Abstract
The invention relates to a cutting tool for paper-making industry, wooden product industry and other light industries. It is formed from two portions of base body and tool blade, and the blade portion is such product made up by using high-hardness wear-resistant electrode through the processes of build-up welding, grinding and forming, and can implement cutting working under the mal-condition, and can ensure its service performance, and its wear rate is low. Said invention can save energy source, its production period is short and production cost is low.
Description
The present invention relates to a kind of cutting tool of paper-making industry, woodwork industry and other light industry.
At paper-making industry, woodwork industry and other light industry, employed cutting knife generally all is made of matrix and blade two parts, and matrix adopts irony or mild steel manufacturing more, and blade adopts heat treated steel such as can quench and so on to make.The general procedure of making is that elder generation carries out the machining of matrix and blade on request respectively, makes needed shape; After both respectively are heated to uniform temperature, carry out hot rolling and close; Quench to rolling cutting knife blank after closing then, a series of heat treatment such as tempering; Carry out grinding shaping processing at last, make the cutting knife product.The deficiencies in the prior art part mainly is: technology and the process complexity, loaded down with trivial details of making cutting knife; Need equipment, the labour of usefulness many, trouble in the management; Corresponding energy resource consumption is big, and the production cycle is long, the cost height.
The objective of the invention is to avoid weak point of the prior art, and the high-hardness wear-resisting cutter that a kind of technology is simple and cost is low product is provided.
Can take following technical scheme to realize purpose.High-hardness wear-resisting cutter still is made of matrix and blade two parts, but the blade section on the matrix is to become with the built-up welding of high hardness wear-resisting welding rod, again the product of grinding-shaping.
Satisfying under the above-mentioned technical request, as for the specific constructive form of matrix, blade, size, both proportionate relationships, the material of selecting for use and the global shape of high-hardness wear-resisting cutter, width, thickness etc. all can be taken the circumstances into consideration to set according to using needs.It is good to make cutting ability with the technical program, and the high-hardness wear-resisting cutter product that process is simple, cost is low.
The relative prior art of the technical program has following advantage and effect:
1, the blade of high hardness wear-resisting welding rod built-up welding formation is organized as granular magnetization thing, martensite and austenite, and it can bear the machining under the bad working environments fully, guarantees serviceability, and rate of depreciation is low and stable, and crack resistance is extremely strong;
2, technology is simple, make easily, and not preheating before the weldering, postwelding need not heat treatment, has saved multiple operation; Need the equipment of usefulness and the labour is few, the investment is little, easy in the management, save time and save trouble;
3, save the energy, with short production cycle, the cost of product reduces.
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Accompanying drawing is a kind of structural representation of high-hardness wear-resisting cutter.
Matrix 1 part in the high-hardness wear-resisting cutter can adopt irony, mild steel or other metal material, manufactures required shape by prior art, and this point and prior art do not have difference.And its blade 2 parts one are used as the part of cutting, or are referred to as blade, are to constitute with the corresponding site built-up welding of high hardness wear-resisting scolder at matrix.In this way constitute the blank of cutting knife, again blank is carried out needed machined, as be ground to the cutting knife goods.The high hardness wear-resisting welding rod can adopt commercial articles.
Among the high-hardness wear-resisting cutter embodiment shown in the drawings, blade 2 parts on the matrix 1 are to adopt the built-up welding of TD60 high hardness wear-resisting welding rod to become, again the product of grinding-shaping.The cutting ability of present embodiment and result of use the best.
Claims (2)
1, a kind of high-hardness wear-resisting cutter is made of matrix and blade two parts, it is characterized in that: the blade section on the matrix is to become with the built-up welding of high hardness wear-resisting welding rod, again the product of grinding-shaping.
2, high-hardness wear-resisting cutter as claimed in claim 1 is characterized in that: the blade section on the matrix is to adopt the built-up welding of TD60 high hardness wear-resisting welding rod to become, again the product of grinding-shaping.
