Definitions
- the invention relates to a device for forming wire, especially spring winding and bending machine, with a wire guide, the mouth of which is preceded by a wire feed device and its mouth, which defines a so-called wire axis Wire processing tools that can be moved into the wire movement path, especially associated with bending and cutting tools and with a transfer device comprising a gripper, by means of a shaped wire and from the rest of the wire severed wire section from the wire forming area is executable.
- the wire forming is done by winding and / or bending, in particular for the production of torsion springs, tension springs, tension springs with handle eyelets bent on both sides and with bent parts for example curved sections with any radius of curvature, the device or machine usually having a arranged continuously or optionally on the inlet side intermittently working wire feeder, with a Wire guide and several on the outlet side of the wire guide Arranged controlled tools is provided, which in selectable Order across and possibly along to that from the wire guide emerging wire are movable.
- the one from the wire guide emerging wire defines the so-called wire axis in relation to of all wire processing tools, namely bending and Cutting tools are set.
- a known Wire forming machine is the transfer device on one table arranged in front of the wire deformation area in the direction Can be slid back and forth parallel to the wire axis. This The arrangement hinders free access to the wire deformation area. The handling and control becomes significant difficult. It is also disadvantageous that the overall length of the Machine enlarged by the length of the transfer device becomes. It should be borne in mind that between the outlet side or mouth of the wire guide and the transfer device a so-called drop room for separated wire moldings is provided must be in the mostly a transport box to collect the processed wire moldings is positioned. With the described The arrangement of the transfer device is this box or the drop room mentioned is only accessible from the side. However, this access is usually from the side Tool tables hindered. After all this, the arrangement arises the mentioned transfer device in front of the wire deformation area as extremely disadvantageous.
- the object of the present invention is accordingly to create a device of the type mentioned in the introduction, which is characterized by a shorter overall length and good access to the wire deformation area.
- the Wire bending roll has the advantage that it bends when bending the impinging wire turns with the consequence that the wear the wire deformation area is reduced.
- the wire hits Deformation not always in the same place or on the same Point of the wire forming tool. This can be done considerably more springs with one and the same tool, i.e. without Manufacture tool changes than with the conventional static Wire forming tools, which also change the Incline tool change is required.
- the one mentioned Movability of the wire bending roll in vertical and / or horizontal Direction allows adjustment in a simple manner of the spring diameter.
- the spring diameter depends on the point of impact the wire on the circumference of the wire bending roll. To All of this is the wire bending roller and their storage around an extremely advantageous, namely universal Wire deformation tool.
- the positioning of the wire bending roll can be done manually or done by an electric motor. In the latter case it is the wire bending roll is assigned at least one drive, namely a drive for pivoting the same about an axis in parallel to the wire axis.
- the vertical and horizontal shift takes place by appropriate movement of the holding arm of the transfer device. The same applies to the shift parallel to Wire axis. This is also done by appropriate positioning the transfer device or the transfer device assigned cantilever according to claim 3.
- the gripper comprises two pivoting gripping jaws, whose inner sides facing each other are grooved, over the outer contour of a manufactured spring section the entire length of it corresponds. So that the spring section of the wire form are firmly gripped, in such a way that with further deformation of the cut wire end the spring section is held rigid.
- the transfer device preferably comprises one slidably mounted parallel to the wire axis Cantilever beam, at the free end of which there is a holding arm for the Gripping pliers is pivotally mounted, so that if necessary this together with the holding arm can be swiveled out of the wire deformation area is.
- the swinging out of the holding arm can be done hydraulically or manually. In the latter Fall can be swung out by a spring drive support.
- the device shown schematically in Figures 1 and 2, namely spring winding and bending machine 10 has a base 16 and a machine unit 17, the latter comprises a wire guide 11, the mouth 13 of which is a wire feed device 15 is upstream and a so-called.
- Wire axis 12 defining mouth 14 in the wire movement path 18 movable wire processing tools 19, 20, 21 and 22, in particular bending and cutting tools are assigned.
