Description
Technical Field
The utility model relates to a cutting technical field, in particular to saw bit.
Background
The saw blade is a tool for cutting objects, the existing saw blade has many kinds such as a strip saw blade and a circular saw blade, when the saw blade is used for cutting plates, the circular saw blade is usually adopted, the existing circular saw blade comprises a saw blade body which is approximately circular in shape, the periphery of the saw blade body is provided with a plurality of groups of cutting units which are in a circumferential array, each cutting unit comprises a saw tooth, a saw tooth back and a chip groove, when the plates are cut, the upper end surfaces of the saw teeth are mainly used for cutting, as is well known, when various materials are cut, because the materials have stress, after the cutting is carried out, two divided parts can generate a clamping force to two surfaces of the saw blade body under the action of the stress, and because the action of the clamping force, the resistance to the saw blade can be increased, when serious, the saw blade can be clamped in the plates and can not go forward for cutting, and the saw blade, seriously affecting the use of the saw blade.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a saw bit, can solve the saw bit and block in the course of the work and die and can't carry out the problem of cutting, improve the saw bit and use the reliability.
In order to solve the technical problem, the utility model discloses a technical scheme does:
the utility model provides a saw bit, the saw bit includes saw bit body and the sawtooth of setting on saw bit body circumference, the sawtooth is equipped with the sawtooth tool bit on one side that faces cutting direction, the sawtooth tool bit includes top surface, cutting face, side and back, the top surface intersects with cutting face, side, the back, the crossing limit of top surface and cutting face is the cutting edge, the crossing limit that becomes of cutting face and side is vice cutting edge, the quantity of vice cutting edge is two, two vice cutting edge is greater than the thickness of saw bit body apart from the nearest distance, one side fixed connection that faces cutting direction is faced with the sawtooth in the back.
Preferably, the cutting surface is provided with a concave chip groove.
Preferably, the angle formed between the two minor cutting edges is 0 ° to 30 °.
Preferably, the minimum distance between the two secondary cutting edges is the position of the secondary cutting edge farthest from the center of the saw blade body.
Preferably, the minimum distance between the two secondary cutting edges is 1.2-1.5 times of the thickness of the saw blade body.
Adopt above-mentioned technical scheme, owing to be equipped with two secondary cutting edges, two secondary cutting edge is greater than the thickness of saw bit body apart from the nearest distance for the gap width that produces through saw bit cutting material is greater than the thickness of saw bit body, makes the saw bit body can not rub with the cutting plane of material, avoids appearing the saw bit and blocks the problem of dying and can't cut in the course of the work, improves reliability and the life that the saw bit used, the minimum distance between two secondary cutting edges is the position that secondary cutting edge is the farthest away from the saw bit body centre of a circle, the saw bit of being convenient for cuts the material.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 to 3, fig. 1 is a schematic structural view of a saw blade of the present invention, fig. 2 is a schematic structural view of a saw blade head of the present invention, fig. 3 is a schematic structural view of a saw blade head of the present invention, the saw blade includes a saw blade body 1 and saw teeth 2 arranged on the circumference of the saw blade body 1, the center of the saw blade body 1 is provided with a mounting hole 4, the saw blade body 1 is used for supporting the saw teeth 2 for cutting operation and mounting, the saw teeth 2 are provided with the saw blade head 3 on the side facing the cutting direction, the saw blade head 3 includes a top surface 6, a cutting surface 8, a side surface 5 and a back surface 7, the top surface 6 intersects with the cutting surface 8, the side surface 5 and the back surface 7, the edge where the top surface 6 intersects with the cutting surface 8 is a cutting edge 10, the side edge where the cutting surface 8 intersects with the side surface 5 is a secondary cutting edge 9, the number of the secondary cutting edges 9 is two, the two formed secondary cutting edges 9 are also two, the nearest distance between the two secondary cutting edges 9 is greater than the thickness of the saw blade body 1, when the saw blade is used for cutting, materials are cut through the cutting edges 10 and the secondary cutting edges 9, the width of a gap of a notch of the materials formed by cutting is greater than that of the saw blade body 1, the two divided parts cannot generate clamping force on the two surfaces of the saw blade body 1, the resistance generated on the saw blade is reduced or eliminated, the saw blade is effectively protected, the working reliability of the saw blade is improved, the service life of the saw blade is prolonged, the back surface 7 is fixedly connected with one side, facing the cutting direction, of the saw teeth 2, and the cutting surface 8 is opposite to the back surface 7 and faces the cut materials;
