Definitions

  • Keenan Attorney-Cushman, Darby & Cushman [57] ABSTRACT There is provided an arrangement in storage type wire drawing machines for continuously and automatically controlling the speed of an individually driven drawing block having an associated guide block arranged coaxially therewith and a guide pulley arranged between the blocks, which guide pulley is mounted for rotation on a support means journalled between the blocks and being capable of pivoting relative to the blocks. The pivoting movements of the support means are used to control the speed of rotation of the driven drawing block.
  • the arrangement also includes a machine element which is securely mounted between the blocks on a depending journal pin or shaft over the drawing block and supports transmission means adapted to transmit the pivoting movements of the support means to a device which transmits a signal in response to said pivoting movements to the motor driving the block, thereby to change the speed at which the block rotates.
  • the present invention relates to an arrangement in storage type wire drawing machines for continuously controlling the speed of an individually driven drawing block having an associated guide block arranged coaxially therewith and a guide pulley arranged between the blocks, which guide pulley is mounted for rotation on a support means journalled between the blocks, the support means, in turn, being capable of pivoting in relation to the blocks and the pivoting movements of which are used to control the speed of the driven drawing block.
  • the known guide means In addition to being incapable of uniformly cooling the wire, the known guide means also render it impossible to utilize programme control systems to control the guide block in relation to the drawing block in a manner to obtain a suitable height of wire on the block.
  • the object of the present invention is to eliminate these disadvantages and to provide an arrangement which is capable of continuously guiding the wire onto and off the guide block in a manner such that in addition to the wire being coiled smoothly to a suitable height on the block and cooled in a controlled manner, it also enables the various operations to be controlled by the programme systems.
  • the significance of this will be readily perceived, since among other things the pur pose of the guide block is to deliver or store wire for a limited period of time in the event of a break-down in the wire drawing machine or the associated coiling mechanism, so that the process may continue without interruption for as long as possible.
  • the arrangement of the present invention in addition to fulfilling the aforementioned requirements also favourably affects the production output rate, since it renders stopping and starting of separate blocks for controlling the height of the wire stored on the blocks unnecessary, and is mainly characterized in that it includes a machine element which is securely mounted between the blocks on a shaft journal arranged to hang downwardly from above the drawing block and to support a transmission means adapted to transmit the pivoting movements of the support means to a device which transmits a signal corresponding to the pivoting angle in order to provide for a corresponding, compensatory change in the speed of the driven drawing block.
  • a rotatable drawing block 1 is mounted on a vertical shaft 2.
  • the shaft is journalled to a lower frame structure 3, for example at 4 and 5.
  • the drawing block is driven by a worm gear 6 mounted on the shaft 2 and the worm gear 6 is arranged to mesh with a worm screw 7 journalled in the lower frame structure and driven by a DC. motor (not shown), which serves to drive the unit'individually.
  • the lower frame structure 3 also supports a panel 8, on which are arranged the instruments and control devices required for operating the unit and the arrangement according to the invention.
  • a drumlike guide block 11 mounted for rotation on the upper portion of the stationary journal pin or shaft, for example at 12 and 13, is a drumlike guide block 11.
  • a drum-like member 14 which is journalled for rotation on the depending stationary journal pin or shaft, for example at 15 and 16.
  • the member 14 which hereinafter is called the support means, carries on an external surface thereof a guide pulley 16 which receives the wire running from the drawing block 1 to the guide block 11.
  • a transmission means 17 Securely attached to the support means 14 internally thereof is a transmission means 17 which is mounted concentrically around the depending journal pin or shaft 9 and which in the exemplary embodiment is in the form of a belt pulley.
  • the transmission means may be in the form of a V-belt pulley, a gear or the like.
  • a drum-like element 18 Securely attached to the free end of the depending, stationary journal pin or shaft 9 and located beneath the support means 14 but spaced therefrom is a drum-like element 18.
  • the element 18 is located immediately above the drawing block 1 and is coaxial therewith but spaced therefrom.
  • the guide pulley 16 is arranged between the drawing block 1 and the guide block 11 and is supported by the support means 14, on which it is journalled for rotation.
  • the support means 14 is capable of pivoting relative to the two blocks, with which it is coaxially arranged.
  • the arrangement according to the invention automatically balances the system, insomuch that the movements of the support means which are directly proportional to the speed differential between the blocks and thus also to the speed at which the wire is coiled thereon and uncoiled therefrom, is used to regulate the speed of the drawing block.
  • This is effected in accordance with the invention by means of a transmission means which transmits the pivoting movements of the support means 14 to an angle detector 19 which in turn transmits signals corresponding to the pivoting movements of the support means 14 for the purpose of providing corresponding, compensatory changes in speed of the driven drawing block.
  • the angle detector 19 comprises an electrical transducer, for example a transducer of the type commercially known as elgon transducer.
  • the transducer is mounted in a manner such that one active portion thereof is secured to a portion of the lower frame structure 3, for example the stationary bearing block 20.
  • the other active portion of the transducer is secured to a shaft 21 which is mounted for rotation in the shaft 2 supporting the drawing block 1.
  • the shaft 21 is arranged to project from the upper end of the shaft 2 and carries a device corresponding in form to the transmission device 17, for example in the form of a belt pulley 22.
  • the angle indicator 19 may comprise, for example, a rotary potentiometer or some other suitable means capable of transmitting a signal corresponding to the magnitude of the swinging movement of the support means 14, for the purpose of providing a change in speed of the motor and/or the block compensatory to the movement of the supporting means.
  • a mechanical type of angle indicator for controlling the speed of the drawing block and thus a mechanical variator can be used, for example.
  • the transmission means for transmitting the pivoting movements of the supporting means 14 on the stationary journal pin or shaft 9 to the angle indicator 19 comprises, in addition to the mentioned transmission devices or belt pulleys 17, 22, the element 18 which is securely mounted to the stationary journal pin or shaft 9.
  • Mounted for rotation in a sleeve 23 securely attached to the element 18 is a shaft whose ends project out from the sleeve on either side of the element 18.
  • the outwardly projecting ends of the shaft, which project into the interior of the support means 14 and the drawing block 1 each carry a device, for example the belt pulleys 24, 25, corresponding to the transmission devices 17 and 22.
  • a belt 26 passes around the upper pulley 24 of the pulleys mounted on the shaft journalled in the sleeve 23 and the pulley 17 mounted in the support means 14, while a second belt 27 passes around the pulley 22 connected to the angle indicator 19 via the shaft 21 and the lower pulley 25 of the pulleys mounted on the shaft journalled in the sleeve 23.
  • An arrangement in storage type wire drawing machines for continuously controlling the speed of an individually driven drawing block comprising:
  • a support means journalled between the drawing and guide blocks and being capable of pivoting movements therebetween in response to relative differences in rotational speed between the drawing and guide blocks;
  • a guide pulley is arranged between the drawing and guide blocks, said guide pulley is mounted for rotation on the support means;
  • transmission means supported by said shaft journal means for transmitting a signal that corresponds to an angle formed by the pivoting movement of the support means
  • a shaft is mounted for rotation in the machine element, a'first means supported by one end of the shaft, a first corresponding co-operating means which with said first means is in movement transmitting connection with the support means, a second means which is supported at the other end of the shaft and a second corresponding co-operating means, said second means and said second corresponding co-operating means are in movement transmitting connection with the device.
