Abstract
The utility model relates to a bimetal hole opening saw, which can make holes on a metal plate. The utility model comprises a saw blade with saw teeth, a stem and a central drill, wherein, the saw blade and the central drill are fixed to the stem; the saw teeth on the blade presents inwards and outwards staggered arrangement at intervals. The utility model has the advantages of high speed of hole providing, smooth cutting, small vibration, high durability, etc.
Description
The utility model belongs to a kind of metal perforating device.
At present, existing metal perforate saw is made up of saw blade, stem stem, centre drill, and the sawtooth on the saw blade is regularly arranged, easy broken teeth when perforate, and perforate speed is slow.
The purpose of this utility model provides the bimetallic perforate saw that a kind of sawtooth flute profile is sharp keen, perforate speed is fast, durable.
For achieving the above object, technical solution adopted in the utility model is: a kind of metal perforate saw, and it comprises saw blade, stem stem, the centre drill of band saw tooth, and saw blade, centre drill are fixed on the stem stem, and the sawtooth on the saw blade is staggered inside and outside being at interval.
Compared with prior art, because the utility model employing flute profile is the saw blade of branch toothing, its flute profile is sharp keen, and perforate speed improves, cutting is steady, vibration is little, durable, breakage-proof, and cutting edge is not easy to come off.Especially on thin plate during perforate, be the common metal perforate cut the hole time 1/2nd.The utility model product not only can use on various electric drills, and drilling machine also can be processed, and has all size series of 14mm-170mm, applicable to multiple use.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of embodiment of the utility model bimetallic perforate saw.
Fig. 2 is the side view of bimetallic perforate saw embodiment shown in Figure 1.
Fig. 3 is the structural representation of the another kind of embodiment of the utility model bimetallic perforate saw.
Fig. 4 is the side view of bimetallic perforate saw shown in Figure 3.
Fig. 1, bimetallic perforate shown in Figure 2 are sawed by the saw blade 1 of band saw tooth 4, stem stem 2, centre drill 3 etc. and are constituted, saw blade 1 is welded on the stem stem 1, centre drill 3 is fixed on the stem stem 2 by Screw 8, sawtooth 4 is staggered inside and outside being at interval, saw blade 1 sidewall has powder outlet 5, spring 6 of suit on the centre drill 3.Iron filings are ejected by spring 6 and powder outlet 5 discharges after the perforate.
Fig. 3, shown in Figure 4 be another kind of embodiment of the present utility model, between saw blade 1 and stem stem 2, add a saw blade plate 7.Saw blade 1 is welded on the saw blade fixed head 7, and saw blade fixed head 7 is threaded with stem stem 2.After saw blade 1 wearing and tearing, can be by only changing saw blade 1 and saw blade fixed head 7, and needn't change stem stem 2.Reach the purpose of saving material.
