Definitions

  • the invention refers to a machine for cutting and bending of iron rods by use of mobile heads and displaceable per section holding guides of straight rod , which cuts and bends straight iron rods, thus forming concrete reinforcement in various shapes and sizes. It accepts a plurality of regulations and motions so as the programmed-in-computer shape of armature to be automatically formed.
  • Machines relative to the present invention exist in the market. They carry head for propulsion and cutting of straight iron rod as well as movable formation heads.
  • the movable heads are one or two and, due to the lack of a movable holding guide of straight iron rod, a greater number of steps is needed for the completion of an armature shape, thus, the time needed for a bending cycle increases.
  • due to the unique intake of the iron rod as well as the one or two bending heads that each machine carries there is no capability for simultaneous formation of various shapes -given that the size of the shape affords this simultaneous formation- which would also mean double productive ability.
  • the machine for cutting and bending of iron rods by use of mobile heads and displaceable per section holding guides of straight rods is characterized by the fact that it constitutes a combination of cutting machinery and bending machinery of iron concrete.
  • Each section used in the productive procedure is driven via commands, which are given by the control-panel, having as a result the accurate adaptation to the specifications of the shape to-be-formed. It bears a head for cutting the straight iron rod and advancing it towards the bending heads.
  • the heads for cutting and advance may also be two, placed on the right and left side of the framework of the machine.
  • the machine for cutting bending of iron rods by use of mobile heads and displaceable per section holding guides of straight rod consists of the metallic framework (1) which is also the base for the assembly of the mechanisms and components of machine.
  • a head (2) for the advance and cutting of the iron concrete rod is placed, which is a patent of the applicant and bears Hellenic Industrial Property Organization Patent No: 1004632/14-2-2003 , titled: System for propulsion and cutting of iron concrete rod.
  • the System is provided with a rotating head of rolls (3) which consists of two pairs of plastic rolls, highly adhesive to the iron concrete rods of all cross-sections that they can advance; following to the head, a pair of rolls (4) is placed which function as counters of length of straight iron and as guides of iron rod towards the cutting head (5) and towards the pair of advance rolls (6) which advance the iron rod towards the bending heads.
  • the regulation of the rolls is proportional to the size of the iron's cross-section for the best adhesion of the rolls at the iron concrete rod.
  • the rolls at the System for propulsion and cutting of iron concrete rod have the ability, apart from the forward movement (advance), to carry out also backward movement.
  • a hydraulic unit (8) is installed, which feeds the corresponding hydraulic motors and mechanisms of the head (2).
  • a second head for advance and cutting (2) can be installed, according to sheet 2- figure 2 .
  • the bending heads can be from three and more, they are placed lengthwise the framework (1) -which is destined for the bending procedure- and their number depends on whether they will bear one or two heads for advance and cutting (2).
  • Each bending head (sheet 3- figure 3 ) consists of a plate (7) at the center of which is installed a bending head (9) which is a patent of the applicant and bears Hellenic Industrial Property Organization Patent No: 1004760/26-11-2003 , and European Patent No: 1535675/21-10-2004 titled: Four-direction mechanism for iron concrete rod bending with cutting ability of the front and rear end.
  • a bending head On the bending head, only the part of the mechanism which concerns the bending (9) is installed, since the cutting is carried out by a component of the head for advance and cutting (2).
  • the bending head can rotate on the right or the left, depending on the bending demands, with the aid of motor and drive unit which is placed on the bending head.
  • the plate (7) moves -after programmed command- right-left by use of motor (10) and toothed ruler-gear (11) with the aid of four sliding rolls (12) and guides (13).
  • mobile holding guides of the straight iron rod (sheet 4 - figure 4 ) are placed -per sections- which consist of the articulated brace (14), which moves forward-backwards with the aid of piston (15), and the articulation (17). This movement is necessary so that space is disengaged during the displacement of the bending plate (sheet 5 - figure 5 ).
  • the articulated brace (14) bears jaw for the holding of the straight iron rod.
