Definitions
- the invention relates to a measuring device for angles on machined edges or apices of a workpiece, in particular for bending angles of sheet-metal workpieces in a press brake, which comprises a bending tool consisting of a bending die with a rounded or chamfered working edge and a bending die with a contact surface and a bending groove , wherein an upper cross member holding the bending die or the bending die and / or a lower cross member supporting the bending die or the bending die perform a folding movement controlled by a measuring system.
- the invention further relates to methods for measuring bending angles in a press brake and for creating a calibration matrix for a measuring device.
- A1 4036289 relates to a method and a device for detecting bending angles of a metal sheet during bending and a method for bending a metal sheet.
- the measurements are carried out with the aid of a device which includes differential transmitters and pneumatic measuring devices.
- a device which includes differential transmitters and pneumatic measuring devices.
- differential transmitters for example, two E-shaped differential transmitters are arranged, each of which comprises a magnetic core with a central primary winding and two secondary windings.
- four pneumatic measuring devices emit a gas flow, for example an air jet, which is directed perpendicular to the assigned wall surface. In both cases, the two measurements are carried out using means known per se. The measurements are not made with probes and within the leading edge of the bending groove.
- peripheral probes continuously follow the associated leg of the sheet during the folding process, the longitudinal displacement of the probes in the y direction being converted into signals by the transducer
- a stop can be used to insert the sheets, which is removed by the bending punch after the clamping point has been reached.
- the relative bending movement of the punch and / or bending matrix can be controlled and limited in the usual way.
- FIG. 1 is a perspective view of a press brake
- FIG. 2 is a bending tool with an inserted, still flat sheet
- FIG. 8 shows a bending die with a calibration body placed in the bending groove
- FIG. 9 shows a folded sheet placed in the bending groove for quality control
- a bending die 24 On a stationary lower cross member 22 with the z-axis drawn in its longitudinal direction, a bending die 24 is fastened, which has a bearing surface 50 in the direction of the bending die 18.
- An essentially V-shaped bending groove 26 runs parallel to the working edge 20, which penetrates into the bending groove 26 when the punch 18 is lowered.
- the bending groove can also be essentially U-shaped, rectangular or rhombic.
- a device 66 known per se for detecting the relative movements of the measuring probes 38 relative to the measuring device 60 in the y direction, a mechanical-electrical measuring transducer 68 for generating signals from the longitudinal displacement of the measuring probes 38 and a processor 70 with a stored calibration matrix for adjustable angle ⁇ arranged and indicated by dashed lines.
