Definitions
- the present invention relates to a crimping insert for a hand-operated press tool according to the preamble of claim 1 and a hand-operated press tool.
- Generic crimping dies for manually operated crimping tools are usually designed to insert wire end sleeves that are individually threaded onto conductor cable ends into the crimping die and to fix them using the crimping tool.
- a punch part and a die part, by means of which the ferrule is pressed with the conductor wire, are usually attached to the press jaws of the press tool, which form a pliers jaws.
- the disadvantage is that with a large number of wire ends to be crimped with such wire end sleeves, the time required for the individual work steps to be carried out is relatively high.
- crimping tools in which as strips mitei nander-connected ferrules are received in a dedicated receptacle ger within one of the handles or in the area of the pressing jaws of such a tool, which, however, defines the use of such a pressing tool for crimping.
- the object of the present invention is to provide a crimping insert for a manually operable pressing tool and a pressing tool which can be attached to the pressing tool in a number of ways and with which wire end sleeves connected to one another can be processed in a simple manner.
- the crimping insert according to the invention for a hand-operated pressing tool with pressing jaws aligned parallel to one another and vertically movable towards or away from one another for processing strips connected to one another has a ferrule which can be attached to a first of the pressing jaws Stamp part and a die part which can be fastened to a second of the press jaws.
- the die part has a feed area with a receiving opening for feeding the strip into a severing and pressing area of the die part.
- a holding element with which the strip can be frictionally fixed in the feed area.
- a cutting edge for separating a foremost ferrule from the strip is arranged on the stamp part, in particular molded on.
- the punch part and the die part each have a guide part for guiding a Senkbewe movement of the punch part relative to the die part.
- the guide part of the stem part has at least one web which can be lowered into a guide recess of the guide part of the die part.
- Such a web can be molded or attached to the stamp part in a simple manner.
- the formation or introduction of a guide recess in the die part is also extremely simple and inexpensive to bewerkstelli conditions.
- the guide part of the punch part has two webs arranged parallel to one another, separated from one another by a gap, which can be lowered into the guide recess of the guide part of the die part.
- the folding element is designed as a brush.
- the bristles of such a brush ensure reliable flaming of the strip of ferrules, with the flaming on the other hand being sufficiently loose to allow the ferrule strip to be pushed forward easily.
- the folding element has a guide web guided in a guide groove of the die part and bristles protruding from the guide web and thus enables a simple installation and simple replacement of such a folding element.
- the folding element is secured by a pin axially to the longitudinal axis of the folding element in the guide groove of the die part in order to reliably prevent the folding element from slipping through in the guide groove in the longitudinal direction.
- the manually operated crimping tool is characterized by a crimping insert as described above.
- FIG. 1 shows a schematic isometric representation of an embodiment variant of a crimping insert according to the invention attached to a manually operable pressing tool
- FIG. 2 is an isometric exploded view of the crimping insert shown in FIG. 1 and a strip of wire end sleeves connected to one another,
- Figure 3 is an isometric individual representation of the assembled crimp insert
- FIG. 8 to 10 of FIG. 1 corresponding representations of a crimping insert attached to a pressing tool in different functional positions.
- the reference number 2 denotes a manually operable pressing tool, preferably in the form of pliers.
- An embodiment variant of a crimping insert 1 according to the invention is used in their pliers jaws formed by pressing jaws 23, 24.
- the crimping insert 1 is used in particular to process strips 6 of wire end sleeves 61 joining together, as shown by way of example in FIGS. 1 and 2.
- Each of the wire end sleeves 61 consists essentially of a metal sleeve 63 into which the stripped ends of a conductor cable 8 are inserted and a jacket 62 that is slipped over an insulation of the conductor cable 8.
- the strips 6 of wire end sleeves 61 connected to one another are held together over the sheaths 62 of the end sleeves 61 to form a strip.
- the crimping insert 1 has a punch part 3 that can be fastened to a first of the press jaws 23, 24 and a die part 4 that can be fastened to a second of the press jaws 23, 24.
- the two components have respective plug-in areas 31, 41 with bolt receptacles 32, 42 formed therein.
- the plug-in areas 31, 41 are web-like and are inserted between tween a respective press jaw 23, 24 forming sheets arranged parallel to one another and with the aid of a bolt (not shown) that is inserted through bolt receptacles 25, 26 in the first press jaw 23 and the second press jaw 24 as well as through the bolt receptacles 32, 42 is attached to the pressing tool 2.
- the crimping insert 1 If the crimping insert 1 is not required, it can be removed from the pressing tool 2 in a simple manner by loosening these bolts.
- the die part 4 has a feed area 43 with a receiving opening 48 for feeding the strip 6 into a severing and pressing area 49 of the die part 4, which is provided deeper in the jaws of the pliers when installed.
