[0021] Reference below Figure 1 and Figure 2 The angle steel and channel steel rolling device according to the embodiment of the present invention is described.
[0022] like Figure 1 and Figure 2 As shown, the angle steel and channel steel rolling device according to the embodiment of the present invention includes a machine base 100, an intermediate jacket 200 and a limiting jacket 300.
[0023] The pressing rollers are located on the machine base 100, and the pressing rollers include 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, and the profile 500 includes a middle plate part 510 in the middle and vertical plate parts 520 on the left and right sides; the middle jacket 200 is sleeved on the first roller 130 and / or the second roller 140, and the outer peripheral wall of the middle jacket 200 has an middle pressing surface 211, and the middle pressing surface 211 can correspond to the middle plate part 510, and the side of the middle jacket 200 has a side clamping surface 213; the limiting jackets 300 are respectively arranged on the left and right sides of the middle jacket 200, and each side of the limiting jacket 300 has a limiting clamping surface 311, and the side clamping surfaces 213 and the limiting clamping surfaces 311 correspond to the two sides of the vertical plate part 520 respectively.
[0024] For example, Figure 1 and Figure 2 As shown, the pressing roller is located on the machine base 100, that is, the pressing roller is relatively fixed on the machine base 100 during operation. The pressing 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 specific bending method can refer to other similar rolling devices in the prior art. The profile 500 includes a middle plate part 510 in the middle and vertical plate parts 520 on the left and right sides. The specific shapes of the middle plate part 510 and the vertical plate part 520 are determined according to the design requirements of the profile 500 to be prepared, and are suitable for various angle steels, channel steels or other similar profiles.
[0025] Reference Figure 3 The intermediate jacket 200 is mounted on the first roller 130 and / or the second roller 140. The outer peripheral wall of the intermediate jacket 200 has an intermediate pressing surface 211, which can correspond to the intermediate plate portion 510, that is, the intermediate plate portion 510 of the profile 500 is pressed by the intermediate pressing surface 211 on the intermediate jacket 200. The side edge of the intermediate jacket 200 has a side clamping surface 213. Figure 4The limiting sleeves 300 are respectively arranged on the left and right sides of the middle sleeve 200, and each side of the limiting sleeve 300 has a limiting clamping surface 311. The side clamping surfaces 213 and the limiting clamping surfaces 311 respectively correspond to the two sides of the vertical plate part 520, that is, the side clamping surfaces 213 on the middle sleeve 200 cooperate with the limiting clamping surfaces 311 on the adjacent limiting sleeves 300 to clamp the two sides of the vertical plate part 520 of the profile 500.
[0026] In actual operation, the middle jacket 200 and the limiting jacket 300 are set on the first roller 130 as an example. Figure 5 When the profile 500 needs to be rolled, the profile 500 is inserted into the gap between the middle jacket 200, the limiting jacket 300 and the second roller 140, and the middle position of the profile 500 is aligned with the middle pressing surface 211, and the two sides of the profile 500 are aligned with the gap between the side clamping surface 213 and the limiting clamping surface 311. Then, as the first roller 130 and the second roller 140 rotate, the profile 500 can be bent to perform the rolling process.
[0027] During the rolling process, the middle pressing surface 211 on the middle jacket 200 cooperates with the second roller 140 to press the middle plate portion 510 of the profile 500, and the side clamping surface 213 on the left side of the middle jacket 200 cooperates with the limiting clamping surface 311 on the left limiting jacket 300 to clamp the vertical plate portion 520 on the left side of the profile 500, and the side clamping surface 213 on the right side of the middle jacket 200 cooperates with the limiting clamping surface 311 on the left limiting jacket 300 to clamp the vertical plate portion 520 on the left side of the profile 500. In this way, the rolling device of the present invention can match the profile 500 to perform the rolling work.
[0028] Since the intermediate jacket 200 and the limiting jacket 300 are both mounted on the first roller 130, the intermediate jacket 200 and the limiting jacket 300 can be flexibly assembled and disassembled on the first roller 130, and the installation positions of the intermediate jacket 200 and the limiting jacket 300 on the first roller 130 can be adjusted easily. Therefore, the intermediate jacket 200 and the limiting jacket 300 can be flexibly adjusted or even replaced according to the specific shape of the profile 500. In other words, referring to Figure 6 The rolling device of the present invention can adapt to profiles 500 of different shapes, and can match profiles 500 of various shapes and sizes without replacing the first roller 130 and the second roller 140.
