Key Features of Hydraulic Presses for Stamping Gold Bar and Gold Brick Marks

The core features of hydraulic presses for stamping gold bars and gold brick marks are mainly reflected in three aspects: high-precision mechanical structure, precise speed and pressure control, and intelligent operation and safety design. Below, Jianlong Hydraulic Technology shares some information for your reference!

1. High-Precision Mechanical Structure Features

1.1 Four-Column Three-Plate Structure: This is the most typical mechanical feature of the gold bar stamping hydraulic press.

• Structural Composition: Four columns connect the upper and lower worktables, and the movable plate moves guided by these four columns.

• Precision Guarantee: The vertical accuracy of the movable plate is controlled by four precision guide sleeves, ensuring that the parallelism between any point on the lower and upper work surfaces reaches less than 0.1mm.

• Process Significance: This feature is crucial for gold bar stamping, preventing uneven pressure that could result in one side of the mark being darker than the other, or deformation of the gold bar itself.

1.2 Robust and Durable Working Components

• Piston rod and column treatment: Surface treated with high-frequency quenching and hard chrome plating, providing excellent wear resistance and extending equipment lifespan.

• Robust worktable: Ensures precision and stability during product pressing.

2. Precise Speed and Pressure Control Features

2.1 Master-Slave Cylinder Hydraulic Circuit

• Advanced circuit design: Employs an advanced master-slave cylinder hydraulic circuit, resulting in low oil temperature and high energy efficiency.

• Speed characteristics:

◦ High idle stroke speed: All above 150mm/s, improving production efficiency.

◦ Slow working speed: Adjustable to below 25mm/s, ensuring sufficient metal flow into the fine texture of the mold.

• Cylinder installation: Inverted installation significantly reduces the overall machine height.

2.2 Multi-Working Mode Control

• Constant pressure pressing mode: Stops when the pressure reaches the set value, ensuring high pressing tonnage precision.

• Constant stroke pressing mode: Stops when the slider reaches the set position, ensuring high position control precision.

• Rich Adjustable Parameters: Pressure, stroke, punching speed, holding time, and closing height can all be adjusted independently for convenient operation.

3. Intelligent Operation and Safety Design Features

3.1 Operation and Control Methods

• Multiple Control Methods: Offers both manual and semi-automatic control modes. Manual control allows the upper die to be stopped within any stroke range.

• Automatic Counting Function: Features an automatic counting function for easy production management.

• Position Sensing Control: The punching lower stop position is controlled via a pressure switch and a position sensor.

3.2 Comprehensive Safety Protection

• Photoelectric Protection Device: Can be equipped with an infrared hand guard (light curtain) to protect operator safety.

• Over-travel Protection: Equipped with over-travel protection to prevent equipment overload.

• Emergency Stop: Equipped with an emergency return button to handle emergencies.

3.3 Low-Noise Operation

• Noise Control: When the equipment is in standby mode, the noise level does not exceed 85 decibels, improving the working environment.

These characteristics collectively constitute the core advantages of the hydraulic press for stamping and forming gold bars and gold bricks, enabling it to meet the stringent requirements of precious metal embossing processes for high precision, high controllability, and high safety.
