Abstract
The utility model discloses a metal pipe convex ring form-cutter, which comprises a tubular holder, a reciprocate turn-screw arranged in the holder, a hand grip on the upper portion of the turn-screw. Wherein, a gag lever post which is protruded out of the holder is fastened on the lower portion of the turn-screw, and a convex rolling wheel is arranged on the front end of the gag lever post. A concave rolling wheel is arranged on a lower portion corresponding to the convex rolling wheel of the lower portion of the holder. The designhas the advantages of simple structure, convenient and easy operation, and avoidance of damaging of the pipe body, deduces the cost of the materials of metal pipes and cuts the cost of the pipes.
Description
Technical field
The utility model relates to the shaping jig that metal pipe material is tightly connected and uses.
Background technology
Traditional metal tube connected mode, adopt is threaded or the plough groove type connection more, these connections must be carried out machining to the port of tubing, thereby destroy, weaken the intensity of pipe end, for this reason, tubing will be reserved allowance when producing, the wall thickness of tubing is greatly increased, and has wasted a large amount of metal materials.The bulge loop pipe fitting connects the wall thickness that then can effectively reduce tubing, and protection body port intensity reduces cost.How form bulge loop in the tubing end, and do not damage body, this patent will solve just.
The utility model content
The purpose of this utility model is the metal tube bulge loop shaping jig that proposes a kind of simple in structure, processing ease, do not damage body.
The technical solution of the utility model is: a kind of metal tube bulge loop shaping jig, include the tubular support, be loaded on the handgrip on turn-screw moving up and down, leading screw top in the support, the bottom of leading screw is fixed with gag lever post, gag lever post stretches out in outside the support, and the gag lever post front end is equipped with a protruding roller; Recessed roller is equipped with in the below of the corresponding protruding roller in the bottom of support.Further, recessed roller is a pair of, and they become " product " font to be arranged on the same plane with protruding roller.
During moulding, the metal tube port is inserted protruding roller, until being adjacent to support, rotating handgrip compresses leading screw downwards, until tube wall being sandwiched between protruding roller and the recessed roller, swinging mounting screws leading screw simultaneously gradually then, utilizes leading screw pressure to make the metal tube tube wall form the bulge loop of warp-wise protuberance.Such design, it is simply easy to have a moulding, does not damage advantages such as tubing, guarantees pipe port intensity, and makes the tubing of producing need not reserve allowance, and wall thickness significantly reduces, and reduces the tubing production cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.
The specific embodiment
Referring to Fig. 1-Fig. 2, the shaping jig of present embodiment is a hand-operated tools of making metal bulge loop pipe, is made of tubular support 4, leading screw 1, handgrip 5, gag lever post 7, protruding roller 2, recessed roller 3, leading screw chute 6 etc.Leading screw 1 is loaded in the support 4, rotate 5 by upper hand, and can move up and down along leading screw chute 6, the bottom of leading screw 1 is fixed with gag lever post 7, gag lever post 7 passes leading screw chute 6 and stretches out in outside the support 4, a protruding roller 2 is equipped with in its end, and same plane, below " product " font of the corresponding protruding roller 2 in the bottom of support 4 is furnished with two recessed rollers 3.During processing tubing, tubing 8 ports are packed into protruding roller 2, be adjacent to support 4, turn leading screw handgrip 5, be fixed on after protruding roller 2 on the leading screw 1 promotes tubing 8 and compress concave-concave roller 3, swinging mounting 4 makes pipe convex roller 2 and the outer concave-concave roller 3 of pipe rotate around tubing 8, swinging mounting 1 screws leading screw handgrip 5 simultaneously gradually, increase 2 pairs of tubing of protruding roller, 8 inwall roof pressure power, when gag lever post 7 was adjacent to tubing 8 inwalls, tubing 8 ports promptly formed the radially bulge loop 9 of protuberance, and counter-rotating leading screw handgrip 5 unclamps protruding roller 2, withdraw from tubing 8, machine.
Tubing 8 is by behind the shaping jig moulding bulge loop 9, not only can not destroy pipe port, and tube wall improves resistance to compression, the tensile strength of pipe end greatly by prolonging pressure energy, the more important thing is and to make the wall thickness of tubing when producing to reserve allowance, save metal materials in a large number, reduce the cost of tube connector greatly.
Certainly, only enumerated a kind of preferred implementation here, the protection domain that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
Claims (2)
1, a kind of metal tube bulge loop shaping jig, include the tubular support, be loaded on the handgrip on turn-screw moving up and down, leading screw top in the support, it is characterized in that: the bottom of leading screw is fixed with gag lever post, gag lever post stretches out in outside the support, and the gag lever post front end is equipped with a protruding roller; Recessed roller is equipped with in the below of the corresponding protruding roller in the bottom of support.
2, bulge loop shaping jig according to claim 1 is characterized in that recessed roller is a pair of, and they become " product " font to be arranged on the same plane with protruding roller.
