- These means 3 are synchronized with respect to the movements of the tool holder 2 with respect to the sole 1, so that a portion of strip 4 corresponding to a terminal 11 is fed between the cavities 5, 7 when they are spaced apart.
- the terminal 11 in place on the crimping station 5 7 is cut from the strip 4 and crimped at the end of the wire.
- Each die 8 is formed of an associated vertical plate and carried by the same block 16 supporting the die (s), and the tool holder 2 comprises a housing for receiving a block 16 supporting the die (s).
- the block 16 supporting the matrix (s) is generally parallelepiped, like the reception housing.
- Each anvil 6 is carried by the same block 19 anvil support (s) and the sole 1 defines a base 20 for receiving such a block 19 anvil support (s).
- the block 16 supporting the matrix (s) and the block 19 supporting the anvil (s), forming the same set of crimping tools for crimping a lug model, that is to say carrying first indentations 5 and second indentations 7 for crimping conjugated shapes, are associated with each other in an autonomous assembly, adapted so that these blocks 16, 19 can be assembled and disassembled together with respect to the device, that is to say say respectively with respect to the tool holder 2 and with respect to the sole 1.
- the block 16 support for the die (s) and the block 19 support for the anvil (s) are associated one with the another by two assembly columns 22 extending parallel to the direction of translation of the tool holder 2, that is to say vertically.
- the assembly columns 22 are engaged in corresponding bores made in the anvil support block 19 so as to be rigidly fixed to this block 19, at least when the latter is fixed and mounted on the base. 20 of the sole 1.
- the block 16 supporting the matrix (s) also comprises a vertical through hole for its guidance relative to each column 22.
- the anvil support block 19 is assembled and removably fixed to the base 20 of the sole 1 by a dovetail type assembly, with an axis parallel to the crimping axis 9, which allows positioning, relative to the sole 1, each anvil 6 and each die 8 in the vertical plane containing the crimping axis and the vertical axis of translation of the tool holder 2.
- the automatic means 3 for supplying the terminals 11 comprise a preset cassette 25 for guiding the strip 4 of the terminals.
- This cassette 25 comprises a cassette body 26 and means 67, 72, 75 for receiving and guiding the strip 4 of lugs with respect to the cassette body 26.
- the means 67, 72, 75 for receiving and guiding the strip 4 of lugs are adapted so that the strip 4 of lugs engaged in these means 67, 72, 75 is integral with the cassette 25.
- the cassette 25 constitutes an autonomous mechanism capable of receiving and guiding a strip 4 of lugs, and which can be assembly and disassembly, in a single block, independently and completely of the crimping.
- This cassette 25 can be fixed, in a single block, rigidly removable with respect to the sole 1 by fastening means for instant mounting and dismounting without tools comprising a receiving housing 30, integral with the sole 1, intended to receive cassette 25.
- the receiving housing 30 is carried by an assembly 31 for driving the strip 4 of lugs, and this drive assembly 31 is fixed to the sole 1.
- the strip 4 of lugs is, in the embodiment shown, formed of a pilot strip 13 and of lugs 11 extending perpendicular to the pilot strip 13, on one of its sides, the different lugs 11 being parallel to one another. others, regularly spaced along the pilot strip 13.
- a strip 4 of terminals For the supply of each terminal 11 in the crimping station, such a strip 4 of terminals must be moved parallel to the pilot strip 13, that is to say perpendicularly to the lugs 11 and to the crimping pin 9.
- the direction of movement 14 of such a strip 4 of lugs for the automatic supply of the lugs 11 to the crimping station is a horizontal direction perpendicular to the crimping axis 9 and to the lugs 11.
- the drive assembly 31 is therefore adapted to drive the strip 4 of lugs, and to move it, successively at each cycle, in the direction of movement 14 by a distance suitable for the establishment of a new terminal lia crimp between the crimping imprints 5, 7.
- This drive assembly 31 (FIGS. 12 and 13) comprises a first support piece 32 fixed to the sole 1 and carrying the body 33 of a jack 34 whose actuating rod 35 is parallel to the direction of movement 14.
