Description

Technical Field

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

[0002] In the production process of modern metal gas cylinders, spinning machines, through seamless forming, high-efficiency machining, and precise control, not only solve the defects of traditional welding processes but also promote the development of gas cylinders towards lightweight, high-strength, high-pressure resistance, and extra-large sizes. As a result, spinning machines have become the core equipment for modern metal gas cylinder manufacturing. During the development of gas cylinders towards lightweight, high-strength, high-pressure resistance, and extra-large sizes, due to the increasing requirements for the size, strength, material, etc. of gas cylinders, traditional processes and spinning machines are gradually unable to meet the production needs of multi-specification, high-strength cylindrical workpieces. The reasons are as follows: 1. Insufficient axial drive stability: Traditional spinning machines usually only use a single set of motor lead screw drive structures to drive the spinning wheel frame for axial feeding, making it difficult to meet the processing requirements of large axial forces for high-strength materials. This easily causes vibrations or deformations in structures such as the spinning wheel / spinning wheel shaft / spindle, affecting machining accuracy and easily damaging the equipment structure; 2. Low unloading efficiency: Traditional spinning equipment requires manual loading and unloading or a semi-automatic unloading method using manual operation of unloading tools. On the one hand, it is time-consuming and laborious, affecting processing efficiency and making it difficult to achieve high-efficiency batch production. On the other hand, since spinning equipment usually adopts an open structure, the safety risks for manual participation in loading and unloading work are relatively high; 3. Poor universality of spindle connection: The core mold and the spindle are fixedly connected, which is difficult and time-consuming to disassemble and assemble, and it is difficult to adapt to products of different sizes, resulting in low equipment utilization rate and high usage costs.

[0003] In response to the above defects, there are new spinning machines in the prior art that improve axial driving force and stability by setting multiple sets of axial drive mechanisms. For example, in the Chinese patent "A Large Horizontal Spinning Machine Suitable for Long-Distance Spinning" (Application No.: 201822092355.4), at least two lead screw mechanisms are used to drive the slide table mechanism (i.e., the spinning wheel frame), and the lead screw mechanisms are arranged at the diagonal positions of the slide table mechanism. By adding drive mechanisms, compared with traditional spinning machines, the axial driving force is increased and the axial feeding stability of the spinning wheel frame is improved. However, adding drive mechanisms also poses higher requirements for the overall layout method of the transmission system. It is necessary to avoid interference of transmission mechanisms (such as ball screws) with the rotation of the spindle, core mold, and cylindrical workpiece, as well as the loading and unloading of the cylindrical workpiece. The above diagonal arrangement method has a risk of interfering with the loading and unloading space on both sides of the bed, and using the above arrangement method makes the working position of the transmission mechanism close to the edge of the equipment and the working environment too open. On the one hand, it is easily interfered by dust, debris, etc., resulting in damage to the transmission mechanism. On the other hand, the rotating parts are too close to the manual operation space, posing a relatively high safety risk.

[0004] Regardless of whether it is a traditional spinning machine or the new spinning machine with an additional axial drive mechanism, the drive of the spinning wheel frame is limited to the drive in the axial direction of the spindle. When performing spinning processing on complex curved surface structures, the spinning processing needs of the complex curved surface structure can only be met by adjusting the position / angle of the spinning wheel and the installation angle of the workpiece on the spindle / core mold. The adjustment procedures in the entire processing process are complicated and multiple adjustments are prone to cumulative errors that affect the spinning processing accuracy.

[0005] This shows that the prior art still has certain defects. Summary of the invention

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

[0007] To achieve the above object, the present invention adopts the following technical solutions: The present application provides a high-power spinning machine, comprising a bed, a spindle box, a rotating wheel frame and a tail top seat arranged on the bed, the spindle box is provided with a spindle and a spindle driving device, and also comprises a rotating wheel frame driving device, the rotating wheel frame driving device comprises a first driving group and a second driving group, the first driving group and the second driving group are relatively arranged on the upper and lower sides of the rotating wheel frame, the first driving group and the second driving group each comprise a plurality of driving units, and the plurality of driving units are symmetrically distributed along a direction perpendicular to the axial direction of the spindle, the plurality of driving units are transmission-connected with the rotating wheel frame, drive the rotating wheel frame to reciprocate relative to the bed along the axial direction of the spindle and drive the rotating wheel frame to deflect relative to the bed around a vertical axis.

