The automation program designed for press machines was common now and was also common even in the past. Press automation is the mechanical engineering that can connect the pressing steps altogether into one integrated automation system, making the press forming well integrated without too much needs of manual operations.
Without automation, forming presses are conventional metal forming machines that use stamping or pressing methods to achieve the forming goals on work piece components. Forming press machines were widely used in the metal working industry to do a lot of forming works such as utensil production, wheel manufacture, forging process, and other metal forming processes. Now, as the automation technology has pull out the inconvenient issues, more and more press machine suppliers add the automation elements into their production lines.
One of the most famous and old fashioned forming press models is the C frame forming press. This is widely used traditional forming machinery in various industrial sectors. Most C frame press machines are of hydraulic power source, and the hydraulic forming presses are machine presses using hydraulic cylinder that generates great and sudden compressive forces on the targeted components and materials with controlled stamping action. So once if it is going to be automated, the press automation shall be connected also to the hydraulic controlling units. Stamping action is another specific metal forming subject that will be discussed as this is another form of press automation. Materials and the material features for the C frame presses are the two things that need to be taken into consideration when people are designing press automation.
The development of C frame forming press is designed based on the well known genius Pascal's principle. Blaise Pascal is a mathematician who did a lot of researches that aim to deal with all kinds of problems and his achievements are also applied to the forming press mechanics. The pressure throughout a closed system in the C frame machine shall be constant as always is the main notion of the stamping loop mechanism. In a forming press machine, one part of the system is a piston which acts as a pump unit, and the unit is with moderate mechanical force acting on a small materials cross-sectional area. Besides, the other part of this machine is a piston with a larger area which generates comparatively relevant large mechanical stamping forces calculated for the processing work pieces. The C frame hydraulic presses are forming presses designed based on the same mechanical principle that is designed with the appearance of a bowed shape that looks like the English letter C, and is often operated vertically together with the tables designed for work pieces. Metal forming is an art as well as a rigid metal forming science.
Automated hydraulic forming presses are commonly used in the metalworking sectors for many kinds of forming operations, such as clinching, forging, molding, punching, blanking, deep drawing, and many other metal forming operations.
With the automated press machines, the cycle time of the production procedure could be shortened in a large scale together with the tooling advancement as these are all calculated and integrated into one. At the same time, within an acceptable tolerance values regarding the output, the tooling enhancement is the key to improved processes and stamping mechanisms. Compared with metal cutting processing, the procedure of metal forming provides faster shaping processes that makes massive production model feasible and practical. Some top notch scientific studies such as the ITER fusion machine involves a series of production and assembly processes, and the well organization of those works is just like the coordination of the metal forming process with good stamping arrangement.
Under such premises, press automation is the goal to achieve unmanned pressing working shifts that can work by simple settings that are once done by onsite engineers and the following processes will be achieved by the coordination of all the automated pressing equipment around the production line circumstances. The automation technology of forming is slightly different form the automation model used in metal cutting industry, but the overall pattern that involves the coordination of supportive equipment such as feeding, handling, processing, machining, etc. are basically the same.
