Abstract
The utility model provides a circular saw blade which comprises a circular cutter body, wherein a central hole is formed in the center of the circular cutter body, a plurality of sawteeth are uniformly arranged on the outer circumference of the circular cutter body, grooves are formed in positions, corresponding to cutting edges, of the sawteeth, and diamond cutter points are embedded in the grooves. The hardness of the knife tip made of the artificial diamond material is higher than that of the original tungsten steel cutting edge, so that the knife tip is not easy to break when in use, and the service life of the saw blade is prolonged by about 20 times.
Description
Technical Field
The utility model belongs to the technical field of cutters and relates to a circular saw blade.
Background
A tungsten steel saw blade is generally adopted for cutting a circuit board substrate made of a composite material in which epoxy resin is clamped in copper foil. However, the cutting edge of the tungsten steel saw blade is easy to crack, the service life is short, the trouble is brought to the cutting processing of the circuit board base material, and the use cost of the saw blade is increased.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: provides a saw blade with long service life.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:
a circular saw blade comprises a circular cutter body, wherein a center hole is formed in the center of the circular cutter body, a plurality of saw teeth are uniformly arranged on the outer circumference of the circular cutter body, grooves are formed in positions, corresponding to cutting edges, of the saw teeth, and diamond cutting edges are embedded in the grooves; a saw groove is arranged between every two adjacent sawteeth, the bottom of the saw groove is shaped in an arc shape, and the back part of the saw groove, facing the front tool face of the diamond tool tip, is shaped in a straight line; the included angle formed between the vertical surface of the diamond tool tip corresponding to the front tool surface of the saw groove and the axis passing through the center of the central hole and the diamond tool tip is 10 degrees.
Compared with the prior art, the utility model has the beneficial effects that:
1. the hardness of the tool nose made of the artificial diamond material is higher than that of the original tungsten steel cutting edge, so that the tool nose is not easy to break when in use, and the service life of the saw blade is prolonged by about 20 times;
2. after the diamond tool tip is worn, the diamond tool tip can be repeatedly used after being polished;
3. due to the design of the shape and the angle of the saw groove, chips generated during cutting of the circular saw blade fall down under the circular saw blade in a concentrated mode in the rotating direction, the chip removal speed of the saw groove is improved, and the service life of the saw blade is further prolonged.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below.
FIG. 1 is a schematic view of a circular saw blade;
FIG. 2 is an enlarged partial schematic view of a circular saw blade;
figure 3 is a schematic view of the construction of a diamond tip.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Examples
A circular saw blade comprises a circular cutter body 10 made of high manganese steel, wherein a center hole 20 is formed in the center of the circular cutter body and is used for clamping the saw blade on a cutting sawing machine. The circular cutter body is evenly provided with a plurality of sawteeth 30 along the outer circumference, the positions of the sawteeth corresponding to the cutting edges are provided with grooves, and diamond cutting edges 40 are embedded in the grooves. Because the diamond is easy to graphitize at high temperature and the size of the diamond tool tip is small, the silver wire welding process is adopted during welding, thereby not only avoiding graphitization, but also effectively supporting the diamond. The hardness of the tool tip made of the artificial diamond material is higher than that of the original tungsten steel cutting edge, so that the tool tip is not easy to break when in use, and the service life of the saw blade is prolonged by about 20 times; after the diamond tool tip is worn, the diamond tool tip can be repeatedly used after being polished.
As an improvement of the embodiment, two side surfaces of the diamond tip gradually narrow from top to bottom; chamfered surfaces 42 (see fig. 3) are provided on both sides of the tip of the diamond tip. The cutting performance of the diamond tool tip is improved by improving the structure of the diamond tool tip.
A saw groove 50 is arranged between two adjacent sawteeth, the bottom 51 of the saw groove is shaped in a circular arc shape, and the back part of the rake face 52 of the saw groove facing the diamond tool nose is shaped in a straight line; the included angle formed between the vertical surface of the diamond tool tip corresponding to the front tool surface of the saw groove and the axis passing through the center of the central hole and the diamond tool tip is 10 degrees. Due to the design of the shape and the angle of the saw groove, chips generated during cutting of the circular saw blade fall down under the circular saw blade in a concentrated mode in the rotating direction, the chip removal speed of the saw groove is improved, and the service life of the saw blade is further prolonged.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
