Abstract

The utility model relates to a bimetal band saw and circular saw blade alloy, including a hard alloy crown face, two front and back-angle grinding faces and one small crown face. In detail, two planes are taken as two front and back-angle grinding faces, both of which shape a proper angle. In addition, one extended end of the two front and back-angle grinding faces is overlapped with two edges of the small crown face and the other end of extension shares the same sideline of the crown face, thus forming an assembly with front and back-angle grinding face and crown face. Besides, the assembly extends vertically towards both of its sides to shape an assembly with two symmetric steps, which is welded onto the tooth of band and circular saw blade through hard alloy, thus providing a band and circular saw blade characterized by lower heat transfer, high shearing capacity and abrasion resistance applicable speedy, efficient and quality cutting.

Description

The tooth portion alloy of bi-metal bandsaw blades and circular saw

Technical field

The utility model relates to industrial cutting technology field, relates to a kind of band saw and circular saw that cuts usefulness.

Background technology

At present, the matching used tooth of band saw and circular saw portion material all is the M42 high-speed steel that adopts from external import, because the difference of the production technology of each enterprise, the M42 high-speed steel costs an arm and a leg on the one hand, the measured data of its heat-treating atmosphere stove can not be consistent on the other hand, causes the quality instability of product.Simultaneously, the cutting difficult to machine material as: in stainless steel, tool steel, the heat-resisting alloy steel, the inefficiency of its cutting, tooth portion life-span of band saw and circular saw is short, its section of poor quality do not meet the technological requirement that Modern High-Speed is produced.

Summary of the invention

The purpose of this utility model just provides a kind of hard tooth portion alloy of optimizing structure that has.

Technical solution of the present utility model is: comprise an arc surface of a carbide alloy, angle, two front and back grinding face, a little arc surface; The angle grinding face is two planes before and after described two, becomes a suitable angle between described two planes; One end of two plane extensions and two coincident of a little arc surface, the part that the other end extends overlaps with two sidelines of arc surface, and form one have before and after the integral body of angle grinding face and arc surface, described integral body is extended to the both sides of its vertical direction, form a integral body with two steps, the part that described step is high is angle, a front and back grinding face, and the part that described step is low is an arc surface, and angle, described front and back grinding face has the height that doubles at least than arc surface.

Angle between described two planes is that 60 degree are between 68 degree.

Described arc surface has and identical installation half warp of installed surface on band saw and the circular saw.

Good effect of the present utility model is:

1, owing to the tooth portion welding carbide alloy at band saw and circular saw, the high speed of the hardness height of carbide alloy, wear-resistant, so energy on the one hand, the low heat conduction power of efficient, high-quality cutting and anti abrasive material; The use amount of carbide alloy is 1/3rd to 1/4th of common alloy band saw and a disk sawtooth portion on the other hand, thereby more energy-conservation, economic environmental protection.

2, single arc surface contact is adopted in welding, and in the alloy of similar shape, directly effective contact area of its welding is maximum, and is single arc surface, thereby has only a welding stress face, can effectively reduce the thermal stress that welding produces, and has improved weld strength.

3, carbide alloy adopts mould setting compacting, the stock removal at cutting angle, front and back is minimum, help the stable of band saw and disk sawtooth portion grinding process, and adopt diamond wheel grinding power light, the product grinding face is highly polished, the physical dimension of product and precision high conformity, product automation degree height, high efficiency.

4, weld part of this carbide alloy and cutting portion junction adopt arc surface to strengthen, help the raising of carbide alloy bulk strength, help in working angles carbide alloy and be cut the most rational contact-making surface of storeroom, reduce frictional force, improved stock-removing efficiency, more helped chip removal, simultaneously in tooth portion grinding process, reduce stock removal, improved grinding accuracy, improved tooth portion fineness.

5, because backing is independent heat treatment, backing does not need to contain the alloy spring steel of high vanadium, get final product with common high-strength spring steel, thereby cost greatly reduces.

Description of drawings

Fig. 1 is the side view of the utility model carbide alloy;

Fig. 2 is the front view of the utility model carbide alloy.

Be labeled as shown in the accompanying drawing: 1, carbide alloy, 2, strengthen arc surface, 3, angle, front and back grinding face, 4, arc surface, 5, little arc surface.

The specific embodiment

Describe concrete device and the implementation detail that the utility model proposes in detail with regard to above-mentioned accompanying drawing below.

As shown in Figure 1 and Figure 2: the utility model comprises angle grinding face (3) before and after the arc surface (4), two of a carbide alloy (1), a little arc surface (5); Angle grinding face (3) is two planes before and after described two, and becoming a suitable angle, this angle between described two planes is that 60 degree are between 68 degree; The end that angle grinding face (3) extends before and after two and two coincident of a little arc surface (5), the part that the other end extends overlaps with two sidelines of arc surface (4), and form one have before and after the angle grinding faces (3) and the integral body of arc surface (4), described integral body is extended to the both sides of its vertical direction, form a integral body with two symmetrical steps, the part that described step is high is angle, a front and back grinding face (3), and the part that described step is low is arc surface (4); Angle, described front and back grinding face (3) has the height that doubles at least than arc surface (4).

As mentioned above, at the step place of angle, front and back of the present utility model grinding face (3), can be the angle of one 90 degree, strengthening arc surface (2) at one as shown in Fig. 2 as the utility model with arc surface (4).On manufacturing process, still structurally all has certain advantage because strengthen arc surface (2).And arc surface (4) has the unexistent advantage of other structures, particularly be installed to certain appointed positions when getting on when this arc surface (4), described assigned address is the tooth portion of band saw and circular saw normally, and described tooth portion has installation half warp identical with arc surface (4).Such arc surface (4) just need not be located especially to product, thereby has the quick and convenient advantage of installation, and manufacturing process is simple, and is with low cost.

Carbide alloy of the present utility model (1) not only can be applied to the tooth portion of band saw and circular saw, can also be installed to other all instruments with cutting characteristic and get on.A kind of band saw, circular saw and cutting element with carbide alloy 1 tooth portion can be provided thus, and this band saw, circular saw and cutting element can be at a high speed, efficient, high-quality cutting particularly low heat conduction power, high shear force and anti abrasive material.

Though the utility model is by detailed being described of the foregoing description, do not change under the situation of general idea of the present utility model not can on content do suitable adjustment, the scope of its adjustment also will fall in the protection domain of the present utility model.
