Abstract
A carbon arc air gouging device used for narrow gap thick plate deep groove metal removal comprises a handle and a spray gun, which is characterized in that the spray gun provided with a handle comprises a carbon rod, an ejector pin component, an inner casing, an outer casing, a nozzle casing and a nozzle. The outer casing is connected to the top of the inner casing through the folding edge of the top of the outer casing. A carbon rod is arranged in the centre of the inner casing. The ejector pin component is installed on the top of the outer casing between the carbon rod and the handle. The outer casing is connected to the nozzle casing through the folding edge of the outer casing side. A nozzle is arranged on the lower part of the nozzle casing and the outer casing. Four spray holes are arranged along the circumferential direction of the nozzle. The advantages of the utility model is that the structure is simple and compact, so that the utility model can be moved easily in the narrow gap and deep groove and the angle is adjustable. The corresponding repair can be implemented according to the different states of welding defects. The welding surface after the gas shaving is smooth and tidy, which is favourable for the smooth progress of the welding and provides a good condition for the welding seam repair.
Description
Technical field
The utility model relates to a kind of machine tool, specifically relates to the narrow gap of a kind of steel plate deep groove and removes metal carbon arc air gouging torch.
Background technology
In the manufacturing of thick-walled pressure vessel, the link of most critical is welding.Generally speaking, the steel plate of big thickness all adopts narrow gap groove type, and purpose is to reduce the residual stress that caused by welding, saves welding material.In the middle of the welding of narrow gap deep groove, most defective such as crackle, the slag inclusion that exceeds standard, pore etc. do not allow to exist.In case these defectives in welding process, occur, just must remove, and the common method that adopts have machining process and hot-working method.Machining process generally includes the emery wheel reconditioning, methods such as special purpose machine tool processing.Owing to limit by the condition of equipment own, adopt mechanical means can not reach effect convenient, fast, high-quality for dark and narrow groove.Hot-working method has carbon arc air gouging, electric arc to dig to cut etc.Carbon arc air gouging is meant to use carbon-point or graphite rod and be cut intermetallic generation electric arc and produces high heat energy and deposite metal, with compressed air the deposite metal is blown down, and reaches the purpose to metal surface processing.Adopt common carbon arc air gouging that thin plate is used effect is preferably arranged, for the narrow gap of big thick plates deep groove then since air-flow can not effectively reach the groove root and molten metal can not be blown away, make reprocessing of weld defect become very difficult, influence result of use.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly weld seam is reprocessed become the narrow gap of steel plate convenient, fast, high-quality deep groove to remove metal carbon arc air gouging torch.
The technical scheme that adopts is:
The narrow gap of steel plate deep groove is removed metal carbon arc air gouging torch, comprise handle, spray gun, it is characterized in that: spray gun is equipped with handle, spray gun comprises carbon-point, push rod component, inner sleeve, outer tube, nozzle casing, nozzle, outer tube is connected with the top of inner sleeve by the flanging at outer tube top, be provided with carbon-point in the middle of the inner sleeve, outer tube top between carbon-point and handle is equipped with push rod component, outer tube is connected with nozzle casing by the flanging of outer tube side, the bottom of nozzle casing and outer tube is provided with nozzle, and nozzle along the circumferential direction is provided with 4 spray orifices;
Above-mentioned handle comprises air inlet pipe, air inlet ozzle, control valve, gum sleeve, power lead, and air inlet pipe is provided with the air inlet ozzle, and control valve, power lead are installed, and the air inlet ozzle is equipped with gum sleeve, and handle is provided with insulating outer layer;
Above-mentioned push rod component comprises push rod, riser, and the handle upper surface of close carbon-point is equipped with riser, between riser and the carbon-point push rod is installed, and push rod is provided with spring.
During work, compressed air enters in the handle by rubber hose, and for guaranteeing enough gas flows, the internal diameter of handle and rubber hose is φ 14.On the air inlet pipe of handle, establish a control valve, the supply of control gas, and can adjust flow according to different instructions for uses.Gas by control valve enters into the air chamber inside that is made of inner sleeve, outer tube and nozzle casing, is concentrated by the nozzle place to eject again.The aperture of jet is less than air chamber, along the circumferential direction evenly distributes in injection place and bores 4 apertures that diameter is 1mm, guarantees the power of blowing uniformly when making the air-flow ejection.The nozzle casing material is a nylon; its objective is in order to insulate and solar heat protection; nozzle casing is deep into groove is inner the situation of power supply short circuit can not occur with the both sides Metal Contact; effectively protection groove and gouging torch can not destroy because of power supply short circuit when work; and compressed air can directly be concentrated and affact on the deposite metal, and the metal of thawing can be blown down easily fully.Pressure is 0.3-0.5Mpa. when pneumatically operated.
Advantage of the present utility model is: decoration structure features simple design, small and exquisite, can in the deep groove of narrow gap, move easily and the adjustment angle, and can repair accordingly according to different weld defect states.Face of weld behind the gouge is smooth, neat, and what help welding carries out smoothly, reprocesses the condition that provides good to weld seam.
