AI Technical Summary

Technical Problem

In traditional free forging hammers, the blanking anvil used for drawing dumbbell pins can easily cause a jamming step on the dumbbell pin shaft, creating a source of creases that affects strength and service life.

Method used

Design a blanking anvil for a dumbbell pin free forging hammer, including a drawing station and a drawing groove. The first groove in the drawing groove is used to hold the end of the dumbbell pin, and the inner wall of the second groove is used for forging and drawing. The rounded chamfer is used to avoid jamming the step, and a heat dissipation component is set to improve heat dissipation efficiency.

Benefits of technology

This effectively avoids the dumbbell pin from forming a jamming step during forging, improving forging quality and service life, and enhancing the applicability and heat dissipation performance of the billet anvil.
