Abstract

The invention relates to the field of machining, and specifically relates to a quick-changing hard alloy finishing broach. The quick-changing hard alloy finishing broach is characterized by comprising a broach body and a plurality of blades, wherein a plurality of blade grooves are formed in the broach body, and one blade and a press block adjacent to the blade and used for tightly pressing the blade are arranged in each blade groove. The quick-changing hard alloy finishing broach disclosed by the invention has the advantages that higher machining accuracy and machining quality are achieved due to unique combination and design, the durability of the broach is improved, and the service life of the broach is prolonged.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a quick-change hard alloy finishing broach. Background technique [0002] In the field of modern mechanical processing, the broaching process is more and more used in various industries due to its high processing precision, good dimensional stability, and long service life. However, there are many parts that are difficult to process materials, such as nodular Cast iron workpieces, high-temperature alloy workpieces, titanium alloy workpieces, etc., broaches made of high-speed steel materials, or even broaches made of powdered high-speed steel, when processing the above-mentioned difficult-to-machine materials, the broach wears quickly and the broach life is short. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing broaches are easy to wear and have short service life. [0004] In order to solve the above-menti...
