The above is structure and the configuration explanation thereof of each main member of the embodiment of the present invention.Make flowing mode and effect makes the following instructions as for of the present invention.
As Fig. 2, Fig. 4, Fig. 5, Fig. 7, Fig. 8, Figure 15 A, when the present invention carries out horizontal sawing operation, control this first, two band moving cells 40, 50 starts, make this first, two bucks 31, 32 and respectively driving wheel 62 and auxiliary wheel 63 provided thereon be positioned on same level, make the band saw 68 that is set around between this driving wheel 62 and auxiliary wheel 63 horizontal, now, control again this first, two band moving cells 40, 50 starts, make this first, two bucks 31, 32 respectively at this first, two saw carriages 21, 22 displacements that synchronously produce vertical direction in the equivalent mode, use and treat sawing thing 80 and carry out horizontal sawing operation.
In this being treated to sawing thing 80 carries out the process of horizontal sawing operation, once this band saw 68 is treated the contact area excessive (as shown in 15A figure) of sawing thing 80 with this, and the load that causes horizontal sawing is when excessive, visual demand is controlled this first band moving cell 40 or the second band moving cell 50 starts, as Fig. 7, Fig. 8 arranges in pairs or groups shown in Figure 13, lifting and controlling the second band moving cell 50 is example, make this second buck 32 and the second shifting seat 61 provided thereon, auxiliary wheel 66, and the second driven pulley 67 displacements vertically upward such as grade, or displacement vertically downward, it is example that Figure 15 B figure lifts displacement vertically upward, now, 62 of this auxiliary wheel 66 and this driving wheels be not on same level, the band saw 68 that makes to be set around between this driving wheel 62 and auxiliary wheel 66 is skewed (being right low left high), accordingly, change the saw cutting angle of this band saw 68, treat the contact area of sawing thing 80 to reduce this band saw 68 with this, and the output of being saved power.
As Fig. 7, Fig. 8 arrange in pairs or groups as shown in Figure 15 C, show and control this second band moving cell 50 starts, make this second buck 32 and the second shifting seat 65 provided thereon, auxiliary wheel 66, and the displacement vertically downward such as the second driven pulley 67, allow this auxiliary wheel 66 and this driving wheel 62 not on same level, the band saw 68 that makes to be set around between this driving wheel 62 and auxiliary wheel 66 is skewed (being right high left low), accordingly, the same saw cutting angle that changes this band saw 68, reduce this band saw 68 and treat the contact area of sawing thing 80 with this, and the output of being saved power.
It is worth mentioning that, be right low left high when skewed controlling this band saw 68, except controlling this second band moving cell 50 starts, make outside this second buck 32 and each assembly displacement vertically upward provided thereon, also can control this first band moving cell 40 starts, make this first buck 61 and each assembly displacement vertically downward provided thereon, same capable of regulating goes out this band saw 68, and to be right low left high skewed.In like manner, when this band saw 68 of control is the left low dip shape of right height, except controlling this second band moving cell 50 starts, make outside this second buck 32 and assembly displacement vertically downward provided thereon, also can control this first band moving cell 40 starts, make this first buck 31 and assembly displacement vertically upward provided thereon, same capable of regulating goes out this band saw 68 and is the left low dip shape of right height.
It should be noted that, as shown in Figure 12 to Figure 14, in the process of adjusting these band saw 68 saw cutting angles, due to this first buck 31 and assembly provided thereon with can produce one high and one low state in this second buck 32 and assembly provided thereon, and for fear of winding at this driving wheel 62, the first driven pulley 63, auxiliary wheel 66, and the band saw 68 of the second driven pulley 67 produces tired in the process of adjusting, the states such as fracture, therefore controlled band saw adjustment unit 70 starts that set up in this second shifting seat 65, to drive the horizontal displacement on this second shifting seat 65 of this auxiliary wheel 66, allow this band saw 68 be relaxed state in the process of adjusting saw cutting angle, generation with the states such as tired or fracture of avoiding band saw 68, and after this band saw 68 is adjusted saw cutting angle, make this band saw 68 be tensioning state, in order to the sawing operation, carry out smoothly.In Figure 14, the piston rod 712 of controlling this cylinder pressure 71 stretches out towards these the second buck 32 directions, and synchronously to drive this moving part 72, connecting rod 73 and auxiliary wheel 66 towards these the second buck 32 direction displacements, now, this band saw 68 is relaxed state.
Below through the specific embodiment and the embodiment the present invention is had been described in detail, but these not are construed as limiting the invention.Without departing from the principles of the present invention, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection scope of the present invention.
