Definitions
- the invention relates to a wire bending machine, in particular for Bending structural steel wires, with one or two longitudinally movable, one bending head receiving bending slide, the bending head two towering, between an insertion slot aligned in the longitudinal direction for insertion a bending mandrel to release a piece of wire to be bent as well as on the Bending end of the wire piece facing side of the mandrels one by one parallel pivot axis running in the area of the insertion gap swivel-adjustable bending arm with one in the same direction as the bending mandrels towering bending pin and on the mandrel side facing away from the bending end a wire clamp with two jaws that can be moved transversely to the splitting direction having.
- the bending radius to be selected is the Wire pieces depends on the respective wire diameter and this bending radius is determined by the diameter of the mandrel, can be based on the known Wire bending machines with one and the same bending tools only ever wire pieces a certain diameter range adapted to the respective mandrel diameter bend and the bending of wire pieces accordingly different Diameter ranges requires a conversion of the bending machine suitable bending tools.
- the invention is therefore based on the object of a wire bending machine to create the kind of bending of wires of different kinds Allowed wire diameter with constant bending tools and is also characterized by its diverse bending options.
- the invention solves this problem in that the two mandrels each at least two arranged symmetrically to the longitudinal center plane of the insertion gap, radially offset against each other towards the insertion gap and a common, mandrel sections defining the insertion gap defining the tangential plane different, decreasing from the mandrel section to the mandrel section Diameter include that preferably also the bending pin the same pin sections in number, height and diameter forms, whose axially offset axes in a common Axial plane through the pivot axis of the bending arm and their radial distances from the swivel axis the dimension of half the insertion gap enlarged section diameter exceeds, the bending mandrels and possibly the swivel arm with the bending pin in the axial direction compared to an axis normal given by a support for the wire pieces Bending plane height-adjustable according to the mandrel sections are, and that the wire clamp from an open position with the tangential planes of the mandre
- the mandrels opposite the bending plane can the mandrels on each to be matched to bending diameter ranges by the for these diameter ranges match mandrel sections in an opposite to the Bending level can be brought to the correct height.
- the pieces of wire can then be bent with a suitable bending radius, the adaptation of the mandrels to the respective wire diameter every bending process by simply selecting the appropriate mandrel sections and corresponding stroke adjustment and therefore different pieces of wire can also be bent correctly in any order in succession.
- the wire clamp by selectively applying one or the other Clamp not only for actually clamping the wire pieces, but also used to place the wire pieces on the mandrel to be used, so that even with small wire diameters compared to the insertion gap proper bending to one side or the other.
- a bending pin gradation corresponding to the mandrel gradation in Spigot sections that are not absolutely necessary in normal bending processes would be the bending process especially when bending by more than 90 ° improved because of the rolling motion of the corresponding pin sections at the bending end of the piece of wire, smaller relative movements between Pin section and piece of wire occur and thus a risk of damage to the Wire surface must be prevented.
- the slide drives, the drives for the swivel arms, the lifting drives for the mandrels and swivel arms and bending pins and especially the wire clamps can be controlled individually be what but with an appropriate control device without Difficulties is possible.
- the bending head has an additional bending stop on the bending mandrel on the outside of the movement path of the bending pin with a lateral offset is arranged opposite the tangential planes of the mandrels itself with a swiveling movement of the swivel arm with its bending end both on the associated mandrel and on the bending stop
- the lateral offset of the bending stop compared to the mandrel specifies the distance between the Z-legs. Is the bending stop raised from a basic position to a bending position supported, this bending stop can be used optionally, without in the basic position the end of the wire piece moving during bending to be.
- the bending head on the bending slide to a vertical Longitudinal plane is inclined and defines a longitudinally inclined bending plane
- the bending slide a cover with a recess for the Bending head and a support for the wire pieces, which cover a starting position parallel to the bending plane can be folded up into a drop position is stored.
- This inclination of the bending head and the inclination given with it the bending plane makes it easier to insert the wire pieces for the bending process and then after the bending process, bringing out the bent pieces of wire, for which it is sufficient to place the wire pieces in the insertion gap when the cover is folded down let it fall or the cover in its original position is below the bending level to fold up, so that when folding up bent piece of wire with the support when the wire clamp is open again be lifted out of the insertion gap and thrown out of the machine can.
- the piece of wire then falls into a gutter along a sliding path or the like .
- the cover is with a sliding Protective shield to close the recess, so that after the With the wire clamp still closed, bend the bending head down out of the Extends recess and the protective shield closes the recess, whereby with the following ejection, the wire pieces can no longer get caught is.
- the cover has an edge strip with a runway for one to be bent End of the piece of wire becomes the end of the piece of wire when bent by more than 90 ° raised by the run-up to the runway from the bending plane, so that closed bending forms are also possible with a correspondingly multiple bending can be reached, with the two bending ends then lying on top of each other come.