- the wire processing tools are in FIG. 1 as well as in FIG Figure 2 indicated by double-dash arrows, the Double arrows indicate the radial direction of movement relative to the wire axis View 12.
- the effective range of the processing tools mentioned defines a wire forming area 23 on the outlet side of the wire guide 11th
- a transfer device 25 comprising a gripper is a shaped wire section separated from the rest of the wire or wire blank 26 from the wire shaping region 23 out feasible.
- the transfer device is 25 above the mouth 14 of the wire guide 11 Can be pushed back and forth in the direction parallel to the wire axis 12 stored (double arrow 27), in such a way that that of the transfer device associated gripper 24 the shaped wire section or wire blank 26 after its separation from the rest Wire holds in a position in which the longitudinal axis of the severed Wire end 28 is aligned with the wire axis 12.
- the wire end 28 can thus by means of the on the wire axis 12 tools 19 to 22 in the desired Be further deformed without the wire blank 26 to a further processing station got to.
- the gripping tongs 24 are in the illustrated embodiment mounted to pivot back and forth about the wire axis 12. This allows the severed wire end 28 of the wire blank 26 bend in any conceivable radial position.
- the gripping tool 24 can be pivoted about the wire axis 12 is indicated in Figures 1 and 2 with the double arrow 29.
- the transfer device 25 comprises one parallel to the wire axis 12 slidably mounted (double arrow 27) cantilever 31, at its free, namely front end, a holding arm 32 for the Gripping pliers 24 are pivotally mounted (double arrow 33) such that it can be swung out of the wire forming area 23 if necessary is.
- Two drives in particular electromotive ones, can be mounted on the holding arm 25 Drives can be arranged, one of which for pivoting of the holding arm 32 and the other for actuating the Gripping pliers 24 are used. These drives are shown in FIGS. 1 and 2 not shown.
- the pivoting of the holding arm 25 by one pivot axis 34 extending parallel to the wire axis 12 can also be done manually if required.
- the gripping tongs 24 or alternatively the holding arm 25 is preferably attached to a cross slide in such a way that the gripping pliers if necessary vertically (double arrow 35) and / or horizontally (Double arrow 36) is movable. This is the separated feather form 26 can also be manipulated in the wire forming area 23 or the wire processing tools available there can be delivered at will. It is also conceivable that the gripping pliers 24 on Support arm 25 vertically slidable to store while the support arm 25 connected to the cantilever 31 via a horizontal guide is or vice versa. The horizontal and / or vertical travel the gripper is direct or indirect optional. In any case, horizontal traversability is necessary the transfer device 25 parallel to the wire axis 12 as well as the pivotability of the gripping tongs 24 about the wire axis 12th
- a wire bending roller 38 can be delivered, these in the present case is attached to the holding arm 32, namely via a holding and storage unit 39.
- the wire bending roll is accordingly 38, which is a so-called nutrolle, i.e. role deals with circumferential groove, with the holding arm 32 both vertically as well as horizontally movable.
- the wire bending roll should 38 still about an axis 40 parallel to the wire axis 12 be pivotable (see double arrow 41 in Figures 1 and 2).
- the wire bending roll 38 together with the associated holding and Bearing unit 39 can also be provided as a separate component his.
- a connection with the transfer device described 25 is therefore not a necessary requirement. This offers only in the present case in the described and illustrated Way.
- the Holding and storage unit 39 separate measures for horizontal and Vertical displacement of the holding roller 38 to this in a Bring the desired position relative to the emerging wire 37 to be able to.
- the cantilever 31 is, for example, by means of a hydraulic or electric motor drive in the direction parallel to Wire axis 12 reciprocable.
- the vertical and horizontal shift of the holding arm 25 in the direction of the double arrows 35, 36 can also be hydraulic or electromotive Drives take place. These are then preferably located on the holding arm 25.
- the transfer device has 25 an L-shaped basic shape, the long leg through the support arm 31 and the short leg through the holding arm 32 are defined.
- the gripping pliers 24 are located on the side of the holding arm 25 Holding arm 25 can be completely up around the axis 34 swing out the wire forming area 23.
