La diferencia entre doblar y plegar

Bending And Folding

Bending And Folding In recent years, 30% of the sheet metal factories in Europe and the United States and other developed countries have begun to use the folding machine to replace the traditional bending machine for part of the sheet metal bending. Compared with the bending machine, the folding machine is a bending equipment with many advantages, which is more convenient to operate. In this paper, making a simple introduction bending machine and folding machine, the figure below is the difference between the working principle of bending machine and folding machine.

Bending machine is divided into hydraulic bending machine and CNC bending machine, according to the mode of motion can be divided into up and down. According to the synchronous mode, hydraulic bending machine can be divided into torsion shaft synchronous and electric hydraulic synchronous. Bending And Folding

Numerical control bending machine realizes the bending function by controlling the slider stroke and back stop of the bending machine. When using CNC bending machine, as long as the part drawing of the work piece and the bending angle of each step are input, the bending machine will be realized one by one according to the input steps. The advanced CNC bending machine mainly adopts electric hydraulic servo system and grating ruler to form full closed-loop control, with high synchronous control precision, bending precision and repositioning precision.

In use, the CNC bending machine can be operated flexibly, which can realize the super long plate processing by double machine linkage, and can process parts by single machine operation. This not only improves the use efficiency of the bending machine, but also reduces the energy consumption. The bending machine comprises a bracket, a worktable and a clamping plate. The worktable is composed of a base and a pressing plate and is arranged on the bracket; The base is composed of a base shell, a coil and a cover plate, which is connected with the clamping plate through a hinge.

The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is electrified by the wire, and after being electrified, the pressing plate is attracted, so as to realize the clamping of the thin plate between the pressing plate and the base. The bending machine can meet the needs of various work pieces by replacing the bending machine mold. Bending And Folding

• Working characteristics of bending machine Bending And Folding

1. The requirements for operators are relatively high and the operator is required to position the bending flange. Bending And Folding
2. The operator must hold the material. Bending And Folding
3. The side with large material area is placed outside the bending machine. Bending And Folding
4. For the bending of large work pieces, it is difficult for one operator to complete, which requires two or more people to work at the same time. Bending And Folding

• Determinants of bending angle of bending machine Bending And Folding

1. Stroke of slider. Bending And Folding
2. Mold size. Bending And Folding
3. Change of material thickness. Bending And Folding
4. The quality of supporting materials for operators. Bending And Folding

Folding machine is a simple bending machine, divided into manual folding machine and pneumatic folding machine. Bending And Folding

Folding machine is a kind of machine to process the edge of products. It is used to produce stainless steel sheet products with simple shape in a large scale. However, with the continuous updating and maturity of technology, these products are produced by cold bending punch. The folding machine uses the model with bending radius to fix the steel plate on the worktable of the machine tool, and the protruding part of the material is placed on the movable worktable, which can rotate along the center of the bending radius. Bending And Folding

When the movable table rises, the stainless steel can be bent to the required angle. When bending, because the stainless steel will slide on the worktable, in order to prevent material scratch, on the one hand, the worktable surface should be smooth, on the other hand, a layer of plastic film should be pasted on the stainless steel surface to prevent work piece scratch. The upper beam of the folding machine is usually made into a wedge to form a gap, so that the blank with proper shape can be folded into a quadrilateral box or groove. Typical legend of folding machine is shown in the figure below. Bending And Folding

1. Los requisitos técnicos para los operadores no son altos.
2. En el proceso de plegado, la hoja se coloca en la mesa de tope trasero para asegurar la distancia de plegado y sujetar la hoja. En el modo manual, la seguridad del operador de la máquina plegadora mejora considerablemente.
3. Small plate thickness error will not affect the bending accuracy. Bending And Folding
4. La máquina plegadora también se puede plegar en un espacio muy pequeño, y el plegado de diferentes espesores de placa no necesita cambiar el molde, por lo que tiene ciertas ventajas en el plegado de grandes arcos.
5. Small edge width, low cost. Bending And Folding

1. Before operation, wear tight protective clothing, fasten the cuffs, keep the lower hem of the jacket open, and do not wear, take off or change clothes beside the machine tool, or put cloth around the body, so as to prevent the machine from wringing. Must wear a helmet, braids should be put into the hat, not to wear skirts, slippers. Bending And Folding
2. Los trabajadores de plegado deben tener un cierto estudio profesional, comprender la estructura y el rendimiento de la máquina herramienta que operan e instalar correctamente el molde, para que puedan operar de forma independiente.
3. Add lubricating oil before use, and check the empty car for two minutes. Bending And Folding
4. Después de arrancar, debe esperar hasta que la velocidad de funcionamiento sea normal; Al mismo tiempo, observe la dinámica del personal circundante para evitar lesiones.
5. Do not use the machine beyond the specification. Bending And Folding
6. Welding scar and big burr are not allowed on the material to prevent mold damage. Bending And Folding
7. Cuando la pieza de trabajo se voltea o se mueve hacia adelante o hacia atrás, los operadores de ambos lados deben mantener un contacto cercano y actuar de la misma manera.
8. Después del trabajo, corte la fuente de alimentación, haga un buen trabajo en el mantenimiento de la máquina y la limpieza ambiental.

• Principio de funcionamiento de la máquina plegadora

La pieza de la viga superior generalmente tiene forma de cuña para formar un espacio, de modo que se pueda doblar en una caja cuadrilátera o en una ranura con un espacio en blanco de la forma adecuada.

La máquina plegadora se utiliza a menudo para producir una amplia gama de productos de chapa galvanizada o acero inoxidable de forma simple, pero estos productos se producen principalmente mediante punzón de plegado en frío.

• Aplicación de la plegadora en Industria de conductos de aire HVAC

La máquina plegable se divide en máquina plegadora plana y máquina plegadora de placas en la industria de tubos de ventilación. La máquina plegadora de borde plano se utiliza para la formación de placas plegables, y la máquina plegadora de placas común adopta un troquel dentado, que se utiliza principalmente para la formación de plegado de conductos de aire cuadrados con brida de placa común.

La optimización del proceso de producción general es el deseo de toda empresa, porque la optimización del proceso de producción puede, en última instancia, lograr la reducción de los costos humanos, la mejora de la eficiencia del trabajo y la precisión de la calidad de la producción. Por lo tanto, con la profundización de la comprensión de la gente sobre la máquina dobladora y la máquina plegadora, la orientación y el uso correctos de la máquina plegadora en la industria de la chapa metálica es una dirección de mejora del proceso de doblado. Y cómo elegir el equipo de plegado adecuado depende de la aplicación de la máquina y del grosor del material, etc.
