Head 1 is also equipped with respectively the first adjustable block 6 of high and low position and the second block 7 near two positions up and down of movable block 8 one sides, in the time that the first nut 13 is encountered the first block 6 above being positioned at, show that saw blade 5 moves to highest position, the first nut 13 stops moving upward; In the time that the first nut 13 is encountered the second block 7 below being positioned at, show that saw blade 5 moves to its lowest position, the first nut 13 stops moving downward.
The first clamping device assembly 2 be installed in frame 9 and be positioned at saw blade 5 under, the first clamping device assembly 2 clamp steel pipe 11 and be positioned at saw blade 5 under, saw blade 5 pipe cuttings 11 can not produce additional stress, cutting more easily easily.
The first clamping device assembly 2 has a structure and identical the second clamping device 20 of the first clamping device assembly 2 along the direction of feed of steel pipe 11, and the second clamping device 20 also can clamp steel pipe 11.
The second clamping device 20 is enclosed within on the second ball-screw 22 by the second nut 21, one end of the second ball-screw 22 is arranged on the first clamping device assembly 2 by bearing, the other end is connected to by shaft coupling on the output shaft of the 3rd reducing motor 24, the 3rd reducing motor 24 is arranged in frame 9 by base 23, therefore, the rotation of the 3rd reducing motor 24 output shafts can drive the second clamping device 21 and the second clamping device 20 to move.
On the second clamping device 20, slide rule 25 is installed, corresponding quiet chi 26 is installed in frame 9, and in the time that the second clamping device 20 moves, slide rule 25 does relative motion with respect to quiet chi 26, can measure the displacement of the second clamping device 20.
As shown in Figure 3, the second clamping device 20 is identical with the structure of the first clamping device assembly 2, and the first clamping device assembly 2 comprises the 4th reducing motor 27, hold-down support 28, the 3rd ball-screw 29, slide 30, the 3rd nut 31; Hold-down support 28 is fixed in frame 9, one side of hold-down support 28 is provided with the 4th reducing motor 27, the output shaft of the 4th reducing motor 27 connects the 3rd ball-screw 29 by shaft coupling, the other end of the 3rd ball-screw 29 is arranged in frame 9 by bearing, and the middle part cover of the 3rd ball-screw 29 has the 3rd nut 31, the three nuts 31 to be connected on slide 30, therefore, hold-down support 28 maintains static, and in the time that the output shaft of the 4th reducing motor 27 rotates, drives slide 30 to move; When slide 30 is near hold-down support 28, and steel pipe 11 is clamped; When slide 30 is away from hold-down support 28, and steel pipe 11 is unclamped.
The second reducing motor 4 adopts servomotor, therefore its rotary speed is adjustable, and the movement velocity of the first nut 13 is also that the feed speed of saw blade 5 is adjustable, when saw blade 5 down moves to while also not touching steel pipe 11 at highest point, owing to being idle stroke, can allow saw blade 5 down move fast; In the time that saw blade 5 touches steel pipe 11 at once, for reducing to impact, the feed speed of controlling saw blade 5 should be less; After cutting is stable, in order to improve cutting efficiency, should again improve the feed speed of saw blade 5; Cut complete after, saw blade 5 need to be got back to peak position, is also at this moment idle stroke, also can adopt fast and move upward.
In the utility model, on the first block 6, primary importance sensor 16 is installed, the second block 7 is provided with the 4th position sensor 19, and the adjustable second place sensor 17 of high and low position, the 3rd position sensor 18 are also installed successively on head 1 between the first block 6 and the second block 7, the direction of feed of saw blade 5 and speed, can in program, set, the adjustable position sensor in several positions also can be installed on head 1, primary importance sensor 16, second place sensor 17, the 3rd position sensor 18, the 4th position sensor 19, the first block 6, primary importance sensor 16 and the 4th position sensor 19 are installed respectively on the second block 7, between the first block 6 and the second block 7, second place sensor 17 is installed, the 3rd position sensor 18, in the time that head 1 moves up to the first block 6, primary importance sensor 16 detects that saw blade 5 has moved to peak, the second reducing motor 4 stops the rotation, saw blade 5 stops moving upward, in the time that head 1 has just started to move downward, owing to being idle stroke, can allow saw blade 5 down move fast, in the time moving to second place sensor 17 place, second place sensor 17 detects to be that saw blade 5 touches steel pipe 11 at once, and the feed speed of controlling saw blade 5 should be less, saw blade 5 continues to move downward, and in the time moving to the 3rd position sensor 18, shows that cutting enters the stabilization sub stage, in order to improve cutting efficiency, improves the feed speed of saw blade 5 again, saw blade 5 continues cutting downwards, detects that to be that steel pipe 11 cuts complete until move to the second block 7, the four position sensors 19, and the second reducing motor 4 fast rotational allow saw blade 5 return fast until the first block 6 places.
The high and low position of the first block 6, the second block 7 and second place sensor 17, the 3rd position sensor 18 is adjustable, and in the time that the diameter of steel pipe 11 is different, the position of adjusting four position sensors can adapt to the cutting of the steel pipe 11 of different-diameter.
In the time that steel pipe need to cut, its workflow is as follows:
(1) feed mechanism is sent steel pipe 11 come to, and the first clamping device assembly 2 clamps steel pipe 11;
(2) first motors 3 drive saw blade 5 to rotate;
(3) second reducing motor 4 fast rotational drive the top of saw blade 5 rapid movements to steel pipe 11;

(5), after cutting is stablized, the second reducing motor 4 rotary speeies raisings improve the feed speed of saw blade 5 again, to improve cutting speed and efficiency;
(6) in the time that movable block 8 is encountered the second block 7, show that steel pipe cutting is complete, the second reducing motor 4 saw blade 5 feed-disablings that stop the rotation, and oppositely shorten and move upward fast, in the time that movable block 8 is encountered the first block 6, show that saw blade 5 moves to highest position, the second reducing motor 4 stops reverse rotation;
(7) the above-mentioned cutting that completes 11 1 sections of steel pipes, feed mechanism is sent steel pipe 11 to again, repeats the step of (1)-(6), until final stage;
(8) after the steel pipe 11 that final stage need to cut is sent to by feed mechanism, the 3rd reducing motor 24 rotates, drive the second clamping device 20 to move to the side near the first clamping device assembly 2, slide rule 25 records on the second clamping device 20 move to leftmost position;
(9) second clamping devices 20 clamp steel pipe 11, the first clamping device assembly 2 unclamps steel pipe 11, the 3rd reducing motor 24 counter-rotates, drive the second clamping device 20, steel pipe 11 away from the first clamping device assembly 2, slide rule 25 on the 3rd reducing motor 24 moves on quiet chi 26, in the time that slide rule 25 measures mobile distance and reaches requirement, the 3rd reducing motor 24 stops the rotation, and the second clamping device 20 stops mobile;
(10) first clamping device assemblies 2 clamp steel pipe 11, repeat the action of (2)-(6), complete the cutting of final stage.
Automation when the utility model automatic cutter for steel pipes saw blade clamping and mobile device can be realized the cutting of steel tube cutting machine saw blade, and make the impact of saw blade less.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
