Abstract
The invention provides a punching drill bit. The punching drill bit comprises a drill bit, wherein the drill bit is provided with a first cutting edge and a second cutting edge; one end of the first cutting edge and the middle position of a tool point of the second cutting edge are of an integrated structure; a tool post is arranged at one end of the second cutting edge; a groove is formed in the other end of the tool post; a first inclined plane and a second inclined plane are arranged on the upper surface of the tool post; the connection part of the first inclined plane and the second inclined plane is a tool point of the tool post; a saw tooth structure is arranged on the tool point of the tool post. The punching drill bit has the beneficial effects that the unique tool bit is designed so that the drilling speed is rapid, the tool bit is not easy to crack, the service life is long and a punched hole is smooth; subsequent construction is facilitated, flying chips are few in a use process and large-scale production is facilitated.
Description
Technical field
The present invention relates to a kind of drill bit, be specifically related to a kind of grooved bit.
Background technology
" electric drill class " product is the conventional products in electric tool, but the large series products of the electric tool had the call.35% is accounted in the production and sales total amount of Chinese electric tool.China's Power Tools Industries is the fairly obvious industry of export-oriented feature, and the electric tool produced every year of the whole industry so far from the nineties in last century, has 85 ~ 90% to be for foreign export.The wherein average occupancy 37.22% of foreign export quantity in the Chinese electric tool total volume of exports of " electric drill " series products.Along with social development, the progress of industry, a new product replaces old product, when each new product is produced, inevitably need to carry out drilling operating, drill bit needs to make medium broken by surge, but when medium is adamantine, comparatively painstaking when using electric impact drill to punch, rate of penetration is lower.Simultaneously blade is with under the impact force action of its edge-perpendicular, and cutter head easily bursts apart.
Thus, the invention is intended to design a performance more excellent, be more applicable for the grooved bit of modern high-strength working.
Summary of the invention
The present invention designs a grooved bit, comprise cutter head, described cutter head is provided with the first blade and the second blade, and described first blade one end and the second blade knife edge centre position are structure as a whole, described second blade one end is provided with tool post, and the described tool post other end is provided with groove;
Described tool post upper surface is provided with the first inclined-plane and the second inclined-plane, and described first inclined-plane and described second junction, inclined-plane are the tool post knife edge, and the described tool post knife edge is provided with broached-tooth design.
Wherein, described groove inner wall polishes smooth, and bottom portion of groove is arcuate structure.
Wherein, described first thickness of knife edge is greater than described second thickness of knife edge.
Wherein, described first blade knife edge place is provided with wire casing.
Wherein, described wire casing is consistent with described first blade knife edge length.
Wherein, also comprise blade, described blade and described cutter head are threaded connection.
Beneficial effect of the present invention: unique segment design makes rate of penetration fast, and cutter head not easily bursts apart, long service life and hole after punching is smooth, is beneficial to subsequent construction, flies to cut few, be more beneficial to large-scale production in using.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of grooved bit of the present invention;
Fig. 2 is the schematic diagram of the tool post of a kind of grooved bit of the present invention.
Detailed description of the invention
The following description and drawings illustrate specific embodiment of the invention scheme fully, to enable those skilled in the art to put into practice them.Other embodiments can comprise structure, logic, electric, process and other change.Embodiment only represents possible change.Unless explicitly requested, otherwise independent parts and function are optional, and the order of operation can change.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.The scope of embodiment of the present invention comprises the gamut of claims, and all obtainable equivalent of claims.In this article, these embodiments of the present invention can be represented with term " invention " individually or always, this is only used to conveniently, and if in fact disclose the invention more than, be not the scope that automatically will limit this application is any single invention or inventive concept.
As Fig. 1, a grooved bit, comprise cutter head, described cutter head is provided with the first blade 1 and the second blade 2, and described first blade 1 one end and the second blade 2 knife edge centre position are structure as a whole, and described second blade 2 one end is provided with tool post 3, described tool post 3 other end is provided with groove 4, described groove 4 when drilling bit high-speed rotary cutting, can be collected useless cutting, reduces and fly the generation of cutting phenomenon;
As Fig. 2, described tool post 3 upper surface is provided with the first inclined-plane 5 and the second inclined-plane 6, and described first inclined-plane and described second junction, inclined-plane are the tool post knife edge 7 of described tool post 3, and the described tool post knife edge 7 is provided with broached-tooth design 8.Described cutter head position increases the design of described tool post 3, mainly smooth in order to what keep boring in mouth metapore, and by broached-tooth design, in high-speed rotation, smooth the polishing of hole inwall, is beneficial to the carrying out of follow-up work.
In some optional embodiments, in order to avoid useless blocking of cutting, described groove 4 inwall will polish smooth, and is arcuate structure bottom described groove 4, is beneficial to the later stage to cleaning of cutting useless in groove.
In some optional embodiments, be greater than described second blade 2 thickness to improve the first blade 1 thickness described in service life, this design can avoid bursting apart of blade in high-speed motion.
In some optional embodiments, described first blade 1 knife edge place is provided with the wire casing 9 for accelerating penetration rate.
In some optional embodiments, described wire casing 9 is consistent with described first blade 1 knife edge length.
In some optional embodiments, also comprise blade 10, described blade 10 is threaded connection with described cutter head, can change at any time when cutter head damages time.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; other are any do not deviate from Spirit Essence of the present invention and principle under the change made; modify; substitute, combination, simplify; all should be the substitute mode of equivalence, all should be included in protection scope of the present invention.
