Definitions

  • the invention relates to manufacturing sector, wherein it relates to a die assembly which allows performing sheet metal forming processes with a single press and to a line system integrated with said die assembly.
  • the invention particularly relates a die assembly which allows performing sheet metal forming processes at a single stroke with a single press and to a line system integrated with the die assembly.
  • Hot and cold rolled flat sheet metals manufactured for forming purposes are formed into various shapes using mechanical and hydraulic presses.
  • Sheet forming process includes bending, stretching, deep drawing, or various combinations of these basic methods. Sheet forming is performed between the punch (male die) and the matrix (female die).
  • the first one of said manufacturing techniques is to make dies with the same number as the operations, and then to perform manufacturing with different presses.
  • the workpiece is made into final product after various operations performed thereon. This process comprises several operations including deep drawing, trimming, piercing, bending, etc. In this case, the workpiece is obtained after as many processes as the number of operations.
  • Another manufacturing technique is the so-called "progressive die” process in which different operations are combined in the same die and step by step manufacturing is performed. In this case, the workpiece is obtained after as many strokes as the number of operations.
  • the manufacturing process is faster compared to the former technique. This is because the movement of the workpiece between the presses and an operator-dependent operation are eliminated.
  • the manufacturing process using a progressive die is the technique where the desired workpiece is obtained by simultaneously performing more than one trimming, piercing, drawing, bending, profile operations, etc. at each stroke of the press, instead of advancing the material strip.
  • the operations to be performed with more than one press otherwise can be performed using a single press and running consecutive operations.
  • Progressive dies are the dies in which the material strip is advanced to perform more than one operation, a series of processes, alternately.
  • a process performed using dies with a pressing capacity of 40-50 tons in average in more than one operation has started to be performed using a single press of 300 tons or more.
  • An alternative method has always been sought for due to the costs of the high-tonnage eccentric presses used for these operations and the difficulty of manufacturing methods.
  • the typical operations of sheet forming, i.e. forming and trimming operations are each performed in a separate die and with a separate press operation.
  • progressive forming and transferring method is envisaged and progressive dies and transfer dies are manufactured therefor. A manufacturing mode apart from these does not exist in the state of the art.
  • the International Patent Application No. DE2018207 discloses a sheet metal processing machine which allows forming sheet metals in one operation in one workstation.
  • the International Patent Application No. FR2377855 discloses a multiple stamping press for sheet metal having separate and independent stations.
  • the invention aims to solve the problems mentioned above, overcome all the disadvantages, and provide additional advantages to the configuration.
  • the object of the invention is to perform all the processes of the sheet metal piece (forming, trimming) at a single stroke, in a single operation (in the same section), and with a single press, at the same time preserving the quality of the workpiece.
  • a die assembly suited for said process and a line system adapted to said die assembly for mass production have been designed.
  • the number of operations and equipment for sheet metal manufacturing will be reduced according to the invention. Hence, the efficiency of the production will be increased, labor demand will be decreased, saving on time will be achieved, and thereby increasing the production capacity.
  • Fig. 1 shows the die assembly for forming sheet metal and the line system integrated with said die assembly.
  • Line system 10. Coil feeder 20. Driver 30. Press 31 . Die assembly 40. Scrap discharging conveyor DETAILED DESCRIPTION OF THE INVENTION
  • the line system (1 ) generally comprises a coil feeder (10), a driver (20), a press (30), a die assembly (31 ), and a scrap discharging conveyor (40). (See Fig. 1 )
  • the coil feeder (10) is the configuration where the sheet metal in coil is located. Said coil feeder (10) has a sheet metal feeding capacity of 60 m/min.
  • the driver (20) straightens the sheet metal coming from said coil feeder (10) in an inclined manner according to the cutting process and drives the same to the press (30) continuously.
  • the scrap discharging conveyor (40) is the configuration which allows discharging the scraps of the sheet metal resulting from the cutting process, out of the press (30).
  • Said press (30) is a hydraulic press and performs the desired forming processes on the sheet metal by means of the die assembly (31 ).
  • the die assembly (31 ) is capable of performing more than one operation at a single stroke with a single press.
  • the working principle of the line system (1 ) is as follows: said coil feeder (10) and the driver (20) orient the sheet metal towards the press (30) at a defined speed.
  • the die assembly (31 ) which is connected to said press (30) and where all operations are combined allows performing all the desired operations on the sheet metal by stroking the target sheet metal at a single stage, at a single stroke, and in the same section. This cycle continues and sheet metal piece manufacturing process is performed along one line. At each stroke, all of the operations are performed in the same section and 1 workpiece is thus manufactured.
  • the distinctive feature of the present die assembly (31 ) from the progressive die is that the latter performs manufacturing with consecutive operations.
  • the die assembly (31 ) included in the line system (1 ) is capable of performing all the forming, trimming operations at a single stroke and in the same section.
  • the scrap resulting from the operation are discharged from said press (30) by means of the scrap discharging conveyor (40), without requiring an operator.
