Definitions
- the present invention relates to a pre-crimping and crimping the edge of a sheet which is supported by a fixed die, according to the preamble of claim 1.
- 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 folded 90 ° from the rest sheet metal.
- the crimping operation consists, in a first step, in folding it down partially - generally at an angle of 45 ° - towards the other sheet.
- the crimping proper 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 it.
- This kind of operation is traditionally done in press, on the table open with hydraulic movable matrix, or on fixed matrix using trolleys tilting blade holder.
- an objective of the invention is to control the movement of the tools, while minimizing parasitic forces, and thus improving the quality and consistency of the setting.
- Another objective of the invention is to propose a unit of pre-crimping and crimping of simple design, of a low cost price, simple to implement and maintain while working at high speed.
- the unit includes two movable heads, one for pre-crimping and the other of crimping, which are moved synchronously to come one after the other press the edge of the sheet and release it.
- EP-A-0 592 848 the synchronized movement of the two heads is controlled by a pneumatic cylinder or, alternatively, by a servomotor via a screw-nut system.
- the unit described in EP-A-0 592 848 has a crimping 24 which is mounted in the upper part of a vertical oscillating arm 38 of which the lower end carries a first pin 138 by which it is articulated on a rod 136 which can pivot freely around a fixed axis 142.
- this arm 38 carries a second pin 138, by which it is articulated on a another link 136 also pivotally mounted around a fixed axis 142.
- the second pin 138, as well as the link 136, are positioned on the outer edge of the lever, in an area far removed from the matrix and edge of the sheet to be worked (see figure 8).
- the crimping head describes a curvilinear trajectory, but the radius of this trajectory is relatively large relative to the width of the edge of the sheet.
- the crimping head describes a practically straight trajectory, of direction vertical, during the actual pressing phase, during which it is in contact with the sheet.
- the trajectory is only truly curvilinear during the approach phase.
- the unit according to the invention is intended for pre-crimping and crimping the edge of a sheet whose plane is substantially horizontal, which is supported by a fixed matrix. It includes two movable heads, one for pre-crimping and the other for crimping, which are moved in synchronism to come one after the other press the edge of the sheet and release it, and the crimping head describes, during pressing, a curvilinear trajectory, the tangent at the end of crimping is substantially orthogonal to the plane of the sheet, its face active remaining substantially parallel to itself during this displacement, this crimping head being mounted in the upper part of a swing arm approximately vertical, the lower end of which carries a first pin by which it is articulated on a rod being able to pivot freely around an axis fixed, while its middle portion carries a second pin.
- this second journal is located below and substantially in line with the active face of the crimping head and is articulated on a control lever, the latter itself being articulated to one of its two ends on said second pin, at the other end on a rod - called end - can pivot freely around a fixed axis, and in the middle part on a rod - called central - can also pivot freely around a fixed axis, so that the curvilinear path described by the crimping head at during pressing has an instantaneous center of rotation located in the area where finds the bending angle of the sheet.
- This particular movement of the crimping tool allows you to work with a regular and controlled quality, avoiding the formation of a ripple on the outer panel of the sheet, matrix side.
- the movement of the presetting head is done during pressing - and in particular at the end of pressing - in an orthogonal or substantially orthogonal direction in terms of the sheet.
- the two heads are driven by a common drive shaft.
- the shaft drive the unit according to the invention always turns in the same direction. His movement is transmitted to the heads via a mechanism to eccentric.
- the pre-crimping and crimping cycle corresponds to one revolution complete of the motor shaft, and the stop precision at the end of the cycle did not of importance, any interference between the transmission mechanisms of movement and moving heads being avoided.
- the motor shaft is rotated by a motor electric with incorporated speed reducer (gearmotor).
- gearmotor a motor electric with incorporated speed reducer
- the presetting head is carried by an oscillating arm, approximately vertical, the lower end of which carries a first pin by which it is articulated on a rod being able to pivot freely around an axis fixed, while its upper part carries a second pin hinged on a control lever.
- the plane of the sheet being substantially horizontal and the arms carrying the presetting and crimping heads being both approximately vertical, the crimping head is located below the pre-pressing.
- the subject of the invention is also a pre-setting assembly and crimping tool for sheet metal, and in particular for very long sheet metal, this set being composed of several juxtaposed units such as that described above.
- At least some of said units have a positioning angular offset from that of the others, the arrangement being such that the directions at the end of the travel of the different pre-crimping and crimping heads are in all zones substantially orthogonal to the surface of the sheet.
