A kind of sawing method of hot-rolled aluminum plate

Abstract

The invention discloses a sawing method of a hot-rolled aluminum plate. Step 1, installing an improved hot-rolled aluminum plate sawing machine and sawing an alloy saw blade; Step 2, preparing the hot-rolled aluminum plate sawing machine before starting up; Step 3, Control of the oil mist lubrication system; step 4, turn on the driving device of the roller table of the hot-rolled aluminum plate sawing machine; step 5, control the peripheral speed of sawing alloy saw blades; step 6, turn on the aluminum scrap recovery device; step 7, put it aside Cut hot rolled aluminum sheet. This sawing method for hot-rolled aluminum plates can effectively solve the problems of beveling, flattening and bending of the incision end face that occur when heavy-duty shearing machines cut aluminum plates, greatly reduces the sawing cost of sawing hot-rolled aluminum plates, and improves The smoothness and flatness of the sawing end surface are improved, the labor intensity of operators is reduced, the production efficiency of sawing aluminum plates is improved, and at the same time, aluminum scraps in the process of sawing aluminum plates are effectively recovered, which improves economic benefits.

Description

technical field [0001] The invention relates to the technical field of processing hot-rolled aluminum plates, in particular to a sawing method for hot-rolled aluminum plates. Background technique [0002] The thickness of the hot-rolled aluminum plate is mainly between 1.0㎜~200㎜. The blanking and cutting of the hot-rolled aluminum plate has always been a technical problem in the industry. The main problem is that the cut section is prone to unevenness, flattening, and bending; especially After rolling, the medium-thick aluminum plate with a medium thickness of more than 20mm is cut and blanked with a heavy-duty shearing machine at high temperature. Tolerance range; it is necessary to flatten both ends in the cold-pressed state and cut off the curved cutting head saw; to produce high-quality medium-thick plates, it is necessary to add a straightening machine to bend and twist the plates caused by shearing Leveling; thus, unnecessary processing procedures have been added, whi...

[0002] The thickness of the hot-rolled aluminum plate is mainly between 1.0㎜~200㎜. The blanking and cutting of the hot-rolled aluminum plate has always been a technical problem in the industry. The main problem is that the cut section is prone to unevenness, flattening, and bending; especially After rolling, the medium-thick aluminum plate with a medium thickness of more than 20mm is cut and blanked with a heavy-duty shearing machine at high temperature. Tolerance range; it is necessary to flatten both ends in the cold-pressed state and cut off the curved cutting head saw; to produce high-quality medium-thick plates, it is necessary to add a straightening machine to bend and twist the plates caused by shearing Leveling; thus, unnecessary processing procedures have been added, which is not conducive to the improvement of production efficiency, increases the input of equipment and labor costs, and also increases the labor intensity of operators; the inventor invented based on many defects of the prior art A hot-rolled aluminum plate online sawing method can solve the problems in the prior art, and the cost of the last hot saw is much lower than that of the last heavy shearer, and the replacement of the saw blade is cheaper than the replacement of the shearer blade. The cost is much lower, which greatly reduces the cutting cost of cutting hot-rolled aluminum sheets; realizes the sawing end face of hot-rolled aluminum sheets, which is smooth and smooth, and improves the yield rate. Recycling adds considerable economic benefits
