[0026] In the embodiment, the bearing one 6 and the bearing two 9, in cooperation with the elastic deformation of the spring one 12, the rotation of the bearing seat 13 and the elastic deformation of the spring two 16 in the guiding mechanism two all absorb and buffer the shock energy generated in the sawing process of the band saw blade, avoid the direct rigid conduction of the shock to the whole saw bow, thereby reducing the shock of the saw bow, improving the effect and stability of the sawing process, prolonging the service life of the band saw blade, and changing the traditional rigid connection mode by the spring one 12 and the spring two 16. When the band saw blade generates shock, the spring one 12 and the spring two 16 can be elastically deformed to absorb and buffer the impact load, overcoming the problem that the full rigid contact in the prior art cannot eliminate the impact load.

[0027] As shown in Figure 2 and Figure 3 A clamping mechanism is arranged between the guiding seat 3 and the lower side of the fixed plate 1, and the clamping mechanism includes an oil channel 18, the oil channel 18 is arranged vertically on the inner side of the middle of the guiding seat 3, a hexagonal plug 19 is threadedly connected to the top end of the oil channel 18, a compression piston 20 is movably arranged at the bottom end of the guiding seat 3 and close to the inner side of the side of the fixed plate 1, an oil seal 21 is arranged between the compression piston 20 and the oil channel 18, and a plurality of tungsten clamping pieces 22 are arranged side by side on the same side of the fixed plate 1 and the compression piston 20.

[0028] In this embodiment, when the band saw blade is sawing, the pressure medium is injected into the oil way 18. Since the top end of the oil way 18 is sealed by the hexagonal plug 19, the pressure medium forms pressure in the oil way 18, pushes the compression piston 20 at the bottom end of the guide seat 3 and close to the inner side of the fixed plate 1 to move to the direction of the band saw blade. The oil seal 21 between the compression piston 20 and the oil way 18 prevents the leakage of the pressure medium, ensures the effective transmission of the pressure, and further makes the tungsten steel clamping pieces 22 arranged side by side with the fixed plate 1 and the compression piston 20 on the same side to clamp and fix the band saw blade, so that the band saw blade keeps stable during sawing and does not deviate, and the sawing precision is ensured.

[0029] As shown in Figure 1 The Y-shaped pipe joint 23 is arranged at the upper end of the left side of the guide seat 3. The cooling water outlet copper pipe one 24 and the cooling water outlet copper pipe two 25 are respectively communicated at the outlet end of the Y-shaped pipe joint 23. The other end of the cooling water outlet copper pipe one 24 is towards the upper end between the bracket 4 and the guide seat 3. The other end of the cooling water outlet copper pipe two 25 is towards the side of the guide seat 3 away from the bracket 4. The bottom ends of the cooling water outlet copper pipe one 24 and the cooling water outlet copper pipe two 25 are on the same horizontal line with the lower end surface of the bearing three 14. The cooling water outlet copper pipe one 24 and the cooling water outlet copper pipe two 25 are fixedly connected with the guide seat 3 through the plastic wire clamp 26.

[0030] In this embodiment, the cooling system composed of the Y-shaped pipe joint 23, the cooling water outlet copper pipe one 24 and the cooling water outlet copper pipe two 25 cools the band saw blade and related parts during sawing, reduces the heat generated by sawing friction, prevents the band saw blade and parts from being overheated to affect the performance and service life, and further ensures the effect and stability of sawing processing.

[0031] Working principle: when the band saw blade is sawing, inject pressure medium into the oil way 18, because the top of the oil way 18 is sealed by the hexagonal plug 19, the pressure medium forms pressure in the oil way 18, pushes the compression piston 20 at the bottom of the guide seat 3 and close to the inside of the fixed plate 1 to move to the direction of the band saw blade, the oil seal 21 between the compression piston 20 and the oil way 18 prevents the pressure medium from leaking, ensures the effective transmission of pressure, and then makes the tungsten steel clamping pieces 22 on the same side of the fixed plate 1 and the compression piston 20 to clamp and fix the band saw blade, ensures the band saw blade to keep stable during sawing and not to deviate, and ensures the sawing accuracy. When the band saw blade starts sawing and produces vibration, the guide mechanism one and the guide mechanism two work together to realize the damping effect, when the vibration is transmitted to the support 4, the bearing one 6 and the bearing two 9 can rotate to reduce the rotating friction, disperse and consume part of the vibration energy, at the same time, the spring one 12 outside the bolt one 11 will stretch and deform according to the vibration size, absorbs and buffers the vibration energy, when the vibration is transmitted to the guide seat 3, the bearing seat 13 can rotate around the rotating rod, the bearing three 14 reduces the rotating friction resistance, and the spring two 16 outside the left side of the bearing seat 13 is horizontally arranged, which will stretch and deform due to the displacement of the bearing seat 13, further absorbs and buffers the vibration energy, so as to effectively weaken the influence of the band saw blade vibration on the whole mechanism. During sawing, when the band saw blade generates heat due to friction, the cooling medium flows into the cooling copper pipe one 24 and the cooling copper pipe two 25 through the Y-shaped pipe joint 23, cools the band saw blade and related parts, reduces the heat generated by sawing friction, prevents the band saw blade and parts from affecting the performance and service life due to overheating, and ensures the effect and stability of sawing processing.
