Roller adjustment device, adjustment method and application thereof, and bending machine

Abstract

The invention discloses a roller adjusting device, an adjusting method and application of the device and a bending machine comprising the device, and belongs to the technical field of bending machines. The roller adjusting device is mounted on a cylinder of the bending machine; the roller adjusting device comprises a mounting base, a roller component and an adjusting component; the roller component is connected with the mounting base through the adjusting component; the adjusting component can be used for adjusting the roller component to move forwards and backwards relative to the mounting base; the roller component is in contact with a sliding block; the adjusting component comprises an adjusting thread sleeve, an adjusting screw nut and an adjusting screw; the adjusting thread sleeve is of a tubular structure and is in threaded connection with the mounting base; the adjusting screw nut sleeves the adjusting thread sleeve; the adjusting screw penetrates through the adjusting thread sleeve and is connected with the roller component. According to the adjusting method of the roller adjusting device, the roller component is adjusted by the adjusting component to move forwards and backwards so as to press the sliding block. By adopting the roller adjusting device, vibration of the sliding block can be alleviated in bending operation of a large-tonnage bending machine (the bending force is greater than 300t), the bending precision can be improved, the product pass percentage can be increased, and the service life of a cylinder can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of bending machines, and relates to a roller adjustment device, an adjustment method and its application, and a bending machine, more specifically, to a roller of a slider of a bending machine with a large tonnage (bending force greater than 300t) Adjusting device and adjusting method thereof. Background technique [0002] The hydraulic sheet metal bending machine uses two parallel-moving working hydraulic cylinders to form a vertical downward pressure to drive the mold on the bending beam to bend the workpiece. Bending machines are used extensively in the field of sheet metal forming. The bending machine bends the plate into a designed angle by stamping the plate with the upper die installed on the slider relative to the lower die installed on the workbench. The slider is installed on the left and right vertical plates of the rack and moves up and down through the guide rails, and the back is connected to...

Problems solved by technology

[0007] Aiming at the problems of the existing large tonnage bending machine (bending force greater than 300t) during the bending operation process, the vibration of the slider causes the bending accuracy to decrease and the service life of the oil cylinder to be reduced. The present invention provides a roller adjusting device, an adjusting method and Its application and bending machine, the roller adjustment device is installed on the large-tonnage bending machine, and the slider of the bending machine is pressed and adjusted by adjusting the adjustment of the roller adjustment device to reduce the vibration of the slider during the bending operation, thereby solving the problem of above question
