Embodiment Construction

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0015] Such as Figure 1-2 As shown, a cylindrical broaching tool includes a tip reference block 1, a guide block 2 and a tool holder 14. One side of the tip reference block 1 is fixed with a guide block 2, and one side of the guide block 2 is fixed with a first The neck 3, one side of the first neck 3 is provided with a first neck cutting edge 5, one side of the first neck cutting edge 5 is an end cutting edge 4, and the other side of the first neck cutting edge 5 is fixed There is a second neck cutting edge 6, a third neck cutting edge 7 is fixed on one side of the second neck cutting edge 6, and a fourth neck cutting edge is fixed on one side of the third neck cutting edge 7 8. One side of the fourth neck cutting edge 8 is fixed with a fifth...

Abstract

The invention discloses a cylindrical broaching knife. The cylindrical broaching knife comprises a tip reference block, a guiding block and a knife hilt, wherein the guiding block is fixedly arrangedon one side of the tip reference block; a first knife neck is fixedly arranged on one side of the guiding block; a first neck cutting blade is arranged on one side of the first knife neck; one side ofthe first neck cutting blade is an end surface cutting blade; a second neck cutting blade is fixedly arranged on the other side of the first neck cutting blade; and a third neck cutting blade is fixedly arranged on one side of the second neck cutting blade. By the design of the first neck cutting blade, the second neck cutting blade, the third neck cutting blade, the fourth neck cutting blade andthe fifth neck cutting blade, the cutting efficiency can be improved, the circumstance that knifes are changed repeatedly is avoided, the cylindrical broaching knife is simple and convenient to operate, and meanwhile, the service life of the knife is prolonged; and by the design of a first sleeking blade and a second sleeking blade, rapid transition of cutting can be met, and the cutting qualityand efficiency are improved; and by the design of a table-shaped connecting block, chippings can be guided out rapidly.

Description

Technical field [0001] The invention relates to a tool, in particular to a cylindrical broaching tool. Background technique [0002] Knives are tools used for cutting in mechanical manufacturing, also known as cutting tools. Most of the tools are machine-used, but there are also hand-used. Since the tools used in mechanical manufacturing are basically used for cutting metal materials, The term "tool" is generally understood as a metal cutting tool. [0003] In the use of traditional cylindrical broaching tool, due to poor heat dissipation, it is easy to cause damage to the tool, which greatly reduces the service life. In addition, the traditional tool has only one cutting edge during processing, and needs to be replaced frequently during multiple processing. , It reduces work efficiency. If the chips in the cutting process cannot be discharged in time, it will also affect the quality and efficiency of processing. Therefore, we have made improvements to this and proposed a cylindri...
