Description

Technical Field

[0001] The present invention relates to the technical field of spinning machines, and particularly to a spinning wheel mechanism and a spinning machine. Background Art

[0002] A spinning machine is a metal plastic forming machine, which is commonly used in the production and processing of devices such as aircraft structural parts, automobile wheel battery casings, and pressure vessels, and has been widely used in various industries such as aerospace, automobile manufacturing, new energy equipment, and shipbuilding.

[0003] In the process of spinning and forming metal products by traditional spinning machines, problems such as workpiece slipping and falling often occur due to the high rotation speed and large processing resistance of the workpiece. Therefore, many spinning machines are equipped with a tailstock mechanism to assist in fixing the workpiece. However, the current tailstock mechanism lacks active equipment, adjustment mechanisms, etc., and its use effect and convenience are insufficient. Moreover, after adding the tailstock mechanism, the spinning wheel mechanism is subjected to large forces, high speeds, and poor lubrication conditions, resulting in a large amount of heat accumulation in the spinning wheel and the spinning wheel shaft during use. If this large amount of heat is not removed in time, it will cause great damage, such as a reduction in bearing life and a decrease in structural strength. At the same time, the increase in the spinning wheel temperature may also transfer heat to the workpiece, resulting in thermal deformation of the workpiece and affecting the processing accuracy. During the spinning process of soft metal materials, hot melt slag may also be generated, and the hot melt slag adheres to the surface of the spinning wheel to form a built-up edge, which in turn affects subsequent production and processing.

[0004] Therefore, there are also spinning wheel mechanisms with a water cooling circulation structure in the prior art. For example, in the solution of the Chinese patent "A Spinning Wheel Structure with Water Circulation" (Application No.: 202420153732.3), a water cooling circulation structure is provided inside the spinning wheel shaft and on the spinning wheel to cool the spinning wheel. However, during the operation of the spinning wheel mechanism, the eccentric or asymmetric cooling water channel structure in the water cooling circulation structure will cause uneven distribution of cooling water in the spinning wheel shaft and the spinning wheel. At the same time, if only relying on adjusting the external water supply device to adjust the cooling water volume, the cooling water volume in the water cooling circulation structure will fluctuate, which will also cause uneven distribution of cooling water in the spinning wheel shaft and the spinning wheel, thereby resulting in the rotational imbalance of the spinning wheel shaft and the spinning wheel, causing circumferential runout, reducing the spinning processing accuracy, and easily damaging the structure of the spinning wheel mechanism.

[0005] It can be seen that there are still certain defects in the prior art. Summary of the Invention

[0006] The purpose of the present invention is to provide a spinning wheel mechanism and a spinning machine to solve at least one of the above technical problems.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions: In a first aspect, the present application provides a roller mechanism, including a roller base, on which a roller shaft is rotatably arranged and the roller shaft penetrates through the roller base. It further includes a roller connected to the roller shaft, a roller gland, and a roller cooling unit. The roller gland is connected to the roller and the roller shaft to lock and fix the roller on the roller shaft. The roller cooling unit includes a circulation flow path arranged inside the roller shaft, a cooling flow path arranged in the roller, and a conduction flow path arranged in the roller gland. The circulation flow path includes a liquid inlet channel and a liquid return channel, and the cooling flow path is communicated with the liquid inlet channel and the liquid return channel through the conduction flow path; It further includes a temperature control component, which includes a first temperature monitoring element for monitoring the temperature of the liquid inside the circulation flow path and the cooling flow path, a second temperature monitoring element for monitoring the surface temperature of the roller, a flow rate monitoring element for monitoring the liquid flow rate inside the cooling flow path, a control valve group for controlling the liquid flow rate inside the cooling flow path, and a controller connected to the first temperature monitoring element, the second temperature monitoring element, the flow rate monitoring element, and the control valve group.

[0008] In the above solution, by setting the roller cooling unit, the roller and the roller shaft can be timely water-cooled during the spinning process, thereby reducing the working temperature of the roller and the roller shaft. It can not only avoid the influence of high temperature on the structural strength of the roller and the roller shaft, but also avoid the transfer of high temperature to the workpiece, resulting in thermal deformation of the workpiece and affecting the processing accuracy. At the same time, it can also avoid the generation of hot melt slag by soft metal materials during the spinning process, and further avoid the formation of built-up edge on the surface of the roller by the hot melt slag, which affects the subsequent production and processing. By setting the temperature control component, it is convenient to accurately adjust the water-cooling flow rate in the above flow path, realize the water volume adjustment on the premise that the cooling water fills the flow path, ensure the cooling effect on the roller, ensure the stability of the roller shaft and the roller during rotation, and at the same time reduce the consumption of water resources.

