Description
Technical field: the utility model relates to a kind of utility of installation, maintenance heat exchange container pipeline, exactly is the outer casing knife of a kind of automatic plate.
Background technology: the pipeline installation, maintenance in the existing present heat exchange container needs the staff to enter in the container, change with new pipe with the sawed-off taking-up of metal tube that electronic abrasive cutoff saw or coping saw will be changed, so not only labour intensity is big, and time-consuming and poor stability, noise are big.I am in the Chinese patent ZL95211047.4 of application on May 16 nineteen ninety-five, disclosed the utility model patent of a kind of quick inner pipe cutter by name, its technical scheme is by cutter hub, rotating mechanism and be placed in its outer overcoat that is encapsulated in terminal surface by bearing cap and form, it is characterized in that: described cutter hub is by playing a knife bar, being loaded on the return spring in the knife bar end bottom circular aperture and being made up of the cutter head of fastening its front end of screw; Described rotating mechanism is made up of axis, return spring, depression bar cover and apical axis, axis has and the groove that plays the knife bar coupling, bearing, depression bar cover are placed in the rear portion, have a circular hole forward from terminal surface, adorn a return spring in it, the apical axis roof pressure is in the return spring end, and dog screw passes the depression bar cover, axis is fixed on the apical axis; Its endoporus of overcoat that is drum shape is two cylinders of pre-small post-large same central shaft, front end be with outward a swivel nut and with the locking nut of its coupling.Its advantage is to need not the staff to enter operation Pipe Cutting in the container, and safe and reliable, noise is little; Because be to adopt electronic cutting, speed is fast, work efficiency is high.But also there is defective in above-mentioned technology, when practical operation, because the external diameter that plays knife bar is less than the internal diameter that is cut pipe, and the vibration that produces of motor, the operator is difficult to make knife bar and to be cut tube side consistent to remaining, cause the cut surface injustice thus, tube wall is wearing and tearing easily also, stay accident potential, and the operator is when cutting, need firmly to head on casing knife so that cutter head lifts, labour intensity is also very big always.
Summary of the invention: the purpose of this utility model exactly in order addressing the above problem, to provide that a kind of speed is fast, time saving and energy saving, work efficiency is high, and can not damage the outer casing knife of automatic plate of tube wall.
Technical solution of the present utility model is: the outer casing knife of automatic plate, comprise centration axis, positioning sleeve, screw, cutter head, knife bar, splicing sleeve, pin, bearing, spring, overcoat, last item, end parts such as a screw, draw ring, main shaft, coupling spindle, cutter head is anchored on the knife bar front end by screw, main shaft has the groove with the knife bar coupling, knife bar is fixed in the main shaft by pin, tail end has spring, main shaft is located by bearing, be loaded in splicing sleeve and the overcoat inner chamber, it is characterized in that: the centration axis of front-end of spindle is with positioning sleeve outward; Last item is arranged in the circular hole of main shaft end, and front end is a wedge, joins with knife bar, and its terminal surface has a circular hole forward, built-in spring, and the coupling spindle roof pressure is in spring end; Draw ring is enclosed within on main shaft end " L " v notch v, and is fixed on the last item by ending a screw.
Compare with original technology, the positioning sleeve structure that the utility model adopts both can make the cutter head held stationary rotate, and can protect tube wall again.Last item is blocked at draw ring is positioned at " L " v notch v when the knife bar level " " end place, makes the spring in the last item be in compressive state.During use front-end of spindle is inserted in the pipe, the rear end is connected with the electric drill main shaft, rotates draw ring again, discharges last item, under spring action, and the last item reach, its wedge front end is depressed the knife bar tail end, and the cutter head perk begins to cut pipe.After cutting is finished, again draw ring is retracted " _ " end place of " L " v notch v, the compression spring, the effect of the spring of knife bar below afterbody is the rehydration level state next time, and the operator only needs electric hand drill to get final product from start to finish, and is very laborsaving.
The beneficial effects of the utility model are that cutting speed is fast, time saving and energy saving, work efficiency is high, and can not damage tube wall.
