Description

Technical Field

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

[0002] In the production process of modern metal gas cylinders, spinning machines not only solve the defects of traditional welding processes through seamless forming, efficient processing and precise control, but also promote the development of gas cylinders towards lightweight, high strength, high pressure resistance and super-large size. As a result, spinning machines have become the core equipment for modern metal gas cylinder manufacturing. However, as gas cylinders develop towards lightweight, high strength, high pressure resistance and super-large size, due to the increasingly higher requirements for the size, strength and material of gas cylinders, traditional processes and spinning machines are gradually unable to meet the production needs of multi-specification, high-strength cylindrical workpieces. The reason is that traditional spinning machines have the following defects:

[0003] 1. Insufficient axial drive stability: Traditional spinning machines typically use only a single motor-screw drive structure to drive the roller frame for axial feed. This is difficult to meet the high axial force requirements of high-strength material processing conditions. This can easily cause vibration or deformation of the roller / roller shaft / spindle structure, affecting processing accuracy and causing damage to the equipment structure.

[0004] 2. Low unloading efficiency: Traditional spinning equipment requires manual loading and unloading or semi-automatic unloading using manually operated unloading tools. This is time-consuming and labor-intensive, impacting processing efficiency and making efficient mass production difficult. Furthermore, because spinning equipment typically adopts an open structure, manual loading and unloading poses significant safety risks.

[0005] 3. Poor spindle connection versatility: The core mold and the spindle are fixedly connected, which makes disassembly and assembly difficult, time-consuming, and labor-intensive. It is also difficult to adapt to products of different sizes, resulting in low equipment utilization and high operating costs.

[0006] To address the above-mentioned shortcomings, new spinning machines exist in the prior art that utilize multiple axial drive mechanisms to enhance axial driving force and stability. For example, the Chinese patent application "A Large Horizontal Spinning Machine Suitable for Long-Distance Spinning" (Application No. 201822092355.4) utilizes at least two screw mechanisms to drive a slide mechanism (i.e., a rotating wheel frame), with the screw mechanisms positioned diagonally relative to the slide mechanism. The addition of these drive mechanisms increases the axial driving force and improves the stability of the rotating wheel frame's axial feed compared to conventional spinning machines. However, the addition of these drive mechanisms also places higher demands on the overall layout of the transmission system. It is necessary to prevent transmission mechanisms (such as ball screws) from interfering with the rotation of the spindle, core mold, and cylindrical workpiece, as well as with the loading and unloading of the cylindrical workpiece. The aforementioned diagonal arrangement poses the risk of interfering with the loading and unloading spaces on either side of the bed. Furthermore, this arrangement places the transmission mechanism's operating position close to the edge of the machine, creating an overly open working environment. This makes the transmission mechanism susceptible to damage from dust, debris, and other interference, while also placing rotating parts too close to the manual operating area, posing a significant safety risk.

[0007] 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 axial direction of the main shaft. 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 main shaft / core mold. The adjustment process in the entire processing is complicated and multiple adjustments are prone to cumulative errors that affect the spinning processing accuracy.

[0008] This shows that the existing technology still has certain defects. Summary of the Invention

[0009] The object of the present invention is to provide a spinning machine to solve at least one of the above technical problems.

[0010] To achieve the above object, the present invention adopts the following technical solutions:

[0011] The present application provides a high-power spinning machine, including 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 main shaft and a main shaft driving device, and also includes a rotating wheel frame driving device, the rotating wheel frame 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, 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 the direction perpendicular to the axial direction of the main shaft, and the plurality of driving units are connected to the rotating wheel frame for driving the rotating wheel frame to reciprocate relative to the bed along the axial direction of the main shaft and drive the rotating wheel frame to deflect relative to the bed around the vertical axis.

[0012] Compared with the existing technology that adopts the single motor + ball screw drive method of the rotary wheel frame, the symmetrically distributed first drive group and the second drive group can effectively improve the stability of the rotary wheel frame during movement, which is beneficial to improving the accuracy of the spinning process.

[0018] In the above scheme, by setting a crossbeam and making the first matching part cooperate with the crossbeam to be connected, the stability of the rotating wheel frame moving along the axial direction of the main shaft can be further improved. Preferably, the lower part of the above-mentioned crossbeam and the upper part of the bed are provided with multiple guide rails extending along the axial direction of the main shaft. The first matching part and the second matching part cooperate with the guide rails and move along the guide rails. The guide rails are preferably I-rails, which have good limiting and guiding functions, and have a simple structure and easy setting, and low use cost and maintenance cost.

[0019] As a preferred embodiment of the present application, the connecting part is capable of rotating around a vertical axis and moving along the width direction of the rotating wheel frame, the first matching part is slidingly matched with the crossbeam through a first sliding member, and the second matching part is slidingly matched with the bed through a second sliding member; the first sliding member is rotationally connected to the first matching part, and the second sliding member is rotationally connected to the second matching part, and the rotating wheel frame is capable of deflecting around the vertical axis relative to the first sliding member and the second sliding member.

