Definitions

  • the invention relates firstly to a wire-drawing apparatus, having a cover, with a drawing-disk drum with cooling being disposed above the cover, and a drawing-disk drum drive motor and supply and discharge lines for the cooling also being provided.
  • the invention relates to a drawing-disk drum for a wire-drawing apparatus, having a drawing-disk drum drive motor, which is connected coaxially to the drawing-disk drum without the intervention of any transmission mechanism, and a cooling device with supply lines appertaining to the inlet and outlet.
  • a wire-drawing apparatus equipped with drawing-disk drums of this type, in a straight-draw version, is disclosed by the Koch brochure “MIn für die Drahtindustrie” [Machines for the Wire Industry], 2.98.
  • the drawing-disk drums are each assigned a transmission mechanism in their underfloor region.
  • the transmission mechanism is connected to in each case a laterally mounted drive motor via V-belts as transmission means.
  • the drive motor is mounted adjustably on a supporting wall of the wire-drawing apparatus. This limits the space available for accommodating the required supply and discharge lines, extraction pipes for drawing powder, etc. and also the accessibility thereof for maintenance purposes to a considerable extent and, moreover, affects the overall height of the installation.
  • German published patent specification 25 53 215 has disclosed further details on the drawing-disk drum and wire-drawing apparatus, such as a liquid-carrying internal cooling system and cooling-air-carrying external cooling system.
  • the above object is achieved firstly and substantially by the subject matter of claim 1 , in which it is provided that the supply lines are routed through the drawing-disk drum drive motor, which is configured as a synchronous electric motor.
  • the drawing-disk drum drive motor disposed beneath the cover which represents a fundamental horizontal division in the wire-drawing apparatus of the type under consideration here is disposed in such a manner that supply and discharge lines are accommodated on both sides, namely the operating side and the rear side, of the apparatus. Disposing the drawing-disk drum drive motor such that it is connected coaxially and without the intervention of any transmission mechanism results in a significantly improved overall arrangement of the wire-drawing apparatus.
  • the supply lines are routed straight through the drawing-disk drum drive motor. They may even, as is disclosed in more detail below, under certain circumstances be routed straight through the rotor of the drawing-disk drum drive motor, the said rotor being formed as a hollow shaft. On the other hand, it may also be a solid shaft with suitable bores or passages.
  • a synchronous motor as discussed here is commercially available and operates reliably within the required power ranges. The result is a more compact overall structure. This gives a gain in space not only for the abovementioned lateral regions but also for the underfloor region itself, including with regard to a required drawing-powder extraction apparatus. The overall height of the wire-drawing apparatus is reduced. This significantly facilitates measures such as the rewelding of torn wires.
  • the drawing-disk drum is advantageous for the drawing-disk drum to be driven by means of a disk head flanged onto the synchronous motor. It has proven structurally expedient for the disk head to be flanged onto the rotor of the synchronous motor by means of a neck bearing. Furthermore, an advantageous feature involves the synchronous motor, at least in part, being flanged on with a radial overlap with the drawing-disk drum. A solution which is of even independent importance furthermore results from the drawing-disk drum being in pot-like form in cross section, with a pot base facing the synchronous motor. This results in a structure which is open at the top but can optionally be closed off by an inspection cover.
  • the inspection cover which provides protection in practice, can be removed as necessary, so that functional parts accommodated in the pot space are readily and quickly accessible. By way of example, it is in this way straightforward to exchange wearing parts.
  • the pot base can then perform an additional function by simultaneously serving to transmit the driving torque from the synchronous motor to the drawing-disk drum. This means that it performs a flange function.
  • the pot base may simultaneously be the carrier for at least parts of a cooling apparatus, which preferably has a closed coolant circuit.
  • the connection to a supply source may be via the rotor if the rotor of the synchronous motor is configured as a hollow shaft. Accordingly, supply lines for the cooling apparatus can be routed through the axially central cavity in the hollow shaft.
  • a particularly space-saving solution is obtained if the synchronous motor extends as far as into the interior of the pot-like drawing-disk drum.
  • a motor body of this type partially withdrawn into the drawing-disk drum, can in this case perform the function of a central reinforcing core for the relatively thin-walled drawing-disk drum.
