The present invention relates to a channel bending device capable of easily bending a 'c' shaped steel, that is, a channel, to a size and curvature radius desired by a user without wrinkles or unnecessary deformation.

In general, the shaped steel is a rolled steel material having a constant cross-section. According to the shape of the cross-section, a 'b' angle, a 'h' beam, a 't' beam, and a 'c' channel are formed. have.

Unlike the form steel, which is used in civil engineering or construction parts, when used as a frame for forming interior or exterior materials or exterior of automobiles or home appliances, the shaped steel is used in a small size. In general, the section steel, which is used as a frame of home appliances, is mainly used as a channel of the ㄷ -shaped channel. The official name of this channel is the channel, but it is also called the channel.

When the channel is used as a frame forming the external appearance of home appliances, the external appearance may be curved rather than straight, or bent at many points. In order to bend such a channel, a conventional bending has been performed using a press die and a bending machine, and there is no specialized device for only the channel bending.

As a result, press molds used in conventional channel bending are expensive equipments in themselves, and thus, molds for each channel having various sizes and curvature radii must be manufactured, resulting in a huge increase in production cost. In addition, when bending a channel with a conventional general bending machine, there is a problem that a high quality bent channel can not be produced due to a large number of unnecessary deformations due to the 'c' opening or wrinkles.

An object of the present invention devised to solve the above problems is to provide a channel bending device that can be easily bent in the channel (channel) to the desired size and radius of curvature without wrinkles or unnecessary deformation.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the channel bending device according to the present invention.

The channel bending device according to the present invention is composed of a frame 100, a rotating shaft 110, a moving frame 120, a rotating frame 130 and a guide frame 140, as shown in Figure 1 to 9, bending It includes a roller 200, the support clamp 300, the rotary clamp 400 and the guide member 500.

As shown in FIGS. 1 to 4, the frame 100 is rotatably installed on the rotating shaft 110. The frame 100 must be firmly manufactured since various components to be described below are mounted and supported. The rotating shaft 110 is rotatably installed on the upper portion of the frame 100. The rotating shaft 110 is not shown in detail, but receives power from a forward and reverse rotation motor (not shown) to receive a reduction gear (not shown). It is decelerated through and receives the rotational force and rotates.

The bending roller 200 is mounted to the rotating shaft 110 as shown in Figures 1 to 4, the channel insert groove 210 is formed along the outer periphery so that the outer surface of the channel (C) to be bent is inserted and fixed do. The bending roller 200 is inserted into the rotating shaft 110 through the shaft through hole 201 through the rotation center, and rotates with the rotation of the rotating shaft 110. The bending roller 200 works with the support clamp 300 and the rotary clamp 400 to be described later as a main component for bending the channel C, and determines the radius of curvature of the channel C. That is, the bending radius of curvature of the channel C is determined according to the radius of the bending roller 200. In this case, the bending roller 200 is formed with a channel insert groove 210 to fix the channel C so that the channel C to be bent may be bent along the outer circumference of the bending roller 200. The channel insertion groove 210 is formed along the outer circumference of the bending roller 200, and the outer surface of the channel C is inserted and fixed. Therefore, the outer surface of the channel C inserted and fixed to the channel insertion groove 210 rotates with the rotation of the bending roller 200, and the radius of curvature is determined by the radius of the bending roller 200.

The moving frame 120, as shown in Figures 1 to 4 is installed on the upper portion of the frame 100 so as to be movable back and forth toward the bending roller 200. The moving frame 120 is linearly moved back and forth toward the bending roller 200 through the LM guide (not shown) on the upper portion of the frame 100, which is the support clamp 300 to be described later the moving frame 120 Is mounted on the moving frame 120 to move back and forth with.

As shown in FIGS. 1 to 4, the support clamp 300 is mounted to the movable frame 120 so as to be movable left and right along the longitudinal direction of the channel C, and is formed on the inner surface of the channel C. The support protrusion 310 is formed to protrude and press-fix the inner surface of the channel (C). Since the support clamp 300 is mounted on the moving frame 120, the support clamp 300 may move back and forth toward the bending roller 200 together with the moving frame 120, and may be left and right along the longitudinal direction of the channel C on the moving frame 120. I can move it. In other words, the support clamp 300 can be moved to the left and right linear movements separately from the front and rear linear movement by the movement of the moving frame 120 relative to the frame 100 and only the support clamp 300 based on the moving frame 120 separately. have. The front and rear linear movement of the support clamp 300 is a linear movement in the direction facing the inner surface of the channel C, that is, toward the bending roller 200, and the linear movement of the support clamp 300 in the left and right directions is performed on the channel C. Is a linear movement of the direction left and right along the longitudinal direction of the.

The support clamp 300 is for pressing and fixing the inner surface of the channel C in which the outer surface is inserted into the bending roller 200, and the support protrusion 310 is formed to protrude from the inner surface of the channel C. It is. That is, the support clamp 300 is mounted on the moving frame 120 and moved forward and backward together with the moving frame 120 as shown in FIG. 3, so that the support clamp 300 moves forward toward the bending roller 200 of the moving frame 120. 300 also moves forward and the support protrusion 310 formed on the support clamp 300 is fixed by pressing the inner surface of the channel (C). However, when the support clamp 300 does not move when the support clamp 300 is fixed while being bent during the rotation operation of the rotating clamp 400 and the bending roller 200, which is fixed to the support clamp 300, will be described later. C) may be tapered deformation. In order to minimize the left and right deformation along the longitudinal direction of the channel (C), the support clamp 300 is installed so as to be able to move to the left and right relative to the moving frame 120. That is, when the bending of the channel C, the support clamp 300 moves along with the direction in which the channel C rotates to prevent the deformation of the channel C from sagging.

