How Does the Jaw Clamping Mechanism Work in a Flat Forging Machine?

Gaomi Hongfeng Machinery Co., Ltd., a leading manufacturer of forging equipment with over 20 years of experience, continues to deliver high-performance solutions for the global forging industry. Today, we explain one of the most critical components in our Horizontal Parting Die Flat Forging Machines — the Jaw Clamping Mechanism.

What is the Jaw Clamping Mechanism?

In a flat forging machine (also known as a horizontal parting die forging press), the jaw clamping mechanism is the system responsible for securely holding the heated metal billet in place during the forging process. It ensures precise positioning and prevents the workpiece from moving or slipping under high forging forces.

Unlike traditional vertical forging presses, horizontal parting flat forging machines use a unique horizontal die separation design. The jaw clamping mechanism plays a key role in gripping the billet firmly from the sides (horizontally) while the main forging slide performs the upsetting or forming operation.

How the Jaw Clamping Mechanism Works

The jaw clamping mechanism in Gaomi Hongfeng’s flat forging machines typically operates through a combination of mechanical, hydraulic, or toggle-lever systems. Here is a step-by-step breakdown:

Billet Positioning: The heated workpiece (billet) is automatically or manually placed between the left and right clamping jaws. These jaws are precision-machined with high-strength alloy steel for excellent wear resistance.

Clamping Action: Once the billet is in position, the clamping cylinder or toggle mechanism activates. The movable jaw (or jaws) moves horizontally toward the fixed jaw, applying strong, balanced clamping force. In many models, a hydraulic or servo-driven system ensures smooth and powerful clamping with adjustable pressure.

Synchronization and Locking: The jaws are synchronized through a linkage or wedge system to ensure even pressure distribution on both sides of the billet. This prevents deformation or shifting during forging. Advanced models use PLC-controlled systems for precise clamping force and timing.

Forging Process: With the billet firmly clamped, the main slide (ram) moves forward to perform the horizontal forging or upsetting. The strong clamping force keeps the material stable, allowing excellent metal flow and high forming accuracy.

Release and Ejection: After forging is complete, the jaws quickly release the finished part, and an ejector or robotic arm removes the forging, preparing for the next cycle.

This mechanism enables high production efficiency, better material utilization, and superior forging quality with minimal flash.

Advantages of Gaomi Hongfeng’s Jaw Clamping Mechanism
