Definitions

  • the present disclosure relates to a mechanical contact device comprising a base, a movable support adapted to move on the base in a direction X and a contact member carried by the support.
  • the mechanical contact device can be any device, equipping a machine or an apparatus, and intended to have a working position in which it comes into contact with a workpiece or a tool and to be animated by rapid movements , for example during maintenance or adjustment of the machine or the device.
  • the contact member within the meaning of the present disclosure may for example be a tool holder, for example for a drilling or machining tool, equipping a machine or a robot, or even a setting or recovery finger of effort for a workpiece to undergo treatment in a machine.
  • the contact member may be a rear stop finger of a press brake.
  • the patent application European No 1 264 647 discloses a sheet metal press brake equipped with a mechanical contact device formed by a rear stop device comprising a contact member formed by a stop finger.
  • This press brake comprises a frame having on the front side a vertically movable upper apron and a lower plywood deck.
  • a sheet to be folded is disposed in the space between the aprons, the rear edge of this sheet abutting against the contact member of the rear stop device to ensure its correct positioning during folding.
  • the upper apron is moved down and the tools it carries perform the folding in cooperation with the matrix that carries the lower deck.
  • the rates of use of the press brakes are high and the operations of setting up the sheets and adjusting the position of the different components of the press brake must be performed quickly.
  • a part of the body of the operator in particular his hands, can be in the space between the upper and lower aprons or in the immediate vicinity of one of these aprons, in particular the apron inferior.
  • the entire rear stop device is moved back. At the end of such an operation, this assembly is advanced rapidly forward so that the contact member comes into its working position, in which it performs its function of backstop.
  • one or more rear stop devices of the aforementioned type are mounted on a main carriage which, after an adjustment or repositioning operation, quickly advance this device or devices forward.
  • the advance movement is effected in two stages, ie a first rapid phase from the extreme backward position to an intermediate position, then a final stage of advancement which, in the zone in which it is likely to strike a part of the body of the operator, operates slowly.
  • this hampers the production rates since, overall, the speed of movement of the contact device is affected.
  • a mechanical contact device which makes it possible to limit or even avoid the risk of injury to a person or material damage, if a part of a person's body or an object were to be struck by the contact member during an operation or maneuver such as, for example, a adjusting or repositioning a machine or apparatus equipped with the contact device, while substantially overcoming the aforementioned drawbacks.
  • the direction X is a horizontal direction of forward-backward motion
  • the Y direction is the vertical direction
  • the Z direction is a horizontal direction of right-left movement. This is particularly the case when the mechanical contact device is a rear stop device of a press brake.
  • the contact member plays its role of mechanical contact, for example a back press brake. Indeed, in this case, the displacement of the mobile support under the effect of a thrust force (towards the rear) exerted in the direction X is restricted, so that the contact member can cooperate by static contact with a piece, for example the rear edge of a sheet to be folded.
  • the device defined above does not affect or virtually the normal speed of movement of the contact member and, therefore, does not affect or almost no rate of the machine, for example a press- folder, which is equipped with the mechanical contact device.
  • the device comprises two reaction members disposed substantially symmetrically on either side of a plane of symmetry, and the locking arm has two reaction zones which, when the lever is in its rest position, are arranged substantially symmetrically on either side of said plane of symmetry, said plane of symmetry being parallel to the X and Y directions and being defined when the lever is in its rest position.
  • this arrangement makes it possible to obtain the same effect during an impact due to a relative displacement between the contact member and an object or the body of a person in the direction Z, in one direction or in the other that is to say, when the Z direction is a right-left horizontal direction, either to the right or to the left.
  • the retaining means are able to be controlled between a holding situation in which they are active and oppose the pivoting of the lever, and the release situation in which they are deactivated.
  • the retaining means are not permanently effective.
  • the retaining means can be controlled in the holding situation when the machine equipped with the mechanical contact device is in operation, for example during folding operations performed in a press brake, and be controlled in the release situation. during machine setting operations prior to or following operation, in particular of the type requiring intervention by an operator.
  • the retaining means can be controlled by an electronic control unit.
  • reaction surface is at least partly convex.
  • the lever axis is carried by the movable support and said at least one reaction member is integral with the base.
  • the retaining means comprise a first retaining member integral with the base and a second retaining member carried by the lever.
  • one of the first and second retaining members comprises a member selected from a latch, a permanent magnet, an electromagnet and a suction cup, while the other of the first and second retaining members comprises a retaining surface adapted to cooperate with said element.
