Description

Technical Field

[0001] This utility model relates to the field of cold heading machine exhaust gas collection technology, and more specifically, it relates to an exhaust gas collection device for a cold heading machine. Background Technology

[0002] Cold heading is a metal forming process that rapidly forges metal at a lower temperature. It is commonly used to produce various screws, nuts, and other parts. During this process, metal particles or dust may be generated and float in the air. Therefore, exhaust gas collection devices are needed to reduce the impact of exhaust gas on the external processing environment and thus ensure the health and safety of workers.

[0003] However, traditional exhaust gas collection devices only have a filtration mechanism and cannot remove metal particles from the exhaust gas, resulting in poor exhaust gas treatment. If the exhaust gas is discharged directly, it will still harm the health of workers.

[0004] Furthermore, existing exhaust gas collection devices have a relatively simple structure. If exhaust gas is discharged simply by filtration, it cannot remove fine particulate matter in the exhaust gas. Utility Model Content
