Saw cutting machine for special pipes

Abstract

The invention discloses a saw cutting machine for special pipes. The saw cutting machine comprises a machine base, a feeding clamp assembly, a saw cutting device and a discharging clamp assembly. The saw cutting device is installed on the machine base. The feeding clamp assembly is fixed to the upstream side of the saw cutting device and comprises an arc-shaped chute base, a rotating base, a first clamp half body, a second clamp half body, a clamping power device and a locking device, wherein the arc-shaped chute base is fixed to the machine base, the rotating base is installed on the arc-shaped chute base and locked by the locking device, at least one of the first clamp half body and the second clamp half body is installed on the rotating base in a sliding mode, and the clamping power device is fixed to the rotating base to drive the first clamp half body or / and the second clamp half body to get close to each other or get away from each other in a sliding mode. The discharging clamp assembly is installed on the downstream side of the saw cutting device and driven by a discharging power device to slide. The saw cutting machine can clamp the pipes optionally in different directions, make cross sections of cut pipes neat, improve cutting quality and prevent damage to the surfaces of the pipes.

Description

technical field [0001] The invention relates to a sawing machine, in particular to a special-shaped pipe sawing machine. Background technique [0002] A sawing machine is a device that uses a rapidly rotating saw blade to cut pipes online. When the saw blade is cutting, the pipe is clamped by the feed clamp assembly, and the cut pipe also needs the discharge clamp assembly to clamp the pipe and feed it. The current clamps generally clamp the pipe from the left and right sides of the pipe. However, due to the variety of cross-sectional shapes of the pipe, after the pipe of some shapes is formed by the upstream machine, the clamped parts on the left and right sides of the pipe It has multiple flutes or other shapes that are not suitable for left and right clamping. At this time, if the current existing clamps are still used to clamp, it is easy to cause damage to the surface of the pipe, and the phenomenon of clamping slip may also occur, resulting in uneven cross-sections a...

The current clamps generally clamp the pipe from the left and right sides of the pipe. However, due to the variety of cross-sectional shapes of the pipe, after the pipe of some shapes is formed by the upstream machine, the clamped parts on the left and right sides of the pipe With multiple flutes or other shapes that are not suitable for left and right clamping

At this time, if the current existing clamps are still used to clamp, it is easy to cause damage to the surface of the pipe, and there may also be a phenomenon of clamping slippage, resulting in uneven cross-sections and affecting the cutting quality
