Flexible loading platform for sheet metal laser bending

Abstract

The invention provides a flexible loading platform suitable for sheet metal laser bending forming, which relates to the technical field of laser processing and forming, including a top cover, a slide table, a bottom plate, an upper pressing head, a lower pressing head, a force sensor, a lift, a motor assembly and A plurality of columns, the top cover, sliding table, and bottom plate are arranged in parallel in sequence and connected by multiple parallel columns. The upper pressing head and the lower pressing head are installed on the top cover and sliding table respectively; the elevator and motor components are all installed on the bottom plate On the top, the upper and lower parts of the force sensor are respectively installed on the slide table and the elevator; when the sheet material is subjected to laser bending and forming operations, the motor assembly drives the elevator to rotate so as to drive the lower pressing head to move closer to the upper pressing head. The invention performs laser bending and forming flexible loading operation on the sheet material used for aerospace products, improves the processing quality of the sheet material, satisfies the processing requirements of various sheet materials used for aerospace products, and has broad application prospects and popularization value.

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.

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
