Product Specifications

Technical details and manufacturing context for Primary Forming Press

Definition

The Primary Forming Press is a core component of the Integrated Metal Forming and Finishing Production System, responsible for the initial deformation of metal workpieces through compressive force. It transforms flat metal sheets or blanks into basic three-dimensional shapes that serve as precursors for subsequent finishing operations, establishing the fundamental geometry and structural integrity of the final metal product. This press is typically used in the fabricated metal product manufacturing industry, where it performs the first shaping step in a production line. The press operates by converting electrical energy into mechanical force through a hydraulic system or mechanical linkage. A ram or platen descends with controlled pressure onto a metal blank positioned over a die, forcing the material to conform to the die cavity shape. Pressure is maintained for a specified duration to ensure proper material flow and shape retention before the ram retracts. The press is available with a nominal force ranging from 1000 to 6000 kN, a stroke length of 200 to 800 mm, and a production rate of 10 to 60 strokes per minute. It accommodates a die height of 300 to 800 mm and a bolster area of 800×800 to 2000×2000 mm. Slide adjustment ranges from 50 to 200 mm, and positioning accuracy is ±0.05 to ±0.1 mm. The motor power is 15 to 90 kW, and the supply voltage is 380 to 480 V AC (three-phase, 50/60 Hz) per IEC 60038. The operating temperature range is 5 to 40 °C, and the protection class is IP54 to IP65 per IEC 60529. The machine weight is 10 to 80 t. Materials typically used for the press structure include high-strength alloy steel and tool steel. The nominal force parameter is referenced to ISO 16092. These values are directory reference ranges and must be confirmed for the actual model and application with the legal manufacturer or supplier.

Working Principle

The press operates by converting electrical energy into mechanical force through a hydraulic system or mechanical linkage. A ram or platen descends with controlled pressure onto a metal blank positioned over a die, forcing the material to conform to the die cavity shape. Pressure is maintained for a specified duration to ensure proper material flow and shape retention before the ram retracts. The process is controlled by parameters such as nominal force, stroke length, and strokes per minute, which are set according to the material and desired shape. The press is integrated into a production system, with interfaces for material handling and control signals. Verification of performance involves checking positioning accuracy and monitoring for deviations. Maintenance signals include unusual noise, hydraulic leaks, or inconsistent part quality. Failure boundaries are defined by the maximum force and stroke limits, beyond which the press may be damaged.
