Sheet metal bending Machine for sale

What is Sheet metal bending? Bending is an important process in sheet metal fabrication. Sheet metal bending is used for bending steel plates to form shapes. The Sheet metal bender machine is used in metal fabrication such as construction, automotive, and manufacturing, and for creating components like brackets, enclosures, and more.

working Principle  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.

 

Sheet Metal Bending Machines Types

The Sheet metal bending machine includes a hydraulic sheet metal bending machine and a 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 workpieces for bending. It can be moved and positioned to allow press brakes 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 assure bending accuracy and sheet protection:

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

 

What are the types of sheet metal bending?

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 processes consist of sheet metal bending types in different shapes, 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 to produce electrical enclosures, medical equipment, and intricate components.

Roll Bending:

Roll bending uses a roller to curve the metal sheet for curved or cylindrical shapes. It is used in the production of pipes, tubes, and structural components.

Roller sets are central in the use of this method capable of creating different cross-section profiles with numerous curves. 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 controls bending angles and is applied in the automotive, aerospace, and electronics industries.

U-Bending:

U-shaped bends 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. 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. This technique uses a supporting mandrel internally to stop the bent sheet metal part from creasing.

 

Benefits of sheet metal bending

• Increased Accuracy: Given the precise determination of the k-factors and bend allowance.
• Increased Productivity: The bending processes require less tooling and can support automation.
• Less Secondary Procedures: The bending process does not require secondary processes for completion such as cutting.
• Low Tooling Cost: Employ simple tooling to undertake the bending processes resulting in an 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.
