Abstract: Some scurf and dust still remain on the surface of the steel plate with edge milled for making the SAWL pipe at the workshop of a certain domestic company.Addressing this problem, a newly-designed steel plate surface cleaning device other than the conventional similar devices like the roller brush and chip-removing chains, etc.is used.Elaborated here in the article are the main aspects of the new device, including the structure, the key technical parameters, the major calulation process, the configuration and the work flow.It is emphasized that the device has the advantages such as non-blind zone operation, being free of any residual chip or dust and any leakage as well as full automatic operation.The actual operation result shows that the blowing/sucking device is capable of meeting the requirements for the manufacturing process.