  • FIG. 1 shows a highly schematic illustration of the drawing-disk drum in vertical section with a synchronous motor docked onto the underside, in accordance with the basic version
  • FIG. 2 shows an illustration corresponding to FIG. 1 using a neck bearing, embodying a first variant
  • FIG. 3 shows, in the same form of illustration as FIG. 2 , a second variant, in which the synchronous motor is partially withdrawn into the pot space of the drawing-disk drum,
  • FIG. 4 shows an isolated, perspective illustration of the synchronous electric motor.
  • the drawing-disk drum 1 illustrated is disposed in an aperture region 2 of a wire-drawing apparatus 3 .
  • the aperture region 2 is located in a cover 4 of a bed 5 of the wire-drawing apparatus 3 which has a plurality of drawing stations.
  • a base carrier 6 represents the connecting part and has a peripheral flange 7 . The latter engages over the upper edge of the hole formed by the aperture region 2 , where it is fixed in place.
  • the securing location is denoted by reference numeral 8 .
  • This may be a screw crown.
  • the drawing-disk drum 1 positioned above the cover 4 is set in stepless rotation and braked by a drawing-disk drum drive motor 9 disposed beneath the cover 4 .
  • the rotation takes place about a geometric axis x-x.
  • the axis x-x may be vertically oriented.
  • An inclination in the wire-drawing direction is preferred.
  • an inclination toward the front may also be incorporated.
  • the front means an operating side 10 of the system.
  • the drawing-disk drum drive motor 9 is formed as a synchronous electric motor. It has no transmission mechanism and is connected to the drawing-disk drum 1 . According to the basic version, this connection is produced in the region of the cover 4 or of the base carrier 6 .
  • the securing location is denoted by 11 and connects the rotating part of the synchronous motor, i.e. the rotor 12 to the drawing-disk drum 1 , which is pot-shaped in design. On the securing side, this drum is terminated by a pot base 13 .
  • a rotor flange 14 which is in the form of an annular disk and passes freely through an opening 15 in the base carrier 6 , extends on the underside of this pot base.
  • the abovementioned securing location 11 is formed between the pot base 13 and the rotor flange 14 .
  • the stator 16 of the synchronous electric motor is fixedly connected to the base carrier 6 .
  • the securing location in this respect is denoted by reference numeral 17 and once again comprises a screw crown.
  • the bearing of the drawing-disk drum 1 is realized by the synchronous motor by the drum being directly connected to the rotor 12 of the motor.
  • the bearing means of the synchronous motor are generally configured suitably for the corresponding power range. If the conventional features do not suffice, it is appropriate for the bearing of the rotor 12 of the synchronous motor to be reinforced with a view to simultaneous bearing support of the drawing-disk drum 1 . In this context, it is advantageous for the pot base 13 simultaneously to serve to transmit, over the shortest possible path, the driving torque from the synchronous motor to the drawing-disk drum 1 .
  • the pot base 13 merges into the substantially cylindrical pot wall 18 , which is fitted to a peripheral annular step 19 of the pot base 13 .
  • the corresponding end is thickened and, moreover, is surrounded by a free-standing annular collar 20 of the base carrier 6 .
  • a wind-on location 21 for the wire close to the bottom.
  • This is a rotationally symmetrical cone flank, formed in part by the end of the annular collar 20 and in part by said thickened portion, which is oriented radially outward.
  • a wire coil is built up here starting from the bottom and continuing as far as a wind-off location at the top on the drawing-disk drum 1 .
  • the synchronous motor is flanged on, at least with a partial radial overlap with the drawing-disk drum 1 .
  • the cross section of the synchronous motor shown in the drawing is in reality slightly set back with respect to the pot-shaped cross section of the drawing-disk drum 1 . This too results in a sufficient docking area.
  • the general use of a synchronous electric motor and its compact association with the drawing-disk drum 1 create provisions serving to provide free space 23 for the various supply and discharge lines for the cooling and also for an extraction pipe for the drawing powder produced both in the underfloor region and on both sides, i.e. on the operating side 10 and the rear side 22 . Moreover, the overall height of the system can be reduced.
