Abstract
The utility model relates to a mixed gas multi-nozzle welding device, which is mainly composed of combustible gas (1), combustion-supporting gas A and B, a welding gun (6) with welding nozzles (5) and a gas proportioning device (7) arranged between the combustion-supporting gas A and B and the welding gun. The combustion-supporting gas A and B are adjusted and proportioned by a gas proportional adjusting button on the gas proportioning device. After the combustion-supporting gas A and B are mixed, the combustion-supporting gas A and B are input the welding gun to be mixed with the combustible gas, and the weld is completed on the welding nozzles. The utility model carries out reasonable structural design for the existing multi-nozzle welding device according to the utility model and new gas source proportioning solutions. The utility model has simple operation and stable weldability, improves the qualified rate of welding products, reduces production cost, and is suitable for welding and processing metal pipe fittings in mechanical manufacture industries, light industries, etc.
Description
The utility model relates to the architecture advances of metal tube welder.
In industrial aspect, the gas welding is to realize electroplating equipment wielding machineization, one of main direction of automation, with the bicycle trade is example, the salt bath furnace immersed solder technology that tradition falls behind in vehicle frame welding is big because of difficult quality guarantee such as vehicle frame distortion and power consumption, seriously polluted, shortcoming such as labor strength the is big oil gas welding of speaking out of turn that is liquefied gradually replaces.The liquefied petroleum gas that generally adopts is spoken out of turn welding because the welding equipment complex structure at present, fault is more, it is easy to increase maintenance cost, influence ordinary production and product quality, the price of liquefied gas is higher simultaneously, restricted of the application of gas solder technology, the phenomenon that salt bath furnace and liquefied gas welding occur and deposit in medium and small cycle frame manufacturing enterprise at bicycle trade.
The purpose of this utility model provides and a kind ofly can improve welding quality, the novel welder that reduces production costs.
The utility model is the gaseous mixture welder, mainly by fuel gas (1) and tracheae (2), combustion-supporting gas A and tracheae (3), combustion-supporting gas B and tracheae (4), the welding gun (6) of tape welding mouth (5) places gas mixing ratio device (7) and tracheae formations such as (8) between combustion-supporting gas A, B and the welding gun.
The following source of the gas of the preferential employing of the utility model; Fuel gas (1) is an acetylene, combustion-supporting gas A is an oxygen, combustion-supporting gas B is a compressed air, combustion-supporting gas A and B adjust proportioning by the gas ratio adjusting knob on the gas mixing ratio device, mix the back and be transported to welding gun by tracheae (8), mix with the fuel gas that is flowed into welding gun by tracheae (2), igniting is carried out welding operation behind the back.
The utility model is according to new source of the gas mix proportion scheme, welder has been carried out reasonable structural design, simple to operate, overcome the liquefied petroleum gas defectives such as welding cost height of speaking out of turn,, improved the welding product qualification rate stablizing solderability, effect has preferably reduced production costs, through the practical application in the bicycle rack welding, to compare with the liquefied petroleum gas welding, welding cost descends more than 80%.The utility model is applicable to machine-building, the welding and the processing of industry metal tubes such as light industry.
Accompanying drawing has provided structural representation of the present utility model.
Below in conjunction with embodiment the utility model is further described.
Fuel gas acetylene (1) is connected with welding gun (6) through tracheae (2), and oxygen A and compressed air B are respectively through tracheae (3), and (4) are connected with gas mixing ratio device (7), and ring-type is provided with 6-10 tips on the welding gun.During use,, after mixing, the gas ratio adjusting knob (9) on gas mixing ratio device adjustment, can on the bull tip, weld after the igniting by tracheae (8) input welding gun with oxygen and compressed air.
Claims (3)
1, a kind of gaseous mixture welder, comprise fuel gas (1) and tracheae (2) combustion-supporting gas A and tracheae (3), combustion-supporting gas B and tracheae (4), the welding gun (6) of tape welding mouth (5) is characterized in that also comprising the gas mixing ratio device (7) and the tracheae (8) that place between combustion-supporting gas A, B and the welding gun.
2, by the described gaseous mixture welder of claim (1), it is characterized in that described fuel gas is an acetylene, combustion-supporting gas A is an oxygen, and B is a compressed air.
3, by claim (1) or 2 described gaseous mixture welders, it is characterized in that described gas mixing ratio device is provided with gas ratio adjusting knob (9).
