Detailed Description
For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.
Example 1
As shown in fig. 1, a welding saw blade special for fire fighting comprises a circular base body 1, a mounting hole at the center of the base body 1, chip removal holes 3 uniformly distributed along the circumference inward at the edge of the base body 1, and a cutter head 4 welded between every two adjacent chip removal holes 3; preferably, the clearance hole 3 is a strip-shaped pore with a circular end, the cutting head 4 comprises an arc-shaped substrate 41 and a diamond blade 42 at the edge of the substrate, the substrate 41 is welded with the base body 1, and the diamond blade 42 is formed by brazing metal powder with diamond particles at the edge of the substrate 41.
This embodiment is when using, and the base member that will weld have tool bit 41 is connected with the cutting motor through the mounting hole at center to it rotates along with cutting motor's operation, and wherein tool bit 41 chooses hard metal tool bit for use, and the diamond cutting edge 42 contact by the object of cutting at its edge, under the effort of high-speed rotation, with the object segmentation, the piece flies down from chip removal hole 3, and in the cutting process, the hard big fracture that is difficult to of tool bit, even break, it can to weld the tool bit once more.
Example 2
As shown in fig. 1, a welding saw blade special for fire fighting comprises a circular base body 1, a mounting hole at the center of the base body 1, chip removal holes 3 uniformly distributed along the circumference inward at the edge of the base body 1, and a cutter head 4 welded between every two adjacent chip removal holes 3; preferably, the clearance hole 3 is a strip-shaped pore with a circular end, the cutting head 4 comprises an arc-shaped substrate 41 and a diamond blade 42 at the edge of the substrate, the substrate 41 is welded with the base body 1, and the diamond blade 42 is formed by brazing metal powder with diamond particles at the edge of the substrate 41; as shown in fig. 2, the edge of the substrate 41 is further provided with a plurality of gullets 43 with uniform intervals, preferably, the gullets 43 are formed in a sharp-angled concave shape, after the coating with diamond particles is coated, the shape characteristics of the gullets are weakened, and a diamond blade 42 with gullets is formed.
In use, the substrate with the cutting head 41 welded thereon is connected with a cutting motor through a central mounting hole, and rotates along with the operation of the cutting motor, the diamond blade 42 at the edge of the substrate contacts with the object to be cut, and the chips fly off from the chip removal hole 3; under the effect of the high-speed rotation of base member, diamond blade 42 has tooth's socket 43 in addition, and it is easy with the segmentation of object to in cutting process, its tooth's socket department plays certain cushioning effect, makes the effort of being cut between article and the tool bit weaken, makes the tool bit be difficult to the fracture, even break, it can to weld the tool bit once more.
