Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The manual ring folding device for the construction site comprises a bottom plate 6 for fixing, wherein an upright post 7 is welded in the middle of the bottom plate 6, and the lower part of the upright post 7 is provided with external threads for being in threaded connection with a cylindrical disc 1. The cylindrical disc 1 is a disc with a certain thickness, a hole is formed in the circle center of the cylindrical disc 1, and an internal thread is arranged in the hole and matched with an external thread on the lower portion of the stand column 7. The cylindrical disc 1 is a mould for folding a ring, and the diameter of the cylindrical disc 1 is the diameter of the ring formed by folding the steel strand or the thin steel bar later. For satisfying different demands, a plurality of can be made to cylinder dish 1, and different diameters are made according to the demand to these cylinder dish 1, satisfy not the ring requirement of rolling over of equidimension.

A sleeve column 2 is sleeved above the cylindrical disc 1, the sleeve column 2 can rotate around the upright post 7, a horizontal rotating rod 5 is welded on the side surface of the sleeve column 2, and a handle 8 is welded at the end of the rotating rod 5. Be equipped with a rectangular shape bolt hole 3 along the length direction of dwang 5 on dwang 5, be equipped with bolt 4 in the rectangular shape bolt hole 3, be equipped with nut 9 on the bolt 4, fix bolt 4 through nut 9. A compression leg 10 is welded at the lower part of the bolt 4. The long strip-shaped bolt holes 3 are used for adjusting the distance between the compression columns 10 and the side face of the cylindrical disc 1. The compression column 10 is in a cylindrical shape, the compression column 10 can be a stainless steel cylinder, and the compression column 10 is used for cooperating with the cylindrical disc 1 to bend and form a ring for the steel strand or the thin steel bar clamped therein. For guaranteeing that the circle effect of rolling over is better, this embodiment is preferred, compression leg 10 uses the bearing, and the bearing inner circle internal diameter of chooseing for use matches with 4 external diameters of bolt, with 4 lower parts of bolt insert the bearing inner circle in, then with 4 lower parts of bolt and the inner circle welding of bearing together, compression leg 10 is rolling over the circle in-process like this, and the outer lane of bearing can be pivoted, and the pivoted outer lane makes to roll over the circle effect better, constantly with wait to roll over the steel strand wires or the laminating of thin reinforcing bar of circle inseparabler.

When in use, the cylindrical disc 1 which conforms to the diameter of the ring to be folded is connected on the upright post 7 on the bottom plate 6 by screw threads, then the upper part is sleeved with the sleeve post 2 and the rotating rod 5, one end of the steel strand or the thin steel bar to be folded is placed on the side surface of the cylindrical disc 1 and is tightly attached to the side surface of the cylindrical disc 1, then the position of the bolt 4 is adjusted, so that the side surface of the pressing column 10 is tightly attached to the steel strand or the thin steel bar to be folded, namely, the steel strand or the thin steel bar to be folded is tightly clamped between the side surface of the cylindrical disc 1 and the side surface of the pressing column 10, then the bolt 4 is fixed by screwing the nut 9, a construction worker steps on the bottom plate 6 by feet, one hand is used for pressing the end of the steel strand or the thin steel bar to be folded, then the other hand rotates the handle 8, so that the rotating rod 5 rotates around the upright post 7, the steel strand or the thin steel bar to be folded is gradually folded into the ring in the rotating process, and the hand can change the pressing position of the steel strand or the steel bar in the ring folding process, so as to prevent the steel strand or the thin steel bar from tilting or running.

In order to make the ring folding process more convenient and reduce the force pressed by hands, as an optimal scheme, a plurality of identical circular threaded holes 11 are arranged on the cylindrical disc 1, a stop column 12 can be connected in the circular threaded holes 11 in a threaded manner, the distance between the circular threaded holes 11 and the side surface of the cylindrical disc 1 is very short, and a plurality of circular threaded holes 11 are arranged at a distance of about 0.5-2cm from the cylindrical discs 1 according to the cylindrical discs 1 with different diameters. During the use, after cylinder dish 1 has been selected, then select a circular screw hole 11 in the position of closing cylinder dish 1 side in turn, with bumping post 12 threaded fixation on the screw hole, then will wait to roll over the steel strand wires or thin steel bar one end of circle and put between bumping post 12 and cylinder dish 1, the hand is pressed the end and is regarded as supplementary, begins foretell circle folding operation, because the existence of bumping post 12, steel strand wires or thin steel bar one end are blocked, outside perk or the power of running have just been little a lot for construction worker can be more light the whole circle process of turning over of control.

Compared with the manual ring folding by using tools such as hands or a wrench, the ring folding device is easier, more convenient and faster, and the folded ring is a standard circle, so that the effect is greatly improved. The invention is not only used for bending the steel strand or thin steel bar, but also can be used for bending materials which can be bent by a spanner or a hand.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
