Description

Technical Field

[0001] The present invention relates to the technical field of anchor chain manufacturing, and in particular to a bar transition lifting device for a link making machine. Background Art

[0002] Anchor chains and mooring chains are important components for positioning offshore floating bodies. They are usually produced by a four-station rotating unit. The four stations correspond to link making, flash welding, deburring, and grooving (shaping) respectively. There is a rotating device in the middle of the unit to control four short chains respectively. Before link making, the round steel needs to be cut into small sections, heated to the process-specified temperature, and then transported to the link making station. The traditional feeding device uses a roller conveyor to transfer the bars. Since the same unit needs to produce multiple link chains of different specifications, when finally sent to the link making machine, the misalignment at the link welding joint will occur due to different bar diameters, affecting the production efficiency and the quality of link making. Therefore, it is necessary to propose a bar transition lifting device for a link making machine to solve the above problems. Summary of the Invention
