Abstract
The utility model discloses a wire guiding wheel for a multi-wire sawing machine. A wire guiding groove is a V-shaped groove of which the angle ranges from 100 degrees to 120 degrees. The utility model has the benefits that the 60-degree angle of the V-shaped groove of an original wire guiding wheel is changed into an angle of 100-120 degrees, the groove depth is changed from the original 5mm to 2.5mm, and the groove width is changed from the original 3mm to 5mm, so that the swing amplitude of a lead wire in the wire guiding groove is increased, and the contact area between the lead wire and the wire guiding wheel is also enlarged. Therefore, low probabilities of wire clamping and breakage are achieved, and the eccentric wear probability is remarkably lowered. The service life of the lead wire is prolonged and the cost is saved.
Description
Technical field
The utility model relates to a kind of guide roller, and especially a kind of multi-line cutting machine guide roller is applicable to the semi-conductor silicon chip processing technique field.
Background technology
Silicon chip is the main production material in semiconductor and photovoltaic field.The silicon chip multi-line cutting machine is present more advanced in the world silicon chip process equipment, and its principle is that the steel wire through a high-speed motion drives and attached to the cutting blade material on the steel wire silicon rod rubbed, thereby reaches cutting effect.In whole process, steel wire on the main line roller, form a bracing cable net, and workpiece to be processed is realized the feeding of workpiece through the decline of workbench through the guiding of tens guide rollers.Guide roller commonly used at present is that angle is 60 degree " V " shape grooves, groove depth 5mm, groove width 3mm.Because angle is little, wire casing is dark, thereby has ensured the lead precision; But also so easily cause dark mill; Because " V " type bottom land end causes thin and narrow and small wearing clearance vertically downward, this gap two walls are as easy as rolling off a log to cause clamp to the steel wire that slight swing and high-speed cruising are arranged, and causes the steel wire rupture pull force to exceed standard or clamp; Cause broken string, damage workpiece to be processed.
The utility model content
It is big that the utility model technical problem to be solved provides a kind of " V " shape angle of the v-groove, and bottom land is mild, is not easy to cause the multi-line cutting machine guide roller of clamp or broken string.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of multi-line cutting machine guide roller, its metallic channel are " V " shape grooves, and the angle of said " V " shape groove is 100 °～120 °.
Preferably, the angle of said " V " shape groove is 110 °.
The degree of depth of said " V " shape groove is 2.5mm, and width is 5mm.
Adopt the beneficial effect that technique scheme produced to be: the described multi-line cutting machine guide roller of the utility model changes 100 °～120 ° through the angle with former guide roller " V " shape groove into by 60 °; Change groove depth into 2.5mm by original 5mm; Groove width changes 5mm into by original 3mm, and the amplitude of fluctuation when lead moves in metallic channel like this strengthens, and lead and guide roller contact area also strengthen thereupon; Thereby be difficult for causing the phenomenon of clamp, broken string, cause the probability of eccentric wear also to reduce significantly.Prolong the service life of lead, practiced thrift cost.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the front view of the utility model guide roller;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Can know that like Fig. 1-embodiment shown in Figure 2 the described multi-line cutting machine guide roller of the utility model, its metallic channel are " V " shape grooves, the angle A of " V " shape groove is 110 °; The degree of depth of " V " shape groove is 2.5mm, and width is 5mm.
Guide roller before so improving, the angle of metallic channel increases, and bottom land tends towards stability slightly, and lead wear point area more in the past increases, and wearing depth reduces, and wearing clearance increases, and is difficult for causing clamp or broken string, in the service life of extension lead, reduces production costs.
Claims (3)
1. multi-line cutting machine guide roller, its metallic channel is " V " shape groove, it is characterized in that, the angle of said " V " shape groove is 100 °～120 °.
2. a kind of multi-line cutting machine guide roller according to claim 1 is characterized in that, the angle of said " V " shape groove is 110 °.
3. a kind of multi-line cutting machine guide roller according to claim 1 and 2 is characterized in that, the degree of depth of said " V " shape groove is 2.5mm, and width is 5mm.