  • the rear side 22 is delimited by a wall 24 of the wire-drawing apparatus 3 .
  • the drawing-disk drum 1 has a liquid-carrying internal cooling system, referred to as cooling apparatus 25 , which comprises a chambered annular gap 26 which is supplied via an inlet 27 and an outlet 28 .
  • cooling apparatus 25 which comprises a chambered annular gap 26 which is supplied via an inlet 27 and an outlet 28 .
  • the means which partition off the annular gap 26 with respect to the pot interior 29 are conventional and require no further explanation here, except to say that the cooling apparatus 25 has a closed coolant circuit.
  • the precedent cited above by contrast, involves the technique of the cooling apparatus 25 leaving an open gap of reduced cross section with respect to the annular gap to allow the coolant to flow away and be collected in a channel 30 . This configuration is put into practice in the first variant ( FIG. 2 ) and may also be provided for the second variant ( FIG. 3 ).
  • the pot base 13 is the carrier for at least parts of the cooling apparatus 25 , which are formed on the base side as centrally located rotary leadthroughs 31 , 32 , connected to the abovementioned wall-side inlet 27 and outlet 28 , respectively.
  • the latter are provided in a number corresponding to the number of annular gaps 26 or chambers and rotate therewith.
  • Supply is effected from the underfloor region. Reference is made to connection 33 at that location. From there, supply lines lead to the cooling apparatus 25 , running through the axially central cavity 34 of the rotor 12 , which is configured as a hollow shaft.
  • the corresponding hollow-shaft motor can be seen clearly from FIG. 4 .
  • the pot interior 29 which is open at the top, of the drawing-disk drum 1 offers access which is favorable for mounting purposes and for maintenance.
  • the opening can be closed by an inspection cover 35 .
  • FIG. 2 in terms of motorization, this is in principle of the same structure.
  • the reference numerals are transferred accordingly, where required to provide a better understanding, in some cases without the associated text being repeated.
  • the drawing-disk drum 1 is driven by means of a disk head 36 flanged onto the synchronous motor, i.e. from above.
  • This disk head is connected to the rotor 12 of the synchronous motor via a central neck bearing 37 .
  • the rotor flange 14 of the rotor 12 continues centrally in the pot interior 29 , as shaft piece 38 , toward the disk head 36 .
  • a central connection piece 39 debouches in the opposite direction and is fixedly seated, in a cone-centered and screw-connected manner, on the shaft piece 38 .
  • the connection of the disk head 36 toward the pot wall 18 of the drawing-disk drum 1 is effected by means of a securing location 40 , which may likewise be realized as a screw crown.
  • An inner, upwardly directed annular wall 41 of the base carrier 6 in this case represents the pot-internal closure of the annular gap 26 of the cooling apparatus 25 .
  • the base carrier 6 merges, in an outward direction, into a molded protuberance 42 , which partly forms the channel 30 and at which the lower end of the substantially cylindrical pot wall 18 of the drawing-disk drum 1 is rotationally guided.
  • the second variant differs from the subject matter explained above in structural terms by virtue of the fact that the synchronous motor extends into the pot interior 29 of the drawing-disk drum 1 , using approximately half the vertical height of the pot interior 29 .
  • the corresponding overlap with the upwardly extending annular wall 41 allows the outer contour of the synchronous motor of matching cross section to function as a central supporting core.
  • the annular wall 41 continues upward in the manner illustrated in FIG. 2 . Insertion is limited by an inwardly directed, horizontal annular shoulder 43 , at which is located the securing location 17 with respect to the stator 16 .
  • the rotor connection is the same as has been outlined in connection with FIG. 2 .
  • the wire tension is self-regulating, which is effected by means of a dancing-roll control.
  • the information can be correspondingly taken off at a bend zone of the wire, functioning as a transmitter, such as results at the wind-off location close to the top of the drawing-disk drum 1 , and this information can be converted into control pulses for the synchronous motor. In this way, the rotational speeds of the drums which increase from station to station as a result of the wire becoming thinner are brought about accurately, i.e. the appropriate drawing-disk speed is set.
