Definitions
- Known straightening devices for straightening wire have a plurality of interchangeable straightening jaws as wear parts, via which the wire is drawn off.
- the straightening jaws are made of different materials.
- straightening jaws made of gray cast iron are used for reinforcing steels.
- these wear out relatively quickly, especially if the wire to be dressed has an outwardly protruding profile. This results in short service life of the straightening jaws.
- the present invention is based on the object of designing straightening jaws of the type mentioned at the outset in such a way that they enable inexpensive operation of a straightening device. This object is achieved by the combination of features of claims 1 and 8.
- FIG. 1 and 2 show the process of straightening a wire 1 in a rotating straightening body 2.
- Five pairs of straightening jaws 3 bend the continuous wire 1 as shown in FIG. 2 in a wave-like manner, the waves constantly changing due to the rotation of the straightening body 2. This removes the tension in the wire and the wire leaves the straightening device in a straight form and we are then cut to length.
- FIGS. 3 and 4 A straightening jaw 3 according to the invention is shown in FIGS. 3 and 4.
- An approximately cuboidal chuck 31 is provided with a longitudinal directional groove 32 on an end face 36.
- an inlet part 33 and an outlet part 34 are formed from the groove 32.
- the inlet and outlet parts are preferably identical, symmetrical to the central plane, differing from the illustration in FIG. 4.
- the inlet part 33 and the outlet part 34 each have a base inclined towards the end face 36. They converge against each other.
- the chuck 31 has on both sides a bulge 37 bulging like a cylinder segment, similar to a cylinder 40 penetrating the chuck 31, the axis of which is perpendicular to the end face 36.
- This cylinder 40 has a central bore 41, the axis of which is also perpendicular to the upper end face 36 and into which a straightening insert 50 is inserted.
- the straightening insert 50 has a saddle shape at the upper end Straightening boss 35, which connects the inlet part 33 and the outlet part 34 to one another and forms the groove 32 together with these.
- the bore 41 opens into a concentric countersink 42 which has a stop surface 43 at at least one point.
- the straightening insert 50 is cylindrical.
- the straightening insert 50 has a concentric flange 51 which has stop surfaces 52 which match the stop surfaces 43 of the countersink 42. The straightening insert 5 thus remains aligned in the bore 41.
- the set screws 11 in the straightening body 2 determine the position of the straightening jaw pairs 3 and thus press against the side of the chuck 31 in which the recess 42 and the flange 51 are located.
- the straightening insert 50 thus does not have to be soldered in. It can be easily replaced if a wire with a different diameter has to be processed or a worn straightening insert has to be replaced.
- the feed 31 can therefore be used repeatedly.
- the straightening jaws 3 can have a flat base surface 38 opposite the end face 36 or it can be provided with lugs 39, as the illustration of the straightening jaws 3 in FIG. 1 shows. These lugs 39 protect the screws 11 in the event of a wire break.
- the material of the straightening insert 50 depends on the intended use.
- the straightening insert 50 advantageously consists of hard metal.
- the lining 11 preferably consists of gray cast iron. Both the lining 11 and the straightening insert 50 can be produced inexpensively. Due to the easy interchangeability, the downtimes of the straightening device are kept short.
- the embodiment 5 - 7 differs from that of FIGS. 3 and 4 mainly in that the flange 51 is omitted on the straightening insert 50.
- the straightening insert 50 is cylindrical over its entire height. It has an oval cross-section to prevent rotation (Fig. 7). Accordingly, the opening 41 is oval.
- the straightening insert 50 can have ample play of up to several millimeters in the opening 41.
- the opening 41 has a shoulder 44 at the top of the straightening groove 32, against which flat end faces 53 of the straightening insert 50 rest.
- the opening 41 is closed at the bottom by a cover 60 which is fitted with a e.g. circular cylindrical pin 61 is centered in the opening 41 and abuts with a flange 62 on the lower end face 38 of the chuck 31.
- the lid 60 is e.g. held by a bracket 63 made of spring steel. This can be inserted in a groove 64 of the cover 60 and snaps on top with hooks 65 in grooves 66 in the thickenings 37 of the lining 31.
- the straightening insert 50 can be produced particularly inexpensively.
- the feed 31 can be reused several times.
