Sheet metal bending Machine for sale

What is Sheet metal bending? Bending is an important process in sheet metal fabrication process. Sheet metal bending is used for bending steel plates to a formed shapes.  The sheet metal bending machine uses a punch and die to bend the metal sheet into various shapes at a fixed angle. It can use a flat square sheet to curve a sheet with the desired angle. This bending operation is subjected to the bending force.

The Sheet metal bending machine is used in metal fabrication such as construction, automotive, and manufacturing, and for creating components like brackets, enclosures, and more.

 

Sheet metal bending types

Bending sheet metal involves the deformation of a metal part. The deformation changes in shapes from a smooth plate to a V shape. The sheet metal bending process involves the bending types of different shapes and applications and advantages.

Bottom Bending:

sheet metal to the bottom of the die can create a sharp bend.  As it overcomes the spring back problem by punch and die force, it provides precise bends in sheet metal works.

Bottom bending is used in the production of electrical enclosures, medical equipment, and intricate components.

Roll Bending:

The Roll bending uses a roller to curve the metal sheet, often used for curved or cylindrical shapes. Roller sets are central in the use of this method capable of creating different cross-section profiles with numerous curves.

It is used in the production of pipes, tubes, and structural components. Roll bending offers high efficiency and accuracy for consistent bends.

V-Bending:

The V bends are often used in the punch and die with a V opening. It has precise control over bending angles and is commonly applied in industries such as automotive, aerospace, and electronics.

U-Bending:

Forms U-shaped bends and are one of the basic techniques in sheet metal bending. It can create channels, U shapes, and rounded edges. U bending sheet metal is widely used in furniture manufacturing and architectural projects.

Coining:

Provides highly accurate, tightly controlled bends, suitable for intricate designs.

Wipe Bending:

Achieves bends by wiping the sheet against a contoured die.

Rotary Draw Bending:

the sheet metal is bent around a rotating die. this technique uses a supporting mandrel internally to stop the bent sheet metal part from creasing.

It is suitable for creating cylindrical or curved shapes, such as tubes, pipes, and rounded profiles. Rotary bending is commonly used in industries like automotive, construction, and manufacturing.

Benefits of sheet metal bending

Increased Accuracy: Given the precise determination of k-factor and bend allowance, the metal bending process is significantly accurate.
Increased Productivity: The bending process requires less tooling and can support automation. You can therefore undertake fast bending operation allowing high volume output.
Less Secondary Procedures: Bending process does not require secondary processes for completion such as cutting which may require welding.
Low Tooling Cost: The bending process employs simple tooling to undertake the process resulting in overall low cost.
Reduce Parts Usage: Bending allows you to furnish a single piece into a desired shape without having to employ many pieces in an assembly.

 

Sheet Metal Bending Machines Types

The Sheet metal bending machine includes hydraulic sheet metal bending machine and CNC sheet metal bending machine.

---

Hydraulic Sheet metal bending machine

The machine is equipped with hydraulic electric control. It can adjust slider travels, inching, semi-automatic, and automatic operating.

The hydraulic system may realize quick and quick decline, working speed, quick return, and sudden stop during work in the process of up and down, etc.

 

CNC sheet metal bending machine

Automatic sheet metal bending machine with CNC controller DA66 for high precision & accuracy. and It can option with the crowning system.

An automatic CNC crowning system for improving sheet metal machines quality.

a servo driven back gauge system for increased speed.

a 3D graphical touch screen to simulate the bending sequence.

Automatic sheet metal bending machine with CNC controlled back gauge

A back gauge is a component used with a sheet metal CNC bending machine to position work pieces for bending. It can be moved and positioned to allow a press brake to create a variety of complex bends.

Ram stroke (Y) and back gauge(X, R, Z) are controlled by the CNC system.
X controls the back gauge to move front and back.
R controls the back gauge to move up and down.
Z refers to back gauge fingers moving left and right.

 

Inclusion: Sheet metal CNC bending machine advantage

CNC sheet metal bending machines differ from the press brake machine in principle and provide superior assurance for bending accuracy and sheet protection:

1. Save Labour, easy-to-operate CNC panel with less labor.
2. Automated precision with high bending techniques, especially for high quality bending profiles with accuracy.
3. High speed, improved machine processing efficiency, and low energy consumption.
4. safety operation. Safety camera systems not only provide a point of operation safeguard but also help ensure that the correct tooling is being used.
