Description
Technical field
The invention belongs to electric tool aid field, and in particular to a kind of cutting machine special-purpose metal section.
Background technology
Cutting sheet is under the jurisdiction of emery wheel, made of abrasive material and bonding agent resin etc. be used for common iron, stainless steel metal and
The thin slice of non-metallic material.
Current metal tube cutting sheet is divided into two species, first, emery disc form cutting sheet, it is characterised in that the cutting
Piece material is emery wheel, drives emery disc form cutting sheet to tell rotation and the direct severe friction of cut pipe fitting, metal by clicking on
With emery disc form cutting sheet in friction, largely wearing all occurs pipe fitting in two kinds of contact surface, and metal tube is cut so as to realize to break
Tube wall, its friction cuttings principle is that grains of sand hardness in emery disc form cutting sheet is more than and is cut metal, but is glued between the grains of sand
It is low to connect precision, such product shortcoming is that the high wear rate of cutting sheet, and the cutting sheet replacement cycle is short, and construction cost is high, such as
Fruit is more low for higher metal tube its cutting efficiency of hardness.Its material of another cutting sheet is metal, is cut
Zigzag is presented in the edge of pitch cutting, drives zigzag cutting sheet to rotate with cut pipe fitting firmly to cut at a high speed by motor
Cut, sawtooth Fast Wearing passivation in cutting process needs to polish to sawtooth one by one, keeps sharp, cutting sheet loss is rapid, saw
The process of tooth polishing is cumbersome, and the polishing of sawtooth also causes the reduction of cutting operation efficiency, meanwhile, such structure cutting sheet is cut
Section after cutting is uneven, and the fixation in cutting operation to cutting pipes is also highly difficult, easily occurs being cut pipe fitting bounce
Situation, the reduction for also resulting in cutting efficiency is damaged in cut edge by a small margin.
Meanwhile cutting in kind is carried out using cutting sheet, substantial amounts of noise can be produced, affects the physical and mental health of people.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide a kind of cutting machine special-purpose metal section.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of cutting machine special-purpose metal section, it is created
New point is：Including basal disc, the centre of the basal disc is provided with circular motor shaft fixing hole, is provided with the edge of the basal disc
It is the side seam that the center of circle is circularly set around motor shaft fixing hole, is additionally provided between the outer rim and motor shaft fixing hole of the basal disc
Several sound attenuation holes, the outer surface of the basal disc are installed with a wearing layer, and the thickness of the wearing layer is 1-2mm.
Further, the number of the sound attenuation hole is 4-6, and the structure of the sound attenuation hole is hornet's nest shape, the noise elimination
Several small noise elimination endoporus are provided with hole, sound-absorbing material is placed with the noise elimination endoporus.
Further, the radical of the side seam is 20-24 roots, and the width of the side seam is 1-2mm, the length of the side seam
For 1-1.5cm.
Beneficial effects of the present invention are as follows：
（1）The present invention by adding sound attenuation hole, effectively reduce cutting sheet work caused by noise, further protect work
Make the physical and mental health of personnel.
（2）The friction part of the cutting sheet of the present invention is the edge of whole cutting sheet, and integrated exposure area is big, unit area
On temperature it is low, the position of friction is just participated in cutting sheet rotary course will leave friction and be cut position to be in air and carry out
Appropriate cooling, the temperature at cutting sheet edge is well below the temperature of the cutting part of cut metal tube, its hardness on the whole
It is unaffected, while under the side seam structure that sets of disk border hangs the part of the cut metal tube of softening, so as to realize
The cutting operation crucial to cutting.
（3）The present invention is installed with wearing layer by the outer surface in basal disc, can effectively increase the service life.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
As shown in figure 1, a kind of cutting machine special-purpose metal section, including basal disc 1, the centre of the basal disc 1 are provided with circle
Motor shaft fixing hole 3, it is side seam 2 that the center of circle is circularly set to be provided with the edge of the basal disc 1 around motor shaft fixing hole 3,
Several sound attenuation holes 4 are additionally provided between the outer rim and motor shaft fixing hole 3 of the basal disc 1, the outer surface of the basal disc 1 is fixed
One wearing layer 11 is installed, the thickness of the wearing layer 11 is 1-2mm.The present invention in the outer surface of basal disc 1 by being fixedly mounted
There is wearing layer 11, can effectively increase the service life.
The number of the sound attenuation hole 4 is 4-6, and the structure of the sound attenuation hole 4 is hornet's nest shape, is set in the sound attenuation hole 4
Several small noise elimination endoporus are equipped with, sound-absorbing material is placed with the noise elimination endoporus 4.The present invention has by adding sound attenuation hole 4
Effect reduce cutting sheet work caused by noise, further protect the physical and mental health of staff.
The radical of the side seam 2 is 20-24 roots, and the width of the side seam 2 is 1-2mm, and the length of the side seam 2 is 1-
1.5cm。
The friction part of the cutting sheet of the present invention is the edge of whole cutting sheet, and integrated exposure area is big, in unit area
Temperature it is low, the position of friction is just participated in cutting sheet rotary course will leave friction and be cut position to be in air and fitted
Work as cooling, the temperature at cutting sheet edge is well below the temperature of the cutting part of cut metal tube on the whole, and its hardness is not
It is impacted, while under the side seam structure that sets of disk border hangs the part of the cut metal tube of softening, so as to realize pair
Cut crucial cutting operation.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as
The technical scheme that can be realized on the basis of above-described embodiment without creative work, it is regarded as falling into patent of the present invention
Rights protection scope in.
