How To Properly Inspect a Hydraulic Press

Used thousand ton stamping pressWe have all been there. Whether looking through print classifieds or online postings, we finally come across that specific piece of machinery that is so desperately needed. As we review the product information, it comes to us

Is this deal to good to be true?

When it comes to making a final decision and determining how useful a discovery is, we must inspect the equipment before purchasing it. This is no different when searching for a functional hydraulic press.

Without question, in order to maintain a high level of hydraulic press productivity, it’s essential to follow a detailed preventative-maintenance (PM) program that has already been created by the machine’s manufacturer.

Hydraulic Press Inspection Steps

Of course, the first step in the process is to find out if the current owner has taken proper care of the machine. You will want to check the cleanliness of the equipment while also inspecting the general appearance of the hydraulic press.

In some cases, you will be able to determine whether the press is a good find just by how it looks. But, don’t rely on exterior appearances alone.

By fully understanding the machine’s operational capabilities, anyone searching for a hydraulic press will be able to determine if the machine is in good condition or not.

This is not only true for this specific piece of equipment, but for other machines too.

The Feed Actuators

Quite possibly the most important component of a hydraulic press is the feed actuators.? The physical condition of the feed actuators will be able to determine the exact position of the machine tool and make sure that it adjusts to the proper position in relation to the punch above it.

By ensuring that the feed actuators are functioning effectively, you will be able to determine if the component will stay in place until the metalwork has been completed.

The Pressure Intensifier

In order for the machine to work properly, this component will be completely powered by an air pressurizer that manages the manifold pressure that is controlled by specific valve outputs.

Without a proper functioning pressure intensifier, a hydraulic press is virtually useless.

The Controller

When inspecting the machinery, the controller is the next most important operational component to be found

The controller is a specific computer program that allows the press operator to input certain commands. Whether you need to perform an individual task or a variety of them, the controller is the main part that will allow this to happen.

Inspecting a Machine Tool Online

If you need to inspect used equipment that is being sold online, it can be extremely hard to find the results that you require. In order to receive the proper inspection on a potential hydraulic press online, you will need to use all of the resources available to you.

A good idea would be to ask the seller for a live video of the machine in operation or to take advantage of live video chat software.

Bearing Presses Anyone?

norco bearing pressA bearing is a tiny round cartridge that is made of steel and houses a ball bearing. A bearing press tool is used for leverage to make wheel maintenance quicker and less challenging. Basically, a bearing press aids in the installation of bearings without causing any damage to the shields.

Creating a homemade wheel bearing press is not difficult, and it will save you frustration and potential bearing damage, and all you will need is a threaded rod, a couple of washers and nuts that fit onto the threaded rod.

A wheel bearing press replacement kit may be a great investment for many people, as it allows the operator to change the bearing without affecting the alignment of the wheel. A full kit is usually priced at under $200, and has everything required, to confidently confront a variety of wheel repairs needed, with ease, expertise and stealth.

Different Types

On the other hand, a hydraulic bearing press is considered to be a large mechanical piece of equipment that is used to raise and compress large items. Also known as a Bramah Press (named after its inventor, Joseph Bramah).

During the selection process of pre-purchasing a hydraulic bearing press, the generated force is an important factor to consider. The forced pressure depends on the piston size and the distance it needs to travel. To find out how far a large size piston will move, simply divide the piston head ratio by the distance that a small piston moves.

What Industries Use Them?

Goldsmiths have used hydraulic bearing presses for generations, and it is not uncommon to find a 160 ton wheel bearing press in the jewelry industry today. A 15 ton bearing press is used for minor blanking and other small jobs.

The press operator is mainly responsible for properly placing and feeding the stock into the machine, activating the machine, and then removing the completed material from the machine.

There are physical hazards associated with working with any type of press, especially a hydraulic bearing press or manual wheel bearing press.

Besides tripping and electrical-type hazards, there is also the potential for chemical hazard from the hydraulic fluid, and other type of lubricants, if these chemicals come in contact with human skin.

Due to the fact that bearing presses, especially hydraulic bearing presses, operate with 20 plus tons of pressure, there is the risk that a sharp part may give in and fly from the press with lighting speed, and cause damage to the machine, and more importantly to any humans nearby.
