Description

Economize on electricity saw blade before crown inclines

(1) technical field: the utility model relates to and is a kind ofly used for sawing the smooth energy-conservation saw in the sawing face of separating timber or similar wood material.

(2) background technology: at present for sawing the saw blade separating timber or similar wood material, sawing face is smooth not bright and clean, often with other if the way of sanding, planing is to these sawing face reprocessing, have in order to reach sawing face zero diopter, adopt high-revolving alloy hacksaw, this cost is higher, and energy consumption is also larger.

(3) summary of the invention: task of the present utility model improves existing saw blade, very smooth bright and clean, the saving processing cost in the sawing face that saw can be made to go out, and economize energy, and the price of saw blade is also enough cheap.

Task of the present utility model completes as follows: carry out chamfered to the part sawtooth of saw blade, sawtooth is made not only to see it is sharp (original shape) in front, and side sees it is also sharp (certainly should rotate to certain position to each sawtooth of annular saw), such saw sawtooth when moving equals to form the sharp keen knife edge, aim at front sawing, thus saw out bright and clean sawing face, and economize energy, certain sawtooth also by usual mode separately, and should form swage set.But saw reserve part does not have the tooth of chamfered, and this sawtooth is among swage set, and this synchronously can destroy the wooden of the saw cut of chamfered.Occupy sawtooth among swage set, tooth angle changes into by 90 ° and is greater than 90 °, is obtuse angle, before crown is inclined, can reach the effect that sawtooth shovels timber and digs like this.And all sawtooth change into before crown is tilted to equally.

Traditional saw blade, front is seen as sharp sawtooth one by one, but side sees above sawtooth it is a horizontal line, in its course of work, sharp keen dissection is not played to timber, just the wood-fibred on swage set " is left behind ", this also can pull the wood-fibred outside swage set, destroys, therefore sawing surface is bright and clean not, and the resistance of motion of saw also large, energy consumption is large; For timber during sharp-pointed its motion of the utility model sawtooth is just like the dissection as point of a knife, less to wood-fibred pulling force, therefore can not destroy the wood-fibred outside swage set, and therefore sawing face is brighter and cleaner, and advance resistance is also little, very energy-conservation.The improvement tradition sawtooth retained, also synchronously can destroy wooden, also lower saw advance resistance.Tradition sawtooth belongs to timber effect and draws the form of scraping, and the sawtooth crown increasing tooth angle forward, and act as shovel, plane form to timber, apparent the latter's effect differs widely with the former.All sawtooth all turn forward, and make saw greatly improve wedging timber, sawing effect forward reduces energy consumption.

The technical solution adopted in the utility model is the electric plectane saw blade or belt straight blade or hand straight blade that are made up of saw plate and sawtooth.

Electricity plectane saw blade, is characterized in that: its swage set both sides sawtooth is seen in the side of saw, crown is tip shape, have sawtooth, and its sawtooth tooth angle is obtuse angle, saws each sawtooth crown all forward among swage set.

Belt straight blade, is characterized in that: its swage set both sides sawtooth is seen in the side of saw, crown is tip shape, have sawtooth, and its tooth angle is obtuse angle, saws each sawtooth crown all forward among swage set.

Hand straight blade, is characterized in that: its swage set both sides sawtooth is seen in the side of saw blade, crown is tip shape, have sawtooth, and its tooth angle is obtuse angle, saws each sawtooth crown all forward among swage set.

(4) accompanying drawing illustrates: the utility model is described further by reference to the accompanying drawings, and accompanying drawing is the schematic diagram of electric circular saw sheet and rip (belt saw, hand rip) sheet.

Fig. 1 is front view, and Fig. 2 is side view.Fig. 1 [1], Fig. 2 [1] are sawtooth point, and before crown is tilted to, Fig. 1 [2], Fig. 2 [2] are saw plate, and Fig. 1 [3] is sawtooth flour milling.Fig. 1 [4] and Fig. 2 [3] for tooth angle be obtuse angle crown forward improvement tradition sawtooth, Fig. 2 [4] swage set.Fig. 1 [5] is lower end, crown both sides line, and Fig. 1 [6] is tooth angle.Fig. 1 [7] saws the center of circle, and circle 1 [8] saw radius, connects the center of circle, crown, before obvious crown is tilted to.

Fig. 3 is saw front view, Fig. 4 is side view, Fig. 3 [1], Fig. 4 [1] are crown, before crown is tilted to, Fig. 3 [2] and Fig. 4 [2] is saw plate, Fig. 3 [3] is sawtooth flour milling, and Fig. 3 [4] and Fig. 4 [3] improves the crown improvement tradition sawtooth forward that tooth angle is obtuse angle, and Fig. 4 [4] is swage set, Fig. 3 [5] improves lower end, sawtooth crown both sides line, and Fig. 3 [6] improves sawtooth tooth angle.Fig. 3 [7] crown to saw edges of boards vertical line, before obvious crown is tilted to.

(5) detailed description of the invention: embodiment: (sawtooth of saw is not also separately named to both sides and do not open swage set with the saw blade also not opening swage set.Namely each sawtooth is swage set between two gang saw teeth after respectively separating to saw both sides by the usual practice).Sawtooth front to actinal surface polish sawtooth flour milling figure, make sawtooth front to one-tenth knife-like, the sawtooth of chamfered becomes one " pocket knife " of one side mill one by one, crown becomes point of a knife, the face of its polishing of adjacent chamfering sawtooth is respectively in the both sides of saw, after sawtooth is all polished, and then point swage set, two often adjacent sawtooth are broken to different directions, adjacent chamfering sawtooth divides to saw both sides by the general swage set practice, a traditional sawtooth is remained with among adjacent chamfering sawtooth, such " edge of a knife " that can ensure sawtooth wherein, to sawtooth third side to wood-fibred sawing and get.Crown is at the ragged edge of saw, sawtooth other parts must not exceed crown, in order to avoid the resistance that the sawing face of destruction and increase saw advance, on saw, the crown on both sides is respectively in the same plane on both sides, saw work time, sharp crown as point of a knife to the quick sawing of timber, " edge of a knife " of sawtooth is also the wood-fibred sawing in swage set direction, saw night is got, reaches quite bright and clean sawing face, and saved the energy.Break swage set and notice that sawtooth chamfering is within swage set, each traditional sawtooth is between adjacent chamfered teeth, then traditional sawtooth tooth angle is changed into obtuse angle by right angle, before crown is inclined to, therefore reach and had the action effect of shovel and plane to timber, lower resistance, obviously saved the energy, chamfered teeth oppositely should be broken to flour milling, guarantees the serrated knife mouth knife edge outside.Saw before all sawtooth crowns are all tilted to.

Electricity plectane saw blade, belt straight blade, hand straight blade: by embodiment to part sawtooth chamfered, reserve part tradition sawtooth also changes large tooth angle, and crown forward.By routine way, break into swage set and finished product.Saw before all sawtooth crowns are all tilted to.
