Description
Technical field
The utility model belongs to welding field, specifically, relates in particular to a kind of welding gun for tube sheet spot welding.
Background technology
As everyone knows, welding is a kind of utilization manufacturing process widely, and existing main welding manner has gas shielded arc welding and spot welding etc., and welding carrys out corresponding selection welding manner according to the characteristic of welding object often.Welding for thin-wall pipes and thin plate; the general gas shielded arc welding that adopts welds at present, but this welding manner not only very easily causes the serious weld defects such as burn-through, dry joint, and energy welder's labour skill require high; thereby cause human cost high, production efficiency is low.
In addition, also someone thought employing spot welding mode by thin-wall pipes together with plate sheet welding.But the opposite face of the upper and lower electrode of welding gun that existing spot welding mode adopts is plane, through test weld proof, cannot meet welding requirements.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of welding gun for tube sheet spot welding, with mash welder by this welding gun is housed by thin-wall pipes together with plate sheet welding.
The technical solution of the utility model is as follows: a kind of welding gun for tube sheet spot welding, on weldering body (1), top electrode (2) and bottom electrode (3) are housed, wherein top electrode (2) and bottom electrode (3) can move in opposite directions, and bottom electrode (3) is cylinder, its end face is plane, it is characterized in that: described top electrode (2) is cylinder, the bottom surface of this top electrode is the arc surface of depression, corresponding central angle≤180 ° of this arc surface.
The utility model, on the basis of traditional structure, is adjusted into cylinder by described top electrode (2), and the bottom surface of this top electrode is the arc surface of depression, corresponding central angle≤180 ° of this arc surface.
In manufacturing the process of top electrode (2), the external diameter of described top electrode (2)≤welded thin-wall pipes external diameter, and arc surface radius=welded thin-wall pipes external diameter/2 of top electrode (2) bottom surface, and the corresponding central angle size of this arc surface is determined according to the wall thickness of welded thin-wall pipes; When the wall thickness of welded thin-wall pipes is thinner, the corresponding central angle of described arc surface is larger, and when the wall thickness of welded thin-wall pipes is thicker, the corresponding central angle of described arc surface is less.
When welded thin-wall pipes bears pressure during the resistance of the resistance≤bottom electrode of indeformable and thin-wall pipes; be equipped with the electric welding machine of this welding gun can be very securely by thin-wall pipes together with plate sheet welding; thereby overcome preferably the defect that traditional gas shielded arc welding mode is welded thin-wall pipes and thin plate; and just solved large problem by little change; there is good technology and economic worth, be suitable for extensively promoting the use.
In this case, described top electrode (2) and bottom electrode (3) are copper electrode.
As a kind of embodiment, described bottom electrode (3) is fixing, and top electrode (2) is fixed with the piston rod of cylinder (4), and this cylinder is vertically fixed on described weldering body (1).
As a kind of embodiment, described top electrode (2) is fixing, and bottom electrode (3) is fixed with the piston rod of cylinder (4), and this cylinder is vertically fixed on described weldering body (1).
As another embodiment, described top electrode (2) and bottom electrode (3) are fixed with the piston rod of a cylinder (4), and these two cylinders are all vertically fixed on described weldering body (1).
Beneficial effect: when welded thin-wall pipes bears pressure during the resistance of the resistance≤bottom electrode of indeformable and thin-wall pipes; be equipped with the electric welding machine of this welding gun can be very securely by thin-wall pipes together with plate sheet welding; thereby overcome preferably the defect that traditional gas shielded arc welding mode is welded thin-wall pipes and thin plate; and just solved large problem by little change; there is good technology and economic worth, be suitable for extensively promoting the use.
