Definitions
- the invention relates to a winch device for spring coiling machines with interchangeable, presettable elements.
- the applicability is given in one and two-finger winch systems in the manufacture of helical springs made of endless wire.
- the invention is based on the object of realizing interchangeable wind pin holders which can be preset outside the machine and in which the wind pin can be rotated in a controlled manner about its axis and moved in its longitudinal axis and perpendicular to it.
- it must be possible to pivot the longitudinal axis of the wind pins, which generally runs parallel to the direction of adjustment of the adjustment slides carrying the wind pin holders, into the negative or positive angular range.
- An adjustment device must make it possible to carry out the above-mentioned four settings outside of the machine on the basis of the values derived from the winch ratio and the wire thickness of the springs to be produced, whereby no undesired change may result from the installation in the machine.
- the wind pegs can be displaced in the longitudinal direction, controllably rotated and pivoted in a controlled manner by means of the wind peg holder and can be changed in height with respect to the adjusting slide, can be removed individually and can be preset in an adjusting device by means of the adjusting screws arranged on these elements outside the machine .
- the controlled twistable Windrichaufnähme is achieved in that adjusting screws are arranged on both sides of the axis of rotation, which are set against a reference surface. This reference surface is part of the wind pin holder carrying the wind pin holder. By setting one and opening the other set screw, the wind pins are twisted. The required working position of the wind pins is fixed by tightening both setscrews.
- This option is also used when presetting in the setting device outside the machine.
- the wind pin located in the wind pin holder is inserted into a suitable hole arranged in the measuring axis.
- the required rotation is achieved, which can be read on a measuring device.
- a screw is opened, the wind pin holder is removed, inserted into the wind pin holder and fixed in the required working position by tightening the same screw.
- the controlled pivoting movement of the wind pin holder is achieved using the same principle.
- the reference surface for this can be integrated directly into the bearing pin of the swivel axis or can be attached as an additional surface at another point on the adjustment slide.
- the only important thing here is the position of the set screws on both sides in relation to the swivel axis.
- the same procedure is followed when presetting the wind pin holder in the setting device.
- the reference surface for the set screws is not fixed here, but a Part of the rotatable swivel axis, the angular movement and thus the setting value indicates the measuring device.
- the positioning of the Windestifthal ter in the direction of the swivel axis is achieved by means of a spacing screw with which the distance to the adjustment slide level is adjusted according to the wire thicknesses to be processed and the desired pretension.
- the setting is also carried out in the setting device by means of a suitable length measuring device. This is also used for the length adjustment of the wind pins, the wind pin receptacles being accommodated in a sleeve which can be adjusted in the longitudinal direction.
- the wind pin holder is attached to the adjustment slides by screwing, the spacer screw serving as an end stop. If a screw is powerful enough, a threaded hole in the swivel axis is advantageous.
- round, square and rectangular coiling pins can be used with the appropriate design of the coaster holder.
- the coiled pin holders are expediently designed in such a way that inserts similar to inserts can be screwed on.
- the measuring device of the adjusting device can be designed mechanically or electronically.
- the rotary movement of the measuring axis is transmitted via a lever linkage to an analogue indicating protractor, while the longitudinal adjustment is carried out via fixed stops or by means of a dial gauge.
- an angle encoder would be attached to the measuring axis, the impulses of which would be made visible on a display of a display device.
- Fig. 1 shows an embodiment of a two-finger winch system with integrated in the pivot axis reference surface, a wind pin holder is shown in section AB
- Fig. 2 shows an embodiment of a single-finger winch system with an external reference surface and an insert-like winch tool
- Fig. 3 shows an embodiment with a directly mounted round wind pin with slid-over adjustment sleeve
- Fig. 4 shows an embodiment of a setting device for presetting with a mechanical display, the side view showing the twisting of a wind pin holder and the length setting of the wind pin, while the top view shows the setting of a wind pin holder.
- the wind pin holders 13/14 are provided with a square hole 15.
- As a wind pin 16 is a rectangular. Cross section with supplement 17 used. Clamp with screw 18 and longitudinal adjustment with screw 19.
- the screws 20/21, which are supported against the surface 22, are used for controlled twisting.
- FIG. 2 shows an embodiment in which a turning tool similar to an insert with a hexagonal hard metal piece 24 is used.
- the adjusting slide 25 is provided with an external reference surface 26 for the controlled pivoting movement which is achieved with the screws 27/28.
- the wind pin holder 29 is designed so that these screws engage on both sides of the pivot axis 30.
- the cuff 32 is attached at the end. It contains the two screws 33/34 required for controlled turning, a clamping screw 35 and a screw 36 for longitudinal adjustment. With the small forces occurring here, it is sufficient if the feet 37 of the square screws 33/34 are supported in a groove 38 in the reference surface 39.
- the adjusting device for presetting consists of a base plate 40 in which a bolt 41 serving as a measuring axis is rotatably mounted.
- the rotary movement of this bolt is transmitted via a lever linkage 42/43/44 to an analog mechanical protractor 45, which is secured against rotation with the tab 46 on the base plate.
- the wind pin holder 10 is pushed from above over the bolt 41 in such a way that its boundary furthest away from the measuring axis lies against the bar 47, while the mirror-image wind pin holder 9 is allowed to rest on the opposite bar 48. This ensures a position that prevents rotation.
- the bolt 41 is formed at its upper end so that a reference surface 49 is provided for the screws 7/8 provided for the controlled pivoting movement. By properly adjusting these screws, the bolt 41 is rotated clockwise or counterclockwise, which can be read on the protractor 45.
- a square hole 50 which serves as a receptacle for the wind pins 16 located in the wind pin receptacles 13/14.
- a plate 52 which can be inserted into the slot 51 of the base plate provides the reference surface for those used for controlled rotation
- the adjusting device has a dial gauge 55 which can be pivoted into the measuring position on a bracket 53 around the axis 54.
- the height adjustment of the wind pin holder 9/10 takes place with the help of the dial gauge 55 in the same position as in the controlled adjustment of the pivoting movement.
- the pintle receptacles 13/14 are inserted into a special sleeve 56 which is adjustable in the longitudinal direction.