- This actuating rod 35 carries at its free end a slide 36 guided in translation relative to the first support part 32 (which is provided with a light for this purpose) and relative to the sole 1 horizontally in the direction of displacement 14.
- This slider 36 itself carries a pusher 37 articulated to this slider 36 about a horizontal articulation axis 38 orthogonal to the direction of movement 14 and to the direction of the actuating rod 35 of the jack 34.
- the pusher 37 has a free end 39 facing forward and upwards and away from the slide 36 upwards by a compression spring 40 interposed between the slide 36 and the pusher 37 at the front of the hinge pin 38.
- the body 33 of the jack 34 is fixed by bolts or screws 27 to the first support piece 32, itself fixed to the sole 1 by bolts or screws 28.
- the cylinder 34 is, in the example shown, a single-acting cylinder which deploys the actuating rod 35 (and therefore the pusher 37) forwards (second direction) when it is supplied with pressurized fluid.
- the actuating rod 35 is retracted backwards by means of two tension springs 18 parallel to each other and to the direction of movement 14, and one end of which is integral with the body 33 of the jack , and the other end is fixed to the slide 36.
- the drive assembly comprises a second support part 29 which carries a plate 41 adapted to form the reception housing 30.
- the plate 41 and second support part 29 assembly is fixed to the sole 1 by screws 42.
- the plate 41 forming the receiving housing 30 is a generally rectangular plate having an opening 43 formed in the direction of movement 14, opposite and above the pusher 37 whose free end 39 projects vertically upwards above this plate 41.
- the opening 43 has a length sufficient to allow movement of the pusher 37 when the actuating rod 35 of the jack 34 moves, this pusher 37 having its free end 39 which remains projecting upward relative to the plate 41 forming the receiving housing 30 of the cassette 25. In this way, this free end 39 can interfere and cooperate with a bearing 44 integral with a cassette 25 in place in the box receipt 30.
- the plate 41 is planar horizontal, and comprises two longitudinal edges 45 parallel to the direction of movement 14, for guiding the cassette 25.
- the front part 46 of these longitudinal edges 45 is bent over the cassette 25 to form a holding the cassette 25 axially in an aligned position in the direction of movement 14.
- this plate 41 guides and maintains the cassette 25 in an aligned position in the direction of movement 14 while allowing movement of this cassette 25 relative to the soleplate 1 in translation parallel to the direction of movement 14, for mounting or mounting it.
- the pusher 37 acts as a latching locking latch bolt of the cassette 25 in the working position in its receiving housing 30.
- the forward displacement stroke of the actuating rod 35 is adapted so that the free end 39 of the pusher 37 can protrude forwards the position provided for the bearing 44 of the cassette 25, whatever the model used cassette, when the cassette 25 is in place in the receiving housing 30, abutting forward.
- the actuator 34 is actuated to retract the slider 36 backwards, the pusher 37 acting as a latch bolt as indicated above.
- the possible axial clearance between the pusher 37 and the bearing surface 44 is automatically compensated for by the inclination of the end 39 of the pusher 37 when it is pushed upwards by the spring 40.
- An unlocking finger 47 is mounted integral with the pusher 37 and extends perpendicular to the direction of movement 14 so as to be accessible from the outside by a light 48 provided by the first support piece 32. By operating this unlocking finger 47 downwards, the pusher 37 is lowered simultaneously, which enables the cassette 25 to be unlocked by sliding backwards relative to the plate 41 and to its receiving housing 30.
- the unlocking finger 47 therefore makes it possible to erase the pusher 37 integrally in the opening 43 for passage of the place face defined by the plate 41, in the direction of its distance from the cassette 25 until the bearing surface 44 of this cassette 25 can be moved with the cassette 25 and pass the push-button 37 backwards for the disassembly of the cassette 25.
- the plate 41 is placed above the second support part 29 and the body 33 of the jack 34, and has, between its side edges 45, a flat horizontal face 50 free upwards forming a bottom 50 of the receiving housing 30
- the cassette 25 comprises a lower flat face 49 intended to come into contact with the flat face 50 forming the bottom 50 of the reception housing 30.
