1results about How to "Reduce initial resistance" patented technology

This utility model relates to the field of tapping guides, and discloses a tapered guide head for preventing jamming of thread tapping guides. It includes a main body, a tapered head fixedly connected to the bottom of the main body, a spiral drilling edge on the surface of the tapered head, a handle fixedly connected to the top of the main body, an oil inlet at the top of the handle, a reservoir inside the tapered head, an oil passage inside the main body, the reservoir communicating with the oil inlet via the oil passage, and multiple channels inside the tapered head arranged in a ring at equal angular intervals. In this utility model, lubricant is delivered to the outlet through the oil inlet, reservoir, oil passage, and channels, forming a continuous lubricating film. When the tapping machine rotates the tapered head and rubs against the workpiece, it reduces frictional resistance, minimizes heat accumulation, and prevents the tap from overheating and deforming.
