Definition, working principle and selection guide of hybrid press brake

With the acceleration of intelligentization and greening of manufacturing industry, more and more enterprises are paying attention to hybrid press brakes. Can they help enterprises realize the upgrading of production? Next, this article will discuss the innovative value of hybrid servo press brakes in promoting the sustainable development of manufacturing industry from the aspects of its technical principles, performance advantages, cost recovery ratio and selection skills.

Definition of hybrid press brake

Definition

Hybrid servo press brake machine is a combination of hydraulic and electric technologies. While retaining the large tonnage and stability of the hydraulic system, it reduces fuel and power consumption through hybrid technology, and drives the electric servo motor to achieve high-precision and high-efficiency bending work.

Differences from traditional press brakes

Energy efficiency: Compared with the traditional press brake that operates with a constant pump push, the hybrid servo press brake uses a servo motor to control the hydraulic pump group, which significantly reduces fuel and power consumption, has less noise, and can effectively reduce the hydraulic oil temperature and the loss caused by long-term operation of the machine.
Working: Traditional hydraulic press brakes are cumbersome to adjust and complex to manage hydraulic oil, while hybrid models are more compact and easy to maintain.

Working principle of hybrid press brake

Mechanism combining hydraulic and electric technologies

Compared with the continuous circulation of traditional hydraulic systems, the hybrid type only starts the pump group when in motion and outputs hydraulic pressure. There is almost no energy consumption when idle or on standby, achieving all-weather energy saving. At the same time, the dual servo pumps work together to achieve accurate supply of bending pressure and rapid return.

Energy conversion and efficiency improvement methods

significantly reducing energy consumption during standby (saving up to 60%).
Eliminate ineffective hydraulic circuit operations, avoid system heating and oil aging.

Advantages of hybrid servo press brakes over traditional hyd press brakes

Energy saving performance

Energy saving can reach 50%-70%, only supplying energy during actual action, and effectively reducing the cost of refrigeration and oil renewal.

Bending accuracy and repeatability

Servo technology combined with digital closed-loop control stabilizes output pressure, and bending and repeated positioning accuracy are greatly improved.

Working speed and production efficiency

The bending action has fast response, high-speed descent, and fast return, which is suitable for batch sheet metal processing and production.

Maintenance and use cost

There is no high temperature and high pressure problem of traditional hydraulic system, and the oil volume is reduced by 80%, so the oil change and maintenance cycle are greatly extended.

Typical industry cases

It is the preferred choice for batch production lines of automobile parts manufacturing companies, home appliances (such as air conditioner refrigerator shells, washing machine frames), and sheet metal processing industries, and can achieve precision control of multiple varieties switching industries.

Purchase guide

Key selection parameters

When purchasing, you should consider the appropriate press brake tonnage, bending length, precision control, tool compatibility and back gauge function, and evaluate the intelligent operation level of the supporting control system.

How to choose according to industry needs

Large-volume production lines can choose models with a high degree of automation, while small and medium-sized manufacturing companies need to pay attention to the ability of flexible bending and fast tool change.

In addition, when purchasing, you need to pay attention to the press brake manufacturer’s industry certification, after-sales service and maintenance convenience.

User value and investment return analysis

Energy saving cost calculation

Depending on the scale of the number of machines owned, the annual energy consumption cost of the hybrid press brake can save thousands to tens of thousands of dollars: among which fuel consumption can be saved by more than 80%, the total cost of ownership (TCO) of the equipment can be reduced by 10-20%, and the risk of maintenance and downtime is also significantly reduced.

Benefits brought by increased production capacity

Product life cycle and maintenance advantages

The hybrid servo press brake adopts a servo system and modular structure, with a long equipment life cycle, low daily maintenance pressure, and very little fuel consumption. It is a long-term investment with high return on investment.
