Method and device for bending a portion of an element in a bending machine (12) comprising a bending assembly (14), a supporting plane (18) and an electronic processing unit (32), wherein the bending process is filmed and displayed on a screen (36). The portion (24) is bent with a first movement of the bending assembly (14) to make a first bend of a nominal value. By means of reference indicator elements an angle of deviation is determined and the portion is again bent with a new movement of the bending assembly (14), taking into account the angle of deviation. All movements of the bending assembly (14) are acquired by a position transducer (15) and recorded by the electronic processing unit (32) in order to have a global parameter for obtaining an angle which corresponds to the nominal value, and in order to use the global parameter in subsequent analogous or similar bends.
Method for bending a portion (24) of an element (11) in a bending machine (12), comprising at least a bending assembly (14), a supporting plane (18) on which said element (11) is retained by an arm (16), and an electronic processing unit (32), wherein the bending process is filmed by image acquisition means (26) and displayed on display means (36), the method comprising a step of setting a nominal value (“γ”) of the angle of bend to be obtained, characterized in that it provides that:
Method as in any claim hereinbefore, wherein said bending assembly (14) is driven, at least partially, by means of an impulse command, wherein an angle of partial bending, as acquired by said position transducer (15), corresponds to each impulse, characterized in that said electronic processing unit (32), during bending, algebraically adds together the total number of impulses, positive and negative, that is, with a deviation in one direction or the other of the bending assembly (14), necessary to actually obtain the value of said nominal angle (“γ”).
Method as in claim-5, characterized in that the drive of the bending assembly (14) is carried out continuously until said bent portion (24) is at a certain distance from the position of said first reference indicator (Z) and then is brought progressively closer by means of impulses in order to prevent the nominal angle (γ) to be obtained from being exceeded.
Method as in any claim hereinbefore, characterized in that the alignment between the bent portion (24) and the reference indicators (“Z, Z′”) is visually verified on each occasion on said display means (36).
Method as in any claim from 1 to 6 inclusive, characterized in that the alignment between the bent portion (24) and the reference indicators (“Z, Z′”) is signaled automatically.
Method as in any claim hereinbefore, characterized in that the calculation of said angle of deviation (“α”) provides that on said display means (36) a virtual straight line (Y) is generated on each occasion aligned with said bent portion (24), and that the angle is calculated between said virtual straight line (Y) and the first reference indicator (“Z”).
Method as in any claim from 1 to 8 inclusive, characterized in that the calculation of said angle of deviation (“α”) provides that on said display means (36) a system of coordinates is displayed, divided into a plurality of angular sectors to each of which is attributed a range of values of angles with respect to a reference axis (“X”), and that, displaying the position of said bent portion (24), the angle of deviation (“α”) is obtained as a function of the angular sector in which the portion (24) is located.
Method as in any claim from 1 to 8 inclusive, characterized in that the calculation of said angle of deviation (“α”) provides that the reference indicator (“Z”) is displaced until it aligns with the position of the bent portion (24) and the angle of deviation made is calculated.
Device for bending a portion (24) of an element (11) comprising a bending machine (12) including at least a bending assembly (14), a supporting plane (18) on which said element (11) is retained, an electronic processing unit (32), image acquisition means (26) able to film the bending process, and display means (36) able to display said images, characterized in that it comprises:
Device as in any claim from 12 to 14 inclusive, characterized in that said bending assembly (14) is associated with an actuation assembly (17) having the commands (39, 41, 43) for the drive functions of said bending assembly (14), at least part of said commands being associated with said position transducer (15) in order to find the parameters relating to said drive of the bending assembly (14).
