Hydraulic press brakes are more flexible and have a higher capacity than mechanical ones because hydraulic brakes are controlled through fluid pressure to a piston. The use of pressurized fluid allows you to program different strokes and speeds within a stroke as needed. Depending on the cylinder length, stroke lengths up to 250 cm or 100 in can be easily obtained in hydraulic press brakes. The number of strokes can be as high as 600 per minute, as it is in the case of a high-speed blanking operation.
You have three types to choose from: conventional, NC, and CNC. In conventional machines, the stroke length and speed are manually adjusted, which means that the operation is based on the operator's experience and knowledge. In NC machines, a program is feed through the NC controllers, which are fitted to the hydraulic press brake. These programs control the machine parameters. NC machines feature speedy stroke cycles for all jobs as well as a reduced setup time. Therefore they are extremely well suited for this kind of repetitious job. In CNC machines, the computer fed program exclusively operates the hydraulic press brake. Bulk pressing operations are possible with these hydraulic press brakes by changing the parameters of the program on the computer.
For operation in the United States, hydraulic press brakes have a 50,000-ton maximum capacity. This is a far greater capacity than mechanical press brakes, which can only handle up to 18,000 tons. Since hydraulic press breaks can have multiple cylinders, it is possible to apply the programmed load entirely to the main ram while applying separate force and timing to the blank holder.
The number of rotating components is minimized on the hydraulic press brake, resulting in less need for maintenance. The machine has hydraulic fluid, which acts as a lubricant, circulating through it. Because the fluid keeps the machine continually lubricated, there is less wear on the components; this means less time and money spent on maintenance. The welded steel frame provides strength and rigidity, reducing vibration. You'll find modern hydraulic press brakes much quieter and easier to adjust.
The piston, cylinder, and guide ways are the only sliding parts of a hydraulic press brake. In addition, wear-and-tear resistant materials are used in hydraulic press brakes. Lubrication also helps reduce the damage.
Adjustable slanting wedges are installed on top of the hydraulic press brake. Manually controlling the accuracy of the job to be pressed is simplified by the ability to adjust these wedges. It is possible to adjust the piston stroke by utilizing the electric motor by the hand wheel. The indicator shows the length of the stroke.
Safety guards on the hydraulic press brake mean operators don't have to worry about safety issues. Hydraulic press brakes are in compliance with safety regulations at almost any machine shop and factory since they have a high capacity and can be adjusted easily.
Make A Hydraulic Press
One of the biggest advantages of a hydraulic press over its mechanical counterpart is that a hydraulic press has a unique ability to provide full tonnage (or pressing power) throughout the entire range of the stroke. Mechanical presses usually only apply full force near the end of the stroke. This allows for much more flexibility with a hydraulic press.
As a hydraulic press owner, you will also enjoy increased customization in configuration and operation. Mechanical presses tend to offer only standard sized beds and tonnage. In contrast, a hydraulic press can be easily customized for a customers needs - whether it is a large bed with low tonnage - or the opposite - a small bed with high tonnage. This is important for highly customized jobs and special needs.
Customization also extends to areas that require job-by-job basis customization. As an operator uses a hydraulic press and becomes intimately familiar with its details, they can adjust tonnage and reduce ram movement that might be unnecessary. This can result in reduced job time and less wear and tear on a press when these things are customized on a job-by-job basis.
Some shops need a hydraulic press to perform one simple task well, whereas others might need a system that performs many tasks for a variety of jobs. The beauty of the hydraulic option is that these customizations and configurations are relatively easy to make.
The upfront cost and long term ROI is much more reasonable with a hydraulic press. They use simple, easy to obtain parts. Mechanical presses often have many custom made items that can be expensive, labor intensive, and may be unproven and require frequent service.
Hydraulic relief valves on a press mean that no matter what, a press cant exceed its maximum allowable pressure. This is a safety feature that can and has saved hydraulic presses on many occasions.
From PCs to PLC control systems, hydraulic presses have virtually limitless control options. This allows hydraulic presses to perform a wide range of jobs, store settings, and allow for precise pressure and positioning throughout the RAM force and even direction can be controlled.
Hydraulic presses provide the largest amount of pressure for the amount of space they take up to operate. Some estimates claim that hydraulic presses take up half the space a mechanical press would for the same amount of tonnage capacity.
Because of a hydraulic press ability to have almost exact control over the direction and amount of pressure means that the actual products produced by the press are often of higher quality and precision than their mechanically produced competitors.
Whichever press you ultimately decide to purchase, it is important that it fit your needs precisely. Definitely do your homework, make a list of your requirements, and dont be afraid to ask the tough questions.