- the part 1 is supported by a fixed matrix 14 whose support plane 15 is horizontal.
- This horizontal support plan will be conventionally called in the rest of the description and in the claims "sheet plan".
- the lower sheet, which rests on the matrix 14 has a width greater than that of the other sheet 12; she presents a flange 11 folded at right angles to the rest of the sheet, and therefore disposed vertically.
- the initial folding of the flange 11 was carried out using a separate tool, by example in press. It is this rim 11 which must be folded back against the border zone 13 of the other sheet 12 to perform the assembly by crimping the two sheets.
- the pre-crimping tool comprises a head 2 having a working face - or active face - flat 20, carried by a moving part formed by an arm 22 and a upper intermediate part 21.
- the arm 22 stands in a position close to the vertical, slightly tilted outwards from this vertical direction.
- the arm 21 carries a first pin 24, by which it is articulated to a link 4 articulated on a fixed axis 40, that is to say carried by the frame of the unit (not shown in Figures 1 to 4).
- Part 21 carries a second pin 23 by which it is articulated on a control lever 5, of approximately shape triangular.
- the latter pivots freely around a fixed axis 50, and carries a journal 51 by which it is articulated on a control rod 52.
- the rod 52 is curved, and its opposite end carries a pin 53 by which it is connected to the eccentric and connecting rod control, which will be described later.
- Trunnion 53 is subjected to a back and forth movement along a circular arc path, with center 530.
- the low 4 and high 52 links are arranged towards the outside (relative to the matrix 14).
- the points corresponding to axes 23, 50, 40 and 24 constitute the angles of a quadrilateral fictitious deformable of which one side is materialized by the part 21, 22 carrying the head 2.
- the different axes are positioned, and the lever arms chosen, such so that the movement of the active face 20 during the operation is done according to a substantially vertical direction, perpendicular to the plane 15.
- This face 20 is in a plane inclined at 45 ° relative to the plane 15, when it is at the end of the working stroke ( Figure 2).
- the preserting operation results from the upward movement of the pin 53 around the point 530 (arrow I 1 , FIG. 2), which causes the lever 5 to tilt downwards, around the point 50 (arrow I 2 ), and the deformation of the quadrilateral mentioned above.
- the lines L1 and L2 which respectively connect the points 23 and 50 on the one hand, and 24 and 40 on the other hand, are both parallel to the bearing face 15 (sheet metal plane), c 'that is to say horizontal ( Figure 2).
- the flange 11 once folded at 45 °, is referenced 11 '.
- FIG. 5A illustrates a presetting operation using a working head similar to that which has just been described, but whose working direction is not perpendicular to the plane of the sheet.
- This direction symbolized by the arrow E , is oblique to the vertical, and breaks down into a vertical direction E 1 (orthogonal to the sheet metal plane) and horizontal E 2 (tangent to the sheet metal plane).
- the component E 2 has a parasitic effect, since it tends to excessively wind the rim 11 during its folding, the amplitude of the total winding being referenced i in FIG. 5A.
- the displacement of the head 2 takes place on the contrary in a purely vertical direction, perpendicular to the plane of the sheet, which reduces the amplitude of winding, the latter corresponding to a value j very substantially less than i .
- the crimping tool shown schematically in Figures 3 and 4 comprises a working head 3 which is carried by an arm 31 approximately vertical and has an active lower face - working face - 30 whose function is to press the partially folded edge 11 'to fold it completely and bring it in contact with the edge zone 13 of the sheet 12, so as to ensure complete crimping from room 1.
- the arm 31 has, on the inner side, a middle portion 32 lying in overhang below the active face 30, substantially perpendicular to the latter.
- the arm 31 is provided at its lower end with a first pin 33, by which it is articulated on a link 6 which can pivot freely around a fixed axis 60.
- Part 32 carries a second pin 34 by which it is articulated the end of a lever 7. It is a slightly bent lever, the opposite end (outer side) carries a pin 70.
- the latter is articulated on two rods 73, 74.
- the rod 73 approximately horizontal, can pivot freely around a fixed axis 730.
- the rod - or tie rod - 74 approximately vertical, extends upwards, and its opposite end (upper end) carries a pin 75.
- Trunnion 75 can follow a back-and-forth trajectory in an arc around the point 530 already mentioned with reference to Figures 1 and 2.
- the lever 7 In its central (angled) zone, the lever 7 carries a pivot 71 hinged on a link 72 able to pivot freely around a fixed axis 720.
