[0032] The following is for reference. Figure 1 and Figure 2 This invention describes a device for rolling angle steel and channel steel according to an embodiment of the present invention.
[0033] like Figure 1 and Figure 2 As shown, the angle steel and channel steel rolling device according to an embodiment of the present utility model includes a base 100, an intermediate jacket 200 and a limiting jacket 300.
[0034] The pressure roller is located on the machine base 100. The pressure roller includes a first roller 130 on the upper side and a second roller 140 on the lower side. The first roller 130 and the second roller 140 can cooperate to bend the profile 500. The profile 500 includes a middle plate portion 510 in the middle and vertical plate portions 520 on the left and right sides. The middle sleeve 200 is fitted on the first roller 130 and / or the second roller 140. The outer peripheral wall of the middle sleeve 200 has a middle pressing surface 211, which can correspond to the middle plate portion 510. The side of the middle sleeve 200 has a side clamping surface 213. The limiting sleeves 300 are respectively provided on the left and right sides of the middle sleeve 200. The side of each limiting sleeve 300 has a limiting clamping surface 311. The side clamping surface 213 and the limiting clamping surface 311 correspond to the two sides of the vertical plate portion 520, respectively.
[0035] For example, such as Figure 1 and Figure 2As shown, the pressure roller is located on the machine base 100, meaning it remains relatively fixed during operation. The pressure roller includes an upper first roller 130 and a lower second roller 140. The first roller 130 and the second roller 140 cooperate to bend the profile 500. The specific bending method can be referenced from other similar rolling devices in the prior art. The profile 500 includes a central intermediate plate portion 510 and vertical plate portions 520 on both sides. The specific shapes of the intermediate plate portion 510 and the vertical plate portions 520 are determined according to the design requirements of the profile 500 to be manufactured, and are suitable for various angle steels, channel steels, or other similar profiles.
[0036] Reference Figure 3 An intermediate sleeve 200 is fitted onto the first roller 130 and / or the second roller 140. The outer peripheral wall of the intermediate sleeve 200 has an intermediate pressing surface 211, which corresponds to the intermediate plate portion 510, i.e., the intermediate plate portion 510 of the profile 500 is pressed down by the intermediate pressing surface 211 on the intermediate sleeve 200. The side of the intermediate sleeve 200 has a side clamping surface 213. (Refer to...) Figure 4 The limiting sleeves 300 are respectively provided on the left and right sides of the intermediate sleeve 200. Each limiting sleeve 300 has a limiting clamping surface 311 on its side. The side clamping surface 213 and the limiting clamping surface 311 correspond to the two sides of the vertical plate portion 520, that is, the two sides of the vertical plate portion 520 of the profile 500 are clamped by the side clamping surface 213 on the intermediate sleeve 200 and the limiting clamping surface 311 on the adjacent limiting sleeve 300.
[0037] In actual operation, taking the configuration of the intermediate jacket 200 and the limiting jacket 300 fitted onto the first roller 130 as an example, refer to... Figure 5 When profile 500 needs to be rolled, it is inserted into the gap between the intermediate clamp 200, the limiting clamp 300, and the second roller 140, with the middle position of profile 500 aligned with the middle pressing surface 211, and the two sides of profile 500 aligned with the gaps between the side clamping surfaces 213 and the limiting clamping surfaces 311. Then, as the first roller 130 and the second roller 140 rotate, profile 500 can be bent to perform the rolling process.
[0038] During the rolling process, the intermediate pressing surface 211 on the intermediate clamp 200, in conjunction with the second roller 140, presses down on the intermediate plate portion 510 of the profile 500. Furthermore, the side clamping surface 213 on the left side of the intermediate clamp 200, in conjunction with the limiting clamping surface 311 on the left limiting clamp 300, clamps the vertical plate portion 520 on the left side of the profile 500. Similarly, the side clamping surface 213 on the right side of the intermediate clamp 200, in conjunction with the limiting clamping surface 311 on the left limiting clamp 300, clamps the vertical plate portion 520 on the left side of the profile 500. In this way, the rolling device of this invention can be matched with the profile 500 to perform the rolling operation.
[0039] Since both the intermediate sleeve 200 and the limiting sleeve 300 are fitted onto the first roller 130, they can be flexibly installed and removed from the first roller 130, facilitating adjustments to their positions. Therefore, the intermediate sleeve 200 and the limiting sleeve 300 can be flexibly adjusted or even replaced according to the specific shape of the profile 500. In other words, referring to… Figure 6-1 , Figure 6-2 , Figure 6-3 , Figure 6-4 The rolling device of this utility model can adapt to profiles 500 of different shapes and sizes without changing the first roller 130 and the second roller 140.