  • the retaining means may also comprise other means, for example a weight carried by the lever or integral with it to naturally recall the lever in its rest position under the effect of gravity.
  • This weight can be directly integrated in the lever, for example being formed by a secondary arm, making a angle with the locking arm and having a mass sufficient to return the lever to the rest position. It can also be formed on the locking arm or on another part of the lever, provided that it tends to return it to its rest position.
  • Such a weight may form the second retaining member mentioned above.
  • the base may have an abutment surface against which a portion of the lever abuts during its return by the weight under the effect of gravity.
  • the retaining means may exert permanent retention, for example when one of the first and second retaining members comprises a permanent magnet or a permanent latch that can be unlocked by a force opposing a permanent elastic return in locked situation.
  • the retaining means are naturally active and are deactivated during an impact on the contact member, whose intensity exceeds the retaining force exerted by said retaining means.
  • the retaining means may be of the controllable type between the restraint situation and the release situation. This is for example the case when one of the first and second retaining members comprises a controlled lock, an electromagnet or a suction cup.
  • the retaining means are activated in the retaining situation, for example during folding operations performed in a press brake, and can be deactivated in the release situation, to allow adjustments of the hair press.
  • the lever carries a locking stop, permanently recalled in an inactive position and suitable, during a shock on the contact member causing a pivoting of the lever while the retaining means are active, to adopt an active position in which said pivoting of the lever is limited by a contact between said stopper and a fixed abutment of the movable support.
  • such a shock may be due to the sudden introduction of a sheet to be folded in the press brake. If the setting up of the sheet caused such a shock on the contact member, then that a bending operation begins, this shock could, if its intensity is very strong, unintentionally release the movement of the lever, exceeding the retaining force exerted by the yet active holding means, thus ensuring that the contact member also moves and so out of its desired working position.
  • the aforementioned blocking abutment avoids this since, during such an impact on the contact member, the movable support moves and causes the beginning of pivoting of the lever.
  • the blocking stop then in its active position, then prevents the lever from pivoting further through the contact between this blocking stop and the abutment surface integral with the movable support, before the restraint operated by the retaining means ceases to to be effective.
  • the lever is thus stopped in a position that is only very slightly rotated, and this restraint, combined with the cooperation between the reaction member secured to the base and the reaction zone of the locking arm, stops the movement of the mobile support relative to the base as long as the retaining means remain active.
  • the contact member does not move more than the short stroke that caused the slight pivoting of the lever.
  • a shock causes an intense effort that stops immediately.
  • the contact between the stopper and the abutment occurs before this effort overcomes the restraining force exerted by the active restraining means. Only if a significant effort is applied sustainably, as in the case where an object is hit by the contact member on the move and would form an obstacle on its course that, depending on its intensity, this effort can overcome the force of restraint exercised by the active restraining means. If this retaining force is exceeded, the retaining means are then deactivated, which allows the locking stop to return to its inactive position, so that the pivoting of the lever is released, which allows the displacement of the organ of contact.
  • the blocking stop is useful both when the retaining means are of permanent type (for example with flyweight, latch or permanent magnet) by exerting an exerting retaining force, than when the retaining means are of controllable type. enter here retaining situation and the release situation, and are for example constituted by a controllable lock, an electromagnet or a suction cup.
  • the device comprises a stop actuator adapted, during an impact on the contact member, to cooperate with the locking stop to urge the latter in its active position.
  • the stop actuator is secured to the second retaining member.
  • the stop actuator is adapted to cooperate with the stopper via at least one ramp that has one of the elements comprising the stop actuator and the stopper.
  • the displacement of the movable abutment under the effect of the shock is thus facilitated and can operate in a direction different from that of the force exerted on it by the thrust actuator.
  • the device comprises means for biasing the lever in the rest position while the locking stop is in contact with the abutment and the retaining means are in the retaining situation.
  • a shock may cause a slight pivoting of the lever, but it remains blocked by the contact between the locking stop and the abutment. As soon as this shock produces an instantaneous force, the intensity of which disappears after the impact, the retaining means remain in restraint. In this case, the lever is recalled in a rest situation and the slight displacement of the contact member that occurred during the shock is canceled.
  • the second retaining member is able to move relative to a reaction part of the lever which is rigidly connected to the locking arm, the stop actuator is rigidly connected to the second retaining member, and one of the elements comprising the stop actuator and the second retaining member cooperating with said reaction part via an elastic return means.