- the bending head has lifting rods that can be raised are arranged along the tangential plane of the lower mandrel.
- This Catch rods make it easy to bend the wire rods from above to drop the feeder device provided for the bending machine and they into the insertion gap via the catching rods raised to the catching position or insert the open wire clamp.
- the feeder device is advantageously with the one directly to the straightening and cutting device Wire straightener connected wire outlet in which the wire pieces also positioned via appropriate directional stops for further processing are ready.
- a wire bending machine 1 has a machine frame 2 with two longitudinally movable Bending slide 3, with each bending slide 3 having a bending head 4 two towering insertion slits between them 5 for the insertion of a piece of wire W to be released, bending mandrels 6, 7 and one around a mandrel parallel, in the area of the insertion gap 5 running swivel axis S swivel-adjustable bending arm 8 velvet one in the same direction as the bending mandrels 6, 7 towering bending pin 9 and a wire clamp 10 from two jaws movable transversely to the splitting direction 11, 12 records.
- the bending mandrels 6, 7 form three to the longitudinal center plane E of the insertion gap 5 symmetrically arranged mandrel sections 61, 62, 63; 71, 72, 73 different, upwards from mandrel section to mandrel section of decreasing diameter D1, D2, D3, which are radially offset from one another towards the insertion gap 5 are and in each case a common tangential plane delimiting the insertion gap 5 Determine T6, T7.
- the bending pin 9 also has three pin sections 91, 92, 93, which are adapted in their dimensions to the mandrel sections and their axially offset axes in a common axial plane A lie through the pivot axis S and their radial distances a, b, c from the swivel axis S in each case the dimension of the half insertion gap width increased Section diameter exceeds D1, D2, D3.
- the bending mandrels 6, 7 and the swivel arm 8 with its bending pin 9 are opposite in the axial direction the bending plane B is adjustable in height, so that for bending the wire pieces one or the other depending on the respective wire diameter Mandrel and tenon sections can be used.
- the wire clamp 10 is in the open position with its jaws 11, 12 on the Tangential planes T6, T7 aligned and can optionally be operated of one or the other jaw 11, 12 close, so that when using the one or the other mandrel 6, 7 the wire when clamping to the respective mandrel is created by closing the clamp accordingly.
- the bending head 4 has an additional bending stop on the bending mandrel 6, 7 13 on the outside of the path of movement of the bending pin 9 with lateral offset V is arranged opposite the tangential planes T6, T7 and off a lowered basic position in a bending position protruding into the bending area can be raised.
- the bending head 4 is inclined on the bending slide 3 to a vertical longitudinal plane and determines a longitudinally inclined bending plane B, the bending slide 3 is equipped with a cover 14 which has a recess 15 for has the bending head 4 and a support 16 for the wire rods to be bent forms.
- the cover 14 is also arranged with a cross-slide Protective shield 17 provided that with the mandrel or bending pin lowered close the recess 15 except for the area around the wire clamp 10 can.
- the cover 14 of one of the bending slides carries one in the lower edge area Edge strip 18 with a run-up path for a wire piece end to be bent, so that this is lifted out of the bending plane when bending through larger angles and is bent transversely and bending a closed bow shape with side by side Wire ends is made possible.
- Retractable catch rods 19, 20 are also provided on the bending head 4 are arranged along the tangential plane T7 of the lower mandrel 7 and facilitate the insertion of the wire rods to be bent into the insertion gap 5 should.
- a piece of wire W this piece of wire from a discharge device 21 positioned in the insertion gap 5 thrown between the two bending heads 6, 7, the bending slide 3 in the longitudinal positions provided for the first bending process process and the covers 14 of the slide in their bending plane parallel Starting positions folded down and the protective shields 17 are withdrawn.
- the Recordings 16 of the covers 14 thus determine the bending plane B and accordingly the respective diameter of the wire piece W to be bent the mandrels 6, 7 and the swivel arm 8 with the bending pin 9 in the higher position in which the mandrel and the diameter Pin sections come into effect.
- the jaws 11, 12 of the wire clamps 10 are open and the interception rods 19, 20, as indicated by dashed lines in FIG. 1, raised so that the piece of wire falling off the ejector slides along the catch rods and both in the insertion gaps 5 and also come to lie in the open wire clamps 10 in the correct position (FIG. 3a).
- the lower ones Jaws 12 actuated and the wire piece W against the upper standing Clamping jaws 11 clamped so that the piece of wire also on the upper mandrels 6 is present.
- the bending heads 4 can be used in a simple manner with the help of the bend stop 13 raised into the bend position also a Z-bend can be achieved, for which purpose only to clamp the inserted wire piece W. and by means of a corresponding swiveling movement of the swivel arm 8 of the bending pin 9 between the corresponding mandrel 6 and the Bending stop 13 is to be used.
