Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to a turning machine and a turning method thereof. Background Art

[0002] A turning machine is needed to turn the rolled steel coils during the production process of the steel coils. However, most of the turning machines in the prior art can only initially position the products. The position of the turned material changes on the horizontal plane before and after turning. The steel coils are relatively heavy and have requirements on the placement angle. The current turning machines cannot meet the above requirements. Since the steel coils need to be placed on a fixture, the fixture is easy to fall off and the steel coils are easy to scatter during the turning process. Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a turning machine and a turning method thereof. Summary of the invention

[0003] The main technical problem solved by the present invention is to provide a turning machine and a turning method thereof, which can quickly center the material and drive the material to rotate to a specified angle. During the turning process, the jig and the steel coil can be pressed to prevent the jig from falling off and the steel coil from scattering.

[0012] The jig anti-slip swing arm mechanism comprises a rotating shaft, an anti-slip swing arm and a swing cylinder. The two rotating shafts are rotatably mounted on a flip frame, an anti-slip swing arm is mounted on the rotating shaft, and the swing cylinder is rotatably mounted on the flip frame.
