Definitions
- An object of the invention is a winch device according to the preamble of claim 1 for spring winding machines.
- Another object of the invention is, according to the preamble of claim 8, an adjusting device for presetting adjusting screws of the winch device.
- 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 adjustment direction 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. Since spring steel wires can fluctuate in their hardness and thus in their spring-back behavior, a controlled readjustment in the machine must be possible.
- a winch device according to the preamble of claim 1 was previously known.
- the wind pin holder is controlled by one by means of adjusting screws which interact with the wind pin holder and are mounted on this holder Tilt axis rotatable, which is mounted on the wind pin holder and crosses the longitudinal axis of the received wind pin vertically skewed. This possibility of rotation is not absolutely necessary.
- the swivel axis of the wind pin holder intersects the longitudinal axis of the held wind pin vertically.
- An adjusting screw which is mounted on the tool holder parallel to the longitudinal axis of the bolt and is supported on the setting slide, is missing.
- By means of the two adjusting screws for tilting the tool holder it is not possible to adjust the height position of the winch tool with respect to its adjusting slide by displacing the winch holder along the pivot axis by means of an adjusting screw.
- a second pair of set screws is also missing, which is supported on both sides of the swivel axis of the tool holder on a slide-proof device part.
- the set screws of each unit for rotating or pivoting a wind pin on a surface rigidly connected to the associated wind pin holder or adjusting slide on different sides of the axis of rotation (longitudinal axis of the Support wind pin) or swivel axis.
- the controllably rotatable wind pin holder 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.
- Another object of the invention is, as indicated, an adjusting device for presetting adjusting screws of the preferred embodiments of the winch device according to the invention.
- This adjusting device is characterized in accordance with claim 8 by its characteristic features.
- a further developed adjustment device for the first and second structural unit with adjusting screws of the winch device according to claim 4 is characterized by its characteristic features.
- this setting device is provided with an axis which is perpendicular to the base plate and on which a plate-parallel bracket with a length gauge (dial gauge) is axially displaceable
- the bracket is pivotable about the axis, until the length measuring device stands above a tool holder which is arranged on the plate-fixed bolt in a rotationally fixed manner; and that the base plate in the swivel range the boom contains a sleeve for storing a tool holder with the tool picked up in a vertical position.
- a "device for pre-setting the tools on a tool holder” this is attached to the head of a spindle, which is mounted in a bushing attached to the base plate is mounted so that the tool holder is rotatably arranged with respect to the plate-fixed sleeve.
- the base plate contains another bush for the rotary mounting of a spindle in a vertical position, which receives a stop drum which interacts with the tool holder, the stops of which can also be adjusted in advance by means of the device, can be reached one after the other by a second length meter on a second boom, which is just as little the first boom can be pivoted about the axis perpendicular to the base plate.
- the dowel pin located in the dowel pin 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 removed, inserted into the wind pin holder and fixed in the required working position by tightening the same screw.
- 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 wind pin holder in the direction of the swivel axis is achieved by means of a spacer screw, with which the distance to the adjustment slide level is adjusted according to the wire thickness to be processed and the desired pretension.
- the setting is also carried out in the setting device by 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 sufficient for this purpose, a threaded hole in the swivel axis is advantageous.
- coiler pins In the case of small and medium-sized spring coiling machines, round, square and rectangular coiling pins can be used with the appropriate design of the coaster holder. In the case of large spring coiling machines, on which thick wires are processed, the coiler pins are expediently designed in such a way that inserts similar to inserts can be screwed on.
- the measuring device of the setting 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 angular step encoder would be attached to the measuring axis, the impulses of which would be made visible on a display of a display device.
- the wind pin holders 13/14 are provided with a square hole 15.
- a rectangular cross section with an insert 17 is used as the wind pin 16.
- 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 indexable 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 When a round wind pin 31 is directly supported, the cuff 32 is attached at the end. It contains the two screws 33/34 necessary for the controlled turning, a clamping screw 35 and a screw 36 for the 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. is attached.
- 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 there is a reference surface 49 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.
- the adjusting device has a dial gauge 55 which can be pivoted about the axis 54 into the measuring position on a bracket 53.
- 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 swiveling movement.
- the pintle receptacles 13/14 are inserted into a special sleeve 56 which is adjustable in the longitudinal direction.
