Process for fast cutting round steel axially

Abstract

The invention discloses a process for fast cutting round steel axially. According to the process, a lifting mechanism and a support mechanism are involved. The support mechanism comprises a flat plate. The two ends of the flat plate are each provided with a vertical plate. The two vertical plates are parallel to each other and installed on the flat plate perpendicularly. A bearing is installed in each vertical plate. A roller is installed between the two bearings. The lifting mechanism is installed on a triangular support and connected with the bottom of the flat plate. According to the process for fast cutting the round steel axially, in the cutting course, the supporting function of two supporting points is always applied to the round steel, so that the horizontal position state of the round steel is kept, and the defect that in the round steel cutting course, due to the function of the gravity of the round steel, one end of a workpiece cut is upwards-warped when the cut is deepened, and thus the cut of the cut round steel is inclined is overcome. Through the mode that rotary handles are arranged on a rotary barrel, force arms can be added, and rotating force is reduced.

Description

technical field [0001] The invention relates to an auxiliary device in the blanking process of cutting tool steel, in particular to a process for rapidly cutting round steel in the axial direction. Background technique [0002] Cutting tools are tools used for cutting, mainly referring to turning tools, reamers, planers, drills, etc. There are two main types in terms of materials: cemented carbide and quenched round steel. The usual cutting tools are cemented carbide as cutting tools Overall, the advantage is that the use time is long, the disadvantage is that the cost is too high, and the hard alloy cannot be fully utilized; there is also a kind of hardened round steel as the basic part of the cutting tool, and the hard alloy is used as the cutting tool blade, the advantage is low cost , The disadvantages are short service life, poor wear resistance, complicated processing technology and low success rate. The manufacturing process of cutting tools mainly includes: material...

AI Technical Summary

Problems solved by technology

In mixed-material cutting tools, cemented carbide is usually used as the cutting edge part of the cutting tool, and quenched round steel is used as the main part of the cutting tool. The cutting edge is welded to the formed cutting tool. Grooving, rough grinding, fine grinding, and welding with cemented carbide edges to form a complete cutting tool workpiece. The cutting process of the cutting tool workpiece is to cut the round steel into sections with a cutting machine. However, the length of the cutting machine’s workbench is certain. , for larger workpieces, it is easy to incline the incision due to the gravity of the workpiece itself during the cutting process, which is not conducive to the centering of subsequent processing
