Abstract
The utility model discloses a metal hole saw with an improved structure, which comprises a boring cutter body and a drill bit, wherein the boring cutter body is provided with a circle of cutting head of saw-toothed shape; a spring is fastened and wound on the drill bit; and the cutting head is provided with a cutting flow outlet, a first blade cutting surface and a second blade cutting surface. The metal hole saw provided by the utility model has the advantages of excellent property, smooth appearance, integrated body, simpleness and convenience in use and high efficiency; the strength of a saw blade material is increased, so that the boring processing property is ensured; the metal hole saw is conveniently used; and a large amount of cutting processing cost is saved.
Description
Technical field
The utility model relates to a kind of hole making drill, belongs to the machining design field, particularly relates to a kind of metal hole making drill of architecture advances.
Background technology
Hole making drill (cutter) is installed on the common electric drill, just can be easily on arbitrary surfaces such as the plane of various sheet materials such as copper, iron, stainless steel, lucite, sphere, carries out any cutting of circular hole, square hole, delthyrium, straight line, curve.Flexibly, conveniently, safety, of many uses.The accessory of hole making drill mainly contains: support handle, and spring, drill bits etc. support that handle belongs to universal component, and the hole making drill in different apertures is furnished with the support handle of 2 kinds of specifications, and between the 14-32mm of aperture is a specification, and the aperture is a specification greater than 32mm's.
The hole making drill of prior art is in working order the time, and stress point is few often, job insecurity, and the life-span is short, and perforate speed waits shortcoming slowly.The metal hole making drill requires the serrations material to have good especially hardness and intensity, but this certain material needs higher cost, produces bigger cost and difficulty of processing.
Summary of the invention
The purpose of the utility model is to provide a kind of metal hole making drill of new structure, and stock-removing efficiency is high, long service life, and the material consumption is less, reduces use cost.
The purpose of the utility model and to solve its technical problem be that technical scheme below adopting realizes.The metal hole making drill of a kind of architecture advances that proposes according to the utility model; Comprise perforate cutter hub and drill bit; Said perforate cutter hub has the jagged cutting head of a circle; The fastening spring that is wound with on the said drill bit, said cutting head have cutting flow export, the first blade cuts face and second a blade cuts face.
According to the metal hole making drill of the utility model embodiment, the said first blade cuts face and the second blade cuts face be not or not same plane, and itself and transverse horizontal face are an angular range, between 30 °-50 °.
According to the metal hole making drill of the utility model embodiment, the angle ranging from 45 °.
According to the metal hole making drill of the utility model embodiment, the rear portion of said perforate cutter hub has rotating shaft, and the side direction of said rotating shaft offers screwed hole, and said perforate cutter hub is threaded in the rotating shaft.
According to the metal hole making drill of the utility model embodiment, tighten in the said screwed hole and be fixed with screw, the bottom lock of said screw, the centre has cylindrical hole slot.
According to the metal hole making drill of the utility model embodiment, the cutter hub that said perforate cutter hub is made for the high-quality high speed steel material.
By technique scheme, the advantage that the metal hole making drill of the utility model has is: the utility model is a kind of functional, and profile is smooth, and the metal hole making drill of one integrated mass is easy to use, and efficient is high; The intensity of perforate processing characteristics coping saw blade material is high and be able to guarantee, makes things convenient for hole making drill to use, and can practice thrift a large amount of cut costs.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the three-dimensional structure diagram of the utility model.
The specific embodiment
See also shown in Fig. 1 and 2, the metal hole making drill of the architecture advances of the utility model comprises: the perforate cutter hub 10 of toothed, drill bit 20 and rotating shaft 30.This perforate cutter hub 10 has the jagged cutting head of a circle, and this cutting head has cutting flow export 11, the first blade cuts face 12 and second a blade cuts face 13.This first blade cuts face 12 and this second blade cuts face 13 be or not same plane, its with horizontal drill bit and rotating shaft at an angle, between 30 °-50 °, preferred angle is 45 ° to scope greatly, can reach the metal covering cutting effect of the best.This perforate cutter hub is to be processed by the high-quality high speed steel material.
The fastening spring 21 that is wound with on the above-mentioned drill bit 20; The rear portion of this perforate cutter hub 10 has rotating shaft 30, and the side direction of this rotating shaft 30 offers screwed hole 31, and perforate cutter hub 10 is threaded in this rotating shaft 30.In addition, have a screw 40 can be screwed in this screwed hole 31, this screw 40 is a bottom lock, and the centre also has cylindrical hole slot.Have one in vertical direction the bending body of rod (not shown) can insert in this cylindrical hole slot, this screw 40 is tightened or is spun out.
Above-mentioned drill bit 20 can directly be loaded and unloaded in the rotating shaft 30; Have at drill bit 20 under the prerequisite of damage, directly bit change 20 more need not drill bit 20 and changes together with perforate cutter hub 10, has made things convenient for the use of hole making drill drill bit 20 like this, has also practiced thrift use cost.
Above-mentioned sawtooth has the cutting inclined plane, and this inclined plane is that the inclined plane by two differing tilt angles constitutes; Conveniently improve the perforate degree of depth of metal hole making drill, effectively reduce the perforate energy consumption of metal hole making drill.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; So every the utility model technical scheme content that do not break away from, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