[0040] In some specific embodiments of this utility model, reference is made to Figure 6-1 The intermediate sleeve 200 and the limiting sleeve 300 are fitted onto the second roller 140. That is, the intermediate sleeve 200 and the limiting sleeve 300 on the first roller 130 and the second roller 140 work together to press the profile 500 to perform the rolling operation.
[0041] In some specific embodiments of this utility model, reference is made to Figure 6-2 The intermediate sleeve 200 and the limiting sleeve 300 are fitted onto the first roller 130 and the second roller 140. That is, the intermediate sleeve 200 and the limiting sleeve 300 on the first roller 130 cooperate with the intermediate sleeve 200 and the limiting sleeve 300 on the second roller 140 to press the profile 500 for rolling. This method is suitable for profiles 500 with vertical plate sections 520 extending to the upper and lower sides.
[0042] In some specific embodiments of this utility model, reference is made to Figure 6-3 An intermediate sleeve 200 and a limiting sleeve 300 are fitted onto the first roller 130. The limiting sleeve 300 is located to the left or right of the intermediate sleeve 200. That is, the intermediate sleeve 200 and the limiting sleeve 300 on the first roller 130 cooperate with the second roller 140 to press the profile 500 for rolling. This method is suitable for profiles 500 with only a single-sided vertical plate portion 520. Similarly, the intermediate sleeve 200 and the limiting sleeve 300 can also be installed on the second roller 140.
[0043] In some specific embodiments of this utility model, reference is made to Figure 6-4 The shape of the intermediate pressing surface 211 on the intermediate jacket 200 is designed according to the shape of the intermediate plate portion 510 of the profile 500.
[0044] In some specific embodiments of this utility model, the shapes of the side clamping surface 213 on the intermediate clamping sleeve 200 and the limiting clamping surface 311 on the limiting clamping sleeve 300 are determined according to the shape design of both sides of the vertical plate portion 520 that clamps the profile 500.
[0045] In some embodiments of this utility model, there is one first roller 130 and one or two second rollers 140.
[0046] In some specific embodiments of this utility model, when there is only one first roller 130 and one second roller 140, the first roller 130 and the second roller 140 are arranged on the upper and lower sides in the vertical or inclined direction.
[0047] In some specific embodiments of this utility model, when there is one first roller 130 and two second rollers 140, the first roller 130 and the second roller 140 are arranged in a triangular shape.
[0048] In some embodiments of this utility model, reference is made to Figure 1 The machine base 100 is provided with a lifting slide 110, and a lifting slide block 120 is provided on the lifting slide 110. The first roller 130 is connected to the lifting slide block 120. In this way, the height position of the first roller 130 can be adjusted by raising and lowering the lifting slide block 120 in the lifting slide 110. When it is necessary to roll the profile 500, the profile 500 is passed between the first roller 130 and the second roller 140, and then the first roller 130 descends to press the profile 500, so that the profile 500 can be rolled.
[0049] In a further embodiment of this utility model, the lifting slide 110 and the lifting slide 120 are connected by a lifting adjustment screw 121, so that the lifting slide 120 can be raised and lowered by rotating the lifting adjustment screw 121.
[0050] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4The intermediate sleeve 200 is composed of several intermediate sleeve components 210 joined together, and the limiting sleeve 300 is composed of several limiting sleeve components 310 joined together. Both the intermediate sleeve components 210 and the limiting sleeve components 310 are "C"-shaped. The ends of each intermediate sleeve component 210 are connected together by a connector 400 to form a ring-shaped intermediate sleeve 200. The ends of each limiting sleeve component 310 are connected together by a connector 400 to form a ring-shaped limiting sleeve 300. Therefore, to remove the intermediate sleeve 200 and the limiting sleeve 300 from the first roller 130 / second roller 140, it is only necessary to separate the intermediate sleeve components 210 and the limiting sleeve components 310. Conversely, if intermediate sleeves 200 and limiting sleeves 300 need to be installed on the first roller 130 / second roller 140, then the ends of each intermediate sleeve component 210 and the ends of each limiting sleeve component 310 are connected in a ring shape by connectors 400 to clamp the first roller 130 / second roller 140. The "C"-shaped structure of the intermediate sleeve component 210 and the limiting sleeve component 310 can match the outer peripheral wall surface of the first roller 130 / second roller 140.
[0051] In a further embodiment of this utility model, the end of the intermediate jacket component 210 is provided with an intermediate jacket mating plate 214 and an intermediate jacket concave portion 216. The intermediate jacket mating plate 214 is provided with an intermediate jacket mating hole 215. After adjacent intermediate jacket mating plates 214 are mated, the connector 400 passes through the intermediate jacket concave portion 216 and the intermediate jacket mating hole 215 to connect the intermediate jacket components 210 together, ensuring that the connection between the intermediate jacket components 210 is sufficiently stable and reliable. The design of the intermediate jacket concave portion 216 ensures that the connector 400 has enough space to pass through the intermediate jacket mating hole 215, while not affecting the operation of the intermediate pressure surface 211, nor affecting the fact that the intermediate jacket 200 can adopt a solid structure to ensure sufficient structural strength.