[0008] Compared with the rotary frame driving method of using a single motor + ball screw in the prior art, the symmetrically distributed first drive group and the second drive group can effectively improve the stability of the rotary frame during movement, which is beneficial to improving the accuracy of the spinning process. At the same time, the linkage of multiple drive units can effectively disperse the load. On the one hand, the driving capacity of the rotary frame driving device can be improved to meet the stability requirements under large axial force conditions, adapt to the spinning process needs of higher strength workpieces, improve the spinning process efficiency, and improve the versatility and production efficiency of the high-power spinning machine in this application. On the other hand, it can also reduce the power requirement and space occupancy of a single motor, optimize the equipment structure, and reduce equipment costs and maintenance difficulties. At the same time, by driving the rotary frame to deflect, the flexibility of the spinning process can be improved, and the processing needs of workpieces of different specifications and shapes can be better adapted.

[0009] As a preferred embodiment of the present application, the first driving group includes a first driving unit and a second driving unit, and the second driving group includes a third driving unit and a fourth driving unit; in a direction perpendicular to the axial direction of the main shaft, the first driving unit and the third driving unit are arranged on the same side of the spinning wheel frame, and the second driving unit and the fourth driving unit are arranged on the same side of the spinning wheel frame; in the vertical direction, a first mating part is provided at the upper part of the spinning wheel frame, and a second mating part is provided at the lower part of the spinning wheel frame. The first mating part is in driving cooperation with the first driving unit and the second driving unit, and the second mating part is in driving cooperation with the third driving unit and the fourth driving unit.

[0010] In the above solution, the first driving group and the second driving group are centrally arranged on the upper and lower sides of the spinning wheel frame. The arrangement structure is compact and far from the manual operation space, which is convenient for setting the protection structure to avoid the influence of sundries and can also reduce the safety risk. At the same time, in the above solution, the driving units adopt a symmetric distribution setting method. Using this setting method can further ensure the stability of the spinning wheel frame during movement, and this arrangement structure is simple, easy to load and unload, convenient for maintenance, and can reduce the use cost and maintenance cost.

[0011] As a preferred embodiment of the present application, the first driving unit, the second driving unit, the third driving unit and the fourth driving unit each include an independent driving member and a transmission member, and the driving members act synchronously or asynchronously.

[0012] Adopting the above solution, the synchronous action of the driving members can ensure that the spinning wheel frame moves smoothly along the axial direction of the main shaft relative to the lathe bed, and can meet the spinning process requirements of most workpieces; the asynchronous action of the driving members, such as the driving members of the first driving unit and the third driving unit acting asynchronously with the driving members of the second driving unit and the fourth driving unit, can enable the spinning wheel frame to deflect at a certain angle during the movement along the axial direction of the main shaft, which is beneficial to meeting the spinning processing requirements of workpieces with complex curved surface structures, improving the processing ability and versatility of the power spinning machine in the present application, and bringing better economic benefits to users.

[0013] As a preferred embodiment of the present application, it further includes a cross beam extending along the axial direction of the main shaft. The cross beam is erected on the upper part of the spinning wheel frame. The first mating part is connected to the cross beam in a mating manner, and the second mating part is connected to the lathe bed in a mating manner. Connection parts corresponding to the transmission members are provided on both the first mating part and the second mating part.

[0014] In the above solution, by setting the cross beam and making the first mating part cooperate and connect with the cross beam, the smoothness of the movement of the spinning wheel frame along the axial direction of the main shaft can be further improved. Preferably, a plurality of guide rails extending along the axial direction of the main shaft are provided on the lower part of the cross beam and the upper part of the bed body. The first mating part and the second mating part cooperate with the guide rails and move along the guide rails. The guide rails are preferably I-shaped rails, which have good limiting and guiding effects, simple structures, convenient settings, and low use and maintenance costs.

