Automatic thread rolling machine and method of fixed-point simultaneous automatic thread-rolling machining of thin cylinder work piece

Abstract

The invention relates to an automatic thread rolling machine and a method of fixed-point simultaneous automatic thread-rolling machining of a thin cylinder work piece. An inner-outer thread rolling mold simultaneous rotating mechanism is arranged on a machine frame, a travel switch boss which is arranged on a boss shaft controls a touch-control travel switch to enable an air cylinder to be communicated and tightly presses the thin cylinder work piece through a pressing mold head, and an advance and retreat knife is controlled through a change gear set and a knife handle swing mechanism which belong to an outer thread rolling mold cutting feed mechanism. The method of the fixed-point simultaneous automatic thread-rolling machining comprises the following steps: by means of adjustment of a bolt on an inner thread rolling mold which is on the main shaft, the inner thread-rolling mold is enabled to revolve a certain angle in advance, a thread mold end head of an outer thread rolling mold is enabled not to contact with a thread mold end head of the inner thread rolling mode all the time, and concave points or scratch can not occur on the inner wall of the thin cylinder work piece. The automatic thread rolling machine and the method of the fixed-point simultaneous automatic thread-rolling machining of the thin cylinder work piece has the advantages of being high-efficient, stable in machining quality of the work piece, energy-saving and high in generality.

Description

technical field [0001] The invention relates to an automatic tooth rolling machine for processing thin cylindrical workpieces and a fixed-point synchronous automatic tooth rolling processing method for thin cylindrical workpieces. Background technique [0002] Thin cylindrical workpieces, such as drinking cups or cup barrels or kettle barrels, need to process internal or external threads. The existing rolling machines for processing these thin cylindrical workpieces use the most primitive manual process. The tool operation control method is affected by the technical proficiency of the workers, and the quality of the workpiece is difficult to control; the other is the hydraulic or pneumatic control tool feed method, which requires programming control and the cost of the hobbing machine is high; moreover, for manual, hydraulic or pneumatic control. For the equipment of the knife, the yield rate of single-thread thin cylinder workpieces can only reach 92%, and the yield rate of...

[0002] Thin cylindrical workpieces, such as drinking cups or cup barrels or kettle barrels, need to process internal or external threads. The existing rolling machines for processing these thin cylindrical workpieces use the most primitive manual process. The tool operation control method is affected by the technical proficiency of the workers, and the quality of the workpiece is difficult to control; the other is the hydraulic or pneumatic control tool feed method, which requires programming control and the cost of the hobbing machine is high; moreover, for manual, hydraulic or pneumatic control. For the knife equipment, the yield rate of single-threaded thin cylinder workpieces can only reach 92%, and the yield of three-threaded thin cylinder workpieces can only reach 76%, which has the problem of low yield.
