Description

Technical Field

[0001] This application belongs to the field of spinning technology, specifically relating to an internal and external double spinning device. Background Technology

[0002] Spinning technology, an advanced process for forming metal materials through localized plastic deformation, has been widely used in aerospace, automotive manufacturing, medical devices, and pressure vessels due to its high material utilization, excellent mechanical properties of the formed parts, and suitability for machining complex rotating parts. The core principle of this technology is to fix a metal blank on a mandrel, and then apply continuous pressure to the blank using a spinning tool. Under the constraint of the mandrel, the blank gradually undergoes plastic deformation along a preset trajectory, ultimately forming a part that conforms to the contour of the mandrel. In the development of spinning technology, the spinning process for products usually adopts the "single-side single-tool" mode, that is, only one spinning tool is configured on one side of the product. This tool can either spin the outside of the product or spin the inside of the product. This "single-sided, single-tool" spinning method prevents the inner and outer sides of a product from being spun simultaneously. For products that require both inner and outer shaping, traditional processes can only be performed in stages: first, a spinning tool is used to spin one side of the product; after that side is spun, the spinning tool is changed or the product's clamping position is adjusted to spin the other side. This step-by-step processing method directly leads to low molding efficiency. On the one hand, there is a long interval between the two spinning processes, including tool changes and product adjustments, which significantly extends the processing cycle of a single product. On the other hand, since it is impossible to achieve synchronous spinning on the inside and outside, the coordination of the material during the deformation process is affected, and more spinning cycles may be required to achieve the expected molding effect, further reducing production efficiency. Utility Model Content To address the shortcomings of the prior art, this application provides an internal and external dual spinning device. Through the design of a first spinning component and a second spinning component, the internal and external sides of the product can be spun simultaneously, which greatly reduces processing time, effectively improves molding efficiency, and the simultaneous internal and external spinning can avoid the risk of material deformation, thereby improving processing accuracy.

[0003] The technical effects to be achieved in this application are realized through the following aspects: This application provides an internal and external dual spinning device, comprising: The spinning mechanism includes an X-axis sliding assembly, a first spinning assembly and a second spinning assembly arranged side by side, both of which are movably connected to the X-axis sliding assembly; the gap between the first spinning assembly and the second spinning assembly forms a double spinning operation area; and The main spindle mechanism, located below the spinning mechanism, is used to fix and rotate the product in the double spinning operation area.

[0004] In some implementations, the first spinning assembly and the second spinning assembly have the same structure; The first spinning assembly includes a Y-axis sliding component and a spinning wheel component; one side of the Y-axis sliding component is movably connected to the X-axis sliding component, and its lower end is connected to the spinning wheel component. The Y-axis sliding component is used to control the lifting and lowering of the spinning wheel component.

[0005] In some implementations, the Y-axis sliding component includes a Z-axis slide, an intermediate slide, a third lead screw, and a third motor. The third lead screw is connected to the Z-axis slide and the intermediate slide, and the third motor is driven by the third lead screw. The other side of the intermediate slide is movably connected to the X-axis sliding assembly. The rotating wheel component is located at the lower end of the Z-axis slide.

[0006] In some implementations, the spinning wheel component includes a drive member, a transmission member, a rotating shaft, and a spinning wheel. The drive member is driven to the transmission member, one end of the rotating shaft is connected to the transmission member via a first flat key, and the spinning wheel is connected to the rotating shaft via a second flat key. The drive member is used to drive the rotating shaft to rotate via the transmission member, so as to adjust the deflection angle of the spinning wheel.

[0007] In some implementations, the X-axis sliding assembly includes a first slide table, a first lead screw, a second lead screw, a first motor, and a second motor. The first lead screw and the second lead screw are arranged side by side on the first slide table. The first lead screw is movably connected to the first spinning assembly and is driven by the first motor. The second lead screw is movably connected to the second spinning assembly and is driven by the second motor.

[0008] In some implementations, the X-axis sliding assembly further includes a guide rail connected to the first slide table, and the guide rail is movably connected to both the first spinning assembly and the second spinning assembly.

