A plurality of limiting grooves are arranged in the integrated stabilizing block,

the interval of every spacing groove slightly is greater than the thickness of band saw, and when the band saw normally worked, the inner wall of spacing groove did not contact with the band saw in the integrated steady piece, and when the band saw vibrated by a wide margin, its inner wall contact with the spacing groove of integrated steady piece to limit the vibration range of band saw, prevent that the band saw from splitting.

The upper stabilizer is provided with an adjusting assembly, and the adjusting assembly is used for adjusting the position of the upper stabilizer. The adjusting component comprises a lifting support adjusting cylinder. The integrated stabilizing block is arranged on the lifting bracket. The lifting support can vertically lift and is arranged on the adjusting fixing seat, the adjusting fixing seat is fixedly installed on the cutting machine frame, and the adjusting cylinder is connected with the lifting support and used for driving the adjusting cylinder to lift and further adjusting the height position of the integrated stabilizing block. The adjusting component adjusts the height position of the upper integrated stabilizing block in real time when the annular band saw is detected to vibrate (the vibration can be detected by detecting the tension fluctuation of the annular band saw or detecting the rotating speed fluctuation of the annular band saw) so as to actively reduce the amplitude of the annular band saw. When detecting the annular band saw vibration increase, steerable air cylinder drive is adjusted downwards, and air cylinder drives integrated stable piece decline to improve integrated stable piece vibration suppression effect.

Finally, it should be noted that, although the above embodiments have been described in the text and drawings of the present application, the scope of the patent protection of the present application is not limited thereby. All technical solutions which are generated by replacing or modifying the equivalent structure or the equivalent flow according to the contents described in the text and the drawings of the present application, and which are directly or indirectly implemented in other related technical fields, are included in the scope of protection of the present application.