[0010] Adopting the above two arrangement methods of the liquid inlet channel and the liquid return channel is beneficial to ensuring the uniform distribution of the cooling water inside the roller shaft, avoiding the imbalance and vibration of the roller shaft during rotation caused by uneven overall radial mass distribution of the roller shaft and the cooling water, thereby avoiding the circumferential runout of the roller shaft during the spinning operation and affecting the processing quality.

On the one hand, it is beneficial to keep the inner walls of the flow channels smooth to ensure the improvement of the fluidity of the cooling water to improve the cooling efficiency.

The sealing component forms a water inlet cavity between the inlet liquid ring groove and the swivel shaft, forms a water return cavity between the liquid return ring groove and the swivel shaft, and the water inlet cavity and the water return cavity are isolated from each other.

[0014] As a preferred embodiment of the present application, along the circumferential direction of the swivel shaft, transition grooves are provided on both sides of the orifice edges of the liquid inlet hole and the liquid return hole, and the transition grooves extend along the axial direction of the swivel shaft; along the radial direction of the swivel shaft, the liquid inlet hole and the liquid return hole are oppositely arranged on both sides of the swivel shaft.

[0015] In the above solution, by providing the transition grooves, the rotational resistance of the liquid inlet hole and the liquid return hole in the liquid inside the water inlet cavity and the water return cavity can be reduced, and at the same time, the inflow and outflow speeds of the cooling water through the liquid inlet hole and the liquid return hole can be increased, improving the cooling efficiency.

[0016] As a preferred embodiment of the present application, the cooling flow path includes a first flow path arranged radially close to the inside of the swivel wheel along the swivel wheel and a second flow path arranged close to the edge of the swivel wheel. The first flow path and the second flow path are respectively communicated with the conduction flow path; both the first flow path and the second flow path include at least one annular flow path, and a plurality of the annular flow paths are concentrically arranged and are communicated by radial flow paths between adjacent two of the annular flow paths.

[0017] Adopting the above-mentioned cooling flow path arrangement method can, on the one hand, focus on cooling the part where the edge of the swivel wheel contacts the workpiece to improve the cooling effect, and on the other hand, it can also ensure the uniform distribution of the cooling water inside the swivel wheel to further ensure the stability during the rotation of the swivel wheel and ensure the processing quality.

[0018] As a preferred embodiment of the present application, a first cooling ring groove and a second cooling ring groove are provided on a side of the rotary wheel facing the rotary wheel pressure cover, and the conducting flow path includes a first conducting ring groove and a second conducting ring groove provided on a side of the rotary wheel pressure cover facing the rotary wheel, the first conducting ring groove and the first cooling ring groove correspond to cooperate to form the first flow path, the second conducting ring groove and the first cooling ring groove correspond to cooperate to form the second flow path, and the conducting flow path also includes a docking channel provided in the middle of the rotary wheel pressure cover, and the docking channel is respectively connected to the first flow path, the second flow path and the liquid inlet channel and the liquid return channel.

Specific embodiments

[0025] For a clearer explanation of the overall concept of the present invention, the following will be further described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0026] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0027] In the first aspect, referring to Figures 1 - 4 as shown, the present application provides a rotary wheel 3 mechanism, which includes a rotary wheel base 1, a rotary wheel shaft 2, and a rotary wheel 3 provided on the rotary wheel shaft 2. Specifically, continuing to refer to Figure 1 as shown, the rotary wheel base 1 includes a main body 11, a rear end cover 12 of the rotary wheel base, and a front end cover 13 of the rotary wheel base, and an installation cavity is defined among the three. The rotary wheel shaft 2 is rotatably arranged in the installation cavity through a bearing 15 and penetrates through the installation cavity.

