Technical Field

[0001] This utility model relates to the field of rapid separation technology in the iron and steel metallurgical industry, and in particular to a milling cutter disc for mounting square molten iron blades on a milling machine. Background Technology

[0002] With the rapid development of automation and intelligent manufacturing technologies, pre-furnace rapid analysis technology has been widely promoted and applied in the steel industry, and many steel companies have established pre-furnace rapid analysis systems. These systems involve sample preparation and analysis. Sample preparation is primarily done using milling machines, mainly fully automatic and semi-automatic machines. Samples milled include carbon steel, alloy steel, process samples, molten iron from steelmaking, and blast furnace iron. Among these, molten iron from steelmaking, blast furnace iron, and process samples have a carbon content of over 4.0% and high hardness, making milling particularly costly. Currently, imported hardened CBN-inlaid round molten iron milling inserts are used. These are expensive, have a short service life, require frequent replacement, and have long delivery cycles, limiting their application.

[0003] This utility model provides a milling machine tool and connecting device using molten iron inserts, namely a milling machine clamping cutter head, which can realize the connection and fixation between the molten iron square inserts and the milling machine system, solves the problem that square inserts cannot be directly assembled and used, and is conducive to the promotion and application of square molten iron inserts in automated and manual milling machine systems. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a milling cutter head for mounting square molten iron cutting tools on a milling machine.

[0018] A milling cutter holder for mounting square molten iron cutting inserts on a milling machine includes a pull stud and a fixed tool holder. One end of the pull stud is provided with a fixed tool holder, and the other end of the fixed tool holder is fixedly connected with a positioning pull groove. A metal connecting sleeve is provided on one side of the positioning pull groove. One end of the metal connecting sleeve is provided with a metal connecting threaded tube. The other end of the metal connecting threaded tube is provided with an elastic connecting member slot and a barb slot. Connecting barbs and elastic connecting members are inserted inside the small disc of the disc body, and four disc milling cutter fixing brackets are provided on the outside of the large disc of the disc body.
