The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
The continuously extruded coil pipe technology of a kind of aluminium and aluminium alloy concurrent flow pipe comprises the steps:
(1) cleans, aluminium bar is cleaned in the bar cleaning machine, remove aluminium bar surface and oil contaminant and dust, remove bar end face burr simultaneously.
Earlier aluminium bar 1 is cleaned in bar cleaning machine 2, cleaning machine 2 also possesses the function of removing bar end face burr when removing aluminium bar 1 surface and oil contaminant and dust, prevent that foreign matter from damaging extrusion die 5 and causing product to be mingled with bad in extrusion process.
(2) preheating is cleaned 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 defectives such as surface tear, avoid causing product to produce defectives such as layering, cracking, bubble.
(3) extruding, the aluminium bar after the preheating is admitted in the extrusion die in the forward extrusion machine and pushes, and forms the concurrent flow pipe of required size, and extrusion die needs in the mould pot arch, to carry out preheating before use.
Aluminium bar after the preheating is admitted to forward extrusion machine 4 and pushes, and after aluminium bar is out of shape through extrusion die 5 backs, forms the concurrent flow pipe 18 of required size, and extrusion die 5 needs in mould pot arch 6, carry out preheating before use.
(4) spray zinc; By closed spray zinc chamber, the automatic automatic spray Zn system formed of the spray zinc platform of electric arc zn spraying machine, location usefulness; Utilize compressed air that the zinc silk of arc-melting is atomized and blows out and be sprayed on product surface; Upper and lower surfaces to the concurrent flow pipe sprays the zinc processing simultaneously, forms the spray zinc layer of one deck even compact.
Automatic spray Zn system is set at the extruder outlet place; Automatically the 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 usefulness; Simultaneously the upper and lower surfaces of concurrent flow pipe 18 is sprayed zinc and handle, 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 atomized and blows out to be sprayed on product surface; Residual suspension zinc particle in the closed spray zinc chamber 9 is collected through dedusting pipeline 19 by two vertical filter cylinder secondary ash collectors 20 of whirlwind, prevents to pollute workshop condition.
(5) cooling makes the cooling of concurrent flow pipe through the cooling water tank that adopts recirculated water, and makes not fully the zinc zinc layer firm attachment of cooled and solidified at the concurrent flow tube-surface.
Spray zinc concurrent flow pipe 18 later can not contact any solid objects, and fully the zinc layer of cooled and solidified is uneasy is as yet wiped.Need make its cooling and firm attachment on concurrent flow pipe 18 surfaces through cooling water tank 10; Cooling water tank 10 adopts recirculated water to guarantee water temperature; In the product cooling procedure, have a small amount of zinc powder and fall in the water, filter pump 11 is installed in the recirculation water pipeline to prevent zinc powder polluted source water quality.
(6) oven dry; Dispel a small amount of cooling water moisture that the concurrent flow tube-surface is adhered to hot blast tunnel drying plant with the cold wind cutter and carry out the twin-stage processing; Compressed air in the cold wind cutter dries up most cooling waters of concurrent flow tube-surface, and the compressed air in the hot blast tunnel drying plant after the heating is thoroughly dried moisture;
After concurrent flow pipe 18 came out from cooling water tank 10, a small amount of cooling water can be adhered in the surface, if do not dry processing, bad phenomenon such as false alarm, reduction ink-jet ink marks adhesion can in subsequent handling, occur causing detecting a flaw.Adopt cold wind cutter 12 to dispel and carry out the twin-stage processing with 13 pairs of surface moistures of hot blast tunnel drying plant; Compressed air in the cold wind cutter dries up most cooling waters on concurrent flow pipe 18 surfaces, and the compressed air in the hot blast tunnel drying plant after the heating is thoroughly dried moisture.
(7) flaw detection ink-jet; Adopt automatic eddy current flaw detec that the concurrent flow pipe is detected a flaw; Lean out pin hole, be mingled with, ftracture, scratch after the defective signal is exported to defective sign ink jet printer; Defective sign ink jet printer is received the signal of automatic eddy current flaw detec, and behind the signal of forward extrusion machine and electric arc zn spraying machine automatically and the concurrent flow pipe speed of service that combines tachymeter to measure, implements ink-jet;
After the 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 defective sign ink jet printer 15 after the defectives such as cracking, scuffing; Defective sign ink jet printer 15 is received the signal of automatic eddy current flaw detec 14, and behind the signal of forward extrusion machine 4 and electric arc zn spraying machine 7 automatically and concurrent flow pipe 18 speeds of service that combine tachymeter 16 to measure, accurately implements ink jet process.Like this, the rejected region that position the when binding site between the aluminium bar, the unusual current interruption of spray Zn system and carrying out flaw detection go out can be identified out by automatic ink-jet, scraps so that choose in client's use.
(8) rolling is wound into coil pipe through four automatic winding-machines with product.
The continuously extruded coil pipe technology of aluminium of the present invention and aluminium alloy concurrent flow pipe; Collect continuously extruded, spray operations such as zinc, cooling, oven dry, flaw detection, defective sign, coiling in integrated; Automaticity is high; Process and steady quality, production efficiency is high, has successfully realized the continuous batch production of this product.
The sign at the defective position of product quality is more comprehensive, has not only identified the product defects that the eddy current inspection of prior art sign goes out, and has also identified binding site and the spray zinc of the extruded bar stock position when unusual 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 can't catch up with the product extrusion speed, and the problem of extrusion speed too high fusing of product surface temperature when slack-off.
Production process environmental protection, safety; Spraying on the one hand zinc carries out in that enclosed spray zinc is indoor; And adopt the vertical filter cylinder secondary ash collector of whirlwind to carry out zinc powder and collect, the zinc powder in the cooling water also focuses in water tank through the filter pump interception on the other hand, has effectively prevented the zinc powder contaminated environment.
