| 小编说：旋切机正确安装旋刀，应保证满足两个条件！ Small editor said: rotary cutting machine correct installation of rotary knife, should ensure that meet the two conditions! 1、应使旋刀两端在同一高度上，而且使旋刀安装高度等于旋切工艺中规定的h值。具体方法如下： 1, the two ends of the rotary cutter should be on the same height, and the installation height of the rotary cutter is equal to the H value stipulated in the rotary cutting process. Specific methods are as follows: （1）将刀放入刀槽内，先拧上两端夹紧螺母各一个。 (1) put the knife into the knife slot, first screw the nut at each end. （2）用高度计或相当于卡轴中心线高度的等高器作标准，通过调节支承螺钉，使两瑞刀高等于旋切工艺中的规定的h值（无防弯压辊的旋切机，调节旋刀中部的支承螺钉，使刀刃中部比两端高0.1—0.2毫米，以适应木段旋小时，由于刀床挤压木段产生弯曲变形而引起单板厚薄不匀的现象。有防弯压辊的旋切机，刀刃中部不必提高，并紧固所有螺母。 (2) altimeter or equivalent shaft centerline height and a high standard device, by adjusting the support screw, the two Swiss knife high rotary cutting process is equal to the specified H value (no anti bending roller rotary cutting machine, rotary cutter adjusting central support screw, the blade ends are higher than the middle of 0.1 - 0.2 mm, in order to adapt to the wood rotary hour, as the knife bed squeezing wood bending deformation caused by single plate uneven phenomenon. There is no need to increase the middle part of the blade, and fasten all nuts. 2、应使后角变化范围与旋切木段直径的范围相适应，具体方法如下： 2, should be after the angle range and peeling block diameter range to adapt to the specific methods are as follows: （1）首先将刀床退至相当于旋切木段的最大直径处（或规定的某一位置），用测后角仪测定其初后角。若初后角与旋切工艺中规定的初后角不相符合，则通过调节装置调节偏心盘，使初后角等于旋切工艺中规定的数值。 (1) the maximum diameter of the knife bed back to the equivalent of peeler section (a position or specified), measured by the angle measuring instrument and the initial angle. If the initial angle is not consistent with the initial and posterior angle stipulated in the rotary cutting process, the eccentric disk is adjusted by adjusting device so that the initial angle is equal to the value specified in the rotary cutting process. （2）将刀床往前开至相当于木芯直径位置（或规定的某一位罝），再测定其终后角，并观察后角变化范围与木段直径是否相适应。 (2) the knife bed drive to a wooden core diameter position (a placement or specified), to determine the final angle, and the range of observation angle and log diameter is compatible. （3）若初后角符合要求而终后角不符合旋切工艺要求，不可通过调节装置调节偏心盘来调整终后角。因为调整了偏心盘，终后角虽然符合要求而初后角却又不符合要求了。此时可调节辅助滑道的倾斜角。终后角太小,可减小倾斜角。终后角满足要求后，则退回初始位贺，检查初后角。 (3) if the back angle meets the requirements, the final angle does not meet the requirements of the rotary cutting process, and the end angle can not be adjusted by adjusting the eccentric disk. Because the adjustment of the eccentric disc, the end angle is consistent with the requirements, but the initial angle does not meet the requirements. The angle of the auxiliary slideway can be adjusted at this time. The rear end angle is too small to reduce the inclination angle. When the posterior horn meets the requirements, the initial position should be returned and the posterior angle should be checked. 在没有测后角仪的条件下，换好刀后，凭经验调整好后角，开车旋切时，要注意整个旋切过程进刀是否平稳。观察刀刃与木段表面摩擦部分的明亮宽度，即可判定后角调得是否适当。一般明亮部分的宽度约3—4毫米时，说明后角的大小和后角变化范围与木段直径范围基本上是适应的。 In the condition of no measuring angle instrument, after changing the knife, adjusting the back angle with experience, driving the rotary cutting, attention should be paid to whether the feed is stable in the whole rotary cutting process. Observe the bright width of the friction part between the blade and the wood segment, and determine whether the rear angle is properly adjusted. When the width of the bright part is about 3 - 4 mm, the size of the back angle and the range of the back angle are basically adapted to the diameter range of the wood section. |
