Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, specifically to a spinning equipment for arc-shaped ring parts. Background Technology

[0002] A spinning machine is a machine tool used for the plastic forming of metals. It rotates the workpiece and applies external force (such as a spinning wheel or roller) to cause the metal sheet or tube to undergo plastic deformation, thereby producing axisymmetric parts (such as cylindrical, conical, hemispherical, etc.).

[0003] The existing spinning machines have spinning wheels located on both sides of the main shaft, and their angles are fixed, making it impossible to adjust them according to the shape of the mold during processing. Utility Model Content

[0004] The purpose of this utility model is to provide a spinning device for arc-shaped ring parts. During use, the rotation of the rotating shaft can realize the switching of the pressure rollers and the adjustment of the angle. The slide, together with the standard shaft plate, drives the pressure roller at the front end of the rotating shaft to contact the workpiece. This can improve the adaptability of the device and make it applicable to different scenarios, thus solving the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an arc-shaped ring spinning device, comprising a machine tool, a push rod assembly, a shaping assembly, and a spinning assembly. The shaping assembly includes a housing, and a drive motor is disposed on the top of the housing. A locking shaft is disposed at one end of the drive motor and is rotatably connected to the drive motor. A ball shaft is disposed at the front end of the locking shaft and is connected to the locking shaft by bolts.

[0006] Furthermore, the push rod assembly and the shaping assembly are opposed to each other, and the spinning assembly is located on one side of the shaping assembly.

[0007] Furthermore, a servo motor is provided at one end of the spinning assembly, and a slide is provided above the spinning assembly. A reference plate is provided above the slide, and the reference plate is slidably connected to the slide.

[0018] 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 protection scope of the present utility model.

[0019] To address the issue that existing spinning machines have their spinning wheels located on either side of the main shaft at a fixed angle, making adjustment based on the mold shape during processing; please refer to... Figure 1-3 The present invention provides the following solution:

[0020] See Figure 1A spinning device for arc-shaped ring parts includes a machine tool 1, a push rod assembly 2, a shaping assembly 3, and a spinning assembly 4. The machine tool 1 serves as the main body of the device, providing rigid support to ensure the stability of each component under high pressure and high speed rotation. The shaping assembly 3 includes a housing 301, with a drive motor 302 mounted on top of the housing 301. One end of the drive motor 302 is equipped with a locking shaft 303, which is rotatably connected to the drive motor 302. A ball shaft 304 is mounted at the front end of the locking shaft 303, and the ball shaft 304 is bolted to the locking shaft 303. The push rod assembly 2 and the shaping assembly 3 are opposite to each other, and the spinning assembly 4 is located on one side of the shaping assembly 3.

[0021] In this embodiment, the locking shaft 303 serves as the main drive shaft and is directly connected to the drive motor 302 to transmit rotational power. The ball shaft 304 achieves multi-angle deflection through a universal joint structure, allowing the rotating wheel to feed flexibly on an arc path and adapt to complex curved surface forming.

[0022] See Figure 2 A servo motor 401 is provided at one end of the spinning assembly 4, and a slide 403 is provided above the spinning assembly 4. A reference plate 402 is provided above the slide 403 and is slidably connected to the slide 403. A rotating shaft 404 is provided above one end of the reference plate 402 and is rotatably connected to the reference plate 402. A pressure roller 405 is provided on the outer surface of the rotating shaft 404 and is connected to the rotating shaft 404 by bolts.

[0023] In this embodiment, the surface of the rotating shaft 404 is provided with multiple locking groove structures, which can simultaneously install pressure rollers 405 of different sizes and structures. During use, the rotation of the rotating shaft 404 can realize the switching of pressure rollers 405 and the adjustment of angle. The slide block 403, together with the standard shaft plate 402, drives the pressure roller 405 at the front end of the rotating shaft 404 to contact the workpiece. This can improve the adaptability of the equipment and make it applicable to different scenarios.

[0024] See Figure 3 A support 201 is provided above the push rod assembly 2, serving as the base of the push rod assembly 2 and bearing the installation and load transfer of the hydraulic cylinder 204 and the telescopic push rod 203. The telescopic push rod 203 is provided on one side above the support 201, and the hydraulic cylinder 204 is provided on the other side above the support 201. The hydraulic pressure is controlled by a proportional valve, and the clamping force is dynamically adjusted according to the workpiece material to avoid crushing or slippage. A limit rod 202 is provided below the hydraulic cylinder 204, wherein the limit rod 202 extends to the bottom of the telescopic push rod 203.

[0025] In this embodiment, the workpiece structure is fixed on the surface of the ball bearing 304 by the telescopic push rod 203. The position of the push rod is adjusted in real time during the spinning process to compensate for the workpiece displacement caused by material deformation. The limiting pull rod 202 can limit the maximum extension position of the piston rod of the hydraulic cylinder 204 to prevent over-travel damage to the workpiece or equipment. By connecting the bottom of the hydraulic cylinder 204 and the support, a closed-loop force structure is formed to suppress the elastic deformation of the hydraulic cylinder 204 under high pressure.

[0026] Working principle: The telescopic push rod 203 extends quickly, causing the push rod to initially contact the other end of the workpiece. The hydraulic cylinder 204 is activated, pushing the push rod to apply the main clamping force. At the same time, the limit rod 202 limits the maximum stroke. After the set pressure is reached, the locking mechanism of the limit rod is activated, fixing the position of the push rod. The slide 403, in conjunction with the standard shaft plate 402, drives the pressure roller 405 at the front end of the rotating shaft 404 to contact the workpiece. If the workpiece undergoes slight displacement due to the rotating force, such as local material stretching, the telescopic push rod 203 adjusts the position of the push rod in real time to maintain a balanced clamping force. The hydraulic system dynamically adjusts the pressure according to sensor feedback to avoid excessive clamping force that could cause workpiece deformation. The hydraulic cylinder 204 releases pressure, the locking mechanism of the limit rod 202 is released, the telescopic push rod 203 retracts, and the push rod disengages from the workpiece, completing the unloading.
