The sheet to be formed is placed on the CNC press brake, the upper mold is lifted by the oil cylinder, the slider is slid to the appropriate position, and then the upper mold is lowered to the desired position. On the formed sheet, the metal is bent and formed by applying force to the bending lever on the bending machine. Sheet Metal Panel Bender<\/p>\n\n\n\n

Como as pessoas t\u00eam requisitos cada vez mais altos para a precis\u00e3o de folhas de dobra<\/a>, most factories have begun to choose CNC press brake instead of hydraulic bending machines. Sheet Metal Panel Bender<\/p>\n\n\n\n

Because the CNC press brake has fast speed, high precision, more convenient operation, and more in line with modern requirements. Sheet Metal Panel Bender<\/p>\n\n\n\n

In the bending process, we usually can use the following bending methods Sheet Metal Panel Bender<\/p>\n\n\n\n

Point contact bending Sheet Metal Panel Bender<\/h4>\n\n\n\n

As shown in the figure, by using points A, B, and C to make the material and the mold contact and bend, point contact bending is called a typical floating bending, the reason is that it is not completely pressed to the bottom, in the state of contact with air Make a bend. Sheet Metal Panel Bender<\/p>\n\n\n\n

The characteristic of this bending is that the bending angle can be processed freely. For example, using a 30\u00b0 mold for bending, it can process any angle between 180\u00b0 and 30\u00b0. The most suitable V-width for point contact bending is 12-15 times the plate thickness. Sheet Metal Panel Bender<\/p>\n\n\n\n

Ordinary bending is also called close bending, and the English for close bending is bottom. The term “press to the bottom” and “bottom contact” are commonly used in workshop terms, and they are widely used because they can obtain better bending accuracy with less pressure.

Flex\u00e3o de cisalhamento<\/h4>\n\n\n\n

A etimologia de flex\u00e3o de cisalhamento \u00e9 (moeda), o que significa \u201cfabrica\u00e7\u00e3o de moedas\u201d \u00e9 um m\u00e9todo de processamento muito preciso. O objetivo de cisalhamento e dobra \u00e9 obter boa precis\u00e3o, R interno extremamente pequeno e 5-8 vezes a TON necess\u00e1ria para dobra comum.<\/p>\n\n\n\n

O problema da flex\u00e3o de cisalhamento<\/h5>\n\n\n\n

\u30fbPor causa da press\u00e3o mais alta, tamb\u00e9m \u00e9 necess\u00e1rio um equipamento de dobra maior.
\u30fbO molde se desgasta rapidamente.
\u30fbTamb\u00e9m existem restri\u00e7\u00f5es aos moldes. (Use um molde maior resistente \u00e0 press\u00e3o)<\/p>\n\n\n\n

\u00c0s vezes, outras formas de dobra tamb\u00e9m s\u00e3o usadas, geralmente as seguintes<\/h4>\n\n\n\n

flex\u00e3o em L<\/h5>\n\n\n\n

As dobras em L s\u00e3o divididas em dobras de 90\u00b0 e n\u00e3o de 90\u00b0 de acordo com o \u00e2ngulo, e sua nomenclatura \u00e9 baseada no \u00e2ngulo interno ap\u00f3s a conclus\u00e3o. O coeficiente de deforma\u00e7\u00e3o de flex\u00e3o de 90\u00b0 \u00e9 0,4 vezes a espessura do material<\/p>\n\n\n\n

Na forma\u00e7\u00e3o de dobras em N, diferentes m\u00e9todos de processamento s\u00e3o adotados de acordo com os valores de tamanho de comprimento e altura. Um \u00e9 diretamente dividido em duas dobras, e o outro \u00e9 adicionar juntas para dobrar e achatar reversos. Geralmente, o H em N-fold \u00e9 o tamanho mais importante.<\/p>\n\n\n\n

A dobra em Z tamb\u00e9m \u00e9 chamada de diferen\u00e7a de quebra. De acordo com o \u00e2ngulo de forma\u00e7\u00e3o, ele \u00e9 dividido em quebra de borda reta e quebra de hipotenusa.<\/p>\n\n\n\n

O m\u00e9todo de processamento \u00e9 baseado na altura de quebra. A quebra de borda reta \u00e9 usada quando a altura de quebra h \u00e9 inferior a 3,5 vezes a espessura do material. Molde diferencial ou moldagem f\u00e1cil, quando a espessura do material \u00e9 maior que 3,5 vezes, o normal \u00e9 um positivo e um reverso duas dobras.<\/p>\n\n\n\n

A quebra da hipotenusa Quando o comprimento da hipotenusa l \u00e9 inferior a 3,5 vezes a espessura do material, o molde diferencial ou molde f\u00e1cil \u00e9 usado para formar, maior que 3,5 vezes completo<\/p>\n\n\n\n
