Types of pressing machines and ways to select the best from the batch
The pressing is primarily a specific form of a machine tool. This is necessary for the development of many industrial production methods. This machine tool helps to supply energy with a force that can control in a single stroke or at a distance. An important application is the industry of metal forging units. Energy is used to close the die and forge the inside. These machine tools used to work with force. And energy in a different way than drop hammers. Hammers also part of the machine tool, but they are of a very different type. Forging is the only form of manufacturing process that the press uses. Hydraulic Power Press
More about the main engine:
Pressing machines are often used in sheet metal production and metal extrusion processes and are described as the most important machine tools. Mechanical and hydraulic presses added mainly in sheet metal production. The presses are designed for the production of a wide range of plastic parts. In addition, some processing operations may require the use of presses, such as drawing.
Difference in size and strength:
These pressure devices are designed to vary the amount of force applied and the range. The energy produced is often used to process processes that require a lot of energy. Some examples large plastic deformation work on large metal parts. Depending on the type of machine used, there are differences in the nature and method of energy supply.
Available vertical presses:
You can see vertical presses as a type of machine. Here the vector of force up and down is somewhat related to gravity. In some cases, these types are used horizontally. Here, the force is given in a straight line in the direction of gravity. Whether the force is applied horizontally, vertically or at half an angle, the working principles are the same.
There are two types:
In general, pressing machines come in two main types; mechanical presses and hydraulic presses. The type of printing machine will differ depending on the production method. The first consideration should be the basic process of such a pressing tool. For example, a tool used for extrusion has different general requirements compared to a tool used for extrusion of a worksheet. Another thing to consider is the required press capacity. The required capacity is related to the size of the work equipment and the type of process.
Other important factors to consider:
The length of stroke at which the press will deliver power is another factor to consider when selecting a machine. This should be related to the base type process being used. By going through these initial considerations, you will get a general idea of the types of presses that are available and needed for your job. The specific factors of such a manufacturing method should consider when determining the best press tool. In addition to hydraulic. And mechanical presses. You may want to consider checking the operation of crank presses. Go through the detailed functionality first before you plan to invest money in one.
HOW PRINTING EFFECTS WORK
Once the ton of demand is resolved, it’s time to find out the impact of the stroke on work. Is it the same as a mechanical press? Again, the answer is yes in most cases. There are certain specific limitations. For example, hammers fall and some mechanical pressures seem to work better on soft jewelry and impact tracks. The action of the coin seems to be sharper when the effect is present.
However, during deep drawing, the full force stroke of the hydraulic press can provide better results. Otherwise, there are very few cases where the use of 100 tonnes of hydraulic power creates a significant difference in the nature of the part supplied by the same equipment.
Cutting tools can reduce the pressing tonnage of hydraulic presses in the same way as mechanical presses.
WHICH TYPE OF PRESSing IS BEST FOR APPLICATION
Now is the time to find out which type of hydraulic press is best for your particular application. Open hole presses allow easy access from three sides. The four-column pressure ensures proportional pressure distribution. Straight edge presses provide the rigidity needed for eccentric loading in progressive die applications. One important thing to keep in mind is: The more critical the work and the more permits are required, the greater the spare tonne of capacity.
- Once the criteria are set, the next thing to consider is the options. Most hydraulic press manufacturers offer a wide range of accessories, which often include:
- Limit switch for distance reversal
- Hydraulic pressure switch back
- Automatic (continuous) cycling
- Delay timers
- Sliding supports and rotary index tables
- Pillows
- Ejector rollers or punches
- Electronic light curtains and other appliances
- Touch screen control
- Servo system feedback for accurate, consistent, repetitive stroke controlNext, you need to know what quality you need to do the job. The quality of a press can vary considerably from press to press. There are lightweight presses that can “beat” a job and turn for a moment, and there are heavy-duty machines designed for general purpose metalworking applications. Some design points can be used to compare one machine with another:Frame: Check frame structure strength, cradle thickness, dimensional capacity, and other factors.
- Cylinder: What diameter is it? How is it constructed? Who makes it? How serviceable is it? ? Maximum system pressure: At what dog does the press develop a full ton? The most common range for industrial pressures is 1000 psi to 3000 psi.
- Power: The duration, length and speed of the pressure stroke determine the required power. Compare performance ratings.
- Speed: Determine the speed of each supplied hydraulic press.
Be careful buyers
There are many potential pitfalls to consider when choosing a hydraulic press. Specific items to look for include:
- Speed. No hydraulic press today is as fast as the fastest mechanical press. If speed is the only requirement, the application cure and the material stroke is relatively short. A mechanical press remains the best choice.
- Stroke depth. If a limit switch uses to determine the bottom. It is unlikely that the stroke depth will control much closer to 0.020 inches. Multiple hydraulic presses can set to rotate at a preselected pressure, often leading to identical parts. Often, when perfect stroke depth accuracy require.
- Automatic feeding equipment. Hydraulic presses require some external or auxiliary energy to feed the material. The feeder must have its own power supply. And must integrate into the press control system. However, there is a growing selection of self-propelled feeding systems, such as rolling, hanging and air.
- Shock after a breakthrough in blanking. Mechanical and hydraulic presses have this problem. However, the hydraulic system of the hydraulic press must also isolate from the shocks associated with decompression. If the hydraulic system does not have an anti-shock function. This shock will affect the lines and equipment.
