Description

Technical Parameters

Feature

1. The connecting rod is connected to the transverse axis of the slider, effectively eliminating the eccentricity caused by mold damage in multi station mold production, ensuring the concentricity and standard accuracy of multi station products.

2. Equipped with a mechanical top material structure, it eliminates the problem of multi station molds that cannot be solved by multi station top materials. The product can be freely adjusted at any angle and height to ensure that the forged product stays in the mold and damages the mold, reducing mold damage and extending mold life.

3. Fully intelligent PLC control, electric mode adjustment, overload hydraulic protection; Variable frequency adjustment and automatic oil cut-off alarm device; Electronic digital display module with high memory function, optional hydraulic locking and lifting automatic device.

What Is Press Braking?

Press braking, or brake forming, is a metal deformation process that bends sheet or plate metal along an axis using a press brake machine, clamping the metal between a punch and a die set. The process involves repeatedly driving the mold bending through the driving system. The upper die of press braking has different angles, and the lower die is generally V-shaped or U-shaped.

Factors affecting bending include the tensile strength of materials, precision and strength of tooling, tonnage, bending radius, stroke, back gauge distance, speed, and more. These factors influence the sheet metal's springback and the accuracy of the final profile. Similar to stamping, press braking cannot manufacture long parts.

1. Advantages of Press Braking

- High efficiency for small and short workpieces.

- Convenient operation and setting, requiring only the replacement of top or lower dies for different shapes and angles.

- Lower costs and higher efficiency compared to roll forming and stamping.

2. Disadvantages of Press Braking

- Tolerance is not as strict as roll forming, affecting final profile accuracy.

- Suitable for small workpiece manufacturing in small batches.

- Limited length of the press brake and requires repeated adjustments.

- Higher requirements for operator skills, involving various bending methods like air bending, bottom bending, and coining.

3. Practical Application Examples

- Automotive Industry: Manufacturing components such as brackets, chassis, and structural parts.

- Aerospace Industry: Shaping materials like aluminum and titanium alloys for airplane wings and fuselages.

- Construction Industry: Fabricating structural components for buildings, such as beams and columns.
