Technical Field

[0001] The utility model generally relates to the technical field of pressure vessel design, and in particular to a channel steel bending device. Background Art

[0002] With the rapid development of my country's national economy, chemical products have been applied to all aspects of people's lives. Due to the wide variety and complexity of chemical products, pressure vessels, as the basic equipment for the production of chemical products, need to use different manufacturing processes to meet product needs according to the different products produced.

[0003] During the manufacturing process of pressure vessels, tower containers are mostly chemical containers, which are over 100 meters high. They are generally manufactured in sections and assembled on site. Each section of the tower manufactured in sections is about 30 meters, and most of them are thin-walled Class I and Class II containers. The straightness and ovality of tower containers are directly related to the ability to resist wind loads. Therefore, using channel steel rings as cylinder reinforcement rings to improve the performance of thin-walled containers has become one of the main control indicators of tower containers. The control of the straightness and ovality of tower container manufacturing is the key point of the manufacturing process and runs through the entire manufacturing process.

[0004] Therefore, there is an urgent need for a channel steel bending device to reduce the resource and equipment limitations brought about by the traditional channel steel bending method, making the production of channel steel rings simpler and more convenient. Utility Model Content

[0013] like Figure 1 and Figure 2 As shown, the utility model provides a channel steel bending device. The device includes a three-roller plate rolling machine 5, which is equipped with a driving roller 9 and two driven rollers 10, and the three rollers are arranged in a triangle. Figure 1 As shown, the surface of the active roller 9 is sequentially sleeved with a first flange 2, a second flange 3, a third flange 7 and a fourth flange 8. The first flange 2 and the second flange 3 are configured as a group, and the third flange 7 and the fourth flange 8 are configured as a group. The first flange 2, the second flange 3, the third flange 7 and the fourth flange 8 are of the same model. The device also includes a positioning device and a channel steel 4. Figure 2 As shown, the channel steel 4 is arranged between the active roller 9 and the driven roller 10, and the channel steel 4 is bent into shape by the cooperation between the active roller 9 and the driven roller 10. Figure 1 The positioning device includes a flange positioning block 1, which is respectively arranged on the side of the first flange 2 and the second flange 3, the third flange 7 and the fourth flange 8 that are away from each other, and the flange positioning block 1 fixes the first flange 2, the second flange 3, the third flange 7 and the fourth flange 8 to the surface of the active roller 9 by bolt fixing.

[0014] In a preferred embodiment, Figure 2 As shown, first install the channel steel 4 between the driven roller 10 and the active roller 9, and adjust the spacing between the second flange 3 and the fourth flange 8 to position the total width of the channel steel 4. The second flange 3 and the fourth flange 8 are fixed to the surface of the active roller 9 by bolts through the flange positioning block 1, thereby fixing the relative positions of the third flange 7 and the fourth flange 8, which avoids the deviation of the channel steel 4. Next, start the three-roller plate rolling machine 5, so that the active roller 9 starts to rotate. Driven by the active roller 9, the channel steel 4 will move to the side of the active roller 9, and at the same time, the two driven rollers 10 are squeezed and matched with the active roller 9, and finally the channel steel 4 is bent into shape. This bending method reduces the resource and equipment limitations brought about by the traditional bending method, making the production of the four rings of the channel steel easier.

[0015] In another preferred embodiment, Figure 1 and Figure 3As shown, the channel steel 4 is in a "U" shape, and the two short arm ends of the channel steel 4 are respectively arranged between the first flange 2 and the second flange 3, the third flange 7 and the fourth flange 8. Specifically, as mentioned above, after the total width of the channel steel 4 is positioned by the second flange 7 and the fourth flange 8, the first flange 2 and the third flange 7 are adjusted so that they fit on the inner walls of the two short arm ends of the "U"-shaped channel steel 4. Similar to the fixing method of the second flange 3 and the fourth flange 8, the first flange 2 and the third flange 7 are also positioned and fixed by the flange positioning block 1, which avoids deformation of the two short arm ends of the channel steel 4 when the channel steel 4 is bent.

[0016] In another preferred embodiment, Figure 1 and Figure 3 As shown, the height of the two short arm ends of the channel steel 4 is h1, the thickness of the two short arm ends of the channel steel 4 is h2, the total length of the channel steel 4 is h3, and the total width of the channel steel 4 is h4. The dimensions h1, h2, h3 and h4 of the channel steel 4 are measured by a measuring device. The surfaces of the first flange 2 and the second flange 3, the third flange 7 and the fourth flange 8 are respectively movably mounted with a portable level 6. The measuring device can be one of a box measure and a tape measure, which is used to pre-measure the dimensions h1, h2, h3 and h4 of the channel steel so as to select the range and specification of the three-roller plate rolling machine 5. Specifically, based on h1, the height of the active roller 9 can be appropriately adjusted so that the gap between the active roller 9 and the driven roller 10 can match the height of the channel steel 4; based on h2, the distances between the first flange 2 and the second flange 3, the third flange 7 and the fourth flange 8 can be adjusted respectively, so as to effectively clamp and position the two short arm ends of the channel steel 4; based on h4, the distance between the second flange 3 and the fourth flange 8 can be adjusted so that the total width of the channel steel 4 can be matched. By installing a portable level 6 on the flange, it is used for horizontal correction when fixing with the flange positioning block 1, which avoids the problem that the first flange 2, the second flange 3, the third flange 7 and the fourth flange 8 are not in the same horizontal plane, so that the bent channel steel 4 will not be uneven at both ends.
