Definitions

  • This invention has for object a rolling-mill for high reductions.
  • the scope of the present invention is to render possible and advantageous the planetary rolling in the mills for long products, that require the rolling both with horizontal and vertical axis.
  • this type of plant can substantially be called star mill for the specific star conformation of the support structure of the respective peripherical rolling-mill rollers (satellites rolling-mill rollers in a loadbearing solar wheel conformed substantially in a star shape).
  • the machine consists therefore of four rolling-mill groups (four solar wheels in opposite couples identical and symmetric) which peripherical satellite rollers of each torque act alternatively according to the vertical axis and horizontal axis.
  • Every solar wheel therefore supports a series of rolling-mill rollers mounted planetarly on an structure put into rotation that is said solar wheel (star structure).
  • the minimum number of rolling-mill rollers (known also with the definition cylinders) mounted on every structure is one, but advantageously there can be more (for example four or more).
  • the rotation of the planetary wheels is ensured by known means (motors/reductors) and can rotate in both directions in discordance or in agreement with the advancement of the material being rolled.
  • Satellites rolling-mill rollers will rotate in both directions in discordance or in agreement.
  • Figure 1 is a frontal schematic view of a universal rolling holster with two couples of opposite planetary rolling wheels, each conformed in a star shape and bearing four rolling-mill rollers with perfectly synchronized and staggered rotation of half pitch.
  • Figure 2 represents, a schematic side section view.
  • Figures 3, 4, 5 ,6, represent in respective side views and in section AA, BB, CC, DD the progressive reduction form of the laminate to obtain, square, round, "L", and double "T".
  • the rotation of the planetary wheels is perfectly synchronized by means of mechanical transmission.
  • the machine represented illustrates a functioning with four planetary wheels put into rotation in agreement with the laminate.
  • the planetary wheels are indicated respectively with 1,2,3,4.
  • Each planetary wheel includes a solar wheel made from two star plates S1-S2, and between these star plates four idle satellites rolling-mill rollers "r" are supported.
  • the four planetary wheels 1,2,3,4 lie with the coplanar rotation axis on orthogonal plane to the advancement line of the laminate "L".
  • Towards the top of the rolling-mill holster can be provided either a towing system "T”, or a prelamination system, or a straightening system, as from known technique.
  • T towing system
  • prelamination system prelamination system
  • straightening system straightening system
  • the four planetary wheels 1,2,3,4 are contained in a case 5 and everything is supported by a loadbearing structure 6.
  • the rotation of the four planetary wheels is performed by a single motor axis 14, the tractor gear 13 of which transmits the motion to two opposite gears 12 and 27.
  • the gear 12 transmits the motion via 11
  • cardanic articulation 10 transmits the rotary motion to the planetary wheel 1 of which the star plates holding the satellites s1, s2 are distanced by an axial spacer 10'.
  • the opposite planetary wheel 2 is commanded at the same speed and same angular value, by wheel 27 via joint 26, joint 24, gears 23-22-21 and cardanic articulation 20, in order that the opposite rollers "r" coincide perfectly with each other in the respective opposite symmetric movement.
  • Planetary wheel 3 receives the motion from cardanic articulation 30 that connects to the conic group 25 from one side and the planetary wheel 4 receives the motion from the articulation 40 via conic couple 41, joint 42 and gears 43-44, this last one geared to 11 of the first transmission.
  • the ratios of transmission will be, as said, duly calculated to supply the desired synchronism.
  • the rolling rollers rotate in a discordant way respect to the bar subjected to the rolling "L", but because the speed of the planetary wheel is greater than the advancement speed of the laminate, it results that the couple of rollers "r" (horizontal and vertical) that alternatively come into contact with the material, each produce a small rolling action.
  • This rolling-mill (horizontal, vertical) allows the contemporary rolling on all the surface of the material, this means that any form of laminate can be laminated (with a high reduction system).
  • the rolling rollers can be motorized on their own or can also be idle as in the specific case reported in the figures.
  • each couple of opposite planetary wheels is call planetary couple 1-2 and 3-4; each rolling roller is called planetary rolling roller and the wheel that supports them is called solar wheel.
