Embodiment 2

[0021] Embodiment 2: A milling compound machining center is used, which can replace CNC lathes, vertical machining centers (four-axis), center hole grinders, cylindrical grinders, and vertical milling machines. The size of the bar is Φ190×630, and the center holes at both ends are processed by ordinary lathes, and the outer circles of each rough car to figure 2 state. Then, it is clamped once on the turn-milling compound machining center. With the double-spindle drive and the center frame, all the processes of rotor turning and milling can be completed, the center of both ends is corrected, each journal is semi-finishing, and the rough milling line (general milling cutter) , fast milling method), using wiper blade turning tool to finish turning each bearing file (turning instead of grinding), milling keyway, drilling, and threading. Finally, the rotor profile is finely ground by the grinding center.

[0022] This embodiment has a high utilization rate of equipment, and the ...

Abstract

The invention relates to the technical field of screw compressor rotor production, in particular to a screw rotor production technique. The screw rotor production technique can ensure the machining quality, is short in machining period and low in cost, and comprises the steps of rough turning, rough milling of a molded line, finish machining of an axle spindle, central hole machining, finish machining of a molded surface, key slot milling, drilling and tapping. The screw rotor production technique is characterized in that rough milling of the molded line is conducted on general equipment through a general milling cutter, and finish machining of the molded line is conducted through an adjustable grinding wheel which is formed through finishing of a grinding center of molded surface finish machining equipment.

Description

technical field [0001] The invention relates to the technical field of screw compressor rotor production, in particular to a screw rotor production process. Background technique [0002] The screw rotor is the core component of the screw compressor. The development of the rotor profile determines the progress and efficiency of the compressor to a large extent, and the processing technology of the rotor is an important factor to ensure the quality of the rotor. With the rapid development of science and technology, the market has higher and higher requirements for product quality, and the replacement cycle of screw rotors is getting shorter and shorter, and the precision requirements are getting higher and higher. The processing methods of traditional screw rotors are greatly challenged. . [0003] Conventional machining process of screw rotor: blank, rough machining of shaft, rough machining of profile, finishing of shaft, finishing of center hole, finishing of profile, and ...
