Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view schematically showing the configuration of the bending device according to the present invention.

Referring to the drawings, the bending apparatus according to the present invention includes a main body 100, a base plate 10 installed on the main body 100, and a plurality of through holes 11 formed on the base plate 10. A plurality of sliding members (20) provided to be transported to the support), a rotating member (30) rotatably installed on the sliding member (20) to support a material to be bent, and the rotating member (30) is a sliding member. Sagging prevention means installed in the 20 to maintain the rotation and position, and connected to the rotating member 30 and the sliding member 20 to return the position of the rotating member 30 after the bending operation The installed spring 40 and the sliding means 20 is provided orthogonal to the sliding means 20 is provided with a transfer means for providing a transfer force to enable the position transfer of the sliding member 20.

The configurations thus made form the bottom of the bending device according to the invention.

And the bending apparatus which concerns on this invention is provided in the upper part of the main body 100, The upper mold | type 50 which defines the shape and angle of the bending part of a raw material, and one side of the main body 100 so that this upper mold | type 50 can be lifted up and down. It is configured to include a hydraulic means installed to provide a hydraulic force.

The sag prevention means includes a bolt 21 coupled to the lower end of the rotating member 30 and the upper portion of the sliding member 20 to rotate the rotating member 30 on the sliding member 20. . This bolt 21, however, is merely one embodiment of the present deflection prevention means, but is not limited thereto.

The conveying means is connected to the sliding member 20 and provided with a screw 61 for transferring the sliding member 20, and a handle 62 provided at one end of the screw 61 to rotate the screw 61. It is configured to include).

In addition, a support member 63 for supporting the screw 61 on the base plate 10 is installed at one end of the screw 61 on one side of the handle 62. The screw 61 is formed of a square screw, for example, a square right screw. Similarly, the conveying means is not limited to the present invention by the above embodiment.

And the upper die 50, the die according to the bending shape of the material, for example, as shown in Fig. 2 and 3, the circular blade 71 and the fastening groove 73 for fastening the V-shaped blade 72 is The mold blades 71 and 72 are fastened to a fastening groove 73 by a fastening member, for example, a bolt 74.

In addition, the hydraulic means, the hydraulic cylinder 81 is installed on the upper portion of the main body 100, that is, the upper portion of the upper mold 50, and, for example, to provide an operating force to the hydraulic cylinder, for example, It is composed of a hydraulic pump (not shown) installed therein, and a control panel 82 for controlling it.

Although not shown in the figure, a plurality of semicircular grooved rotary plates for circulating grooves are installed in order to bend pipes at the position where the rotary member 30 is mounted.

Meanwhile, reference numeral 91, which is not described in FIG. 2, is an operation switch for operating the hydraulic cylinder 81, 92 is a fixing bolt for fixing the desired position after the sliding member 20 is transferred, 93 is a ruler It is shown.

Referring to the operation of the bending device according to the present invention having the configuration as described above are as follows.

Referring back to the drawings, the bending device according to the present invention, after moving the position of the lower mold transfer structure consisting of the rotating member 30 and the sliding member 20 with the screw 61 so that the desired product can be manufactured , The sliding member 20 is fixed using the fixing bolt 92.

Then, the bending material is placed on the rotating member 30, and the upper mold 50 fixed to the hydraulic cylinder is slowly lowered, and the material is bent between the upper mold 50 and the lower mold. Bending round.

In addition, when the upper mold 50 rises and collides with the product, the rotation member 30 is restored to the original state by the spring 40 so that the material can be set again.

In order to bend the pipes, a semicircular groove-shaped circular plate with a circular groove, for example, is assembled on the rotating member 30 by using a bolt, whereby the material can be restrained and the work can be smoothed.

4a and 4b schematically show a process diagram for working with the bending device according to the invention.

Referring to the drawings, first, for example, when the U-shaped bending, the upper mold 50 is replaced according to the round size, and the handle 62 is rotated to adjust the distance of the sliding member 20 to the round size. This is the same as meaning that the distance of the rotating member 30.

Then, a material, for example, steel plate 101 is placed on the rotating member 30, and the upper mold 50 is operated to press. At this time, the angle is changed by adjusting the pressing height.

On the other hand, when the V-type bending, it is replaced by the V-shaped blade as shown in Figure 2 to work in the same way as described above.

As described above, the bending device according to the present invention has the following effects.

Since the position of the rotating member of the dedicated bending device can be freely changed, regardless of the size or shape of the bending part, it is possible to manufacture several products of various shapes in one dedicated bending device, and can be avoided by manual work as in the prior art.

Therefore, there is no need to manufacture a separate mold for each product, the production period is shortened, and the cost required can be reduced by reducing the number of people required to produce the product.

It is also possible to bend not only plate materials but also pipes and other materials.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
