Abstract

The invention discloses an uncoiling, centering, clamping and conveying and trimming unit for a hot-rolled double-layer bimetallic composite coiled material / sheet material. The uncoiling, centering, clamping and conveying and trimming unit comprises a material conveying device, an uncoiling machine, a centering and clamping and conveying machine and a disc-type trimming and sheet shearing machine which are sequentially arranged along the advancing direction of a sheet material or a coiled material. By adopting the unit, the central line of the unit coincides with the central line of a plate strip, so that the size precision of the finished-product bimetallic composite material sheet is ensured, and the problem that subsequent disc shear trimming cannot be performed smoothly caused by difference between curvature radiuses of the inner and outer composite sheets of the composite material coil. According to the unit, the head of the bimetallic composite material coiled sheet introduced by the uncoiling machine is forcibly centered precisely; and then the bimetallic composite material coiled sheet is then clamped and conveyed to the disc-type trimming and sheet shearing machine, so that the disc-type trimming and sheet shearing machine can shear the two sides of the composite coiled sheet. According to the unit, a slitter edge cutting-off mechanism is also arranged at a slitter edge outlet of the disc-type trimming and sheet shearing machine, so that slitter edge materials are collected and utilized very conveniently; and meanwhile, precise centering of the finished-product sheet is also ensured, and product quality is improved. The unit is simple in structure and convenient for operation and repair.

Description

technical field [0001] The invention relates to the technical field of rolling processing equipment for metal materials in the metallurgical industry, in particular to a device for uncoiling and trimming hot-rolled double-layer bimetallic composite plates and / or coils. Background technique [0002] Bimetallic composite material is a new type of high-efficiency bimetallic energy-saving material with industrial pure iron, carbon steel, low alloy steel or low-priced stainless steel as the base layer and high-priced stainless steel, copper, industrial pure titanium, etc. as the multilayer. With good corrosion resistance and low cost, it is widely used in petroleum, chemical industry, salt industry, water conservancy and electric power, food processing and other fields. There are two types of hot-rolled double-layer bimetallic composite materials: coil and plate. Both are made of two carbon steel plates sandwiching two stainless steel plates. After welding and sealing, a composit...
