Description

The bands for band of the quick chip removal of a kind of high-performance

Technical field

The utility model relates to saw blade field, specifically relates to the bands for band of the quick chip removal of a kind of high-performance.

Background technology

Present production bands for band is wide in variety, mainly pays attention to cutting sharp.Its shortcoming is: for the stainless steel, the mould steel that cut fast and viscosity is larger, often chip removal is not smooth, easily causes and beats tooth and difficult cutting.

For above technical problem, therefore need to make improvements.

Summary of the invention

For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is the bands for band providing the quick chip removal of a kind of high-performance, the cutting anterior angle of energy control cincture saw blade and row cut relief angle and store the circular arc of iron filings, reach quick chip removal, can facilitate and cut different materials effortlessly, there is higher stability and security simultaneously, effectively reduce cost, improve operating efficiency.

For achieving the above object, the technical scheme that the utility model adopts is: the bands for band of the quick chip removal of a kind of high-performance, is characterized in that: comprise blade bodies, the saw blade be fixed in blade bodies; Described saw blade is the length direction arranged in groups along this blade bodies, and the corresponding saw blade in each group is of similar shape and distributing order.

As a kind of preferred version of the present utility model, the saw blade in each group is five, and five saw blades to be arranged and the sawtooth number of five is respectively: the first sawtooth R, the second sawtooth L, the 3rd sawtooth R, the 4th sawtooth L and the 5th sawtooth M successively along blade bodies; First sawtooth R is identical with the 3rd sawtooth R, and the second sawtooth L is identical with the 4th sawtooth L.

As a kind of preferred version of the present utility model, described saw blade is made up of carbide alloy.

As a kind of preferred version of the present utility model, the anterior angle θ of described 3rd sawtooth R is 7-10 °, relief angle α is 32-35 °; Circular arc r is 2.5-4.5.

The beneficial effects of the utility model: adopt said structure, have simple and reasonable, blade bodies is fixedly connected with saw blade, add overall firmly intensity; The bands for band of the quick chip removal of a kind of high-performance is provided; Being applicable to cutting fast, is sawing stainless steel, the tough desirable saw blade of mould steel; Improve sawing precision and service life.

Accompanying drawing explanation

Fig. 1 is the using state figure of the utility model embodiment.

Reference numeral: blade bodies 1.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model embodiment is elaborated.

Embodiment: the bands for band of the quick chip removal of a kind of high-performance as shown in Figure 1, comprises blade bodies 1, the saw blade be fixed in blade bodies 1; Described saw blade is the length direction arranged in groups along this blade bodies 1, and the corresponding saw blade in each group is of similar shape and distributing order; Saw blade in each group is five, and five saw blades to be arranged and the sawtooth number of five is respectively: the first sawtooth R, the second sawtooth L, the 3rd sawtooth R, the 4th sawtooth L and the 5th sawtooth M successively along blade bodies 1; First sawtooth R is identical with the 3rd sawtooth R, and the second sawtooth L is identical with the 4th sawtooth L; Saw blade is made up of carbide alloy.

The utility model is the bands for band of the quick chip removal of a kind of high-performance, the profile of tooth of saw blade is the same with other cutting tools, its cutting principle is identical, three key elements possessing cutting the same as other cutters, one is anterior angle, and it is the sharpness determining cutter, anterior angle is too little not sharp, be not easy penetration of a cutting tool, although the too large sharp teeth portion insufficient strength of anterior angle, easily beat tooth; Two is relief angles, and relief angle is too little, and cutting is that frictional force increases greatly, and due to cutting force, sawtooth also easily weares and teares, and affects saw cutting life, although relief angle too large cutting force reduction sawtooth is sharp, and teeth portion insufficient strength; Three is the eliminatings in chip, makes iron filings easily disconnect and become web-like, and chip breaking and storage bits are that bands for band tooth Shape Design is crucial, and circular arc R is even more important.It is multiple tooth participation simultaneously, the even complex process to lower feeding, continuous cutting compound that bands for band cuts, and has certain soft cutting.Distance between the crown of adjacent two sawtooth of serrated portion is called tooth pitch t, current domestic continuity is international is measurement unit with inch, be generally per inch how many teeth, distance between the tooth tip portion of sawtooth and its tooth root portion is called tooth depth h, tooth and orthodont is divided to be divided into one group according to left and right, generally be divided into one group, 3 tooth, one group, 5 tooth, 7 one group, teeth, at the first sawtooth, the second sawtooth, the 3rd sawtooth, the 4th sawtooth, the 5th sawtooth, the 6th sawtooth, the 7th sawtooth etc. that repetitive is arranged successively continuously.By cutting test and theory calculate repeatedly, by tooth depth h and tooth footpath t, the change of anterior angle θ, relief angle α, circular arc r parameter, refinement chip also becomes web-like, makes it more easily discharge, reduce cutting resistance, improve the incision performance of bands for band, improve the performance of bands for band, thus reduce the pressure to bands for band back, extend the service life of bands for band, the stainless steel being applicable to cut fast and viscosity is larger, mould steel cutting.

Design parameter: anterior angle θ is designed to 7-10 °; 5 teeth are one group, and a point tooth 1-5 tooth is R, L, R, L, M; Relief angle α is designed to 32-35 °; Circular arc r is 2.5-4.5; Tooth pitch t and tooth depth h determines according to per inch how many teeth.

To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.

Although more employ term such as Reference numeral blade bodies 1 grade in figure herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
