The function of clamp
● Precise positioning to ensure cutting accuracy: the primary task of the fixture is to firmly fix the workpiece (such as welded pipe and profile steel) on the predetermined cutting position. It clamps the workpiece from both sides through two collets with clamping grooves matched with the workpiece shape to ensure that the centerline of the workpiece accurately overlaps with the cutting route of the saw blade, to ensure that the notch is straight and the length is accurate.
● Firmly clamped to ensure cutting quality and service life of saw blade: huge cutting force will be generated during cutting. If the workpiece is loosened, the notch will be skew, burrs will be generated and even the saw blade will be broken. Good clamps utilize lever assisted or self-locking construction to provide a strong and stable clamping force to prevent the workpiece from sliding or vibrating. This is directly related to the smoothness of the cuts and the life of the blades.
● Follow the machine tool to realize "flying saw" dynamic cutting: in the continuous operation scene of welding pipe production line, the pipe is moving forward. The clamp here is mounted on a mobile platform called the "Chasing and Cutting Car". When cutting, the clamp clamps the pipe first, and then the whole platform moves synchronously with the production line with the clamped workpiece to complete the cutting dynamically. This is equivalent to accurately cutting a moving rope in your hand while running, and synchronous gripping without clamps is not possible.
● Auxiliary support to reduce deformation: for thin or soft pipes, workpiece bending or shaking can be easily caused by clamping at the cutting point alone. Therefore, many cold cutting saws will be equipped with rollers in front of and behind the fixture to support the workpiece together, maintain its levelness and stability in the cutting process and prevent deformation caused by dead weight from affecting the accuracy.
