Abstract
The invention relates to a curve simulation S-shaped wedge block compensation device. The curve simulation S-shaped wedge block compensation device comprises a compensation groove platform, a plurality of upper S-shaped wedge blocks, an integral lower S-shaped wedge block, a bottom plate, adjusting screws and a transmission mechanism, wherein the upper S-shaped wedge block and the integral lower S-shaped wedge block are placed in a groove in the bottom of the compensation groove platform in a matched mode, the bottom plate is fixedly connected with the compensation groove platform through bolts, and the adjusting screws penetrate through the compensation groove platform and are connected with nuts embedded in the upper S-shaped wedge blocks. The transmission mechanism comprises a first lead screw, a second lead screw, a connecting block, a motor and a speed reducer, the motor and the speed reducer are fixedly installed at one end of the compensation groove platform through a first connecting block, the right end of the first lead screw is connected with the speed reducer, an internal thread at the left end of the first lead screw is connected with an external thread at the right end of the second lead screw, and the left end of the second lead screw is connected with the lower S-shaped wedge block through the connecting block. By means of compensation for deformation of a machine tool, the curve simulation S-shaped wedge block compensation device can improve accuracy of the angle and the straightness of a bent workpiece, and guarantees product quality of the bent workpiece.
Description
technical field [0001] The invention relates to a curve-simulating S-shaped wedge compensation device, which belongs to the technical field of bending machine equipment. Background technique [0002] Sheet metal bending machine is a widely used sheet metal processing equipment. By using the simplest bending die, adjusting the pressing depth distance of the slider, performing bending at various angles, and bending various complex parts. The lower die of the bending machine is installed on the lower beam of the workbench, and the upper die is installed on the slider. During the working process, the slider of the bending machine is subjected to an upward uniform load, while the workbench is subjected to a downward uniform load. Under the action of the uniform load, the slider and the workbench will move along the direction Deflection occurs, resulting in deflection. The generation of deflection changes the distance and pressure between the upper mold and the lower mold in th...
