CNC Hydraulic Press Brake Bending Machine WE67K

Machine Introduction

WE67K CNC hydraulic press brake bending machine is a high-precision plate forming machine specially used to bend metal plates into various geometric cross-section shapes in a cold state. This machine mainly consists of a bracket, a worktable and a clamping plate. Its core technology is to use electromagnetic force to clamp and form metal sheets to achieve precise bending operations. WE67K CNC press brake bending machines are widely used in various industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles. They are especially suitable for processing complex and side-walled sheet metal parts.

The machine is easy to operate and can be quickly adjusted to specific workpiece requirements, while the electromagnetic clamping method provides greater flexibility and a wider range of applications. With the development of industrial automation and intelligence, CNC press brake bending machines play an increasingly important role in modern sheet metal forming processing, effectively improving production efficiency and processing quality.

As a precision industrial production machining equipment, CNC hydraulic press brake bending machine’s efficient and accurate performance benefits from the coordinated work of multiple precision components.

Synchronization system: The synchronization system of CNC hydraulic press brake bending machine consists of torsion shaft, lower swing arm and joint bearing. The core function of this system is to ensure the synchronization and accuracy of the machine during the bending process. The role of the torsion shaft is to transmit power and ensure that the bending at both ends is synchronized, while the lower swing arm and the joint bearing are responsible for the stability and accuracy of the mechanical action. In addition, the position of the mechanical equipment stop is adjusted by the electric motor and precisely controlled through the CNC system, thus ensuring high accuracy of the bending angle and position.

Guide rail slider part: This part is mainly composed of guide rail slider, hydraulic cylinder and mechanical stop adjustment structure. Driven by the hydraulic system, the hydraulic cylinder pushes the piston rod, which in turn drives the guide rail slider to move left and right on the set track. This design makes the bending pressure of the bending machine more stable and uniform, and also improves the flexibility and response speed of the operation.

Stopper mechanism: The main function of the stopper mechanism is to ensure the positioning accuracy of the material before bending. It is driven by a motor and drives two ball screws to move synchronously through a chain. The CNC system controls the size and position of the stoppers to ensure accurate positioning of the material during the bending process.

Operation console part: The operation console is the human-computer interaction interface of the CNC press brake bending machine. The operator controls the main movements of the press brake bending machine through the button box, including the forward, backward, left and right movement of the stopper frame. The CNC system controls these moving distances with an accuracy of up to 0.01mm. The operating console is also equipped with a limit switch to ensure the safety of equipment operation.
