锯片结构图齿形、修磨及应用

  安全使用锯片

  1、 所配设备应具备安全保护装置,如:防护罩,断电刹车,过载保护等。

  Applied machine shall be equipped with safety devices, such as protective cover, power-off brake and overload protector.

  2、 检查锯片有无损坏,齿型是否完整,锯板是否平整光洁,以及有无其他异常现象,以确保使用安全。

  Check if the saw blade is scratched, if the edge is complete and if the blade sheet is flat and clean to ensure the safe status.

  3、 确保机器状态良好,主轴无变形,无径跳,轴径公差为h7。保证锯片回转方向与机器主轴回转方向一致。

  Ensure the sound condition of the machine including but not limited to no transformed bearing, no track jump and the tolerance is h7. Reversing direction of blade shall be the same with that of main bearing.

  4、 法兰盘内径与锯片内径一致,外径应不小于锯片外径的1/3,并确认其表面平整光洁,无变形,无端跳。保证锯片内径与机器轴径之间无过大间隙,安装好法兰盘,装好定位销,拧紧螺母。

  Internal diameter of Flange Plate should be the same with that of the blade. External diameter should be no smaller than 1/3 of external diameter of the small blade. The surface should be flat and clean without transformation and end jump. Avoid too big gap between the blade and the bearing in terms of internal diameter. After installation of Flange Plate, set up the positioning pin and fasten the nut.

  5、 工作时,发现声音和振动异常、切割面粗糙、或产生异味时,必须立即终止作业,及时检查,排除故障以免发生意外事故。

  If any noise, vibration or unsmooth surface or bad smell is detected, please stop the operation immediately and a check should be conducted shortly to avoid any possible accident.

  硬质合金圆锯片的修磨

  当锯片不再锋利,切断横截面粗糙,必须对锯片进行修磨,否则对切割效果有很大的影响,导致锯片使用寿命缩短,有以下情况须进行修磨更换处理:

  1:使用锯片的机器耗能显著增加

  2:加工材料时,有明显崩裂现象

  3:合金刀头的刃口磨损达到0.02MM

  锯片的修磨,应到专业的修磨机器或公司进行修磨,确保锯片长期高效使用。
