Description

Continuous rolling and punching device for ultrathin steel strip and application method thereof

Technical Field

The invention relates to the technical field of steel strip processing, in particular to an ultrathin steel strip continuous rolling and punching device and a using method thereof.

Background

The steel strip is a narrow and long steel plate produced by various steel rolling enterprises in order to meet the requirements of different industrial departments for industrially producing various types of metal or mechanical products, and at present, the processing devices for realizing continuous punching on metal plates or strips are mainly two types: the other is a rolling punching device which is formed by mutually matching a male die roller and a metal female die roller. Wherein, traditional stamping die includes mould and lower mould, go up the mould by the die shank, the upper die base, the terrace die, punch plate, stripper and guide pin bushing etc. and constitute, the lower mould is by the die, die holder and guide pillar etc. and constitute, during production, install the mould on general press or high-speed press, through decoiler, the levelling machine, servo feeding mechanism etc. convey the sheet material to the mould and carry out stamping process, on the one hand, because ultra-thin steel band is very thin, terrace die and die clearance are very little, the processing degree of difficulty is big, on the other hand, because the stripper constantly strikes ultra-thin steel band repeatedly, make the steel band warp easily, thereby produce bad defects such as banded ripples, cause the product to have not satisfied the.

The patent publication No. CN104475543B, entitled ultra-thin steel strip continuous rolling and punching device, realizes continuous punching on ultra-thin steel strip by utilizing the elastic fit of a metal mold core installed in an upper mold roller rubber cylinder and a lower mold roller surface rubber cylinder, because the upper and lower mold rollers both adopt rubber covered roller structures, the arrangement of correspondingly matched convex modules and concave mold holes on the two mold rollers is not needed, thereby not only greatly reducing the production cost of equipment, but also solving the influence of the abrasion of parts of a transmission mechanism on the matching precision of the two mold rollers, thereby effectively reducing the maintenance cost of the equipment, improving the production efficiency of the equipment, and effectively avoiding the extrusion deformation of the ultra-thin steel strip by the rubber covered roller with a smooth surface when the continuous punching is realized by the rolling fit of the two rubber covered rollers, improving the flatness of the steel strip, and simultaneously, the lower mold roller adopts the rubber covered roller with a smooth surface to avoid the metal scraps from staying on the surface of the lower mold roller, realize automatic discharge to effectively solved the problem that metal fragment blockked up die cavity easily among the prior art, but this patent has following defect in the use: 1. the distance between the upper die roller and the lower die roller is fixed, the device can only be suitable for steel belts with one thickness, but cannot be suitable for other steel belts with different thicknesses, the universality of the device is poor, and the use cost is increased undoubtedly; 2. after the steel belt is punched, waste materials are easily remained in the holes, the waste materials cannot directly fall off for collection, follow-up treatment is needed, the workload of steel belt processing is increased, and the production efficiency is reduced.
