Not all hydraulic presses are created equal, and you need to understand the differences before making a purchase, by doing proper research. Below, we have outlined some important information and considerations that may help you to make the best choice, to meet your job requirements.
Tonnage may be easily adjustable or you can get a specific tonnage for the job. Tonnage can also be customized, if the need calls for a tonnage that falls outside the standard.
Type selection is going to be a direct result of the job requirements. An open-gap press is easily accessible from 3 of 4 sides. If even pressure is a major requirement, then a four column press may be something that may be of interest. A straight-side press is excellent for off-center loading of material.
Accessories are offered by manufacturers and they can include: timers, die cushions, reversible switching, and sliding bolsters, just to name a few of the add-ons available, to make your meeting your needs easier and more efficient.
Quality and durability are two things to consider, when you are deciding to purchase a hydraulic press. Other things to consider, depending on the type of work that is planned to be performed, is the horsepower, maximum available press, speed of the press, thickness of the bolster and the construction of the frame.
Hydraulic presses have a wide range of uses, but are highly recommended for when deep drawing and extruding operations are required.
Some designs of a hydraulic press include: a straight side, C-shaped and an open-rod design. An open-rod design makes it easy to load and unload material, from all sides of the machine.
1. FRAME – securely holds the cylinder and the working area in place.
2. BED – is the flat surface that supports the dies/bolsters.
3. BOLSTER – is the plate that is mounted on top of the bed.
4. The work height is the distance from the bolster to the floor.
5. The main purpose of a heat exchanger is to keep the oil at a proper temperature.
6. Throat clearance describes the distance from the ram to the frame. This distance indicates the area that a piece can be properly centered under the ram.
7. Daylight refers to the area between the top of the bed, to the below the ram (when it is positioned upward). Basically, “daylight” shows the total vertical capacity of the press.
There are a few “stand-out” advantages of owning and working with a hydraulic press:
1. The tonnage is easily adjusted, and this flexibility allows for minimal maintenance on all working parts.
2. Pressure remains constant throughout the entire stroke process.
3. Drawing speeds can be adaptable.
If you are unable to find the exact design and capabilities of a hydraulic machine to meet your needs, remember, that many presses are custom-built to meet the desired results of most any type of application.
Make sure you read all reviews, from previous customers, to get a better understanding of the pros and cons of a particular machine. This type of information also helps you to make an informed decision.
