1. What is Mechanical Press: 

What is Mechanical Press: A mechanical press machine is a powerful device used in manufacturing to cut, stamp, bend, or form materials—typically metal—into desired shapes. It operates with high precision and speed, making it indispensable for mass production in various industries, from automotive to aerospace. The machine’s structure is built from welded steel plates, which are strengthened through artificial aging and treated with shot blasting passivation to enhance corrosion resistance. This design minimizes deformation and improves rigidity, essential factors for maintaining accuracy and longevity.

The JH21 Series: A Closer Look

The JH21 Series Open Back Mechanical Power Press Machine by GUANGDUAN is an example of modern engineering in metal forming. With its welded steel body and enhanced rigidity, this machine is designed for durability, high performance, and safety. The open-back structure provides operators with easy access, making it suitable for various large-scale stamping and pressing tasks.

2. How Does a Mechanical Power Press Machine Work?

The Basic Working Principle

Mechanical power press machines use a crankshaft-driven mechanism to apply force, shaping the material with dies or tools. The process starts with the material, or “stock,” being placed on the bottom die. The top die then comes down to press or cut the material, applying the required shape or marking. The upper die is connected to a crankshaft through a connecting rod. As the crankshaft rotates, it moves the upper die downward, impacting the material against the bottom die.

The Role of the Motor and Flywheel

A powerful motor drives the flywheel, which stores rotational energy to keep the press running smoothly. The energy from the flywheel is transmitted through gears to the crankshaft, allowing the machine to execute each press or punch with consistency and precision. This mechanism is the heart of the machine, delivering the required force to shape or cut materials efficiently.

3. Key Features of the JH21 Mechanical Press Machine

Pneumatic Wet Friction Disc Clutch and Brake

One standout feature of the JH21 Series is its pneumatic wet friction disc clutch and brake. This system provides several benefits, including increased durability, lower noise levels, and enhanced safety. Wet friction clutches tend to last longer and operate more quietly than dry clutches, reducing wear and tear on the machine and creating a safer environment for operators.

Heat-Treated Gear and Sliding Pairs

Both the gear pairs and sliding pairs in the JH21 mechanical press are heat-treated, quenched, and precision-ground. This careful manufacturing process ensures smooth transmission and high precision. The heat treatment enhances the strength and durability of these components, essential for maintaining accuracy and smooth movement over time, even under high-speed and high-force operations.

4. Advanced Control and Automation

PLC-Controlled Operation

One of the hallmarks of the JH21 series mechanical press machine is its integration of PLC (Programmable Logic Controller) technology. The PLC system allows for precise control over the machine’s functions, enabling greater accuracy and repeatability. This digital control system can also be programmed for different tasks, making it easier to adjust settings quickly for various types of production requirements.

Compatibility with Automatic Feeding Devices

The JH21 mechanical press can be connected with automatic feeding devices, enabling it to function within an automated production line. This capability allows for continuous, uninterrupted operation, ideal for high-volume manufacturing environments. When configured with a feeding system, the press can become part of a single-machine or multi-machine stamping production line, achieving a high level of production efficiency.

5. Safety and User-Friendliness

Two-Hand Button Operation and Hydraulic Overload Protection

Safety is paramount when operating heavy machinery, and the JH21 Series ensures protection with a standard two-hand button operation. This feature requires the operator to use both hands to initiate the press, preventing accidental triggering and reducing the risk of injury. Additionally, the machine is equipped with hydraulic overload protection, which helps avoid excessive force, reducing the risk of damage to both the machine and the tooling.

Automatic Lubrication System and Adjustable Control Heights

The automatic lubrication system is a key feature in models above 1100KN, ensuring that all moving parts are consistently lubricated, minimizing wear and extending the machine’s life. In models above 630KN, an adjustable control height feature allows operators to control the height of the press stroke, offering greater versatility for different applications.
