Description

The tubing shear arrangement

Technical field

The utility model relates to a kind of pipe cutting machine, in particular on the tubing production line in accordance with regulations length cut off the device of tubing.

Background technology

Existing pipe cutting machine, welded tube shear arrangement particularly, the general metal cutting tools that adopts comes work to the mode that tubing cuts, during cutting, the mechanical shoulder cut-off knife tool of rotation is perpendicular to the tangential tubing of tubing axis at a high speed, can produce strong and harsh noise, and cutter is also fragile, is unsuitable for cutting heavy caliber pipe; The welded tube shear arrangement of existing employing gas cutting mode work is although there is baroque shortcoming in the noise that produces can reduce to cut the time.The disclosed a kind of similar structures of Chinese patent literature CN2080008 for example, in this structure, it is many around the parts that rotating mechanism adopts that tubing rotates to drive burning torch, and structure is complicated, and only be fit to the cutting of the tubing of inactive state, and can not online moving tubing be cut.

Summary of the invention

The purpose of this utility model is to provide a kind of can reduce cutting noise, simple and reasonable again, and can carry out the tubing shear arrangement of online cutting to tubing.

In order to achieve the above object, the utility model is by the following technical solutions: a kind of tubing shear arrangement, has the lengthwise movement frame, rack rail, clamp mechanism, rotating mechanism and burning torch, clamp mechanism is installed on the lengthwise movement frame, the lengthwise movement frame places on the rack rail movably, rotating mechanism comprises the wheel stand framework, guide wheel, turning circle, gear wheel, pinion and motor reduction gearbox, be contained in the motor reduction gearbox load pinion on the lengthwise movement frame, pinion and gear wheel engagement, gear wheel and turning circle are affixed or make one, on turning circle and the wheel stand framework and/or some guide wheels of arranging ringwise of installing on the lengthwise movement frame roll and cooperate.Some burning torch is installed on the turning circle.

After adopting said structure, owing to adopted the burning torch cutting, rather than the mechanical shoulder cut-off knife cutting, so can reduce cutting noise; Again owing to turning circle and gear wheel that some burning torches are housed in the rotating mechanism are affixed, so motor reduction gearbox just can drive gear wheel by pinion and turning circle rotates together, turning circle is because the guide wheel restriction that is subjected to arranging ringwise, can do to rotate reposefully around tubing, thereby make burning torch also around the tubing smooth rotation, tubing cuts off the most at last, the cutting accuracy height; The not only used parts of this structure are few, simple in structure, and can carry out online cutting to tubing, simultaneously, also are suitable for the online cutting of heavy caliber pipe.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

As Fig. 1,2, shown in 3, tubing shear arrangement of the present utility model, has lengthwise movement frame 3, rack rail 4, clamp mechanism 1, rotating mechanism 2 and burning torch 5, clamp mechanism 1 is installed on the lengthwise movement frame 3, lengthwise movement frame 3 places on the rack rail 4 movably, rotating mechanism 2 comprises wheel stand framework 2-1, guide wheel 2-2, turning circle 2-3, gear wheel 24, pinion 2-5 and motor reduction gearbox 2-6, be contained in the motor reduction gearbox 2-6 load pinion 2-5 on the lengthwise movement frame 3, pinion 2-5 and gear wheel 2-4 engagement, gear wheel 2-4 and turning circle 2-3 are affixed or make one, turning circle 2-3 go up with wheel stand framework 2-1 and/or lengthwise movement frame 3 on some guide wheel 2-2 that arrange ringwise of installing roll and cooperate.Some burning torch 5 is installed on the turning circle 2-3.

As shown in Figure 3, clamp mechanism 1 comprises clamping cylinder 1-1, clamp arm 1-2, clamp arm bearing 1-3 and clamp 1-4, clamping cylinder 1-1 and clamp arm bearing 1-3 are fixed on the lengthwise movement frame 3, the end of the hinged clamp arm 1-2 of clamping cylinder 1-1, clamp arm 1-2 middle part is hinged on the clamp arm bearing 1-3, but the clamp 1-4 of clamp arm 1-2 other end load clamping pipe periphery.

As shown in Figure 1, clamp mechanism 1 has two, lays respectively at the vertically moving on the frame 3 of turning circle 2-3 both sides.

As shown in Figure 1, 2, drive unit 3-1 is housed on the lengthwise movement frame 3, on the two ends output shaft 3-2 of drive unit 3-1 freewheel clutch pinion 3-3 is housed, the tooth bar 4-3 that installs on freewheel clutch pinion 3-3 and the rack rail 4 is meshed, lengthwise movement frame 3 next side are equipped with V-type slide guide wheel support 3-4 and V-type slide guide wheel 3-5, opposite side is equipped with horizontal sliding wheel support 3-6 and horizontal sliding wheel 3-7, and the shape of two rail bars of rack rail 4 then is respectively convex guide rail 4-1 that matches with V-type slide guide wheel 3-5 and the rectangular guideway 4-2 that matches with horizontal sliding wheel 3-7.

As shown in Figure 1, 2, burning torch 5 is contained in the front portion of cylinder 6, and cylinder 6 is contained on the upper slide rest 7, upper slide rest 7 and turning circle 2-3 load.Can regulate the distance between burning torch 5 and the tubing so easily, to improve the needs of cutting accuracy and the tubing that is suitable for different bores.

As shown in Figure 2, burning torch 5 is three plasma burning torches, and evenly distributes along turning circle 2-3.The quantity of burning torch 5 also can be 2～6.

When the utility model uses, as shown in Figure 1, 2, 3, after the tubing 8 of welding fabrication enters turning circle 2-3, by electric instruction, make clamp mechanism 1 action, its clamping cylinder 1-1 promotes clamp arm 1-2 action, makes clamp 1-4 be clamped in the periphery of tubing 8 tightly.Because clamp mechanism 1 is installed on the lengthwise movement frame 3, at this moment clamp mechanism 1 is with tubing 8 same moved further, also just drive whole lengthwise movement frame 3 along same moved further on the rack rail 4, guaranteed cutting accuracy, made it not to be subjected to tubing 8 and lengthwise movement frame 3 to move nonsynchronous the influence.At this moment, be in the freewheel clutch pinion 3-3 of drive unit 3-1 load on the lengthwise movement frame 3 and surmount state, on tooth bar 4-3, rotate passively, when clamp mechanism 1 clamping tubing 8 travels longitudinally, by electric instruction, turning circle 2-3 in the rotating mechanism 2 also rotates under the driving of motor reduction gearbox 2-6 and pinion 2-5, gear wheel 2-4, drives burning torch 5 and rotates; Meanwhile, burning torch 5 igniting are cut tubing 8, finish the flying shear operation.After flying shear is finished,, clamp mechanism 1 is unclamped by electric generation command adapted thereto, drive unit 3-1 work, freewheel clutch pinion 3-3 is in engagement, and rotates with tooth bar 4-3 engagement on one's own initiative, thereby drive whole lengthwise movement frame 3 and oppositely move correcting action.
