Description
Technical field
the utility model relates to pipe machining equipment field, is specifically related to a kind of thin walled tube plug.
Background technique
Under prior art condition, if thin-walled tube bending is become various shape, because the internal stress of tubing is not enough, often make pipe deformations.So, full fine sand can be filled in pipe as last at bending thin walled tube, thus increase the internal stress of tubing, make tubing not yielding when bending.Carrying out in above-mentioned filling sand work, fine sand fills up after in tubing, and existing mode is clogged by the port of stopper by tubing two ends, and what adopt due to general stopper is all soft wood, just because distortion cannot use after often using 1-2 time, namely waste timber and turn increase the operating time.Moreover, easily pipe end is squeezed distortion when stopper blocks up tight, so size of pipe and tubing must be lengthened when bending, by two tip cut-offs of distortion after shaping, both waste tubing like this, add cost of parts, also add manufacturing procedure.
Model utility content
The purpose of this utility model be for solve above-mentioned in technical problem, provide a kind of use can not make thin walled tube port be out of shape and the thin walled tube plug of easy accessibility.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of thin walled tube plug, comprise upper plug head and lower end cap, it is characterized in that: described upper plug head and lower end cap are equipped with screw rod, screw rod bottom radial direction extends to form base plate, on described screw rod, cover has ring-shaped rubber, this ring-shaped rubber is placed in plate upper surface, and the outer annular diameter of this ring-shaped rubber is greater than base plate diameter, is less than the internal diameter of corresponding thin walled tube simultaneously; Described screw rod also overlaps above ring-shaped rubber top board, and this top board diameter is greater than corresponding OD of Thin Wall Welded Pipe; Described screw rod is also provided with nut above top board, to make ring-shaped rubber stretch into Guan Zhonghou by screw rod, is fixed between pressing plate and top board.
Described spiro rod length is 25mm-30mm, the height of described ring-shaped rubber is 20mm-25mm, its outer annular diameter is greater than described base plate diameter 0.5mm-1mm, the outer annular diameter of this ring-shaped rubber is less than the internal diameter 0.5mm-1mm of corresponding thin walled tube simultaneously, and described top board diameter is greater than corresponding OD of Thin Wall Welded Pipe 1mm-3mm.
What described ring-shaped rubber adopted is the better nitrile butadiene rubber of elasticity.
In described upper plug head, the upper end of screw rod is also connected with round handle, is convenient to extracting of after finishing using upper plug head.
Technique effect of the present utility model:
1, mounting or dismounting are convenient, can fast by the shutoff of thin walled tube two ends, and pipe end can not be made to be out of shape;
2, ring-shaped rubber not fragile and distortion relative to stopper, can repeatedly and Long-Time Service.
Accompanying drawing explanation
Fig. 1 is using state figure of the present utility model;
Illustrate: 1, upper plug head 2, lower end cap 3, screw rod 4, pressing plate 5, ring-shaped rubber 6, top board 7, nut 8, circle handle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Thin walled tube plug using state figure as shown in Figure 1, upper plug head (1) and lower end cap (2) are installed in the two ends of thin walled tube, and the two structure is close, and namely both are equipped with screw rod (3), this screw rod (3) length is 25mm-30mm, and screw rod (3) bottom radial direction extends to form base plate.The upper cover of screw rod (3) has the ring-shaped rubber (5) be made up of the better nitrile butadiene rubber of elasticity, this ring-shaped rubber (5) is highly 20mm-25mm, be placed in plate upper surface, namely accept and base plate upper end, this ring-shaped rubber (5) outer annular diameter is greater than described base plate diameter 0.5mm-1mm, and its outer annular diameter is less than the internal diameter 0.5mm-1mm of corresponding thin walled tube simultaneously; Screw rod (3) also overlaps in ring-shaped rubber (5) top top board (6), this top board (6) diameter is greater than corresponding OD of Thin Wall Welded Pipe 1mm-3mm, screw rod (3) is also provided with nut (7) in top board (6) top simultaneously, to make ring-shaped rubber (5) stretch into Guan Zhonghou by screw rod (3), be fixed between pressing plate (4) and top board (6).Meanwhile, for making upper plug head (1) the extracting of upper plug head (1) after finishing using, in described upper plug head (1), the upper end of screw rod (3) is also connected with round handle (8).
During use, the ring-shaped rubber (5) of lower end cap (2) is loaded screw rod (3) upper and under push away in screw rod (3) lower end, and equally top board (6) and nut (7) are arranged on screw rod (3) according to the order of sequence, then screw rod (3) lower end is stretched in thin walled tube lower end mouth, until top board (6) stops by thin walled tube lower end mouth edge, now nut (7) is tightened, while tightening, the two ends pressurized of ring-shaped rubber (5), and make ring-shaped rubber (5) radial dilatation, by complete for lower end mouth shutoff, and what adopt due to ring-shaped rubber (5) is the good nitrile butadiene rubber of elasticity, hardness and intensity are much smaller than the tube wall of thin walled tube, thin-walled pipe end can't be made to be out of shape.After lower end cap (2) installs, poured into until distance upper end-hole 20mm-25mm from thin walled tube upper end-hole by fine sand, upper plug head (1) is arranged on thin walled tube upper end by the mounting type repeating lower end cap (2).After installing, thin walled tube is filled with fine sand and comparatively consolidation, adds the internal stress of thin walled tube, can carry out bending smoothly.After machining, the nut (7) of counterrotating upper plug head (1), nut (7) is unclamped, now ring-shaped rubber (5) is not squeezed and reinstatement because of upper and lower two ends, upper plug head (1) can be taken out smoothly, after the fine sand evacuation in thin walled tube, repeat the dismounting action of upper plug head (1), the lower end cap (2) of thin walled tube lower end is removed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
