Abstract

The present invention relates to a cutting method of the saw blade, in which the cutting is realized by repetitively generating localized high temperature to soften the object and then scraping away the softened part by a gear shot. The characteristic of the cutting method lies in the steps of the cutting which include: A) fixing a round metal cutting saw blade to the motor shaft through a lashing eye (1) in the motor shaft; B) turning on the motor, the edge of the round metal saw blade acutely abrading against the cut part of the metal pipe fitting, the process of which generates abundant heat at the cut part, the heat being concentrated in a small area at the cut part and unable to get dissipated in time, so the cut part of the metal pipe fitting softening or melting with the rising of the metal temperature; C) a slot (2) arranged on the edge of the round metal saw blade scraping away the softened part of the metal pipe fitting; D) repeating step C until the cutting of the metal pipe fitting is finished.

Description

A kind of cutting method of saw blade

Technical field

The present invention relates to the method for saw blade cutting, be specially and make the local high temperature that produces make that object is softening will to be softened part by teeth groove again and scrape off the cutting method of a kind of saw blade that realization is so repeatedly cut.

Background technology

Present metal tube cutting blade is divided into two kinds of methods: the one, and adopt the cutting blade of emery disc form to cut, it is characterized in that this cutting blade material is an emery wheel, rotate at a high speed and be cut fitting to fitting and acutely rub by driven by motor emery disc form cutting blade, metal tube and emery disc form cutting blade are in friction, a large amount of wearing and tearing all appear in both contact-making surfaces, thereby realize the disconnected tube wall that cuts metal tube, its friction cuttings principle is that sand grains hardness in the emery disc form cutting blade is greater than being cut metal, but between the sand grains at the bottom of the bonding precision, such product shortcoming just is the high wear rate of cutting blade, the cutting blade replacement cycle is short, if the construction cost height is more low at higher its cutting efficiency of metal tube of hardness ratio.Another cutting method is: utilize the edge of cutting blade to be sawtooth pattern, rotate at a high speed and be cut pipe fitting by driven by motor sawtooth pattern cutting blade firmly to hard cutting, sawtooth quick wearing and tearing passivation in cutting process need be polished one by one to sawtooth and be kept sharp, but the cutting blade loss is rapid, the process of sawtooth polishing extremely bothers, the polishing of sawtooth also makes cutting operation efficient reduce, section after this method cutting is uneven, also very difficult in the cutting operation to being cut fixing of pipe fitting, occur being cut the situation that pipe fitting is beated easily, the cutting blade edge weares and teares by a small margin also can cause the reduction of cutting efficiency.

Summary of the invention

The objective of the invention is to very provides a kind of rational in infrastructure to above technical problem, long service life, the cutting method that cutting efficiency is high.

Concrete technical scheme of the present invention is as follows:

A kind of cutting method of saw blade is characterized in that: its cutting method comprises following method step:

A) with a kind of discoidal Metal Cutting sheet by the motor shaft fixing hole and be fixed on the motor shaft;

B) starter motor, the part that is cut of the edge of discoidal Metal Cutting sheet and metal tube acutely rubs, the position that is cut can produce a large amount of heat when friction, heat concentrates on the very little scope of cutting part and can not in time dispel the heat, material deliquescing or thawing after the metal temperature of the metal tube that is cut rises;

C) part that is cut metal tube after the bar of discoidal Metal Cutting sheet edge setting seam will soften scrapes;

D) the C step of carrying out is repeatedly finished the cutting that is cut metal tube.

The material that saw blade adopts is a metal, and cutting method will be softened part by teeth groove again for local generation high temperature in cutting process makes object soften and be scraped off the saw blade of realization cutting so repeatedly.

Saw blade is owing to the minimizing of the number of teeth, and frictional distance increases, and teeth groove can arrive and be cut the place when position that is cut reached more softening, can scrape off being cut the position easily, reduce load, reduce noise, also reduce self wearing and tearing of saw blade, increased the speed of feed.

The degree of depth of teeth groove has reduced, and can reduce the vibrations of tooth and saw blade, can stop the generation of tooth, has increased security.

Technique effect of the present invention shows: in the method, and the minimizing of the saw blade number of teeth, frictional distance increases, can scrape off being cut the position easily, reduce load, reduce noise, also reduced self wearing and tearing of saw blade, increase the speed of feed, the degree of depth of teeth groove has reduced, and can reduce the vibrations of tooth and saw blade, can stop the generation of tooth, increased security, the consumption of saw blade itself has reduced, and has also just reduced the cost of saw blade.

The specific embodiment

The invention will be further described below in conjunction with the specific embodiment and Figure of description

Embodiment:

E) with a kind of discoidal Metal Cutting sheet by motor shaft fixing hole 1 and be fixed on the motor shaft;

F) starter motor, the part that is cut of the edge of discoidal Metal Cutting sheet and metal tube acutely rubs, the position that is cut can produce a large amount of heat when friction, heat concentrates on the very little scope of cutting part and can not in time dispel the heat, material deliquescing or thawing after the metal temperature of the metal tube that is cut rises;

G) part that is cut metal tube after the bar of discoidal Metal Cutting sheet edge setting seam 2 will soften scrapes;

H) the C step of carrying out is repeatedly finished the cutting that is cut metal tube.

Claims

1. the cutting method of a saw blade, it is characterized in that: its cutting method comprises following method step:

A) with a kind of discoidal Metal Cutting sheet by motor shaft fixing hole (1) and be fixed on the motor shaft;

C) part that is cut metal tube after the bar seam (2) of discoidal Metal Cutting sheet edge setting will soften scrapes;

2. cutting method according to claim 1 is characterized in that: the material that saw blade adopts is a metal, and cutting method will be softened part by teeth groove again for local generation high temperature in cutting process makes object soften and be scraped off the saw blade of realization cutting so repeatedly.