- the cassette 25 also has a shape which allows it to be inserted and guided between the edges 45, 46 of the plate 41 forming the receiving housing 30, so that in the advanced position of the cassette 25 in the housing 30, it is aligned in the direction of movement 14 and held axially.
- the cassette 25 comprises a base plate 51 and an upper plate 52.
- the lower face of the base plate 51 forms the lower face 49 of the cassette 25 coming into contact with the bottom 50 of the reception housing 30.
- Both plates 51, 52 are assembled stacked one on the other by means of assembly screws 53.
- the two plates 51, 52 assembled form the cassette body 26.
- the opposite faces of the plates 51, 52 that is to say the upper face 54 of the base plate 51 and the lower face 55 of the upper plate 52, have recesses so that the two plates 51, 52 define between them a housing receiving and guiding in translation a pawl support 56 and a pawl 57 mounted on this pawl support 56.
- the pawl support 56 slides freely in translation relative to the two plates 51, 52, that is to say to the cassette body 26, in the direction of movement 14. To do this, the pawl support 56 has faces lateral 58 which come into contact and slide longitudinally along lateral guide edges 59 parallel to the direction of movement 14, formed in one and / or the other of the two plates 51, 52, (in the upper plate 52 in the embodiment shown in the figures).
- the support of pawl 56 has, towards its front end, the bearing surface 44 which projects downwardly and is intended to cooperate with the pusher 37 associated with the jack 34. This bearing surface 44 extends downwards in a longitudinal opening 60 formed through the base plate 51.
- This opening 60 comes opposite and has a shape similar to that of the opening 43 of the plate 41 forming the receiving housing 30 of the cassette 25 and which is crossed by the pusher 37.
- the bearing surface 44 extends downwards in the thickness of the base plate 51, so that it can be actuated by the pusher 37 which can protrude upwards inside the opening 60.
- the range 44 preferably extends at least substantially up to the level of the lower face 49 of the base plate 51.
- the pawl 57 is formed of an elastic blade fixed at its rear end 61 to the rear of the pawl support 56 and carrying, at its front end 62, a lug 63 projecting upwards and forwards in the form of U-bolt.
- the front end 62 of the pawl 57 can come to rest on a front end 64 of the pawl support 56.
- the flexible blade forming the pawl 57 is elastic in bending and curve with concavity oriented upwards in the non-deformed rest position so that the lug 63 is resiliently biased upwards, and can be moved downwards against the elasticity in bending of this flexible blade forming the pawl 57.
- the upper plate 52 has a slot 66 adapted to be able to be traversed by the 'lug 63, so that this latching lug 63 projects upwards beyond the upper horizontal face 67 of the upper plate 52 over a height sufficient to be able to come to cooperate with the strip 4 of lugs received on this face upper 67.
- the pawl 57 drives the strip 4 of lugs moving in the direction of movement 14, when the pawl support 56 and the pawl 57 are driven in transl ation by means of the pusher 37.
- the shape of the lug 63 being of the latch bolt type, the latter drives the strip 4 of lugs when it moves in translation forward towards the crimping station 5 , 7, but disappears by lowering in the light 66 when it moves in translation backwards, that is to say away from the crimping station 5, 7.
- the lug 63 is adapted to cooperate either with orifices provided in the pilot strip 13, or against each terminal 11, to drive the strip 4 of lugs.
- a compression spring 68 is supported by its rear end on a rear lateral extension 69 of the pawl support 56, and by its front end on a front stop 70 secured to the upper plate 52 (FIG. 7). This spring 68 therefore has the effect of recalling the pawl support 56, and therefore the pawl 57 and its lug 63, towards the rear until the extension 69 of the pawl support 56 comes into abutment against a rear stop 71 of the upper plate 52.
- the pusher 37 can cooperate with another bearing of the pawl support 56 to return it in the second direction, the jack 34 serving to drive the pawl 57 in both directions.
