鋁卷 慣例的穿孔針揉捏法揉捏管材的較大外徑為600～650mm主動(dòng)歸集，▽較小內徑5～15mm轉型升級，較小壁厚2～5mm。因為穿孔針的強度與剛性上的原因，ⅵ揉捏拉拔管管材的較小內徑與壁厚遭到較大的約束。其間行業(yè)運轉鋁卷，2015-7-2114:30:22軟鋁合金管材的較小內徑與較小壁厚可取上述規模的下限，硬鋁合金則取其上限。較近，♂當管材的外徑較大時(shí)價(jià)差增大，管材的較小壁厚
The maximum outer diameter is 600-650 mm, the minimum inner diameter is 5-15 mm, and the minimum wall thickness is 2-5 mm. Because of the strength and rigidity of the piercing needle, the minimum inner diameter and wall thickness of the kneading and kneading drawing pipe are greatly constrained. The minimum inner diameter and wall thickness of soft aluminium alloy pipe can be taken as the lower limit of the above scale, while hard aluminium alloy can be taken as the upper limit during the operation of aluminium coil industry from July 2015 to 2114:30:22. Recently,, when the outer diameter of the pipe is larger, the price difference increases, and the minimum wall thickness of the pipe increases.
慣例的穿孔針揉捏法揉捏管材的較大外徑為600～650mm鋁卷，㈥較小內徑5～15mm，ⅷ鋁卷的作用較小壁厚2～5mm。因為穿孔針的強度與剛性上的原因，⑾揉捏拉拔管管材的較小內徑與壁厚遭到較大的約束。
Conventional pin kneading method is used to knead the tube with the maximum outer diameter of 600-650 mm aluminium coil, six minimum inner diameter of 5-15 mm, and the minimum wall thickness of aluminium coil of 2-5 mm. Because of the strength and rigidity of the piercing needle, the minimum inner diameter and wall thickness of the kneading and kneading drawing pipe are greatly restricted.
其間需求回升，軟鋁合金管材的較小內徑與較小壁厚可取上述規模的下限，&硬鋁合金則取其上限。較近，鋁卷出產(chǎn)廠(chǎng)家當管材的外徑較大時(shí)，管材的較小壁厚通常以不小于管材外徑的5%為宜。外徑500mm以上的管材多選用反揉捏法成形。
In the meantime, the minimum inner diameter and wall thickness of soft aluminium alloy pipe can be taken as the lower limit of the above scale, while that of hard aluminium alloy pipe can be taken as the upper limit. Recently, when the outer diameter of the tube is large, the minimum wall thickness of the tube is usually not less than 5% of the outer diameter of the tube. Most of the pipes with diameter over 500 mm are formed by reverse kneading.

選用Confrom分流模揉捏，鋁卷執行規范可以成形與穿孔針揉捏法相比壁厚薄而均勻、偏心小的管材。但考慮到焊縫質(zhì)量問(wèn)題，Ⅰ在同一揉捏設備上所能成形的較大管材外徑或用同一揉捏筒所能揉捏的管材外徑比穿孔針揉捏法揉捏時(shí)要小。
By using Confrom shunt die kneading, the aluminium coil execution specification can form thin, uniform and small eccentricity pipe compared with the pin kneading method. However, considering the quality of weld seam, I. The maximum outside diameter of pipe that can be formed on the same kneading equipment or that can be kneaded with the same kneading cylinder is smaller than that when kneading with a perforating needle.
跟著(zhù)冷軋管和拉拔管技術(shù)的不斷改進(jìn)，回鋁合金管的較小壁厚可達0.1～0.2mm或更薄。
Company has learned that with the continuous improvement of cold rolling and drawing technology, the minimum wall thickness of aluminium alloy tubes can reach 0.1-0.2 mm or thinner.
較近在350 MN大型立式揉捏機上(反揉捏)出產(chǎn)揉捏管的較大直徑可達l500mm；在196 MN臥式揉捏機上可達l000mm。
Recently, the maximum diameter of kneading tube produced on 350 MN vertical kneading machine (reverse kneading kneading machine) can reach L500 mm, and l000 mm on 196 MN horizontal kneading machine.
揉捏管的較小外徑可達5mm。
The minimum outer diameter of kneading pipe can reach 5 mm.
冷軋薄壁管較大直徑可達120mm以上，ⅴ較小直徑在15mm以下。冷拉薄壁管的直徑為3～500mm力氣跑辦，用旋壓法則可軋出直徑達3000 mm的薄壁大管。
The maximum diameter of cold-rolled thin-walled tube can be more than 120 mm, and the minimum diameter can be less than 15 mm. The diameter of cold-drawn thin-walled tube is 3-500 mm, and the thin-walled tube with diameter of 3000 mm can be rolled by spinning method.
