Oblique wedge type barrel arbor decoiler on flying shear line

Abstract

Sloping Wedge sleeve barrel arbor decoiler on flying shear line, the invention involves cantilever axle of the transmission equipment. The sloping Wedge sleeve barrel arbor decoiler on flying shear line in the invention includes main axle, draft bar, cross cover and fixed ring, the main axle is equipped with axle sleeve, the out surface of axle sleeve is two or more conical bench installed axially or sloping wedges within same physical dimension and installed radially and uniformly, two or more bow plates in the same axle with axle sleeve cover the sloping wedges of axle sleeve, the inner surfaces of bow plates are equipped with sloping wedges corresponding with axle sleeve sloping wedges. The invention improves the original assembly sliding basement of main axle into whole sloping wedge sleeve, thereby extends main axle and can carry big tonnage roll bending. Because of extended main axle, the faying face of bow plate and inner barrel of spool is increased to forming whole face contacting, so can ensure the roll bending not torsional and distortion under the condition of self-strength is not enough in the last loops.

Description

technical field [0001] The invention relates to a conveying device of a sheet metal processing combined machine tool, in particular to a cantilever shaft of the conveying device. Background technique [0002] At present, the uncoiling processing of metal sheets is mostly completed by combined processing lines, in which there are uncoilers carrying steel coils. The original cantilever decoiler adopts an assembled wedge and sliding seat structure, the rigidity of the main shaft and the bow plate is poor, and the load limit is 12 tons. The weight of the coil is less than 12 tons, and the support shafts of these general structures can fully meet the requirements of such work. Nowadays, when uncoiling large-tonnage coils, double-head uncoilers are usually used for uncoiling, but double-head uncoilers cannot solve the damage to the inner layer of steel coils due to the short reel shaft and short load-bearing surface of the reel, especially for uncoiling. In the last few laps, th...

Problems solved by technology

Nowadays, when uncoiling large-tonnage coils, double-head uncoilers are usually used for uncoiling, but double-head uncoilers cannot solve the damage to the inner layer of steel coils due to the short shaft of the reel and the short load-bearing surface of the reel, especially for uncoiling. In the last few laps, the distortion caused by the insufficient rigidity of the steel ring itself cannot be corrected.
