Understand Structure · Clarify Principle: Practical Operation Basics of Yihui Casting Hydraulic Press

The hydraulic press (Oil Hydraulic Press) is a "heavyweight" core equipment in Yihui Casting's production process line. Its stable operation and precise operation are key to ensuring the quality of casting products and improving production efficiency. It is also an important component of Yihui Casting's one-stop casting solution. Mastering the structural composition and working principle of hydraulic presses is not only a fundamental requirement for job operations, but also an important prerequisite for standardizing operations, avoiding equipment failures, and ensuring production safety. This training will focus on the structure of Yihui Casting Hydraulic Press and its working mechanism based on Pascal's Law, providing a systematic explanation to help everyone clarify the equipment operation logic, master the operation points proficiently, and lay a solid theoretical foundation for subsequent standardized operations and efficient completion of hydraulic production process. It will also assist Yihui Casting in the stable supply of overseas export products.

Comprehensive disassembly: structure and working principle of hydraulic press

Purpose: The stamping, pressing, bending, correction, hydraulic pressure, and pressing processes of metal and non-metal plates are suitable for various casting processing needs of Yihui Casting. To complete the above purposes, it must be combined with molds and widely used in casting production scenarios in overseas markets such as Southeast Asia, the Middle East, and Europe and America.

Structural features: The frame type body has good rigidity, stable operation, simple structure, sensitive action, convenient operation, safety and reliability, easy installation, easy maintenance, and small footprint. It meets the core requirements of overseas customers for efficient and easy to maintain casting equipment and is one of the main export equipment of Yihui Casting.

structural composition

The Yihui Casting Hydraulic Press is mainly composed of the following structures, and the core components have undergone strict quality inspection to meet the long-term stable production needs overseas:

Rack: Top Beam, Column, Workbench, made of high-strength materials to ensure equipment rigidity and service life;

Hydraulic cylinder: cylinder body, piston rod, seals, excellent sealing performance, reduces hydraulic oil leakage, and meets green production standards;

Hydraulic system: oil tank, pump, valve group, pipeline, stable hydraulic transmission, suitable for different overseas working conditions;

Electrical control system: operation buttons, control modules, easy to operate, can optimize the operation interface according to overseas customer needs;

Safety devices: protective cover, emergency stop button, infrared protection, in compliance with CE safety certification requirements, ensuring the safety of operators;

Pressure gauge: Accurately displays pressure for real-time monitoring by operators, ensuring machining accuracy.

working principle

Hydraulic transmission is based on Pascal's Law: pressure is equally transmitted in a closed liquid, which is the core principle of efficient operation of hydraulic presses and the technical basis for precise pressure control of Yihui casting hydraulic presses.

Practical operation standards: startup, operation, and shutdown

Pre startup inspection: Check the hydraulic oil level, pressure gauge accuracy, and safety device integrity to avoid equipment failure and ensure safe startup. This is a key step in extending the service life of the hydraulic press.

Operation process: Equipment comprehensive inspection → Turn on power switch → Turn on emergency stop switch → Press up switch → Set working pressure → Set travel → Set holding pressure → Set holding time → Press down switch → Install mold → Hydraulic processing → Equipment maintenance → Record production process, follow the standardized operation specifications of Yihui Casting throughout the process, and adapt to the production management needs of overseas customers.

Startup steps: Connect the power → Start the motor → Run the machine empty (15 minutes), ensure that all components of the equipment are running normally before putting it into production to reduce equipment wear and tear.

At work: Accurately set pressure and stroke → start pressing → real-time observation of equipment operation status, timely handling of abnormalities to ensure product processing accuracy and equipment safety.

Shutdown: Turn off the motor → cut off the power, clean the equipment, prepare for the next startup, and comply with overseas equipment operation safety regulations.

Safety regulations and maintenance

Safety Specifications

1. Overloading and overtraveling operations are strictly prohibited to avoid equipment damage and safety accidents;

2. It is strictly prohibited to insert hands or body into the work area. Protective goggles and helmets should be worn throughout the process to ensure the personal safety of operators;

3. Clearly locate the emergency stop button, immediately stop the equipment if any abnormalities are found, and promptly contact maintenance personnel for handling, in compliance with international industrial safety standards.

Maintenance and Care

Regular maintenance is the core of extending the service life of hydraulic presses and ensuring stable operation of equipment. It is also a key focus of after-sales service provided by Yihui Casting to overseas customers

1. Regularly replace hydraulic oil (6-12 months), select hydraulic oil that meets international standards, and ensure stable operation of the hydraulic system;

2. Regularly check the wear of seals and replace them in a timely manner to prevent hydraulic oil leakage;

3. Regularly clean the fuel tank and filter to avoid impurities affecting the accuracy of equipment operation;

4. Regularly tighten connectors, inspect electrical circuits, ensure the safety and stability of equipment electrical systems, and adapt to long-term overseas production needs.

Yihui Casting Technology Co., Ltd. was established in 2003. After more than 20 years of accumulation, Yihui has now developed into a national high-tech enterprise that integrates research and development, production, sales, consulting, installation, and training of lost wax casting equipment, and provides one-stop solutions for metal casting. Yihui Casting Technology products include metal casting equipment, casting wax, graphite products, quartz products, etc., which are exported to Southeast Asia, the Middle East, Europe, America and other regions. The company has its own R&D team, which independently develops and produces automated vacuum die-casting machines, G20 vacuum bead scattering machines, and intelligent system D3 vacuum pressure casting machines, breaking the industry's long-standing dependence on imported high-performance jewelry equipment.