[0015] As a preferred embodiment of the present application, the connecting part can rotate around the vertical axis and can move in the width direction of the spinning wheel frame. The first mating part is slidably mated with the cross beam through a first sliding member, and the second mating part is slidably mated with the bed body through a second sliding member; the first sliding member is rotatably connected to the first mating part, the second sliding member is rotatably connected to the second mating part, and the spinning wheel frame can deflect relative to the first sliding member and the second sliding member around the vertical axis.

[0016] By adopting the above solution, the differential movement between the connecting part and the first mating part and the second mating part and the foregoing driving members can realize the overall deflection of the spinning wheel frame. Moreover, the above deflection structure is simple, easy to implement, has strong applicability, and is also suitable for the transformation of existing spinning equipment.

[0017] As a preferred embodiment of the present application, a locking assembly is further included. The locking assembly is respectively connected to the first mating part, the second mating part, the first sliding member, and the second sliding member in a cooperative manner. The locking assembly has a locking state that restricts the spinning wheel frame from deflecting relative to the first sliding member and the second sliding member and a release state that allows the first sliding member and the second sliding member to deflect.

[0018] As a preferred embodiment of the present application, the spinning wheel frame includes a main frame and a plurality of sets of spinning wheel assemblies provided on the main frame. The spinning wheel assembly includes a spinning wheel and a spinning wheel adjustment device connected to the spinning wheel. The spinning wheel adjustment device drives the spinning wheel to reciprocate relative to the main shaft in the radial direction of the main shaft.

[0019] As a preferred embodiment of the present application, an automatic unloading device is further included and is provided on one side of the spinning wheel frame facing the main shaft box. The automatic unloading device includes a mounting frame and a unloading device provided on the mounting frame. The unloading device includes a unloading claw and a unloading oil cylinder. The unloading oil cylinder drives the unloading claw to move relative to the main shaft.

[0020] In the above scheme, by setting up an automatic unloading device, the workpiece completed by spinning can be automatically removed from the core mold, eliminating the manual work of picking up parts, reducing labor intensity, saving labor costs, and also reducing the safety risks of manual picking up and unloading, which is beneficial to ensuring production safety. The automatic unloading device shortens the waiting time for picking up and loading materials, which is beneficial to improving production efficiency.

[0021] As a preferred embodiment of the present application, a core mold fixing device is provided on the main shaft, and the core mold fixing device is detachably connected to the core mold.

[0022] Compared with the fixed connection method between the main shaft and the core mold on the traditional spinning machine, the main shaft of the high-power spinning machine in this application can adapt to more core molds of products of different specifications and sizes, thereby greatly improving the versatility and utilization rate of the equipment, reducing the cost of equipment use, improving the economy of use, and creating better economic benefits for users.

[0023] As a preferred embodiment of the present application, it further comprises a tail top seat driving device, which is transmission-connected to the tail top seat and is used to drive the tail top seat to reciprocate relative to the bed along the axial direction of the main shaft.

[0026] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0027] 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 may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 - 6 As shown, the present application provides a high-power spinning machine, including a bed 1, a spindle box 2, a rotating wheel frame 3 and a tail top seat 6 arranged on the bed 1, the spindle box 2 is provided with a spindle 21 and a spindle 21 driving device, and also includes a rotating wheel frame 3 driving device, the rotating wheel frame 3 driving device includes a first driving group and a second driving group, the first driving group and the second driving group are relatively arranged on the upper and lower sides of the rotating wheel frame 3, the first driving group and the second driving group each include a plurality of driving units, and the plurality of driving units are symmetrically distributed along a direction perpendicular to the axial direction of the spindle 21, and the plurality of driving units are transmission-connected with the rotating wheel frame 3, driving the rotating wheel frame 3 to reciprocate relative to the bed 1 along the axial direction of the spindle 21 and driving the rotating wheel frame 3 to deflect relative to the bed 1 around the vertical axis.

