A combined wire tapping

Abstract

The invention relates to a combined screw tap, which comprises a guide head, wherein the end part of the guide head is provided with a cutter installing seat, a cutter blade installing groove is formed in the cutter installing seat, one side inside the cutter blade installing groove is provided with a dismountable cutter blade , a sleeve connecting end is arranged at one end of the cutter installing seat, the sleeve connecting end and the cutter installing seat are integrally formed, one side of the sleeve connecting end is provided with a sleeve connecting rod, one side of the sleeve connecting rod is provided with a connecting spanner, the cutting outer end of the dismountable cutter blade is higher than the outer ends of first screw threads and second screw threads, the end surface of the guide head at the threaded section side is a first threaded inclined surface, the end surface of the cutter installing sat at the side connected with the guide head is a second threaded inclined surface, and the first threaded inclined surface and the second threaded inclined surface are matched and connected. The combined screw tap has the advantages that the operation is stable, deviation cannot occur, the cutter head hardness is great, the abrasion cannot easily occur, the size is small, the weight is light, the use and the operation are convenient, and the application range is wider.

Description

technical field [0001] The invention relates to a screw tap for threaded mouth products, in particular to a combined screw tap for threaded mouth products. Background technique [0002] The threaded tank mouth made of PPO will be slightly deformed due to temperature and force during the production process, and the products that do not meet the standards will be processed with a thread tap to meet the qualified requirements. [0003] The traditional wire tapping head and body are made of alloy steel. During use, they are rubbed against the PPO material and are easily worn out, resulting in the reduction of the outer diameter of the wire tap, which loses its function, and cannot be replaced and repaired, resulting in the scrapping of the wire tap, and the overall weight Big and not easy to handle. Contents of the invention [0004] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a tool with stable operation...