[0028] Further, referring to Figure 1 as shown, the above-mentioned rotary wheel 3 mechanism further includes a rotary wheel gland 4 and a rotary wheel 3 cooling unit. The rotary wheel 3 cooling unit includes a circulation flow path provided inside the rotary wheel shaft 2, a cooling flow path 31 provided on the rotary wheel 3, and a conducting flow path 41 provided on the rotary wheel gland 4. The circulation flow path includes a liquid inlet channel 21 and a liquid return channel 22. Continuing to refer to Figure 1As shown, the spinning wheel gland 4 is fixedly secured to the spinning wheel 3 by bolts. The cooling flow path 31 is clamped between the spinning wheel 3 and the spinning wheel gland 4 and is connected to the liquid inlet passage 21 and the liquid return passage 22 through the conducting flow path 41. It further includes a temperature control assembly, which includes a first temperature monitoring component 82 for monitoring the temperature of the liquid inside the circulation flow path and the cooling flow path 31, a second temperature monitoring component 83 for monitoring the surface temperature of the spinning wheel 3, a flow rate monitoring component 84 for monitoring the flow rate of the liquid inside the cooling flow path 31, a control valve group for controlling the flow rate of the liquid inside the cooling flow path 31, and a controller 81 connected to the first temperature monitoring component 82, the second temperature monitoring component 83, the flow rate monitoring component 84, and the control valve group.

[0029] In the above solution, by providing the spinning wheel 3 cooling unit, the spinning wheel 3 and the spinning wheel shaft 2 can be timely water-cooled during the spinning process, thereby reducing the working temperature of the spinning wheel 3 and the spinning wheel shaft 2. This can not only avoid the influence of high temperature on the structural strength of the spinning wheel 3 and the spinning wheel shaft 2, but also prevent high temperature from being transferred to the workpiece, resulting in thermal deformation of the workpiece and affecting the processing accuracy. At the same time, it can also prevent the generation of hot melt slag during the spinning process of soft metal materials due to high temperature, and further avoid the formation of built-up edge on the surface of the spinning wheel 3 by the attachment of hot melt slag, which affects subsequent production and processing. By providing the temperature control assembly, it is convenient to accurately adjust the water-cooling flow rate, reducing water resource consumption while ensuring the cooling effect on the spinning wheel 3.

[0030] In one example, referring to Figure 1 As shown, the liquid inlet passage 21 and the liquid return passage 22 extend along the axial direction of the spinning wheel shaft 2, and the liquid inlet passage 21 and the liquid return passage 22 are symmetrically arranged around the axis of the spinning wheel shaft 2. In this setting method, the processing method of the liquid inlet passage 21 and the liquid return passage 22 is simple and the maintenance is convenient, which is beneficial to reducing the production cost and the use cost. In another example, referring to Figure 2 As shown, the liquid inlet passage 21 and the liquid return passage 22 are concentrically arranged, and the liquid return passage 22 is sleeved outside the liquid inlet passage 21. Adopting this setting method can fully adapt to the columnar structure of the spinning wheel shaft 2 and make full use of the internal space of the rotating shaft, so as to facilitate expanding the cross-sectional area of the liquid inlet passage 21 and the liquid return passage 22 to increase the flow velocity of the cooling water and thus improve the cooling efficiency on the premise of ensuring the structural strength of the spinning wheel shaft 2.

[0031] Meanwhile, the arrangement modes of the two liquid inlet channels 21 and the liquid return channel 22 in the above examples are both conducive to ensuring the uniform distribution of the cooling water inside the spinning wheel shaft 2, avoiding the imbalance vibration during the rotation of the spinning wheel shaft 2 caused by the uneven radial mass distribution of the spinning wheel shaft 2 and the whole cooling water, thus avoiding the circular runout of the spinning wheel shaft 2 during the spinning operation and affecting the processing quality. At the same time, it is also conducive to reducing the impact on the bearing 15 and prolonging the service life of the bearing 15 and the spinning wheel shaft 2. In the actual application process, the arrangement modes of the liquid inlet channel 21 and the liquid return channel 22 can be comprehensively considered and selected according to factors such as the shaft diameter of the spinning wheel shaft 2, the designed diameters and lengths of the liquid inlet channel 21 and the liquid return channel 22.

[0032] It should be noted here that the arrangement modes of the liquid inlet channel 21 and the liquid return channel 22 in this application are not limited to the above examples. The above examples are only the preferred examples of this application, and it can also adopt other more different arrangement modes such as a symmetric double helix structure, etc. This application does not make specific limitations on this.