[0029] In some specific embodiments of the present invention, referring to Figure 6 The middle jacket 200 and the limiting jacket 300 are sleeved on the second roller 140 , that is, the middle jacket 200 and the limiting jacket 300 on the first roller 130 and the second roller 140 cooperate to press the profile 500 to perform the rolling work.
[0030] In some specific embodiments of the present invention, the intermediate jacket 200 and the limiting jacket 300 are mounted on the first roller 130 and the second roller 140, that is, the intermediate jacket 200 and the limiting jacket 300 on the first roller 130 cooperate with the intermediate jacket 200 and the limiting jacket 300 on the second roller 140 to press the profile 500 to roll. This method is suitable for the profile 500 with the vertical plate portion 520 extending from the upper and lower sides.
[0031] In some specific embodiments of the present invention, an intermediate jacket 200 and a limiting jacket 300 are mounted on the first roller 130, and the limiting jacket 300 is located on the left or right side of the intermediate jacket 200, that is, the intermediate jacket 200 and the limiting jacket 300 on the first roller 130 cooperate with the second roller 140 to press the profile 500 to roll. This method is suitable for profiles 500 with only a single-side vertical plate portion 520. Similarly, an intermediate jacket 200 and a limiting jacket 300 in this method can also be installed on the second roller 140.
[0032] In some specific embodiments of the present invention, the shape of the middle pressure surface 211 on the middle jacket 200 is designed according to the shape of the middle plate portion 510 of the profile 500 .
[0033] In some specific embodiments of the present invention, the shapes of the side clamping surface 213 on the middle jacket 200 and the limiting clamping surface 311 on the limiting jacket 300 are designed according to the shapes of the two sides of the vertical plate portion 520 clamping the profile 500 .
[0034] In some embodiments of the present invention, there is one first roller 130 and one or two second rollers 140 .
[0035] In some specific embodiments of the present invention, when the first roller 130 and the second roller 140 are both one, the first roller 130 and the second roller 140 are arranged at upper and lower sides in a vertical direction or an inclined direction.
[0036] In some specific embodiments of the present invention, 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 triangle shape.
[0037] In some embodiments of the present invention, reference Figure 1 The base 100 is provided with a lifting chute 110, a lifting slide 120 is provided on the lifting chute 110, and the first roller 130 is connected to the lifting slide 120. In this way, the height position of the lifting slide 120 can be adjusted by lifting and lowering the lifting slide 120 in the lifting chute 110, and the height of the first roller 130 can be adjusted. When the profile 500 needs to be rolled, the profile 500 passes through the position 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.
[0038] In a further embodiment of the present invention, the lifting slide 110 is connected to the lifting slide 120 via a lifting adjustment screw 121 , so that the lifting and lowering of the lifting slide 120 can be controlled by rotating the lifting adjustment screw 121 .
[0039] In some embodiments of the present invention, reference Figure 3 , Figure 4 The intermediate jacket 200 is composed of a plurality of intermediate jacket components 210 spliced together, and the limiting jacket 300 is composed of a plurality of limiting jacket components 310 spliced together. The intermediate jacket components 210 and the limiting jacket components 310 are both in the shape of a "C". The ends of the intermediate jacket components 210 are connected together by a connecting piece 400 to form a ring-shaped intermediate jacket 200. The ends of the limiting jacket components 310 are connected together by a connecting piece 400 to form a ring-shaped limiting jacket 300. That is, if the intermediate jacket 200 and the limiting jacket 300 need to be disassembled from the first roller 130 / the second roller 140, it is only necessary to separate the intermediate jacket components 210 and the limiting jacket components 310. On the contrary, if the intermediate jacket 200 and the limiting jacket 300 need to be installed on the first roller 130 / the second roller 140, the ends of the intermediate jacket components 210 and the ends of the limiting jacket components 310 can be connected into a ring shape through the connecting piece 400 to clamp the first roller 130 / the second roller 140. The "C"-shaped structure of the intermediate jacket component 210 and the limiting jacket component 310 can match the outer peripheral wall surface of the first roller 130 / the second roller 140.
[0040] In a further embodiment of the present invention, the ends of the intermediate jacket member 210 are provided with an intermediate jacket docking plate 214 and an intermediate jacket concave portion 216, and the intermediate jacket docking plate 214 is provided with an intermediate jacket docking hole 215. After the adjacent intermediate jacket docking plates 214 are docked, the connecting piece 400 passes through the intermediate jacket concave portion 216 and the intermediate jacket docking hole 215 to connect the intermediate jacket members 210 together, ensuring that the connection between the intermediate jacket members 210 is sufficiently stable and reliable. The design of the intermediate jacket concave portion 216 ensures that the connecting piece 400 has enough space to pass through the intermediate jacket docking hole 215, and does not affect the operation of the intermediate pressure surface 211, nor does it affect the solid structure of the intermediate jacket 200 to ensure that the structural strength is sufficiently high.
