How to Mechanically Stretch Steel Pipe With a Hydraulic Press

Utilizing a hydraulic press for shaping, forming, and bending metal has many advantages over mechanical presses in terms of cost efficiency and ease of maintenance requirements.

Hydraulic presses feature fewer moving parts that are fully lubricated with pressurized oil, leading to less breakdowns and downtime.

Stretching

Hydraulic presses are pieces of machinery that use water or oil pressure to generate pressure, making these machines ideal for creating large contoured parts by pressing, bending and stretching metal sheets. They come in handy for various tasks ranging from making metal bend to pressing out metal sheets for precision parts production.

Bending stainless steel tubing can be an intricate and time-consuming process that involves significant direct pressure. Acquiring precise bend radiuses may prove challenging; as well, this may take quite some time before completion of the bend process.

One way to solve these problems is with a hydraulic tubing bender, which you can purchase both online and at hardware stores. While they can be expensive, you could always create your own hydraulic system on a budget using welding lengths of pipe together into frames for the plunger before connecting this frame with a one-way valve and main hydraulic press head.

Bending

Rolling is a good way to form gentle curves on stainless steel tubing, while bending is better suited for creating sharper bends. Bending requires using a metal piece called a mandrel in order to avoid internal diameter loss while shaping.

An hydraulic press can bend steel pipe without deforming its external surface, but when purchasing one for this task there are certain considerations that need to be made when purchasing such an apparatus. Consideration must be given to factors such as frame construction, bolster thickness and maximum system pressure generated when at full tonnage.

Also important to keep in mind when purchasing a hydraulic press is its built-in overload protection feature. If the machine is designed to exert 200 tons of pressure and you accidentally press down on the tool, its safety valve will open to release any excess force accumulated during use. This makes them more durable and less prone to human error damage; they also feature very few moving parts which contributes to low noise levels that meet or surpass industry standards.

Pressing

Hydraulic presses come in various varieties to meet a range of tasks. Your choice will depend on the desired tonnage; some machines even perform multiple functions and reduce machinery requirements.

Hydraulic presses can also help straighten shafts or sheet metal that has become bent or deformed by relieving stress caused by their bend, helping restore their original form.

Presses like these are also utilized in laboratory settings to compress powder mixtures into pellets that can be examined using X-ray fluorescence spectroscopy for quality assurance purposes. This helps manufacturers ensure the quality of their products.

Hydraulic presses use hydraulic cylinders - single-direction mechanic actuators that convert fluid power into mechanical pressure - in order to compress materials more effectively than traditional mechanical presses, which often require three times as much power.

Safety

Hydraulic presses are heavyweight machines with moving components that must be maintained and properly lubricated to ensure safety, reliability and efficiency for machine shops and their operators.

These tools are widely utilized for various metal-forming jobs, including deep draws, shell reductions, urethane bulging, straightening, bending, stamping, forming, blanking piercing staking and punching. Furthermore, these machines can also be utilized for powdered metal forming bearing compression track and tire production press fitting and more.

One of the key advantages of hydraulic presses is their increased versatility over their pneumatic counterparts. While pneumatic actuators rely on air, hydraulic presses use compressed oils that don't delay movement and deliver much higher pounds-per-square-inch (psi) capacity compared to pneumatic machines. As a result, hydraulic presses can more effectively handle heavy-duty tasks than pneumatic machines can; their ease of use makes them incredibly popular among manufacturers of steel tubes, steel pipe fittings and x-ray fluorescence (XRF) sample preparation equipment manufacturers alike.
