Abstract
A kind of chip area saw blade, comprise blade body, be arranged on blade body sawtooth circumferentially and the installing hole be arranged in blade body, chip area is formed between adjacent saw-tooth, sawtooth comprises the flank of tooth and the back of tooth, the flank of tooth of sawtooth is provided with cutter head, chip area is in " U " shape, and the end face of the back of tooth is " V " shape of outward opening; Chip area comprises the first chip removal arc, bottom land, the second chip removal arc and spigot surface successively, spigot surface be to the back of tooth tilt domatic; The distance of the first chip removal arc and installing hole is longer than the distance of bottom land and installing hole.The utility model chip area is in " U " shape, larger than the volume of common chip pocket, reduces heat in metal cutting; The back of tooth of sawtooth, in " V ", limits the maximum approach of each sawtooth, thus prevents the transition of sawtooth from using; Compared with traditional sawtooth, the utility model cutting chip removal ability is stronger, and heat in metal cutting is lower, and has anti-Transitional cut to protect, and more effectively lowly reduces noise, improves cutting quality, improves production environment.
Description
Technical field
The utility model relates to a kind of chip area saw blade.
Background technology
Conventional saw blade is when cutting material, all the time some can remain in chip area place in chip, makes blade body and be cut between material to rub, and frictional heat is constantly conducted to the back of tooth and saw blade body and produced a large amount of heat in metal cutting, and chip area volume is little, the heat of chip heat is very concentrated.Blade body can be subject to the effects such as centrifugal force, residual stress, thermal stress and cutting stress in use, longitudinal direction, transverse direction and twisting vibration can be there is, saw, while being subject to heat in metal cutting effect of stress, is subject to again complicated cutting force impact, makes the distortion of saw body generation patellate, and make saw sharply become large in producing end face run-out perpendicular to thickness direction, cause cutting instability, cut quality is deteriorated, and produces vibrating noise simultaneously, finally cause the distortion of saw body severe, even saw body body burnt.
Summary of the invention
Cut for overcoming existing chip area saw blade the shortcoming that chip removal is not smooth and frictional heating amount is large, the utility model provides a kind of novel chip area saw blade.
A kind of chip area saw blade, comprise blade body, be arranged on blade body sawtooth circumferentially and the installing hole be arranged in blade body, chip area is formed between adjacent saw-tooth, described sawtooth comprises the flank of tooth and the back of tooth, the flank of tooth of described sawtooth is provided with cutter head, described chip area is in " U " shape, and the end face of the described back of tooth is " V " shape of outward opening.
Described chip area comprises the first chip removal arc, bottom land, the second chip removal arc and spigot surface successively, described spigot surface be to the back of tooth tilt domatic, described bottom land is for facing directly.
The distance of described second chip removal arc and installing hole is shorter than the distance of the first chip removal arc and installing hole.
Feature of the present utility model and effect are: described chip area is in " U " shape, larger than the volume of common chip pocket, reduces heat in metal cutting; The back of tooth of described sawtooth, in " V ", limits the maximum approach of each sawtooth, thus prevents the Transitional cut of sawtooth; Compared with traditional sawtooth, the utility model cutting chip removal ability is stronger, and heat in metal cutting is lower, and has anti-Transitional cut to protect, and more effectively lowly reduces noise, improves cutting quality, improves production environment.

Fig. 3 is debris discharging chute structure schematic diagram of the present utility model;
Detailed description of the invention
With reference to accompanying drawing, a kind of chip area saw blade, comprise blade body 5, be arranged on blade body 5 sawtooth circumferentially and the installing hole 4 be arranged in blade body 5, chip area 2 is formed between adjacent saw-tooth, described sawtooth comprises the flank of tooth and the back of tooth 3, the flank of tooth of described sawtooth is provided with cutter head 1, and described chip area 2 is in " U " shape, and the end face of the described back of tooth 3 is " V " shape of outward opening.
Described chip area 2 comprises the first chip removal arc 2a, bottom land 2c, the second chip removal arc 2b and spigot surface 2d successively from cutter head 1 place, described spigot surface 2d be to the back of tooth 3 tilt domatic, described bottom land 2c is for facing directly.
The distance of described second chip removal arc 2b and installing hole 4 is shorter than the distance of the first chip removal arc 2a and installing hole 4.
Described spigot surface 2d tilts to the back of tooth 3, increases the appearance bits ability of chip area 2.
First chip removal arc 2a and the second chip removal arc 2b also increases the appearance bits ability of chip area 2.
The back of tooth 3 " V " shape in outward opening of described sawtooth; " V " shape back of tooth 3 top place crossing with spigot surface 2d is for limit bite projection 3a; the protruding 3a of described restriction bite limits the maximum approach of each sawtooth, thus prevent sawtooth Transitional cut, available protecting sawtooth.
The distance of described second chip removal arc 2b and installing hole 4 is shorter than the distance of the first chip removal arc 2a and installing hole 4; Bottom land 2c is for facing directly, and spigot surface 2d is domatic and tilts to the back of tooth 3, and bottom land 2c and spigot surface form a knuckle, and this all effectively increases the intensity of the back of tooth 3, can resist the impulsive force be subject to when cutting runs into hard spot; On the other hand, the tooth bottom caused because of excessive heat in metal cutting stress effectively can be avoided to crack, cause saw blade to be scrapped.
Blade body 5 is arranged on equipment mandrel by installing hole 4, and cutter head 1 is embedded on the connecting portion 3b of the back of tooth.
Content described in this description embodiment is only enumerating the way of realization that utility model is conceived; protection domain of the present utility model should not be regarded as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also comprises those skilled in the art and conceives the equivalent technologies means that can expect according to the utility model.
