technical field

The utility model relates to the field of saw blades, in particular to a band saw blade with high performance and fast chip removal.

Background technique

Now there are many kinds of band saw blades produced, mainly focusing on cutting sharpness. Its disadvantages are: for fast cutting and viscous stainless steel and die steel, chip removal is often not smooth, which is easy to cause teething and cutting difficulties.

For the above technical problems, it needs to be improved.

Contents of the invention

In order to achieve the above purpose, the technical solution adopted by the utility model is: a band saw blade with high performance and fast chip removal, which is characterized in that it includes a saw blade body and a saw blade fixed on the saw blade body; the saw blade is along the The saw blade bodies are arranged in groups in the length direction, and the corresponding saw blades in each group have the same shape and arrangement order.

As a preferred solution of the present utility model, there are five saw blades in each group, and the five saw blades are arranged sequentially along the saw blade body and the number of saw teeth of the five are respectively: the first saw tooth R, the second saw tooth L, the second saw tooth Three saw teeth R, fourth saw teeth L and fifth saw teeth M; the first saw tooth R is the same as the third saw tooth R, and the second saw tooth L is the same as the fourth saw tooth L.

As a preferred solution of the present invention, the saw blade is made of hard alloy.

As a preferred solution of the present invention, the front angle θ of the third sawtooth R is 7-10°, the rear angle α is 32-35°; the arc r is 2.5-4.5.

The beneficial effects of the utility model: adopting the above-mentioned structure, the structure is simple and reasonable, the saw blade body is fixedly connected with the saw blade, and the overall firmness is increased; a high-performance band saw blade with fast chip removal is provided; , the ideal saw blade with high viscosity of mold steel; improve sawing accuracy and service life.

detailed description

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

Embodiment: A high-performance and fast chip-removing band saw blade as shown in Figure 1 includes a saw blade body 1 and a saw blade fixed on the saw blade body 1; Arranged in groups, the corresponding saw blades in each group have the same shape and arrangement order; there are five saw blades in each group, and the five saw blades are arranged in sequence along the saw blade body 1, and the number of teeth of the five are: first sawtooth R, second sawtooth L, third sawtooth R, fourth sawtooth L and fifth sawtooth M; the first sawtooth R is the same as the third sawtooth R, the second sawtooth L is the same as the fourth sawtooth L; the saw blade is made of hard Alloy.

The utility model is a band saw blade with high performance and rapid chip removal. The saw blade has the same tooth shape as other cutting tools, and its cutting principle is the same. Like other cutting tools, it has three cutting elements. The degree of sharpness, the rake angle is too small is not sharp, it is not easy to eat the knife, the rake angle is too large, although it is sharp, but the strength of the teeth is not strong enough, it is easy to hit the teeth; the second is the back angle, the back angle is too small, the friction increases during cutting, because The cutting force and the saw teeth are also easy to wear, which affects the sawing life. Although the cutting force is too large, the saw teeth are sharp, but the strength of the teeth is not enough; the third is in the removal of chips, so that the iron chips are easy to break and roll up. Chips and chip storage are the key to the tooth shape design of the band saw blade, and the arc R is especially important. Band saw blade cutting is a complex process involving multiple teeth at the same time, uniform downward feed, and continuous cutting, and has a certain soft cutting. The distance between the tips of two adjacent teeth of the sawtooth is called the tooth pitch t. At present, the domestic and international use inches as the measurement unit, usually how many teeth per inch, the distance between the tip of the sawtooth and the root of the tooth It is called the tooth height h. It is divided into one group according to the left and right divided teeth and normal teeth. Generally, it is divided into a group of 3 teeth, a group of 5 teeth, and a group of 7 teeth. The first saw tooth and the second saw tooth are successively arranged in the repeating unit , the third sawtooth, the fourth sawtooth, the fifth sawtooth, the sixth sawtooth, the seventh sawtooth, etc. Through repeated cutting tests and theoretical calculations, through the changes of tooth height h, tooth diameter t, rake angle θ, relief angle α, and arc r parameters, the chips are refined and rolled into rolls, making them easier to discharge and reducing cutting resistance. , Improve the cutting performance of the band saw blade, improve the performance of the band saw blade, thereby reducing the pressure on the back of the band saw blade, prolonging the service life of the band saw blade, suitable for fast cutting and cutting of stainless steel and mold steel with high viscosity.

Specific parameters: the front angle θ is designed to be 7-10°; 5 teeth are a group, and the 1-5 teeth are divided into R, L, R, L, M; the rear angle α is designed to be 32-35°; the arc r is 2.5-4.5; tooth pitch t and tooth height h depend on how many teeth per inch.

The above description of the disclosed embodiments enables those skilled in the art to realize or use the utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

Although terms such as the reference numeral saw blade body 1 are frequently used in this document, the possibility of using other terms is not excluded. These terms are only used to describe and explain the essence of the utility model more conveniently; interpreting them as any kind of additional limitation is against the spirit of the utility model.
