Cutter adjusting process for aluminum coil butterfly cutter

Abstract

The invention discloses a cutter adjusting process for an aluminum coil butterfly cutter. According to the cutter adjusting process, a flat cutter as a lower cutter of the butterfly cutter, the technical problem of lower cutter marks caused by contact of an aluminum coil and a lower cutter sleeve due to too narrow or too wide contact surface between the cut aluminum coil and a lower cutter blade is solved by controlling the diameter difference between the flat cutter and the lower cutter sleeve, it is ensured that the aluminum coil is cut evenly, meanwhile, according to the cutter adjusting process, the overlapping amount of the cutter edge of the butterfly cutter is adjusted according to 1 / 2 of the thickness of the aluminum coil, and the shearing quality of an aluminum coil product is improved.

Description

technical field [0001] The invention relates to a knife adjusting process, in particular to a knife adjusting process for aluminum butterfly knives. Background technique [0002] As a new type of aluminum coil shearing knife, the butterfly knife has the advantages of convenient assembly, quick installation and adjustment, short process, high efficiency, and light weight. At present, the common butterfly knife is composed of an upper knife and a lower knife. The upper knife is cut by a thin blade tightened by a spring ring, and the lower knife is used for cutting with the lower knife sleeve. Compared with the commonly used disc knife, the butterfly knife There is no gap between the inner upper knife edge and the lower knife edge, so the butterfly knife can only control the cutting quality of the butterfly knife by adjusting the overlapping amount of the knife edge. If the adjusted butterfly knife does not match the aluminum coil, it will cause butterfly The knife jumps durin...

Problems solved by technology

At present, the common butterfly knife is composed of an upper knife and a lower knife. The upper knife is cut by a thin blade tightened by a spring ring, and the lower knife is used for cutting with the lower knife sleeve. Compared with the commonly used disc knife, the butterfly knife There is no gap between the inner upper knife edge and the lower knife edge, so the butterfly knife can only control the cutting quality of the butterfly knife by adjusting the overlapping amount of the knife edge. If the adjusted butterfly knife does not match the aluminum coil, it will cause butterfly The knife jumps during the cutting process, resulting in quality defects such as shear warping, gnawing, and overprinting of the lower knife on the surface of the aluminum coil, which seriously affects the shearing quality of the aluminum coil product.
