Abstract

The utility model belongs to the field of an alloy cutter, in particular to an alloy extrusion screw tap, which comprises a screw tap handle part, a screw tap connecting part and a screw tap tapping part integrally installed and formed by hard alloy, wherein the screw tap tapping part is made into a symmetrical prism, each edge is a circular arc edge, and the screw tap connecting part is a step-shaped connecting part. The alloy extrusion screw tap has the advantages that the alloy extrusion screw tap has higher processing efficiency, long cutter service life, better applicability and more reliable processing precision, the H5 level tolerance requirements can be stably reached, the screw threads processed by adopting an extrusion mode can realize better surface quality and higher threaded intensity, the cutting is not generated, workpieces can be easily cleaned, and the rigidity and the firmness of the screw tap are further enhanced.

Description

The alloy thread forming tap
Technical field
The utility model belongs to the alloy cutter field, specifically is a kind of alloy thread forming tap.
Background technology
In field of machining; What the processing of internal thread was adopted at present mostly is that screw tap carries out, but with general screw tap machining screw, precision is not high; The screw tap life-span is low, efficient is low; Though existing in recent years high speed steel screw tap or the high-speed steel alloy screw tap of adopting had large increase on life-span, precision and efficient, its service life, machining accuracy stage efficiency lamp do not reach well-content degree as yet.
Especially, the material of thread forming tap is generally high-speed steel, adopts traditional manufacturing process and complete set of equipments to process, and needs to accomplish production through multiple working procedure, has improved production cost more.
Summary of the invention
The problem that the utility model will solve is how to provide that a kind of production cost is low, efficient is high, precision is high, the alloy thread forming tap of long service life.
The utility model provides following technical scheme:
The alloy thread forming tap, it comprises screw tap shank, screw tap connecting portion and the screw tap tapping portion that is wholely set moulding by carbide alloy, and described screw tap tapping portion is set to four prismatics of symmetry, and every rib is a rounded edges, and the screw tap connecting portion is stepped connecting portion.
The diameter 3mm or the 4mm of described screw tap shank.
The length overall of described alloy thread forming tap is 40-60mm.
Adopted this technical scheme, the alloy thread forming tap has higher working (machining) efficiency, and extrusion speed can reach 15-100m/min; Longer cutter life is arranged, can process 25000-30000 screw; Have better adaptability, same screw tap also can be used for the screw thread processing that through hole also can be used for blind hole; Have more machining accuracy reliably, can stablize and reach H5 level tolerance; The screw thread of fashion of extrusion processing can obtain the screw strength of better surface quality and Geng Gao; Do not produce cutting, workpiece and be easy to cleaning; The rigidity and the robustness of screw tap further strengthen.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to sketch map.
The specific embodiment
As shown in Figure 1; The alloy thread forming tap, it comprises screw tap shank 1, screw tap connecting portion 2 and the screw tap tapping portion 3 that is wholely set moulding by carbide alloy, described screw tap tapping portion 3 is set to four prismatics of symmetry; Every rib is rounded edges 3a, and screw tap connecting portion 2 is stepped connecting portion.
Wherein, the diameter 3mm or the 4mm of screw tap shank.
Wherein, the length overall of alloy thread forming tap is 40-60mm.
