Description

Technical Field

[0001] The invention belongs to the technical field of steel pipe processing, and in particular relates to an automatic steel pipe turning and receiving device. Background Art

[0002] In the process of steel pipe production, in order to realize automated production, a turning mechanism will be set between the stand and the roller. The function of the turning mechanism is to realize the transition connection between different equipment of steel pipes and realize rapid and automated production. At present, the most commonly used ones are flat drag turning mechanism or direct turning hook mechanism. The flat drag mechanism can turn the material stably, but the equipment body is heavy, the required rotation space is large, and the investment cost is also large; the direct turning hook mechanism has a simple structure, but the turning process is rough and the impact force is large, which can easily cause equipment damage and steel pipe quality problems. How to simultaneously meet the requirements of simple structure, light weight, no damage to the equipment it serves, and minimal impact on the quality of steel pipes is very critical.

[0003] In general, fixed baffles are installed to prevent the steel pipe from rushing out of the roller, and the impact of the steel pipe falling is borne by the receiving roller. This structural form has the following problems: ① The steel pipe has a large impact force on the roller, which causes the roller bearing seat bolts to loosen and the bearing seat to break, reducing the service life of the bearing; ② The moment the steel pipe falls onto the roller, there is not only a downward impact force, but also an outward force rolling out of the roller, which hits the baffle and has a great impact on the roller body; ③ The entire impact process will cause damage to the steel pipe.
