The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The parallel stream of aluminium and aluminium alloy is managed a continuously extruded coil pipe technique, comprises the steps:
(1) clean, aluminium bar is cleaned in bar cleaning machine, remove aluminium bar surface and oil contaminant and dust, remove bar end face burr simultaneously.
First aluminium bar 1 is cleaned in bar cleaning machine 2, cleaning machine 2, when removing aluminium bar 1 surface and oil contaminant and dust, also possesses the function of removing bar end face burr, prevents that foreign matter from damaging extrusion die 5 and causing product to be mingled with bad in extrusion process.
(2) preheating, cleans aluminium bar later and will in hanging type Medium frequency induction pot arch, be preheating to 420-480 ℃.
Clean aluminium bar 1 later and will in hanging type Medium frequency induction pot arch 3, be preheating to 420-480 ℃, the advantage of hanging type Medium frequency induction pot arch 3 is: firing rate is fast, aluminium bar does not contact with body of heater, can not cause the defects such as surface tear, avoid causing product to produce the defects such as layering, cracking, bubble.
(3) extruding, the aluminium bar after preheating is admitted in the extrusion die in forward extrusion machine and pushes, and forms the concurrent flow pipe of required size, and extrusion die need carry out preheating before use in mould pot arch.
Aluminium bar after preheating is admitted to forward extrusion machine 4 and pushes, and after aluminium bar is out of shape after extrusion die 5, forms the concurrent flow pipe 18 of required size, and extrusion die 5 need carry out preheating before use in mould pot arch 6.
(4) spray zinc, by closed spray zinc chamber, automatic spray Zn system that automatically the spray zinc platform of electric arc zn spraying machine, location use forms, utilize compressed air that the zinc silk of arc-melting is carried out to atomization and blow out being sprayed on product surface, the upper and lower surface of concurrent flow pipe is sprayed to zinc simultaneously and process, form the spray zinc layer of one deck even compact.
Automatic spray Zn system is set at extruder outlet place, automatically spray Zn system is by closed spray zinc chamber 9, eight automatic electric arc zn spraying machines 7 have been located spray zinc platform 8 compositions of use, the upper and lower surface of concurrent flow pipe 18 is sprayed to zinc processes simultaneously, form the spray zinc layer of one deck even compact, spray zinc is to utilize compressed air that the zinc silk of arc-melting is carried out to atomization and blow out being sprayed on product surface, residual suspension zinc particle in closed spray zinc chamber 9 is collected by dedusting pipeline 19 by two vertical filter cylinder secondary ash collectors 20 of whirlwind, prevents from polluting workshop condition.
(5) cooling, by adopting the cooling water tank of recirculated water to make concurrent flow pipe cooling, and make not fully the zinc zinc layer firm attachment of cooled and solidified at concurrent flow tube-surface.
Spray zinc concurrent flow pipe 18 later can not contact any solid objects, and not yet fully the zinc layer of cooled and solidified is easily wiped.Need to make its cooling and firm attachment on concurrent flow pipe 18 surfaces by cooling water tank 10, cooling water tank 10 adopts recirculated water to guarantee water temperature, in product cooling procedure, have a small amount of zinc powder and fall in water, filter pump 11 is installed to prevent zinc powder polluted source water quality in recirculation water pipeline.
(6) dry, with cold wind cutter, dispel a small amount of cooling water moisture concurrent flow tube-surface being adhered to hot blast tunnel drying plant and carry out twin-stage processing, compressed air in cold wind cutter dries up most cooling waters of concurrent flow tube-surface, and the compressed air in hot blast tunnel drying plant after heating is thoroughly dried moisture;
Concurrent flow pipe 18 from cooling water tank 10 out after, a small amount of cooling water can be adhered in surface, if do not carry out drying and processing, the false alarm that can occur causes detecting a flaw, reduces the bad phenomenon such as ink-jet ink marks adhesion in subsequent handling.Adopt cold wind cutter 12 to dispel with hot blast tunnel drying plant 13 effects on surface moisture and carry out twin-stage processing, compressed air in cold wind cutter dries up most cooling waters on concurrent flow pipe 18 surfaces, and the compressed air in hot blast tunnel drying plant after heating is thoroughly dried moisture.
(7) flaw detection ink-jet, adopt automatic eddy current flaw detec to detect a flaw to concurrent flow pipe, lean out pin hole, be mingled with, ftracture, scratch and signal is exported to after defect to defect sign ink jet printer, defect sign ink jet printer is received the signal of automatic eddy current flaw detec, and forward extrusion machine and automatically after the signal of electric arc zn spraying machine and the concurrent flow pipe speed of service of measuring in conjunction with tachymeter, implement ink-jet;
After oven dry, adopt 14 pairs of concurrent flow pipes 18 of automatic eddy current flaw detec to detect a flaw, lean out pin hole, be mingled with, signal exported to defect sign ink jet printer 15 after the defect such as cracking, scuffing, defect sign ink jet printer 15 is received the signal of automatic eddy current flaw detec 14, and forward extrusion machine 4 and automatically after the signal of electric arc zn spraying machine 7 and concurrent flow pipe 18 speeds of service of measuring in conjunction with tachymeter 16, accurately implement ink jet process.Like this, the rejected region that the position when binding site between aluminium bar, the abnormal current interruption of spray Zn system and carrying out flaw detection go out can be identified out by automatic ink-jet, to choose and scrap in client's use procedure.
(8) rolling, is wound into coil pipe by four automatic winding-machines by product.
The parallel stream of aluminium of the present invention and aluminium alloy is managed continuously extruded coil pipe technique, collect the operations such as continuously extruded, spray zinc, cooling, oven dry, flaw detection, defect sign, coiling in integrated, automaticity is high, process and steady quality, production efficiency is high, has successfully realized the continuous batch of this product and has produced.
The sign at the defective position of product quality more comprehensively, has not only identified the product defects that the eddy current inspection of prior art sign goes out, and has also identified the binding site of extruded bar stock and spray zinc position when abnormal simultaneously.
The oven dry of product, has designed the secondary drying course of cold wind cutter, hot blast tunnel drying plant, and solve common heating mode drying rate and cannot catch up with product extrusion speed, and the problem of extrusion speed product surface excess Temperature fusing when slack-off.
Production process environmental protection, safety, spraying on the one hand zinc carries out enclosed spray zinc is indoor, and adopting the vertical filter cylinder secondary ash collector of whirlwind to carry out zinc powder collection, the zinc powder in cooling water is also tackled in water tank and is focused on by filter pump on the other hand, has effectively prevented zinc powder contaminated environment.
