Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a steel pipe processing and forming device. Background Technique

[0002] When steel pipes are produced and processed, they need to go through procedures such as heating, piercing, heading, cooling, and cutting. After the steel pipes are processed, water is needed to cool and form the processed parts of the steel pipes.

[0003] In the prior art, a cooling and forming device for steel pipe processing with the publication number of CN211218058U adopts the solution of "using a circulating cooling mechanism to cool the processed parts of the steel pipes".

[0004] However, there are still some deficiencies in the above solution. For example, when fixing the steel pipe, one end of the steel pipe needs to pass through the fixing frame, and then the upper clamping pad is driven by the fixing screw rod to cooperate with the lower clamping pad to fix the steel pipe. The operation is relatively cumbersome, and the position of the steel pipe in the cooling chamber is fixed and inconvenient to adjust, resulting in insufficient contact with the coolant sprayed by the nozzle, which easily causes uneven cooling and poor forming effect of the steel pipe. In view of this, the utility model provides a steel pipe processing and forming device. Summary of the Invention
