Method of manufacturing of a formed product and use of the method

Abstract

The invention relates to a method of manufacturing a product ( 10 ) formed in a pressing tool, wherein the tool is also designed to carry out a cutting and/or punching operation on the product. The cutting operation/punching operation is incomplete, such that waste/scrap ( 33, 41; 52; 64 ) resulting from the cutting/punching operation remains with the product ( 10 ) when the product leaves the pressing tool. The waste/scrap ( 33, 41; 52; 64 ) is removed during a subsequent finishing. The waste/scrap ( 33, 41; 52; 64 ) remains with the product ( 10 ) via at least one connecting bridge ( 31, 42; 51; 61 ) or the like.

1 . Method of manufacturing a product ( 10 ) formed in a pressing tool, wherein the tool is also designed to carry out a cutting and/or punching operation on the product, characterised in that the cutting operation/punching operation is incomplete, such that waste/scrap ( 33 ,  41 ;  52 ;  64 ) resulting from the cutting/punching operation remains with the product ( 10 ) when the product leaves the pressing tool. 
     
     
         2 . Method according to  claim 1 , characterised in that the waste/scrap ( 33 ,  41 ;  52 ;  64 ) is removed during a subsequent finishing. 
     
     
         3 . Method according to  claim 1 , characterised in that the waste/scrap ( 33 ,  41 ;  52 ;  64 ) remains with the product ( 10 ) via at least one connecting bridge ( 31 ,  42 ;  51 ;  61 ) or the like. 
     
     
         4 . Method according to  claim 3 , characterised in that the connecting bridge ( 51 ;  61 ) is of reduced thickness in relation to the thickness of the material of the product ( 10 ) at a cutting point/punching point. 
     
     
         5 . Method according to  claim 3 , characterised in that the cutting operation/punching operation is carried out in such a manner that the connecting bridge ( 51 ) is partly sheared off. 
     
     
         6 . Method according to  claim 3 , characterised in that the cutting operation/punching operation is carried out in such a manner that the connecting bridge ( 61 ) is compressed. 
     
     
         7 . Use of a method according to  claim 1 , characterised in that the method is used in association with manufacture of press-hardened products so as to minimize or eliminate subsequent finishing of a hardened product. 
     
     
         8 . Use of a method according to  claim 1 , characterised in that the method is used in hot-forming of products, wherein the cutting operation/punching operation is carried out on a heated product. 
     
     
         9 . Use of a method according to  claim 1 , characterised in that the method is used in cold-forming of products. 
     
     
         10 . Use of a method according to  claim 3 , characterised in that the method is used in a simultaneous manufacture of at least two products, and in that the products remain together via at least one connecting bridge or the like. 
     
     
         11 . Method according to  claim 2 , characterised in that the waste/scrap ( 33 ,  41 ;  52 ;  64 ) remains with the product ( 10 ) via at least one connecting bridge ( 31 ,  42 ;  51 ;  61 ) or the like. 
     
     
         12 . Method according to  claim 4 , characterised in that the cutting operation/punching operation is carried out in such a manner that the connecting bridge ( 51 ) is partly sheared off. 
     
     
         13 . Method according to  claim 4 , characterised in that the cutting operation/punching operation is carried out in such a manner that the connecting bridge ( 61 ) is compressed. 
     
     
         14 . Method according to  claim 11 , characterised in that the connecting bridge ( 51 ;  61 ) is of reduced thickness in relation to the thickness of the material of the product ( 10 ) at a cutting point/punching point. 
     
     
         15 . Method according to  claim 14 , characterised in that the cutting operation/punching operation is carried out in such a manner that the connecting bridge ( 51 ) is partly sheared off. 
     
     
         16 . Method according to  claim 14 , characterised in that the cutting operation/punching operation is carried out in such a manner that the connecting bridge ( 61 ) is compressed. 
     
     
         17 . Use of a method according to  claim 2 , characterised in that the method is used in association with manufacture of press-hardened products so as to minimize or eliminate subsequent finishing of a hardened product. 
     
     
         18 . Use of a method according to  claim 2 , characterised in that the method is used in hot-forming of products, wherein the cutting operation/punching operation is carried out on a heated product. 
     
     
         19 . Use of a method according to  claim 2 , characterised in that the method is used in cold-forming of products.
