Definitions

  • This invention is related to an impact engraving machine which includes a pneumatic or solenoid engraving device equipped with a striker point capable of impacting on the engraving surface and producing on the surface a pointed deformation on each impact.
  • the machines of the type indicated are utilized to engrave signs and/or characters of different type on surfaces of pieces of metal, of plastic material, etc., the whole set of signs and characters engraved comprising a key or identification reference or a supplier of determined information.
  • machines For the purpose of reducing the volume of the machine, machines are known in which the engraving device is mounted on a support which can be moved in controlled manner along an axis parallel to the surface to be engraved and also can turn in both directions a certain angle, also in a controlled fashion, around said axis.
  • This type of machine is usable when the surface to be engraved does not require an excessive turn of the striking point, in such a way that its incidence on the surface to be engraved is practically normal in all cases.
  • the axis over which the support of the striking device is mounted is comprised of an endless screw which crosses a threaded bore hole of the support. This endless screw will cause the linear displacement of the support toward one side or the other. Also, on the lead screw there is mounted a U shaped stirrup, the central branch of which is related to the support and with the activating motor through the gear systems. The tipping of the stirrup causes the turning one way or the other of the support, around the lead screw.
  • the axis on which the support of the engraving device is mounted consists of a bar of circular section, along which the support can be moved and on which it can turn a certain angle in both directions.
  • transmission mechanisms are required from the two motors for the linear displacement and for the turn of the support, complicating the construction and function of the whole.
  • the support of the engraving device is revolving with respect to the lead screw or bar along which the linear displacement of the device takes place.
  • French publication no. 2 459 086 shows a unit for marking siderurgical products, comprising a striking point on a carrier which can move in two octogonal directions, in a plane that is vertically parallel to the surface to be marked; another unit that allows applying pressure on said striking point on the surface of the siderurgical product; and an activating remote control for the various movements to be effected, with the transverse movement of the carrier being effected along two guides placed on a transverse beam or rod.
  • An impact engraving machine comprising a pneumatic or solenoid engraving device equiped with a striking point capable of impacting on the surface to be engraved and produce on it a point deformity on each impact, which device is mounted on a support which can be moved in controlled manner along an axis formed by a polygonal guide-bar parallel to the surface to be engraved, and may turn in both directions a certain angle, also in a controlled manner, around said axis, characterized in that it has a bridge fixed to the polygonal guide-bar which runs between the ends of said guide-bar; a longitudinal transmission mechanism composed of a belt which runs along the bridge, activated by a motor mounted on said bridge, and its belt moving, during its movement along the guide-bar, a slide found on the other side of the guide-bar with regard to the bridge, the support, which carries the engraving device, being fixed to the slide, said slide being related with the section of the belt found nearest to the guide-bar; and in that the assembly composed of the guide-bar and the bridge is related with a
  • the machine according to the invention includes a frame or structure 1 which is capped below on lugs 2 of angular support, which enables locating the machine both on flat surfaces and on curved surfaces, for their engraving.
  • the machine includes an engraving device 3 which is equipped with a striking point 4, which impacts on the surface to be engraved in order to produce point deformities on it with each impact.
  • the device 3 is mounted on a support 5 which can be moved in controlled manner along an axis 6, parallel to the surface to be engraved, and it can also turn in both directions a certain angle, also in controlled manner, around the axis 6.
  • the axis 6 is embodied in a guide-bar 7, Fig. 6, of polygonal section, which can adopt for example a section approximately rectangular, having angular longitudinal channels 8 coming from two of its opposing faces.
  • a slide 9 is mounted which partially covers the bar between the channels 8.
  • the slide 9 is the bearer of race elements which will facilitate their sliding along the bar 7.
  • the guide-bar 7 also has mounted between its ends a fixed bridge 10, Figs. 1, 4 and 5. As observed in Fig. 1, the system formed by the guide-bar 7 and the bridge 10 is mounted with the possibility of free turning between the laterals of the frame or chassis 1 of the machine, by means of bearings 11.
  • the bridge 10 has fastened on the outside two end supports 12 and 13, which are carriers of pulleys 14 between which a belt 15 runs.
  • a pulley 16 of greater diameter is mounted which is related by means of a transmission belt to the pulley 17 of smaller diameter which is solidary with the axis 18 of an activating motor 19.
  • the support 5 of the engraving device 3 has an arm 20, Figs. 4 and 5, which overhangs in the direction opposite to that occupied by the striking point 4, Fig. 1, behind the bridge 10 and comes to cross perpendicularly the stretch of the belt 15 nearest to the guide-bar 7.
  • This arm has, coming from its front surface, a transverse slot 21, Fig. 4, in which this lower section of the belt is introduced as adjusted, without possibility of their slipping from each other.
  • the belt 15 will have an internal surface transversely ribbed and the slot 21 will be limited, at least on one of its surfaces, by a gearing 22 capable of being coupled between the ribbing of the belt 15, in order to assure mutual anchorage.
  • the displacement of the belt 15 is caused by means of the motor 19, which will drag the arm 10 along the guide-bar 7, varying the direction of turn of the motor the change of direction of displacement of the support 5 is achieved and, thereby, the direction of displacement of the engraving device 3.
  • the motor 19 utilized for causing the displacement of the slide 7 and thereby the engraving device 3, is mounted on the bridge 10 set at the ends of the guide-bar 7.
  • the system formed by the guide-bar 7 and the bridge 10 is related to the tipping mechanism which is comprised of an arm 23 which is fastened perpendicularly at one of its ends to the said system, as a continuation of the bridge 10.
  • the opposite end this arm 23 is capped in a toothed sector 24, Fig. 7, on an axis coinciding with the axis of turn 6 of the guide-bar 7.
  • the toothed sector 24 engages with a pinion 25 with which a pulley 26 of greater diameter is solidary, which is related to a smaller pulley 27, solidary with the axis of an activating motor 28 which is mounted on the chassis 1 of the machine.
  • the linear displacement of the support 5 and therefore of the engraving device 3 is achieved by means of a transmission mechanism 15 and an activating motor 19 which are mounted on the bridge 10 solidary with the guide-bar 7, while the motor 28 and transmission mechanism which causes the tipping of the engraving device 3 is mounted on the chassis 1 of the machine.
  • a transmission mechanism 15 and an activating motor 19 which are mounted on the bridge 10 solidary with the guide-bar 7, while the motor 28 and transmission mechanism which causes the tipping of the engraving device 3 is mounted on the chassis 1 of the machine.
  • the system of fastening of the support 5 to the transmission belt 15 is simple and of great safety.
  • the motor 28, in turn, which will produce the tipping of the engraving device 3 is mounted on the structure of the machine and the transmission mechanism between said motor and the guide-bar 7 is comprised of a system of gears which makes it possible to achieve the maximum precision in the angle of tipping of the striking point 4.
  • the machine can be equipped with upper handles 30 which facilitate its manipulation in the portable version.
  • the system permits marking on two planes located up to 90° apart, only by increasing the arc of turn by means of the parts 24, Fig. 7.
