CNC Press Brake Bending Machine

RAYMAX NC and CNC press brake realize the bending function by controlling the back gauge and slide stroke. When using a CNC hydraulic press brake, you only need to enter the number of pieces required for bending, the bending angle and the corresponding bending angle of each step, and the CNC press brake will complete the bending according to the data you set.

CNC Metal Press Brake & NC Press Brake

Compared with CNC press brake, NC press brake requires the operator to adjust the bending angle based on experience, which requires a running-in process. And the current driving modes of the bending machine are mechanical, pneumatic, hydraulic, and servo-hydraulic, but RAYMAX only chooses the most advanced driving mode of the latter two. CNC press brake equipped with elctro-hydraulic servo system to control left and right side of cylinder . Also have standard grating ruler to calculate angle accurately through CNC system . In order to improve production efficiency and reduce labor cost, RAYMAX factory provide fast quick clamp for CNC press brake . Besides , press brake’s backgaue can be extend to total six axis . Worktable compensation can be controlled through controller , more convenient and accurate for our client .

Press Brake Design&Construction

The main components of CNC hydraulic bending machine include hydraulic device, control panel, controller with automatic feeder, backing plate, plunger and frame. Below we will describe some key components.

Benches and pillars

The workbench is composed of a base and a pressure plate. It is connected to the splint by a hinge. The column is a part of the frame that supports all the components on the machine. The workpiece is bent on the worktable.

Pressure plate

The pressure plate (or backing plate) is installed on the base. Equipped with a mold cushion, the plate allows the bending machine to apply reverse tension. The metal sheet is fed between the backing plate and the indenter guide rail, and is formed by the upper mold and the lower mold.

Plunger/sliding guide

The indenter is the part where the upper mold is installed and drives the mold to press on the workpiece. The pressure of the punch is controlled by the numerical control system. The type of drive determines the press process when the indenter is running. Rigid guidance and correct control are the key to prolonging the service life of CNC hydraulic press brakes.

Controller and feeder

Generally, CNC bending machines use automatic feeders to consistently feed raw materials into the forming area. The material is processed by other machines such as decoiler, sheet metal straightening machine, etc. before loading.

Working Principle of Press Brake

Brake molding usually molds metal up to 10″ thick, and some equipment can mold parts up to 20 feet. The bending angle can also be precisely controlled by adjusting the depth of plunger movement. The plunger is lowered to press against the supporting metal plate. It. Upper and lower mold. When force is applied to the metal plate, it will change its shape according to the design of the mold.

Press Brake Advantages

Due to its simple design and working principle, the hydraulic CNC bending machine has many advantages. They are easy to operate, efficient, economical and versatile. Let’s take a look at its advantages.

Use-friendly operation

CNC bending machine is a simple and easy-to-use equipment. They are digitally operated machines that even semi-skilled operators can easily program and quickly produce all necessary components. Because the controller guides the user in a phased process, inexperienced operators can use the machine correctly.

Flexible CNC programming

Modular programming can help users set up equipment. Once the appropriate operation is selected, another series of options related to the manufacturing process (cycle time, bending, flange length, stress, etc.) will appear on the panel. After setting the variables, these values will be displayed on the screen and the device can be operated.

Multitasking and energy saving

This is a multitasking system that only requires an operator to check the first component while processing the program related to the second part. Other operators can perform programming or other tasks at the same time. In terms of system configuration, it is energy-efficient.

When the sliding guide is empty, no power is consumed. Hydraulic pumps and motors are components that require continuous power supply. The CNC system guarantees efficient power transmission. The slider helps provide fast and accurate pressure, further reducing energy consumption.

Structural integrity

Compared with other forming processes that require parts and heat to be fused together, the bending machine does not need to be heated and melted to complete the task. This reduces cycle time while providing the same (sometimes better) structural integrity of the part. This advantage also significantly improves overall productivity.

Versatility

The CNC hydraulic bending machine offers a variety of shapes and can freely bend metal plates at almost any desired angle. In addition, it can also handle various types of metals. The CNC system ensures high-precision various bends and unique structures, and can be precisely adapted to a variety of applications.
