400cm；
Step (2)：Left expansion link 7, right expansion link 17 is controlled to be in contraction state so that the both ends of pole 3 are respectively placed in
Between two roll shafts 2 of the left upper end of roll shaft case 1, between two roll shafts 2 of the right upper end of roll shaft case 20；Electric rotating machine 21 is opened, is made
Pole 3 is in rotation status；Bed material spray gun 12 and fabric spray gun 14 are opened, control mobile bar 5 is moved on automatically controlled track 6, made
Obtaining the upper end of mobile bar 5 promotes the 2# metal tubes 4 on pole 3 at the uniform velocity to be moved with 10cm/min speed to the place direction of 1# heating furnaces 10
It is dynamic (to allow 2# metal tubes 4 to move right, due to being continuously cased with metal tube, therefore 2# metal tubes on pole 3 along its length
4 move right during the metal tube on the right side of 2# metal tubes 4 can be promoted also to move right, so as to drive all sets on pole 3
Some metal tubes move right)；
Step (3)：Bar 5 to be moved moves to (i.e. mobile bar 5 moves to low order end) to greatest extent, closes bed material spray gun 12 and face
Expect spray gun 14；Close electric rotating machine 21；
Step (4)：Left expansion link 7, right expansion link 17 is controlled to be in elongation state until pole 3 is jacked up, so that
The both ends of pole 3 depart from respectively between two roll shafts 2 of the left upper end of roll shaft case 1, two roll shafts 2 of the right upper end of roll shaft case 20 it

Row sintering curing, bed material spray fabric after solidifying levelling, solidification are finally sintered to fabric, are adapted to spray in metal tube surface
Duplex coating.
The spraying coating process requirement sprayed again is first heated according to coating, metal tube needs first to be heated before spraying, but
The characteristics of metal tube cross section is smaller, Longitudinal extending is longer is allowed for, overall heating is carried out to it then needs larger build
Heating furnace, cost is higher, and the efficiency of heating surface is not very high, and in the metal tube laser heating paint finishing of the present embodiment, each
The structure of the cylindrical shape burner hearth for penetrating inside heating furnace in the horizontal direction, the cylindrical shape burner hearth and metal tube is equipped with heating furnace
It is adapted, the efficiency of heating surface is higher, and because cylindrical shape burner hearth simply extends in the horizontal direction, greatly reduces heating furnace and hanging down
The upward size of Nogata, has saved cost.
Metal tube is heated by the way of radiant heating in the prior art, exist one it is universal the problem of, i.e., it is golden
The heating and spraying process for belonging to pipe need substep to carry out, and metal tube takes out by after radiant heating, then by metal tube from heating furnace
Sprayed, can so cause metal tube certain temperature drop occur in surface in spraying, metal tube surface on the one hand can be made not to be
Sprayed at an established temperature, the temperature drop degree of another aspect metal tube surface is different so that each position of metal tube surface
The coating quality of metal tube surface can all be reduced by putting temperature difference, above-mentioned phenomenon in spraying.And the metal tube of the present embodiment connects
Continuous hot spraying system, passes through the promotion of the upper end of mobile bar 5 so that and the metal tube being continuously cased with pole 3 integrally at the uniform velocity moves,
Therefore metal tube is continuously heated and spray that (i.e. metal tube completion at the uniform velocity mobile is heated, and then metal tube gradually exposes
Cylindrical shape burner hearth, and metal tube exposes the part of cylindrical shape burner hearth and is sprayed-on coating immediately, metal tube does not expose cylindrical furnace
The part insulation of thorax so that temperature drop when metal tube surface is sprayed-on is minimum, and above-mentioned working method substantially reduces metal
Pipe heats and the time interval of spraying, the whole outer surface of metal tube almost are sprayed-on coating (i.e. in a stationary temperature
Metal tube surface temperature keeps uniformity along its length), realize metal tube " while heating while spray " function, significantly
Improve the coating quality of coating.At the same time, after metal tube surface is sprayed-on a coating, with the uniform velocity moving for metal tube
Meeting is immediately by heating stove heat below, it is achieved that metal tube sprays, the close linking before and after heating between process, metal
Pipe is sprayed-on just being heated immediately after coating, and enhances the effect of being heating and curing of coating, substantially increases the spraying of coating
Quality.It is emphasized that by the metal tube laser heating paint finishing of the present embodiment, metal tube can be carried out continuously to add
Thermal spray process, metal tube are continuously machined, and shorten the time-consuming of the whole hot spraying process of single metal pipe,
The Continuous maching processing of automation is realized, production efficiency is substantially increased, compares and be appropriate for large-scale continuous production.
It is emphasized that when needing to spray signal layer coating to metal tube, 1# heating furnaces 10, bed material spray gun need to be only used
12 and 2# heating furnaces 13；When needing to spray three layers or more than three layers of coating to metal tube, it can adaptably increase and add
The quantity of hot stove and the quantity of spray gun, realized disposably to the target of metal tube spraying multi-layer coatings with this.
The metal tube laser heating paint finishing of the present embodiment, operation and maintenance is convenient, and metal tube hot spraying process
Machinery is carried out, and is influenceed by operating personnel smaller；The metal tube laser heating paint finishing of the present embodiment, is being propped up by metal tube
Movement on bar 3 is heated, and can realize and the metal tube of different length is effectively heated；The metal tube of the present embodiment
Laser heating paint finishing, by being used cooperatively for supporting mechanism and travel mechanism, the laser heating spray of metal tube can be realized
Apply, overcome the deficiency that can only process a metal tube every time in the prior art.
Embodiment 2
The metal tube laser heating paint finishing of the present embodiment, its basic structure is same as Example 1, and its difference exists
In：In order to reduce temperature drop when metal tube is sprayed between heating furnace in the present embodiment, while in order to reduce spraying process
The coating of middle sprinkling influences surrounding environment, and horizontal positioned gap sleeve 29, gap set are provided between adjacent heating furnace
The internal diameter of pipe 29 is more than the internal diameter of cylindrical shape burner hearth, and spraying hole is offered on the gap sleeve 29 and is used to spray.
Embodiment 3
The application method of the metal tube laser heating paint finishing of the present embodiment, its basic step is same as Example 1, its
Difference is：The length of 1# heating furnaces 10 is 120cm, and the length of 2# heating furnaces 13 is 200cm, the length of 3# heating furnaces 15
For 450cm；In step (1), the heating-up temperature of three heating furnaces is set, wherein, the furnace temperature of 1# heating furnaces 10 is base material treatment temperature
100 DEG C of degree, the furnace temperature of 2# heating furnaces 13 is 140 DEG C of bed material sintering curing temperature, and the furnace temperature of 3# heating furnaces 15 is solid for fabric sintering
Change 400 DEG C of temperature；In step (2), control mobile bar 5 is moved on automatically controlled track 6 so that the upper end of mobile bar 5 is promoted on pole 3
2# metal tubes 4 with 20cm/min speed at the uniform velocity to the place direction of 1# heating furnaces 10 move.
Schematically the present invention and embodiments thereof are described above, this describes no restricted, institute in accompanying drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So if common skill of this area
Art personnel are enlightened by it, without departing from the spirit of the invention, without designing and the technical scheme for creativeness
Similar frame mode and embodiment, protection scope of the present invention all should be belonged to.
