- Each sled guide body is on its own the end area facing away from the wire guide about a perpendicular to the wire guide axis and parallel to a central plane running through the wire guide axis Swivel axis swiveling, with both winches on different sides of this Middle plane are arranged.
- Each of the two winches has its own cam mechanism assigned to the one sled in front of the carriage in its guide and pushes back, while on the other winch it pushes the carriage guide body back and forth panned and both movements are program-controlled to each other.
- this known winch device a change in the wind direction to be generated Coil springs take place, however, is the implementation of a plurality of mechanical Conversion work required, in particular a change in the kinematic transmission between Cam and winch as well as a change in facilities on the Winch apparatus itself is required, which is still relatively complex and cumbersome.
- the invention is based on the object of a spring winch device to provide the type mentioned at the outset, in which the change in the wind direction of the generated springs possible while largely avoiding mechanical conversion work is, and yet has a relatively simple structure.
- a spring winch device in particular for spring coiling machines, for the production of either right-hand or left-hand winding Coil springs made of wire, with feed rollers for conveying the wire along one Wire guide axis through a wire guide, with two winches, each one Has carriage guide body in which a carriage is slidably arranged so that a winch tool connected to the carriage relative to the wire exit point of the wire the wire guide is guided in a linearly movable manner, with each slide guide body on its End area facing away from the wire guide about a perpendicular to the wire guide axis and directed parallel to a central plane running through the wire guide axis Swivel axis is pivotable, both winches on different sides of this Arranged in the middle plane, each winch apparatus has a drive for moving the carriage and a cam mechanism controlled by a cam for pivoting the Carriage guide body is assigned around the pivot axis, the cam gears both winches share a common one, controlled by
- cam disc used in the invention common to both cam gears to the fact that a total of only three servomotors are to be provided and therefore with three Axes the entire basic principle of spring winding is covered. You can reach everyone Advantages only by using a third motor, without the use of another Motors would be required, as in the known spring winch device according to DE-OS 198 25 970 is used. In addition, this can also be done with this prior art used complicated arrangement one above the other and relative to each other in Carrying tables for the tool carrying devices and which can be moved in different directions the, also quite complicated connection mechanism on the one table, which at one Moving a second table to move two more tables is required be completely dispensed with.
- the individual motors for driving the common cam as for the two Drives for moving the slides are via an electronic program control coupled with each other, which ensures that the for winding springs in one
- the direction of the wind for each motor used is program-controlled, precisely the movements perform, which are required for the manufacture of the desired spring shape.
- the cam mechanism works one at a time Winch apparatus with the drive for the movement of the carriage of the other Winches together program-controlled, whereby coil springs become one Have the wind direction established in the two-finger system. Should other people's feathers Wind direction will be generated, the cam gear of the other Winch apparatus with the other drive for the linear movement of the slide interconnected.
- the forming process when the Causing wire in the one-finger system is preferably the cam mechanism of a winch with the drive for the movement of the carriage of the same winch coupled programmatically, i.e. one winch is in use while the other Winch is inactive.
- the spring winch device can be used as a drive for the movement of the In principle, any suitable type of drive can be used with every winch. However, it is very particularly preferred if as a drive for the movement of the carriage Each winch has a cam that can be rotated by a program-controlled motor is provided, the cam movement is forcibly transmitted to the carriage. This has the great advantage that the occurring due to the positive control Weight and acceleration forces the accuracy of the movement of the slide or tool holder.
- the axis of rotation is particularly preferred in the spring winch device according to the invention
- the cam plate common to the two cam mechanisms is arranged so that they Extension of the wire guide axis cuts vertically and lies in the middle plane. This allows a mirror-symmetrical arrangement of the cam mechanism on both sides of the Reach the mid-plane, resulting in the same loads in both wind directions of the springs each activated cam gear leads.

- the servo motor 64 is activated, which program-controlled the control cam 68 via the gear 60, intermittently forward and drives backwards.
- the radial movement of the cam 68 is via the rollers 72 transferred to the carriage 40 of the upper winch apparatus 30 and the upper winch tool 20 is linearly back and forth in a closer / front or further / rear oblique position moved relative to the wire exit point of the wire 14 on the wire guide 16.
- the movement that is legally coordinated with the movement of the upper winch tool 20 of the winch tool 22 of the lower winch apparatus 32 is program controlled by the control cam 88 correspondingly driven by the servomotor 86 via the gear 84 given.
- the movement of the control cam 88 is transmitted via the rollers 92 on the pivotable lever 100 and further via the coupling articulated rod 108 on the lower slide guide body 38.
- the lower winch tool 22 is thus also in a front and rear position in Relation to the wire exit point on the wire guide 16 by means of the cam gear 88, 92 and 100 moves.
- the winch tools 20 and 22 of the upper and lower winch apparatus 30 and 32 respectively doing so according to a constructively determined law (at least predominantly) at the same time postponed.
