Ring gear or flange processing method

Abstract

The invention discloses a method for processing a gear ring or a flange. The method is characterized in that: putting square steel bars or flat steel bars in grooves of three wheels, extruding the steel bars into a circular spiral shape, and forming circular arc square steel after manual or mechanical cutting; putting the circular arc square steel into a cold bending rolling machine for circular extrusion to make two ends of the circular arc square steel overlap; lifting the two overlapping ends to be aligned by a steel stick; welding the two ends together by a butt welder; polishing expelled weld, burr and the like of welded junction by a polisher after flattening treatment of a hydraulic press to form the shape of the gear ring capable of deep processing; and on the basis of the shape of the gear ring or the flange, sequentially performing turning, hobbing, chamfer processing, high-frequency quenching and tempering to form a finished product, namely the gear ring. The method can effectively control the product processing precision, has the advantages of resource conservation, non-pollution, high work efficiency, quick forming and low production cost, and improves the production efficiency.

Description

technical field [0001] The invention relates to a processing method for a ring gear or a flange, in particular to a processing method for a ring gear or a flange on tractors and tricycles requiring electric start. Background technique [0002] Known ring gears or flanges with different diameters, the specific implementation method is: after cutting the raw material 45# round steel or square billet, heat it with fire and burn it red, beat it into flakes with air, and then punch out the middle with a mold Then use an air hammer to axially forge it into a ring shape, then reheat it with fire, and roll it on the hole reaming machine to roll forge it to the required size. The disadvantages are: wasting coal and electricity, and polluting the environment. Contents of the invention [0003] In view of the shortcomings of the above technical problems, the purpose of the present invention is to provide a method for processing a ring gear or a flange. [0004] Technical scheme of t...
