The 315T four-column hydraulic press is a popular industrial solution for a wide range of pressing applications. It features a robust structure, multi-function capability, and high-precision control. It efficiently performs metal sheet stretching, powder compaction, hot pressing, and other forming operations. This machine also offers outstanding benefits including energy efficiency, reliable safety, and easy maintenance, making it ideal for mass production in automotive components, metal fabrication, composite materials and other key industries.
Structure of a Four-Column Hydraulic Press
Three-Beam Four-Column Structure
The 315 T four-column hydraulic press features a sturdy frame construction, consisting of an upper beam, slider, worktable, and four columns. Integral welding or casting processes eliminate internal stress, ensuring exceptional machine body rigidity. For instance, the upper beam and slider are fabricated from high-quality steel plates via welding, while the columns undergo medium-frequency quenching and chrome plating. This robust design enables the machine to withstand high-intensity pressing operations without deformation, making it ideal for high-precision positioning processes such as thin sheet stretching and precision forming.
Four-column guide structure
The four-column hydraulic press features precise slider movement, guided by its four columns to ensure even distribution of blank holder force. This design boosts material flow stability significantly while cutting down product scrap rates-an essential advantage for metal stretching processes. It effectively prevents material breakage and thickness inconsistencies that often result from uneven stress application during forming.
Diverse Processing Fields
★ Thin Plate Stretching: Our 315T four-column hydraulic press is ideal for forming thin-walled components like automotive body panels and stainless steel tableware. By fine-tuning pressing speed and pressure parameters, it delivers smooth, wrinkle-free stretching results-critical for maintaining the integrity and aesthetics of delicate workpieces.
★ Powder Metallurgy Forming: For powder metallurgy processes, the 315T four-column hydraulic press exerts consistent pressure to compress metal powders (including iron powder and copper powder) into custom shapes with uniform density. This makes it a reliable choice for producing high-precision parts such as gears, bearings, and other mechanical components that require tight dimensional tolerances.
★ Straightening & Press Fitting: Equipped with a movable worktable, the 315T four-column hydraulic press efficiently handles shaft straightening tasks and press-fits components like bearings and gears. Its stable pressure output ensures precise assembly, reducing errors and improving the overall quality and durability of finished products.
★ Composite Material Hot Pressing: Our 315-ton four-column hydraulic press is widely used for hot pressing resin manhole covers and PMC (polymer matrix composite) products. Through precise control of temperature and pressure during the hot pressing process, it ensures thorough material curing, resulting in composite products with strong structural integrity, excellent durability and consistent performance.
Control System
PLC Fully Automatic Control
The 315T four-column hydraulic press uses a PLC to automate the motion sequence, such as rapid descent, slow pressing, pressure holding, and return stroke, reducing manual intervention and improving production efficiency. For example, in helmet production, the PLC can precisely control the stretching speed and pressure, ensuring consistent thickness and strength in each helmet.
Servo Motor
The 315T four-column hydraulic press is equipped with a servo motor and electro-hydraulic proportional valve, enabling precise adjustment of pressure, speed, and stroke. For example, in metal stretching processes, the servo motor can dynamically adjust the stretching speed to prevent material breakage; in powder molding, the proportional valve ensures stable pressure and improves product density uniformity.
Human-Machine Interface
The touchscreen digital display system supports parameter setting and real-time monitoring. Operators can intuitively adjust parameters such as pressure, speed, and stroke, and store multiple sets of process formulas for easy mold changeover and production of different products.
Application Cases
1. Automotive Industry: An automotive parts manufacturer uses a 315T four-column hydraulic press to produce engine brackets. The stamping effect is excellent, while simultaneously improving fatigue strength, meeting both strength and safety requirements.
2. Metal Products Industry: A stainless steel tableware company uses a 315T four-column hydraulic press to complete the stretching and forming of bowls and plates, improving both product qualification rate and production efficiency.
3. Composite Materials Industry: An environmental protection company uses a 315T hydraulic press to press resin manhole covers. Through a hot-pressing process, the manhole covers achieve higher density, significantly better load-bearing capacity than traditional cast iron manhole covers, and are also corrosion-resistant and have a longer service life.
