Abstract
A steel tube joint circular seam automatic cutting device comprises a supporting frame. One side of an annular cutting platform is hinged with the supporting frame and the other side thereof is connected with a lifting rod. An adjustable gyration platform is arranged between a supporting rod and a lifting rod. A guide wheel is connected with a cutter by a guide bracket. The invention has a simple structure, low manufacturing cost and simple working procedure in the process of using the cutting device, saves lots of labour and time for calculating tube joint intersection line and drawing lines, and only needs to draw the highest point and the lowest point at the two ends of the tube joint once. The cutting radius can be automatically adjusted according to the roundness of the tube joint in the automatic cutting process by the guide wheel. The annular cutting platform can be adjusted according to the included angle between the cutting platform and the axial line of the tube joint through the adjustable gyration platform. The tube orifice size and welding crevasse can be cut once. Thus, the production efficiency is improved. The cutting device is particularly suitable for the manufacture of steel tube arched bridge beam tube joint and on-site manufacture of bent tube and straight tube of pressure steel tube in medium and small-sized power stations.
Description
Technical field
The present invention relates to a kind of device that is used to cut steel pipe bend pipe joint annular seam, be applicable to the cutting of arch rib bend pipe circumferential weld and the middle-size and small-size Hydraulic and Hydro-Power Engineering penstock bend pipe or the straight tube circumferential weld of steel pipe arch bridge beam.
Background technology
The situation that the pipe pipe is handed in the industrial pipeline is more, the pipeline in the thermal power generating equipment particularly, diameter is many below 1 meter, hand cut after the many employings of the blanking cutting model setting-out of its intersection, then adopt three-dimension numerical controlled intersection-line cutting machine blanking for cutting stock precision and weldquality are demanding, but this kind apparatus value reaches hundreds of thousands RMB (as the similar devices device of Wuhan University's development), and weak point is not too to be fit to the middle-size and small-size Hydraulic and Hydro-Power Engineering penstock manufacturing of diameter of steel tube more than 1 meter.
Summary of the invention
Because three-dimension numerical controlled intersection-line cutting machine is applicable to that mainly diameter 1m following steel-tube intersection-line cutting and price are higher, the present invention has overcome these problems, for the automatic blanking of steel pipe arch bridge beam and middle-size and small-size Hydraulic and Hydro-Power Engineering penstock intersection provides a kind of joint annular seam automatic cutting device.It has changed the traditional handicraft route, becomes the developed curve blanking and once prepares into plane cutting blanking and groove.
The object of the present invention is achieved like this: a kind of steel tube joint annular seam automatic cutting device, comprise bracing frame, annular Cutting platform one side and bracing frame are hinged, opposite side is connected with elevating lever, adjustable revolving dial places between bracing frame and the elevating lever, directive wheel is connected with cutting machine by guiding trestle, and cutting machine moves on annular Cutting platform by guiding trestle, finishes cutting operation by cutting torch.
Steel tube joint annular seam automatic cutting device provided by the invention mainly is made of adjustable revolving dial, annular Cutting platform, cutting machine and lowering or hoisting gear etc., and is simple in structure, manufactures cost and only needs tens thousand of units.When this device uses. operation is simple, saves tube coupling intersection unfolding calculation and a large amount of line time and recruitment and only need once mark tube coupling two ends highs and lows; Can adjust the cutting radius automatically in circularity when cutting automatically by directive wheel according to tube coupling; All can adjust by adjustable revolving dial, annular Cutting platform according to the angle of cutting planes and tube coupling axis; . once cutting is about to mouth of pipe size and welds cut and finish, improved production efficiency, be particularly suitable for the manufacturing of steel pipe arch bridge beam tube coupling and the bend pipe of medium waterpower generator station penstock and the scene of straight tube and make, this device can be used for cutting diameter at the steel pipe below 5 meters.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that A among Fig. 1 is to view.
Fig. 3 is directive wheel of the present invention, guiding trestle part enlarged drawing.
The specific embodiment
The intersection at bend pipe tube coupling two ends is the oval curve that two sections and pipe axis tilt to obtain in the tangent theory in pipe two ends respectively in theory.The present invention designs according to this theory.The present invention includes bracing frame 1, annular Cutting platform 3 one sides and bracing frame 1 are hinged, and opposite side is connected with elevating lever 4, and adjustable revolving dial 2 places between bracing frame 1 and the elevating lever 4, and directive wheel 5 is connected with cutting machine 6 by guiding trestle 7.
When the present invention uses, steel pipe bend pipe tube coupling 8 places on the adjustable revolving dial 2, rotation supporting plate by adjustable revolving dial 2 can make steel pipe bend pipe tube coupling 8 rotate in horizontal plane so that find the tube coupling highs and lows accurately, can be rotated in vertical plane again to adjust the size of cutting planes and tube coupling axis angle β.Annular Cutting platform 3 is as the orbit of semi auto cutting machine, because annular Cutting platform 3 one sides and bracing frame 1 are hinged, opposite side is connected with elevating lever 4, also can adjust by the angle α to cutting planes and tube coupling axis in vertical plane by the action of elevating lever 4.Directive wheel 5 is adjusted the cutting radius automatically with being connected with cutting machine with maintenance cutting machine 6 circularity according to tube coupling when cutting automatically by the contact of Pipe Cutting joint inwall and by guiding trestle 7.
