Abstract

The utility model provides a hand pipe cutter used in the big caliber metal pipe whose diameter is larger than 100 millimeter. The utility model uses a cutter chain type link block with the circular cone blade strip teeth surface, and the link block is connected to form a movable periphery integrity which can press the external wall of the pipe tightly to roll to and fro under the action of moving a moving pole and rotating a cutter entering handle so as to reach the purpose of cutting the pipe by pressing and chipping. Meanwhile, the number of the link block can be increased or decreased according to the size of the caliber of the pipe in limitation. The utility model has the advantages of having simple structure and portability and lightness, and can be operated by one man without the limitation of the energy source and the environment to bring convenient to the cutting work of the pipe.

Description

Hand pipe cutter

What the utility model was related is pipelayer's pipe cutting instrument, and a kind of φ of being used for 100mm is provided the manual pipe cutting instrument of above heavy caliber metallic conduit cutting.

The people who does the pipeline installation knows, the hand hacksaw is adopted in the cutting that pipeline is installed more, electric welding, electronic pipe cutter, hydraulic pressure pipe cutter etc., the labour intensity that these method and apparatus have is big, time is long, what have is subjected to power limitations, particularly the hydraulic pressure pipe cutter is owing to be rigid extruding, run into the situation that pipe thickness is inhomogeneous or material is assorted, will cause pipeline breaking, and sealing system has leakage slightly, just lose the purpose that extruding force does not reach the cutting pipeline, at this problem, we are to retrieving about document both at home and abroad, still there is not preferable pipe cutting method, for this reason, we cut pipe cutter to the hand that everybody discloses the above heavy caliber metallic conduit cutting of a kind of φ 100mm, and it can not be subjected to the restriction of the energy under any environment and condition, be contained on the pipeline that to cut as long as this equipment enclosed, back and forth move moving rod and turn feed handle with hand, in ten minutes, pipeline can be cut off, use simple light and flexible, labour intensity is low, efficient height and otch are neat, because the compressive zone iron filings can not cause pipeline breaking, have obvious superiority, be applicable to the cutting of the above various metallic conduits of φ 100mm.

Structure of the present utility model further describes by the following drawings,

Fig. 1, manually the unitary construction figure of pipe cutter.

Fig. 2, delivering gear main body profile.

Fig. 3, the cutter profile.

Structure of the present utility model as shown in Figure 1, this device is made up of a plurality of contiguous blocks (8) and feed fixed block (5) and delivering gear main body (3), contiguous block (8) connects feed fixed block (5) and delivering gear main body, formation garden round forms the delivering gear main body of shape on the top of garden circle; Have a groove and pack a garden shape at the middle part of contiguous block (8), the cutter (9) of awl sword, the band flank of tooth, the part of cutter (9) is exposed outside the groove, cutter (9) is a garden shape, the awl sword is the flank of tooth in the back of awl sword, as shown in Figure 3, reveal the movable garden shape integral body of a part of cutter in constituting one.The delivering gear main body as shown in Figure 1, 2, be by feed handle (1), moving rod (2) feed screw rod (4), delivering gear body shaft Xiao (10), screw (11), caking (12), angular wheel shaft (13), bevel gear nut (14) is formed, this delivering gear main body is cooperated with umbrella teeth nut (14) by feed screw rod (4) and angular wheel shaft (13), and angular wheel shaft (13) is connected rotation by the long distance of moving rod (2) with feed handle (1).The conical surface of angular wheel shaft (13) and bevel gear nut (14) is 45 °.Fixed block is that strip entity middle part has groove and the elongate body of cutter (9) of can packing into, and there is connecting axle Xiao hole on both sides, and the cutter that exposes a part is housed in the medial launder, and cutter (9) as shown in Figure 3.The length of contiguous block (8) is the plus-minus size of different bore pipelines, simultaneously, can increase or reduce this contiguous block arbitrarily in limitation.Fixed block is that one end connects the angle body that contiguous block plays fixation by the end connection delivering gear main body of certain length size.

This manual pipe cutter course of work is by feed handle (1), moving rod (2) delivering gear main body (3), feed screw rod (4), feed fixed block (5) is connected by attachment screw (7) with the several piece contiguous block, it is characterized in that every contiguous block (8) middle part has groove and packs into by the fixing cutter of Xiao (6) of fixing cutter (9), and the part of cutter (9) is exposed outside the groove, but thereby smear metal, its contiguous block (8) can be added and subtracted arbitrarily in the limit according to the pipe diameter size, the length of contiguous block is the plus-minus size of different bore pipelines, the contiguous block (8) that connects, one end is connected with delivering gear main body (3), one end is connected with feed fixed block (5), delivering gear main body (3) is connected by screw rod (4) with feed fixed block (5), after cutter (9) compresses tube wall, move moving rod (2), the whole cutter (9) that drives of cutter pipe is cut along duct wall is back and forth mobile, when moving moving rod (2), rotation feed handle (1) makes angular wheel shaft (13) transmission bevel gear nut (14) and feed screw rod (4) realize feed, reaches the purpose of cutting off pipeline.

According to the pipe diameter size, after contiguous block (8) is linked to be required length, surround pipeline, with feed screw rod (4) delivering gear main body (3) is connected with feed fixed block (5), formation is to the shape that surrounds of pipeline, load onto moving rod (2), rotation feed handle (1) tightens up contiguous block (8), cutter (9) is pressed on the tube wall, move moving rod (2) again, make pipe cutter integral body be with cutter (9) on tube wall, back and forth to roll, rotate feed handle (1) feed simultaneously, like this as long as just pipeline can be cut off in ten minutes.

The utility model is simple in structure, but one man operation, and light and flexible is not subjected to the restriction of the energy and environmental condition, adapts to the above any bigbore pipe cutting work of φ 100mm and laborsaving saving time.
