Technical Field

The utility model relates to a relevant technical field of saw bit specifically is a convenient prosthetic saw bit.

Background

The saw bit is the general name of the circular cutter of thin slice for cutting solid material, and at present, the saw bit is after using certain cycle, and the sawtooth of saw bit all has the wearing and tearing of different degrees, and, present saw bit still does not have prosthetic function, in order to improve cutting efficiency, always can all change the saw bit of renewal, causes certain wasting of resources, so the design production of this place has made a convenient prosthetic saw bit to in order to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a convenient prosthetic saw bit to solve the problem of proposing among the above-mentioned background art.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a convenient prosthetic saw bit, includes positioning disk and annular repair saw dish, the fixed welding of saw dish is restoreed to the annular is at the radial outer wall of positioning disk, the axial length of annular repair saw dish is 2 times of the axial length of positioning disk, the positioning disk is located annular repair saw dish inner chamber middle section position, the radial outer wall of annular repair saw dish extends with the body has the sawtooth of a plurality of evenly spaced distribution.

Preferably, the annular repairing saw disc and the plurality of saw teeth are made of tungsten-cobalt hard alloy materials.

Preferably, each of the saw teeth has a tapered configuration in a front view cross section.

Preferably, the positioning disc is made of manganese steel.

Preferably, the center of the positioning plate is provided with a positioning mounting hole.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model relates to a convenient prosthetic saw bit, annular through adopting the tungsten cobalt carbide material is restoreed saw disc and a plurality of sawtooth, can restore saw disc and sawtooth outer wall to the annular and polish and restore for the sawtooth remains sharp-pointed sharp state throughout, prolongs the life of whole saw bit, simple and practical.

2. The utility model discloses, all set up through the main cross-section of looking with every sawtooth and be the toper structure, be convenient for treat the cutting member and cut, adopt the manganese steel material with the positioning disk for the positioning disk has very strong support intensity, is difficult for taking place deformation.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a cross-sectional view of an embodiment of the present invention.

In the figure: 1. saw teeth; 2. repairing the saw disc annularly; 3. positioning a plate; 4. and positioning the mounting hole.

Detailed Description

In order to facilitate the use, the embodiment of the utility model provides a convenient prosthetic saw bit. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-2, the present embodiment provides a saw blade convenient for repair, which includes a positioning plate 3 and an annular repair saw disc 2, the annular repair saw disc 2 is fixedly welded on a radial outer wall of the positioning plate 3, an axial length of the annular repair saw disc 2 is 2 times an axial length of the positioning plate 3, the positioning plate 3 is located at a middle position of an inner cavity of the annular repair saw disc 2, and a plurality of saw teeth 1 uniformly distributed at intervals extend from a same body of the radial outer wall of the annular repair saw disc 2.

In the embodiment, when in use, the positioning disc 3 is arranged at the middle section of the inner cavity of the annular repairing saw disc 2, and are welded together, the design aims at that the side walls at the two axial ends of the positioning disc 3 are not flush with the side walls at the two axial ends of the annular repairing saw disc 2, the annular repairing saw disc 2 and the saw teeth 1 are driven to rotate by the rotation of the positioning disc 3 in the using process, the workpiece to be cut is cut, the side wall of the positioning disc 3 is not contacted with the workpiece to be cut, and the positioning disc is tightly arranged on the annular repairing saw disc 2, and the saw teeth 1 are contacted with the workpiece to be cut for cutting, so that the resistance in cutting is reduced on one hand, in addition, the positioning disc 3 is prevented from being clamped, the normal cutting progress is influenced, the abrasion of the positioning disc 3 can be reduced, and after the cutting tool is used for a certain period, can repair 2 and the 1 outer walls of sawtooth to annular restoration saw disc for sawtooth 1 keeps sharp-pointed sharp state all the time.

Example 2

Referring to fig. 1-2, a further improvement is made on the basis of embodiment 1:

annular repair saw disc 2 and a plurality of sawtooth 1 are the tungsten cobalt carbide material, and annular repair saw disc 2 and a plurality of sawtooth 1 through adopting the tungsten cobalt carbide material for annular repair saw disc 2 and a plurality of sawtooth 1 have stronger hardness, so that after using certain cycle, align to polish and restore, guarantee its sharp state.

The main section of each saw tooth 1 is of a conical structure, so that a workpiece to be cut can be conveniently cut.

The positioning disk 3 is made of manganese steel, and the positioning disk 3 is made of manganese steel, so that the positioning disk 3 has strong supporting strength and is not easy to deform.

The positioning mounting hole 4 has been seted up at the center of positioning disk 3, through setting up positioning mounting hole 4, is convenient for install overall structure on the power shaft and uses.
