Novel circular saw web for emergency, rescue and relief

Abstract

The invention discloses a novel circular saw web for emergency, rescue and relief. The novel circular saw web for emergency, rescue and relief comprises a saw web body, wherein multiple groups of sawtooth groups are arranged on the periphery of the saw web body in an array way; a tooth back of a sawtooth of each sawtooth group is provided with a notch, so that each sawtooth is in a humping shape;multiple groups of cutter tooth groups are fixed onto each sawtooth group; the tip outer diameter values of cutter teeth in one same cutter tooth group are consistent to the thickness; the tip outer diameter values of the cutter tooth groups on each sawtooth group are diminishing equi-differently along the anti-clockwise direction; and a maximum-value cutter tooth group and a minimum-value cuttertooth group of each two adjacent sawtooth groups are arranged adjacently. The performance and the service life of the novel circular saw web for emergency, rescue and relief provided by the inventionare greatly improved; and through a unique tooth-form combination mode and a sawtooth reinforcing design, stable cutting and quick cut-off actions of a cutter can be realized under the complicated conditions of ultrahigh cutting speed and irregular-shaped material structures, and the requirement of rescue and relief operation is completely satisfied.

Description

technical field [0001] The invention relates to a novel circular saw blade for emergency, rescue and rescue. Background technique [0002] In the field of emergency rescue and rescue, when natural disasters, floods, typhoons, fires and other disasters are encountered, cutting saws are needed for operations such as protective doors and windows and anti-theft doors that need to be cut; cutting saws in the prior art All of them are equipped with grinding wheels; while the grinding wheel has a long cutting time, which leads to a long rescue time (rescue is every second counts), the cutting is not sharp and often needs to be replaced, the base strength is poor and the matrix is ​​often damaged and needs to be replaced, the cutting sparks are large, and the smoke and dust are greatly affected There are many defects such as environmental pollution, and conventional circular saw blades also have problems such as large instantaneous tool wear and poor stability. There are still many ...

[0002] In the field of emergency rescue and rescue, when natural disasters, floods, typhoons, fires and other disasters are encountered, cutting saws are needed for operations such as protective doors and windows and anti-theft doors that need to be cut; cutting saws in the prior art All of them are equipped with grinding wheels; while the grinding wheel has a long cutting time, which leads to a long rescue time (rescue is every second counts), the cutting is not sharp and often needs to be replaced, the base strength is poor and the matrix is ​​often damaged and needs to be replaced, the cutting sparks are large, and the smoke and dust are greatly affected There are many defects such as environmental pollution, and conventional circular saw blades also have problems such as large instantaneous tool wear and poor stability. There are still many deficiencies in using conventional circular saw blades to replace traditional grinding wheels.