[0009] In some implementations, the spindle mechanism includes a clamp, a shaft, and a fourth motor. The fourth motor is drivenly connected to the shaft, and the other end of the shaft is connected to the clamp, which is used to fix the product. The fourth motor is used to drive the product in the clamp to rotate through the shaft.

[0010] In some implementations, the clamp is a hydraulic chuck clamp.

[0011] In some implementations, the drive unit includes a fifth motor and a reducer, wherein the drive end of the fifth motor is connected to the input end of the reducer, and the output end of the reducer is connected to the transmission unit.

[0012] In some implementations, the transmission component includes sprockets and chains, with the sprockets connected to the output end of the reducer and one end of the rotating shaft, and the sprockets at both ends connected to the chain.

[0013] In summary, this application has at least the following advantages: The dual spinning device provided in this application fixes the product using a spindle mechanism. An X-axis sliding assembly adjusts the distance between the first and second spinning components until they contact the inner and outer sides of the product respectively. Rotating the product allows for simultaneous spinning of both the inner and outer sides, eliminating the need for tool changes, product adjustments, and multiple spinning adjustments between two spinning processes. This effectively shortens processing time and improves molding efficiency. Furthermore, because it achieves simultaneous spinning of both the inner and outer sides, it effectively reduces the risk of material deformation caused by step-by-step spinning, significantly improving the accuracy of the spinning process.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0021] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0022] Example 1: Please see the appendix Figure 1 The internal and external double spinning device of this application includes a spinning mechanism 1 and a spindle mechanism 2.

[0023] The spinning mechanism 1 includes an X-axis sliding assembly 11, a first spinning assembly 12 and a second spinning assembly 13 arranged side by side, both of which are movably connected to the X-axis sliding assembly 11; the gap between the first spinning assembly 12 and the second spinning assembly 13 forms a double spinning operation area. A spindle mechanism 2 is located below the spinning mechanism 1 and is used to fix and rotate the product 3 within the double spinning operation area.

[0024] The X-axis sliding assembly 11 is used to drive the first spinning assembly 12 and the second spinning assembly 13 to move in the A or D direction.

[0025] In this embodiment, the internal and external spinning device fixes the product 3 to be spun using the spindle mechanism 2, placing the product 3 in the dual spinning operation area. Then, the X-axis sliding assembly 11 adjusts the positions of the first spinning assembly 12 and the second spinning assembly 13 until they abut against the inner and outer sides of the product 3, respectively. The spindle mechanism 2 then rotates the product 3, achieving simultaneous spinning of the inner and outer parts of the product 3. It is understood that the processing path can be directly generated using existing programming software.

[0026] The above technical solution avoids the tool changes, product adjustments, and multiple spinning operations associated with step-by-step spinning of product 3, effectively reducing the processing time for a single product 3. It also enables simultaneous spinning of both the inner and outer sides of product 3, significantly improving spinning efficiency. Furthermore, simultaneous spinning of both the inner and outer sides of product 3 reduces the risk of material deformation caused by multiple spinning operations, thereby effectively improving the precision of the spinning process.

[0027] In this structure, the first spinning assembly 12 and the second spinning assembly 13 are arranged side by side in the X-axis sliding assembly 11, and the product 3 is located below the spinning mechanism 1, which facilitates the spinning of the product 3. The overall structure is compact, has high space utilization, and is easy to produce and install.

[0028] Example 2: The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 2 In this embodiment, the first spinning assembly 12 and the second spinning assembly 13 have the same structure; the first spinning assembly 12 includes a Y-axis sliding component 131 and a spinning wheel component 132; one side of the Y-axis sliding component 131 is movably connected to the X-axis sliding assembly 11, and its lower end is connected to the spinning wheel component 132. The Y-axis sliding component 131 is used to control the lifting and lowering of the spinning wheel component 132.

