Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil production, and particularly relates to an automatic material rod pulling and threading device for an aluminum coil. Background Art

[0002] Aluminum foil is a special material widely used in the fields of food, medicine, cosmetics and electronics. Its main features are light weight, corrosion resistance, good thermal conductivity and easy forming. The existing production method of aluminum foil includes the following steps: rough rolling, intermediate rolling, coiling, tempering, finishing rolling, slitting, annealing and packaging.

[0003] For example, the patent application number CN201510304101.2 discloses a double zero aluminum foil thickness difference rolling method, including:

[0004] Rough rolling: The cast aluminum foil billet is put into the rough rolling mill and lubricated with rolling oil. The reduction amount of each rough rolling pass is 0.24mm→0.115mm→0.06mm→0.03mm.

[0005] For intermediate rolling, the aluminum coils that have been rough rolled are put into the intermediate rolling mill and lubricated with rolling oil. The reduction of each pass of intermediate rolling is: 0.03mm→0.014mm, 0.03mm→0.0118mm.

[0006] For coil closing, the two thickness aluminum coils after intermediate rolling are trimmed by 10 mm on both sides and overlapped, and the middle is oiled with double-combined oil, to which 5%-15% by mass of lubricating oil is added.

[0007] Intermediate annealing: After the combined coils are rolled, the aluminum coils with specifications of (0.014mm+0.0118mm)*1240mm are subjected to high-temperature annealing. The temperature is raised to 170℃ to 190℃ in the annealing furnace within 2 hours and kept at this temperature for 4 to 8 hours. After 2-3 hours of cooling, the coils are taken out of the furnace.

[0008] Finishing rolling: The aluminum coil that has been intermediate annealed is put into the finishing rolling mill and lubricated with rolling oil. The reduction of each pass of finishing rolling is: 0.0258mm, i.e. 0.014mm+0.0118mm→0.011mm, i.e. 0.006mm+0.005mm.

[0009] Slitting: the obtained aluminum foil is cut into aluminum foil of designed width by a slitting machine.

[0010] The semi-finished products are degreased and annealed. After being cut, the semi-finished products are electrically heated to 200℃-220℃ in an annealing furnace and kept warm for 3-5 hours, then cooled to 175℃-185℃ and kept warm for 3-5 hours, and finally cooled and taken out of the furnace.

[0011] Packaging: The degreased and annealed aluminum foil is packaged in moisture-proof packaging and packed in boxes.

[0012] For example, the patent application number CN201310677586.0 discloses a production process of 8021 alloy double zero aluminum foil, which includes the following steps:

[0013] (1) The raw materials are prepared according to the proportions, and then smelted, refined, and hot-rolled to produce hot-rolled billets with a thickness of 3 mm.

[0014] (2) Cold rolling: The 3mm thick hot-rolled billet is rolled, deformed and coiled into a 0.24mm thick cold-rolled billet through a cold rolling mill.

[0015] (3) Recoiling and trimming: The 0.24 mm thick cold rolled billet is passed through a recoiling machine for trimming to obtain a 0.24 mm aluminum foil billet.

[0016] (4) Intermediate rolling: The intermediate rolling mill uses a low roughness roller, low pass reduction, and a high additive content process to produce a 0.24mm thick aluminum foil billet through four passes of 0.24mm-0.125mm-0.064mm-0.03mm-0.014mm to form a 0.014mm thick single zero aluminum foil billet.

[0017] (5) Surface annealing: 0.014 mm thick single-zero aluminum foil is subjected to surface annealing in an annealing furnace at 165°C for 10 hours to soften the surface of the aluminum foil, thereby achieving the purpose of reducing rolling load, refining and reducing pinholes.

[0018] (6) Finishing rolling: The single-piece aluminum foil billet with a thickness of 0.014 mm that has been surface annealed is rolled into two sheets by a finishing mill.

[0019] (7) Slitting: The double-coiled 0.006-0.007mm thick double-zero aluminum foil blank is rolled and sheared by a slitting machine to obtain a single sheet of 0.006-0.007mm thick double-zero aluminum foil.

[0020] (8) Annealing, degreasing and packaging: The above-mentioned single sheet of 0.006-0.007 mm thick 8021 alloy double zero aluminum foil is subjected to annealing furnace for tempering, degreasing and cooling, and then packaged to obtain the finished 8021 alloy double zero aluminum foil.

[0021] During annealing, the aluminum coil needs to be hung on a special bracket through a threading rod, so that multiple aluminum coils are hung on the bracket in an array, and then the bracket is sent to the annealing furnace for annealing. The threading rod passes through the tube core of the aluminum coil, which is usually a stainless steel tube, and its outer diameter (usually 65mm) is smaller than the inner diameter of the tube core (usually 76.2mm). After annealing, it is sent to the packaging process, and the threading rod needs to be removed from the tube core before packaging. In the packaging process, the aluminum coil is usually packaged manually. The weight of the threading rod is large (greater than 25kg), and the work intensity is high for the operator. In order to reduce the work intensity, this patent is specially designed for aluminum coils. An automatic threading rod removal device for aluminum coils. Utility Model Content
