Description

Portable pipe bender for heating coil pipe

Technical Field

The utility model relates to a crooked technical field of stick, section bar or pipe especially relates to a portable hickey for heating coil.

Background

Among a series of building heating facilities including floor heating, a large number of heating coils are used. Because the area of the heating coil is large, the heating coil cannot be pre-bent and then transported to a use site for installation, but can be installed only by bending and folding the edge on the site. And because the heating coil is formed by continuously bending a whole pipe, the heating coil is bent while laying the pipe instead of bending at a fixed position when being installed, and thus the existing pipe bending equipment cannot be used for bending the heating coil (which is too heavy).

The existing heating coil pipes are mostly made of pure copper pipes, so that the heating coil pipes are relatively soft, and constructors can finish bending by relying on hands of the constructors, and the labor is not wasted. Therefore, when in construction, the constructor does not need to use the pipe bender, but bends the pipe by hands by feeling. However, it is difficult to determine the degree of each bend, which leads to a series of problems, such as poor fluid flow due to the bends, and uneven spacing between the tubes due to uneven size of the bends.

The heating coil has very single bending, only two bending types are provided, one bending type is a 90-degree bend, the other bending type is a U-shaped bend, the curvature radius of all the 90-degree bends is the same, and the curvature radius of all the U-shaped bends is also the same.

Detailed Description

As shown in fig. 1-2, a portable pipe bender for a heating coil includes a single-arc pipe bender for bending the heating coil by 90 degrees, and a U-shaped pipe bender for bending the heating coil into a U-shape;

the single-arc pipe bender comprises a quarter arc-shaped shaping rod A11, extension rods A21 and an anti-deformation rod A31, wherein the extension rods A21 extend outwards from two ends of the shaping rod A11 respectively, and two ends of the anti-deformation rod A31 are fixedly connected with the extension rods A21 respectively; the curvature radius of the outer side of the deformation-preventing rod A31 is the same as that of the inner side of a 90-degree bend of the heating coil;

the extension rod is used for fixing conveniently. The shaping rod is too small, and no place is available for fixing the heating coil after the heating coil is wound on the shaping rod. The effect of preventing the pole that warp is just in order to avoid the design pole to take place to warp, and simultaneously when using, the position of here preventing the pole that warp is kept away from the design pole, and the messenger constructor is stepping on with the foot and is preventing that the pole that warp fixes.

The U-shaped pipe bender is in a bulb shape and comprises a three-quarter arc-shaped setting rod B12, two extension rods B22 which are parallel to each other and respectively fixedly connected with two ends of the setting rod B12, and a deformation-preventing rod B32 of which two ends are respectively fixedly connected with the extension rods B22; the radius of curvature of the outer side of the deformation preventing bar B32 is the same as the radius of curvature of the inner side of the U-shaped bend of the heating coil.

The reason why the U-shaped pipe bender is designed into bulb shape instead of U-shaped is that in practical use, we find that if the U-shaped pipe bender is designed into U-shape, the heating coil may not bend in place, and although the pure heating coil is soft, the heating coil has a slight rebound tendency to bend into U-shape, so that the bending amount must be increased.

The extension rod B22 and the shaping rod B12 are in smooth transition, and the distance between the two extension rods B22 is not more than 1.4 times of the radius of curvature of the inner side of the shaping rod B12. If the distance between the two extension bars B22 is too large, the heating coil cannot be bent in place.

The number of the deformation preventing rods B32 in each U-shaped pipe bender is not less than two. One is not enough to fix the shape of the sizing bar B.

The upper and lower surfaces of the deformation preventing rod A31 are aligned with the upper and lower surfaces of the shaping rod A11, and the upper and lower surfaces of the deformation preventing rod B32 are aligned with the upper and lower surfaces of the shaping rod B12. If not aligned, the anti-deformation bar may hang when stepped on, or cause the shaping bar to hang.

The shaping rod A11, the shaping rod B12, the extension rod A21, the extension rod B22, the deformation prevention rod A31 and the deformation prevention rod B32 are DN25 galvanized steel pipes, the shaping rod A11 and the extension rod A21 are integrally formed, the shaping rod B12 and the extension rod B22 are integrally formed, the deformation prevention rod A31 and the extension rod A21 are connected in a welded mode, and the deformation prevention rod B32 and the extension rod B22 are connected in a welded mode.

In the pipe bender, the welding seam is coated with anticorrosive paint, and the cut is smooth and burr-free polished surface and coated with anticorrosive paint. These locations are places that are prone to corrosion and therefore need to be protected.

The outer curvature radius is carved on the shaping rod A11 and the shaping rod B12, so that the identification by constructors is facilitated, and the turnover use is facilitated. The outer sides are as defined above and refer to the outer arc of an arc-like structure.

The utility model discloses a method of use includes following step:

the method comprises the following steps: the pipe bender is placed on the floor, and the deformation-proof rod is treaded by feet

Step two: and winding the heating coil pipe on the outer side of the shaping rod to finish bending.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
