[0026] The following will refer to Figure 1-Figure 5 A swing arm device 100 for an ironing roll of a cold rolling mill according to a preferred embodiment of the present invention is described in detail.
[0027] The ironing roller 130 of the cold rolling mill is a key device to ensure the tightness and flatness of the aluminum strip when it is rolled at the exit of the rolling mill. The two ends of the ironing roller 130 have connecting shafts (not shown), and the ironing roller 130 is connected to the swing arm device 100 via the connecting shaft. The swing arm device 100 can be driven to rotate by a cylinder, and then can drive the ironing roller 130 to swing up and down, so that the ironing roller 130 presses on or leaves the surface of the strip coil. The swing arm device 100 includes a first swing arm and a second swing arm respectively connected to the two ends of the ironing roller 130, and the first swing arm and the second swing arm have substantially the same structure.
[0028] like Figure 1 and Figure 2 As shown, the swing arm device 100 has a connection structure 110 at its rear end, and the swing arm device 100 is connected to the connection shaft via the connection structure 110. It should be noted that the directional terms such as "upper", "lower", "front", and "rear" mentioned herein are relative to the cold rolling mill ironing roller 130 in a normal installation state, wherein the coiler 140 located at the exit of the cold rolling mill and the ironing roller 130 located below the coiler 140 are located at the "rear" part of the cold rolling mill.
[0029] The following will refer to Figure 1-Figure 5 The connection structure 110 of the swing arm device 100 according to the preferred embodiment of the present utility model is described in detail.
[0030] like Figure 1 and Figure 2 As shown, the connection structure 110 is located at the rear end of the swing arm device 100, and the connection structure 110 includes a connection body 111, and the connection body 111 has an opening 112 facing upward. In the actual assembly process, the connection shaft of the ironing roller 130 can be assembled to the connection body 111 through the opening 112.
[0031] like Figure 3 and Figure 4 As shown, the connection structure 110 also includes a connection ear 113, the outer contour of the connection ear 113 is roughly similar to the outer contour of the opening 112, and both are roughly square. The connection ear 113 is arranged in the opening 112. A circular through hole 114 is arranged in the middle of the connection ear 113, and the connection shaft can extend through the through hole 114.
[0032] Preferably, U-shaped slots 113a are formed around the connecting ears 113, and the connecting ears 113 can be snapped at the periphery of the opening 112 through the U-shaped slots 113a. In the snapped state, the edge of the connecting body 111 is snapped in the U-shaped slots 113a.
[0033] Preferably, if Figure 5As shown, the connection structure 110 also includes an upper pressing plate 115, which is connected to the connection body 111 above the opening 112. Exemplarily, the upper pressing plate 115 can be fastened to the connection body 111 by a threaded fastener. Further preferably, the upper pressing plate 115 includes an upper pressing plate body 115a and a protrusion 115b extending downward from the upper pressing plate body 115a, the transverse dimension of the protrusion 115b matches the transverse dimension of the opening 112, and the protrusion 115b extends into the opening 112. By arranging the protrusion 115b assembled into the opening 112 below the upper pressing plate 115, the two ends of the protrusion 115b can be abutted against the opening 112, so that the upper pressing plate 115 can be further prevented from falling off under the action of the backward force, thereby ensuring the stability of the structure. When the upper pressing plate 115 is installed, the upper slots 113 a of the connecting ears 113 are engaged with the upper pressing plate 115 .
[0034] According to the swing arm device 100 of the above solution, the orientation of the opening 112 is changed to face upward, and the force direction of the contact point between the aluminum strip material and the ironing roller 130 is still backward, so the orientation of the opening 112 is different from the force direction of the contact point between the material and the ironing roller 130, and the upper pressing plate 115 does not need to be arranged in the force direction, so that it can be prevented from falling off. This solution can improve the stability of the overall structure of the swing arm device 100 and prevent the connecting shaft of the ironing roller 130 from falling off from the opening 112.
[0035] Preferably, the connecting structure 110 also includes a displacement adjusting member connected to the connecting body 111, and the displacement adjusting member can adjust the displacement of the swing arm device and the connecting shaft connected to the swing arm device, so as to adjust the coaxiality of the first swing arm and the second swing arm on both sides of the ironing roller 130, and can adjust the parallelism of the ironing roller 130 and the winding shaft of the winder 140.
[0036] Preferably, the displacement adjusting member comprises a first adjusting bolt and a second adjusting bolt (not shown), such as Figure 1 As shown, a first through hole 116 and a second through hole 117 are also provided on the connecting body 111.

The first adjusting bolt and the second adjusting bolt can respectively pass through the first through hole 116 and the second through hole 117 and extend into the opening portion 112.
[0037] Continue to refer Figure 1 A groove 118 is further provided below the connecting body 111, the groove 118 opens downward, and the second through hole 117 extends through the groove 118. The provision of the groove 118 can reduce the weight of the swing arm device 100 and make the product structure lightweight.
[0038] In order to reduce the vibration of the swing arm device 100 during use, the connection structure 110 further includes a shock absorbing component, which is arranged in the opening portion 112. Preferably, the shock absorbing component includes a first shock absorbing block 119 and a second shock absorbing block 120, which can be respectively constructed as a brass plate with a thickness of about 10 mm, and the first shock absorbing block 119 and the second shock absorbing block 120 are respectively arranged at the rear and the bottom of the opening portion 112. In the state where the card slot 113a is carded to the connection body 111, the first shock absorbing block 119 and the second shock absorbing block 120 are respectively located in the card slot 113a, and the ends of the first adjusting bolt and the second adjusting bolt can abut against the first shock absorbing block 119 and the second shock absorbing block 120 respectively.
[0039] In order to enhance the overall stability of the swing arm device 100, preferably, as Figure 1 As shown, the swing arm device 100 further includes a first connecting rod 121 disposed near the connecting structure 110, the first connecting rod 121 is connected between the first swing arm and the second swing arm, and the first connecting rod 121 is preferably a channel steel structure. Further preferably, the first connecting rod 121 is connected to the first swing arm and the second swing arm through a threaded fastener 122, which not only ensures the strength of the overall swing arm device 100, but also reduces the weight of the swing arm device 100, and can also facilitate the disassembly and installation of the first connecting rod 121.
[0040] Preferably, the swing arm device 100 further includes a second connecting rod 123, which is connected between the first swing arm and the second swing arm. The second connecting rod 123 is preferably a channel steel structure. Figure 1 As shown, the second connecting rod 123 is connected to the connecting body 111 below the connecting body 111. Preferably, the second connecting rod 123 is connected to the connecting body 111 through a threaded fastener, and a third through hole 124 communicating with the groove 118 and the second through hole 117 is provided on the second connecting rod 123.
[0041] The above-mentioned solution of the present application can solve the problem of frequent loosening or even breaking of the bolts of the swing arm device 100 of the ironing roller in the prior art, thereby improving the reliability of the ironing roller 130.