The rotating frame 130 is installed to rotate together with the rotating shaft 110 as shown in FIGS. 1 to 4. Rotating frame 130 is installed separately from the frame 100, but is connected to the rotating shaft 110 is installed on the top of the frame 100 to rotate with the rotation of the rotating shaft 110 while sharing the center of rotation . The rotating clamp 400 to be described later is mounted on the rotating frame 130 to rotate together with the rotating frame 130.

1 and 4, the rotary clamp 400 is mounted to the rotating frame 130 so as to be movable back and forth toward the bending roller 200, and is arranged side by side with the support clamp 300. The rotation protrusion 410 is formed to protrude from the inner surface of the channel (C) protrudes to fix the inner surface of the channel (C) and at the same time rotates with the bending roller 200 to the channel (C) Bend

The rotary clamp 400 is mounted to the rotary frame 130, and moves back and forth toward the bending roller 200 based on the rotary frame 130. The rotary clamp 400 is arranged side by side with the support clamp 300 as shown in FIG. 3 when the support protrusion 310 of the support clamp 300 press-fixes the inner surface of the channel (C) Works. That is, the rotary clamp 400 is also formed by the rotation projection 410 is formed on the inner surface of the channel (C) protruding to pressure-fix the inner surface of the channel (C). However, unlike the support clamp 300, the rotary clamp 400 may rotate with the bending roller 200 as shown in FIG. 4 to bend the channel C. The bending roller 200 rotates together with the rotation shaft 110, the rotation frame 130 rotates together with the rotation of the rotation shaft 110, and the rotation clamp 400 mounted on the rotation frame 130 also rotates. Accordingly, the outer surface C is inserted into the bending roller 200 in the state in which the inner surface is pressed and fixed by the support protrusion 310 of the support clamp 300 and the rotation protrusion 310 of the rotary clamp 400. Is bent by the rotation operation of the bending roller 200 and the rotary clamp 400 in.

The bending work of the channel C may be performed only by the bending roller 200, the support clamp 300, and the rotary clamp 400. However, when the length of the channel C is long, the upper and lower twisted or deformed along the length direction during the bending process. This can happen. In order to prevent such vertical deformation, the guide frame 140 and the guide member 500 are installed to guide and support the portion except the bending point of the channel C along the bending direction.

That is, the bending operation of the channel C is inserted by inserting the outer surface to be inserted into the channel insertion groove 210 of the bending roller 200 and the guide groove 510 of the guide member 500. It is beginning. Of course, the specific operation of the bending operation is that the support protrusion 310 and the rotation protrusion 410 of the support clamp 300 and the rotary clamp 400 is fixed to the inner surface of the channel (C), respectively, the rotary clamp ( 400 and the bending roller 200 is to complete the bending of the channel (C) while rotating.

On the other hand, the size and radius of curvature of the channel (C) may also vary depending on the size or type of home appliances to which the panel (C) is to be installed. It should be possible to bend the channel C in accordance with the user's preference. Therefore, the bending roller 200, the support clamp 300, the rotary clamp 400 and the guide member 500 should be prepared in advance and provided in plurality according to the size and curvature radius of the channel C to be bent, respectively. . In addition, as shown in Figure 2, the bending roller 200 is detachably coupled to the rotating shaft 110, the support clamp 300 is detachably coupled to the movable frame 120, the rotation The clamp 400 is detachably coupled to the rotation frame 130, and the guide member 500 should also be detachably coupled to the guide frame 140. Accordingly, the user can replace the bending roller 200, the support clamp 300, the rotary clamp 400 and the guide member 500, which are provided in plurality for each size and curvature radius of the channel C.

At this time, as shown in Figure 2, the bending roller 200 is inserted and fixed through the rotating shaft 110 is easy to replace, but the support clamp 300, the rotary clamp 400 and the guide member 500 easily removable It is a problem. However, as shown in FIG. 2, the convex portions P protruding from the moving frame 120, the rotating frame 130, and the guide frame 140, respectively, are formed, and the support clamp 300 and the rotation clamp 400 are respectively formed. And the guide member 500 may be adapted to the slide insertion method to form a groove (D) for each of the convex portion (P) to be easily removable.

Hereinafter, a preferred operation process of the channel bending device according to the present invention will be described with reference to FIGS. 5 to 9, but overlapping description thereof will be omitted.

As shown in FIG. 5, the support clamp 300 and the rotary clamp 400 are moved to the rear. At this time, the outer surface of the channel C to be bent is inserted into the channel insertion groove 210 of the bending roller 200 and the guide groove 510 of the guide member 500.

As shown in FIG. 6, the support clamp 300 and the rotary clamp 400 are moved forward. In this case, the support protrusion 310 of the support clamp 300 and the rotation protrusion 410 of the rotary clamp 400 press and fix the inner surface of the channel C.

As shown in FIG. 7, the channel C is bent while the bending roller 200 and the rotary clamp 400 rotate. At this time, the support clamp 300 prevents left and right deformation during bending of the channel (C) while moving left along the bending direction of the channel (C), the guide member 500 is the outer surface is inserted into the guide groove (510) Guide the channel (C) to prevent the vertical deformation of the channel (C).
