Blade rotation type pipe cutting machine

Abstract

The invention discloses a blade rotation type pipe cutting machine. The pipe cutting machine comprises a wedge-shaped feed mechanism and a transmission mechanism which are installed in a protective shell, the transmission mechanism is formed by meshing a small reference circle straight tooth gear with a big reference circle straight tooth gear, a rotation power mechanism is installed on the small reference circle straight tooth gear, the wedge-shaped feed mechanism comprises a tool holder rotation base, a feed wedge-shaped block, a wedge-shaped strip, a tool holder and a cutting blade. The blade rotation type pipe cutting machine has the advantages that the mode that a machined workpiece does not move, and the blade conducts rotation cutting is adopted, a one-way radial feed mode is changed into a rotation radial feed mode, feed and cutting force is small and uniform, the structure is compact and stable, the installation space is small, the length of cutting materials is controllable, the cut surface is smooth, the action is precise, and the reciprocating cycle time is short.

Description

technical field [0001] The invention relates to hose cutting equipment, in particular to a blade rotary pipe cutting machine. Background technique [0002] At present, there are two traditional cutting methods for hose cutting in China, one is a cutting machine with a saw blade as a tool, and the other is a cutting machine with a wallpaper blade as a tool. For a saw blade cutting machine, the saw blade needs to be installed To the profile cutter, the hose to be cut is placed on the base of the profile cutter and clamped and fixed. The saw blade rotates at high speed and presses down to cut the hose with the edge of the saw blade. This cutting method will cause serious damage to the end surface of the cut hose , the end surface is uneven and accompanied by scorched phenomenon; for the wallpaper blade cutting machine, the blade needs to be installed on the cutting machine workbench, the direction of the blade must be perpendicular to the axis of the hose, and use the cylinder / ...

[0002] At present, there are two traditional cutting methods for hose cutting in China, one is a cutting machine with a saw blade as a tool, and the other is a cutting machine with a wallpaper blade as a tool. For a saw blade cutting machine, the saw blade needs to be installed To the profile cutter, the hose to be cut is placed on the base of the profile cutter and clamped and fixed. The saw blade rotates at high speed and presses down to cut the hose with the edge of the saw blade. This cutting method will cause serious damage to the end surface of the cut hose , the end surface is uneven and accompanied by scorched phenomenon; for the wallpaper blade cutting machine, the blade needs to be installed on the cutting machine workbench, the direction of the blade must be perpendicular to the axis of the hose, and use the cylinder / hydraulic cylinder on the workbench to push the blade toward the soft tube, so as to realize the cutting work of the hose. This method is not suitable for the steel wire skeleton reinforced layer hose, and the contact area of ​​the blade is large when cutting, and the service life is low, and the end surface of the hose is inclined after cutting.