- the strip 4 of lugs is received and guided on the upper face 67 of the upper plate 52 by means of a rigid guide plate 72 fixed to the plate 52 and folded along several longitudinal fold lines so as to present a vertical longitudinal wing 73 s 'extending downwards towards the face 67 without reaching it, a clearance 74 being formed between this wing 73 and the upper face 67 of the upper plate 52 for receiving the strip 4 of lugs.
- This wing 73 is adapted to be able to be engaged in notches of the pods 11, so that it longitudinally guides the strip 4 of pods parallel to the direction of movement 14.
- the guide plate 72 thus forms, with the receiving face 67 , a tunnel for receiving the strip 4 of lugs.
- the strip 4 of lugs crosses this tunnel longitudinally, entering at its rear end and emerging at its front end.
- the cassette 25 comprises a braking plate 75 which has the function of exerting vertical pressure on the strip 4 of lugs by applying it to the upper face 67 of the upper plate 52 receiving the strip 4 of pods. This vertical pressure must be sufficient to prevent the rearward movement of the strip 4 of lugs during movements towards the rear of the pawl 57.
- the braking plate 75 is formed of an elastic blade in flexion folded longitudinally so as to have a longitudinal vertical wing 76 bearing against the strip 4 of lugs, in particular against the pilot strip 13.
- the brake plate 75 is fixed to the upper plate 52, with the guide plate 72 by means of screws 77.
- a spacer 78 and an elastic belleville washer 79 interposed between the guide plate 72 and the brake plate 75, make it possible to return the brake plate 75 downwards.
- the plate guide 72 is in fact mounted above the brake plate 75 which it comes to cap.
- the spacer 78 and the corresponding screw 77 pass through an oblong opening 80 of a maneuvering blade 81 interposed between the braking plate 75 and the upper plate 52.
- This maneuvering blade 81 comprises a cutout and a fold back towards the top forming a maneuvering lug 82 extending through notches 83 of the guide plate 72 and 84 of the brake plate 75.
- the maneuvering blade 81 also comprises a downward extension 85 extending in a longitudinal lumen 86 formed through the upper plate 52.
- a control blade 87 extending vertically longitudinally is fixed to the extension 85 in the lumen 86.
- This control blade 87 comprises two bearing surfaces 88, one in the vicinity of each of its front and rear ends projecting upwards so that they can be engaged in corresponding slots 89 of the brake plate 75.
- the bearing surfaces 88 have a front portion inclined towards front and down ( Figure 11) to allow their movement under the brake plate 75 when they exit forwards from the lights 89.
- control blade 87 comprises a downward extension 90 connected to the extension 85 of the maneuvering blade 81, and this extension 90 is extended forward by a reach 91 inclined forward and upward, adapted to be able to come into contact with a lateral extension 92 of the front end of the pawl 57 to lower the latching lug 63.
- the bearing surfaces 88 leaving the lights 89 have the effect of raising the braking plate 75 which no longer exerts pressure on the strip 4 of lugs.
- the bearing 91 comes into contact with the extension 92 of the pawl 57 to lower it, which erases the latching lug 63 in the slot 66.
- the strip can then be dissociated 4 of lugs and disengage it from the cassette 25 by moving backwards, the latching lug 63 and the brake plate 75 no longer being active.
- the upward movements of the brake plate 75 during the maneuver of the lug 82 are authorized thanks to the play provided by the belleville washers 79.
- the light 86 of the upper plate 52 allowing the passage of the bearing surface 91 is disposed laterally with respect to the pawl 57 so as to allow the cooperation of this bearing surface 91 with the lateral extension 92 of the pawl 57.
- the mounting of the plates 51, 52 also makes it possible to adjust the position of the guide plate 72 relative to the cassette body 26, in a transverse direction perpendicular to the direction of movement 14. To do this, a transverse movement of the two plates 51, 52 is authorized thanks to slots 93 in the upper plate 52, oblong in this transverse direction, and crossed by the assembly screws 53.
- an adjustment screw 94 with a conical end is inserted into a thread 95 of the upper plate 52 so that the conical end of the screw 94 comes into contact with a conical notch 96 formed hollow in the plate. base 51.
