The operator belongs to the planing field of machine tool metal processing. It is composed of fixed seat, movable seat, conveying mechanism, centering mechanism, pneumatic pressing plate mechanism, screw drive mechanism and cutter seat mechanism. The centering mechanism is composed of hydraulic motor, gear, rack, pull rod, etc. the centering mechanism of steel plate is installed on the movable seat, which can make equal machining allowance on both sides of steel plate. The utility model is single The planing capacity of the range cutter is up to 6mm, and it can planing both sides of the steel plate at the same time. It has the advantages of high planing capacity, high cutting efficiency and good groove roughness, which ensures the required groove angle and size of the steel plate and the technical requirements before the processing and forming of the steel pipe In the debugging and production of high frequency welded pipe production line, the adjustment of some attached machines is very important, which directly affects the quality of finished products. This paper expounds the application and adjustment of the manipulator in the production line of high frequency welded pipe. It mainly analyzes the floating profiling of the planer cutter and the position of the strip steel controlled by the guide plate and the vertical roller The operator is an auxiliary equipment in the high-frequency straight seam welded pipe, which is usually placed before the entrance of the forming section is clamped. Its function is to process the edge of the strip steel into a certain angle groove and blunt edge, so that the high-frequency welding machine can weld firmly in the production of thick wall pipe and improve the stability of the product. Compared with the edge milling machine, the floating and swinging operation machine of strip steel has the advantages of energy saving (passive planing), safety, etc.
