Manufacturing method of rotor body of internal mixer

Abstract

The invention discloses a manufacturing method of a rotor body of an internal mixer, in which a numerical control technology is adopted for machining. The manufacturing method is characterized by comprising the following steps of: casting, cleaning and modeling a rotor body; establishing a three-dimensional physical model for the rotor body; generating a machining program code; carrying out numerical control machining on the rotor body; welding an alloy to the surface of the rotor body; polishing the surface of the rotor body; and detecting the rotor body; and according to the invention, as the rotor body of the internal mixer is machined by a numerical control technology, the machined outside dimension of the rotor body is greatly improved, the machining quality of the rotor body is improved, the production period is reduced, the production cost is reduced, and the quality of a rubber material of a user in the rubber mixing process is greatly improved.

Description

technical field [0001] The invention relates to a machine for rubber production, in particular to a rotor of an internal mixer, in particular to a method for producing the rotor body of an internal mixer. Background technique [0002] Since the end of the 19th century, people have used various types of internal mixers to mix rubber. The rotor is the core component of the main engine of the internal mixer, and its shape is generated according to strict curves. When operating in groups, consistent actions are required, and the meshing dimensions are tight and reliable. Its manufacturing level is directly related to the feeding and unloading speed, production efficiency and smooth operation of the whole machine. The previous manufacturing process was: casting—sand cleaning—grinding and shaping—machining—welding alloy—grinding—inspection. The rotor billet was first cast and sand cleaned and then sent to the riveting and welding workshop. The riveting and welding workshop place...

Problems solved by technology

The previous manufacturing process is: casting—sand cleaning—grinding and shaping—machining—welding alloy—grinding—inspection. The rotor billet is first cast and sand cleaned and then sent to the riveting and welding workshop. The riveting and welding workshop puts the pair of rotors in a group On the V-shaped iron, by turning the rotor manually, find out the part where the two rotors interfere, mark it with a marker pen, and then manually polish off the excess part, and repeat this until the meshing between the two rotors is smooth. It has been manually polished, but it cannot accurately meet the processing requirements of the drawings. The error of the rotor produced by this method is relatively large, which affects the rubber mixing process parameters such as rubber shear force and filling coefficient in the rubber mixing process, making the quality of the rubber material It is greatly discounted, and because the rotors are processed in groups, in the after-sales service process, if one of the rotors is worn out, two of the rotors need to be replaced together, which is expensive and wastes a lot