[0029] In this embodiment, the first spinning assembly 12 and the second spinning assembly 13 move the spinning wheel assembly 132 in the S or W direction via the Y-axis sliding component 131, thereby adjusting the first spinning assembly 12 and the second spinning assembly 13 to a specific height position on the product 3. Real-time adjustments are made in conjunction with the processing path. Through the synchronous rotation of the inner and outer sides of the product 3, the spinning wheel assembly 132 of the first spinning assembly 12 and the spinning wheel assembly 13 enable precise and rapid plastic deformation of the material of the product 3 during the spinning process, ensuring the molding quality of the product 3. It should be noted that since the structure and working principle of the first spinning assembly 12 are the same as those of the second spinning assembly 13, the specific operating logic of the second spinning assembly will not be described further in this application.

[0030] With the above settings, the Y-axis sliding component 131 controls the corresponding height of the spinning wheel components of the first spinning assembly 12 and the second spinning assembly 13 on the product 3. The height of the two spinning wheel components 132 can be adjusted according to the program, which can meet the requirements of high dimensional accuracy products. It not only has a wide range of applications, but also ensures the molding quality of the product 3.

[0031] In some embodiments, see Figure 3 The Y-axis sliding component 131 includes a Z-axis slide 1311, an intermediate slide 1312, a third lead screw 1313, and a third motor 1314. The third lead screw 1313 is connected to the Z-axis slide 1311 and the intermediate slide 1312. The third motor 1314 is driven by the third lead screw 1313. The other side of the intermediate slide 1312 is movably connected to the X-axis sliding assembly 11. The rotating wheel component 132 is located at the lower end of the Z-axis slide 1311.

[0032] Specifically, the Y-axis sliding component 131 is driven by a third motor 1314 to rotate a third lead screw 1313. Since the third lead screw 1313 is connected to the Z-axis slide 1311 and the intermediate slide 1312, the Z-axis slide 1311 moves relative to the intermediate slide 1312 in the S or W direction, thereby driving the spinning wheel component 132 to move at the upper and lower ends of the product 3, completing the spinning operation of the product 3 at different height positions. This structural design is compact and simple, highly practical, and allows for flexible control of the spinning component's position according to the spinning requirements of the product 3.

[0033] In some embodiments, the spinning wheel component 132 includes a drive member 1321, a transmission member 1322, a rotating shaft, and a spinning wheel 1324. The drive member 1321 is drivenly connected to the transmission member 1322, and one end of the rotating shaft is connected to the transmission member 1322 via a first flat key. The spinning wheel 1324 is connected to the rotating shaft via a second flat key; the drive component 1321 is used to drive the rotating shaft to rotate via the transmission component 1322 in order to adjust the deflection angle of the spinning wheel 1324.

[0034] Preferably, the drive component 1321 includes a fifth motor 134 and a reducer 135. The drive end of the fifth motor 134 is connected to the input end of the reducer 135, and the output end of the reducer 135 is connected to the transmission component 1322. The transmission component 1322 includes a sprocket 136 and a chain 137. The sprocket 136 is connected to the output end of the reducer 135 and one end of the rotating shaft, and the sprockets 136 at both ends are connected to the chain 137. One end of the rotating shaft is connected to the sprocket 136 of the transmission component 1322 via a first flat key. The connection ensures stability and guarantees efficient force transmission.

[0035] Specifically, the spinning wheel component 132 has an angle adjustment function. The specific operation process is as follows: the fifth motor 134 drives the reducer 135 to rotate, the reducer 135 drives the sprocket 136 near its side to rotate, and then the chain 137 drives the sprocket 136 connected to the rotating shaft to rotate, thereby driving the rotating shaft to rotate. The spinning wheel 1324 is connected to the rotating shaft via a second flat key, ultimately controlling the rotation of the spinning wheel 1324, allowing it to swing at different spinning angles. This configuration enables the rotating component to swing at different spinning angles to process products, providing high flexibility and allowing for rapid product spinning, effectively improving the adaptability of spinning technology.

