Multifunction hydraulic head suitable for being applied to machines for bending and forming metallic sheets

Abstract

A multifunction hydraulic head for use with forming and bending machines for sheet metal and/or metal profiles is equipped with carriages ( 15 ) that slide horizontally on guide and shift shafts. Each carriage ( 15 ) of the said machine is equipped with a bracket ( 17 ) that is integral with the respective carriage, the bracket supporting the interchangeable work assemblies ( 18, 19, 20, 21 ) which include a mobile matrix ( 22, 24, 26, 28 ) and a fixed pressing unit ( 23, 25, 27, 29 ); furthermore, the sheet metal ( 11 ) is inserted between the matrices and the pressing unit of the installed unit, to be spot processed by the said work assemblies in accordance with the desired shape.

1 . A multifunction hydraulic head for use with forming and bending machines for sheet metal and/or metal profiles, equipped with carriages that slide horizontally on guide and shift shafts, wherein each carriage of the said machine is equipped with a bracket that is integral with the respective carriage, the bracket supporting interchangeable work assemblies including a mobile matrix and a fixed pressing unit whereby a sheet metal is inserted between the matrices and the pressing unit of the installed unit, in order to be spot processed by said work assemblies in accordance with the desired shape. 
   
   
       2 . The head of  claim 1 , in which the said interchangeable work assemblies include at least one fastening unit. 
   
   
       3 . The head of  claim 1 , in which the interchangeable work assemblies include at least one embossing or bending unit. 
   
   
       4 . The head of  claim 1 , in which said interchangeable work assemblies include at least one punching unit. 
   
   
       5 . The head of  claim 1 , in which said interchangeable work assemblies include at least one picking or deep drawing unit. 
   
   
       6 . The head of  claim 2 , in which the fastening unit is equipped with a matrix and a pressing unit. 
   
   
       7 . The head of  claim 3 , in which the embossing or bending unit is equipped with a matrix and a pressing unit. 
   
   
       8 . The head of  claim 4 , in which the punching unit is equipped with a matrix and a pressing unit. 
   
   
       9 . The head of  claim 5 , in which the picking or deep drawing unit is equipped with a matrix and a pressing unit. 
   
   
       10 . The head of  claim 1 , in which any tool equipped with different templates may be mounted onto the support structure, depending on the processing to be performed on the sheet metal to be formed. 
   
   
       11 . The head of  claim 1 , in which the assemblies may be mounted onto any axis, including horizontal types, and may be mounted upside-down, that is in an orientation in which the lower element is placed over the top.
