The Importance of a Hydraulic Press Brake Control

Hydraulic press brake controls can increase productivity and efficiency while helping prevent operator mistakes that cost companies money.

There are various controllers to choose from and they can be retrofitted onto most Hydraulic Press Brakes. Some advanced controllers even enable users to pre-program ram positions prior to operation - which could prove invaluable for your business.

Controlling the ram

Controlling a hydraulic press brake requires an intricate control system. Such systems utilize PC-based controllers with proportional or servo valves to regulate its hydraulic cylinders, and monitor ram position and angle to ensure accuracy and maintain levelness - these controls are usually utilized on higher tonnage presses.

Servo electric press brakes are another popular choice of press brake. These machines offer quick and efficient performance at lower tonnage limits than traditional hydraulic presses; plus they tend to be less costly.

Accuracy in rams is critical to their efficiency, and should be replaced if they become inaccurate or inefficient. A new ram could save money over time by cutting downtime and scrap costs; retrofitting can improve bending accuracy by upgrading or replacing back gauge controls; increasing production rates by increasing bends per hour.

Controlling the back gauge

Controlling the back gauge of a press brake is essential to producing accurate bending results. A closed-loop control system regularly monitors machine output and compares it with expected values to generate a deviation signal that can then be used to correct machine output, saving both time and improving operator productivity.

Programmable controllers make complex shapes and multiple bends simple to program in sequence, saving money by decreasing hydraulic changes and operating costs.

Hydraulic cylinders are conveniently positioned near the rear of the machine for fast and convenient fluid changes. Quick-release tool holders make it simple to switch punches or dies for different jobs as necessary. Safety light curtains automatically open whenever there is an instrument change to prevent people from entering its area while it operates.

Controlling the crowning

Controlling the crowning of a press brake can enhance its accuracy and precision when bending thicker, high-tensile-strength materials, or longer lengths of material. Crowning systems work by applying opposite forces against any deflection of the ram or workbench caused by heavy loads; typically this consists of cylinders installed within the bed of the machine that create an upward thrust against it when under load.

However, some systems utilize a wedge-style crowning system that is manually adjustable by an operator and more cost effective than full hydraulic or CNC wedge-style crowning systems. Press brake control software also automatically determines how much crowning to apply based on material thickness, die opening size, bend length and deflection properties of your specific machine - with some systems even offering offline programming capability so engineers can pre-program jobs prior to sending them over for execution by operators - thus eliminating operator error and increasing productivity.

Controlling the pressure

Press brakes have long been used in sheet metal bending applications, yet their sophistication continues to advance over the centuries. Today's machines offer 12 or more programmable axes of movement and can calculate optimal settings based on materials being used and their dimensions; additionally they display graphic representations of end results, significantly cutting set-up time.

Press brakes can also benefit from retrofits that enhance their functionality, such as installing a ram programmability control to convert an existing hydraulic system into a computerized machine allowing different positions and speeds for programming the ram, increasing productivity and accuracy.

Service personnel must adhere to proper procedures in order to prevent accidents from happening, using tools like multimeters to test electrical continuity of control wiring - this ensures proper machine functionality while protecting workers from injury.
