Abstract
The invention relates to a cutting tool for section materials such as steel pipes, round steel and the like, in particular to a high-efficiency cold saw circular saw blade. The method is characterized in that: this circular saw blade 8 does not have inflation groove is equipped with tool bit 5 and amortization line 4 in 8 outside sides of circular saw blade, amortization line 4 runs through for 8 two sides of circular saw blade, radial centripetal rectangular structure, there are many to distribute on circular saw blade 8 in circumference, the radial range that amortization line 4 set up is outside 8 radial 2/3 of circular saw blade, inwards be greater than the circumference scope 3 between 10mm for apart from the tooth bottom 9, the circumference scope that every amortization line set up, radial centripetal ray contained angle B1 is within 2 in the amortization line region that 10 fan-shaped and circumference scope coincidence formed at circular saw blade 8. Through the arrangement, the flatness of the section of the cut workpiece can be good, the lines of each cut are clear, the friction between the side surface of the cutter head and the cutting gap is eliminated, the power loss of the saw is reduced, the heat generated by the workpiece and the saw blade is reduced, and the saw blade can keep the requirement of the optimal cutting performance for a long time.
Description
Technical Field
The invention relates to a cutting tool for section materials such as steel pipes, round steel and the like, in particular to a high-efficiency cold saw circular saw blade.
Technical Field
The cold saw circular saw blade is a cutter for cutting various steel materials. The existing cold saw circular saw blade has small diameter and large cutting force, if a silencing line and an expansion groove are arranged in the same mode as an aluminum saw, the cold saw circular saw blade is easy to twist and break teeth during cutting, and a base body is torn, so that the existing cold saw circular saw blade is generally free of the silencing line. The saw blade of the existing cold saw circular saw blade has large vibration noise during cutting work, so that the cutting section looks smooth and actually is wavy, the workpiece needs secondary processing when being used for other purposes, the smoothness of the section is caused by irregular friction during left-right oscillation of the saw blade bit, and the saw blade is easy to overheat and blunt.
Disclosure of Invention
The invention aims to provide the efficient cold saw circular saw blade which is simple in structure, smooth in cutting section and long in service life.
In order to realize above-mentioned purpose, this circular saw blade 8 does not have inflation groove and is equipped with tool bit 5 and amortization line 4 in the 8 outside sides of circular saw blade, is equipped with mounting hole 7 and centre bore 6 in 8 piece center sides of circular saw, and amortization line 4 is that 8 two-sided run-through of circular saw blade, radial centripetal rectangular structure have many to distribute on circular saw blade 8 in circumference, the radial range that amortization line 4 set up outside the 2/3 of 8 radiuses of circular saw blade, inwards be greater than the circumference scope 3 between 10mm apart from the tooth bottom 9, the circumference scope that every amortization line set up, in 8 two radial centripetal ray contained angles B1 of circular saw blade be within 10 fan-shaped and the amortization line region 2 of circumference scope 3 coincidence formation. Through the arrangement, the invention adopts the position of the silencing line to properly obstruct the vibration of the cold saw circular saw blade, can realize the good flatness of the section of the cut workpiece, the lines of each cut are clear and visible, and the invention also mutually proves that the cutting of the cutter head is stable and has little vibration sound in the cutting process, and simultaneously eliminates the friction between the side surface of the cutter head and the cutting gap, so that the power loss of the saw is reduced, the heating of the workpiece and the saw blade is less, and the saw blade can keep the requirement of the best cutting performance for a long time.
Drawings
The invention will now be further described with reference to the accompanying drawings.
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1. the included angle B of the centripetal ray is 2, the noise reduction line area is 3, the circumferential range is 4, the noise reduction line area is 5, the cutter head is 6, the center hole is 7, the mounting hole is 8, the circular saw blade is 9 and the tooth bottom is formed.
Detailed Description
As shown in figure 1, the circular saw blade 8 of the invention is assembled, the center hole 6 is used for centering, the mounting hole 7 is used for preventing slipping during the operation, the cutting rigidity of the saw blade is not influenced and the vibration transmission path is damaged and the vibration of the tooth end of the saw blade is eliminated under the condition that the influence of the expansion groove is removed through the silencing line at the position of the circular saw blade 8 during the cutting operation. Through the arrangement, when the saw blade cutting machine is used for cutting, the saw blade rotates smoothly, friction noise is avoided, the abrasion of the saw blade is reduced, and the flat section of a workpiece has clear lines. All changes and modifications that come within the spirit of the invention are desired to be protected.
Claims (3)
1. The utility model provides a high-efficient cold saw blade which characterized in that: the circular saw blade is provided with the tool bit and the silencing line on the outer side of the circular saw blade without the expansion groove, and the central side of the circular saw blade is provided with the mounting hole and the central hole.
2. A high efficiency cold saw circular saw blade as claimed in claim 1, wherein: the amortization line is that the circular saw blade is two-sided to run through, radial entad rectangular structure, has many to distribute on the circular saw blade in circumference.
3. A high efficiency cold saw circular saw blade as claimed in claim 1, wherein: the radial range that the amortization line set up outside 2/3 of circular saw blade radius, inwards be apart from the circumference scope between the tooth bottom and be greater than 10mm, the circumference scope that every amortization line set up, in the amortization line region that two radial centripetal ray contained angles B of circular saw blade are 10 fan-shaped and circumference scope coincidence formation.
