Flexible loading platform suitable for plate laser bending forming

Abstract

The invention provides a flexible loading platform suitable for plate laser bending forming, and relates to the technical field of laser processing forming. The flexible loading platform comprises a top cover, a sliding table, a bottom plate, upper pressure heads, lower pressure heads, a force sensor, a lifter, a motor assembly and multiple stand columns. The top cover, the sliding table and the bottom plate are sequentially arranged in parallel and are connected through the multiple parallel stand columns. The upper pressure heads and the lower pressure heads are mounted on the top cover andthe sliding table correspondingly. The lifter and the motor assembly are mounted on the bottom plate, and the upper portion and the lower portion of the force sensor are mounted on the sliding table and the lifter correspondingly. When the operation of laser bending forming is carried out on plates, the motor assembly drives the lifter to rotate, and therefore the lower pressure heads are driven to move close to the upper pressure heads. The flexible loading platform carries out laser bending forming and flexible loading operation on plates used for aerospace products, the processing quality of the plates is improved, the processing requirements of the multiple plates used for aerospace products are met, and wide application prospects and popularization value are achieved.

Description

technical field [0001] The invention relates to the technical field of laser processing and forming, in particular to a flexible loading platform suitable for laser bending and forming of sheet metal. Background technique [0002] At present, the curved sheet metal used for aerospace products requires high precision. The laser bending forming technology of sheet metal under preload has the characteristics of high forming accuracy and good process repeatability. At present, the platform used for sheet metal loading has no laser scanning area, cannot realize quantitative load loading, lacks the flexibility to adjust the position of the bending point, and cannot be used for laser bending forming, which affects the processing accuracy of curved sheet materials for aerospace products. [0003] Patent document CN108655213B discloses a bending forming method for sheet metal parts. The bending forming method adopts the following multi-roller floating bending machine.

At present, the platform used for sheet metal loading has no laser scanning area, cannot realize quantitative load loading, lacks the flexibility to adjust the position of the bending point, and cannot be used for laser bending forming, which affects the processing accuracy of curved sheet materials for aerospace products.

[0003] Patent document CN108655213B discloses a bending forming method for sheet metal parts. The bending forming method adopts the following multi-roller floating bending machine. The multi-roller floating bending machine includes a machine body, a pressing module, a main pressure head, and a pressure dividing head , adjustment unit, movable mold and fixed mold, the body is provided with a controller; the controller is located on one side of the body; The head is fixedly connected to the pressing module; the structure of the dividing head is the same as that of the main pressing head, and the dividing head and the main pressing head are used to bend the sheet metal; the adjustment unit is located between the dividing head and the pressing module, and the adjusting unit is used to adjust The pressure divider rises or moves left and right; the movable mold is located on the lower side of the machine body, and the movable mold is slidingly connected with the machine body. The movable mold is used for bending sheet metal parts, but this design still cannot meet the loading requirements, and the design is unreasonable
