14mm metal sheet bending machine for sale refers to a special machine tool with sufficient bending force, which can stably and accurately bend ordinary metal plates with a thickness of 14mm. Most of these equipment are CNC hydraulic press brake machines, equipped with advanced control systems and servo back gauges. This type of medium and large CNC hydraulic bending machines are widely used in sheet metal processing, machinery manufacturing, steel structures, automotive parts, chassis cabinets and other industries.

1. Main structural components of 14mm metal sheet bending machine for sale

- Body structure: high-strength steel plate welded structure, tempered to eliminate stress, good overall rigidity.

- Slider system: hydraulic drive, upper moving design, the slider moves up and down for bending.

- Mold system: upper mold + V-shaped lower mold, the mold can be replaced according to the thickness and angle of the plate.

- Back gauge system: CNC control, multi-axis linkage, improve positioning accuracy and repeatability.

- Hydraulic system: electro-hydraulic servo synchronous control, high control accuracy, energy saving and high efficiency.

- Control system: common brands such as ESA, DELEM, Cybelec, etc., support graphic programming, automatic compensation, angle correction.

- Compensation device: usually equipped with deflection compensation device to ensure the bending accuracy of long plates.

2. Key configuration description

- Electro-hydraulic servo system

The cylinders on both sides are controlled by servo proportional valves, combined with grating ruler feedback to keep the sliders synchronized with high precision.

The synchronization error is usually ≤±0.01mm.

- CNC control system

Supports graphic programming, automatic bending angle calculation, pressure compensation, etc.

Touch screen interface, intuitive operation, support USB import program.

- Compensation system

Deflection compensation device (hydraulic or mechanical), automatically corrects the deformation of the frame to ensure the consistent angle of the entire sheet.

- Mold system

Equipped with V-shaped multi-groove mold or quick-change mold, suitable for different sheet widths and bending angles.

3. Examples of Applicable Materials

14mm metal sheet bending machine for sale usually refers to medium and large CNC electro-hydraulic synchronous bending machines with sufficient bending force and suitable for processing steel plates up to 14mm thick (such as Q235 carbon steel, stainless steel, etc.). Such equipment is widely used in heavy sheet metal processing, engineering machinery, steel structures, bridge manufacturing and other fields.

- Q235 carbon steel: Q235 carbon steel plate with a full-length bending thickness of about 12 to 14mm

- 304 stainless steel: It is recommended to reduce the length or increase the tonnage

- Aluminum plate: easy to bend, low tonnage requirements

5. 14mm metal sheet bending machine case analysis

In the case of conventional V=8×T lower die slot, we take the 400ton 4000mm electro-hydraulic synchronous CNC press brake in the picture as an example for analysis.

Bending force: 400 tons

Bending length: 4000mm

Sheet material: ordinary steel plate (such as Q235, yield strength is about 250MPa)

1) Reference calculation method

For Q235 steel plate, the simplified empirical formula is as follows:

T = (650 × V) / (σ × L)

Actual bending force F (ton) ≈ (1.42 × σ × T² × L) / V

T = Plate thickness (mm)

L = Bending length (mm)

σ = Material yield strength (MPa)

V = Lower die slot width (generally about 8×T)

2) Actual bending capacity estimation

Analysis table:

If you also want to bend stainless steel or aluminum, the situation will be different. Stainless steel needs to be bent in larger tonnage (because its strength is about 1.5 times higher), while aluminum is relatively easy to bend (low tonnage requirement).

If you have specific usage requirements (such as plate material, length, output, whether automatic loading and unloading is required, etc.), I can provide you with a matching specific model or solution.
