Problems solved by technology

This method of filing tends to rapidly raise the temperature of the working side of the file to above the martensitic transformation temperature (230°C), which will cause the working side of the file to anneal and lose hardness and shorten the service life

Embodiment Construction

[0019] The method for prolonging the service life of a fitter's tool is characterized in that when using the fitter's tool for work, the two sides of the fitter's tool are used alternately.

[0020] The fitter tool is a saw blade, which is sawed with one side of the saw blade, and the other side of the saw blade is not sawed, that is, the saw blade and the surface of the object to be sawed, so that the two sides of the saw blade are alternately performed, and the saw blade swings like a V during sawing. It is also called V-shaped sawing method.

[0021] Said sawing is full-tooth sawing.

[0022] The swing angle of the saw blade is 0.5 to 1°.

[0023] The fitter's tool is a file. When filing, use one side of the file to make 3 to 5 cuts, and then use the wrong side to make another 3 to 5 cuts. The two sides of the file work alternately.

Abstract

The invention discloses a method capable of prolonging service life of a fitter's tool. The method is characterized by including: alternately using two side faces of the fitter's tool when the fitter's tool is used for working. Compared with the prior art, the sawing method has the advantages that one side not being used for sawing is equivalent to normalizing, so that heat generated by friction can be reduced, and existence of a martensite matrix of a saw blade is ensured (in other words, hardness of the saw blade is ensured unchanged constantly or precipitation time of middle carbon of martensite is prolonged); saw dust is enabled to be crisp and prone to shedding, and a cut material is enabled to be crisp, so that cutting is better facilitated. By the filing method, one side not being used for filing is equivalent to normalizing, so that heat generated by friction can be reduced, and existence of a martensite matrix of saw teeth is ensured (in other words, hardness of the saw teeth is ensured unchanged constantly or precipitation time of middle carbon of martensite is prolonged); file dust is enabled to be crisp and prone to shedding, and a filed material is enabled to be crisp, so that filing is better facilitated.

Description

technical field [0001] The invention relates to a method for using a tool, in particular to a method for prolonging the service life of a fitter's tool. Background technique [0002] As we all know, the currently accepted correct sawing method is that the saw blade is perpendicular to the plane of the object to be sawed (the effect is that the saw blade and both sides of the saw seam are in contact and friction during sawing), and it is recognized that 2 / 3 of the full length of the saw blade works. This sawing operation method is not conducive to the diffusion of the heat generated by the saw blade during sawing, and it is easy to increase the temperature of the saw blade to above the martensitic transformation temperature (230 ° C) in a short time, so that the saw blade loses its hardness during annealing and shortens its service life. . When filing, use one side of the file until it becomes unusable, then use the other side. This filing method is easy to rapidly increase...