- the severing and pressing area 49 of the lowering part 4 is designed here as a groove lowered with respect to a bearing surface 44 of the feed area 43, on the bottom 491 of which the ferrule 61 previously severed from the strip, together with an end of a conductor cable 8 inserted into the ferrule 61 is pressed with the aid of the crimping die 34 of the die part 3.
- the bearing surface 44 of the die part 4 is in two planes, namely a first bearing surface 441 in which the sheaths 62 lie and a second bearing surface 442 on which the metal sleeves 63 of the wire end sleeves 61 rest, trained.
- the bearing area 43 of the die part 4 is aligned so that the Homme senstMailkette can be advanced through the entrance of the pliers jaws of the pressing tool 2 in the direction of the rear part of the pliers jaws.
- the wire end sleeves 61 which are cast onto one another via their sheaths 62, are aligned in such a way that a conductor cable end to be crimped can be inserted into the wire end sleeve 61 from a side surface of the pressing jaws 23, 24.
- a retaining element 5 is arranged in the bearing area 43, with which the strip 6 can be frictionally fixed in the guide area 43.
- the holding element 5 is preferably designed as a brush.
- the holding element 5 has a guide body 51 guided in a guide groove 47 of the die part 4, from which bristles 52 protrude which, when the sleeve strip chain 6 is inserted into the die part 4, press the sheaths 62 of the wire end sleeves 61 against the first bearing surface 441.
- the guide body 51 is preferably made of a dimensionally stable plastic or also of metal, while the bristles 52 are preferably designed as elastic plastic strips.
- the guide body 51 is there preferably of a T-shaped cross-section.
- the guide groove 46 for receiving the guide body 51 is of a corresponding T-shaped shape, which holds the holding element 5 in a form-fitting manner in a direction z at a predetermined distance from the first bearing surface 441.
- the bearing area 43 of the die part 4 has a bore 47 which is used to receive a pin 7, in particular a threaded pin, and which presses against a top of the guide body 51 facing away from the bristles 52. It is also conceivable to make a blind hole in the guide body 51 into which the pin 7 protrudes. Other ways of fixing the guide body 51 on the die part 4 are also conceivable.
- the punch part 3 has a cutting edge 33 which is used to separate a foremost wire end sleeve 61 from the sleeve strip chain 6.
- the cutting edge 33 is formed in one piece on the punch part 3.
- the stamp part 3 also has a guide part 35 which serves to guide a lowering movement of the stamp part 3 relative to the die part 4.
- the guide part 35 has at least one web 36 which can be lowered into a guide recess 451 of the guide part 45 of the die part 4.
- the guide part 35 has two such webs 36, which extend from a base piece and which are aligned parallel to one another and which are separated from one another by a gap 37, so that the guide part 35 as a whole is approximately U -shaped.
- the gap 37 serves to accommodate a portion of the pressing jaw 24 so that when the pressing tool 2 is actuated when the pliers mouth formed by the pressing jaws 23, 24 is closed, the pin-like webs 36 can slide along the outer sides of the lower, second jaw 24.
- the stamp part 3 furthermore has a crimping stamp 34 between the cutting edge 33 and the guide part 35, with a pressure surface 341, which is optionally provided with transverse webs 342, as is shown by way of example in FIGS.
- the crimping die 34 is arranged in an area of the die part 3 in which a respective metal sleeve 63 of the wire end sleeve 61 comes to rest on the bottom 491 of the severing and pressing area 49 of the die part 4.
- the cutting edge 33 extends approximately parallel to the crimping die 34 in an area in which the jackets 62 of the wire end sleeves 61 are advanced into the severing and pressing area 49 of the die part 4.
- the die part 4 also has a guide part 45 in an area behind the severing and pressing area 49.
- This guide part 45 is approximately cuboid here and has a central guide recess 451 which is used to receive the guide part 35 of the stamp part 3.
- the stamp part 3 also has an insertion area 31 with a Bolzenholz receiving 32, with which the stamp part 3 can be fixed in a simple manner between the Me tallblechen of the first press jaw 23.
- the sequence of crimping a conductor cable 8 is described below with reference to FIGS.
- FIG. 8 shows the state in which the sleeve strip chain 6 is pushed so far into the bearing area 43 of the die part 4 that a foremost wire end sleeve 61 is pushed into the severing and pressing area 49 of the die part 4.
- the cutting edge 33 shears the foremost end sleeve 61 from the rest of the sleeve strip chain 6.
- the wire end sleeve 61 together with the conductor cable end 8 inserted therein has reached the die bottom 491 in the severing and pressing area 49 of the die part 4, which is done by pressing the crimping die 34 and an inclined surface of the shearing area 33 of the die part 3, the conductor cable end 8 pressed in the ferrule 61 and thus creates an electrically conductive connec tion.
- the crimped conductor cable end 8 can then be removed. Subsequently touched the sleeve strip chain 6 can be manually advanced a bit further in the Lagerbe rich 43 of the die part 4 until the next Aderendhül se 61 protrudes into the separating and pressing area 49 of the die part 4 and a new crimping process can be carried out.
