Frame-Guide-Type Cold (Hot) Forging Press

The frame-guide-type cold (hot) forging press is a core piece of equipment in manufacturing, especially in precision forging and automotive parts industries. It uses immense pressure to plastically deform metal billets within a mold cavity, thereby obtaining precision forgings of the desired shape and size. Below, let's look at the working principle and product features of this machine, shared by Jianlong Hydraulic Technology:

1. Working Principle: 

The main motor drives the flywheel to rotate. After the clutch engages, the energy stored in the flywheel is transferred to the gear transmission system or directly to the crank-connecting rod mechanism. This mechanism converts the rotational motion into a strictly vertical linear motion of the slider along the guide rail. The slider drives the upper mold downwards, closing with the lower mold fixed on the lower worktable, applying immense pressure to the billet to shape it.

2. Core Structural Features and Advantages

2.1 Machine Body Structure: Integral Frame Type

2.1.1 Features: The machine body is a closed frame structure, typically welded from high-quality cast steel or steel plates.

2.1.2 Advantages: High rigidity and strength: The enclosed frame can better withstand the enormous tension and torque generated during forging, resulting in minimal deformation of the machine body.

2.1.3 High precision and stability: Ensures extremely high alignment (concentricity) of the upper and lower dies under long-term, heavy-load working conditions, thus producing precision forgings with extremely small dimensional tolerances.

2.1.4 Long service life: The machine body and main components have high fatigue strength, resulting in a longer service life.

2.2 Guiding system: Precision guide rail slider

2.2.1 Features: The slider is guided by rectangular or cylindrical guide rails on both sides (or four corners).

2.2.2 Advantages:

■ Extremely high motion accuracy: The adjustable and very small guide rail clearance ensures the perpendicularity of the slider movement, and its resistance to eccentric loads is far superior to that of a C-type press.

■ Good resistance to eccentric loads: Even in asymmetrical forging processes, the slider can maintain smooth operation, and it is less prone to jamming or die damage.

■ Reduced Die Wear: Precise alignment reduces uneven die wear, extending die life.

2.3 Comprehensive Performance Advantages

2.3.1 High Energy Utilization: Rigid body with minimal deformation allows more energy to be used for billet forming, resulting in higher efficiency.

2.3.2 Suitable for Automated Production: Stable structure, easy to integrate into automated forging production lines, and compatible with robotic arms, feeders, etc.

2.3.3 Environmentally Friendly: Typically equipped with good sound insulation covers and safety protection devices, resulting in relatively low vibration and noise.