[0029] Compared with the method of using a single set of motors and ball screws to drive the rotation of the rotating wheel frame 3 in the prior art, the symmetrically distributed first drive group and second drive group in the present application can effectively improve the driving ability of the rotating wheel frame 3 driving device, thereby improving the stability of the rotating wheel frame 3 when moving, which is beneficial to improving the accuracy of the spinning process. At the same time, the linkage of multiple drive units can effectively disperse the driving load. On the one hand, it can meet the stability requirements under large axial force conditions, adapt to the spinning process needs of higher strength workpieces, improve the spinning process efficiency, and improve the versatility and production efficiency of the high-power spinning machine in this application. On the other hand, it can also reduce the power demand and space occupancy of a single motor, optimize the equipment structure, and reduce equipment costs and maintenance difficulties. At the same time, by driving the rotating wheel frame 3 to do a certain degree of deflection, the flexibility of the spinning process can be improved, and the processing needs of workpieces of different specifications and shapes can be better adapted.

[0030] In one example, referring toFigures 1 - 3 As shown, the first drive group includes a first drive unit 41 and a second drive unit 42, and the second drive group includes a third drive unit 43 and a fourth drive unit 44; in a direction perpendicular to the axial direction of the main shaft 21, the first drive unit 41 and the third drive unit 43 are arranged on the same side of the spinning wheel frame 3, and the second drive unit 42 and the fourth drive unit 44 are arranged on the same side of the spinning wheel frame 3; in the vertical direction, a first mating portion 31 is provided at the upper part of the spinning wheel frame 3, and a second mating portion 32 is provided at the lower part of the spinning wheel frame 3. The first mating portion 31 is in transmission cooperation with the first drive unit 41 and the second drive unit 42, and the second mating portion 32 is in transmission cooperation with the third drive unit 43 and the fourth drive unit 44. In this example, the first drive group and the second drive group are centrally arranged on the upper and lower sides of the spinning wheel frame 3. The arrangement structure is compact and far from the manual operation space, which is convenient for setting up a protection structure to avoid the influence of sundries and can also reduce the safety risk. At the same time, in this example, the four drive units preferably adopt a symmetric distribution setting method. Adopting this setting method can further ensure the stability of the spinning wheel frame 3 during movement, and this arrangement structure is simple, convenient for loading and unloading, and convenient for maintenance, which can reduce the use cost and maintenance cost. Specifically, continue to refer to Figure 1 and Figure 2 As shown, the first drive unit 41, the second drive unit 42, the third drive unit 43, and the fourth drive unit 44 each include an independent drive member 45 and a transmission member 46. Preferably, the drive member 45 is a servo motor, and the transmission member 46 is a ball screw. Each servo motor operates synchronously or asynchronously. It should be noted here that the number of drive units set in this application is not limited to the above example, and a setting scheme with more drive units can also be adopted. This application does not make specific limitations on this.

[0031] Adopting the above solution, the synchronous operation of each servo motor can ensure that the spinning wheel frame 3 moves smoothly along the axial direction of the main shaft 21 relative to the bed body 1, which can meet the spinning process requirements of most workpieces; when the servo motors operate asynchronously, such as when the servo motors of the first drive unit 41 and the third drive unit 43 operate synchronously while operating asynchronously with the servo motors of the second drive unit 42 and the fourth drive unit 44, that is, a displacement difference can occur on both sides of the spinning wheel frame 3 through the differential between the two groups of servo motors, so that the spinning wheel frame 3 can achieve a certain angle of deflection during the movement along the axial direction of the main shaft 21, which is beneficial to meeting the spinning processing requirements of workpieces with complex curved surface structures, improving the processing ability and versatility of the power spinning machine in this application, and bringing better economic benefits to users.

