Advantages of Hydraulic Press Machine

Hydraulic press machines are more admired these days in industrial markets due to their efficiency, ease of operation, durability, longevity, suitability, flexibility, and low maintenance cost. Gone are the days of engineers searching for the best machining press among hydraulic, pneumatic and mechanical types. Due to the many positives of Hydraulic Press Machine, these are the most preferred machines in the present industrial sector.

Benefits of Hydraulic Press Machine

Full Power Stroke

The full power of the Hydraulic Press Machine can be delivered at any point of the stroke. Not only at the very bottom, as is the case with mechanical presses. Benefit? No allowance for reduced tonnage at the top of the stroke. For example, in drawing operations, you have the full power of the press available at the top of the stroke. You don't have to buy a 200 ton press to get 100 tons in full stroke. Other advantages are faster set-up and no time-consuming task of adjusting the stroke nut on the slide to accommodate different dies.

Built-In Overload Protection

A 100-ton hydraulic press will only apply 100 tons of pressure (or less, if you set it for less), no matter what set-up mistakes you make. You don't have to worry about overloading or the press breaking or dying. When a hydraulic press reaches its set pressure that is all pressure. The relief valve opens at that limit and there is no risk of overloading.

Very Low Original Cost and Operating Cost

Hydraulic Press Machine is relatively simple, and you may be surprised at the significant cost advantage over mechanical presses in comparable sizes. The number of moving parts is small, and they are fully lubricated under a flow of pressurized oil. Breakdowns, when they do occur, are usually minor; No, for example, like a broken crankshaft. Packing, replacement of solenoid coils and sometimes valves are typical maintenance items. Not only are these parts cheap, but they can also be easily replaced without breaking the machine. This means more up-time and lower maintenance costs.

Large Capacity at Low Cost

It is easier and less expensive to purchase certain types of capacity in a Hydraulic Press Machine. Stroke lengths of 12, 18 and 24 inches are ordinary. It is easier to provide additional stroke length. Open gap (daylight) can also be added at no additional cost. Similarly, small presses with large table area and large bed area can be provided. Large 200 ton presses are available with relatively small beds; the tonnage of the press does not determine the size of the bed.

Greater Control Flexibility

Hydraulic Press Machine power is always under control. Ram force, direction, speed, release of force, duration of pressure, all can be adjusted to fit a particular task. Light dye work can be done by reducing the pressure. Rams can be made to work fast, then move to slow speed before contacting work. Tool life is thus longer. Timers, feeders, heaters, coolers, and several of auxiliary functions can be sequenced to suit the job. Hydraulic presses can do much more than just move up and down, up and down.

Greater Versatility

A single hydraulic press can perform a variety of tasks within its tonnage range. Commonly seen are deep draw, shell reduction, urethane bulging, forming, blank and pierce, stake, punch, press fit, straightening and assembly. They are also wielded for motorized metal forming, abrasive wheel forming, gluing, broaching, ball sizing, plastic and rubber compression, and transfer molding.

Quieter

Fewer moving parts and the elimination of a flywheel diminish the overall noise level of hydraulic presses compared to mechanical presses. Properly sized and properly mounted pumping units meet and exceed current federal standards for noise even with the pump at full pressure.

Because each step of the ram movement can be controlled, the noise level can also be controlled. A hydraulic ram can be controlled to go through the work slowly and silently.

More Compact

A typical 20-ton hydraulic press measures eight feet high, six feet deep and two feet wide. A 200-ton press is only ten feet high, nine feet deep and three feet wide. At ten times the capacity, a 200-ton press takes up only 50 percent more floor space. Hydraulic presses tend to be less and less expensive than mechanical presses.

Lower Equipment Cost

Same goes for built-in overload protection device. If they are built to withstand a certain load, there is no risk of damage to them due to overloading. Tools may be sized to withstand the load of a particular job, not a particular press. The pressure of the press can be reduced to suit the job. The lack of impact, shock and vibration promote long tool life.

Safety

No Hydraulic Press Machine Manufacturer will (or should) claim that hydraulic presses are safer than mechanical presses. Both types of machines are designed and manufactured to be safe if the built-in control and safety features are used properly. All machines used incorrectly are potentially dangerous. But the control factor of ram movements makes it easy to secure the hydraulic press. Non-tie down, anti-repeat, dual palm button reins are used. The interlocking of guards as well as other safety devices is relatively easy due to the nature of the hydraulic press control system.
