Abstract

PURPOSE:To prevent generation of vibration during cutting operation by eliminating the idle play between an arm and the driving part for the arm during cutting operation and eliminating the variation of the cutting-in amount by maintaining the feed speed of a blade at a constant value. CONSTITUTION:The deflection of position of a slide block 18 from the position of a receiving plate 20 due to the turning of an arm 12 is absorbed by the rolling of a roller 21. The upward shift of the arm 12 during cutting is restricted by the slide block 18, and since the force larger than the cutting load play is always operated upwardly by a hydraulic cylinder 14, the idle between the arm 12 and the driving part is perfectly eliminated, and the generation of vibration is prevented.

When cutting materials, especially when cutting pipe materials with low rigidity, it is required to suppress the generation of vibration during cutting as much as possible in order to obtain a good finish at the cut end. As shown in FIG. 1, a conventional cutting device has a blade feeding device that has a blade 1 in the center and a proximal end of an arm 2 supported by its rotary drive device f', which is pivotally supported on a base frame 3. The other end of the arm 2 is connected to a piston/4a of a hydraulic cylinder 4 attached to the side of the base frame 3 via a connecting pin 5, and the hydraulic pressure of the hydraulic cylinder 4 is controlled by a flow rate control valve 6 to operate the cylinder 4a. By raising the arm 2), the blade 1' (r) is moved toward the workpiece W fixed by a clamping device (not shown) to obtain the feed of the blade 1, and after the cutting is completed, the arm 2 is By retracting the arm 4a, the blade 1 is moved in the opposite direction to the above-mentioned direction for quick return.However, in this type of blade feeding device, the arm 2
and the piston 4ai, a connecting pier 5 rotatably connected to each other.
There are inevitably gaps in the parts, and thus, conventionally, the depth of cut of the blade 1 during cutting tends to fluctuate, causing load fluctuations and vibrations.