[0032] Furthermore, as a preferred implementation manner of this example, refer to Figures 1 - 3As shown in the figure, the powerful spinning machine in this application is also provided with a cross beam 11 extending along the axial direction of the main shaft 21. The cross beam 11 is erected on the upper part of the spinning wheel frame 3. The first fitting part 31 is connected to the cross beam 11 in a matching manner, and the second fitting part 32 is connected to the bed body 1 in a matching manner. Both the first fitting part 31 and the second fitting part 32 are provided with connecting parts 33 corresponding to the transmission parts 46 (i.e., the aforementioned ball screws). The nut of the ball screw is connected to the connecting part 33. By setting the cross beam 11 and making the first fitting part 31 connected to the cross beam 11 in a matching manner, combined with the connection between the second fitting part 32 and the bed body 1, the spinning wheel frame 3 can be limited on both the upper and lower sides of the spinning wheel frame 3, thereby further improving the smoothness of the axial movement of the spinning wheel frame 3 along the main shaft 21. Preferably, a plurality of guide rails 12 extending along the axial direction of the main shaft 21 are provided on the lower part of the cross beam 11 and the upper part of the bed body 1. The first fitting part 31 and the second fitting part 32 cooperate with the guide rails 12 and move along the guide rails 12. The guide rails 12 are preferably I-shaped rails, which have good limiting and guiding effects, simple structures, convenient settings, and low use and maintenance costs. It should be noted here that the structure and the number of the guide rails 12 in this application are not limited to the above examples, and other guide rails 12 with more different structures and different setting methods can also be used. This application does not make specific limitations on this.

[0033] Further, referring to Figure 4 As shown in the figure, the connecting part 33 is rotationally fitted with the first fitting part 31 and the second fitting part 32, and can rotate relative to the first fitting part 31 and the second fitting part 32 around the vertical axis. At the same time, the first fitting part 31 and the second fitting part 32 are provided with moving guide grooves so that the connecting part 33 can move along the width direction of the spinning wheel frame 3. Continuing to refer to Figure 2 、 Figure 3 and Figure 4 As shown in the figure, the first fitting part 31 is slidably fitted with the guide rail 12 at the lower part of the cross beam 11 through the first sliding part 34, and the second fitting part 32 is slidably fitted with the guide rail 12 at the upper part of the bed body 1 through the second sliding part 35. The first sliding part 34 is rotationally connected to the first fitting part 31, and the second sliding part 35 is rotationally connected to the second fitting part 32. The spinning wheel frame 3 can deflect relative to the first sliding part 34 and the second sliding part 35 around the vertical axis. With the above scheme, through the rotation and movement of the connecting part 33 relative to the first fitting part 31 and the second fitting part 32 and the differential movement between the aforementioned servo motors, the overall deflection of the spinning wheel frame 3 can be realized, and the smoothness and stability of the overall rotation action of the spinning wheel frame 3 can be ensured. At the same time, the above deflection structure is simple, easy to realize, has strong applicability, and is also suitable for the transformation of existing spinning equipment.

[0034] As a preferred embodiment of this application, referring to Figure 4As shown, a locking component is further provided between the connecting portion 33 and the first mating portion 31 and the second mating portion 32. The locking component is respectively connected and mated with the first mating portion 31, the second mating portion 32, the first sliding member 34, and the second sliding member 35. The locking component has a locking state that restricts the deflection of the spinning wheel frame 3 relative to the first sliding member 34 and the second sliding member 35, and a release state that allows the first sliding member 34 and the second sliding member 35 to deflect. In a preferred example, refer to Figure 4 As shown, the first mating portion 31 and the first sliding member 34 are rotationally mated through a slewing bearing 7, and the second mating portion 32 and the second sliding member 35 are rotationally mated through a slewing bearing 7. The locking component includes a locking gear 8 and a gear locking member that mates with the locking gear 8. The locking gear 8 is disposed on the side of the slewing bearing 7 and meshes with the tooth ring on the outer wall of the slewing support. The gear locking member is a clamp or a claw, and the clamp or the claw can be controlled by a hydraulic structure or manually operated. It should be noted here that the structure and setting method of the locking component in this application are not limited to the above example. The above example is only a preferred example of this application, and it can also adopt other more different structures of rotation prevention members, limit members, and different setting methods. This application does not make specific limitations on this either.

