Embodiment Construction

[0041] Please check Figure 1 to Figure 9 , a rotating shaft type flipping and folding machine, which includes an upper device 100 and a lower device 200.

[0042] The upper device 100 includes an upper plate, an upper pressing plate 120 and an upper power mechanism. The upper power mechanism is mounted on the upper plate and connected to the upper platen 120 so as to drive the upper platen 120 to move up and down relative to the upper plate. In this embodiment, the left-right section of the upper platen 120 is a trapezoid with a large bottom and a small top. In this embodiment, the upper power mechanism adopts a hydraulic mechanism, which includes a hydraulic body and a hydraulic rod, the hydraulic body is fixed on the upper plate, and the end of the hydraulic rod is fixed to the upper platen 120 through the positioning seat 110 .

[0043] The lower device 200 includes a lower plate 210, a turning combination device 220 and a lower power mechanism.

[0044] The turning com...

Abstract

The invention discloses a rotating shaft type turnover flanging method and a flanging machine. The rotating shaft type turnover flanging method comprises the following steps of: 1, placing a plate material (300) on a lower plate (210); 2, moving an upper pressing plate (120) downwards to be pressed against the plate material (300); 3, lifting a turnover combination device (220), wherein in the lifting process of the turnover combination device (220), a turnover body (221) of the turnover combination device (220) is driven to rotate and one side (223) of a notch (222) of the turnover body (221) is pressed against to bend the plate material (300) to realize flanging; and 4, lifting the upper pressing plate (120) so that the upper pressing plate (120) is reset and descending the turnover combination device (220) so that the turnover combination device (220) is reset. The rotating shaft type turnover flanging method has the advantages of preventing the surface of the plate material (300) from being scratched and guaranteeing the flanging effect and the appearance quality.

Description

technical field [0001] The invention relates to a rotating shaft type flipping and folding method and a folding machine. Background technique [0002] Existing folding machine, it comprises an upper device and a lower device. The upper device includes an upper plate, an upper pressing plate and an upper power mechanism, and the upper power mechanism is mounted on the upper plate and connected with the upper pressing plate so as to drive the upper pressing plate to move up and down relative to the upper plate. The lower device includes a lower plate, a lower pressure plate and a lower power mechanism. The lower power mechanism is mounted on the lower plate and connected with the lower pressure plate so as to drive the lower pressure plate to move up and down relative to the lower plate. Its hemming steps include: placing the board on the lower board; making the upper pressing board move downward and press against the board; raising the lower pressing board, and during the ri...