- the lever 7 and the link 6 are approximately horizontal, directed towards outside.
- the rod 72 extends downward (relative to the lever 7), and it has a approximately vertical direction.
- the crimping tool 3 describes a complex movement, the trajectory of which is imposed by the semi-circular trajectories pins 70, 71 and 33 around axes 730, 720 and 60 respectively.
- the pin 75 is in the low position, which has the effect to keep the head 3 tilted outwards, free with respect to the part 1 (figure 3).
- this mechanism is arranged, and the various lever arms determined, so that the active face 30 follows, as soon as it comes into contact with the sheet edge 11 ', a trajectory curvilinear whose established center of rotation (in mobile position) is very close to the area folding (top of the folding angle) of the sheet, this face 30 moving further parallel to itself from the moment it came into contact with the sheet, until the end of crimping.
- the tangent to this trajectory is, at the end of the race, normal to the sheet metal (perpendicular to face 15).
- points 730, 70 and 71 are almost aligned; point 71 progresses slower and slower, while points 34 and 33 go down.
- the linkage produces a knee brace effect which develops an effort of very high pressing during work.
- FIG. 6A represents a crimping head the pressing direction G of which is rectilinear and oblique with respect to the plane 15 of the sheet; it breaks down into an orthogonal component G 1 and a tangential component G 2 . This generates, during the operation, a parasitic force which tends to move the part, which compromises the quality of the crimping.
- the crimping head 2 follows a curvilinear trajectory H centered at a point C (with variable position) located in the zone Z where the bending angle of prison. At the end of crimping, this trajectory is perpendicular to the surface 15.
- the crimped edge is referenced 11 ".
- the different fixed axes are carried by a frame 8, which also supports a motor shaft 90, rotated - in a single direction symbolized by the arrow R - by means of an electric geared motor 9 .
- the shaft 90 is connected, via an eccentric pin, to the axis 910 of a connecting rod 91.
- the opposite end of the latter carries a journal 92 by which it is articulated to a spreader 93. This is pivotally mounted around the fixed axis 530 already mentioned.
- This lifter carries the pins 53 and 75 for driving the connecting rod control 52 (of the presetting tool) and of the tie rod 74 (of actuation of the crimping), respectively.
- the lifter 93 In the cycle start position, favorable for removing the crimped part and when a new part is put in place, the lifter 93 is in a position average angular ensuring the clearances of the two heads 2 and 3 ( Figure 7).
- the lines M1 and M2 which connect, respectively, the points 34 and 71 on the one hand, and 33 and 60 on the other hand, are both parallel to the sheet metal plane 15, that is to say say horizontal (see Figure 4).
- the gearmotor and eccentric control enables the pre-crimping and crimping in one complete turn of the motor shaft. Contrary to oscillating shaft systems (such as, in particular, that described in WO-93 05902), the stop precision at end of cycle therefore no longer matters, and has no effect on the quality and precision of work.
- the journal 92 which connects the eccentric rod 91 to the lifter 93 is a frangible bar, capable of breaking (by shearing) if the effort of transmission exceeds a determined threshold. It is therefore calibrated to break if an effort exaggerated (and abnormal) is requested at the crankshaft. This is the case, for example, if a body stranger inadvertently interposed between work heads and the part to be crimped. This barrette therefore has a safety role.
- a system of eccentric play catch mounted at the pin 53 which connects the lifter to the lever 52.
- a similar system can be provided at the pin level 70 for example.
- a mark can be provided on the shaft of the gearmotor, and two marks on the frame (one for pre-setting, the other for crimping). Two reference faces are provided on the preserting mechanism, and two reference faces are provided on the crimping mechanism.
- the procedure is similar for crimping.
- the overhang of the crimping head 3 on its arm 31 is therefore reduced, and its working stroke has a relatively small amplitude, which makes it possible to develop a high compression force during the crimping operation.
- the presetting head 2 has a higher overhang on its arm 21, and its working stroke is of greater amplitude. It acts on the part with a lower pressure than the crimping head.
- Such a unit can only work over a length limited sheet metal.
- To treat a very long sheet, and in particular its entire periphery it is possible to juxtapose a set of units such as the one described above, which will be operated jointly and synchronously, to ensure crimping on a great length, for example over the entire perimeter of the sheet.
- a set of units such as the one described above, which will be operated jointly and synchronously, to ensure crimping on a great length, for example over the entire perimeter of the sheet.
- the units are adjustable mounting on a frame.
