Problems solved by technology

[0003] However, when using the traditional slitting method for 12.5mm wide and narrow aluminum sheets, due to the stress of the raw materials, it is very easy to have a sickle bend during slitting, and the current requirements for the burrs of the slitting materials are changed from the original 0.05mm is reduced to 0.03mm, and the dimensional tolerance of the slitting material is reduced from the original ±0.1 to 0.05mm. These technical requirements cannot be realized according to the traditional slitting method

Embodiment Construction

[0015] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0016] A method for slitting a 12.5mm wide narrow strip aluminum plate is characterized in that it comprises the following steps:

[0017] (1) Clean the knife shaft: remove all the mesons on the knife shaft, pour clean water and anti-rust oil into the rag, clean the knife shaft with a rag, and ensure that the knife shaft is free from oil or dirt, and at the same time ensure that the side Hydraulic lock locked;

[0018] (2) Arrangement of cutters: Calculate the position of the central point of the cutter arrangement according to the size of the strips, and then clean the cutters and mesons and insert them into the cutter shaft. When the tool on the tool shaft is a male tool, the tool inserted into the lower tool shaft is a female tool, and then the tool is calibrated to ensure that the gap between the two sides of the group tool is consistent, and the control gap is ...

Abstract

The invention relates to a splitting method of a strip aluminum plate with 12.5mm width. The splitting method includes the following steps: (1) cutter shafts are washed; (2) an upper cutter shaft and a lower cutter shaft are guaranteed to be parallel, and group cutter gaps are consistent and are 0.3-0.5mm; (3) a skid plate is adjusted and cannot be loosened, and the skid plate can pull materials; (4) a bump-cutter machine is wiped and kept clean; (5) a brake is used during material loading, braking pressure is adjusted, and a steel belt is cut off after material loading is finished; (6) a partition shaft is used for rewinding, and simultaneously a plate pressing device is arranged; and (7) splitting quantity is guaranteed to be less than or equal to 15, boot time is 80m / min, simultaneously one half burr is controlled to be cut off, and one half burr is controlled to be cracked. Through effective control of cutter shaft cleaning, group cutter shaft parallelism, cutter gaps, skid adjustment, material loading, rewinding and boot, the splitting method of the strip aluminum plate with 12.5mm width can effectively avoid the problem of camber during splitting of strip aluminum and simultaneously meet requirements of dimensional tolerance and burr.

Description

technical field [0001] The invention relates to a slitting method of an aluminum plate, more specifically relates to a slitting method of a 12.5mm wide and narrow aluminum plate, and belongs to the technical field of aluminum plate cutting. Background technique [0002] The main function of the sheet metal slitting machine is to cut the wide roll material into narrow coils of a certain size along the length direction to prepare for other processing procedures in the future. It usually includes an unwinding mechanism, a leading material positioning mechanism, and a longitudinal The shearing mechanism and the winding mechanism, wherein, the slitting and slitting mechanism includes two rotating shafts driven by a motor in parallel up and down, a circular blade of steel material arranged on the rotating shaft, and a circular blade on the upper and lower rotating shafts. Correspondingly set in pairs, that is, set the upper circular blade as a male knife, then the lower part and i...
