Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe production, in particular to a straightening device for producing seamless steel pipes for heat exchangers. Background Art

[0002] Stainless steel seamless steel pipe is a steel pipe made by perforating a whole round steel with no welds on the surface. In the production process of stainless steel seamless steel pipe, it needs to be straightened. Through straightening, the bent stainless steel seamless steel pipe can be straightened under the action of external force, so that the product reaches a qualified state. The steel pipe straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. The straightening machine squeezes the bars through straightening rollers to change their straightness. Although it can straighten seamless steel pipes, it is not stable when moving, which is easy to affect the subsequent straightening work of the steel pipe.

[0003] Chinese patent document CN211100899U discloses a straightening device for seamless steel pipe production, including a straightening machine body, a hollow block is attached to the left side wall of the straightening machine body, a bracket is fixedly connected to the bottom side wall of the hollow block, the inner cavity of the hollow block is threadedly connected to the first threaded rod, the top side wall of the first threaded rod is fixedly connected to the handle, the bottom side wall of the first threaded rod is fixedly connected to the inner block, the outer side wall of the inner block is equipped with a push plate, the inner cavity of the push plate is equipped with a round roller, the outer side wall of the bracket is equipped with a sleeve block, the right side wall of the sleeve block is fixedly connected to the side block, the inner cavity of the side block is equipped with a rubber layer, the inner cavity of the rubber layer is interference-connected with a clamping rod, and the top side wall of the clamping rod is fixedly connected to the straightening machine body. The above-mentioned straightening device for seamless steel pipe production has shortcomings. Although the device can achieve straightening of seamless steel pipes, it has limitations.
