Description

Technical Field

[0001] This utility model relates to the field of roll forging technology, and more specifically, to a roll forging machine that facilitates mold replacement. Background Technology

[0002] A roll forging mill is a high-efficiency forming machine that uses dies on two or more rotating rolls to continuously plastically deform a billet to obtain the desired cross-sectional shape. It is widely used in automotive parts, agricultural machinery parts, tool manufacturing, and other fields.

[0003] Based on the above, the inventors have discovered that currently, the dies of roll forging machines are usually one-piece. When it is necessary to replace the die, it is necessary to disassemble and install bolts one by one before the die can be removed. This operation is cumbersome, time-consuming, and labor-intensive, affecting production efficiency. Furthermore, the difficulty in changing the die makes it difficult for the equipment to flexibly adapt to the processing needs of different products, limiting its application range. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a roll forging machine that facilitates die replacement, aiming to achieve a more practical and valuable solution.
