Definitions

  • the present invention relates to a device for positioning sheet metal plates arranged on a support table of a plate shear according to the preamble of claim 1.
  • the object of the invention is to propose a device in which sheet metal sheets are cut at various locations on the cutting knife and the sheet metal sections are local can be separated into several stacks. Furthermore, the manipulation with the metal sheets is to be facilitated in that the side guide no longer forms any obstacle when manipulating with the metal sheets.
  • the stated object is achieved with the aid of a device which has the features listed in claim 1.
  • the device has features which are defined in claims 2 to 8.
  • the guide elements can be retracted, there is enough space, for example, to turn the sheet metal sections or to process sheet metal sections of different widths one after the other.
  • the device has a support table 1, which forms part of a sheet metal working machine, for example, a pair of guillotine shears, a lower knife, the cutting edge 2 of which extends horizontally across the entire table width, being arranged in a known manner on a knife holder at a table end.
  • a feed beam 3 At the other end of the support table 1 opposite the cutting edge 2 there is a feed beam 3, the design of which can also be assumed to be known.
  • the feed bar is equipped along its front edge with gripping members 4, each having an upper and a lower jaw, between which the sheet metal section to be positioned is gripped.
  • the lower jaws are arranged slightly below the surface of the support table 1, while the upper jaws are slightly above.
  • trench-like recesses are for receiving the lower jaws of the gripping members; sung 5 are provided, which lie in the path of movement of the gripping members 4 and extend from the front edge 6 of the support table 1 to the cutting member.
  • a bar 7 which runs perpendicular to the cutting plane and is supported on both ends in a trolley 8, which is arranged to move back and forth parallel to the cutting plane.
  • slot-shaped grooves 9 are provided in the support table 1, in which guide elements 10 are received, which are supported on the beam 7 and are designed to be raised and lowered.
  • the guide members 10 are thus spatially separated from one another and can be moved together by the movement of the bar 7 in the corresponding slot-like grooves 9 parallel to the cutting plane. In the lowered position, the guide elements are located below the table surface, while in the lift position the said guide elements protrude from the table surface, as will be described later.
  • FIG. 2 shows a guide element 10 which is designed as a double-sided embodiment, so that the guide element can grip and guide sheet metal sections separately from one another both on the right side and on the left side.
  • the guide member has a guide body 11, which is mounted on the bar 7, not shown, so that it can be raised and lowered.
  • a right-hand holding arm 13 and a further left-hand holding arm 14 are pivotally mounted about a central horizontal shaft 12.
  • Both holding arms are essentially L-shaped and are composed of an approximately horizontal and a vertical leg.
  • the vertical downward legs 13a and 14a are each provided with a horizontal guide pin 15 and 16, which are each guided in a slot 17 or 18 of a control head 19 or 20.
  • Each of the control heads can be displaced independently of one another by a separate hydraulic cylinder unit 21 or 22, as a result of which the holding arms 13 or 14 are pivoted.
  • a pressure roller 23 In the horizontal leg of the holding arm 13 is a pressure roller 23 and in the corresponding leg of the holding arm 14 a pressure roller 24 is mounted.
  • the surfaces of the rollers 23 and 24 are cambered and the axes of the rollers are slightly inclined so that the planes of rotation of the rollers each form an acute angle with the direction of advance.
  • a counter-holder Below the rollers 23 and 24 there is a counter-holder, which consists of a plastic plate 25 or 26, in which a ball 27 or 28 is supported.
  • the guide member 10 is designed such that it is provided with a side stop both on the right side and on the left side.
  • the side stops are formed by rollers which are mounted in the guide body 11 so as to be rotatable about a vertical axis 29 or 30 and are designated 31 or 32.
  • the aforementioned rollers 31 and 32 are arranged in the swivel ranges of the pressure rollers 23 and 24.
  • the pivoting is achieved by actuating the hydraulic cylinder units 21 or 22.
  • the holding arm 13 is in the upper pivot position into which the control head 19 has been retracted in the direction of the hydraulic cylinder unit 21.
  • the guide pin 15 slides in the slot 17 and causes the pivoting in the position shown. In this position, the pressure roller 23 is raised from the ball 27 forming the counter-holder, so that the roller 31, which forms a side stop, is freely accessible.
  • Roller 32 pushes, which forms the side stop.
  • the sheet metal section 33 is under the influence of the feed beam 3, which pushes the sheet metal section in front of it, the gripping members 4 of the feed beam remaining open. Since the pressure rollers 24 roll in a plane inclined to the central plane, a force is constantly exerted on the sheet metal section which presses the sheet metal section against the side stop roller 32.
  • a sheet metal section is held in the region of its rear edge by the gripping members 4 and is displaced in the direction of the knives by the movement of the feed beam 3 perpendicular to the cutting plane.
  • the bar 7 is previously set on the support table 1 in such a way that the one free longitudinal edge of the sheet metal section comes to rest in the region of the first roller 31 or 32 of the first guide member 10.
  • the corresponding setting of the bar 7 is carried out by moving parallel to the cutting plane.
  • the first guide member 10 in suitable moment sunk by the actuation of the lifting device, not shown, by a control under the surface of the support table 1.
  • the corresponding edge of the sheet metal section will slide one after the other along the rollers 31, the sheet metal section sliding on the surface of the ball 27 that protrudes somewhat from the plane of the support table 1.
  • the arrangement of the pressure rollers 23 inclined to the feed direction ensures that the edge of the sheet metal section is always against the Rollers 31, which form the side stop, is pressed. In this way, extremely precise sheet guidance is achieved.
  • two sheet metal sections can be cut at the same time, provided that they are narrower than half the table width.
  • the guide elements serve not only to maintain the vertical feed direction exactly, but also to grip sheet metal sections during a lateral displacement parallel to the knife plane. With such a movement, the drawn sheet metal section must be clamped.
  • the hydraulic cylinder unit is operated with increased pressure, so that the ball 27 serving as a counter-holder is pressed into its mounting and the sheet metal section is pressed onto the plastic plate 26 and held there.
  • a rotating device 34 is arranged in the center of the support table, it being possible for each sheet of metal with its center to be brought below the pivot point with the device described. This would not be possible with a fixed side stop rail, as this only allows one-way feed.
