Abstract
The invention discloses a punching drill. The punching drill comprises a drilling tool bit, a drill body connected with the drilling tool bit and a drill tail connected with the drill body, wherein the drilling tool bit comprises a first cutting part and a second cutting part; the first cutting part is provided with a thick tool and a thin tool; one end of a tool point of the thick tool is fixedly connected to the middle position of a tool point of the thin tool; the second cutting part is formed by symmetrically arranging two groups of drilling tools on the drilling tool bit; the positions of tool points and the drill tools and the tail end of the first cutting part are located on the same horizontal line. The punching drill has small flying chips, small vibration amplitude and low noises; mental and body injuries to workers by long-time and high-strength drilling work are reduced; a good working environment can be easily provided and the pollution to the environment is reduced.
Description
Technical field
The present invention relates to a kind of drill bit, be specifically related to a kind of grooved bit.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Punching is as operation indispensable in routine work, it is important that the excellent degree of grooved bit seems particularly, grooved bit is now economical and practical, but variation is few, structure is single, lack novelty, in use there is following shortcoming: 1, noise is larger, be unfavorable for the noise pollution reducing job site, affect surrounding enviroment, under being in noise for a long time simultaneously, workmen is produced uncomfortable, workmen's mood seriously can be made impatient, affect the progress of work, and the person is damaged; 2, fly to cut many, easily unnecessary trouble is caused to workmen, time serious, irremediable injury can be caused to workmen; 3 vibratory sensations are strong, and in work progress, the vibrations of high strength, make the joint of workmen produce uncomfortable, shake for a long time, can cause irremediable injury to joint, add the burden of society.
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 novel grooved bit, the brill tail that described grooved bit comprises drill head, the brill body be connected with described drill head and is connected with described brill body, described drill bit comprises the first cutting portion and the second cutting portion, described first cutting portion is provided with thick cutter and thin cutter, and described thick cutter knife edge one end is fixedly connected on described thin cutter knife edge centre position; Described second cutting portion be two groups of drill symmetries be arranged on described drill head, the end of described drill knife edge position and described first cutting portion is in the same horizontal line.
Wherein, described brill body is provided with drill flute, and described drill flute height is equal with described brill height degree, and the described drill flute degree of depth is 1mm.
Wherein, described brill body diameter is less than the diameter of described drill head.
Wherein, described brill tail diameter is greater than the diameter of described brill body.
Wherein, described drill head and described brill are as integrative-structure, and described brill body and described brill tail are for being threaded.
Wherein, the top of described brill tail and described brill body junction are provided with chamfering.
Beneficial effect of the present invention: fly to cut little, vibration amplitude is little, and noise is low, reduce long-time, high strength bore operation to operating personnel bring at heart, infliction of body, be conducive to provide good operating environment, reduce the pollution of environment.
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 first cutting portion 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 kind of grooved bit, comprise the drill 1 being responsible for cutting, the brill body 2 of the responsible extension be connected with described drill head and the brill tail 3 being used for connecting that is connected with described brill body 2, drill bit 1 as illustrated in figs. 1 and 2 comprises the first cutting portion 4 and the second cutting portion 5, described first cutting portion 4 is provided with thick cutter 401 and thin cutter 402, and described thick cutter 401 knife edge one end is fixedly connected on described thin cutter 402 knife edge centre position; Described second cutting portion 5 be two groups of drill symmetries be arranged in described drill 1, the end of described drill knife edge position and described first cutting portion 4 in the same horizontal line, too high easily violent in boring procedure vibrations, too lowly easily in boring procedure, be not easy to reaming, also may directly block, boring cannot be continued, so be optimal selection at same level line.
When drilling bit high-speed is selected, first cutting portion 4 is responsible for tentatively punching to plane, by arranging with the position of described thin cutter 402 described thick cutter 401, and the relatively existing cutter head of drill head is less, can can reduce drill bit sound and reduce seismaesthesia in boring procedure,, then carry out reaming by the second cutting portion 5, in the high-speed rotation of drill described in reaming procedure, further hole carried out to the plane forming preliminary hole and expand.
In some optional embodiments, described brill body 2 is provided with and flies to cut for storage, reduce fly to cut dance in the air phenomenon drill flute 6, described drill flute 6 height is highly equal with described brill body 2, and the described drill flute degree of depth is 1mm.
In some optional embodiments, be less than the diameter of described drill 1 to better more be beneficial to described brill body 2 diameter of boring.
In some optional embodiments, be greater than the diameter of described brill body 2 to better more be beneficial to described brill tail 3 diameter of boring.
In some optional embodiments, be structure as a whole with described brill body 2 to better more be beneficial to the described drill of boring 1, described brill body 2 and described brill tail 3, for being threaded, facilitating when bit damage more bit change, are beneficial to and reuse.
In some optional embodiments, top and described brill body 2 junction of described brill tail 3 are provided with chamfering 7, the setting of chamfering be play drill bit drill-through after cushioning effect, prevent from being directly stuck on described brill tail 3, cause very large vibrations, avoid causing unnecessary injury to workmen.
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.
