Problems solved by technology

With this structure of the rotating shaft type flipping and flanging device, when flanging the sheet material at any angle, it is necessary to replace the flipping body with a fan-shaped notch in the cross-section at different angles, and when flanging, the angle of the section of the upper platen close to the flipping body will be changed. Affect the effect of hemming. When it is necessary to hem the larger width of the sheet, because the distance between the two limit blocks set on the sliding body is fixed, it is impossible to position and fix the larger width of the sheet. Hemming, the rotating shaft type flipping hemming device of this structure needs to use the upper power mechanism and the lower power mechanism, the structure is complicated, the operation is troublesome, and the production cost is high

Abstract

The invention discloses an edge folding method and an edge folding device. The method comprises that panel veneer is placed on a main working panel, and is located by using an adjustable locating frame; the rocker arm of a turn over mechanism drives a working pressing plate to rotate, and a main working pressing plate presses on and bends the panel veneer in a rotating process to achieve edge folding; and a turn-over mechanism carries out reset turning over to enable the main working pressing plate to reset. The edge folding device controls the edge folding angle of the panel veneer by controlling the air pressure of an air cylinder, and can carry out edge folding to panel veneer with different width. The edge folding method and the edge folding device further have the advantages of being simple in structure, convenient to operate, low in production cost and good in folding effect.

Description

technical field [0001] The invention relates to a hemming method and a hemming device for arbitrarily folding a sheet material within 180 degrees. Background technique [0002] The hemming device is to fold the sheet material instead of manual operation. The existing hemming device, such as the Chinese Patent Application Publication No. CN102009094A, is a shaft-type overturned hemming device, which includes an upper device and a lower device. , the upper device includes an upper plate, an upper pressure plate and an upper power mechanism; the upper power mechanism is attached to the upper plate and connected to the upper pressure plate, so as to drive the upper pressure plate to move up and down relative to the upper plate; the lower device includes a lower plate, a flip combination device and a lower power mechanism; the flipping combination device includes a sliding body and a flipping body pivotally connected to the sliding body, and the flipping body is provided with a g...
