Definitions

  • the invention relates to the technical sector of machines, machine tools using the transformation of adiabatic energy.
  • Machines have been developed by the applicant with, in particular, a method and device for energy damping which has been the subject of the patent FR 2,859,935 .
  • figure 1 the operating diagram of the machine in the adiabatic cutting frame.
  • the principle is that the punch enters the sheet metal plate with a high speed. During the impact of the punch on the sheet metal plate, the part receives very localized mechanical energy. This energy does not have time to broadcast and creates an instant warm-up. The ejection of the cut portion is caused by the viscosity of the material coupled to the force exerted by the punch.
  • the implementation of this method is carried out with a machine which successively comprises a table of work (1), a bed base (2), located in the horizontal upper plane, and bearing on damping means (3) of the energy transmitted by the pressing means (4) of the ram type.
  • the damping means (3) are guided and maintained by vertical receiver blocks (5).
  • the bed base has a guide cavity of a vertical pusher (6) acting in thrust on a punch (7) itself guided by a support body (8) of the punch ensuring its guidance.
  • the end of the punch is arranged with one or more tools (7a-7b) for perforating the cutting sheet (9), which advances step by step (perpendicular to the plane of the drawing).
  • Means (10) arranged between the support body (8) of the punch and the work table of the machine, control the positioning and advance of the sheet, but so through openings allow the evacuation of parts cut.
  • This punch is raised vertically by sets of cylinders (11) which provide the different positions of the punch according to the punching steps.
  • the lifting cylinders of the punch are on the work table of the machine and encumber his environment.
  • the machine of the type using the transformation of adiabatic energy with a punch lifting device is remarkable in that the worktable and the guide block of the punch are arranged to constitute means allowing the positioning and the displacement of pairs of winding pushers arranged two by two in alignment and solicited by jacks arranged under the table working of the machine, the upper pusher sliding in the guide body being adapted to cooperate with the punch to lift according to certain operating phases.
  • the originality of the invention relating to the machine punching lift device lies in the removal of the jacks on the work table of the machine to allow free access to the tool for the operator during tool changes .
  • This is enabled by the use of the worktable and the punch guide block as means allowing the positioning and the limited vertical displacement of pairs of winding pushers arranged two by two in alignment and solicited by jacks arranged under the table working machine.
  • the number of cylinders (21) and thus the number of reassembly pushing elements (23) is previously defined by the manufacturer. These push elements (23) and their receiving cavity surround the evacuation cavity (20e) cut parts of the worked plate formed in the table of the machine.
  • the guide body (24) of the punch (25) In the upper part beyond the table of the machine is the guide body (24) of the punch (25) that is to say the movable part of the head of the machine.
  • the punch has a head (25a) protruding in the upper part of the guide body and wider in section than its middle portion (25b) guided in a bore (24a) of the guide body, the lower portion (25c) of the punch being arranged for receiving punching tools.
  • This guide body (24) conventionally surrounds the receiving die (26) of the cutting plate and the web guide (27) of said plate.
  • the punch head may be supported on means (28) whose function is described in another applicant's patent application.
  • lifting the jack by the pusher (30) is effected by means of the threshing wedge on which the cylinder head is supported. This wedge is pushed by the upper end of the pushers. In this case, the punch head is shorter and its mass reduced. This variant is not illustrated.
  • the punch cooperates directly or indirectly with the pusher (30)
  • the guide body is arranged with a plurality of holes (29) traversing vertically, and this being positioned in axial alignment of each of the cavities formed in the work table and allowing the passage of the pushing elements reassembly.
  • These holes (29) in number identical to that of the underlying cavities allow the positioning of a second winding pusher element (30).
  • Each pusher element (30) is longer than the height of the the guide body of the punch so as to overflow in the upper plane, in a head configuration (30a) shouldered greater section than the portion integrated in the guide body.
  • said head (30a) rests against the horizontal upper surface of the guide body.
  • the lower end (30b) of said pusher member does not protrude from the horizontal lower plane of the punch guide means.
  • the arrangement of these pusher elements (30) is such that they are facing lower on the head (25a) of the punch.
  • This implementation makes it possible to easily modify the position of the punching tools, after their starting by transverse removal of the tool block.
