The availability of full machine force at any point in the stroke is very useful in deep drawing applications. Different tool heights or varying thicknesses of material have no effect on the proper application of force. When changing dies, different shut heights do not require fine shut height adjustment. The desired pre-set hydraulic pressure provides a fixed working force. Limiting the actual stroke will permit faster cycling rates and also reduce energy consumption. Only enough stroke length to provide part clearance is required. Another advantage is that the stroke may be adjusted by the user to match the requirements of the job. The full force of a simple hydraulic press can be delivered at any point in the stroke. The rated capacity of a mechanical press is available only at the bottom of the stroke. Hydraulic Presses Have Full Force through the StrokeДЇigure 2. Some mechanical presses do not develop enough force high enough in the downward stroke to permit severe drawing and forming applications such as inverted draw dies to be used without danger of press damage. Deep drawing and forming applications often require large forces very high in the press stroke. This feature is a very important characteristic of most hydraulic presses. The full force of a hydraulic press can be delivered at any point in the stroke. Figure 2 illustrates why the rated force capacity of a mechanical press is available only near the bottom of the stroke. Unique Features of Hydraulic Presses In most hydraulic presses, full force is available throughout the stroke.

A pressure regulator is either manually or automatically adjusted to apply the desired amount of force. The control system has electrically-actuated valves which respond to commands to advance and retract the slide or ram. The motor drives a rotary pump, which draws oil out of the reservoir housed in the machine frame. Additional alignment is provided by two round guiderods. The ram is actuated by a large hydraulic cylinder in the center of the upper part of the frame. The bolster and ram provide a surface to mount tooling. The frame is of robust construction to limit both angular and total deflection. The press shown in Figure 1 has a frame and bolster that are similar to the construction used for open back stationary (OBS) mechanical presses. A typical hydraulic press featuring gap-frame construction.

Figure 1 illustrates a gap-frame or C-frame hydraulic press.ДЇigure 1. The style of the press frame and the hydraulic components vary depending on the intended use. Lown for subsequent public presentations.Д®xample of a Gap-Frame Hydraulic Press Like the mechanical press, hydraulic presses deliver a controlled force to accomplish work. Lown, 'Hydraulic Presses in the 80's', Based on SME Technical Paper, MF82-918, The Society of Manufacturing Engineers, Dearborn Michigan, В© 1982. Hydraulic presses with double actions and or hydraulic die cushions are capable of forming and drawing operations that would not be possible in a mechanical press. Forming and drawing speeds can be accurately controlled throughout the stroke. There is no tonnage curve derating factor. Die shut heights variations do not change the force applied. Single stroking does not result in additional press wear. In small lot production where hand feeding and single stroking occurs, production rates equal to mechanical presses are achieved. Depending on the application, a hydraulic press may cost less than an equivalent mechanical press. New fast acting valves, electrical components, and more efficient hydraulic circuits have enhanced the performance capability of hydraulic presses.ДЇactors That May Favor the Use of a Hydraulic Press Factors that may favor the use of hydraulic presses over their mechanical counterparts may include the following: 1.

Widespread application of other types of hydraulic power equipment in manufacturing requires maintenance technicians who know how to service hydraulic components. Modern hydraulic presses offer good performance and reliability. The training of tool and die makers and manufacturing engineers in North America has been oriented toward applying mechanical presses to sheet-metal pressworking. 1ДЄdvantages of Hydraulic Presses The mechanical press has been the first choice of many press users for years. Modern hydraulic presses are, in some cases, better suited to applications where the mechanical press has been traditionally more popular. In its modern form, is well adapted to presswork ranging from coining jewelry to forging aircraft parts. HYDRAULIC PRESSES The hydraulic press is one of the oldest of the basic machine tools.
