Description

Novel hard alloy milling cutter

Technical Field

The utility model belongs to the technical field of the carbide, especially, relate to a novel carbide milling cutter.

Background

In the process of welding railway rails, welding slag and raised heads are produced on a joint, welding seams on the top surface and two side surfaces of a rail head are treated in use, the conventional treatment mode is that after the joint is tempered and cooled to the atmospheric temperature, the welding seams on the top surface and two side surfaces of the rail head are directly ground to be flat, when the welding seams are too large, a flat shovel is used for removing a part of welding waves, then an electric hand-held grinding wheel is used for grinding the welding seams to be flush with the rail head, and finally a file or fine abrasive paper is used for smoothing the grinding surfaces to eliminate large traces, so that the treatment mode is long in time and high in cost, a milling cutter is used in the prior foreign treatment mode, the advantage is that most of redundant welding slag is directly removed by one-step forming under the condition that steel is welded, convenience and rapidness are high, but the foreign milling cutter has the defects of high price and short service life, in order to the above situation, the utility model provides a new-type milling cutter of high price/performance ratio, it has used heat-resistant steel as the matrix, and blade department has melted and has covered high temperature alloy and unique heat treatment mode that high temperature resistant and wear resistance are all good, then makes through advanced technology processing, makes the product have convenient to use, and is longe-lived, does not glue the sediment, indeformable, can keep advantages such as blade sharpness for a long time to the price is reasonable, is the fine product of a cost performance ratio.

However, the cutter head part has a simple structure and low cutter strength, and the rear cutter handle is positioned only by outer threads, so that the positioning precision is insufficient, and the milling precision is influenced.

Disclosure of Invention

The utility model aims at providing a novel carbide milling cutter to solve the problem of mentioning in the background art.

In order to achieve the above purpose, the utility model discloses a following technical scheme: the utility model provides a novel carbide milling cutter, includes the convex cutter head, the handle of a knife, convex cutter head one end is equipped with the fixed station, the fixed station right-hand member is equipped with the impeller, be equipped with the fixed orifices on the impeller, the impeller right-hand member is equipped with the handle of a knife, it has wear pad to inlay on the handle of a knife, convex cutter head surface is equipped with two-sided cutting edge, the convex cutter head is connected with the handle of a knife through the fixed station.

Preferably, the convex cutter head is made of stainless steel, and an alloy layer is laid on the convex cutter head.

Preferably, the tool shank is provided with a chip groove.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, appearance reasonable in design loads and unloads conveniently, makes welding tumour surfacing after pushing away, the surplus is even, and for the preface provides convenience of polishing, the convex cutter head has chooseed for use no magnetism, heat-resisting, rust-resistant stainless steel material, and the alloy-layer has then chooseed for use hardness moderate, high temperature wearability is good, the special alloy material of no magnetism, great improvement life, the cutting edge part durable of messenger's product just with indeformable.
