Description

A kind of hot-cutting saw blade

Technical field

The utility model discloses a kind of hot-cutting saw blades, belong to machinery field, and in particular to a kind of hot-cutting saw blade.

Background technology

Saw blade for metal hot-cutting is a kind of metal rolled industry and enterprise commonly parting tool, is mainly used in round steel high temperature Hot State sawing.Since Rolling Production is mostly state of working continuously.So the height of saw blade self performance and performance is to guarantee fund The continuity for belonging to Rolling Production has larger impact.

Since stocking sawing is the state of working continuously, cutting-rate requires equally higher.Stocking usually has higher anti- Tensile strength and larger sawing area, therefore saw blade will produce prodigious resistance in sawing workpieces.The adjoint noise of ordinary hot Also have field personnel compared with major injury.Resistance energy consumption of the saw blade in sawing accounts for 40% or so of total energy consumption.

In use, if the frictional heat that sawing generates cannot discharge in time, saw blade sheet body cannot be timely for saw blade It is cooling.So that sheet body generates wooden dipper song because of frictional heat, then deform, reduces saw life.

Utility model content

The utility model aim aims to solve the problem that high energy consumption in stocking sawing process, the big problem of noise.It is proposed that one kind is used for The environmentally protective hot saw piece of large-scale circular sawing machine, the low noise that lowers consumption.Saw blade is set to reduce the friction between sheet body and workpiece in sawing process Probability reduces frictional force.To reduce binding, noise is reduced, realizes the environmentally protective function of hot saw piece.It realizes above-mentioned practical new The technical solution of type is:

A kind of hot-cutting saw blade, including：Saw bit matrix, the saw bit matrix is in the form of annular discs, in the saw bit matrix Heart position is equipped with centre bore, and the edge of the saw bit matrix is equipped with sawtooth, and the crown region of the sawtooth is with centre bore Center, which is equipped with, is thinned annulus.

Further, the crown of each sawtooth is designed with thin structure, and the thin structure is two axis in crown The recess of each thinned 1mm on face, the recess thin structure on crown 1mm, each sawtooth crown radially Thinned annulus is collectively formed.

Further, the saw bit matrix is in its horizontal direction, at upper 2/3rds radius of distance center position, setting Multiple fabrication holes.

Further, saw bit matrix the diameter 1400mm--2200mm, thickness 10mm--16mm.

Further, the surface roughness of the saw bit matrix is 12.5 μm.

The utility model has the advantage of：

The hot saw piece processed according to this method, the superperformance for having consumption reduction low noise environmentally protective.With ordinary hot saw blade It compares, teeth portion has and the concentric thinned annulus in annular saw center.The friction probability between sheet body and workpiece is effectively reduced when sawing, is subtracted Less friction.Reduce energy loss 30%-40%.Effectively reduce noise content 20%-30%.

Specific implementation mode

It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field The identical meanings of understanding.

It should be noted that term used herein above is merely to describe specific implementation mode, and be not intended to restricted root According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative It is also intended to include plural form, additionally, it should be understood that, when in the present specification using term "comprising" and/or " packet Include " when, indicate existing characteristics, step, operation, device, component and/or combination thereof.

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings

As shown in Figure 1 and Figure 2, the consumption reduction low noise hot saw chip architecture that the present embodiment provides:Saw blade sheet body is a band center The disk in hole, disk periphery process the sawtooth of different number by modes such as milling, grinding, laser cuttings.

As shown in Figure 1 and Figure 2, in a typical embodiment, saw bit matrixPiece body thickness 12mm, saw The method of the turning of sheet matrix surface or grinding is processed into the surface roughness of Ra=12.5, four be distributed on saw bit matrix Fabrication holeFabrication hole is arranged in the radial direction, at distance center 2/3rds.After modulation treatment, saw blade sheet body Hardness >=25HRC.

The spacing of sawtooth takes 9.97mm, and the class tooth root root circle structure between two sawtooth is radius R=2mm arc-shaped depressions, Class tooth profile structure is the circular arc of radius R=9mm, and sawtooth crown locally does independent quenching, and lonneal is handled, Ying Du≤ 50HRC。

As shown in figure 4, the two sides of disk working width 1mm, depth 1mm and ring concentric with saw blade center at outer rim Band.

Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention The limitation enclosed, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not Need to make the creative labor the various modifications or changes that can be made still within protection scope of the present invention.
