Definitions

  • the invention relates to the general field of shearing and in particular to the shearing of metal plates and strips.
  • the present invention is concerned with improvements to apparatus and methods for employing the rocking type shearing action.
  • the invention addresses these problem of the prior art by providing, according to a first aspect of the invention, a metal shearer comprising the features recited in claim 1 attached hereto.
  • a method of shearing metal comprises the steps set out in claim 9 attached hereto.
  • Figure 1 is a schematic representation of a conventional rolling cut mechanical shear, employing cranks to control the rolling cut motion of the shear;
  • figure 2 is a schematic representation of a hydraulically operated rolling cut shear
  • figure 3 shows the error between the ideal lateral position of the upper blade (for a perfect rolling cut) and the actual position when the upper blade is constrained by a side link of fixed length and
  • figure 4 shows a schematic representation of a rolling cut shear according to the invention.
  • the figures are not to scale and are not intended to represent the relative sizes of components. Any component which appears in more than one figure is lablelled with the same numeral throughout.
  • a conventional rolling cut mechanical shear comprises an upper blade 1 and a lower blade 2 mounted on a support beams 3 and 4 respectively.
  • the rolling cut motion of upper blade is determined by cranks 5 and side link 6.
  • the fixed length of side link 6 prevents the upper blade 1 (and associated support beam 3) from executing a perfect rolling action. Instead, a degree of lateral movement of blade 1 with respect to the object being cut is caused.
  • Figure 3 plots the error between the ideal lateral position of the blade for a perfect rolling cut and the actual position as a result of the fixed length link. In practice, typical errors range from about -20mm to +30mm.
  • the fixed length side link is replaced with link of variable length 9.
  • the variable length link is realised as a hydraulic cylinder.
  • the stroke of the hydraulic cylinder is controlled by a servo-valve 10 and an electronic control system 11.
  • a position transducer (not shown) which is mounted on cylinder measures its stroke and the control system 11 adjusts the stroke to the desired value by sending an appropriate signal to the servo valve.
  • the reference stroke for the cylinder is adjusted during the rolling cut motion in synchronisation with the movement of the upper blade in order to achieve a good rolling cut action with minimal lateral movement of the upper blade relative to the sheet being cut.
  • Electronic control system can be realised as a computer programmed to send the necessary signals to servo valve 10, in response to varying position of the support beam 3 and the stroke of cylinder 9.
  • variable length link 9 could be realised as a screw jack (e.g. an electrically driven screw jack) or an eccentric cam.
  • screw jack e.g. an electrically driven screw jack
  • eccentric cam e.g. an eccentric cam
  • a hydraulic cylinder to provide the variable length link may be particularly suited to systems employing hydraulic cylinders elsewhere (for example the system of figure 4), and which include the necessary elements of a hydraulic system anyway.
  • a prior art system employing such cylinders e.g. figure 2) particlurly lends itself to a post market upgrade, employing a further cylinder and associated control equipment to create a system such as that illustrated by figure 4.

Abstract

L'invention concerne un dispositif de cisaillement de métal, dans lequel la bielle latérale fixe qui est normalement utilisée pour commander le déplacement latéral de l'ensemble de lame supérieur, est remplacée par une bielle latérale réglable (9). La bielle latérale (9) réglable en longueur est variable pendant l'action de coupe, permettant une action de roulement améliorée avec un patinage minime. La bielle latérale réglable (9) peut être mise en oeuvre sous la forme d'un cylindre hydraulique.
