Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a double-head thread tapping machine. Background Art

[0002] A tapping machine is a machine tool that uses taps to process internal threads. It is the most widely used type of internal thread processing machine tool. Tapping machines are lightweight, flexible, efficient, and have advantages that cannot be replaced by other similar equipment. They avoid the limitations of lathes, drilling machines, or manual tapping, and are time-saving, labor-saving, and not prone to thread rot and tap breakage. They are suitable for all machine tools, mold machinery, plastic machinery, printing machinery, packaging machinery manufacturing plants, engineering machinery, automobile and motorcycle parts, aircraft engines, locomotives, tobacco machinery, and general machinery industries. However, existing tapping machines can only process slots on one side. When a workpiece needs to be tapped on both ends, it is either achieved by connecting two devices in series, or turning the processed workpiece over and placing it in the device to tap the other end. Moreover, when the thread types on the two sides are different, the tapping tool needs to be frequently replaced, resulting in uninterrupted production. Utility Model Content
