Abstract
The utility model discloses a saw bit capable of cutting wood with nails. The saw bit comprises a saw bit tray and saw teeth which are arranged on the outer circumference of the saw bit tray at intervals, wherein a center hole is formed in the middle of the saw bit tray. The saw teeth comprise tooth backs and alloy teeth, wherein the tooth backs are of a right trapezoid, the alloy teeth are fixedly arranged on upper ends of right angle waists of the tooth backs, and the alloy teeth are flat teeth. Trapezoid teeth made of hard alloy are adopted to enhance strength of the saw teeth, so that the saw bit is good in cutting quality, high in efficiency, and suitable for cutting objects such as the wood with the nails.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, refers in particular to a kind of saw blade of cutting belt nail timber.
Background technology
At present, the more and more aobvious variation of saw blade has a wide range of applications at aspects such as cutting stone material, timber, pottery, alloy ornament materials.Hard alloy saw blade is the most frequently used cutlery of woodwork processing, correct reasonably select hard alloy saw blade for improve the quality of products, shorten the process-cycle, the minimizing processing cost has great importance.Timber is a kind of resource that reuses, and the timber that reclaim to use is often with hard things such as nails, and general saw blade is easy to occur broken tooth and flies the tooth phenomenon when this type of timber of cutting, and cutting effect is relatively poor.
The utility model content
Be not suitable for the problem of the timber of cutting belt nail in order to solve general saw blade, the utility model proposes a kind of saw blade of cutting belt nail timber, be applicable to cut the timber with nail, cut quality is good, and efficient is high.
The technical scheme that the utility model adopts is: a kind of saw blade, comprise saw blade dish and the sawtooth that is disposed on saw blade dish excircle, the center of saw blade dish is provided with centre bore, described sawtooth comprises the back of tooth and carbide button, the described back of tooth is right-angled trapezium, the anterior angle of the back of tooth is 0 °, and described carbide button is fixedly installed on the upper end of the right angle waist of the back of tooth, and carbide button is flat tooth.
The utility model adopts the stepped tooth of being made by special carbide alloy, the sawtooth anterior angle is made as 0 to be spent and adopts flat tooth, the back of tooth is mild, the number of teeth is relatively less, strengthened the intensity of sawtooth, though descend to some extent, reduced potential safety hazards such as flying tooth on the cutting acutance, cut quality is good, is applicable to cut the timber with nail.
As preferably, the root of the described back of tooth and saw blade dish intersection are for seamlessly transitting.
As preferably, described carbide button is welded on the upper end of the right angle waist of the back of tooth.Because nail hardness in timber is high a lot of than timber, general carbide alloy sawtooth is easy to cracked as the nail in encountering timber when cutting, thereby cause saw life to reduce and have potential safety hazards such as flying tooth, so carbide button is selected special carbide alloy, the raising relative to density of its hardness is a lot, can effectively reduce probabilities cracked and the sawtooth wearing and tearing, thereby improve saw blade degree of safety and saw blade lifetime in use.
The beneficial effects of the utility model are: made up the defective that general saw blade is not suitable for cutting belt nail timber, strengthened the intensity of sawtooth, can effectively avoid sawtooth in cutting process cracked, fly the potential safety hazards such as tooth, cut quality is good.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation of carbide button of the present utility model.
In figure, 1-saw blade dish, the 2-back of tooth, 3-carbide button, 4-centre bore.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of saw blade of cutting belt nail timber, comprise that circular saw blade dish 1 and interval are evenly distributed on the sawtooth on saw blade dish 1 excircle, the home position of saw blade dish 1 has centre bore 4, and sawtooth comprises the back of tooth 2 and carbide button 3, and the back of tooth 2 is right-angled trapezium, the anterior angle of the back of tooth 2 is 0 °, carbide button 3 is welded on the upper end of the right angle waist of the back of tooth 2, and carbide button is flat tooth, and the root of the back of tooth 2 and saw blade dish intersection are for seamlessly transitting.
As shown in Figure 2, the flat tooth of carbide button 3 for being made by the W-Co kind carbide alloy, carbide button 3 is welded on the upper end of the back of tooth 2, the cross section of carbide button 3 is inverted trapezoidal, can be used for rip cutting with the multiple timber such as cork, hardwood or design of scattered small flowers and plants plate of nail, cut quality is good, and efficient is high.
Above embodiment is the preferred specific embodiment of the utility model, and common variation and replacement that those skilled in the art carry out in the technical solutions of the utility model scope are included in protection domain of the present utility model.
Claims (3)
1. the saw blade of a cutting belt nail timber, comprise saw blade dish and the sawtooth that is disposed on saw blade dish excircle, the middle part of saw blade dish is provided with centre bore, it is characterized in that: described sawtooth comprises the back of tooth and carbide button, the described back of tooth is right-angled trapezium, the anterior angle of the back of tooth is 0 °, and described carbide button is fixedly installed on the upper end of the right angle waist of the back of tooth, and carbide button is flat tooth.
