Description

A hydraulic press is a machine tool that uses a hydraulic cylinder to generate a compressive force. They are often used in shops to press interference fit parts together, such as gears onto shafts or bearings into housings. Some of the other uses include bending and forming metal. Some presses use a manual pump to produce the force while others use compressed air or a power unit driven by an electric motor.

Here is an example of this piece of equipment being used.

Documentation

Terminology

• Pressure Gauge- An indicator that uses a needle to indicate the amount of force being applied to the work piece.
• Release Valve Handle- This is the control handle for releasing the hydraulic pressure in the system. Turn the handle clockwise prior to charging the hydraulic system and counter-clockwise when releasing pressure.
• Table Holding Pin- 4 removable pins support the table and allow for height adjustment.
• Ram- This is is the end of the hydraulic cylinder rod that moves and pushes against your work piece.
• Pump Handle Socket- This is the location for handle placement while pumping up the hydraulic system.

General Procedure

Safety

When operating a hydraulic press be aware that extremely dangerous forces are produced which can cause parts to shatter and fly like bullets. It's very important to keep an eye on the force gauge while increasing force and to be aware of the dangers of flying parts. Always keep you hands away from the ram and parts being pressed. Keep stacked parts as short as possible to prevent tilting or buckling. If you have questions make sure to ask a supervisor prior to attempting something that could be potentially dangerous. Be aware that you may be working with heavy material located several feet above the floor and there is potential to drop metal on your feet.
