Manufacturing process and end product of a wire-like rectangular section

Abstract

“MANUFACTURING PROCESS AND END PRODUCT OF A WIRE-LIKE RECTANGULAR SECTION”, described as a manufacturing process and end product of a wire-like rectangular section which, according to the characteristics thereof, possesses as a basic principle to provide the formation of a specific and proprietary manufacturing process for producing wire-like rectangular sections ( 1 ) specifically for the utilization in metallic wire cloths for containers, partitions, trays and similar items and having as a basis a fully acceptable substituting alternative for the wire raw material, possessing a high initial manufacturing cost, which is the utilization of flat steel parings ( 2 ) by means of a complete and sequential straightening and shaping procedure thereof so as to obtain a wire-like rectangular section ( 1 ) bent and dented to form a rectangular section.

1 .) “MANUFACTURING PROCESS AND END PRODUCT OF A WIRE-LIKE RECTANGULAR SECTION”, characterized in that it comprises a wire-like rectangular section ( 1 ) bent and dented to form a rectangular section and obtained from a complete and sequential straightening and shaping procedure of flat steel parings ( 2 ) such as carbon steel plate strips extracted from steel coils (flat steel sheet original shape in the steelworks) after the longitudinal cutting process (Slitter cutting) or flat steel strips originated from the cutting process of flat steel sheets, pre-cut in smaller parts, so as to form an end product whose shapes and internal and external arrangements are generated from a section which is progressively bent lengthwise ( 3 ) until the edges ( 4 ) meet each other thus changing its shape to something similar to a wire since the section thickness and width are the same size and similar to that of a rectangle whose sides are very close in size, the bent side possessing a round finish ( 5 ) and the side the edges meet ( 4 ) possessing a sharp corner ( 6 ) with a slight dent for a better finish.  
   
   
       2 .) “MANUFACTURING PROCESS AND END PRODUCT OF A WIRE-LIKE RECTANGULAR SECTION”, characterized in that it comprises a straightening stage in which flat steel parings ( 2 ) such as carbon steel plate strips (scrap from the flat steel sheet longitudinal cutting) or strips flat steel strips originated from the cutting process of flat steel sheets, pre-cut in smaller parts, are rolled directly in a coiler (an axis holding the scrap roller) (A); next, the strip end ( 2 ) is fed through a set of drive rollers (B) that pull the strip ( 2 ) through straightening rollers (C) to straighten it; subsequently, the strip ( 2 ) already straightened, goes through side rollers (D) that guide it to rotating knives (hardened steel rollers with sharp edges) (E) that cut the strip ( 2 ) to determine the final width thereof. Finally, the strip ( 2 ) is taken to the coiler (F) that forms the new coil of flat steel parings ( 2 ), straightened and with an adjusted width for later positioning in the shaping production line; and the shaping stage in which the coil of flat steel parings ( 2 ), straightened and with an adjusted width, is taken to the decoiler (G); next, the strip ( 2 ) is driven by rollers (H) and taken to the shaper (a set of cylinder heads with tools) (I) that gradually shapes (bends) the wire-like rectangular section ( 1 ) until it is fully bent (closed) with the edges pressed against each other; and finally, the wire-like rectangular section ( 1 ) goes through the non-stop moving guillotine cutter (J) that cuts it continuously to the desired length so as to generate a configuration which is similar to that of a wire with a slight circular section.
