The specific embodiment
In giving the processing of building block (blank) fluting, the shape of groove cross section can be rectangle, trapezoidal, triangle, but the trough line that this kind of mode of grooving outputed the cross section of groove is not straight line, but triangular tooth broken line can also be reprocessed into trapezoidal toothed broken line, straight line or other all geometry lines with hobboing cutter or broaching tool according to different demands.
Fig. 1 is the building block cross-sectional view that will process, and dash area is the processing capacity that will slot.Pressing existing equipment, is also needed cutting output, and processing capacity equals cutting output.
In Fig. 2, heavy line is illustrated in building block (blank) 2 two saw blades 1 that laterally relatively form an angle, and triangle ABC is processing capacity, and line segment AC, BC are cutting output, the width of saw kerf and saw into the degree of depth.In Fig. 2, can directly find out that the area sum of line segment AC, BC is much smaller than the area of triangle ABC.
Fig. 3 is the transversely arranged mode of widening groove of relative saw blade, the saw blade 1 that laterally relative tilt forms an angle between two, line segment AC, BC are cutting output, linear relative movement by saw blade 1 with building block (or blank) 2, realizes the ash mouthful required processing capacity of groove that completes building block with minimum cutting output.The quantity of saw blade, is to be decided by the angle between the groove width that will open and groove depth and two saw blades relatively.
Fig. 4 is the cross section bottom line shape (triangular tooth broken line) that saw blade cuts the groove of outputing, and in Fig. 5, bottom land is trapezoidal toothed broken line, and in Fig. 6, bottom land is straight line.
As shown in Figure 7, with the many groups of saw blades 1 that laterally relative tilt forms an angle between two, by the opposing parallel rectilinear motion of saw blade and building block (or blank) 2, and add building block in man-hour (or blank) the 2nd, from one end relative to saw blade 1, start to do opposing parallel rectilinear motion and cut, until building block (or blank) 2 departs from and just completes processing with all saw blades 1, realize the ash mouthful required processing capacity of groove that completes building block with minimum cutting output.
The angle of the angle of the saw blade of two horizontal relative tilts determines by groove depth, and the darker angle of groove is larger.The angle of the saw blade of two horizontal relative tilts is between 30 °～150 °, and the present embodiment be take 60 ° as example; By can be in a linear relative movement just can by the wide width that reaches required groove of fluting, by a plurality of saw blades, be that one group of width along groove is arranged (transversely arranged), to organize saw blade more simultaneously and arrange along its length (being longitudinal arrangement), the wider horizontal every group of saw blade arranged of groove is more.At width one regularly, the angle of the darker saw blade of groove is larger, and every group of saw blade quantity of arranging is just fewer, and the group number of longitudinal arrangement is just more.Along saw blade, longitudinally see, the orthographic projection of all saw blades (in the width and the degree of depth of groove), saw blade crossing X-type cross between two before and after forming, and the bottom of X-type cross line joins between two continuously, phase contact is the crown of sawtooth, and two saw blades that only have corresponding pre-slotting both sides are to determine its angle of inclination by the cross-sectional edge geometry of pre-slotting (as trapezoidal, rectangle etc.).The higher upper and lower opening of height of X-type cross line is larger, and fractional energy savings is just higher.Adding building block in man-hour (blank) is from one end relative with saw blade, to start to do opposing parallel rectilinear motion to cut, until depart to building block and all saw blades, just completes processing.
In Fig. 7, the represented saw blade of the line of same type is same group of saw blade, is transversely arranged saw blade, and 1. total Four types is labeled as respectively, 2., 3., 4.; The represented saw blade of dissimilar broken line is saw blade on the same group not, is the saw blade of longitudinal arrangement.The saw blade of same group can not intersect, and before and after the saw blade of longitudinal arrangement, can change arbitrarily, as long as saw blade not on the same group all forms the intersection of X, just can realize fluting processing.
Laterally the saw blade of relative tilt, can be saw blade, as shown in Figure 8 and Figure 9; Also can be monolateral trapezoidal straight blade 102, as shown in Figure 10, Figure 11; Described monolateral trapezoidal straight blade 102 refers to that rear tooth increases successively than nipper, and till being increased to the degree of depth of required saw kerf, the amount of increasing of per tooth is to be determined by the speed of the mechanical strength of building block and building block and saw blade relative motion.
While adopting saw blade, be erected on knife rest 4, saw blade 101 must have two athleticisms to realize fluting processing, the one, the rotation of saw blade 101, the 2nd, the linear relative movement of building block 2 and saw blade 101.The compound of two motions just can complete processing, and this mode productivity ratio is high, and the precision of equipment is low, and the High Rotation Speed cutting of saw blade can produce dust, by setting up dust exhaust apparatus 3, solves this problem, and in realization processing, fractional energy savings is more than 70%.
While adopting monolateral trapezoidal straight blade 102, be erected on knife rest 4, by building block 2 and the linear relative movement of monolateral trapezoidal straight blade 102, completed machining, in process, can not produced dust.
