Accompanying drawing and drawing are described as follows:

Fig. 1 is total figure of the present utility model.

Fig. 2 is tubing rotation of the present utility model and clamping device figure.

Fig. 3 is cutting gun translating device figure of the present utility model.

Fig. 4 is the A-A view of Fig. 1.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Referring to Fig. 1, fuselage 6 comprises casing 45 and base 46, and plasma generator 4 places the base both sides.

Referring to Fig. 2, tubing rotation and clamping device 1 comprise stepper motor 7, synchronous toothed belt transmission 8, main shaft 9, swivel joint 10, carbon brush 11 and air clamper 13.Main shaft 9 is hollow, for the usefulness of putting into tubing 18 to be cut, in the hollow outside of main shaft bar axially extending bore 14 is arranged, there is bar radial direction through hole 15 to be communicated with outside the through hole 14 with the annular groove 16 of swivel joint 10, compressed air is in import 17, annular groove 16, through hole 15 and 14 enter the cylinder (not shown on the figure) of main shaft two ends air clamper 13 respectively, by cylinder inner carrier and piston rod, to clamp tubing to be cut.During Pipe Cutting, the stepper motor rotation is rotated to drive main shaft, air clamper and tubing to be cut by the synchronous toothed belt transmission.The speed of rotary speed is adjusted as required automatically by electrical control gear.Carbon brush 11 is fixed on the support 12, slides on the copper sheathing 19 that rotates with main shaft 9, and carbon brush is as negative pole during Pipe Cutting.

Referring to Fig. 1, Fig. 3 and Fig. 4, the cutting gun device comprises plasma cutting gun 24, pikestaff 23, gun rack body 20, gun rack lid 21 and bolt 22.24 two tops that are loaded on tubing to be cut two ends respectively of cutting gun, the pikestaff 23 of cutting gun is fastening by screw and nut by gun rack body 20 and gun rack lid 21, tilt to cut out groove etc. as the needs cutting gun, can unclamp screw and nut pikestaff is turned to after the required angle tighten the screws nut again.The cutting gun device is fixed on the connecting rod 47 of cutting gun translating device slide mass 29 by bolt 22.

Referring to Fig. 1, Fig. 3 and Fig. 4, the cutting gun translating device comprises saddle 32, polished rod 25, screw mandrel 26, stepper motor 28, connecting rod 47 and slide mass 29, saddle 32 can be subdivided into support body 33, leads pawl 34 and lead pawl 35, lead pawl 35 stocks on polished rod 25 up and down, polished rod play the guiding role, and leads the screw and screw mandrel 26 interlock mutually of pawl 34.Before the Pipe Cutting, clamp screw mandrel 26 outer end square toes 27, can drive the saddle translation, with coarse adjustment saddle horizontal level with rotary screw rod.Dovetail groove 31 is arranged on the support body 33, slide mass 29 has dovetail groove 30, the connecting rod 47 of fixing the cutting gun device is connected on the slide mass 29, the stepper motor 28 that is fixed on the fixed mount 49 connects screw mandrel, screw mandrel and slide mass 29 interior fixedly connected screw (all not shown on screw mandrel and the screw figure) interlocks mutually have cover 48 outside the slide mass 29.Starting stepper motor rotates with drive lead screw, screw mandrel drives screw together with slide mass 29 and connecting rod 47, slide in dovetail groove 31 by dovetail 30, move horizontally so that drive the cutting gun that is fixed on the translating device 3 during Pipe Cutting, point-to-point speed is adjusted automatically by electrical control gear as required.

Referring to Fig. 1 and Fig. 4, middle plate at fuselage has the arc of screening curtain device 5 for 43 times, comprise and hide arc curtain 40, pull bar 38, connecting rod 37, piston rod 36 and cylinder 39, plate was 43 times during pull rod shaft 42 on the pull bar 38 was fixed in by support 41, pull bar 38 right-hand members link to each other with screening arc curtain, the pull bar left end links to each other with connecting rod 37, and connecting rod 37 left ends link to each other with piston rod 36, and plate was 43 times during cylinder 39 was fixed in.There is dust cover 44 tubing rotation and clamping device outside.When the piston rod 36 of cylinder 39 moves right to terminal (as shown in Figure 4), drive pull bars 38 counterclockwise around pull rod shaft 42 rotations by connecting rod 37, hide arc curtain 40 and reset thereby drive, the plasma arc when blocking Pipe Cutting.When stopping Pipe Cutting and loading and unloading tubing 18, the piston bar is moved to the left, and does the clockwise direction rotation by connecting rod to drive pull bar, and clockwise direction goes to unlimited thereby drive hides the arc curtain.

The Pipe Cutting operation is as follows: earlier with tubing charging apparatus 1 to be cut, and feed compressed air to clamp tubing, the horizontal displacement of coarse adjustment cutting gun starts stepper motor 7 and 28 simultaneously to tubing otch to be cut then, can cut out the intersection of required crossing tubing.But Pipe Cutting material one end or cut two ends simultaneously.

The contrast prior art, the utlity model has following advantage: kerf quality is good, the efficient height, cost is lower.
