Hydraulic press is enlisted as widely used machinery in various industrial sectors, and the model is a machine press using a hydraulic cylinder that generates great and sudden compressive forces. The design of hydraulic press is based on Pascal's principle, that is, the pressure throughout a closed system shall be constant as always.
In a press machine, one part of the system is a piston which acts as a pump, with a moderate mechanical force acting on a small cross-sectional area. Besides, the other part of this machine is a piston with a larger area which generates a comparatively relevant large mechanical force. The C frame hydraulic press is a press machine based on the same mechanical principle that is designed with the appearance of a bowed shape that looks like the letter C, and is usually operated vertically.
In the modern days, hydraulic presses are commonly used in the metalworking sectors for many kinds of forming operations, such as clinching, forging, molding, punching, blanking, deep drawing, and other metal forming operations onto a wide variety of metal materials. With the press machines, the cycle time of the production procedure could be shortened in a large scale, and at the mean time, within an acceptable tolerance values regarding the output. Because compared with metal cutting processing, the procedure of metal forming offers faster shaping process that makes mass production feasible and able to be further developed.
Most of the press machines are used for mass production model, rendering work pieces in a targeted shape within a short period of time with a large amount of items. While currently, the trend of small amount but largely diversified production takes the leading role in the world industry, so that the issue of a quicker die changes mechanism in order to achieve agile manufacturing becomes very important.
Since all kinds of manufacturers may use the same model, so that in the global market it is important and critical for manufacturers across all kinds of industries in the global market to be in touch with the same specification with little custom changes. Business owners in the automotive and electrical sectors are those who adapt to this trend well among many other sectors because of the assistance of computer assistance such as CNC controller rather than the manual designs that only benefit the experienced operators but not all workers.
Here we give an instance, the production line of wheel rims requires complicated pressing processes due to the design of automobile wheels. Just for producing one type of rim, it takes a long production line to complete. However, manufacturers are faced with the demands to produce various rim products within the demanded period of cycle time.
So they come up with the automation system that can accelerate the operation of the hydraulic pressing manufacturing in the manufacturing sites. As a result, the correlation between forming machines and automation systems are getting more and more intimate nowadays. On the other hand, servo presses and mechanical presses are also widely applied as well as the hydraulic presses and each of them represents different mechanical advantages that are advanced than the existing solutions. Besides the metal working industry, with the ongoing development towards light-weight parts for sports, aerospace, and automotive appliances and many other industries, servo hydraulic and hydraulic presses have become a crucial tool for the thermoplastic industries in the plastics and rubber sectors.
Another application of the hydraulic technology in the press manufacturing is the high speed press machine. It is one of the most commonly adopted press machines in the modern industry. It is utilized by many manufacturers in the production of a variety of industrial items as well as products used in our daily basis. Regarding the industrial applications, many of them are applied to the manufacture of furniture, sport facilities, consumer electronics, automotive accessories and parts, and household appliances.
The size scales of the pressing die determines the corresponding sizes of the press machines to be selected and used. To be precise, both mechanical and hydraulic presses have been classified into several categories based on their operation, frame structure, and so on, such as hydraulic deep drawing press, hydraulic try out press, C frame press, H frame high speed press, just to name a few. If compared with other press machines such as try out press and ordinary production press, the physical force of hydraulic press machine would be much stronger because the primary task of this kind of machines is to make pressing on the work pieces no matter what its material essences is. However on the other hand, modern design of the press machines focus on another crucial element that is considered humane nowadays: the protective mechanism. Due to the high speed nature and great force, there were many dangerous possibilities and cases happened in the past and that kind of events happen even for now.