[0033] As a preferred embodiment of this application, wear-resistant layers are provided on the inner walls of the liquid inlet channel 21, the liquid return channel 22, the cooling flow path 31 and the conduction flow path 41. Preferably, the wear-resistant layer is made of a tungsten carbide ceramic coating or a nickel-based alloy coating. The wear-resistant layer made of these two materials can withstand both the impact wear and the erosion of the water flow. By providing the wear-resistant layer, the wear of the inner walls of each flow path caused by the flow of the cooling water and the erosion of the inner walls of the above-mentioned flow channels during the rotation of the spinning wheel shaft 2, the spinning wheel 3 and the spinning wheel gland 4 with the cooling water can be reduced. On the one hand, it is conducive to keeping the inner walls of each flow channel smooth to ensure the improvement of the fluidity of the cooling water and thus improve the cooling efficiency. On the other hand, it is conducive to maintaining the uniform radial mass distribution of the spinning wheel shaft 2 and the whole cooling water and ensuring the stable rotation of the spinning wheel shaft 2 and the spinning wheel 3.

[0034] Further, referring to Figure 1 As shown, a liquid inlet hole 23 of the liquid inlet channel 21 and a liquid return hole 24 communicating with the liquid return channel 22 are provided on the spinning wheel shaft 2. An inlet liquid ring groove 111 corresponding to the liquid inlet hole 23 and a return liquid ring groove 112 corresponding to the liquid return hole 24 are provided on the inner wall of the installation cavity. A sealing assembly is further provided between the inner wall of the installation cavity and the spinning wheel shaft 2. The sealing assembly forms a water inlet cavity between the inlet liquid ring groove 111 and the spinning wheel shaft 2, forms a water return cavity between the return liquid ring groove 112 and the spinning wheel shaft 2, and the water inlet cavity and the water return cavity are isolated from each other. Continuing to refer to Figure 1As shown, the sealing assembly includes a plurality of lip-type rotary sealing rings 61. Along the axial direction of the rotary wheel shaft 2, the lip-type rotary sealing rings 61 are arranged at both ends of the liquid inlet annular groove 111 and the liquid return annular groove 112. Preferably, along the circumferential direction of the rotary wheel shaft 2, transition grooves are provided on both sides of the orifices of the liquid inlet hole 23 and the liquid return hole 24. The transition grooves extend along the axial direction of the rotary wheel shaft 2, and along the radial direction of the rotary wheel shaft 2, the liquid inlet hole 23 and the liquid return hole 24 are oppositely arranged on both sides of the rotary wheel shaft 2. In the above solution, by providing the transition grooves, the rotational resistance of the liquid inlet hole 23 and the liquid return hole 24 in the liquid inside the water inlet chamber and the water return chamber can be reduced, and at the same time, the inflow and outflow speeds of the cooling water through the liquid inlet hole 23 and the liquid return hole 24 can be increased, improving the cooling efficiency.

[0035] Further, as a preferred embodiment of the present application, referring to Figure 3 As shown, the cooling flow path 31 includes a first flow path 311 arranged radially close to the inside of the rotary wheel 3 and a second flow path 312 arranged close to the edge of the rotary wheel 3. The first flow path 311 and the second flow path 312 are respectively connected to the conduction flow path 41; both the first flow path 311 and the second flow path 312 include at least one annular flow path, and a plurality of annular flow paths are concentrically arranged and are connected by radial flow paths between adjacent two annular flow paths. By adopting this arrangement of the cooling flow path 31, on the one hand, the part of the edge of the rotary wheel 3 in contact with the workpiece can be focused on cooling to improve the cooling effect, and on the other hand, the distribution of the cooling water inside the rotary wheel 3 can be ensured to be uniform to further ensure the stability of the rotary wheel 3 during rotation and ensure the processing quality.