[0036] In some embodiments, see Figure 4 The X-axis sliding assembly 11 includes a first slide table 111, a first lead screw 112, a second lead screw 113, a first motor 114, and a second motor 115. The first lead screw 112 and the second lead screw 113 are arranged side by side on the first slide table 111. The first lead screw 112 is movably connected to the first spinning assembly 12 and is driven by the first motor 114. The second lead screw 113 is movably connected to the second spinning assembly 13 and is driven by the second motor 115. The first lead screw 112 is connected to the intermediate slide table 1312 of the first spinning assembly 12, and the second lead screw 113 is connected to the intermediate slide table of the second spinning assembly 13.

[0037] Specifically, the working principle of the X-axis sliding assembly 11 controlling the movement of the first spinning assembly 12 and the second spinning assembly 13 in the A or D direction is as follows: The first motor 114 is started, driving the first lead screw 112 to rotate. Since the first lead screw 112 is connected to the intermediate slide 1312 of the first spinning assembly 12, the first spinning assembly 12 is controlled to move in the A or D direction. Similarly, the second motor 115 is started, driving the second lead screw 113 to rotate. Since the second lead screw 113 is connected to the intermediate slide of the second spinning assembly 13, the second spinning assembly 13 is controlled to move in the A or D direction.

[0038] This configuration allows the X-axis sliding assembly 11 to adjust the distance between the first spinning assembly 12 and the second spinning assembly 13, adapting to spinning products 3 with different thicknesses and specifications, offering high flexibility. Furthermore, the independent movement of the first spinning assembly 12 and the second spinning assembly 13 ensures the independent movement of the two spinning assemblies. This structure also allows for adjustment of the pressure exerted on the product 3 by the first spinning assembly 12 and the second spinning assembly 13, increasing the range of spinning requirements adaptable to the product 3. The independent movement not only improves flexibility but also facilitates subsequent maintenance.

[0039] In some embodiments, the X-axis sliding assembly 11 further includes a guide rail, which is connected to the first slide table 111, and the guide rail is movably connected to the first spinning assembly 12 and the second spinning assembly 13.

[0040] Specifically, the first spinning assembly 12 and the second spinning assembly 13, two different sets of moving bodies, share a common guide rail. This not only ensures the stable movement of the first spinning assembly 12 and the second spinning assembly 13, but also reduces assembly errors between multiple guide rails, ensuring the relative accuracy of the slide table and effectively improving the movement stability of the first spinning assembly 12 and the second spinning assembly 13. At the same time, it requires less processing and equipment investment, effectively reducing equipment manufacturing costs.

[0041] The internal and external spinning device in this embodiment has a compact overall structure and strong practicality. It allows the first spinning assembly 12 and the second spinning assembly 13 to move not only in the S or W direction, but also in the A or D direction. Furthermore, its spinning wheel component 132 can be angle-adjusted, allowing for flexible adjustment of the angle, spacing, pressure, and movement trajectory of the internal and external spinning wheels, resulting in wide adaptability for product 3. In addition, this structure ensures both synchronization and independence among the various components, effectively improving spinning efficiency and ensuring spinning quality.

[0042] Example 3: The difference between this embodiment and Embodiment 2 is that, please refer to... Figure 5 In this embodiment, the spindle mechanism 2 includes a clamp 21, a shaft 22, and a fourth motor 23. The fourth motor 23 is drivenly connected to the shaft 22, and the other end of the shaft 22 is connected to the clamp 21. The clamp 21 is used to fix the product 3. The fourth motor 23 is used to drive the product 3 in the clamp 21 to rotate through the shaft 22. Preferably, the clamp 21 is a hydraulic chuck clamp 21, which can achieve stable fixing of products 3 of different sizes.

[0043] In this embodiment, the main spindle mechanism 2 fixes the product 3 using a hydraulic chuck clamp 21. Then, by starting the fourth motor 23, the shaft 22 rotates, which in turn drives the clamp 21 to rotate, thus rotating the product 3 and performing the spinning operation. This setup ensures stable fixing and smooth rotation of the product 3, guaranteeing stable operation of the spinning process and providing a fundamental guarantee for the quality of the spinning process.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
