Gear fine blanking and gear ring pressing plate type fine blanking process principle description

The technical principles of gear fine blanking and ring gear press plate fine blanking are as follows, for reference and understanding.

Gear fine blanking:

Precision blanking is different from ordinary blanking. Precision blanking is a mold with a special structure and small blanking gap. It uses a precision special punch to make the metal material under high static pressure and under the best plasticity. Therefore, better quality blanking parts can be obtained.

gearFor fine blanking, a powerful press-plate fine blanking process is commonly used.The ring gear pressing plate type is one of the most important.

Gear ring pressing plate type fine blanking process principle:

1. Feeding

The press rises to separate the upper and lower dies, and the sheet material enters the die.

2. Press material

The die is closed, and the ring gear pressing plate, the punch and the ejector make the sheet material in a high pressure state.

3. Blanking

The punch punches into the sheet material, and the sheet material is sheared and deformed by the punch until the punching is completed.

4. Molding

When the punch returns, the ejector pressure is released, and the workpiece is stored in the concave mold.

5. Discharge

The punch releases the sheet material, the gear ring pressing plate leaves the plate, the ejector, and the ejector ejects the workpiece from the concave mold.