[0020] By adopting the above scheme, the overall deflection of the rotating wheel frame can be achieved by rotating and moving the connecting part relative to the first matching part and the second matching part in coordination with the differential between the aforementioned driving parts. The above deflection structure is simple, easy to implement, and highly applicable, and is also suitable for the modification of existing spinning equipment.

[0044] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0045] 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 scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0046] like Figures 1-6As 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 main shaft 21 and a main shaft 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 the direction perpendicular to the axial direction of the main shaft 21, and the plurality of driving units are connected to the rotating wheel frame 3 for driving the rotating wheel frame 3 to reciprocate relative to the bed 1 along the axial direction of the main shaft 21 and to drive the rotating wheel frame 3 to deflect relative to the bed 1 around the vertical axis.

[0047] Compared with the method of using a single motor and a ball screw to drive the rotation of the rotating wheel frame 3 in the prior art, the present application scheme can effectively improve the driving ability of the rotating wheel frame 3 driving device through the symmetrically distributed first drive group and the second drive group, thereby improving the stability of the rotating wheel frame 3 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 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 requirement and space occupancy of a single motor, optimize the equipment structure, reduce equipment cost and maintenance difficulty, and 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 it can better adapt to the processing needs of workpieces of different specifications and shapes.

[0048] In one example, referring to Figure 1-Figure 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; along the 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 rotating wheel frame 3, and the second drive unit 42 and the fourth drive unit 44 are arranged on the same side of the rotating wheel frame 3; along the vertical direction, the upper part of the rotating wheel frame 3 is provided with a first matching portion 31, and the lower part of the rotating wheel frame 3 is provided with a second matching portion 32, the first matching portion 31 is in transmission cooperation with the first drive unit 41 and the second drive unit 42, and the second matching 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 rotating wheel frame 3. The arrangement structure is compact and far away from the manual operation space, which is convenient for setting up protective structures to avoid the influence of debris and can also reduce safety risks. At the same time, in this example, the four drive units are preferably arranged in a symmetrical distribution. This arrangement can further ensure the stability of the rotating wheel frame 3 when it moves. In addition, this arrangement structure is simple, easy to assemble and disassemble, easy to repair and maintain, and can reduce the cost of use and maintenance. For details, 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. The servo motors operate synchronously or asynchronously. It should be noted that the number of drive units provided in this application is not limited to the above example. A setting scheme with more drive units can also be adopted, and this application does not make specific restrictions on this.

[0049] By adopting the above scheme, the synchronous action of each servo motor can ensure that the rotating wheel frame 3 can translate smoothly along the axial direction of the main shaft 21 relative to the bed 1 as a whole, which can meet the spinning process requirements of most workpieces; when the servo motors act asynchronously, such as the servo motors of the first drive unit 41 and the third drive unit 43 maintain synchronous action while acting asynchronously with the servo motors of the second drive unit 42 and the fourth drive unit 44, the differential between the two groups of servo motors can cause a displacement difference on both sides of the rotating wheel frame 3, so that the rotating wheel frame 3 can achieve a certain angle of deflection during the axial movement along the main shaft 21, which is conducive to meeting the spinning processing requirements of workpieces with complex curved surface structures, improving the processing capability and versatility of the high-power spinning machine in this application, and bringing better economic benefits to users.

[0050] Further, as a preferred embodiment of this example, refer to Figure 1-Figure 3 As shown, the high-power spinning machine in the present application is also provided with a crossbeam 11 extending axially along the main shaft 21. The crossbeam 11 is mounted on the upper part of the rotating wheel frame 3. The first matching part 31 is matched and connected with the crossbeam 11, and the second matching part 32 is matched and connected with the bed 1. The first matching part 31 and the second matching part 32 are both provided with a connecting part 33 corresponding to the transmission part 46 (i.e. the aforementioned ball screw), and the nut of the ball screw is connected to the connecting part 33. By setting the crossbeam 11 and making the first matching part 31 match with the crossbeam 11, and matching with the second matching part 32 and the bed 1, the wheel frame 3 can be limited on the upper and lower sides of the wheel frame 3, thereby further improving the stability of the wheel frame 3 moving axially along the main shaft 21. Preferably, the lower part of the crossbeam 11 and the upper part of the bed 1 are provided with a plurality of guide rails 12 extending axially along the main shaft 21. The first matching part 31 and the second matching part 32 match with the guide rails 12 and move along the guide rails 12. The guide rails 12 are preferably I-rails, which have good limiting and guiding functions, simple structure and convenient setting, and low use cost and maintenance cost. It should be noted here that the structure and number of the guide rails 12 in this application are not limited to the above examples. It can also adopt other guide rails 12 with more different structures and different setting methods. This application does not make specific restrictions on this.