- the specially calculated curve laws of the two serve this purpose Control curves 68 and 88 in connection with the two program-controlled, intermittent forward and reverse rotating servomotors 64 and 86.
- control curve 88 in addition to two control sections, which are for the Initiation of tax movements in one or the other of the two Cam gears are designed over certain areas of their circumference with two Locking sections is provided, d. H. over this range of rotation of the curve of the Control curve 88 in each case there is no control movement on the transmission members.
- a coil spring to the right is the latching section of the control cam 88 for the upper one Winding device 30 responsible or effective, so here no swiveling movement around the Bolt 48 executes.
- the upper winch apparatus 30 is also rigidly fixed.
- the CNC-controllable servo motor 66 of the lower winch apparatus 32 is switched off programmatically. However, he can automatic bending of the first wire winding by the lower winding tool 22 be used.
- the servomotors 64 and 66 move the upper or lower winch tool 20 or 22 in the furthest from the wire guide 16 retracted, rearmost position, while then the servo motor 86 the control curve 88 continues to turn until the locking section of the control cam 88 is now for the lower one Winch 32 takes effect.
- the subsequent setting of the initial diameter of one Shaped spring or the outer diameter of a cylindrical coil spring is then carried out by switching on both servomotors 64 and 66, which the winch tools 22 and 24 move legally to each other to the extent necessary.
- the Drive motor 64 of the upper winch apparatus 30 switched off or for automatic Bending the wire of the first spring turn used by the upper winding tool 20.
- the coordinated movement required to produce a left-hand coiled form spring of the winch tool 20 of the upper winch apparatus 30 is carried out by the servo motor 86 driven control curve 88.
- the transmission of the movement of the control curve 88 now takes place via the two rollers 90 to the pivotable lever 98 and further via the coupling joint rod 106 and the bolts 110 and 114 onto the upper slide guide body 36, which thereby back and forth about the axis of the bolt 48 as a pivot center pivots and thus moves the winding tool 20.
- the linear movement of the lower winch tool 22 is carried out by the servo motor 66 driven cam 70 via the rollers 74 and the carriage 42.
- the winch tool 20 of the upper winch apparatus 30 is now used in the manufacture left-hand wound spring body as the inner tool and the winding tool 22 of the lower one Winch apparatus 32 as an external winch tool; while for right-wing Coil springs the upper tool 20 as the outer winding tool and the lower Tool 22 serves as an internal winding tool ("inside” and "outside” corresponding to the terminology reproduced in DE-OS 2 310 174).
- Winding tool 120 in two directions of movement as described below with reference to FIG Figures 1 to 7 is described in more detail.
- the only turning tool 120 is on a holder 122 on the carriage 40 of the upper one Winch apparatus 30 fastened, the carriage 40 via a cam 68 and on Batzen 76 seated rollers 72 is forcibly guided back and forth.
- Cam 68 itself is intermittently forward and by the program-controlled servo motor 64 (Fig. 7) driven backwards via the gear 60.
- linear and oblique directional movement is still a program-controlled swivel movement of the upper Carriage guide body 36 around the axis of the pin 48 as a pivot center (or can respectively).
- This swiveling movement is controlled by a CNC-controllable servo motor 86 Transfer transmission 84 to a cam 88 (as shown in FIG. 3) and from there via two Rollers 90 positively controlled on the lever 98 pivotable on pin 94 and further via a Coupling joint rod 106 on bolts 110 and 114 on a slide guide body 36 of the upper winch apparatus 30.
- the active surface of the winding tool 120 can be any Drive through the required course of movement.
- the lower one is for the production of left-hand coil springs in the one-finger winch system Winch 32 in use, while the upper winch 30 is now inactive.
- the rectilinear movement of the winch tool, not shown, is now carried out by the servo motor 66 from over the cam 70, and the pivoting movement of the lower Carriage guide body 38 around bolts 50 from servo motor 86, which is the control cam 88 previously rotated so far that the rest area is now for the upper inactive winch 30 is responsible, via this control curve 88 on the lever 100 and from here on the coupling link 108 on the slide guide body 38.
- left-handed coil springs can also be used with the winding tool 120 of the upper winch apparatus 30 are manufactured. All that is required is that the winch 30 of the servo motor 64 has been moved so far up that the winding tool 120 is now open the other side, ie above the wire guide axis 34 on the wire 14 and after works at the bottom, while for the previously coiled coil springs that Winding tool 120 engages on wire 14 below wire guide axis 34 and moves on moved up.
- the two winching apparatuses 30 and 32 arranged mirror-symmetrically to the wire guide axis 34 on the winch plate 26 and mirror-image to each other.
- the separate control of the Winding tools are also not made of circular coil springs, or it is possible to wind feather shapes that have different wind radii within one feather turn have.
