure manufacturing reasonable in design, easy, stable work in work, Welder are chewed in this weldering The people operates use easily.
3, changing acetylene is that liquefied gas cheap and easy to get welds as fuel as fuel, and welding cost is low.
