  • the present invention aims to provide an electromechanical press meeting these needs.
  • the press of the invention is characterized in that the electromechanical actuating device comprises at least one electric motor of the Torque type with an eccentric axis arranged in kinematic connection with the forming device, the electromechanical actuating device being supported on the frame in a secant position of the plane P2 of displacement of the forming device and located between a base of the frame on the ground and the work table under the work plane P1 while the forming tool is maintained in all positions in or above above the work surface P1 of the work table, the work table being secured to the frame.
  • the press of the invention thus has a more compact and more stable structure due to the integrated, substantially central arrangement of the actuating device and more particularly of its Torque motor under the work table and in the plane of movement of the cutting tool. work.
  • Torque motor gives the press of the invention unparalleled versatility and flexibility of operation.
  • the use of a torque motor in fact allows direct drive of the forming device, without reduction gears, with high torque and high reactivity. It also has other advantages described more particularly below.
  • the frame comprises partitioning walls fixed integrally on the work table and the anchoring base so as to fit the electromechanical actuation device on the frame.

  • These displacement and adjustment means may in particular comprise a trapezoidal screw for adjusting the bottom dead center of the forming tool mounted on the crosspiece. In addition, this allows compensation for expansion during the day and tool wear.
  • the actuation device is arranged to move in translation along the Y axis relative to the work table on the frame.
  • the actuating device is slidably mounted on the frame by means of complementary linear guide members fixed to the actuating device and the frame and in kinematic connection with a linear displacement motor assembly in translation along the Y axis relative to the worktable.
  • This sliding assembly of the actuation device of the press is particularly advantageous for offering great versatility and simplicity of adjustment of the press.
  • the actuating device By moving the actuating device, it is not only the latter but also the forming device which is kinematically linked to it at the level of the connecting rods which is mobilized along the Y axis, and which is therefore adjusted in position with respect to to the work table, which defines the reference plane P1 of the press.
  • the motor assembly may in particular comprise a hydraulic piston or a flywheel integral with a worm screw.

  • the press of the invention can also offer an even more scalable configuration by the possibility offered of varying its power by associating in the actuation device a plurality of electric motors of the Torque type electrically mounted in series and kinematically coupled one to the other at their respective drive shafts.
  • the present invention relates to an electromechanical press 1 for forming parts by deformation and/or cutting of material in a sample, represented in a first preferred embodiment to the figures 1 to 3 and to figure 4 and 5 in a second preferred embodiment.
  • the press 1 comprises in the first place a frame 2 on which is mounted an electromechanical device 4 for actuating a device 3 for forming parts according to a reciprocating movement in translation in a vertical plane P2 of the press 1.
  • the forming device 3 is arranged in kinematic connection according to a form described below with the actuation device 4 so as to move a forming tool 35 integral with the forming device 3 in the movement back and forth to and from a work table 5, fixed to the frame 2 and immobile on the latter.
  • the forming tool 35 can be of various types depending on the forming operation to be carried out, in particular cutting, stamping, stamping or recovery, for example.

  • the work table 5 has an opening located in the middle of the work tool 35 in order to provide a clearance space for the stamping chips with each strike of the forming tool.
  • the vertical plane P2 in which the forming device 3 is moved is perpendicular and secant to the work plane P1 of the table 5.
  • the frame 2 consists of a weighted base formed of a metal or concrete plate 23 under which are fixed feet 22, adjustable if necessary.
  • four pillars 21 formed for example of metal beams are anchored to the base, by any suitable means such as bolting and/or welding and/or embedding. These pillars 21 support at their upper end the worktable 5, itself firmly anchored on the pillars 21.
  • the frame 2 and the worktable 5 can be formed in a one-piece assembly, typically metallic.
  • reinforcing brackets 24 are fixed at the angles between each of the pillars 21 and the plate 23 on the one hand and the pillars 21 and the table 5 on the other hand.
  • a rigid and stable frame 2 is thus obtained on which the electromechanical actuation device 4 is installed and with respect to which the forming device 3 is moved by the latter as described below.
  • the pillars 21 are replaced by 4 partitioning and stiffening walls 25 preferably formed by forging steel or aluminum alloy, these walls 25 being anchored to the base 23 and to the work table 5, by any appropriate means such than bolting and/or welding and/or embedding.
