The hydraulic press uses the principle of Pascal’s law. It utilizes the power of fluids for the operation. Usually, there will be three important parts in a hydraulic press; the machine, power source, and hydraulic control unit. Most of the hydraulic presses use one or more oil pumps as a power mechanism. The machine uses gear pumps for low-pressure applications up to 2.5mp, blade pumps for medium pressure applications up to 6.3mp, and plunger pump for high-pressure applications up to 32mp. Hydraulic presses reduce the production cost and will improve the strength and rigidity. The article uses of the hydraulic press will provide more details related to this topic.
Hydraulic presses have numerous applications in our daily life like blanking, deep drawing, straightening, punching, bending, forming and molding. It is impossible for a specific hydraulic press to perform all these applications accurately. So, to achieve all these functions, we have separate hydraulic presses to do these tasks. Some of those hydraulic presses are discussed here.
Four-Column Hydraulic Press
Four-column hydraulic presses are used for precision tooling applications. Four-column four-beam hydraulic press, four-column three-beam hydraulic press, and four-column two-beam hydraulic press are the different categories available recently. These presses are highly recommended for applications where pressure is a major consideration. The four-column presses will provide equal pressure distribution. Flexibility, versatility, smooth transitions, ease of operation, fast setup and maintenance, low-cost, etc… are some advantages of the four-column hydraulic press.
Single Column Hydraulic Press
Single column hydraulic presses are also known as C-frame hydraulic press. Because the body of this press is in C-type single-arm structure. Excellent rigidity, guide performance, speed, and high precision are the advantages of single-column hydraulic presses. Automotive, electronics, household and medical industries utilize the C-frame hydraulic presses for applications like sheet metal forming, plastic forming, bending, deep drawing, etc. The C-frame presses are convenient for small and mid-sized facilities because of its less floor space consumption.
Horizontal Hydraulic Press
Rail straightening and contouring, plate straightening, punching, structural straightening and contouring, punching, etc.. are some important applications of the horizontal hydraulic press. This is a multi-purpose machine and its parts can be assembled, disassembled, straightened, compressed, punched, etc. A standard horizontal hydraulic press will consist of a unique hydraulic system to protect the machine from overload. Different tools can be attached with this press. Heavy cast iron body of this hydraulic press provides maximum life span. Height of the working table can be arranged depending on workers comfort.
Two Pillar Hydraulic Press
Two pillar hydraulic press can be divided into oil press and water press based on the type of fluid used for transferring power. The water-based two pillars hydraulic press is commonly used for forging and stamping application. Durability, ease of maintenance and operation, etc.. are key features of this press. Also, these presses can be customized according to workers requirements by integrating other equipment.
