Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model discloses a saw blade cutting machine for metal pipe processing, comprising a base 1 and a turning table 2 rotatably connected to the base 1, round shafts are fixed on both sides of the turning table 2, a connecting sleeve is fixed on the base 1, the round shaft is movably connected to the inner wall of the connecting sleeve, and the turning table 2 rotates with the round shaft as the axis, and also includes:

[0026] The sawing mechanism 3 includes a motor 31 fixed in the base 1. The motor 31 is powered by an external power supply. A saw blade body 32 for sawing the metal pipe is fixed at the output end of the motor 31. A turning mechanism 5 is arranged at the rear side of the turning table 2. The turning mechanism 5 is used to drive the turning table 2 to rotate. A length limiting strip 6 for limiting the position of the metal pipe is arranged on the turning table 2. The length limiting strip 6 is fixed to the turning table 2 by bolts. A plurality of threaded holes are provided on the turning table 2. The length limiting strip 6 is fixed to the threaded holes at different positions. The length of the metal pipe at the cutting position changes accordingly.

[0027] The clamping assembly 4 includes a front clamping rod 41 and a rear clamping rod 42 which are slidably connected to the flip table 2. The front clamping rod 41 and the rear clamping rod 42 are used to clamp and position the metal rod. A connecting block 43 is fixed on the front clamping rod 41. A screw 47 is rotatably connected in the connecting block 43. A bearing is embedded in the connecting block 43. The screw 47 is rotatably connected to the connecting block 43 through the bearing. The screw 47 can only rotate in the connecting block 43 through the bearing to prevent the screw 47 from moving forward and backward during rotation. An internal thread block 44 is threadedly connected to a screw rod 47, and a hand wheel 45 is fixed to the end of the screw rod 47. The hand wheel 45 is used to conveniently rotate the screw rod 47, thereby facilitating the clamping and positioning of the metal tube. The metal tube is placed between the front clamp rod 41 and the rear clamp rod 42, and the screw 47 is rotated so that the front clamp rod 41 and the rear clamp rod 42 clamp the metal tube. The front clamp rod 41 is then pushed to move the metal tube to the position of the saw blade body 32. The motor 31 drives the saw blade body 32 to rotate at a high speed, and the saw blade body 32 performs sawing processing on the metal tube.

[0028] Specifically, the turning mechanism 5 includes a hydraulic cylinder 51 rotatably connected to the base 1 , a rotating shaft 52 is fixed at the notch on the rear side of the turning platform 2 , and a telescopic end of the hydraulic cylinder 51 is movably sleeved on the surface of the rotating shaft 52 .

[0029] In this implementation plan, please refer to Figure 5 The end of the piston rod of the hydraulic cylinder 51 is movably sleeved on the rotating shaft 52, and the bottom of the hydraulic cylinder 51 is rotatably connected to the base 1 through a connecting seat. When the piston rod of the hydraulic cylinder 51 is extended, the turning table 2 can be driven to turn upward through the rotating shaft 52. When the piston rod of the hydraulic cylinder 51 is shortened, the turning table 2 can be driven to turn downward and fit onto the base 1.

[0030] Specifically, the turning angle of the turning table 2 ranges from zero to eight degrees.

[0031] In this implementation plan, please refer to Figure 5 , to prevent the turning table 2 from turning over too much, causing the metal pipe to be unable to contact the saw blade body 32.

[0032] Specifically, guide blocks 46 that slide forward and backward along the inner wall of the guide groove on the turning table 2 are fixed to the bottom of the front clamping rod 41 and the rear clamping rod 42 , and the guide blocks 46 are used to guide the movement of the front clamping rod 41 and the rear clamping rod 42 .

[0033] In this implementation plan, please refer to Figure 3 and Figure 4 When the front clamping rod 41 and the rear clamping rod 42 move, the guide block 46 is driven to move along the inner wall of the guide groove. The guide block 46 guides the movement of the front clamping rod 41 and the rear clamping rod 42, so that the movement of the front clamping rod 41 and the rear clamping rod 42 is more stable and smooth.

[0034] Specifically, the guide block 46 is in an isosceles trapezoidal shape, and is used to improve the guiding capability of the front clamping rod 41 and the rear clamping rod 42 .

[0035] In this implementation plan, please refer to Figure 3 and Figure 4 The contact area with the guide groove is increased by the isosceles-reminding guide block 46, thereby improving the guiding ability of the front clamping rod 41, the rear clamping rod 42 and the metal pipe during movement, thereby improving the accuracy of metal pipe sawing.

[0036] Specifically, the opposite surfaces of the front clamping rod 41 and the rear clamping rod 42 are both provided with V-shaped notches for clamping and fixing the circular tubular metal pipe.

[0037] In this implementation plan, please refer to Figure 2 The V-shaped notch is suitable for clamping and fixing the round tubular metal tube, and the planes at the opposite surfaces of the front clamping rod 41 and the rear clamping rod 42 are suitable for clamping and fixing the square metal tube, thereby improving the adaptability to the metal tube.

[0038] Specifically, a protective cover is fixed to the side of the motor 31 , and the protective cover is used to protect the saw blade body 32 .

[0039] In this implementation plan, please refer to Figure 5 The protective cover is placed over the high-speed rotating saw blade body 32 to prevent foreign objects from contacting the saw blade body 32 , thereby protecting the saw blade body 32 .

[0040] The working principle and use process of the utility model are as follows: a metal pipe is placed between the front clamping rod 41 and the rear clamping rod 42, and the hand wheel 45 is held to rotate the screw rod 47, so that the screw rod 47 rotates through the internal thread block 44 to drive the rear clamping rod 42 to move forward, so that the front clamping rod 41 and the rear clamping rod 42 clamp the metal pipe, and then the front clamping rod 41 is pushed to move the metal pipe to the position of the saw blade body 32, and the motor 31 drives the saw blade body 32 to rotate at a high speed, and the saw blade body 32 performs sawing processing on the metal pipe;

[0041] The front clamping rod 41 and the rear clamping rod 42 drive the guide block 46 to move along the inner wall of the guide groove on the top of the turning table 2 during the movement. The guide block 46 guides the movement of the front clamping rod 41 and the rear clamping rod 42, so that the movement of the front clamping rod 41, the rear clamping rod 42 and the metal pipe is more stable, thereby improving the sawing accuracy of the metal pipe;

[0042] A length limiting strip 6 is installed on the turning table 2. The position of the length limiting strip 6 is adjusted so that the length of the length limiting strip 6 from the saw blade body 32 corresponds to the required cutting length. Then, the end of the metal tube is pressed against the side of the length limiting strip 6 and the metal tube is moved to saw. After the sawing is completed, the length of the metal tube between the saw blade body 32 and the length limiting strip 6 is the required length of the metal tube.

[0043] After the hydraulic cylinder 51 is started, the piston rod extends and drives the turning table 2 to rotate through the rotating shaft 52, so that the turning table 2 is tilted. After the turning table 2 rotates, the height of the saw blade body 32 on the turning table 2 is reduced accordingly. After the reduction, the metal pipe can be prevented from being cut off as a whole, and a groove can be cut on the metal pipe. The angle of the turning table 2 is adjusted by the hydraulic cylinder 51 to change the height of the saw blade body 32 on the turning table 2, thereby cutting grooves of different depths to meet different usage requirements.
