Abstract
The present invention relates to a kind of straight sword drill bit, including drill lip, chip area and drillstock, the center of the one end of the drillstock away from drill lip is provided with screwed hole, and described drill lip and chip area is genesis analysis on drillstock, the drill lip is distributed in the side of chip area, and the drill lip is straight sword；The first sword seat and the second sword seat are also sequentially provided between the drill lip and drillstock, and first sword seat is a frustum cone structure, the second sword seat is cylindrical structure.The advantage of the invention is that：Straight sword drill bit of the present invention, drill bit uses straight sword cusp design, it can prepare to position processing stand, it is difficult to train off in process, straight sword is designed to shorten process time simultaneously, and drillstock end is provided with screwed hole, adds the frictional force between drill bit and electric tool, drill slipping effectively is prevented, the service life of drill bit is added；Meanwhile, the first sword seat and the second sword seat are also sequentially provided between drill lip and drillstock, and then add the steadiness of straight sword drill bit.
Description
Technical field
The invention belongs to wood processing field, more particularly to a kind of straight sword drill bit.
Background technology
Timber has the advantages that the lightweight, ratio of strength to weight is high, elasticity is good, impact resistance texture rich palette is attractive in appearance, handling ease,
Important raw material are all listed in from ancient times to the present, and timber industry is because energy resource consumption is low, pollute less, resource has reproducibility, in state
Extremely important status is accounted in people's economy.Product is from the early processing product such as various sawn timbers such as electric pole, mine timber, sleeper of log, development
To the reprocessing product become a useful person, such as various wood-based plates of glued board, fiberboard, particieboard, so that timber industry forms independent
Industrial system.In forest industry, wood-processing industry and chemistry of forest product processing be all forestry cut and transportation follow-up industry, be wood
The important department of material comprehensive utilization of resources.
The drill bit generally drilled is fluted drill, but fluted drill when the small hole in aperture is processed it is impossible to ensure that accurate
Degree, while easily being trained off when processing, easily produces the rotation that offsets, shortens drill bit and use between drill bit and electric tool
In the life-span, extend process time；Meanwhile, the drill bit of existing drilling, drill lip is directly connected to drillstock, and its steadiness is relatively poor.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of easily and fast, can accurately drill and that stability is good is straight
Cutting drill head.
In order to solve the above technical problems, the technical scheme is that：A kind of straight sword drill bit, including drill lip, chip area and
Drillstock, the center of the one end of the drillstock away from drill lip is provided with screwed hole, and described drill lip and chip area is longitudinal direction point
Cloth is on drillstock, and the drill lip is distributed in the side of chip area, and the drill lip is straight sword；Its innovative point is：The drill lip with
The first sword seat and the second sword seat are also sequentially provided between drillstock, and first sword seat is a frustum cone structure, the second sword seat is circle
Rod structure.
Further, the top surface area of the first sword seat is identical with the following table area of the second sword seat.
The advantage of the invention is that：Straight sword drill bit of the present invention, drill bit uses straight sword cusp design, can prepare positioning processing
Point, is difficult to train off in process, while straight sword is designed to shorten process time, drillstock end is provided with screwed hole, increases
Add the frictional force between drill bit and electric tool, effectively prevented drill slipping, add the service life of drill bit；Meanwhile, bore
The first sword seat and the second sword seat are also sequentially provided between sword and drillstock, and then adds the steadiness of straight sword drill bit.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of straight sword drill bit of the present invention.
Embodiment
The following examples can make professional and technical personnel that the present invention is more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
Embodiment
The straight sword drill bit of the present embodiment, including drill lip 3, chip area 2, apex point 1 and drillstock 4, drillstock 4 are fixed on electric tool
On, the central point of punching is directed at using apex point 1, the angle of apex point 1 is 55 ° ~ 65 °, easy fixed center point, accurate positioning, no
Easily train off.3 pairs of processing workpiece of drill lip do cutting movement, and cutting swarf discharges workpiece surface from chip area 1, it is ensured that hole surface
It is smooth, it is ensured that machining accuracy, at the same chip area 1 can discharge processing produce heat, it is to avoid temperature is too high, adds brill
The service life of head；
The center of the one end of drillstock 4 away from drill lip 3 is provided with screwed hole 5, and screwed hole 5 is internal thread clockwise, and drillstock 4 passes through
Screwed hole 5 is spirally connected with electric tool, and the external diameter of drillstock 4 is 10 ~ 15mm, drillstock 4 is stably fixed on electric tool, makes
Drill bit follows swivel head to be rotated；
In addition, the first sword seat 6 and the second sword seat 7 are also sequentially provided between drill lip 3 and drillstock 4, and the first sword seat 6 is a round platform knot
Structure, the second sword seat 7 is cylindrical structure, and the first sword, 6 top surface area is identical with the following table area of the second sword seat 7.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
Art personnel are it should be appreciated that the present invention is not limited to the above embodiments, and described in above-described embodiment and specification is explanation
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
