Abstract
The utility model discloses a kind of spiral Woodworking flat drills.It includes the chit drill ontology being made of the segment of cutting that drillstock, flat linkage section and linkage section hypomere are formed, the segment of cutting of chit drill ontology includes the cutting edge portion that linkage section hypomere side section shape is isosceles triangular structure and the positioning apex point that cutting edge portion end is formed, the tow sides of positioning apex point are both provided with tip cutting edge, the both sides of cutting edge portion are provided with the cutting tooth that cross sectional shape is zigzag structure, cutting tooth forms complete spiral yarn shaped, the helix surface of the cutting tooth is curved surfaces, and cutting edge is formed on curved surfaces.With the above structure, stock-removing efficiency can be greatly improved by the cutting edge of arc, and it is time saving and energy saving when cutting, in addition, the positioning apex point with tip cutting edge being arranged can carry out rapidly being accurately positioned and ensure that setting accuracy on work in initial procedure, reasonable in design, process efficient and convenient, high in machining efficiency and processing quality is good.
Description
Technical field
The utility model is related to a kind of machining tool, specifically a kind of spiral Woodworking flat drill.
Background technology
Existing Woodworking flat drill generally comprises the flat cutting head connected on drillstock and drillstock, and there have in cutting head to be fixed
Position apex point, the both sides for positioning apex point are provided with oppositely arranged cutting blade, and existing this structure can realize boring requirement,
But due to the limitation of its structure design, it is difficult to continue deeper into when drilling to half and pierces, is usually all to need to be taken out weight
It newly pierces, punches in this way time-consuming so that processing quality cannot be guaranteed.
Invention content
The technical problem to be solved by the utility model is to provide a kind of high spiral of laborsaving, drilling efficiency easy to use
Woodworking flat drill.
In order to solve the above-mentioned technical problem, the spiral Woodworking flat drill of the utility model includes by drillstock, flat connection
The chit drill ontology that the segment of cutting that section and linkage section hypomere are formed is constituted, the segment of cutting of chit drill ontology includes linkage section hypomere
Side section shape is the cutting edge portion of isosceles triangular structure and the positioning apex point that cutting edge portion end is formed, and positions apex point
Tow sides be both provided with tip cutting edge, the both sides of cutting edge portion are provided with the cutting tooth that cross sectional shape is zigzag structure,
Cutting tooth forms complete spiral yarn shaped, and the helix surface of the cutting tooth is curved surfaces, and cutting is formed on curved surfaces
Cutting edge.
The linkage section is set as the guiding surface seamlessly transitted with cutting edge portion.
The chit drill ontology is made of high-speed tool Steel material.
After above-mentioned structure, due to the cutting tooth of spiral yarn shaped structure being arranged in cutting edge portion and by cutting tooth
Curved surfaces formed cutting edge, stock-removing efficiency can be greatly improved from there through the cutting edge of the arc, and cut
It is time saving and energy saving when cutting, in addition, the positioning apex point with tip cutting edge of setting, can carry out rapidly being accurately positioned and initial
It ensure that setting accuracy on work in the process, reasonable in design, processing is efficient and convenient, and high in machining efficiency and processing quality is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the spiral Woodworking flat drill of the utility model.
Specific implementation mode
With reference to the accompanying drawings and detailed description, drill bit is slided to the self-cooled of the utility model to make further specifically
It is bright.
As shown, the spiral Woodworking flat drill of the utility model, includes by drillstock 1, flat linkage section 2 and connection
The chit drill ontology 4 that the segment of cutting 3 that section hypomere is formed is constituted, described chit drill ontology 4 preferably use high-speed tool Steel material system
At the segment of cutting of chit drill ontology 4 includes the flat structure that linkage section hypomere side section shape is isosceles triangular structure
The tow sides of the positioning apex point 6 for the flat structure that cutting edge portion 5 and cutting edge portion end are formed, positioning apex point 6 are respectively provided with
There are tip cutting edge 7, tip cutting edge 7 to be staggeredly arranged and be located at respective side, the both sides of cutting edge portion 5 are provided with section shape
Shape is the cutting tooth 8 of zigzag structure, and cutting tooth 8 forms complete spiral yarn shaped, and the helix surface of cutting tooth is arc table
Face forms cutting edge 9 on curved surfaces.
Further, described linkage section 2 is set as the guiding surface seamlessly transitted with cutting edge portion 10, thus improves
Processing quality.
