    MACHINE FOR BENDING A YARN-LIKE MATERIAL SUCH AS A PIPE,
    EQUIPPED WITH AN INTEGRATED CUTTING DEVICE
    Object of the invention
    The object of the present invention is a machine for bending a wire-shaped material such as a pipe, equipped with an integrated laser or plasma cutting device, suitable for reducing machining times and making operations more precise wire-cutting material.
    State of the art
    For production reasons, it is possible to subject a wire-like material, such as a pipe, below designated by the term "pipe", to cutting in order to create bores of different shapes and dimensions, a operation which is indicated below in summary by "drilling", before bending it or after bending it.
    The cutting operations carried out to manufacture the bores mentioned in a pipe, are carried out by machines which are different and separate from the bending machines.
    If a pipe is to be drilled before bending, the pipe is drilled using an appropriate machine and then loaded onto a bending machine for bending procedures according to the different machining programs. Said type of machining results in a great loss of time, as necessary for transferring the pipe to be machined from one machine to another, as well as a loss of time to achieve correct positioning of the perforated pipe to be bent on the machine bending.
    If a pipe is to be drilled after being bent, the bent pipe must be transferred from the bending machine to the cutting machine. In this case, the transfer of the bent pipe from the bending machine to the cutting one also causes, in addition to the transfer times, a difficulty in handling and correctly positioning the bent pipe on the cutting machine to continue the specified machining.
    In the two types of production described in the previous paragraphs, the pipes are stored in a stack before being loaded in order to subject them to the next machining step.
    If a pipe has to be drilled before bending, several pipes are drilled and a certain amount of perforated pipes, as determined by the machining program, is stored by stacking and only later, these pipes stored by stacking are loaded on the bending machine for bending procedures according to the different machining programs.
    If the pipes are drilled after being bent, several bent pipes, in an amount determined by the machining program, are stored in a stack and only later are gradually loaded on the cutting machines. In this case, in addition to the problems relating to the transfer of the bent pipes from the bending machine to that of cutting and in addition to the difficulty of handling the bent pipe, there are also problems for storing the bent pipes by stack, which cannot be simply stacked, but must also be positioned so that their surfaces and ends remain intact during stacking storage.
    As mentioned in the previous paragraphs, being forced to use two different machines for bending and drilling pipes requires a repositioning activity for the different pipes, which is of great importance. Let us think, for example, of the difficulties resulting from an exact identification of welding, taking into account that the bending must be correctly oriented compared to the welding of the pipe - The fact of being obliged to carry out a positioning for the cutting before and then to transfer the pipe to the bending machine, there is also a need to reposition twice for welding. In the current state of the art, such positioning takes place manually or using a robot. A disadvantage of these known solutions lies in the fact that an operator must be designated for a repetitive and alienating activity or else, if using a robot, one must face complex and time-consuming robot programming activities.
    On the contrary, in the case of bent pipes which must be drilled after, the known art must face the problem of calculating the cutting positions with respect to the bending positions, in that it is necessary to have references in order to continue such an operation, so that it is necessary to solve the problem of positioning the cutting position relative to the bending position.
    Description of the invention
    The disadvantages of known machines are resolved by a machine according to the present invention.
    The fact that you don't have to transfer a pipe for bending and drilling, or drilling and bending from one machine to another definitely brings an advantage. However, as far as drilling operations are concerned, it is necessary that a pipe can be manipulated horizontally and that it can turn on itself to continue drilling operations in all the necessary positions of the pipe surface . For a correct drilling, the cutting device must be able to approach and move away from the surface of the pipe to be drilled according to specific machining programs, as the distance of the cutting element from the surface of the pipe is conditioned by the resistance to the shear stress characteristics of the pipe surface, by the cutting force of the device and by the need for more or less important drilling precision. Also, in order to be able to make bores of different shapes, the cutting device must be able to move horizontally, circularly or in a rocking motion.
    The machine according to the present invention is suitable for achieving the aims mentioned above, by making the transfer of the pipes from the bending machine to the cutting one and vice versa unnecessary, by being equipped with a first cutting device integrated in the bending machine.
    The machine according to the present invention comprises a fixed support frame, on which slides a handling and pipe rotation carriage, hereinafter designated in summary by handling carriage. Such a handling carriage slides on a plane of the fixed support frame. Such a handling carriage positions the pipe to be machined on the bending head, but it is also suitable for bringing the bent pipe back onto the sliding plane of said carriage. Such a handling cart is also suitable for rotating the pipe on itself before, during and after being bent.
    Such characteristics of the handling carriage allow the drilling of the pipe to be continued, both before and after bending it, using a first cutting device. Such a device can alternatively be a laser or plasma cutting device. Such a device slides along the guide means positioned above the fixed support frame and in particular above the sliding plane of the pipe handling carriage.
    Said guide means of the first cutting device consist of at least one rail and said rail is preferably parallel to the plane on which the mentioned handling carriage slides.
    The guide means are also equipped with a second handling device which is associated with the first cutting device. Said second handling device is suitable for allowing the first cutting device to approach or move away vertically, as well as to move said cutting device horizontally.
    In a preferred embodiment, the second manipulation device is also suitable for moving the first cutting device in a circular or tilting manner. Said second manipulation device is connected to a programmable control unit in order to manipulate the first cutting device according to a machining program set by the machine manufacturer or by the user.
    Cutting a pipe inevitably produces chips. Such chips must be removed from the perforated pipe and for this activity, the machine according to the present invention comprises a third chip suction device. This third suction device is connected to the guide means or, as a variant, to the second handling device which displaces the first cutting device. In the embodiment which comprises this third suction device connected to the guide means, said third suction device is equipped with a fourth handling device for moving the third suction device along the guide means where the first sliding cutter.
    If the dimensions of the cutters are too large for the third chip extraction device, a te! device is equipped with suction device blocking means. Such blocking means can be appropriately programmed sensors.
    The machine according to the present invention is also equipped with sensors placed alternately or jointly on the sliding plane of the pipe handling carriage and / or on the first guide means. Such sensors connected to a programmable control unit are connected to the handling trolley to position it according to an appropriate machining program in order to continue, precisely, the drilling of the pipe according to the services of said machining program.
    An advantage of the machine according to the present invention, which combines the two machining processes mentioned above into one machine, resides in the fact that its operation can be controlled by the operator using suitable visual inspection means, by example of dedicated cameras, operators being protected from harmful light from the cutting device. Think of the cabins in which operators can take shelter while controlling bending and cutting operations or cutting and bending the pipe, via appropriate monitors connected to appropriate and specific cameras using a machine according to this invention.
