Description

Technical Field

[0001] This utility model relates to the field of forging equipment technology, specifically to a swing-type rotary feeding platform. Background Technology

[0002] As a heavy forging equipment, the efficiency of the auxiliary feeding device of the free forging hydraulic press directly affects the overall production cycle. Traditional feeding mechanisms mostly adopt a fixed structure, which occupies a large area and is difficult to adapt to compact factory layouts. Some improvement schemes attempt to improve flexibility by using independent hydraulic cylinders to drive the lifting and rotating mechanisms, but additional interlocking devices are required to ensure safety, resulting in response delays and increased costs. Therefore, the existing mechanisms still have the following problems: (1) the rotation and lifting actions are separated, resulting in complex structures and poor synchronization; (2) the positioning relies on manual intervention, resulting in low automation; (3) the hydraulic drive components are loosely arranged and easily subject to space constraints.

[0003] Therefore, there is an urgent need for a high-efficiency feeding device that integrates rotation and lifting functions and is suitable for confined spaces. Utility Model Content
