Definitions

  • the present invention concerns a multifunction hydraulic head for use with forming and bending machines for sheet metal and/or metal profiles.
  • the present invention refers to a multifunction hydraulic head that can be incorporated into forming and bending machines for sheet metal and metal profiles, in order to work sheet metal involving the following processes: punching, deep drawing or picking, embossing and fastening or cold welding.
  • the multifunction hydraulic head replaces the traditional system for processing panels and sheets, which until now have usually been obtained using processing techniques with dedicated machines, with the result that further processing involved the use of additional machines specially created for each processing stage.
  • the present invention has applications in the mechanical industry and in particular in the production of mechanical machines and equipment for processing metal sheets and panels in general.
  • a fixed bed to support the material, for example sheet metal, to be bent;
  • a punch being part of the press, and a corresponding counter-punch acting as means for clamping the material during the bending phase;
  • one or more bending blades that can be moved towards the material being processed
  • transducers or sensors of various types to control the process, connected to an electronic unit which controls the production process.
  • a bending machine of the type described above, marketed by the applicant, comprises a blade-holder structure with a “C” shaped cross-section, mobile in two reciprocally orthogonal directions with respect to the fixed bed, on which the bending blade(s) is (are) fixed.
  • a disadvantage of the known bending machines relates to the fact that the blade-holder structure employs bending tools whose use is rather limited, that is, generally only suitable for bending sheet metal.
  • sheet metal is also subject to further processing, for example it must undergo operations involving punching, deep drawing or picking, embossing and fastening, which involve almost fixed cold welding using special forming punches, or other operations to be performed with regard to the edges or the angular parts of the structure.
  • This processing method does not produce high-quality finished products, and in addition it is not possible to perform the processing on a continuous basis or with the same machine, as a result of which processing takes longer from an operational point of view, which makes it awkward to synchronize all of the various phases, particularly when dealing with a large number of parts to process.
  • the present invention proposes to provide a multifunction hydraulic head for use with forming and bending machines for sheet metal and/or metal profiles capable of eliminating or at least reducing the disadvantages described above.
  • the invention proposes to provide a multifunction hydraulic head for use with forming and bending machines for sheet metal and/or metal profiles capable of increasing the working capacity of the forming machine, adding functionality that was previously not available.
  • the device according to the invention proposes a basic purpose of making it possible to work sheet metal pieces, including those that are large in size, so that the above processes may be performed using a single multi-function machine.
  • a multifunction hydraulic head for use with forming and bending machines for sheet metal and/or metal profiles that comprise a fixed bed for supporting the sheet metal being processed, a frame intended to support a toolholder structure on at least one carriage, preferably on a pair of carriages, that move in opposite directions along parallel worm screws, along a horizontal axis, in relation to a press that is suitable for clamping the piece of sheet metal during the bending process.
  • work assemblies which are the subject of the invention are mounted that are interchangeable in relation to a common support structure, the said support structure being substantially C-shaped or in a shape that is suitable to contain the main body of the working head, which is accordingly integral with each carriage, and which is equipped with processing tools in the form of a fastening unit, an embossing or bending unit, a punching unit and a picking or deep drawing unit.
  • Each of the said units house various tools that are suitable for all types of processing so that, in order to perform a particular type of operation on the sheet metal, the operator need only mount the processing tools onto the carriage/s, choosing the most appropriate tool for the purpose at hand.
  • FIG. 1 shows a frontal schematic view of the machine equipped with at least one multifunction hydraulic head according to the invention as a whole;
  • FIG. 2 shows a lateral schematic view of the machine fitted with the multifunction hydraulic head placed in relation to of the central processing unit
  • FIG. 3 shows a lateral schematic view of one of the multifunction hydraulic heads according to the invention represented by the fastening unit
  • FIG. 4 shows a lateral schematic view of one of the multifunction hydraulic heads according to the invention represented by the embossing or bending unit;
  • FIG. 5 shows a lateral schematic view of one of the multifunction hydraulic heads according to the invention represented by the punching unit
  • FIGS. 6 and 7 show lateral schematic views of one of the multifunction hydraulic heads according to the invention represented by the picking or deep drawing unit respectively in a lowered working phase, in contact with the piece and in a raised phase.
  • a forming and bending machine 10 for sheet metal and/or metal profiles comprises a fixed bed that is not shown, for supporting the sheet metal 11 to be processed, which remains clamped against the same pressing element 12 placed against a fixed lower element 13 where the panel is inserted to be held in a horizontal position.
  • the machine 10 also has a frame 14 whose purpose is to support a pair of carriages 15 placed on revolving helical arbors 16 or worm screws, allowing translation in a horizontal direction of the carriages.
  • Each carriage 15 is equipped with its own multifunction hydraulic unit according to the invention, which are all mounted onto a bracket 17 that is integral with the respective carriage and which are accordingly arranged in a symmetrical fashion around the centre of the machine.
  • the bracket 17 supports the work assemblies that are the subject of the invention, which are made up of the units shown in FIGS. 3 to 6 , or a fastening unit 18 ( FIG. 3 ), an embossing or bending unit 19 ( FIG. 4 ), a punching unit 20 ( FIG. 5 ) and a picking or deep drawing unit 21 ( FIGS. 6 and 7 ).
  • Each of the aforementioned work units is equipped with an upper work element or matrix and a lower fixed punch element, whose shape depends on the matrix template.
  • the panel or an edge thereof to be processed is inserted and placed onto the lower pressing element, so that, upon a command entered by an operator or by means of preset automatic commands, the mobile upper element or matrix comes into contact with the panel to be processed, pressing and forming it in accordance with the desired shape using the relevant pressing unit.
  • the fastening unit 18 is equipped with a matrix 22 and a pressing element 23
  • the embossing or bending unit 19 is equipped with a matrix 24 and a pressing element 25
  • the punching unit 20 is equipped with a matrix 22 and a pressing element 23
  • the picking or deep drawing unit 21 is equipped with a matrix 28 and a pressing unit 29 .
  • FIGS. 6 and 7 indicate an example of how the forming assembly operates, and in this case the picking or deep drawing assembly 21 presents the work tool 28 respectively in a lowered position and in contact with the sheet metal and in a raised position.
  • Any other tool equipped with templates other than those illustrated and described may be mounted onto the support structure 17 , according to the type of processing to be performed on the sheet metal to be formed.
  • the forming assemblies can also be mounted onto any axis, including horizontal types and even upside-down, that is in an orientation in which the lower element is placed over the top.
