Description
Sheet material providing reduction in cost of scrap materials in process of sheet metal materials and method to obtain such sheet material
THE RELATED ART
Invention relates to sheet metal materials used in many various sectors such as automotive, aviation, trains, heavy vehicles etc. in general.
Invention particularly relates to sheet material providing reduction in cost of discarded part (scrap) remaining outside of the main product after shaping during sheet metal materials shaping stage and cut and discarded and made from thinner and lower quality material in comparison to original product of discard product part, and a method to produce such sheet material.
BACKGROUND OF THE RELATED ART
Today sheet metal materials are used in many various sectors such as automotive, aviation, train, heavy vehicles. The sheet metal materials are shaped in molds to make them suitable for the structure of product to be produced.
In current related art during process of shaping sheet material, sheet material of sizes bigger than sheet to form main product is required to be used in order to be able to control sheet, that is, to keep sheet in the mold and tighten. After completion of process of shaping, the parts remaining outside of the final product on the shaped sheet material are cut and discarded. The discarded sheet materials increase cost of product. In addition, having discarded parts on sheet material makes the sheet material to be shaped heavier unnecessarily. Also cost of recycling the discarded sheet material increases in proportion to its weight.
When the related art is searched, application numbered EP2946845B1 is seen. Said application discloses a press-forming method for press-forming a final shaped article

However, it does not disclose a method providing replacement of sheet sections only performing duty of grasping inside form and cut and discarded after shaping and/or with thinner ones while performing shaping in the form and thus reducing amount of scrap.
In conclusion, developments have been made in sheet materials and, therefore, new embodiments eliminating the above disadvantages and offering solutions to existing systems are needed.

DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the preferred embodiments of the sheet material (19) being subject of this invention have been disclosed solely for the purpose of better understanding of the subject and described in a manner not causing any restrictive effect.
The invention relates to sheet material (19) used in obtaining final product (1 ) used in various sectors and providing reduction in cost of discarded material after shaping operation and it is characterized by comprising,
• a main product section (10) forming final product (1 ) by shaping, having the required thickness and quality features of the final product (1 )
• a scrap product section (12) connected to outer part of main product section (10) and cut and discarded after obtaining final product (1 ), having thinner and/or lower quality in comparison to main product section (10).
The invention also relates to a method for obtaining sheet material (19) used in obtaining final product (1 ) used in various sectors and providing reduction in cost of discarded material after shaping operation and it is characterized by comprising process steps of
• Cutting main product section (10) to form final product (1 ) from sheet material (16) having thickness and quality aspects required for final product (1 ), in the form matching final product (1 ),
• Cutting scrap product section (12) from a sheet material having lower thickness and quality aspects in comparison to main product section (10), in form convenient for connection to main product section (10) by outer section and in sizes convenient to provide fixing sheet material (19) inside the mold,
• Connecting main product section (10) and scrap product section (12) along connection line (1 1 ).
The sheet material (19) disclosed under the invention in general consists of a main product section (10) and a scrap product section (12). Said main product section (10) and scrap product section (12) are interconnected by means of a connection line (1 1 ).
Figure 1 shows an illustrative general view of the sheet material (19) being subject of the invention. Final product (1 ) to be obtained upon shaping sheet material (19) consists of a main product section (10) and scrap product section (12) located on outer section of the main product section (10) and providing control of sheet material
(19) inside the mold. Main product section (10) and scrap product section (12) are interconnected by means of a connection line (1 1 ).
Figure 2 shows an illustrative view of production stage of main product section (10) of sheet material (19) forming final product (1 ). Main product section (10) is made from a blanking sheet (16) having thickness and quality features required from final product (1 ) to be produced by means of cutting convenient to form of final product (1 ). Since final product (1 ) is desired to be made fully from main product (10), main product section (10) is cut slightly bigger than dimensions of outer line (17) to form final product (1 ).
Scrap product section (12) to be connected to outer section of main product section (10) is obtained by means of cutting from a sheet material similar to main product section (10). Scrap product section (12) is cut in a manner to surround main product section (10) from outside and convenient to form of main product section (10). In addition, scrap product section (12) is cut in a width to enable connection of sheet material (19) inside mold. Since scrap product section (12) constitutes the section to be cut and discarded after forming sheet material (19), it is produced from a sheet metal material having lower thickness and/or lower quality in comparison to main product section (10).
Main product section (10) cut in appropriate form and scrap product section (12) are interconnected by means of a connection line (1 1 ). Way of this connection is preferably provided by means of a laser welding operation applied along connection line (1 1 ). In alternative embodiments, this connection can also be provided in different ways.
Figure 3 is an illustrative view showing shaping sheet material (19) of the invention in form. According to the figure, the sheet material (19) is located between a female mold (13) and a male mold (14). In order to provide said location, sheet holders (15) are used and sheet material (19) is fixed between female mold (13) and sheet holders (15). Scrap product section (12) is compressed between the female mold (13) and sheet holders (15) and holding sheet material (19) is provided. After operation of fixing, when male mold (14) presses on female mold (13), the main
product section (10) remaining between male mold (14) and female mold (13) and partially scrap product section (12) are formed.
Figure 4 shows the sheet material (18) shaped from the form. Cutting operation is applied onto the shaped sheet material (18) along outer line (17) and final product (1 ) is obtained. Scrap product section (12) forms most part of sections cut from the shaped sheet material (18). However, when forming main product section (10), some part of main product section (10) is cut and can be discarded together with scrap product section (12) since some amount over blanking sheet material (16) is cut from outer line (17). However, since too big part of section cut from shaped sheet material (18) contains scrap product section (12) reduction of product cost provides reduction in recycling costs. In addition, sheet material (1 ) product weight is also reduced.