[0051] Further, refer to Figure 4As shown, the connecting portion 33 is rotatably matched with the first matching portion 31 and the second matching portion 32, and can rotate relative to the first matching portion 31 and the second matching portion 32 around the vertical axis. At the same time, the first matching portion 31 and the second matching portion 32 are provided with a movable guide groove so that the connecting portion 33 can move along the width direction of the rotating wheel frame 3. Figure 2 、 Figure 3 and Figure 4 As shown, the first mating portion 31 slidably engages with the guide rail 12 at the bottom of the crossbeam 11 via a first sliding member 34, and the second mating portion 32 slidably engages with the guide rail 12 at the top of the bed 1 via a second sliding member 35. The first sliding member 34 is rotatably connected to the first mating portion 31, and the second sliding member 35 is rotatably connected to the second mating portion 32. The roller frame 3 can deflect about a vertical axis relative to the first sliding member 34 and the second sliding member 35. With this solution, the rotation and movement of the connecting portion 33 relative to the first mating portion 31 and the second mating portion 32, in conjunction with the differential between the aforementioned servo motors, can achieve overall deflection of the roller frame 3, ensuring smoothness and stability of the overall rotation of the roller frame 3. Furthermore, the above-described deflection structure is simple, easy to implement, and highly applicable, making it suitable for modification of existing spinning equipment.

[0052] As a preferred embodiment of this application, refer to Figure 4 As shown, a locking assembly is further provided between the connecting portion 33 and the first matching portion 31 and the second matching portion 32. The locking assembly is respectively connected to the first matching portion 31, the second matching portion 32, the first sliding member 34, and the second sliding member 35. The locking assembly has a locking state that limits the deflection of the rotating 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, referring to Figure 4 As shown, the first matching portion 31 and the first sliding member 34 are rotationally matched through the slewing bearing 7, and the second matching portion 32 and the second sliding member 35 are rotationally matched through the slewing bearing 7. The locking assembly includes a locking gear 8 and a gear locking member that cooperates with the locking gear 8. The locking gear 8 is arranged on the side of the slewing bearing 7 and meshes with the gear ring of the outer wall of the slewing support. The gear locking member is a clamp or a claw. The clamp or the claw can be controlled by a hydraulic structure or by manual operation. It should be noted here that the structure and setting method of the locking assembly in this application are not limited to the above examples. The above examples are only preferred examples of this application. It can also adopt other more different structures of anti-rotation parts, limit parts and different settings. This application also does not make specific limitations on this.

[0053] Further, refer to Figure 1-Figure 3As shown, the wheel frame 3 includes a main frame and multiple groups of wheel 36 components arranged on the main frame. The wheel 36 components include wheels 36 and wheel adjustment devices 361 connected to the wheels 36. The wheel adjustment devices 361 drive the wheels 36 to reciprocate relative to the main shaft 21 along the radial direction of the main shaft 21. Figure 1 As shown, in this example, there are four groups of rotating wheel 36 components symmetrically arranged. Setting up four groups of rotating wheel 36 components is beneficial to improving the efficiency and quality of spinning. At the same time, the adjustment of the four groups of rotating wheels 36 through the rotating wheel adjustment device 361 can also better meet the spinning processing needs of different products, and can also better cooperate with the overall deflection of the aforementioned rotating wheel frame 3 to match the spinning processing needs of complex curved surface structure products, further improving the processing capability and versatility of the high-power spinning machine in this application.

[0054] As a preferred embodiment of this application, refer to Figure 1 、 Figure 2 and Figure 5 As 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 main spindle box 2. The automatic unloading device includes a mounting frame 51 and a discharger 52 arranged on the mounting frame 51. The discharger 52 includes a discharge claw 521 and a discharge cylinder 522. The discharge cylinder 522 drives the discharge claw 521 to move relative to the main shaft 21. Preferably, the discharger 52 can also move relative to the mounting frame 51 along the axial direction of the main shaft 21 to better adapt to the unloading requirements of products of different specifications and sizes. By providing 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 the parts, reducing the labor intensity, saving labor costs, and also reducing the safety risks of manual picking up and unloading, which is conducive to ensuring production safety. In addition, automatic unloading shortens the waiting time for picking up and loading, 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 moves with 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, and 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.

[0055] It should be noted here that the structure and layout of the automatic unloading device in this application are not limited to the above examples.

The upper part of the bed 1 is also provided with a tailstock guide slide 63 that cooperates with the tailstock 6. Preferably, refer to Figure 3 As shown, the tailstock guide rail 63 can be shared with the guide rail 12 for guiding the spinning wheel frame 3. This arrangement allows for rapid feed and retraction of the tailstock 6, thereby quickly tightening or releasing the core mold, shortening the non-processing time within a single workpiece processing cycle, and improving the spinning process efficiency. It should also be noted that this application does not specifically limit the structure of the drive device for the tailstock 6. It can adopt the structure in the above example, or other more diverse drive structures and arrangements.