- the axis of the conical notch 96 is offset with respect to the axis of the internal thread 95 and of the adjusting screw 94 as shown in FIG. 9.
- Compression springs 97 are interposed between the two plates 51, 52 in the transverse direction to recall the two plates 51, 52 in the transverse direction opposite to the effect provided by the adjusting screw 94.
- the movements of the jack 34 driving the pusher 37 and therefore the pawl 57 of the cassette 25 are synchronized with the alternating vertical movements of the tool holder 2 by means of a contactor 98 cooperating with a vertical groove 99 formed in the rear face of the tool holder 2
- the device according to the invention advantageously has two vertical grooves 99 and two mounting positions of the contactor 98 making it possible to make the contactor 98 cooperate with one or the other of these two grooves 99.
- the contactor 98 is fixed by two screws 104 and the crimping device comprises three threads 105 for receiving the screws (FIGS. 14 and 15), only two of which are used for the screws 104 in each mounting position of the contactor 98.
- Each of the grooves 99 is adapted to achieve appropriate synchronization. It is indeed possible to wish that the forward movement of the strip 4 of lugs is effected either when the tool holder 2 is in the high position, or during its ascent or during its descent.
- a switch 100 makes it possible to deactivate the drive cylinder 34.
- the anvil support block (s) 19 has a vertical face forming a stop 101 towards the front, fixed relative to the sole 1, for the cassette 25 in the receiving housing 30.
- a front stop 102 fixed relative to the sole 1, but adjustable by a screw 103 in the direction of movement 14 relative to the sole 1, this front stop 102 being intended to receive the front end of the ratchet support 56 at the end of the forward stroke.
- the front stop 102 and the adjustment screw 103 are carried by the anvil support block 19 as shown in FIG. 4.
- the front stop of the ratchet support 56 can be secured to the cassette 25.
- the cassette 25 is entirely adapted in its shapes and dimensions to the strip 4 of lugs, so that the stroke of the pawl 57 can correspond to a displacement of the strip 4 of lugs equal to or slightly greater than the distance separating two lugs 11 on the strip 4 of lugs, and that the rearward stroke of the pawl 57 is greater than or equal to the distance separating two lugs 11, so that the latching lug 63 can come to cooperate with a new lug 11 to be supplied.
- the cassette 25 is also adapted to the shape of the lug strip 4 to guide it longitudinally in the direction of movement 14. To ensure correct positioning of the lugs 11 in the crimping station opposite the crimping axis 9, the screw 103 for adjusting the front stop 102 allows fine adjustment. However, most of the adjustment is obtained by means of the cassette 25. The same applies with regard to the transverse adjustment parallel to the crimping axis 9 which is obtained by action on the screw 94 allowing fine adjustment.
- lug strip 4 The change of lug strip 4 is extremely simple. Indeed, it suffices to disassemble the cassette 25 previously installed, then to install a new cassette 25 associated beforehand with its strip 4 of lugs.
- the pusher 37 pushing and locking the cassette 25 forwards. Any fine adjustment can be carried out by action on the screws 94 and 103, which is extremely simple and rapid. In most cases, such fine adjustment is also not necessary.
- the invention can be the subject of numerous variants with respect to the preferred embodiment shown.
- the cassette body 26 can have different shapes and dimensions and can be made in any other suitable manner.
- the cassette 25 of the embodiment shown is generally parallelepiped in the form of a thin, rectangular plate. Other forms can be adopted. It should be noted that the shapes and dimensions of the cassette 25 shown in Figures 6 to 11 are not strictly the same as those of the cassette 25 shown in the other figures.
- the invention is applicable for the automatic feeding of strips 4 of lugs, the lugs 11 of which extend axially in line following one another (and not parallel to each other), the strip 4 of lugs being supplied parallel to the axis 9 of crimping.
- the direction of movement 14 will coincide with the crimping axis 9 and the cassette and the various drive means will be placed either at the front or at the rear of the crimping device, and not on the side as shown.
