[0018] Through the personnel in this field, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0019] When a traditional ring rolling machine is in use, it does not have a structure to prevent the flange from warping upwards. This causes the flange to warp upwards due to the lateral force during processing, resulting in a decline in the production quality of the flange, thus bringing inconvenience to the use of the staff.

[0020] In view of this, the present utility model provides a pressure roller device for preventing the flange of a ring rolling machine from warping upwards. Through the cooperation of a support, a bottom plate, a bracket, an adjustment device, and a limiting device, a pressure roller device can be installed on the guide wheel arm of the ring rolling machine, so that when the ring rolling machine rolls the flange, the flange will not warp upwards due to the lateral force, thereby ensuring that the flange rolling process is effectively controllable, and the flange size and concentricity can be rolled more in line with the set size.

[0021] Embodiment 1: As can be seen from Figure 1 、 2 、3 and 4, a pressure roller device for preventing the flange of a ring rolling machine from warping upwards includes a bottom plate 6. One side of the top of the bottom plate 6 is provided with a support 1. The end of the support 1 is rotatably connected to a bracket 5. The pressure roller device for preventing the flange of a ring rolling machine from warping upwards further includes: a limiting device 2 installed at the end of the bracket 5; a protection device 4 arranged above one side of the bracket 5; an adjustment device 3 installed on the top of the bottom plate 6. Among them, the limiting device 2 can limit the flange during the production of the flange, the protection device 4 can prevent the limiting device 2 from damaging the flange, and the adjustment device 3 can change the positions of the protection device 4 and the limiting device 2.

[0022] In the specific implementation process, it is particularly pointed out that the adjustment device 3 can adjust the position of the limiting device 2, and then the limiting device 2 can be used to limit the flange to ensure the stability during the flange processing. The protection device 4 can prevent the phenomenon that the flange is deformed and damaged due to the excessive instantaneous impact pressure of the limiting device 2 on the flange.

[0023] Furthermore, openings are processed at the four corners of the bottom plate 6.

[0024] In the specific implementation process, it is particularly worth noting that the staff can use Luo Shuang through the opening to install the pressure roller device for preventing the flange from warping on the ring rolling machine onto the guide wheel arm of the ring rolling machine;

[0025] Specifically, when using the pressure roller device for preventing the flange from warping on the ring rolling machine, first, the staff installs the pressure roller device for preventing the flange from warping on the ring rolling machine onto the guide wheel arm of the ring rolling machine, and then it can be put into use. The staff controls the adjusting device 3, and the adjusting device 3 can drive the bracket 5 to rotate along the end of the support 1, thereby changing the position of the limiting device 2. When the limiting device 2 reaches the appropriate position, the flange can be limited. When limiting the flange, the protection device 4 can prevent the flange from being damaged and deformed due to a large instantaneous impact.

[0026] Embodiment Two: From Figure 1 、 2 and 4, it can be seen that the adjusting device 3 includes: an electric push rod 301, the model of the electric push rod 301 is not specifically limited, as long as it meets the use requirements, and it is detachably connected to one side of the top of the bottom plate 6; a slider 303, rotatably connected to the output end of the electric push rod 301; a slide rail 302, slidably clamped to the inner wall of the slider 303 and fixedly connected to the outer wall of the bracket 5; wherein, the electric push rod 301 can drive the slider 303 to move along the slide rail 302, thereby driving the bracket 5 to rotate along the end of the support 1;

[0027] In the specific implementation process, it is particularly worth noting that heat insulation measures should be taken for the electric push rod 301, and its specific method is not limited, as long as it meets the use requirements. The electric push rod 301 can drive the slider 303 to slide along the outer wall of the slide rail 302, thereby driving the bracket 5 to rotate along the end of the support 1;

[0028] Specifically, on the basis of the above Embodiment One, when it is necessary to change the position of the limiting device 2, the staff turns on the external power supply of the electric push rod 301. At this time, the electric push rod 301 can drive the slider 303 to slide along the outer wall of the slide rail 302, thereby driving the bracket 5 to rotate along the end of the support 1 to adjust the position of the limiting device 2.

[0029] Embodiment Three: From Figure 1 、 2 and 3, it can be seen that the limiting device 2 includes: a support plate 201, installed at the end of the bracket 5; two threaded rods 202, both threadedly connected to the inner wall of the support plate 201; a curved plate 203, arranged below the two threaded rods 202; a roller 204, rotatably connected to the inner wall of the curved plate 203; wherein, the roller 204 can rotate along the inner wall of the curved plate 203, and the staff can install the curved plate 203 and the roller 204 onto the support plate 201 through the threaded rods 202;

[0030] In the specific implementation process, it is worth noting that nuts are installed at both ends of the threaded rod 202 so as to strengthen the connection strength between the threaded rod 202 and the support plate 201 through the nuts;

[0031] Specifically, on the basis of the above-mentioned Embodiment 1 and Embodiment 2, the staff can use the threaded rod 202 to install the curved plate 203 and the roller 204 on the support plate 201. When limiting the flange, the roller 204 can rotate along the inner wall of the curved plate 203.

[0032] Embodiment 4: From Figure 1 、 2 and 3, it can be seen that the protection device 4 includes: two sleeves 401, which are respectively movably connected to the outer walls of the two threaded rods 202 and are fixedly connected to the outer wall of the curved plate 203; two springs 403, which are respectively installed in the inner walls of the two sleeves 401; two blocks 402, which are respectively installed at the ends of the two springs 403 and are respectively fixedly connected to the bottoms of the two threaded rods 202; wherein, the sleeve 401 can move along the outer wall of the threaded rod 202, thereby compressing the spring 403;

[0033] In the specific implementation process, it is worth noting that when the roller 204 limits the flange, the curved plate 203 will drive the sleeve 401 to move along the outer walls of the block 402 and the threaded rod 202, thereby changing the shape of the spring 403. Therefore, the elastic force of the spring 403 can be used for buffer protection;

[0034] Specifically, on the basis of the above-mentioned Embodiment 1, Embodiment 2 and Embodiment 3, when the roller 204 contacts the outer wall of the flange, the roller 204 will drive the curved plate 203 to move, and then the curved plate 203 will drive the sleeve 401 to move along the outer walls of the threaded rod 202 and the block 402. At this time, the elastic potential energy of the spring 403 can be used for buffer protection.
