Description

Technical Field

[0001] This utility model relates to the field of ring rolling mills, specifically a servo centering device for axial synchronous ring rolling of large-diameter seamless aluminum tubes. Background Technology

[0002] A ring rolling mill is a forging and pressing equipment used in metal processing. It is mainly used to produce seamless ring parts. It uses radial and axial rolling forces to gradually roll heated metal billets into precision ring parts with larger diameters and thinner walls. The servo centering device for synchronous radial and axial rolling of large-diameter seamless aluminum tubes is mainly used to ensure accurate centering and dimensional control of aluminum tubes during synchronous radial and axial rolling.

[0003] In the existing technology, due to the different sizes of aluminum tubes for different purposes, existing ring rolling mills are not convenient for rolling metal rings of different thicknesses by changing the height of the drive roller, which reduces the applicability of the ring rolling mill. At the same time, since the ring rolling mill may generate vibration during the ring rolling process, causing the aluminum tube to shift axially, existing ring rolling mills are not convenient for limiting the aluminum tube to prevent axial shift, which reduces the ring rolling quality of the ring rolling mill. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of not being able to roll metal rings of different thicknesses by changing the height of the drive roller and not being able to limit the aluminum tube to prevent axial displacement, this utility model proposes a servo centering device for synchronous axial rolling of large-diameter seamless aluminum tubes.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the servo centering device for axial synchronous rolling of large-diameter seamless aluminum tubes described in this utility model includes a rolling mill body, a sliding groove is provided on one side of the rolling mill body, an adjustment component is slidably connected to the surface of the sliding groove, and a connecting rod is fixedly connected to the middle of one side of the rolling mill body, with a limit component connecting one end of the connecting rod.

[0006] The adjustment assembly includes a sliding plate slidably connected to the surface of the slide groove, a drive roller rotatably connected to one side of the sliding plate, a connecting plate fixedly connected to one side of the drive roller, a sliding plate fixedly connected to the top of the connecting plate, and an electric telescopic rod fixedly connected to the middle of the top of the sliding plate.

[0007] The limiting component includes a limiting plate that overlaps one end of the connecting rod, a connecting block that is fixedly connected to one edge of the limiting plate, and an electric push rod that is rotatably connected to the surface of the connecting block.

[0008] Preferably, a base plate is rotatably connected to the bottom of the limiting plate, and an electric push rod is rotatably connected to the top edge of the base plate.

[0009] Preferably, a telescopic plate is fixedly connected to one edge of the ring rolling mill body, and a limit roller is rotatably connected to one end of the telescopic plate.

[0010] Preferably, a top plate is fixedly connected to one side of the electric telescopic rod, and the ring rolling machine body is fixedly connected to the bottom edge of the top plate.

[0011] Preferably, a laser rangefinder is fixedly connected to the surface of the support rod, with one end of the laser rangefinder facing the surface of the limiting roller.

[0012] Preferably, a servo drive mechanism is fixedly connected to one side of the telescopic plate, and a laser rangefinder is connected to one end of the servo drive mechanism via a wire.

[0013] The advantages of this utility model are:

[0014] 1. By adjusting the structural settings of the components, when using the device, the aluminum tube is placed on the support rod and the aluminum tube is limited. Then, the electric telescopic rod is activated to extend the electric telescopic rod and push the sliding plate down until the drive roller presses against the top of the aluminum tube. This allows the device to change the height of the drive roller to roll metal rings of different thicknesses, thus improving the applicability of the ring rolling mill.

[0015] 2. Through the structural design of the limiting component, before using the device, the aluminum tube is placed on the support rod, and then the electric push rod is energized to extend it. Since both ends of the electric push rod are rotatably connected, when the electric push rod extends, it pushes the limiting plate to flip upward until it overlaps with the support rod. At this time, the annular baffle on the limiting plate can limit the axial displacement of the aluminum tube, thereby improving the ring rolling quality of the ring rolling machine.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, the servo centering device for axial synchronous rolling of large-diameter seamless aluminum tubes includes a rolling mill body 1. A groove is provided on one side of the rolling mill body 1, and an adjustment component 2 is slidably connected to the surface of the groove. A connecting rod 3 is fixedly connected to the middle of one side of the rolling mill body 1, and a limit component 4 is connected to one end of the connecting rod 3.

