Definitions

  • rollers 1, 2, 3 are made of metal, these rollers tend to deflect as shown in Fig. 15 because of the pressure applied to the bearing 1a or 2a. So, it is impossible to clamp the workpiece between the rollers with an uniform pressure, so the workpiece tends to be cut off unintentionally. Further, the pressing by the hydraulic pump 8 against the bearing 1a or 2a can not be maintained always at a constant pressure, so the unbalanced pressure causes an unbalanced rolling as shown in Fig. 17.
  • one of the rollers 1, 2, 3 is an elastic roller, for instance, made of plastics or the like, its surface is easily scratched resulting in the degraded workpiece.
  • the plastic roller is not thermally resisted, when the workpiece is heated during the rolling process applying the heat to the metal roller with the steam or the line, the plastic roller is heated up resulting in the deterioration of roller and the shorter roller life.
  • some detecting means to detect the scratches in the workpieces is required, and also replacing the deteriorated roller with the new roller takes the considerable amount of times resulting in the higher manufacturing cost.
  • an uniform pressure is applied on the workpiece along the axial direction of the roller when the workpiece is pressed between the rollers, and a controllable magnetic force is applied to clamp and press the workpiece resulting in the trouble-free manufacturing and the easy maintenance.
  • a magnetic force is applied to attract the rollers such that a workpiece clamped and pressed between the rollers undergoes an uniform and predetermined pressure throughout the rolling process.
  • a yoke 26 is provided with solenoids 25 and with salient poles 26a which establishes the magnetic poles and with grooves 26b in which solenoids are accommodated.
  • the magnetic flux in the yoke 26 is shown in Fig. 7.
  • N-pole and S-pole are alternately established, and around the circumference of the yoke 26, N-pole or S-pole is established. In this drawing, N-pole is shown.
  • Two main rollers 36, 37 are placed in opposing relation and the distance between these two rollers are adapted to be adjusted.
  • Elactromagnets 38, 39 are disposed such that the attractive force between these two main rollers 36, 37 is established.
  • the main roller 36, 37 are made of magnetic material and are adapted to be moved in the direction of attractive force and rotatably supported by frame 40, 41 respectively.
  • One of the main rollers is driven by a belt 42 connected to a drive source 43.
  • the electric magnets 39, 39 are provided with yokes 44, 45 respectively which are fixed to the frame 40, 41.
  • the yokes 44, 45 are provided with solenoids 46, 47 respectively.
  • FIG. 12 the sixth embodiment of the present invention will be described.
  • Two middle rollers 50a, 50b of which material are magnetic are placed between main rollers 36, 37.
  • the constitution of the sixth embodiment is very similar to the fifth embodiment.
  • a workpiece 49 is inserted between the middle roller 50a and a main roller 37 and is drawn out finally being inserted between the middle roller 50a and a main roller 36.
  • solenoids 46, 47 energizes, the attractive force is established between the main rollers 36, 37 and between the middle roller 50a, 50b.
  • the main roller 36 is rotated by a belt connected to a motor 43, the workpiece 49 is advanced by the friction force established between the workpiece and the main roller.
  • the pressing force against the workpiece can be controlled by regulating the electric direct current to the solenoids 46, 47.
  • auxiliary rollers 51 are disposed between main rollers 36, 37.
  • the auxiliary rollers 51 are made of magnetic material. Increasing of numbers of auxiliary roller causes the magnetic force established between solenoids 46, 47 to be weakened. To strengthen the weakened magnetic force, auxiliary solenoids 52 are placed.
  • the auxiliary rollers 51 are rotatably supported by frames 53 and are adapted to be moved vertically.
  • the frames 53 are disposed between the main rollers 36, 37, and are adapted to be replaced. Providing yokes on the frame 53 or substituting the frame for the yoke, the auxiliary solenoids 52 can be eliminated.
  • the workpiece 49 is rolled by the main rollers and auxiliary rollers step by step being guided by guide rollers.
  • the workpiece 49 is advanced by the friction force established between the workpiece and the opposing roller.
  • the solenoids 46, 47 and the auxiliary solenoids 52 are used but these solenoids can be replaced by permanent magnets. According to the aforementioned embodiments, the presser rollers undergo the forced drive.
  • both main roller and pressure roller are made of metals
  • the workpiece is pressed between the main roller and the presser roller by the magnetic attractive force established therebetween, and the problem of shorter roller life is eliminated although the pressing force is considerably strong, and the frequency of exchanging rollers becomes less because the rollers are made of hard metals.