  • said reaction portion is formed on a secondary arm of the lever, the second retaining member and the actuator are disposed on either side of the secondary arm, and a return spring is interposed between the secondary arm and the one of the elements formed by the thrust actuator and the second retaining member.
  • the present disclosure also relates to a sheet metal press brake comprising a mechanical contact device of the type described above, forming a backstop device of the press brake, the press brake further comprising a frame having a front side upper apron movable vertically, substantially perpendicular to the X and Z directions, and a lower plywood deck, the base being carried by a main carriage, movable back and forth in the direction X, preferably via a rail system allowing a sliding of the base relative to the main carriage in direction Z.
  • FIG. 1 On the figure 1 is schematically shown a side cheek of a frame 1 of a press brake, the cheek is shaped like a gooseneck and having on the front side a fixed lower deck 2 whose upper face serves as a support for a folding die 3
  • the press brake also comprises an upper apron 4 movable vertically back and forth in the direction Y and carrying at its lower end a folding tool 5 cooperating with the die 3 to, when a sheet 6 is disposed in the press brake, make a folding of this sheet.
  • the press brake comprises a rear stop device 10 comprising a base 12, a movable support 14 adapted to move on the base 12 in a front-rear horizontal direction X and a contact member 16, carried by the mobile support 14 and forming in this case a backstop finger of the press brake.
  • the contact member is carried by the support via a spacer 18 fixed to the movable support via a pivot axis 19 extending in a horizontal right-left direction Z which, under certain circumstances, allows the spacer and the contact member to rise by pivoting.
  • the contact member 16 is therefore disposed at the front of the spacer 18.
  • the rear stop device comprises in this case also a rear wedge 17 carried by the support 14 at its rear end.
  • the base 12 is carried by a main carriage 20 which is movable back and forth in the direction X, for example via a worm drive system 22.

  • This axis is embodied by a journal 30 '(see figure 4 ), which is fixed to the base 12 and which passes through an oblong opening 32 of the support 14 so as not to hinder the sliding of the latter in the direction X relative to the base.
  • the device comprises a lever 34 which is pivotally mounted about a lever axis 36 which, in the example shown, is carried by the mobile support 14.
  • This lever has a locking arm 38 which is pivotally mounted about the lever axis 36.
  • figure 4 shows the lever at rest, while the figure 5 shows the lever in a rotated position about the axis 36.
  • the device comprises retaining means which, on the figure 4 , are active in a restraint situation and oppose the pivoting of the lever which is thus maintained in its rest position and which, on the figure 5 , are inactivated in a release situation in which the lever can be rotated.
  • these retaining means comprise an electromagnet 40 which forms a first retaining member secured to the base 12.
  • the lever comprises a second retaining member 42 which, in this case, is carried by a secondary arm 44 of the lever arranged so that, with the locking arm 38, it substantially forms an L, the locking arm forming in this case the small branch of L and being oriented downwards.
  • the second retaining element 42 has a surface made of a material sensitive to magnetic attraction, to be held against the electromagnet 40 when the latter is activated.
  • the electromagnet could be replaced by a pneumatic sucker, in which case the surface of the second retaining member located opposite the suction cup could be a solid surface (the tapping 46 visible on the Figures 4 and 5 , which will be described later, which may not be traversing).

  • the retaining means may comprise a flyweight, a permanent magnet, or a permanent latch whose bolt could, however, retract if a large force is exerted on the lever, for example if the lever moves and hits a part or a body part of a person such as an operator.
  • the cooperation between the bolt and the strike could be via a ramp tending to recall the bolt in the retracted position during a movement between the striker and the bolt, against a permanent elastic return bolt protruding position , the stiffness of the elastic return being determined to allow the retraction of the bolt only from a given intensity of the efforts between the striker and the bolt.
  • the figure 4 shows the retaining means in the retaining situation, and it can be seen in this figure that the lever 34 is in its rest position, in which the locking arm 38 faces reaction members (hereinafter described) provided in a recess 13 of the base in which the locking arm protrudes in this rest position.
  • the locking arm 38 of the lever cooperated with the reaction members to allow that the lever is raised, thus escaping the walls of the recess 13, and thus allowing the support 14 and the contact member 16 (and also the spacer 18) to move by pivoting about the axis 30 .
  • the lever is returned to a position in which its secondary arm 44 is lowered. This return is made by gravity, under the effect of the weight of the arm 44, the lever being housed in a through window 35 of the support 14.