  • the walls 25 allow complete interlocking of the electromechanical actuation device 4 on the frame 2, and increased stiffening of the latter compared to the embodiment of the figures 1 to 3 .
  • the walls 25 are shaped to fit together on their longitudinal edges, which makes it possible to eliminate or in any case considerably reduce any effects of twisting of the work table 5 with respect to the base 23 during the operating cycles of the press 1, and also reduce vibrations considerably.
  • this second embodiment with partitioning walls and stiffening 25 advantageously makes it possible to double the natural resonance frequency of the press compared to the embodiment of the figures 1 to 3 , while reducing displacements on the ground during operation by a factor greater than 10.
  • the walls 25 are additionally coated or else incorporate in a sheet metal structure in the form of a sandwich a layer of sound-insulating and anti-vibration facing.
  • a facing may consist of any suitable fire-retardant insulation, in particular based on compacted natural and/or synthetic fibers or even thermoformed synthetic foams. This improves the safety and comfort of operators on production sites by increased absorption of noise pollution from the operation of the press.
  • the electromechanical actuation device 4 is mounted on the frame 2 in an intermediate position between the plate 23 of the base and the table 5, therefore in a central position in the plane of movement of the forming device 3 and ideally on the axis V of the forming tool, located under the work plane P1.
  • the forming device 3 is coupled to the actuating device in such a way that the forming tool 35 is maintained in all positions in or above the work plane P1 of the work table 5.
  • the electromechanical actuation device 4 comprises an electric motor 41 of the Torque type, integrally mounted and movable in translation along the pillars 21 of the frame 2 by means of a carriage 45 on rails or slides 7 fixed in internal reservations of the pillars 21.
  • the carriage 45 and the slideways 7 thus form complementary members for linear guidance of the actuating device 4 on the frame 2.
  • the electromechanical actuating device 4 is furthermore arranged in kinematic connection with a set linear displacement motor 6 in translation along a central vertical axis V contained in the plane P2 with respect to the work table 5.
  • the electromechanical actuation device 4 is thus adjustable in height in the plane P2.
  • the motor assembly 6 is advantageously arranged on the plate 23 of the base of the frame 2 and fixed to the latter by any suitable means, as well as to the casing 42 of the motor 41 of the actuation device 4.
  • the motor assembly 6 comprises a worm screw 61 mounted freely in rotation along the axis V on the plate 23 in a central orifice thereof.
  • the endless screw 61 comprises a lower section 611 forming a drive shaft integral with a motor flywheel 62 mounted coaxially on the drive shaft.
  • the endless screw 61 also comprises a threaded upper section 612 extending in the extension of the lower section 611 along the axis V through a bell 63 for pressing the engine flywheel 62 into the orifice 231 of the plate 23 to avoid any translation of the screw 61 along the axis V, and into a blind bore along the axis V of internal diameter substantially equal to the external diameter of the threaded section of the screw 61.
  • the screw 61 is coupled to the motor by its threaded portion via a nut 64 fixed on the casing 42 of the motor 41 coaxially to said blind bore.
  • a rotation of the steering wheel 62 in one direction causes the screw 61 to rotate in the same direction on itself, which by grip effect in the nut 64 induces a vertical translation of the actuating device 4 guided by its carriage 45 on the slides 7 of the frame 2 upwards or downwards.
  • a rotation of the steering wheel 62 in the opposite direction then induces a corollary vertical translation in the opposite direction of the actuating device 4.
  • the flywheel 62 can advantageously be controlled by a mechanical, electronic and/or hydraulic drive system, according to standard techniques in the field of industrial automation.
  • this actuation is electro-controlled by central numerical control for piloting the assembly of the press and of the electric motor 41 as described in more detail below.
  • the electric motor 41 of the electromechanical actuation device is a Torque type motor.
  • a Torque type motor has the advantage of being able to be actuated and driven essentially by an electronic setpoint signal in a substantially instantaneous manner, that is to say without inertia. It is therefore possible to reach a desired operating speed very quickly, or to instantly stop the rotation of the motor and therefore of the forming device 3 which is associated with it. It is also possible to adjust the motor control setpoint in such a way as to optimize the electronic consumption of the motor. It is thus possible to adjust the operating control of the motor to the particular kinematics of the forming device 3 according to the needs.
