Summary of the invention
The utility model is to exist when solving the welding that existing welding equipment has oxide layer, hydrogen embrittlement, welding stress not enough the proposition such as to concentrate, and aims to provide and has the vacuum welding function and can solve that welding stress is concentrated and the absorption type vacuum welding that improves the problems such as weld strength is equipped.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Absorption type vacuum welding equipment, comprise vacuum welding cover, elastic packing flexible glue, welder, is provided with the elastic packing flexible glue between vacuum welding cover and welded piece, and welder is positioned at vacuum welding cover inside, and the thickness of vacuum welding cover is more than or equal to 1mm.By being used in combination of vacuum welding cover and elastic packing flexible glue, make welder implement welding under the state of vacuum or nearly vacuum, thereby the appearance of oxide layer and hydrogen embrittlement while having avoided welding, the quality of welding is improved, makes the overall performance after during welding for steel structure obtain maximum performance.And after having welded, as long as the Mobile vacuum welding enclosure just can be realized continuous welding.
Especially vacuum welding cover, vavuum pump and vacuum storage tank three are used alternatingly each other, have both realized condition of high vacuum degree, have also realized the raising of production efficiency.
As preferably, the vacuum welding cover separates with the elastic packing flexible glue, and the shape of elastic packing flexible glue is coincide with vacuum welding shroud rim and welded piece surface respectively.The elastic packing flexible glue is pressed in the welded piece surface by the vacuum welding cover, has prevented that outside air from entering vacuum welding cover inside, avoided the appearance of gas leak phenomenon.
As preferably, the elastic packing flexible glue is assemblied in the edge of vacuum welding cover, and the shape of elastic packing flexible glue is coincide with vacuum welding shroud rim and welded piece surface respectively.Elastic packing flexible glue and vacuum welding cover link into an integrated entity, and have facilitated being used in combination of elastic packing flexible glue and vacuum welding cover.
As preferably, the shape of the edge shape of vacuum welding cover and welded piece contact surface is coincide.Guaranteed the tightness of vacuum welding cover and welded piece contact position.The vacuum welding cover is connected with vavuum pump, and the vacuum welding cover is connected with vacuum storage tank, and vavuum pump is connected with vacuum storage tank.
Vacuum welding cover, vavuum pump are connected each other with the vacuum storage tank three.After the vacuum welding cover is in place, utilize jumbo vacuum storage tank to be pumped at short notice basic vacuum than air in the vacuum welding cover of low capacity, close vacuum storage tank, open vavuum pump and further the residual air in the vacuum welding cover is evacuated to vacuum or nearly vacuum, when the vacuum welding cover changes next welding bead, vavuum pump is evacuated to vacuum or nearly vacuum by the residual air in vacuum storage tank, and the three is used alternatingly each other, reaches best efficiency and vacuum state.
As preferably, the orbit of welder is fixed in the welded piece surface and is positioned at vacuum welding cover inside, or welder be take the welded piece surface as orbit.The track of welder by being fixed on surface of the work be at vacuum welding cover internal operation, thereby implement welding job.Welder can also be directly using surface of the work as track, and in the surface of the work operation, thereby implement welding job.
As preferably, the orbit of welder is fixed in vacuum welding cover inside, or welder directly to take the inner surface of vacuum welding cover be orbit.The track of welder by being fixed on vacuum welding cover inside be at vacuum welding cover internal operation, thereby implement welding job.Welder can also be directly using surface of the work as track, and in the surface of the work operation, thereby implement welding job.
As preferably, the vacuum welding cover is transparent material; Surface on welded piece except vacuum welding cover position is provided with insulation material.By laying insulation material, make workpiece when welding in temperature constant state.When welding, can directly see inner welding fact by the vacuum welding cover of transparent material, facilitated the timely control to welding process.
According to the technical solution of the utility model, absorption type vacuum welding equipment carries out whole welding process under the state of vacuum or nearly vacuum, no longer needs the protection of inert gas while making to weld.When utilizing vavuum pump to be bled to vacuum welding cover inside, not only extracted other of vacuum welding cover inside out, also extract the impurity of vacuum welding cover inside out, thereby avoided the appearance of oxide layer.Simultaneously, owing to substantially there not being air pressure in the vacuum welding cover, the boiling point in molten bath is reduced, the activity in liquid molten bath increases, and is conducive to fusing and the combination of welding wire and mother metal.In addition, also solved due to problems such as the concentrated distortion caused of welding stress, hydrogen embrittlement, fractures.By laying insulation material, also make whole welding process carry out under the state of constant temperature, improved welding quality.The technical program makes welding procedure obtain revolutionary progress, greatly must improve the scope of application of welding procedure, the welding of especially applicable high-strength material and large shape.
