Abstract
The utility model relates to a circular saw blade of a sawing machine, which is provided with an auxiliary cutting edge towards the inner side of a saw body at the tooth top of a saw tooth. The saw-tooth edges and the secondary cutting edges cut alternately, so that the cutting resistance can be reduced, the saw blades are protected, the wood is prevented from being torn and the material surface is prevented from fluffing, and the sawed wood is straight and smooth. The utility model discloses the circular saw blade need not dial material, material in one piece, only needs the sharpening, has the function of saw and plane, has simplified processing technology, can practice thrift timber, improves work production efficiency.
Description
The utility model relates to a kind of saw blade of sawmilling machinery, particularly a kind ofly has a saw blade that front cutting edge has the planing function concurrently.
Usually the saw blade of using on the log splitter is using certain hour to need later on to keep in repair through beating saw body, material toggling or multiple working procedures such as binder and sharpening sawtooth, and its labour intensity is big, specification requirement is high.The saw material of saw blade evenly is to guarantee the bright and clean key factor of timber finished surface, though recent two decades has had the Planing ﹠ sawing blade appearance, played important function to improving the wood surface crudy, for indent saw body Planing ﹠ sawing blade because of sharpening after tooth top be difficult to guarantee to be positioned on the same circumference, the saw material also just is difficult to guarantee consistent; The Planing ﹠ sawing blade of plane saw body in use not only needs often to pull out material and meticulous trimmer saw material, equally also is difficult to guarantee to saw the uniformity of material.Saw blade sometimes also can be because of binding can't carry out sawing, and when the sawing hardwood, the easy rust of land is pulled out the very fast disappearance of material, because of changing the high production efficiency that influences of saw rate.
The purpose of this utility model provides a kind of improved saw blade, the function that has saw and dig, and this saw blade need not to pull out the material material all in one piece, only needs sharpening just can process the quality high product.
The utility model saw blade is to be provided with front cutting edge at the tooth top of sawtooth to saw body inboard, and front cutting edge is acute angle or right angle with the preceding cutting angle on saw body plane, and front cutting edge evenly is provided with every a tooth or number tooth.Owing to be provided with such front cutting edge, the function that its saw blade has saw and digs only needs sharpening, keeps in repair very convenient.
Fig. 1 is the structure front view of the utility model saw blade.
Fig. 2 is the A-A profile among Fig. 1.
Fig. 3 is crown structure one example of the utility model saw blade.
The utility model saw blade is made of sawtooth 1 and saw body 2 as shown in Figure 1, is provided with front cutting edge 4 from the tooth top 3 of sawtooth 1 to saw body 2 inboards, and front cutting edge 4 also can be in a side setting of saw body except as shown in Figure 2 monosymmetric setting of saw body.Front cutting edge 4 also can evenly be provided with every the number teeth except as shown in Figure 1 every a tooth is provided with.Front cutting edge 4 and saw body 2 interplanar preceding cutting angle θ also can be the right angle except as shown in Figure 2 acute angle.The relief angle β of front cutting edge 4 is an acute angle as shown in Figure 2, also can be fillet.Its sawtooth 1 of the utility model saw blade is to obtain the profile of tooth of common saw blade by the round steel sheet through tooth punching, for example: directly carry on the back tooth, cut back of the body tooth, protruding back of the body tooth, triangle bevel grinding tooth, straight anticline roll flute or cut anticline roll flute etc.The sawtooth of the utility model saw blade and saw body size can be chosen by the basic size specification of existing saw blade.For example: the saw blade of Φ 400mm, thickness can be selected 1.2mm, 1.4mm or 1.6mm for use, the number of teeth 70 or 80.When for example selecting the thickness 1.4mm number of teeth 80, all the other dimensional parameters are: each 40 in saw body both sides of front cutting edges, the high 0.7mm of front cutting edge, wide 3mm, long 130mm, 80 ° at preceding cutting angle, 45 ° of relief angles.Front cutting edge 4 can and be sawed as one by the punch forming of round steel sheet, comes through the machining sword again; Weld again or be adhesively fixed on after front cutting edge 4 also can process separately as shown in Figure 2 on the saw body 2.Front cutting edge 4 is saw body 2 inboard settings the from tooth top 3 along throat of tooth alignment as shown in Figure 1, and also front cutting edge 4 departs from throat of tooth line 5 to saw body 2 inboard settings from tooth top 3 as shown in Figure 3.Front cutting edge 4 is when throat of tooth alignment saw body 2 inboards are provided with the utility model as shown in Figure 1, and also just forming as shown in Figure 3 behind sharpening repeatedly, throat of tooth line 5 departs from front cutting edge 4 certain angles.Because this saw blade of processing need not material toggling, binder, material all in one piece manufacturing procedure, bring convenience not only for processing and maintenance, and can suitably improve the hardness of saw blade, to increase the wearability of land, front cutting edge 4 also has the effect of reinforcement, can increase the rigidity of saw body outer rim, the life-span of improving saw blade.
As shown in Figure 1, the sawtooth place 1A thin by sawtooth 1 saws out earlier narrow swage set to the utility model saw blade when sawing timber, carries out secondary cutting again by the band front cutting edge thicker sawtooth 1B in place then.Because timber is a kind of rubber-like material; when the land sawing is passed through; the timber of swage set wall both sides can be to swage set both sides extruding, after land passes through, are cut by the second front cutting edge during timber resilience that is extruded; repeatedly alternately cutting of front cutting edge and land like this; can reduce cutting resistance, be difficult for binding, can protect saw blade; prevent that timber from tearing and charge level fluffs, the timber that saw is come out is not only straight but also bright and clean.The utility model saw blade unites two into one the two procedures of saw and plane, has simplified processing technology, not only saves timber, has also improved labor productivity.
