Power transmission tower plate bending angle real-time sensing device and angle sensing method

Abstract

The invention discloses a power transmission tower plate bending angle real-time sensing device and an angle sensing method, and belongs to the technical field of plate forming machining. The sensing device comprises a hydraulic bending machine which is arranged on the workbench and is used for bending and forming a steel plate, a plurality of laser distance measuring sensors which are arranged on two sides of the upper part of a rack of the hydraulic bending machine, and a controller which communicates with the laser distance measuring sensors; the laser distance measuring sensor measures the displacement of the upper die in the bending machining process of the steel plate, and the controller receives and processes the displacement of the upper die and displays the angle change of the steel plate in the bending machining process in real time. The induction method comprises the steps that a bending angle and descending displacement corresponding numerical table and a rebound database are established, and the displacement amount is converted into a forming angle to be displayed in real time by calling data. The device is simple in structure and high in precision, and the forming angle can be conveniently monitored in real time in the steel bending machining process.

Description

Technical field [0001] The present invention relates to the field of sheet molding processing techniques, in particular, a real-time sensing device and an angle sensing method of a bending angle of a transmission tube plate material. Background technique [0002] The transfer iron tower plate bending machine is made of a hydraulic bending machine to make the steel plate, bending machine on the table, the upper mold (bending knife) of the bending machine (bending knife) and the hydraulic cylinder hinged, by hydraulic cylinder push up the mold Shift, with fixed lower mold, extruded plate, realize the process of bending, due to the type of steel tower plate bending member, the same steel tower plate bending member, in the transmission tower plate bending In the process, the principle of free bending is often used, and a set of molds can achieve a variety of angles of angles. [0003] At present, the process of machining process is measured and controlled by the cardboard. It cannot ...