[0052] In a further embodiment of the present invention, a limiting sleeve mating plate 313 is provided at the end of the limiting sleeve component 310, and a limiting sleeve mating hole 314 is provided on the limiting sleeve mating plate 313. The connector 400 passes through the limiting sleeve mating hole 314 to connect the limiting sleeve components 310 together, ensuring that the connection between the limiting sleeve components 310 is sufficiently stable and reliable.
[0053] In some embodiments of this utility model, the connecting member 400 is a bolt, which makes it easier and more convenient to connect the intermediate clamping members 210 and the limiting clamping members 310.
[0054] In some specific embodiments of this utility model, the connector 400 can be a double-ended threaded screw and a nut. The double-ended threaded screw passes through the concave portion 216 of the intermediate sleeve and the mating hole 215 of the intermediate sleeve. The nut is installed at both ends of the double-ended threaded screw to clamp the mating plate 214 of the intermediate sleeve, thus connecting the intermediate sleeve components 210 together. The double-ended threaded screw passes through the mating hole 314 of the limiting sleeve. The nut is installed at both ends of the double-ended threaded screw to clamp the mating plate 313 of the limiting sleeve, thus connecting the limiting sleeve components 310 together.
[0055] In some specific embodiments of this utility model, the connector 400 can be a screw and a nut. The screw passes through the concave portion 216 of the intermediate sleeve and the mating hole 215 of the intermediate sleeve, and the nut is installed on the screw, so that the screw head and the nut clamp the mating plate 214 of the intermediate sleeve, connecting the intermediate sleeve components 210 together. The screw passes through the mating hole 314 of the limiting sleeve, and the nut is installed on the screw, so that the screw head and the nut clamp the mating plate 313 of the limiting sleeve, connecting the limiting sleeve components 310 together.
[0056] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 The intermediate jacket 200 has an intermediate jacket fixing surface 212 on its inner peripheral wall. The intermediate jacket fixing surface 212 presses against the outer peripheral wall of the first roller 130 and / or the second roller 140 to ensure that the intermediate jacket 200 is installed securely and reliably on the first roller 130 / second roller 140.
[0057] In some embodiments of this utility model, each limiting sleeve 300 has a limiting sleeve fixing surface 312 on its inner peripheral wall. The limiting sleeve fixing surface 312 presses against the outer peripheral wall of the first roller 130 and / or the second roller 140 to ensure that the limiting sleeve 300 is installed securely and reliably on the first roller 130 / second roller 140.
[0058] In some embodiments of this utility model, reference is made to Figure 4 The limiting sleeve 300 is provided with reinforcing ribs 315 to improve the structural strength of the limiting sleeve 300.
[0059] In a further embodiment of this utility model, each limiting sleeve 300 has a limiting sleeve fixing surface 312 on its inner peripheral wall. The limiting sleeve fixing surface 312 presses against the outer peripheral wall of the first roller 130 and / or the second roller 140. A recess is formed between the limiting sleeve fixing surface 312 and the limiting clamping surface 311 as a limiting sleeve groove 316. The reinforcing rib 315 is located on the limiting sleeve groove 316, which not only makes the structure of the limiting sleeve 300 more compact, but also eliminates the need for the reinforcing rib 315 to extend out of the limiting sleeve 300. At the same time, it applies a supporting force to the limiting sleeve fixing surface 312 and the limiting clamping surface 311 and plays a supporting role.
[0060] In a further embodiment of this utility model, the reinforcing rib 315 is a plate-shaped structure. The reinforcing rib 315 is perpendicular to the cross-section of the fixing surface 312 of the limiting sleeve corresponding to the connection position of the reinforcing rib 315, and the reinforcing rib 315 is perpendicular to the limiting clamping surface 311, so as to ensure that the reinforcing rib 315 can generate a sufficiently large supporting force on the fixing surface 312 and the limiting clamping surface 311 of the limiting sleeve.
[0061] The limiting sleeve 300 is provided with a reinforcing rib 315 on the outside. The reinforcing rib 315 is connected to the limiting sleeve fixing surface 312 and the limiting clamping surface 311 to ensure that the structural strength of the limiting sleeve 300 is high enough. In particular, it ensures that the limiting sleeve fixing surface 312 on the limiting sleeve 300 has sufficient strength to cooperate with the side clamping surface 213 on the intermediate sleeve 200 to clamp the profile.
[0062] According to the embodiments of the present invention, the rolling device can adapt to the rolling of angle steel, channel steel and other profiles of different shapes (such as I-beams) by adopting the above-mentioned angle steel and channel steel rolling device. Moreover, it can improve the working efficiency of the rolling device, reduce costs and help improve production efficiency.
