What is press brake working principle?

The structure of the hydraulic press break includes the bracket, table, and clamping plate. It forms metal bends by clamping the workpiece between press brake dies. By using a matched punch and die tool. The metal plate can be bent several times for one desired shape during press brake operation. The bending press machine is generally narrow and long, so it can bend large metal plates. The bending force is also known as tonnage. Every hydraulic sheet metal press brake has a concentrated load limit in the center of the press. If the press brake operators use the wrong tonnage, It can damage the die or the part.

FAQ- Frequently asked questions

What is a press brake do?

Press Brake is a piece of equipment that is used to bend sheet metal with various shapes. Press brakes work by using a punch and die that are set at predetermined angles to bend or cut metal into a variety of shapes and forms.

What is Air Bending?

Air bending is bending your material past the desired angle and allowing the part to springback to the desired angle. This takes less tonnage than bottom bending. Typically an air bending tool is designed with an additional 5 degrees more than desired angle. Check with JSTMT for more press brake tooling details.

How is press brake tonnage calculated?

The material thickness value is squared, multiplied by 575, divided by the die-opening width inch value and then divided again by 12 inches. The tonnage per inch is now calculated. You can then multiply the value by the bend length.

How to fix press brake oil leakage ?

This issue commonly consists of two reasons:

The connecting screw and pipe connector are loose.
The seal is bad.

How to fix this issue:

The most common fixes to this issue are:

Tighten the screw and connecter.
Replace the seal.

Why no bending pressure in the hydraulic system?

The problem:

There isn’t pressure in the hydraulic system.

Cause of the problem:

This problem usually occurs for two reasons:

The orifice and the core of the valve are blocked.
The piston seal on the cylinder leaks.

How to solve the high noise in the high-pressure filter?

The problem:The high-pressure filter gives off high noise.Cause of the problem:This is most commonly caused by a blockage in the high-pressure filter.How to fix this issue:Unfortunately, the press brake bending problems do not have an easy solution. You will need to replace the core of the high-pressure filter.

Why doe the ram step down during pressing down?

The problem:

The Ram steps down during pressing down.

Cause of the problem:

This problem can occur for two common reasons:

The balance pressure in the valve isn’t great enough.
The guide rail is too tight.

How to fix this issue:

This problem can usually be solved in two simple ways:

Increase the balance pressure.
Loosen the guide rail.

Do you provide installation and commissioning?

Yes, after service covered including installation, commission, training at customers’ request. also we support online video installation guide if customer have problem .
