Definitions

  • the invention is a method and a device for the production of continuous spirals with any, closed, polygonal, constant winding forms made of wire, reinforcing steel or a metallic tube.
  • Spirals of this type are used in many areas. For example, it is known that spirals with closed polygonal, but mainly with right-angled coil shapes made from wire or rebar are used in the reinforcement of reinforced concrete structures and Find elements such as support columns and beams, large sewer pipes Dimensions and the like.
  • Spirals of this type are usually made manually or with the help of simple (automatic or non-automatic) bending devices used for Manufacture of rebar, clamps and other wire products be used.
  • This production method has the following disadvantages: Bending each corner of a spiral turn will advance the Wire stopped with the result that productivity remains low. Furthermore pushes the advanced wire pushes the already produced turns the spiral until due to friction and the weight of the Product plastic deformations of the turns already produced enter. Because of this, the dimensions are this way produced spirals, limited.
  • the aim of the invention is to solve the problems described above by it offers a simple and quick method that is automated manufacturing of quality spirals made of wire, reinforcing steel or a metallic pipe allowed.
  • the invention relates to a device that automatic Production of spirals from wire, reinforcing steel or a metallic pipe makes possible to offer and the simple in the construction, reliable in the Functionality that is high in productivity and easy to use.
  • the invention provides a method for making spirals arbitrary, closed, polygonal, constant winding forms Wire, reinforcing steel or a metallic pipe (1), which results from this is characterized as first of all the winding of the wire, Reinforcing steel or metallic pipe, under sufficient tension, on suitable arranged bending rods (7) which are suitably mounted on a rotating device are required.
  • the method requires bending every single corner of the Spiral turns simultaneously with the rotation, the ejecting of the already produced turns of at least one diameter of the wire, Reinforcing steel or the metallic pipe (1), so that the production level for the next one to the producing turn becomes free Bending tools of the bending device (6) happens so that the Production level for obstacle-free winding of wire, reinforcing steel or of the metallic tube (1) is released.
  • the invention provides this device, the this method is implemented.
  • the method in the sense of the invention calls for the design of everyone single corner of the winding form a bending device (6), that is, if the turns of the spiral have a triangular shape if they have one Rectangular shape have four bending devices, etc.
  • Drawing 1 shows a front view of the winding device of the wire and the bending devices for the production of spirals with constant rectangular winding shapes in the sense of the invention.
  • Drawing 2 shows a bending device in the sense of the invention.
  • Drawing 3 is a schematic front view of the device according to the invention.
  • Drawing 4 is a schematically illustrated top view of the device according to the invention.
  • Drawing 5 ⁇ shows schematically an example of the device for spirals with octagonal constant winding forms, in the sense of the invention.
  • Drawing 5 ⁇ shows schematically an example of the device for spirals with triangular constant winding forms, in the sense of the invention.
  • Drawing 5 ⁇ schematically shows an example of the device for spirals with right-angled constant winding shapes made of a metallic tube, in the sense of the invention.
  • the wire (1) comes from a reel (13) mounted on a reel and is pulled from the bars (7) with the help of a straightening unit (12) and directed.
  • the bars are part of four bending units (6) on one store rotating device.
  • the Wire (1) is wound around the rods (7) and is turned on simultaneously with the rotation each corner of the turn is bent by the corresponding bending unit (6).
  • the turns are produced with the help of an ejector (11) pushed outside the production level so that at that level Space for the production of the next turn is created.
  • the method described above in the sense of the invention can be implement the device described in detail below.
  • the single ones Functions are monitored by a computer-controlled control unit and controlled.
  • the wire (1) is located on a reel (13) Coil and is by the rods (7) around which it is wrapped by a Straightening unit (12) in which it is judged.
  • a Straightening unit (12) in which it is judged.
  • On the spinning Four bending units (6) are mounted on the device (drawing 1), two each each bar (4) and (5) on either side of the center. You can click on the Beams (4) and (5) can be moved and placed in a suitable position Be secured with the help of suitable security mechanisms.
  • the Beams (4) and (5) are in turn on the beam (3) with plain bearings (15, 16) stored accordingly and can be moved to it. In this way can each bending unit (6) on any coordinate point of the corresponding quarter of the production level of the spiral windings be positioned and thus a quick and easy adjustment of the Device according to the desired shape of the winding producing spiral.
  • the two bending pins (8, 9) are extended above the production area and only bend when the piston (10) presses them onto the wire, reinforcing steel or metal pipe (1) to be bent.
  • the bending pins (8, 9) are moved below the production level so that they cannot hit the drawn wire, reinforcing steel or the metallic tube (1) during the winding.
  • the displacement of the last spiral produced outside the production level takes place with the aid of the ejection device (11), which is suitably synchronized with the piston (10) of the bending device (6).
  • the piston (10) of the bending pins (8, 9 ) of the bending unit (6) from position ( ⁇ ) to position ( ⁇ ) and the piston of the ejection device (11) from position ( ⁇ ) to position ( ⁇ ).
  • the rods (7) incline slightly in a suitable manner so that the turns (14) which have already been produced can be moved away from the production level without difficulty.
  • the two bending pins (8, 9) are arranged in a suitable manner so that they move simultaneously and parallel to one another and to the bisector of the angle of the winding corner under under production, from the starting position A to position C (drawing 2), whereby the wire (1) is bent through an angle ⁇ ⁇ 90 ° .
  • the difference ⁇ - ⁇ 1 corresponds to the elastic recovery of the wire, reinforcing steel or the metallic pipe (1) because of its plastic-elastic behavior.
  • the desired angle ⁇ 90 ° is formed after elastic resetting of the wire, reinforcing steel or the metallic tube (1).
  • the pistons (10) of the bending units (6) and the pistons of the ejection devices (11) are driven hydraulically.
  • the hydraulic energy comes via the axis of rotation (2) through a distributor (17).
  • the valves that control the pistons are checked with the aid of suitable rings (21), which are located on the axis of rotation (2) and directly actuate the control switches (22).
  • the movement of the axis of rotation (2) is carried out with the aid of a hydraulic or electric motor (20) of constant or variable speed.
  • the operator of the machine hooks the wire end onto one a rod (7) located between positions ( ⁇ ) and ( ⁇ ) suitable disc (19), a. Then he turns on the machine
  • the rotating device rotates and the wire (1) is wound around the bars (7) while at the same time the corners of the turns one after the other from the corresponding bending units (6) can be shaped as described above to have.
  • the device in the sense of the invention is not a measuring device for the wire (1) because the lengths of the sides of the spiral turns of the position of the rods (7) are fixed.
  • the wire (1) is with Using suitable scissors cut manually or automatically after the desired spiral has been produced.
  • the finished spiral (14) is from removed from the bars (7) and the production procedure is only after the positions of the rods (7) are repeated, repeated.
  • the time saving that is achieved is related to that the bending of the wire (1) takes place simultaneously with the wrapping, without that the rotational movement of the axis of rotation (2) is interrupted or its Speed is reduced.
  • the method and the device allow in the sense of Invention the simple and fast production of continuous spirals with any closed polygonal constant winding forms Wire, reinforcing steel or a metallic pipe.
