For preventing aluminum pipe generation pit corrosion, be necessary to carry out preservative treatment in aluminum tube surfaces.
Because air conditioner connecting pipe belongs to elongated class pipe fitting, adopt modes such as plastic-blasting, mopping, dipping lacquer, passivation all to be difficult for realizing mass production, also be difficult for guaranteeing quality of product.Facts have proved, adopt heat-shrink tube, be wrapped on the aluminum pipe anticorrosionly by thermal shrinkage method, is best settling mode at present.Analyze its anticorrosion life-span and very high reliability is arranged qualitatively from the characteristic of heat-shrink tube.
The solidifying temperature of heat-shrink tube is in 160 ℃, the existing heat-shrink tube curing technology that is used for Cu-Al connecting pipe mainly adopts dual mode: first method, utilize welding torch flame that the Cu-Al connecting pipe that is with heat-shrink tube is heated, constantly pass heating from the middle to both ends, deaeration, shortcomings such as the heat of solidification draw, this method exist that speed is slow, heating is inhomogeneous, yield poorly, of poor quality, pipeline bending; Second method adopts tunnel electric furnace heating, for preventing that the copper aluminum pipe from pushing up on the electric furnace inwall, with connecting rod the Cu-Al connecting pipe string is passed through electric furnace together, therefore influenced efficiency, in addition, have also that power consumption is big, defectives such as labor intensity is big, yield poorly, pipeline bending.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provides a kind of metal tube pyrocondensation anticorrosive coat automatic solidification equipment.The automatic solidification equipment of metal tube pyrocondensation anticorrosive coat described in the utility model comprises: import promotion wheel, guide-localization piece, electric heating case, electric heater, outlet drag wheel, and described import promotes wheel and is arranged on the material feeding mouth place; Described guide-localization piece is arranged in the electric heating case, is the guide-localization piece of one group of (string) endoporus convergent; In the described electric heating case described electric heater is set; Described outlet drags wheel, is arranged on the back of electric heating case.
Described import promotes wheel, can make the Cu-Al connecting pipe that packages heat-shrink tube fast by the electric heating case;
Described guide-localization piece, make metal tube according to the direction of guide-localization piece guiding by the electric heating case, and because guide-localization piece effect, the direct of travel of metal tube is restricted, can not run into the electric heating chamber interior wall, do not need between the metal tube during by the electric heating case to connect, but just high-speed and continuous advance by connecting rod, be subjected to the high temperature action in the electric heating case, heat-shrink tube shrinks and wraps tightly on the metal tube surface;
Described outlet drags wheel, preferably one group, makes the metal tube that loses thrust power can break away from the electric heating case fast.
The automatic solidification equipment of metal tube pyrocondensation anticorrosive coat described in the utility model can also comprise the aligning wheel, and it promotes to take turns with import and links to each other, and irregular metal tube can be aligned.As not adopting the aligning wheel, then need and to enter this automatic solidification equipment behind the heat-shrink tube aligning.
The spacing of the guide-localization piece in the electric heating case is done suitably to adjust to can be controlled in 0～1000mm according to the caliber of metal tube.
The tapering of the guide-localization piece cone-shaped inner hole in the electric heating case changes suitably adjustment of do according to the spacing of guide-localization piece, and the tapering of cone-shaped inner hole can be controlled in 0～180 °.
The minimum-value aperture of the guide-localization piece in the electric heating case is determined according to the metal tube external diameter that is with heat-shrink tube.
The profile of guide-localization piece can be circular, also can adopt square.
Preferably the guide-localization piece conical surface in the electric heating case is coated with last layer heat-absorbing material or reflection material, to increase heat-conducting effect.
Preferably electrical-heating source or other thermals source are placed in the guide-localization piece, improve automatic solidification equipment service behaviour of pyrocondensation anticorrosive coat and economic performance.
For improving the traffic direction of strengthening Cu-Al connecting pipe, can before dragging wheel, import promotion wheel, outlet arrange the guide-localization piece.
In order to improve the heat insulation effect of electric heating case, can increase insulating interlayer at the inlet/outlet end of heating cabinet.
The utility model solidifies robot device by custom-designed metal tube pyrocondensation anticorrosive coat the metal tube that is with heat-shrink tube is heated, handle so that heat-shrink tube is shunk curing, this device can be realized following purpose: significantly improve product yield and quality; By raising labour efficiency, dwindle the size of oven, increase insulation layer thickness, increase the thermal baffle of turnover heating cabinet, reduce power consumption.
The utility model is applicable to various metal tubes, but is mainly used in Cu-Al connecting pipe or the aluminum pipe that split-type air conditioner is used.
