After more than a decade of iterative updates, HAVI’s electro-hydraulic servo control technology has reached a new level. Looking at the entire industry, the deep integration of this technology with press brakes has created a new era and continues to drive the development of the sheet metal fabricating industry.
Compared to traditional press brakes, the WE67K series CNC press brakes demonstrate superior bending accuracy and efficiency, capable of increasing bending efficiency by up to 30% within the same production cycle. Moreover, they can achieve an energy-saving effect of over 25%.
CNC controllers play a crucial core role in the motion control of press brakes. HAVI mainly uses controllers from three mainstream companies in the world, namely Delem from the Netherlands, ESA from Italy, and Cybelec from Switzerland.
Proper tuning will enhance the compatibility between the controller and the machine. By combining our core assembly process with advanced tuning techniques, we can unlock a variety of high-end optional functions for customers to choose from.
HAVI controllers elevate precision and efficiency with features such as instant angle adjustment, comprehensive 2D/3D programming capabilities, and advanced multi-axis control, guaranteeing uniform excellence in output.
Back-gauge
The HAVI back-gauge system is at the forefront of the press brake industry with its excellent motion accuracy.
We use imported ball screws and linear guides, which improves the accuracy and consistency in the production process of HAVI’s CNC series press brakes.
Our entire frame of back-gauge system undergoes high-temperature tempering treatment to eliminate internal stress, improve metal plasticity and toughness, and prevent precision loss caused by frame deformation.
In terms of stop fingers, we have designed and applied a synchronous pulley mechanism controlled by a servo motor, which provides better control performance and accuracy for the CNC press brake machine’s back-gauge system.
Servo Motor
Servo motors have become the dominant technology in the field of industrial automation. It achieves high dynamic performance and improves machine production efficiency through low energy consumption, becoming the preferred choice for many enterprises. Compared to traditional motors, using servo motors can save up to 35% of energy, helping customers significantly improve efficiency and reduce operating costs in the production process.
In addition, we also provide high-efficiency energy-saving motors from Siemens in Germany to meet customers’ regular production needs. The efficiency of these motors is much higher than that of standard motors, significantly improving work efficiency. They adopt advanced technology and design to ensure stable and reliable performance under various working conditions. Whether running at high or low speeds, these motors can maintain excellent efficiency and accuracy, meeting customers’ high requirements for production efficiency and product quality.
Punch & Die Tools
Prior to initiating an order, it is essential to deliberate on the appropriate press brake punches and dies. Selecting the correct combination of punch and die is vital for attaining the desired bend configuration. Our offerings include tailored tooling solutions that align with the precise bending specifications provided by our clients.
Ball Screw & Guide
Our equipment is equipped with ball screws and linear guide rails, guaranteeing seamless and trustworthy performance on operation. The cooperation with well-known brands from Japan and Taiwan, China has ensured the stability of the motion control of our press brake.
Crowning System
HAVI has long been deeply involved in the field of press brake crowning compensation systems, adhering to independent R&D and production. Currently, we have two product lines: electric lower crowning compensation systems and a complete set of upper and lower hydraulic clamping and crowning.
Our self-designed system calculates compensation values based on the overall deformation of the slider and workbench. This seamlessly aligns the deformation curve of the slider with the compensation curve, ensuring that the straightness and angle consistency are always maintained during the production and processing of our press brake products.
Not only does it occupy a large market share in the domestic market, but it is also exported to many countries around the world. At the same time, our deep strategic cooperation with Dutch manufacturer Wila enables us to provide customers with more high-end optional options, especially for the European and American customers.
