    Machine for the serpentine bending of a thread-like material such as a pipe and its respective method
    Object of the invention [001] The object of the invention is a machine and its respective method for the serpentine bending of a thread-like material such as a pipe or similar semi-machined materials, such as a rod or a section bar to prevent the already bent parts of the pipe from being moved after every formation of each indi vidual turn of the serpentine.
    Present status of the art [002] The known machines for bending a thread-like material such as a pipe or similar semimachined materials such as a rod or a section bar, here below shortly referred to as pipe, make use of one bending head only.
    [003] According to the known art, the already bent part of the pipe is driven into rotation while it is bent, thus creating a number of limitations in the machining due to the mass and to the shape of the bent pipe.
    [004] A drawback in adopting one bending head only is in that it is not movable in the forwardmovement direction of the pipe while the head is positioned to carry out the subsequent bending of the pipe.
    Disclosure of the invention [005] The drawbacks of the known machines are solved by the machine according to the present invention.
    [006] The machine according to the present invention is a machine for the serpentine-bending of a thread-like material such as a pipe or a section bar, here below shortly referred to as pipe. Such machine is equipped with a first bending head assembly which is in an opposed position with respect to a second bending head assembly. Such bending heads are provided with handling means suitable for moving the first and second bending head assemblies on a frame. The second bending head assembly is connected to a support intended for receiving that portion of the pipe which has been serpentine-bent.
    [007] The first bending head assembly is provided with first handling means in order for said first bending head assembly to alternatively move forward or back along the frame to bend the pipe according to the bending method that will be illustrated below'.
    [008] According to the present invention, the second bending head assembly is also provided with handling means, specifically second handling means, which are preset to move the second bending head assembly in order for said bending head assembly to alternatively move forward or back along the frame to bend the pipe according to the bending method that will be illustrated below.
    [009] The first handling means are preset to move the first bending head assembly along a first vertical movement axis Ya. The second handling means are preset to move the second bending head assembly along a second horizontal movement axis Xb orthogonal to the first vertical movement axis Ya. Said second handling means are also preset to move the second bending head assembly along a third vertical movement axis Yc, parallel to the first vertical movement axis Ya, a fourth horizontal movement axis Xd parallel to the second horizontal movement axis Xb, so as to perform an arc-like movement of the second bending head assembly. The second handling means, after performing the above-mentioned arc-like movement, are suitable for making the second bending head assembly move forward along a fifth vertical axis Ye parallel to the first vertical axis Ya.
    [010] The present invention also provides for a method for the serpentine-bending of a pipe by using the machine according to the present invention. Such method comprises several steps.
    [011] In a first step, a pipe to be bent is loaded onto the first bending head assembly and onto the opposed second bending head assembly.
    [012] In a second step, the pipe to be bent is hooked to the first bending head assembly and to the opposed second bend heading assembly.
    [013] In a third step, the first bending head assembly operates so as to bend that portion of the pipe which is hooked to the first bending head assembly thanks to the joint operation of the bending tools aboard the first bending head assembly and of the first handling means which make the first bending head assembly move forward along the first vertical movement axis Ya according to the bending and forward-moving program entered either by the operator or by the machine manufacturer. Simultaneously, the second bending head assembly operates so as to bend that portion of the pipe which is hooked to the second bending head assembly thanks to the joint operation of the bending tools aboard the first bending head assembly and of the second handling means which make the second bending head assembly progressively move forward along the second horizontal movement axis Xb, along the third vertical movement axis Yc, along the fourth horizontal movement axis Xd, so as to realize an arc-like movement, up to bringing the second bending head assembly substantially in an opposed position with respect to the first bending head assembly. Such bending and movement of the second bending head assembly are implemented according to the bending and forward moving program of the second bending head assembly entered either by the operator or by the machine manufacturer. When this operating step is over, the first turn of the serpentine is formed and lays on the support connected to the second bending head.
    [014] The method goes on with a fourth step, wherein the first bending head assembly releases that portion of the pipe which has been bent in step 3 and positions itself outside the space occupied by the pipe to be bent, for instance by coming down with respect to the height of the mentioned pipe.
    [015] The method goes on with a fifth step, wherein the first handling means make the first bending head assembly move back along the first vertical axis Ya to bring said first bending head assembly to the same position it had at the beginning of the mentioned second step. Simultaneously, the second handling means make the second bending head assembly move forward along the fifth vertical axis Ye parallel to the vertical axis Ya.
    [016] In a sixth step, the second handling means make the second bending head assembly move forward along the second horizontal axis Xb thus bringing the second bending head assembly to the position it had at the beginning of the second step.
    [017] The steps following the sixth one go on progressively by bending the pipe and unhooking the bent pipe on the support intended for receiving the bent pipe which is connected to the second bending head assembly, by going through the steps from the second to the sixth one, up to reaching the end of the machining process established either by the operator or by the machine manufacturer.
    Description of the figures [018] Figures 1 through 7 graphically show the machine according to the present invention and illustrate its respective bending method.
