Description

Extrusion tap convenient for chip removal Technical Field The utility model relates to the technical field of extrusion taps, in particular to an extrusion tap convenient for chip removal. Background The extrusion tap is a novel thread cutter for processing internal threads by utilizing the metal plastic deformation principle. The shape of the screw tap is characterized in that the screw tap has no chip removal groove, only has an oil groove, is mainly a titanized extrusion screw tap and is specially used for processing threads on soft metals with smaller thickness, and the extrusion screw tap is generally used on equipment such as a tapping machine, a drilling machine, a lathe, a milling machine, a processing center and the like and is used for processing the soft metal processing threads with smaller thickness. When in use, the size of the lower hole is required to be selected according to the precision requirement, so that high-precision and high-quality threads can be molded, but the existing wardrobe has some defects, such as: CN220523013U is a chip removing screw convenient to install, the device is matched with a threaded rod, a tapping part, a drill rod, a chip removing groove, a spiral groove and the like, when the device works, after the drill rod is installed at a given position, the screw rod is rotated by a nut, so that the drill rod can be driven to rotate, metal chips, oxide skin and impurities generated in the process of rotating the drill rod in a workpiece can enter the chip removing groove, and after the screw rod is continuously rotated, the chip removing groove is communicated with the spiral groove, and after the screw rod is extruded, the metal chips, the oxide skin and the impurities can enter the spiral groove, so that the resistance generated in the tapping process can be reduced; However, during extrusion tap processing, metal scraps, oxide skin or impurities may be generated on the metal surface due to plastic deformation, and these substances adhere to the tap surface to affect the processing precision and the service life, for example, scraps are embedded into a thread groove to cause dimensional deviation, friction and abrasion are aggravated by the metal scraps, surface oxide skin and granular pollutants mixed in the processing environment generated during extrusion processing, although the extrusion tap does not generate traditional cutting metal scraps, oxide skin and impurities, the adhesive impurities in the processing still need to be cleaned, the prior art lacks an efficient cleaning mechanism, the tap maintenance cost is high, the precision stability is insufficient, and the existing extrusion tap usually relies on manual wiping to clean the impurities, so that the efficiency is low and the surface is easy to damage. Disclosure of Invention In order to overcome the defects and shortcomings in the prior art, the utility model aims to provide the extrusion tap convenient for chip removal.
