Definitions

  • the invention refers to a machine which process circular section wire, including straightening, two directional bending and cutting.
  • the machine consists of: -a system forcing torsion , pulling and steaightening.
  • -a bending system capable of bending the wire in two di­rections with adjustable curvutuve radius and mounted cutter, which follows wire while bending and may cut t­he wire in any position.
  • the upper straightening rollers are not driven directly and they force a slight wire torsion, as it is explained analytically in the following.
  • the advantage of the bending system is that only two pi­ns are used for two direction bending. In each bending one acts as the pin around which wire is bent and the o­ther one as the bending pin. For counter bents functions of both pins alternate.
  • the on the benter fixed cutter enables cutting of wire while bender is rotated or directly after bent, without leaving a straight portion if desirable.
  • the above mentioned function is explained analytically using figs 1,2,3.
  • roller plane is rotated by an angle(w), around an axis vertical to OX and passing through the roller cent­erpoint, torsion of the straightened and pulled rod is achieved as it is proved theoretically and practically.
  • the rotation of the roller plane thus deviating from the up to now used through OXpassing plane and the important result achieved through this rotation on the controlled rod torsion build the substance of the here described invention.
  • This controlled torsion enables forming of perfect 2 - D shapes and complicated 3-D shapes on automatic rod bending machines.
  • roller (1) is rotated by an angle (w), coun­terclockwise in Fig (1), taking position (1′) and conta­cting rods on points (E1) and (E2).
  • Points (E1) and (E2) move both on the with a relocity ( u ) pulled rod (2) and on the with the vocational speed ( V ) rotating roller.
  • the number of the non adjustable rollers (1) as well as of the adjustable ones(2) may be anyone.
  • the numbers of non adjustable and adjustable rollers may be equal to e­ach other or differ by one.
  • the distances between the n­on adjustable rollers and the distances between the adj­ustable ones may be equal to each other or differ from each other.
  • Non adjustable and adjustable rollers may have or may not have grooves.
  • metal wire(14) is put between rollers(1)and (2). Trapping of metal wire (14) between non adjustable(1)and adjustable rollers(2) is acheived by moving the laters to the formers. Moveme- is acheived by pistons(12), which stretch out pressing through housing (11) shaft(10), bearing the disks with adjustable pins(9).
  • the number of disks(9) is equal to the number of the ad­justable rollers(2).Each disk(9) bears some adjustable pins(15), placed if possible on the corners of a regular polygon. The length of each pin (15) may be adjusted thr­ough a bolt.
  • the pins (15) are grouped. Each group has a pin number, equal to the disks(9) and the pins of every group, belonging one to each disk, lay on the same, thr­ough shaft (10) passing level.
  • the disks (9) are actual­ly normal to the shaft (10), but for visualization purp­oses are drawn , turned by 90° on the drawing level.
  • the disk shaft positioner (13) defines the pin group, which will press the adjustable roller supports(4) through ro­tation of shaft(10).
  • non adjustable rollers (1) are driven by motor (3) in rotation direction (17) , wire moves towards pulling di­rection(16).
  • Any type of motor may be used , but the hyd­raulic one gives best performance.
  • Roller driving may be also supplied by more than one motors , each motor driv­ ing one group of rollers(1). In Fig.2 , only one motor (3) is presented schematically through a chain of all t­he non adjustable rollers(1). If the rotation direction (17) of motor (3) is reversed wire pulling direction(16) changes.
  • a group of pins (15) is preset, having preset the lengths of the p­ins to give best pulling and straightening, as it is de­scribed later on.
  • setting of the feeder is ac­heived very quickly and preciselyfor the wire diameter to be feeded.
  • the end of the approach between rollers is determined by the pistons.(12).
  • adjustable rollers (2) in respect to the non adjustable rollers(1) guarantees a plastic d­eformation of the wire on the contact points between wi­re and rollers. This deformation differs from roller to roller depending on the setting of the respective pin(15)
  • the elastic comeback of the wire after its plastic defo­rmation is exactly sufficient to give ti the wir a stra­ight form on the level, which is normal to the paper le­vel of the drawing.
  • a second mechanism is required, similar to the one desc­ribed above. Its rollers should lay in a level normal to the drawing level, and it should be located directly af­ter the first one in a distance not causin plastic defo­rmation to the processed wire.
  • the adjustable rollers supports(4) may be rotated round the axis of rotation(18), using levers(6) and the common transmission bar(7), driven by the double direction pis­ton (8) to left or to right.
  • the roller support(4) rota­tes in its housing (5) around axis (18) by a small angle to the right or to the left in respect to the drawing l­evel.Due to friction , rotation of rollers(2) around ax­is (18) results to torsional movement of the pulled rod. This achievement is documented in my patent Nr87.0596/t.8 76/s.-191 of April 14th 1987, 00.30am.
  • Housing (10) remain always , parallel to itself, on level O ⁇ X.
  • the rotating body (1) of the bender may rotate freely , driven by a motor, fixed on body(1), through the chain gear(23) and the chain(24).
  • chain motion may have two directions: (31) and (32).
  • the rotating bo­dy(1) ends up at the interchangeable upper part(2) and d­own at the interchangeable lower part(3).
  • Parts (2) and (3) are fastened to body(1) by means of be­lts
  • the interchangeable upper parts(2) bears: a square openi­ng through which passes the moving cutter (9), the upper left(6) and upper right (7) pins of the cutter (8).
  • Pins (6) and (7) locate the fixed cutter (8) at a certain distance from the upper level of (2) and on the other ha­nd, they provide bending of the rod(21) passing between them.
  • the interchangeable lower part (3) bears only the lower left pin (5) and the lower right pin.
  • the draw-back spring (22) keeps housing (10) in such a p­osition that at least of pins (4) or (5) is placed inside the grooves (25) or (26) of plate (13) respectively.
  • the distance between the centerpoints of the semicircular grooves(25) and (26), the distance between the centerpoi­nts of the upper pins (6) and (7) are equal to each other Pins (4) and (5), as well as pins (6) and (7) may bear o­uter rings, to prevent their wear.
  • the outer diameter of pins(4) and (5) is equal to the diameter of grooves (25) and (26) respectively.
  • the outer diameter of pins (6) and (7) is equal to the inner diameter of the circles we want to form on the processed rod.
  • Metal rod (21) goes through pins (6) and (7) after passi­ng through the fixed wire guide(11).
  • Moving cutter is driven by a hydraulic piston, located in the rotating bo­dy. (1). These are one direction pistons . They are push­ed by high pressure oil and they are drawn back by a str­ong spring. Position of moving cutter(9) is of great imp­ortance for a) decreasing the moving cutter stroke in sm­all diameter rods and b) for givving next command to the bending head, directly after cutting.
  • the position marker (17) supplies outside information ab­out the position of transmission piston (14).Both result­ing spaces of the flexible pipe, (27) and (28), are fill­ed with oil after removing air.
