Definitions

  • the present invention relates to a crimping unit on the edge of a part, in particular of a sheet, which is supported by a matrix.
  • a well-known method for joining two sheets is to crimp the edge of one of them against that of the other.
  • the edge to be crimped is bent at 90 ° to the rest of the sheet metal.
  • the preserting operation consists, in a first step, called “preserting”, to fold it back partially - generally at an angle of 45 ° - towards the other sheet.
  • the actual crimping, carried out in a second step corresponds to complete folding of the sheet metal edge which comes to rest against the edge of the other by pinching.
  • This kind of operation is traditionally done in press, on the table open with movable hydraulic die, or on a fixed die using slide trolleys tilting.
  • the device which is the subject of the invention comprises a working head provided with a crimping tool which is guided in translation in a frame and is animated by a rectilinear back and forth movement in a vertical direction so as to describe successively a downward stroke, called “go”, at the end of which the tool is applied against the workpiece for crimping, and an upward stroke, called “return”, at during which it emerges and moves away from the room.
  • a crimping tool which is guided in translation in a frame and is animated by a rectilinear back and forth movement in a vertical direction so as to describe successively a downward stroke, called “go”, at the end of which the tool is applied against the workpiece for crimping, and an upward stroke, called “return”, at during which it emerges and moves away from the room.
  • a drawback of known devices, linked to their hydraulic control, is that they require the presence of a pressure generator and distribution circuits hydraulic.
  • this type of installation is relatively noisy, poses problems safety due to the high pressures used, and is subject to leaks.
  • Another drawback is that the device must be equipped position sensors to control the actuator, and in particular the reversal of its hydraulic supply between its working strokes - "outward” stroke - and clearing - "return” race -.
  • the invention proposes to solve these difficulties.
  • the training of the working head is achieved by means of an electric gear motor, the output shaft of which rotates in continuous and in one direction only, this shaft being connected to said head by means of a eccentric and connecting rod system.
  • the device is very simple.
  • the working strokes - called “outward” - and of clearance - called “return” - of the working head each correspond to rotations successive half a turn of the output shaft, the corresponding complete crimping cycle a turn from this tree.
  • the device illustrated in FIGS. 1 to 3 is a preserting device of a part 100 arranged on a fixed matrix 10, with a horizontal upper face, on which it is suitably positioned by suitable means, not shown.
  • This part 100 consists of two overlapping sheets.
  • the edge of the lower sheet extends laterally relative to the upper sheet, and is raised at right angles, forming a tongue.
  • This is intended to be folded down, against the edge of the upper sheet, for the pinch, by the crimping operation.
  • This operation is done in two successive phases, one of "pre-crimping", during which the tongue is folded down to approximately 45 °, the other of "crimping" proper, during which it is folded down completely (at 90 °).
  • the working head referenced 2
  • the working head is equipped with a tool 20 carrying out this preserting.
  • the device comprises a fixed frame 1 at the base of which is mounted an electric geared motor 3, the output shaft 30 of which is directed horizontally, parallel to the edge of the part 100 to be crimped. This direction is perpendicular to the plane of FIGS. 1 and 2.
  • the geared motor 3 rotates the shaft 30 continuously and at uniform speed, in a determined direction of rotation, illustrated by the arrow F in FIGS. 1 and 2.
  • the (fixed) axis of the rotary shaft 30 is referenced X.
  • the drive shaft 30 is integral, both in axial translation and in rotation, with an eccentric disk 4, the axis Y of which is parallel, but offset, relative to the axis X.
  • this Y axis therefore describes a rotation about the X axis.
  • a connecting rod 5 rising upwards according to a approximately vertical direction. Its upper end is also articulated, around a journal 50 which is carried by a part 6 mounted at the base of the head 2, and integral with the latter.
  • the axis Z of the journal 50 is transverse, parallel to the axes X and Y.
  • Part 6 consists of a slide guided in translation in direction vertical in the frame 1. More precisely, as illustrated in particular in FIG. 3, the frame 1 comprises two parallel vertical plates 12 joined by a cross member 11, the outside of which are fixed a pair of vertical slides 60. In the mode of illustrated embodiment, the slides 60 cooperate with ball or roller skates 61 provided on slide 6.
  • the tool 20 is therefore movable in a vertical plane, perpendicular to that of the upper face of the matrix 10.
  • the tool 20 is provided with a blank holder, of known type, comprising a plate presser 70. This is also movable in a vertical plane, parallel to the plane tool movement; it is biased elastically downwards by one or more springs 71.
  • the height positioning of the blank holder is such that the press plate 70 comes to rest against the edge of the part just before the start of the operation crimping, in order to immobilize it properly during the operation.
  • the state illustrated in Figure 1 corresponds to the release position maximum of the tool 20 relative to the part 100. It is raised to the maximum.
  • the device is arranged in such a way that the eccentric 4 is then in neutral "high", the Y axis being above and plumb with the X axis.
  • the Z axis is in the same vertical plane as the X and Y axes.
  • the positioning of the tool, the value of the eccentricity of the disc 4 - that is to say the offset between the two axes X and Y -, and the dimensioning of the assembly are such that when the eccentric finds at its "bottom” dead center (position in FIG. 2) the tool 20 is at the end of the pre-setting stroke.
  • the "go" stroke of the head 2 which corresponds to a vertical translation, from top to bottom, of the slide 6 on the slides 60, therefore results from a U-turn of the Y axis around the X axis , in direction F.
  • the connecting rod 5 oscillates slightly on the pin 50, around the axis Z.
  • the tool During its descent, the tool has a variable speed, first accelerated, approximately constant, then decelerated, to cancel out at the end of the pre-pressing.
  • the next half-turn of the eccentric, according to F causes the working head 2 to be raised relative to the part, in a vertical rectilinear movement.
  • the spring 71 relaxes, the pressing plate 70 remaining in contact with the workpiece for some time after the tool is released.
  • the part After pre-crimping, the part is transferred to a crimping device.
  • the device which has just been described makes it possible to crimp a piece by outside.
  • the matrix 10 has a concave edge 13, the shape of which corresponds to that of the edge of the piece 100, edge which can correspond to an opening closed or semi-closed crossing the room.
  • the space available inside this opening is generally very limited, the device is arranged so that only the head 2, which has been given a appropriate conformation, crosses it.
  • the slide 6 and the frame 1 are arranged at a level below that of the matrix, the slides 60 and a large part of the frame 1 being positioned outwards.
  • the operation of the device is identical to that of the first mode of production.
