During avoiding tubulation from welding, stainless steel side weld is uneven and situations such as fusing uneven, burn-through, weld seam stays easily occurs,
Improve the performance of compound straight-seam pipes in stainless steel composite material.
The utility model is realized by following technical proposal：A kind of straight-seam pipes tubulation welds water cooling cushion device, including band
There is the bracket of connecting rod, be arranged on the support wheel of bracket base and be arranged on the pad of pallet top, the mats inside is set
There is water-cooling channel.
The pad upper end is boss, lower end is chock, and the chock is placed in the inside groove opened up on bracket, makes pad upper end
Boss upper surface be close to tube blank inner wall.
Spring is provided with positioned at chock bottom in the bracket inside groove, the boss upper table of pad upper end is made by the effect of spring
It is close to tube blank inner wall in face.
The support wheel is arranged in pairs in bracket base, and support wheel plays a part of supporting water cooling cushion device, and can be
Inside pipe wall rolls, and reduces the friction with inside pipe wall, protects cladding stainless steel.
The water-cooling channel include be located at pad upper end boss in horizontal channel and connected with horizontal channel it is vertical
Drainage channel.
The horizontal channel outer end sets water inlet, and water inlet passes through pipeline and water source（Cistern or water tower）It is connected.
Inside groove bottom on the bracket is provided with through hole, for the water for entering inside groove to be discharged.
The material of the pad is copper.
The connecting rod is connected with the unit outside pipe, to prevent the cold cushion device of water from being moved with pipe, serves as a contrast water cooling
The position of cushion device is remained at immediately below welding gun.
Straight-seam pipes tubulation welding water cooling cushion device is arranged on inside pipe, immediately below welding gun, when tubulation welds, molten bath
Liquid metal can not continue flow down because pad is close to inner tubal wall.Liquid state of molten pool metal is set to be filled with stainless steel side mother metal
Divide fusion, reduce the weld defects such as slag inclusion, solder skip, rosin joint and occur.Ensure stainless steel side weld quality and welding uniformity and steady
It is qualitative.When tubulation welds, water is flowed into from water inlet and padded, and is flowed out by delivery port.Pad is taken away to absorb when tubulation welds
Partial heat so that pad be in low-temperature condition all the time, ensures that pad will not ensure that tubulation welds because working long hours and scaling loss
Connect and be smoothed out for a long time.
The advantages of the utility model and effect：Water cooling cushion device is welded using above-mentioned straight-seam pipes tubulation, effectively reduced
In stainless steel during compound straight-seam pipes tubulation welding, stainless steel side weld is uneven and uneven fusion, burn-through, weldering easily occurs
Situation about staying is stitched to occur；Improve the stability of tubulation welded seam shaping；It ensure that the abundant fusion of stainless steel side weld
And uniformity, effectively increase compound straight-seam pipes performance in stainless steel.It is compound in stainless steel using such scheme production
Straight-seam pipes, occur after 4Kg hydraulic test, phenomena such as no cracking, booster, weld seam leak, pipe and weld seam bearing capacity are excellent；
By national standard GB/T 246-2007《Flattening test on tube of metal method》Carry out relative 0 ° and 90 ° inspection of weld seam, weld seam flawless.
Brief description of the drawings
Fig. 1 is the cross section structure diagram that straight-seam pipes tubulation welds water cooling cushion device；
Fig. 2 is the mounting structure schematic diagram that straight-seam pipes tubulation welds water cooling cushion device；
Fig. 3 is the installation schematic cross-sectional view that straight-seam pipes tubulation welds water cooling cushion device.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As illustrated, straight-seam pipes tubulation welding water cooling cushion device includes the bracket 10 with connecting rod 13, support is arranged on
