Abstract
The invention relates to a radiation effect improving based saw web improvement structure. The structure comprises a disc carrier and saw teeth arranged on the outer circumference of the disc carrier. A mounting hole is formed in the center of the disc carrier, at least two slits are formed in the disc carrier, the side walls of the slits and the disc carrier surface are in smooth transition, the axial widths of the slits are increased gradually from the slit centers to the disc carrier surface, and the slit side walls are sunken to form a plurality of grooves. By means of the structure, the slits are formed, so that the defect of the poor radiation property of saw webs is overcome; thanks to the grooves, the radiation efficiency is further improved; due to the improvement of the radiation efficiency, the resistance to saw webs during rotation is small, the rotation frequency is improved, and the use performance and the service life of saw webs are increased by overcoming the defect of the poor radiation property of saw webs.
Description
Technical field
The present invention relates to work piece cut mechanical field, particularly, relating to the saw blade modified node method based on improving radiating effect.
Background technology
At furniture production field, committed step to the processing of workpiece, especially to the cutting processing of wooden boards, sawing generally applies to the cutting technique of sheet material as a kind of convenient and simple technique, therefore incisory saw blade is applied in Furniture manufacturing industry widely, the quality of saw blade quality directly has influence on the quality of institute's section of converted timber.The problem that saw blade ubiquity thermal diffusivity used in furniture production industry is at present poor, saw blade is under High Rotation Speed, and produce high-speed friction with cut sheet material, making easily to produce heat in the use procedure of saw blade can not distribute, and whole saw blade is hot, heat can not distribute and make saw blade inside gather heat, make saw blade be subject to uneven heat in metal cutting, the phenomenon of burning saw can occur, the serviceability of saw blade is reduced, not only have influence on production efficiency, but also have influence on machining accuracy.
Summary of the invention
Technical problem to be solved by this invention is to provide the saw blade modified node method based on improving radiating effect, to overcome the problem of existing saw blade poor radiation.
The present invention's adopted technical scheme that solves the problem is: based on the saw blade modified node method improving radiating effect, comprise disc carrier, sawtooth, disc carrier center that disc carrier outer circumference surface is arranged be provided with installing hole, disc carrier offers at least 2 slits, slit sidewall and disc carrier surface rounding off, the axial slit Kuan Youfeng center of slit in the trend increased gradually to disc carrier surface, slit sidewall caves inward and is formed with some grooves.On the one hand, saw blade in the course of the work can High Rotation Speed, the high-speed rotary change of team produces heat, on the other hand, sawtooth and the sheet material that will cut produce and rub, the heat that further generation is a large amount of, existing saw blade does not mostly arrange heat abstractor, therefore the heat that sawtooth produces in the course of the work can not be discharged in time, saw blade inside is made to gather a large amount of heats, gathering of heat can cause saw blade to produce thermal strain on microcosmic, this thermal strain can cause the performance of saw blade to change, the performance change of saw blade makes the cutting performance of saw blade be deteriorated, not only influence zone machining accuracy, and can production efficiency be had influence on, the present invention arranges slit on disc carrier, the axial slit of slit on disc carrier is wide is 1 ~ 2mm, and the one side that arranges of slit decreases the area producing heat, provides a passage that can dispel the heat on the other hand, the heat that saw blade is produced can be distributed, and reduces the thermal strain of saw blade, the axial slit Kuan Youfeng center of slit is the trend increased gradually to disc carrier surface, stitch the wide less structure of wide employing seam center seam, make taking up room of whole slit little, ensure that the structural stability of whole saw blade, make saw blade can not reduce the stress of saw blade because being provided with slit, adopting seam wide is the structure increased gradually to disc carrier surface, increase the space of heat radiation, increase the efficiency of slit heat radiation, at slit sidewall, groove is set, further increase heat-dissipating space, improve radiating efficiency, and the surface of the sidewall of slit and disc carrier is rounding off, reduce the resistance of hot-fluid during heat radiation, heat can be distributed along round and smooth curved surface smoothly, so, instant invention overcomes the problem of saw blade poor radiation.
Further, groove is curved-surface structure.Curved-surface structure makes the inner space of groove comparatively large, and curved-surface structure seamlessly transits, and decreases the resistance in radiation processes, resistance can not be increased because of the setting of groove, therefore the curved-surface structure of groove makes slit space increase, resistance can not produce significant change, improves radiating efficiency.
Further, connected by level and smooth convex surface between adjacent grooves.The connected mode of level and smooth convex surface has laughed at the resistance of recess sidewall further, plays guide effect to hot-fluid simultaneously, accelerates distributing of heat, improves radiating efficiency.
Further, the radial slot of slit is wide increases to sawtooth one end gradually from installing hole one end.The increase of the wide radius along with disc carrier of radial slot and increasing accordingly, the trend increased is wide consistent with the axial slit of slit on disc carrier, radial slot is wide is 1 ~ 2mm, and this structure, in the constitutionally stable situation ensureing whole saw blade, can increase heat-dissipating space to greatest extent.
Further, the cut surface of sawtooth is plane, and the back side of cut surface is curved surface, in smoothing junction between cut surface and the back side.Cut surface is that plane is convenient to cutting, and the cut surface back side is that curved surface makes the structure of sawtooth more stable, and curved surface connects and compared with the resistance of small saw blade under High Rotation Speed, can improve the frequency rotated.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by arranging slit, overcomes the problem of saw blade poor radiation.
2, the setting of groove of the present invention further increasing radiating efficiency.
3, the invention enables saw blade resistance in rotary course less, improve the frequency of rotation.
4, the present invention improves cutting performance and service life by the problem overcoming saw blade poor radiation.
