Definitions
- Crimping device for an element to be crimped on a part
- the present invention relates to a device for crimping an element to be crimped on a part, in particular on a part of a motor vehicle.
- Crimping is a simple operation of assembling two pieces. The material is deformed, either of the part on which the crimp element is crimped, or of the crimp element itself, or of both. Crimping is used to immobilize parts without welding. For example, to fix a nut on a part, without deforming it, it is possible to make a nut with a central ring, or guide, which will be folded on the other side of the part, previously pierced, as for a rivet; this is called a crimped nut. Like a rivet, this assembly is indémontable. It is also possible to fix a crimp element by deformation of the part on which this element is fixed. In this case, the part may not have a hole.
- the crimping device also called crimping, comprises a punch, which is movable in translation, and a percussion matrix, located under the free end of the punch.
- the crimp element is struck by the free end of the punch. It is the shock of the element to be crimped, struck on the part, by the punch, which deforms the latter and / or the element to crimp, against the so-called "operational" face of the matrix, and allows the fixation of the element to crimp on the piece.
- the device generally comprises a magazine and a system for supplying crimping elements.
- the magazine contains a plurality of crimping elements which are moved, one after the other, at the entrance of a passage formed in a positioning part of the crimp element.
- This passage has an exit which opens above the operational face of the matrix.
- the free end of the punch moves, in and beyond this passage, between a high position, in which the free end is located above the entrance of the passage, and a low position, located in the passage and which allows crimping.
- the magazine feeds a crimp member at the entrance of the passage, movement of the free end of the punch causes the crimp member to pass into the passageway and provides crimping at the outlet of the passageway.
- the punch deforms the crimp member from below but in a manner that does not allow its crimping.
- the bottom crimp member tends to be crushed and swollen, deteriorating the locating piece, which cracks, and / or the free end of the punch.
- the crimper must then be stopped immediately and an operator must come and remove the elements to be crimped and replace the positioning part and / or the punch.
- the present invention proposes a device for crimping a crimping element on a part which has a crimping surface, said device being of the type comprising, in known manner: a punch, movable in translation in a direction D and having a free end, capable of applying, in said direction D, on said crimping element, a given intensity force for crimping said crimping element on said crimping surface;

- said means for maintaining said matrix comprise a frangible element capable of breaking when a force of intensity greater than a limit value is exerted on said operational face, whereby when said punch exerts, on said matrix, said force of intensity greater than said limit value, said frangible element breaks and said matrix is displaced by said punch.
- the displacement of the die by the punch allows to move it away from the free end of the punch.
- the punch actually exerts a force on the matrix, since the energy of the impact between the element to be crimped and the part is not dissipated in the deformation. of one and / or the other of these elements. If this force has an intensity greater than a given limit value and may damage the punch and / or the positioning piece, breaking the frangible element that holds the die can dissipate the energy of the shock caused by the displacement. of the punch, in the displacement of the matrix. This is away from the free end of the punch and is no longer subject to the repeated blows of the latter. It is no longer likely to be damaged.
- the device comprises means for detecting the rupture of said frangible element and a power supply and said detection means are coupled with means for cutting off said power supply so that the breaking of said frangible element actuates said breaking means. which cut said feed through said detection means.
- the breaking or breaking of the frangible element causes not only the displacement of the matrix, but also the shutdown of the device, by depriving it of energy. Any risk of deterioration is thus quickly discarded.
- the displacement of the matrix is not limited according to the invention.
- the device comprises a frangible abutment on which abuts said percussion matrix. In this case, the displacement of the matrix takes place in the direction D of displacement of the punch.
- the device comprises a support of said matrix, interposed between said matrix and said frangible stop and a guide which comprises a recess in which said support is able to move in translation in said direction D, whereby when breaking said frangible abutment, said support can move in said guide to move said matrix away.
- the device then comprises return means, mounted in said guide and which are able to exert on said matrix, a force which pushes it towards said punch.
- return means mounted in said guide and which are able to exert on said matrix, a force which pushes it towards said punch.
- a connector is movably mounted in translation along said direction D, in said guide, under said frangible stop, said connector having a longitudinal outer surface which has a first and a second portion, of different section, and a probe is arranged facing said first portion, so as to detect the translation of said connector, when breaking said frangible stop, by detecting the section variation of said connector, when said connector is pushed by said matrix, during the breaking of said frangible stop.
- the device may also comprise a magazine which contains a plurality of elements to be crimped and which comprises a system for feeding one of said crimping elements, said supply system being able to drive one of said crimping elements of said magazine so that said free end of said punch exerts on it said force of given intensity.
- the free end of said punch may comprise an interchangeable tip, which, in case of deterioration of this tip, makes it possible not to change the whole punch.
- the change of the tip is fast and does not require disassembly.
- the mode of cooperation between the free end, or the aforementioned endpiece, and the crimping element is not limited according to the invention. It can be a simple contact.
- the free end of said punch is adapted to cooperate by interlocking with said crimping element.
- free end is meant, in the sense of the present invention, the free end of the punch, when the latter does not have a nozzle, or the tip, when the punch comprises such a tip.

- the frangible plate 6 extends transversely to this recess 71 and is inserted into a slot, transverse to the guide 7, located below the entrance of the recess 71.
- the recess 71 contains a connector 8, which is arranged under the frangible plate 6 and which can move in vertical translation in the passage 71.
- the connector 8 is in the form, for example, of a cylinder which has an end upper 81, disposed directly below the wafer 6, and a bearing 83 of larger section, disposed at its other end.
- the section of the bearing 83 corresponds substantially to the section of the recess 71.
- the portion above the bearing 83 has a lower section.
- Reminder means 9 are arranged on the bottom 72 of the recess 71.
- the end of the connector 8, located at the bearing 83 rests on these return means 9 which exert a force which pushes the connector 8 towards the entrance to the recess 71.
- the recess 71 communicates with a conduit 73, which is substantially perpendicular thereto.
- the conduit 73 is formed near the bottom 72 of the recess 71 and passes through the thickness of the wall of the guide 7.
- the head 101 of a probe 10 is inserted into the conduit 73 and comes into contact with the bearing 83.
- probe 10 is connected to means 110 for breaking the power supply, electrical or otherwise, of the device. This power supply serves, in particular to move the punch 1.
- the device also comprises a magazine 120 which contains nuts 3 which are crimped on a part 20.
- the magazine 120 comprises a supply system (not shown) nuts 3, which moves the nuts 3 and has them at the input 23 of the passage 21, when the punch 1 is in the up position.
- the nuts 3 have a deformable ring 31 which serves for fixing them by crimping.