[0035] Furthermore, refer to Figures 1 - 3 As shown, the spinning wheel frame 3 includes a main frame and multiple groups of spinning wheel 36 assemblies disposed on the main frame. The spinning wheel 36 assembly includes a spinning wheel 36 and a spinning wheel adjusting device 361 connected to the spinning wheel 36. The spinning wheel adjusting device 361 drives the spinning wheel 36 to reciprocate relative to the main shaft 21 along the radial direction of the main shaft 21. Continuing to refer to Figure 1 As shown, in this example, four groups of spinning wheel 36 assemblies are symmetrically arranged. Arranging four groups of spinning wheel 36 assemblies is beneficial to improving the spinning efficiency and spinning quality. At the same time, the adjustment of the four groups of spinning wheels 36 by the spinning wheel adjusting device 361 can better meet the spinning processing needs of different products, and can also better cooperate with the overall deflection of the aforementioned spinning wheel frame 3 to match the spinning processing needs of products with complex curved surface structures, further improving the processing ability and versatility of the power spinning machine in this application.

[0036] As a preferred implementation manner of this application, refer to Figure 1 、 Figure 2 and Figure 5As shown, the high-power spinning machine in the present application also includes an automatic unloading device arranged on the side of the spinning wheel frame 3 facing the spindle box 2, and the automatic unloading device includes a mounting frame 51 and a discharger 52 arranged on the mounting frame 51, and the discharger 52 includes a discharge claw 521 and a discharge cylinder 522, and the discharge cylinder 522 drives the discharge claw 521 to move relative to the spindle 21. Preferably, the discharger 52 can also move relative to the mounting frame 51 along the axial direction of the spindle 21 to better adapt to the unloading requirements of products of different specifications and sizes. By setting up an automatic unloading device, the workpiece completed by the spinning process can be automatically removed from the core mold, eliminating the manual work of picking up parts, reducing the intensity of manual labor, saving labor costs, and also reducing the safety risks of manual picking up and unloading, which is conducive to ensuring production safety, and automatic unloading shortens the waiting time for picking up parts and loading materials, which is conducive to improving production efficiency. In the above scheme, the automatic unloading device is connected to one side of the rotating wheel frame 3 and follows the rotating wheel frame 3. On the one hand, it is beneficial to improve the matching accuracy between the unloading claw 521 and the workpiece to avoid damage to the spinning product during the unloading process. On the other hand, it also eliminates the need to set up a separate axial drive for the automatic unloading device, which is beneficial to simplify the equipment structure and reduce equipment costs.

[0037] It should be noted here that the structure and arrangement of the automatic unloading device in the present application are not limited to the above examples. The above examples are only preferred examples of the present application. It can also adopt other unloading devices with more different structures and different arrangements. The present application does not make specific limitations on this.

Preferably, the core mold fixing device 211 in the present application is preferably a universal chuck. Compared with the fixed connection between the main shaft 21 and the core mold on the traditional spinning machine, the main shaft 21 of the high-power spinning machine in the present application can be adapted to more core molds of products of different specifications and sizes by adopting the above scheme, thereby greatly improving the versatility and utilization rate of the equipment, reducing the cost of equipment use, improving the economy of use, and creating better economic benefits for users.

[0039] Further, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 6 As shown, the high-power spinning machine in the present application also includes a tail seat 6 driving device, which is connected to the tail seat 6 in a transmission manner and is used to drive the tail seat 6 to reciprocate relative to the bed 1 along the axial direction of the main shaft 21. In one example, the tail seat 6 driving device includes a tail seat servo motor 61, a tail seat reducer 62, and a gear rack transmission mechanism for transmission. The upper part of the bed 1 is also provided with a tail seat guide slide rail 63 that cooperates with the tail seat 6. Preferably, refer to Figure 3As shown, the tailstock guide rail 63 can be shared with the aforementioned guide rail 12 for guiding the spinning wheel frame 3. By adopting this setting method, the rapid feed and rapid retraction of the tailstock 6 can be realized, so that the mandrel can be quickly tightened or released, shortening the non-processing time within the processing cycle of a single workpiece and improving the spinning processing efficiency. It should also be noted here that the present application does not specifically limit the structure of the driving device of the tailstock 6, which can adopt the structure in the above example or other more different driving structures and arrangement methods.
