Description
Technical field
The utility model belongs to heat exchange coil high frequency tube-making process technical field, in particular to a kind of to exchange heat for stainless steel
The novel welding roller arrangement of coil pipe high-frequency welding.
Background technique
During high frequency pipe mill continuously welds stainless-steel pipe, due to a certain amount of chromium of stainless steel content itself,
Therefore it is contacted in the welding process with oxygen and easily forms higher melting-point chromium oxide, this has the welding quality of stainless-steel pipe
Strong influence compares carbon steel ratio-frequency welding, increases biggish difficulty, therefore during high frequency rolls stainless-steel pipe
A possibility that oxygen around weld seam should be reduced as far as possible, reduce the oxide formation of chromium.Conventional weldering roller system is without sealing
Box, steel-pipe welding are completely exposed outside in the process, cannot be completely by oxygen even if effect is also bad using protective gas
Air bound from.
Utility model content
The purpose of the utility model is to overcome the above problem, provide a kind of for stainless steel heat exchange coil high-frequency welding
Novel welding roller arrangement.
The technical solution that the utility model is taken to achieve the above object are as follows: one kind is used for stainless steel heat exchange coil high frequency
The novel welding roller arrangement of welding, it is characterised in that: the weldering roller arrangement includes weldering roller regulating mechanism and welding protective gas sealing
Mechanism；The weldering roller regulating mechanism includes the weldering roller regulating device for welding roller and connection weldering roller, and weldering roller regulating device, which is equipped with, to be adjusted
Weld the knob of roller position and extruding force；The welding protective gas sealing mechanism includes that protective gas seal box and protective gas connect
Pipe, protective gas seal box front connection weldering roller, tube rolling entrance, the surface of protective gas seal box are reserved in front and back end relative position
Equipped with protective gas air inlet and induction coil interface, it is correspondingly connected with protective gas adapter tube and induction coil, the two of induction coil
A straight-arm is by two cover board grip seals, securing member on cover board.
It is respectively connected with two sets of transmitting lead screws, i.e., one positive screw rod and an anti-screw rod below the weldering roller, welds the master of roller
Axial filament thick stick is connected with positive and negative lead screw, transmitting rotation step-length, knob with weld roller main shaft lead screw connect, knob during rotation,
Two weldering rollers can be mutually close to or separate, and the extruding force of weldering roller is controlled with this.
The protective gas seal box uses nylon material resistant to high temperature.
The protective gas includes nitrogen or argon gas.
The utility model use nylon material resistant to high temperature, according to compression roller size, adjust surplus, induction coil size and
Position Design goes out a set of compact-sized, good airproof performance protective gas seal box, and surface has protective gas air inlet, protects gas
Body can use nitrogen, and the nitrogen of certain flow is enriched in seal box, the air around weld seam is on the one hand supplanted, another
Aspect can also play the role of cooling with butt welding roller surface.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, welding roller；2, roller regulating device is welded；3, protective gas seal box；4, protective gas is taken over；5, the line of induction
Circle.
Specific embodiment
The present invention will be further described with specific embodiment with reference to the accompanying drawing, but the utility model is not limited to have
Body embodiment.