  • This jaw (sheet 6 - figure 6 ), on its upper part, has the ability to open and close with the aid of piston (19) and guide (20), so that, during the backward movement of the articulated brace (14), the straight part of the rod to be disengaged; while, at its lower part (21), the jaw opens and closes with the aid of piston (22) and articulation (23), thus, it fully disengages the straight iron rod pieces that it holds (sheet 7 figure 7 ).
  • corridors are placed for the collection of the formed shapes, which are placed, depending on their size and shape, in one of the three corridors.
  • the first two corridors bear sliding rolls (24) for the easy removal of the formed shapes which usually are straight, open-type parts bended at the ends.
  • the third corridor (25) is open, it accepts more complicated schemes -as those of closed type (squares, polygons)- of various sizes, which are deposited on the ground or onto a special collection carriage, that is at the lower part of the corridor (25), and consists an optional structure.
  • the machine for cutting bending of iron rods by use of mobile heads and displaceable per section holding guides of straight rod, at its base, bears four wheels (26) which run on a constant trail (27) by aid of motor (28).
  • the feeding of the machine is achieved directly by straight iron rods, by iron-coil or by using both occasions simultaneously, when regards a machine that bears two heads for advance and cutting (2).
  • the iron-coil is placed on a coil-holder (30) and then it passes through an independent straightening rolls system (31) as the one of the applicant bearing Hellenic Industrial Property Organization Patent Application No: 20050100201/20-4-2005 , and European Patent Application No: 06386006.8/18-4-2006 , titled "Feeder of concrete armature assembling machine” which includes iron rod straightening rolls system or other system having the specific ability.
  • the feeding is directly by straight iron rods (32) (sheet 10- figure 10 )
  • the rods are placed onto a bench (33), they are advanced to the intake of the head for advance and cutting of straight iron rod (2) and the bending procedure follows.
  • the commands for the function of the machine are given by an in-built control-panel (34).
  • the machine for cutting bending of iron rods by use of mobile heads and displaceable per section holding guides of straight rod is placed on rails and, preferably, in an indoor site. First, it is selected whether the machine will be fed by straight iron rod or by iron-coil and, then, the shape and the size to be bended are programmed at the control panel.
  • the iron-coil In case of choosing the feeding by use of iron-coil (29), the iron-coil is placed on the coil-holder (30) and, via the straightening rolls (31), the finally straight iron rod is introduced in the head for advance and cutting of the rod (2).
  • the straight rods are placed upon the bench (33). The end point of the rod is introduced in the head for advance and cutting of the iron rod (2) and the rod is advanced via the rolls head (3), the rolls for counting the rod's length (4) and the rolls (6) towards the bending head (9). According to sheet 15, the straight iron rod is advanced as much as the length of the shape's span. Through the counting rolls (4) the length is measured and the rod is cut by use of the cutting head (5).
  • the intermediate bending head (9) receives the rod by making a slight rotation of the bending jaws and it carries it as much as needed, so as the heads to be able to realize the bending programmed, while the two heads at the ends move simultaneously towards the corresponding programmed points ( figure 31 ).
  • the right and left heads carry out the first bending ( figure 32 ) and the jaws return to their initial position, while the intermediate head and the movable guides for holding the straight rod (14) retain the straight part.
  • the two bending heads (9) move inwards ( figure 33 ) for as much as the length of each side that is to be bended, while the mobile holding guides (14) hold the iron rod and the intermediate head retains the rod's position. During this shifting phase, some of the holding guides (14) are displaced backwards, so as to disengage space for the movable bending heads (9), sheet 5, figure 5 .
  • the bending ( figure 34 ) follows and the procedure is repeated until the shape is completed ( fig.35, fig.36, fig.37 ).
  • the machine can accomplish a variety of movements and bending phases, depending on the operator's consideration.
  • the above-mentioned application example can be also applied to a machine for cutting and bending of iron rods by use of mobile heads and displaceable per section holding guides of straight rods with two heads for advance and cutting (2) and more than three bending heads (9) installed, for simultaneous formation of shapes and, thus, achievement of double production capacity.
  • mobile heads and displaceable per section holding guides of straight rods with two heads for advance and cutting (2) and more than three bending heads (9) installed for simultaneous formation of shapes and, thus, achievement of double production capacity.