[0024] The adjustment assembly 2 includes a sliding plate 201 slidably connected to the surface of the slide groove, a drive roller 202 rotatably connected to one side of the sliding plate 201, a connecting plate 203 fixedly connected to one side of the drive roller 202, a sliding plate 201 fixedly connected to the top of the connecting plate 203, and an electric telescopic rod 204 fixedly connected to the middle of the top of the sliding plate 201.

[0025] The limiting component 4 includes a limiting plate 401 that overlaps one end of the connecting rod 3. A connecting block 402 is fixedly connected to one edge of the limiting plate 401. An electric push rod 403 is rotatably connected to the surface of the connecting block 402.

[0026] During operation, by adjusting the structural settings of component 2, the aluminum tube is placed on the support rod 3 and limited. Then, the electric telescopic rod 204 is activated to extend the rod, pushing the sliding plate 201 down until the drive roller 202 presses against the aluminum tube. This allows the device to change the height of the drive roller 202 to roll metal rings of different thicknesses, improving the applicability of the ring rolling mill. Through the structural settings of the limiting component 4, before using the device, the aluminum tube is placed on the support rod 3, and then the electric push rod 403 is energized to extend it. Since both ends of the electric push rod 403 are rotatably connected, when the electric push rod 403 extends, it pushes the limiting plate 401 to flip upward until it overlaps with the support rod 3. At this time, the annular baffle on the limiting plate 401 can limit the axial displacement of the aluminum tube, improving the ring rolling quality of the ring rolling mill.

[0027] Furthermore, the bottom of the limiting plate 401 is rotatably connected to the base plate 5, and the top edge of the base plate 5 is rotatably connected to the electric push rod 403.

[0028] During operation, the base plate 5 provides a rotation connection point for the limit plate 401 and the electric push rod 403.

[0029] Furthermore, a telescopic plate 6 is fixedly connected to one edge of the ring rolling mill body 1, and a limit roller 7 is rotatably connected to one end of the telescopic plate 6.

[0030] During operation, the telescopic plate 6 and the limiting roller 7 are set up so that the position of the limiting roller 7 can be controlled by the extension and retraction of the telescopic plate 6, thereby radially limiting the aluminum tube.

[0031] Furthermore, a top plate 8 is fixedly connected to one side of the electric telescopic rod 204, and a ring rolling machine body 1 is fixedly connected to the bottom edge of the top plate 8;

[0032] During operation, the electric telescopic rod 204 can be fixed in a vertical position by means of the top plate 8.

[0033] Furthermore, a laser rangefinder 9 is fixedly connected to the surface of the support rod 3, with one end of the laser rangefinder 9 facing the surface of the limiting roller 7;

[0034] During operation, the laser rangefinder 9 can monitor in real time the distance between the aluminum tube and the limit roller 7 and the support rod 3.

[0035] Furthermore, a servo drive mechanism 10 is fixedly connected to one side of the telescopic plate 6, and a laser rangefinder 9 is connected to one end of the servo drive mechanism 10 via a wire.

[0036] During operation, the servo drive mechanism 10 is set to push the telescopic plate 6 to extend and retract based on the distance calculated by the laser rangefinder 9 and the corresponding electrical signal transmitted through the wire. This controls the position of the two limit rollers 7 in real time, ensuring that the distances measured by the two laser rangefinders 9 are equal, thereby fixing the aluminum tube radially.

[0037] Working principle: When using this device, the aluminum tube is placed on the support rod 3, and then the electric push rod 403 is energized to extend it. Since both ends of the electric push rod 403 are rotatably connected, when the electric push rod 403 extends, it pushes the limiting plate 401 to flip upward until it overlaps with the support rod 3, thus limiting the axial direction. At the same time, the laser rangefinder 9 is energized. Based on the distance calculated by the laser rangefinder 9, the corresponding electrical signal is transmitted through the wire, causing the servo drive mechanism 10 to push the telescopic plate 6 to extend and retract, thereby controlling the position of the two limiting rollers 7 in real time, ensuring that the distances measured by the two laser rangefinders 9 are equal, and the aluminum tube is radially centered and limited. After the aluminum tube is limited, the electric telescopic rod 204 is activated to extend it, pushing the sliding plate 201 down until the drive roller 202 presses against the top of the aluminum tube. This allows the device to change the height of the drive roller 202 to roll metal rings of different thicknesses.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