[0036] In one example, continuing to refer to Figure 3 As shown, on one side of the rotary wheel 3 facing the rotary wheel gland 4, a first cooling annular groove and a second cooling annular groove are provided. The conduction flow path 41 includes a first conduction annular groove 411 and a second conduction annular groove 412 provided on one side of the rotary wheel gland 4 facing the rotary wheel 3. The first conduction annular groove 411 and the first cooling annular groove are correspondingly matched to form the first flow path 311, and the second conduction annular groove 412 and the first cooling annular groove are correspondingly matched to form the second flow path 312. The conduction flow path 41 further includes a docking channel 413 provided in the middle of the rotary wheel gland 4, and the docking channel 413 is respectively connected to the first flow path 311, the second flow path 312, the liquid inlet channel 21, and the liquid return channel 22. The control valve group includes a first control valve 51 and a second control valve 52 provided on the rotary wheel gland 4. The first control valve 51 is correspondingly arranged for the first conduction annular groove 411, and the second control valve 52 is correspondingly arranged for the second conduction annular groove 412. Continuing to refer to Figure 3As shown, the first control valve 51 and the second control valve 52 are both composed of a driving member and a sealing body 53. The sealing body 53 has the same shape as the first conductive ring groove 411 and the second conductive ring groove 412. The sealing body 53 is driven by the driving member to move relative to the rotary wheel 3 along the axial direction of the rotary wheel 3 to change the flow area of ​​the first flow path 311 and the second flow path 312. At the same time, the flow rate and flow rate of the cooling water in the first flow path 311 and the second flow path 312 are controlled by adjusting the water supply speed of the rear-end water supply device, so that the temperature of the rotary wheel 3 can be more flexibly controlled according to the actual processing needs and process requirements to adapt to different processing requirements and improve versatility. At the same time, in the above scheme, the cooling ring groove and the conductive ring groove have simple structures, and the coordination between them and the first control valve 51 and the second control valve 52 is also simple, which is convenient for maintenance and has low use cost.

[0037] Further, refer to Figure 1 and Figure 3 As shown, an O-ring 62 is further provided between the roller cover 4 and the roller 3, and a shock absorbing spacer 63 is further provided between the roller seat body 11 and the roller shaft 2. The shock absorbing spacer 63 is provided to facilitate the installation and fixation of the bearing 15 at the rear end of the roller shaft 2, and on the other hand, it can also provide radial auxiliary support and shock absorbing effects on the roller shaft 2 at the front and rear ends of the roller shaft 2, thereby avoiding the imbalance of the radial support force at the front and rear ends of the roller shaft 2 and absorbing the vibration of the buffering rotating shaft during the rotation process, thereby reducing the circumferential runout of the roller shaft 2 during the rotation process. Figure 1 As shown, a buffer space 14 is left between the middle of the main body 11 of the roller seat 1 and the roller shaft 2. The buffer space 14 can effectively reduce the escape of noise generated by the bearing 15, the roller shaft 2 and the aforementioned lip-shaped rotating seal ring 61 during the rotation inside the installation cavity, thereby reducing noise pollution. At the same time, a certain amount of lubricant such as grease can be stored in the buffer space 14 to lubricate the rotating parts such as the bearing 15, thereby ensuring the normal operation of the roller 3 mechanism.

[0038] Further, refer to Figure 1 As shown, it also includes a pre-rotation drive member 71, which is connected to the end of the rotating wheel shaft 2 away from the rotating wheel 3, and is used to drive the rotating wheel shaft 2 to drive the rotating wheel 3 and the rotating wheel cover 4 to pre-rotate. Figure 1 As shown, the present application adopts a hydraulic motor as a pre-rotation driving member 71. By setting the pre-rotation driving member 71 to drive the pre-rotation of the rotating wheel 3, the material flow trend can be established in advance, and the deformation resistance in the main spinning stage can be reduced, thereby reducing the radial impact when the rotating wheel 3 contacts the workpiece, reducing the bending deflection and runout of the main shaft and the core mold, ensuring the processing quality and processing efficiency, and at the same time helping to extend the service life of the equipment structure such as the main shaft, the core mold and the rotating wheel 3.

[0039] As a preferred embodiment of the present application, a bearing 15 cooling loop is further provided on the part of the spinning wheel shaft 2 corresponding to the installation of the bearing 15. The bearing 15 cooling loop is spirally arranged along the circumferential direction of the bearing 15 mating part inside the bearing 15 mating part, and both ends of the bearing 15 cooling loop are respectively communicated with the liquid inlet channel 21 and the liquid return channel 22. By providing the bearing 15 cooling loop, auxiliary cooling can be provided for the bearing 15, which is beneficial to extending the service life of the bearing 15.

[0040] In a second aspect, the application also provides a spinning machine, which adopts the above-mentioned spinning wheel 3 mechanism. Since the spinning machine includes the above-mentioned spinning wheel 3 mechanism, it also has the beneficial effects of the above-mentioned spinning wheel 3 mechanism. The spinning machine provided by the present invention includes each structure of the spinning mechanism in any of the above embodiments. To avoid repetition, it will not be elaborated here.

It should be noted that the combination of the technical solution of any one embodiment with the technical solutions of one or more other embodiments is within the protection scope of the present invention. Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art.