[0041] In a further embodiment of the present invention, a limiting jacket docking plate 313 is provided at the end of the limiting jacket component 310, and a limiting jacket docking hole 314 is provided on the limiting jacket docking plate 313. The connecting piece 400 passes through the limiting jacket docking hole 314 to connect the limiting jacket components 310 together, ensuring that the connection between the limiting jacket components 310 is sufficiently stable and reliable.
[0042] In some embodiments of the present invention, the connecting member 400 is a bolt, which makes the connection between the intermediate jacket components 210 and the limiting jacket components 310 more convenient and easy.
[0043] In some specific embodiments of the present invention, the connector 400 may be a double-threaded screw and a nut. The double-threaded screw passes through the middle jacket concave portion 216 and the middle jacket docking hole 215, and the nut is installed at both ends of the double-threaded screw so that the nut clamps the middle jacket docking plate 214, so that the middle jacket components 210 are connected together. The double-threaded screw passes through the limiting jacket docking hole 314, and the nut is installed at both ends of the double-threaded screw so that the nut clamps the limiting jacket docking plate 313, so that the limiting jacket components 310 are connected together.
[0044] In some specific embodiments of the present invention, the connecting member 400 may be a screw and a nut. The screw passes through the middle jacket concave portion 216 and the middle jacket docking hole 215, and the nut is installed on the screw, so that the screw head and the nut clamp the middle jacket docking plate 214, so that the middle jacket component 210 is connected together. The screw passes through the limiting jacket docking hole 314, and the nut is installed on the screw, so that the screw head and the nut clamp the limiting jacket docking plate 313, so that the limiting jacket component 310 is connected together.
[0045] In some embodiments of the present invention, reference Figure 1 , Figure 2 The inner wall of the middle jacket 200 is provided with a middle jacket fixing surface 212, and the middle jacket fixing surface 212 presses against the outer wall of the first roller 130 and / or the second roller 140 to ensure that the middle jacket 200 is installed on the first roller 130 / the second roller 140 sufficiently firmly and reliably.
[0046] In some embodiments of the present invention, each limiting jacket 300 has a limiting jacket fixing surface 312 on its inner circumferential wall, and the limiting jacket fixing surface 312 presses on the outer circumferential wall of the first roller 130 and / or the second roller 140 to ensure that the limiting jacket 300 is installed on the first roller 130 / the second roller 140 sufficiently firmly and reliably.
[0047] In some embodiments of the present invention, reference Figure 4 The limiting jacket 300 is provided with reinforcing ribs 315 for improving the structural strength of the limiting jacket 300 .
[0048] In a further embodiment of the present invention, each limiting jacket 300 has a limiting jacket fixing surface 312 on its inner circumferential wall, and the limiting jacket fixing surface 312 presses on the outer circumferential wall of the first roller 130 and / or the second roller 140, and a recess is formed between the limiting jacket fixing surface 312 and the limiting clamping surface 311 as a limiting jacket groove 316, and the reinforcing rib 315 is located on the limiting jacket groove 316, which not only makes the limiting jacket 300 more compact in structure, but also the reinforcing rib 315 does not need to extend out of the limiting jacket 300, and at the same time, it exerts supporting force on the limiting jacket fixing surface 312 and the limiting clamping surface 311 and plays a supporting role.
[0049] In a further embodiment of the present invention, the reinforcing rib 315 is a plate-like structure, the reinforcing rib 315 is perpendicular to the cross-section at the connection position of the limiting sleeve fixing surface 312 corresponding to the reinforcing rib 315, and the reinforcing rib 315 is perpendicular to the limiting clamp surface 311, ensuring that the reinforcing rib 315 can generate sufficiently large supporting force on the limiting sleeve fixing surface 312 and the limiting clamp surface 311.
[0050] A reinforcing rib 315 is arranged on the outside of the limiting jacket 300, and the reinforcing rib 315 is connected to the limiting jacket fixing surface 312 and the limiting clamping surface 311 to ensure that the structural strength of the limiting jacket 300 is high enough, especially to ensure that the limiting jacket fixing surface 312 on the limiting jacket 300 has sufficient strength to cooperate with the side clamping surface 213 on the middle jacket 200 to clamp the profile.
