The edge cutting circular saw web structure is simple in structure, a gap is reserved between cutting edges so that sweeps can not enter the gap between the circular saw webs in the cutting process, smooth cutting of the cutting machine is ensured, and therefore waste of resources is reduced, working hours are shortened, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of cutting machine sword and cuts circular saw blade, specifically a kind of sword of cutter with double saw bits structure that cuts circular saw blade.
Background technology
At present, existing cutter with double saw bits is cut by force workpiece, and can not eliminate the gap in the middle of two saw blades, in the process that causes cutting, has scrap to enter the gap between two saw blades, inside and outside may making, saw blade friction increase is overheated causes the saw blade deformed damaged, and can not cut for a long time.In the cutting machine course of work, guarantee gap by shimming between inside and outside saw blade, but along with the vibration of saw blade, the time lengthening of cutting, two saw blades easily friction are collided, and cause the consequences such as broken teeth.
The utility model content
The sword that the purpose of this utility model the is to provide a kind of cutter with double saw bits structure that cuts circular saw blade, this transmission mechanism has convenience simple in structure, is convenient to install, and installation accuracy is high strengthens the advantage such as cutting service life.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of sword of cutter with double saw bits structure that cuts circular saw blade, it comprises fuselage, described fuselage one side is provided with two and is parallel to each other and concentric saw blade a and saw blade b, the axis of described saw blade a and saw blade b is provided with connecting hole a and the connecting hole b that is connected to turning cylinder, described saw blade a is arranged on the saw blade b outside, the saw blade a outside is provided with the saw blade nut, and the cutting edge of saw blade b comprises smear metal cutter head A and smear metal cutter head B.
Between described saw blade a and saw blade b saw blade, gap is 0.02-0.08mm, described smear metal cutter head A left and right inclination alpha is 45 °, the side rake angle r of smear metal cutter head A is 10 °, and smear metal cutter head A mono-side has boss, and described cutter tip B left and right angle of inclination beta is 45 °.
The length of described boss is 0.1-0.5mm, and the length of boss is greater than gap between saw blade a and saw blade b saw blade, and smear metal cutter head A is contrary with inclination angle, smear metal cutter head B left and right opening direction, and smear metal cutter head A and smear metal cutter head B alternative arrangement.
Operation principle: saw blade a does and moves clockwise, saw blade b does counterclockwise motion, and workpiece is carried out to sword and cut, and saw blade a plays preliminary cutting and to workpiece fixing effect in addition, the cutting edge that saw blade b is provided with two kinds of different structures plays the further smear metal effect of workpiece, between described saw blade a and saw blade b saw blade, gap is 0.02-0.08mm, smear metal cutter head A left and right inclination alpha is 45 °, the side rake angle r of smear metal cutter head A is 10 °, and smear metal cutter head A mono-side has boss, described cutter tip B left and right angle of inclination beta is 45 °, the length of described boss is 0.1-0.5mm, the length of boss is greater than gap between saw blade a and saw blade b saw blade, two kinds of saw blades adopt different structural designs, in order to eliminate the gap between two saw blades in two saw blade cutting process, reduced the frictional force between saw blade, increased smear metal intensity, the heat of having avoided the High Rotation Speed between saw blade to produce deforms saw blade, extended the physical life of saw blade, the saw blade of two move toward one another is in high speed rotating simultaneously, the saw blade of move toward one another can be offset a part of reaction force, can reduce the jitter of cutting machine, improve the precision of cutting.
In sum, the utility model characteristics are as follows: to work piece cut, by strong shear, be that sword is cut; The boss be provided with due to described smear metal cutter head A mono-side, thereby eliminate the gap between two saw blades in two saw blade cutting process, reduced the frictional force between saw blade, solved in the past in working angles because frictional force increases, the saw blade heating causes the fast problem of the saw blade cutting edge rate of wear; Gap during cutting between two saw blades is difficult for entering scrap, has strengthened saw blade lifetime and effective cutting stroke.

The specific embodiment
With reference to accompanying drawing, a kind of sword of cutter with double saw bits structure that cuts circular saw blade, it comprises fuselage, described fuselage one side is provided with two and is parallel to each other and concentric saw blade a and saw blade b, the axis of described saw blade a and saw blade b is provided with the installing hole that is connected to turning cylinder, described saw blade a is arranged on the saw blade b outside, and the saw blade a outside is provided with the saw blade nut, thereby saw blade a and saw blade b are axially rotated on identical horizontal line.
The cutting edge of described saw blade b comprises smear metal cutter head A and smear metal cutter head B, and smear metal cutter head A is contrary with inclination angle, smear metal cutter head B left and right opening direction, thereby strengthens the cutting power of saw blade.
Between the saw blade of described saw blade a and saw blade b, gap is 0.02-0.08mm, described smear metal cutter head A left and right inclination alpha is 45 °, side rake angle r is 10 °, and smear metal cutter head A mono-side is provided with the boss that a length is 0.1-0.5mm, described cutter tip B left and right angle of inclination beta is 45 °, smear metal cutter head A and smear metal cutter head B alternative arrangement.
