What are the different types of oil press press?

In the metal processing and manufacturing industry, oil press presses have become the core equipment for stamping, forming, shearing and other processes due to their high precision, high efficiency and stable pressure output. The types and functional differences of oil press presses directly affect processing quality and production efficiency, from automotive parts production to electronic component manufacturing. This article will systematically analyze the classification system, technical characteristics, and applicable scenarios of hydraulic punching machines, providing selection references for industry users.

1. Classified by structural form

1. Open oil press press
Features: The body has a "C" - shaped opening, providing ample operating space and facilitating mold replacement and workpiece placement.
Applicable scenarios: Small and medium-sized batch production, frequent switching of multiple varieties, such as stamping of household electrical casings and forming of hardware components.
2. Closed oil press press
Features: The body has a closed frame structure, strong rigidity, excellent resistance to eccentric loads, and is suitable for high-precision and large tonnage processing.

Applicable scenarios: Precision stamping of automotive coverings, aerospace structural components, etc., such as stretching and forming of car door inner panels.

2. Classified by functional purpose

1. Universal oil press press
Features: Wide pressure range (50-3000 tons), adaptable to various molds, supporting basic processes such as punching, bending, and stretching.
Applicable scenarios: Multi industry universal processing, such as electronic connector stamping and building hardware forming.
2. Specialized oil press press
Features: Optimized design for specific processes, such as high-speed punching machines (with a punching rate of up to 1000 times/minute) and deep stretching punching machines (with a stretching ratio exceeding 2.5).

Applicable scenarios: Large scale standardized production, such as mobile phone frame stamping and tank deep drawing forming.

3. Classified by driving method

1. Pump direct drive type
Features: Directly providing pressure through a hydraulic pump, simple system, low cost, but with significant pressure fluctuations.
Applicable scenarios: Low precision, short stroke machining, such as punching simple parts.
2. Energy storage driven type
Features: Utilizing an accumulator to store high-pressure oil, achieving instant high-pressure release and increasing energy utilization by 40%.

Applicable scenarios: high explosive force demand scenarios, such as thick plate punching and precision correction.

4. Classified by degree of automation

1. Manual oil press press
Features: Manually operated slider movement, suitable for small-scale trial production or maintenance workshops.
2. Fully automatic hydraulic punching machine
Features: Integrated PLC control, mechanical arm for material handling, achieving 24-hour unmanned production.
Applicable scenarios: Large scale continuous production, such as the stamping line for car seat slide rails.
The selection of the type of oil press press requires comprehensive consideration of processing accuracy, production batch size, and cost budget. From the flexibility of open structures to the high rigidity of closed frames, from the multi scenario adaptation of general-purpose equipment to the efficient specialization of specialized punching machines, technological iteration is driving the industry towards upgrading towards intelligence and energy conservation. In the future, with the integration of digital twins and AI predictive maintenance technology, oil press presses will achieve optimal efficiency throughout their entire lifecycle, providing core driving force for the transformation and upgrading of the manufacturing industry.
