The manually operated oil-hydraulic laboratory press makes Press fundamental feature is the easy and quickie interchange and adjusting of punches and dies.

The EP is a manual toggle press with a round ram. The press exert the rated force at the end of the stroke at the bottom dead center. Through this procedure, the high pressure This manually-operated toggle press is equipped with round ram, and has a force capacity of up to 7,5 kN. It is suitable for applications where large installation area is In addition, it comes in different types, such as manual , pneumatic and hydro-pneumatic presses.

These presses enable the realization of several assemblies, camberings, and fixings. The series includes two types of press. They are suited for a range of applications. The rack bench presses enable carrying Model Mini C Twelve ton manual , two-column hydraulic press with 6" x 6" square platens. Compact and portable, requiring less bench space than our Model C.

This press is ideal for constricted The portable piercing units of the ULBG series are characterized by their high pressing force of 60 kN combined with a very lightweight handling. The ergonomic handle guide of this drive unit completes its appearance Due Available with manual , pneumatic or hydropneumatic control in a range of sizes suitable for riveting, trimming, drawing, keying, sizing, straightening, bending, die-cutting.

Rack and Pinion Presses ZF. Pneumatic Presses PF. Pneumatic Presses with manual aproach. From idea conception through prototype, beta build and production, KTC is ready to take on your product development requirements. Industrial presses apply a controlled force to a material or part to complete a process step. They can be powered by many different energy sources and range greatly in size.

Many manufacturing facilities use an industrial pressing operation in their process to create, form or assemble a product. Entire books are written on the topic of industrial presses, so this article will narrow its focus and concentrate on the relatively low-force, precision press machines used to assemble component parts. Most assembly presses are made up of a frame, ram and platen. Each type of press creates force in a different manner and this impacts the application, purchase price, operational cost, precision, safety, and process feedback capabilities.

As the name implies, these industrial press machines are powered by a human operator. They are simple, basic tools and therefore the purchase price and operational cost of this type of press is low. Manual presses utilize different methods to produce force and linear motion of the ram. A common press for very low-volume assembly work utilizes a self-contained hydraulic system. Pumped via a lever, a hydraulic cylinder slowly extends with high force to press self-guided assemblies together.

This system is very slow and takes a lot of effort, so it is typically used only for one-off, high-force processes. Arbor presses utilize a lever arm or large wheel with a mechanical linkage to move the press ram up and down. The force is amplified by the linkage, which is typically either a rack and pinion or toggle mechanism. Rack and pinion presses amplify the applied force equally throughout the entire ram stroke. Toggle mechanisms start out with a lower force and increase the amplification toward the end of the stroke.

In all of these variants, the assembly process and speed is controlled entirely by the operator. Press monitoring options are limited but include stroke verification switches, force displays and also locking mechanisms, which prevent the ram from being raised unless the stroke has been fully completed.

Like any hand tool, safe operation of the press is the responsibility of the operator. These assembly processing machines utilize compressed air as their power source. The maximum force is relatively low and is determined by the cylinder bore size and the pressure of the regulated air source. The press force is consistent throughout the entire ram stroke and cannot be adjusted mid-stroke by the operator. Advantages of the pneumatic press type are its higher speed, relatively low total cost and reduced operator fatigue.

With additional control devices and cost, the assembly process can be monitored using stroke position switches, linear transducers, load cells, and part sensing devices. Since air is compressible, unless an additional oil-dampening circuit is employed, the working press stroke may be choppy and vary from part to part.

A machine safety assessment , by qualified professionals, is extremely important and should not be overlooked. Not only is compressed air stored energy, if the air source fails, the press ram could fall, which could also cause injury.

To prevent a falling load, air-piloted check valves or shaft-locking devices may also be necessary. These machines are similar to pneumatic presses and many of the characteristics, advantages, disadvantages, and safety concerns mentioned above hold true. They are powered by compressed air; however, the addition of hydraulic oil into the control circuit enhances the capabilities of this press type.

Since oil is not compressible, it can be safely intensified to high pressures. The high-pressure oil is smaller in volume than the air that produced it, so the total displacement of the high force stroke is relatively short.

These presses can consume a lot of compressed air, which is a costly form of energy; however, they can be a good, lower-cost solution in many applications. This type of industrial machine utilizes plant electricity, a hydraulic power unit and a hydraulic cylinder to move the press ram. They are ready for use as soon as part-specific tooling is mounted to the ram and platen.

Ram speed is limited by the flow and oil volume restrictions of the hydraulic power package and circuit. Thanks to its design office and a fleet of more than 40 machining machines, EMG studies and realizes on request any modification or realization of special presses as well as small press layouts and tools, such as : - Offset toggle press allowing to increase the depth of the gooseneck and the work table.

Manual presses can be used for the assembly of many types of products whether they are rack and pinion or toggle presses. They are adapted to small series production for small to medium size parts. Although less adapted to bending than pneumatic presses or mechanical presses, manual presses can be very efficient to bend different materials.

It is important to check the characteristics of the manual press, including the pressing force allowed by the press, to ensure that the desired result is achieved. Whatever the intended operation, the operator manipulates the lever or the handwheel to exert the necessary pressure throughout the stroke or at the end of the stroke for toggle presses.
