A power press machine (power press) is used to perform punching, shaping, etc. using the mold. The movement of power presses is reciprocating and perpendicular to the bed of the machine table, the pressure of which is supplied both mechanically and hydraulically. Although the power generated by the hydraulic system and the mechanical system is not much different from each other, the use of power mechanical press has become more widely used in industry. One of the main reasons for using a mechanical power press is the number of times it hits.
In the mechanical version, the ROM is connected to the crankshaft and then to the flywheel and is always rotating when the electric motor is running. The connection between the crankshaft and the flywheel is done by the clutch. In this system, clutches are divided into two categories:
When disconnecting in all rotation clutches (full rotation), it will not stop until the ROM completes its reciprocating motion. Also, the crankshaft will definitely complete one turn. These clutches have a dangerous movement cycle due to their age.
When disconnecting in these clutches, the machine stops moving before the Ram reciprocating movement is completed. In other words, the crankshaft will not rotate completely and can be detached from the flywheel anywhere at work. Most semi-rotating clutches use air and a braking system. When air accumulates in the clutch compartment, the clutch engages and the brake is released. This process happens to stop the photo press.
Types of power press machines and their applications
Due to the user they have and the expectation of providing strength and continuity in their performance power-duty presses are divided into two categories: C-Type and H-Type.
C-type power press
Stability in performance
Easy to use
Low power consumption
Uniform performance quality
H-Type power press
Stability in performance
Requires low maintenance
Has lubrication system (manual / automatic)
Hand protection immune system
This type of power press is used to produce repetitive parts and low carbon steel is used to produce various parts including flats, plates, reinforcements, and cutters. The C-Type power press uses a knock-out mechanism to eject the workpiece. These presses are also called power column presses and due to their high-pressure tolerance, they are widely used in the machine-building and parts production industry.
Power column presses use an integrated steel body, which increases the accuracy and durability of the machine during production. The clutches used in it are designed for mass production and their crankshaft is usually made of alloy steel, which is combined with metal bushings for soft operation and a long time.
Advantages of C-Type Power Press:
H-type power presses have a rolled steel body made of IS-2062. The steel frames used in them are connected to each other after de-stressing, which will cause high performance. In addition, the welds used on the body and structure of the machine are free of any strain and stress, and this allows the accuracy of the machine not to be disturbed during operation.
H-Type press is used to supply static hydraulic pressure for pressing various metals, including steel and other materials. This machine is used to make steel and iron parts in the machine-building and other metal industries. .
Advantages of H-Type Power Press:
Advantages of power press machines:
Different designs and applications of these machines allow users to easily work with them.
They are used for trimming, straightening, assembling, and cutting different shapes.
Power presses are known as stable, strong, and low energy consumption press.
They do not need much maintenance.
If the dimensions of the small power press are selected, its stable operation for a long time will be guaranteed.
Buying a power press machine:
Despite the simple appearance and function of press machines, the process of buying them has many important points that must be considered. The question is what kind of power press machine is suitable and how to prepare it?
The answer to this question has several parts that can be helpful to pay attention to:
Type of production:
Technical specifications of the sheet:
Technical specifications of the machine:
How to place the sheet and move it (automatic, robotic)
The machine consists of an integrated configuration or its welding joint is de-stressed.
Select the dimensions of the machine according to the dimensions of the work environment, sheets, and the power of the machine.
Check the sound produced by the machine.
The bed of the machine has good endurance so that in addition to withstanding the impacts, it can also withstand the kneading of parts.
If necessary, the machine can be ordered with a flying system.
If you choose a very large machine, its bed can be made a little below ground level so that in addition to better endurance, it also has easier access.
Consider the minimum and maximum course length of the machine for each round trip.
Consider the dimensions of the Daylight machine aperture with or without mold.
Check the tonnage of the machine. The choice of machine tonnage is directly related to the technical specifications of the sheet.
Check the number of courses per minute. Because it determines the speed and circulation of production.
Consider the power of the machine's electric motor in KW.
Check the brand of electric motor and used parts as much as possible.
Order the required accessories along with the machine, if necessary.
Business and shopping tips:
Specify what type of product is produced? Consider the shape, material, technical specifications of the sheet, and the production run. It should also be noted whether there is a possibility of product change and subsequent molds or not.
Manufacturers and industry owners consider an efficient, robust machine, without the need for maintenance and the ability to produce in long working hours. But can all these expectations be summed up in one machine? The answer is no. Because not all such features can be considered 100% in one power press machine. Therefore, it is necessary to refer to the question that is closer to the demands and expectations in production.
To know this machine, you should start by examining the information of the machine provided by its manufacturer, and then reach the desired result by comparing different presses.
In order to find out what machine is capable of producing the desired products, we must examine the technical specifications of the sheets that we want to produce in the future. Sheet material, thickness, sheet dimensions, sheet type, sheet sleep and the desired process (punch, form, etc.) are some of the items that should be considered.
If the type of production, the level of expectation from the production, and the technical specifications of the sheets are examined, the selection of the machine will be done with better ease and peace of mind. At this stage, you can visit FactorNeed.com to examine the types of power press machines and see their technical specifications.
When examining the power press, pay attention to the following points:
After reviewing the technical points of the machine and comparing the machines with each other, the choice becomes easier and the purchase can be done with better confidence. In this case, after selecting the machine, its commercial points are considered. Careful observance and implementation of business principles (selection, purchase, order registration, transportation, currency allocation, clearance, and delivery of goods) should be done by an experienced team to reduce the potential risks and injuries.
