Definitions

  • This invention relates to a straightening machine which comprises adjustable upper rolls and which is mainly intended for straightening spliced strip metal.
  • strip sections of larger or smaller length are overlapped and joined by spot welding to ensure a continuous feeding of the strip.
  • This is also required for metal strip which is finished by a passage through baths, such as tin or zinc baths.
  • the strip straightening machines which are included in such strip treating lines had previously to be opened before the approach of these varied riveted lap joints and after the passage of said joints the machine had to be reset to the nip required for straightening. This adjustment was effected with the aid of a positioning motor. An operator is required for controlling this operation and must also adjust the pressure required for straightening. During the slow lifting and lowering of the set of upper rolls, a great length of strip passes without being straightened. These strip lengths cannot be used.
  • the straightening pressure can be readjusted in the usual manner by means of the positioning motor and independently of the high-speed stroke.
  • the thrust screws for the set of upper rolls comprise, in known manner, worm wheels mounted on splined shafts and are mounted in the machine frame in nuts so that they are adjustable by a rotation.
  • these nuts are rotatably mounted in the frame and provided with a pinion rim so that they can be driven by a meshing rack for a high-speed adjustment.
  • the splined shaft prevents a rotation of the thrust screws subjected to said high-speed adjustment.
  • the thrust screws for the upper rolls may be adjustable in known manner by a positioning motor through worm gearing and may be capable of a high-speed adjustment by means of the nuts which are mounted in the machine frame and provided with a pinion rim in mesh with a rack.
  • the pinion rims lie on one side or on both sides of a common rack, which is preferably hydraulically operated.
  • FIG. 1 is an elevation showing a straightening machine according to the invention
  • FIG. 2 is an enlarged fragmentary elevation showing a portion of the embodiment of FIG. 1.
  • the straightening machine comprises a machine frame 1, which supports the sets of upper and lower rolls 2 and 3.
  • the set of the upper rolls 2 is vertically adjustable by the positioning motor 5 by means of a worm gearing 6 and thrust screws 4 to set the roll nip and straightening pressure.
  • the thrust screws 4 are mounted in the machine frame 1 by means of rotatable nuts 7, which carry pinion rims 8.
  • the pinion rims 8 are adjusted by a rack 9, which is, e.g., hydraulically driven. This results in a high-speed stroke of the set of upper rolls 2, which are connected by the bearing body 10 to the thrust screws 4.
  • the feelers 11, 12 control by electric means the operation of the hydraulic rams.
  • a photoelectric control may be provided.
  • the metal strip is punched before the riveted joint, or a light control is used which employs rays and responds to the increase in the thickness of the strip.
  • the continuous rack engages the same On the same side. If the set of upper rolls is operated by four thrust screws, each side of the rack is suitably in mesh with two pinion rims for driving such screws.
  • each nut is formed with a pinion rim
  • said nut drive means comprise a single rack in mesh with the pinion rim of each nut and hydraulic means for driving said rack.
  • said screw drive means comprise a positioning motor and transmission means between said motor and said thrust screw.
