Energy-saving pipe cutting machine and its toothless cutting device

Abstract

The invention relates to the field of cold working mechanical equipment, in particular to a pipe cutting device. An energy-saving pipe cutting machine comprises a pipe clamping device on a work table. One end of the work table is provided with a toothless cutting device for cutting pipes, and the work table and the toothless cutting device are connected through a bearing. A rotary shaft of a motor is connected with the toothless cutting device. An electric control system connected with the motor comprises a frequency conversion circuit, the frequency conversion circuit outputs a group of high-frequency work power supplies and a group of low-frequency standby power supplies to the motor, and the work power supplies and the standby power supplies are switched through switches in a stepless mode. The toothless cutting device comprises a wheel and a cutter moving radially under the effect of centrifugal force. The motor of the energy-saving pipe cutting machine works under the control of the frequency conversion circuit and does not rotate when cutting movement is not conducted, and energy consumption is small. Debris is not caused during pipe cutting by using the toothless cutting device, the debris is not required to be washed in follow-up procedures, production efficiency is improved, and production cost is saved.

Description

technical field [0001] The invention relates to the field of cold working mechanical equipment, in particular to a pipe material cutting equipment. Background technique [0002] When pipes such as air conditioner compressor pipes are cut to length, the pipe cutting equipment in the prior art uses grinding wheels or saw blades to cut the pipes. There are sharp edges and debris on the cut surface of the pipe after cutting, and it needs to go through the cleaning process before it can enter the next process. [0003] Such as CN1165726 No. Chinese patent discloses a kind of cutting machine, comprises reducer and gearbox on the workbench, and the front of the gearbox is provided with chuck; , Install the grinding wheel grease sheet on the grinding head. The motor of this type of pipe cutting machine continues to run at high speed without load, which consumes a lot of power. The cutting of the pipe by the grinding wheel causes debris to splash, and the cut pipe needs to go thro...
