What is an CNC Hydraulic Press brake?

CNC hydraulic press brakes is a huge cold forming machine made to ensure precision in metal forming. They bend sheet metals to create the desired profile. Some models can produce up to 4000 tonnes of force for bending. A normal press is ranging from 4 to 30 feet.

Design & Construction

The most important components in a CNC hydraulic press brake comprise the hydraulic unit as well as a control panel an electronic controller, an automatic feeder, a bolster plate, an ram, and the frame. Here are a few of the key elements.

Column and bench

The base and press plates form the work bench. The clamping plate is connected to the workbench via an articulation hinge. The columns are component of the frame that helps support all the other components on the machine. The workpieces are bent on the workstation.

Plate

The press plate (or bolster plate) is positioned on the base. The plate is equipped with die cushions that allow the press brake to apply counter-draw force. The sheet metals are pushed between the bolster plate, ram guide as well as the lower die for shaping.

Guidance for Ram/Slide

The ram is where the upper dies are attached which causes the dies to press against the workpiece. The CNC system controls the pressing force of ram. The ram's movement is controlled by the type of drive. The most important factors to prolong the time span for the CNC hydraulic press brake are a firm guidance and proper control.

Controller and Feeder

In general CNC press brakes utilize automated feeders that continuously deliver the raw materials to their forming zone. Prior to being loaded, the components are treated by other machines, such as the decoiler as well as the sheet metal straightener.

Working Principle

Brake shaping typically molds metals that are up to 10" thick and some equipment can create parts as wide as 20 feet. The bent angle can also be controlled precisely by controlling the speed of the ram's movement. The lower die is used to hold the sheet of metal, which is held by the ram. As the force is applied to the sheet metal it alters its shape according to the design of the die set.

Benefits

A CNC hydraulic press brake offers numerous advantages due to its simplicity of layout and operation. They are simple to use and cost-effective, flexible and efficient. Let's examine some of the benefits.

User-friendly Operation

CNC press brakes are an easy and user-friendly device. They are programmable and can be produced quickly even by semi-skilled employees. Since the controller guides the user in a stage-wise process, it's feasible for an inexperienced user to operate the machine in a proper manner.

Flexible CNC Programming

Modular programming assists the user to set up the unit. After selecting the right option, the panel shows an array of options that are relevant to the manufacturing process. These include cycle time along with bending degree, the length of the flange. After the variables are established, the results are displayed on the display. The machine is now ready to go.

Multitasking & Energy-saving

This multitasking system requires one operator to look over and perform work on the component that was inspected. Other operators can work on the programming task or perform other duties simultaneously. In terms of the configuration of the system, it's energy-efficient.

If the slide guide is not in use, it does not require any power. The hydraulic pumps as well as the motor are the components that require a continuous power supply. The CNC system guarantees an efficient power transfer. The slider helps provide quick and accurate presses, which further reduces energy consumption.

Structural Integrity

Compared to other forming processes which require the fusion of parts with heat, the press brake can do the job without heating and melting. This speeds up the process and provides the same (sometimes more) structural integrity of the piece. This also significantly increases the overall efficiency.

Versatility

CNC hydraulic press brake can be shaped in many ways and allows you to bend sheet metals in any angle. Additionally, it is able to process various types of metals. The CNC system ensures an array of shapes and bends with great precision, and allows an exact fit for a variety of applications.

Applications

CNC hydraulic brakes can be utilized as sheet metal machine for forming. They are combined with sheet angle cutting machines as well as shearing equipment to create intricate surfaces on sheet metals. The CNC hydraulic press brake is a machine with an impressive forming capacity and accuracy, and is increasingly popular in various industries like transportation, automotive, military energy, aerospace, and energy.