  • This type of motor is also fully electronically controllable, if necessary with variations in speed and power/torque during the cycle depending on the workpieces.
  • the Torque motor makes it possible to vibrate the forming device during the cycle, if necessary with adjustable pitch, to improve the surface conditions of stamped parts for example. It is thus possible to initiate stamping cycles of parts incorporating vibrations of the forming device 3, which is not permitted by any other type of electromechanical press to date, in addition by providing a possibility of adjusting the frequencies and amplitudes of vibes.
  • the motor 41 preferably comprises two eccentric shafts 43d, 43g mounted on bearings to each of which is coupled by a first ball joint (or any similar coupling) a first end of a connecting rod 44d, 44g whose second end is mounted by a second ball joint (or any similar coupling) on the forming device 3.
  • the two eccentric axes 43d, 43g are such that they are exactly symmetrical to each other with respect to the planes medians P2, P3 of the press 1.
  • the slightest axial offset of the eccentrics with respect to these two planes can be critical to the operation of the press, in particular to the regular guiding of the forming device as well as to the integrity of the motor 41.
  • Torque motor 41 also has the advantage of offering great versatility of configuration to the actuation device 4, in particular for varying its power. It is in particular possible to associate in series a plurality of Torques 41 motors and to couple them axially in order to double the power of the press.
  • the forming device 3 is mounted movable in translation in the vertical plane P2 on or relative to said worktable 5. It advantageously comprises a gantry sliding by slideways 8 on said table 5, said gantry comprising a crosspiece of a forming tool 35 by means of a tool holder 34, said crosspiece being secured at its respective ends, for example by welding or bolting, to a first end of a connecting arm 32d, 32g mounted rotating at a second end by a shaft 36d, 36g to one of said connecting rods 44d, 44g of the electromechanical actuation device 4 via a said second ball joint traversed by said axis 36d, 36g according to conventional methods for those skilled in the art.
  • the forming device 3 is thus driven in translation on the table 5 in the plane P2 by a conventional connecting rod-crank system in the field of machining presses.
  • the slides 8 are preferably arranged on the arms 32d, 32g of the sliding gantry on the one hand and in lateral openings 51 for guiding said arms formed for this purpose in the table 5 symmetrically to the plane P2.
  • means for moving and dynamically adjusting the distance movable crosspiece 31-worktable 5 are provided on the forming device for adjusting the bottom dead center and the absolute rule located at the level of the table as well as a compensating for expansion during use of the press.
  • the press 1 of the invention also advantageously comprises a digital control device, not shown in the figures.
  • This digital control device well known per se to those skilled in the art in the field of machine tools and industrial automation, is preferably configured as a priority to electronically control the actuating device 4 according to work cycles desired and pre-programmed into the CNC or loaded into it via a company network.
  • the numerical control can thus in particular carry out the continuous adjustment of the parameters of supply and speed of rotation of the Torque motor 41 to deliver a determined power from the press.
  • the digital control can also advantageously drive the linear displacement motor assembly 6 before adjusting the height of the Torque motor 41 on the frame 2 and thus the striking height of the forming tool 35 with respect to the plane P1 of the table of work 5 as needed.
  • the numerical control can also be associated with auxiliary automatons for loading the press 1 and for changing the forming tool 35 on the tool holder 35.
  • a sample means any part or piece of metal raw material to be formed or preformed part to be reworked.
  • the location of the electromechanical actuation device under the work table 5 provides the press with increased compactness and stability.
  • the use of a Torque motor provides the advantage of essentially electronic instantaneous motor control, which makes it possible to optimize the electrical consumption of the motor according to the work carried out.
  • the press structure proposed a horizontal press, in which the frame 2 is pivoted by 90° as well as the actuation device 4 and the forming device 3.
  • the vertical orientation of the motor torque 41 does not disturb its operation and the linear guide by slides of the forming device 3 on the work table 5 ensures in any event, with adequate lubrication, good performance of the press even in an inclined position.
