The utility model is structurally characterized in that: the reamer body is composed of several reamer sections gradually decreasing in diameter, and each reamer section is axially provided with several concave reamer grooves; cutting edges are opened on the reamer grooves; the reamer sections present crown face between each two reamer grooves; a concave annular groove is provided in a radial direction among the reamer sections and between the reamer body and the reamer bar. The utility model has the advantages of: simply structured, convenient in use, applicable to composite pipes of a plurality of specifications.
Description
Technical field
The utility model relates to a kind of reaming reamer, especially a kind of reaming reamer that has the full circle function that is applied in the multiple tube installing engineering.
Background technology
Plastic composite pipe is high-tech environment-friendly products of new generation, has characteristics such as in light weight, easy installation, life-span be long, has been widely used at present in the hot water pipe, gas pipe, solar water organ pipe of upper hose, the Civil apartment of water engineering.In installation process, need two identical bodys of caliber be connected together by pipe joint, need during operation to carry out full circle with the rounding device line up earlier, with scraper it is carried out chamfering again; Or carry out full circle and chamfering with the dedicated tool line up.The former need use two kinds of instruments simultaneously when operation, operation inconvenience; The latter's dedicated tool can only carry out full circle and chamfering to a kind of body of specification, and the scope of application is little.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use, reaming reamer that has the full circle function of can be applicable to multiple different size multiple tube.
The technical scheme in the invention for solving the above technical problem is: this reamer comprises holds body, knife bar and cutter hub, holding body links to each other with knife bar, knife bar and cutter hub are structure as a whole, its design feature is that described cutter hub is made up of several diameters differences and gradually little piecemeal cutter hub section, each cutter hub section is provided with the cutter groove of some indents in the axial direction, have cutting edge on the cutter groove, the cutter hub section is arc surface between each cutter groove; Between each cutter hub section, be provided with the cannelure of indent between cutter hub and the knife bar diametrically.
The cross section of cutter groove described in the utility model is L shaped.
The two ends of cutter hub section described in the utility model are provided with chamfering.
Duan Weisan to five section of cutter hub described in the utility model, described cutter groove are three to five.
Have screw rod on the knife bar described in the utility model, hold body and link together by screw rod and knife bar.
The utility model compared with prior art, have following beneficial effect: 1, cutter hub is made up of several diameters differences and gradually little piecemeal cutter hub section, simple in structure, can be applied to multiple different size multiple tube simultaneously, need not before the use to select round rod, and hold body portion comfortable feel, gripping conveniently according to the body specification; 2, have some arc surfaces on the knife bar, can be used for mouth of pipe full circle, have indent cutter groove on the knife bar simultaneously, can be used for mouth of pipe chamfering, make this reamer have full circle and chamfering function simultaneously; 3, hold between body and the cutter hub by screw rod and connect, be convenient to dismounting, easy to process.

Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the stereogram of the utility model embodiment.
The specific embodiment
Referring to Fig. 1～Fig. 3, present embodiment comprises holds body 1, knife bar 2 and cutter hub 3, holds to have screw rod 7 on the body 1, holds in the body 1 and is provided with screw thread, holds body 1 and is threaded togather with knife bar 2.Knife bar 2 and cutter hub 3 are structure as a whole, cutter hub 3 is made up of three diameters differences and gradually little piecemeal cutter hub section 4, it is L shaped indent cutter groove 5 that each cutter hub section 4 is provided with four cross sections in the axial direction, has cutting edge on the cutter groove 5, and cutter hub section 4 is arc surface 9 between each indent cutter groove 5; Between each cutter hub section 4, be provided with the cannelure 6 of indent between cutter hub 3 and the knife bar 2 diametrically.The two ends of each cutter hub section 4 are provided with chamfering 8.
Three cutter hub sections 4 are applicable to the multiple tube of three kinds of regular sizes respectively.
The material of holding body 1 is plastics, and the material of knife bar 2 and cutter hub 3 is a steel.
During use, because cutter hub 2 is provided with the cutter hub section 4 of three kinds of diameter, so multiple tube applicable to three kinds of specifications, cutter hub section 4 is screwed in the mouth of pipe of multiple tube, when being threaded to the end, can carry out full circle, carry out chamfering by the cutting edge line up on the cutter groove 5 by arc surface 9 line ups, cutter groove 5 and cannelure 6 can be used for dust lead.
When needing dismounting, only need to hold body 1 and knife bar 2 and come from screw rod 7 dismountings and get final product.
