Description

Technical Field

[0001] This invention relates to the field of workpiece positioning fixtures, and in particular to a method and apparatus for rapid loading and unloading of high-temperature blanks formed by spinning. Background Technology

[0002] Spinning is a plastic forming method that applies localized pressure to a rotating metal billet using a spinning wheel, gradually shaping it into the desired form. Near-isothermal forging spinning is a newer hot working process that builds upon traditional spinning by applying spinning temperatures close to the material's forging temperature. In this new process, the quality of workpiece clamping directly affects machining accuracy, production efficiency, product quality, and production safety.

[0003] Traditional spinning processes, operating outside of high-temperature environments, rely primarily on manual operation for workpiece positioning. This necessitates manual alignment, multiple adjustments and tightenings, resulting in lengthy processing times, poor repetitive positioning accuracy, and impacted processing quality. Furthermore, the limited applicability of molds, requiring dedicated molds for each drawing number, leads to high costs and long production cycles. Additionally, the lengthy workpiece loading and unloading time results in low production efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problems of traditional spinning processes, such as reliance on manual experience for workpiece positioning, long positioning time, low accuracy, unreliable clamping, poor versatility, long workpiece loading and unloading time, and limited mold applicability, making them unsuitable for workpiece positioning in near-isothermal forging spinning. This invention provides a method and apparatus for rapid loading and unloading of high-temperature blanks formed by spinning, which features fast positioning speed, high accuracy, strong clamping reliability, strong versatility, wide applicability, fast workpiece loading and unloading efficiency, adaptability to high-temperature conditions, and reduced costs.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, the present invention provides a device for rapid loading and unloading of high-temperature spinning blanks, comprising a base plate, a lifting mechanism, and several clamping mechanisms; the base plate is connected to the main shaft of the spinning equipment and rotates synchronously with the main shaft; the lifting mechanism includes a bearing ring and a bearing frame, the bearing frame being connected inside the bearing ring, and several lifting actuators being evenly arranged along the circumference of the bearing ring, the lifting actuators being connected to the base plate and the bearing ring; several positioning rods are slidably connected to the bearing frame, the positioning rods being connected to the base plate, and the axial direction of the positioning rods being arranged along the lifting direction. The support frame is used to place workpieces; the clamping mechanisms are evenly arranged along the circumference of the base plate, and each clamping mechanism includes a slider, a telescopic driver, an adjusting block, and a clamping block. The slider is slidably connected to the base plate, the telescopic driver is connected to the slider and the base plate respectively, the telescopic driver is connected to a pressure sensor, and the telescopic driver can drive the slider to move radially along the base plate. The adjusting block is detachably connected to the slider, and the slider and the adjusting block are configured to adjust their relative positions radially along the base plate. The adjusting block is connected to the clamping block.

[0007] The device for rapid loading and unloading of high-temperature spinning blanks according to the present invention addresses the issue of high-temperature workpieces. By using the slider and the adjusting block to isolate the clamping block and the telescopic actuator, and by using the bearing ring to isolate the support frame and the lifting actuator, the device prevents wear, jamming, or failure of the lifting actuator and the telescopic actuator due to high temperatures. The lifting mechanism allows the workpiece to be raised and lowered to a limit position, enabling the clamping block to hold the workpiece. The positioning rod provides initial positioning of the workpiece, preventing it from being placed too far off-center. The positioning rod also serves as a guide for the lifting of the support frame and ensures that the support frame and the workpiece rotate synchronously with the base plate, preventing the lifting actuator from being subjected to shearing forces. The workpiece is pushed towards the center of the support frame through the synchronous extension and retraction of the clamping mechanism for precise positioning, achieving concentric alignment between the workpiece and the base disc, thus improving positioning accuracy and efficiency. The pressure sensor monitors the clamping force in real time, providing feedback compensation to the telescopic actuator to ensure continuous clamping and uniform force distribution, enhancing clamping reliability. The adjustable relative positions of the slider and the adjusting block allow for changes in the clamping radial dimension, making it suitable for clamping workpieces of different sizes, improving versatility and applicability. No replacement of the clamping blocks is required, reducing mold costs and increasing production efficiency. This device enables fully automated operation, reducing labor costs, operating costs, and safety risks.

The telescopic driver drives the slider to move the clamping block to the initial position, and the lifting driver drives the bearing ring to move the bearing frame to rise. S2. Place the workpiece on the support frame, initially position the workpiece using the positioning rod, and drive the lifting driver to lower the support ring to the limit position. S3.

The telescopic driver drives the slider to move the clamping block to release the workpiece; S6. The lifting driver drives the bearing ring to lift the bearing frame and unload the workpiece.

[0017] The present invention provides a method for rapid loading and unloading of high-temperature spinning blanks. Since the workpiece is a high-temperature component, the slider and adjusting block isolate the clamping block and the telescopic actuator, while the bearing ring isolates the support frame and the lifting actuator, preventing wear, jamming, or failure of the lifting actuator and the telescopic actuator due to high temperatures.

[0027] In related technologies, traditional spinning processes, because they do not operate in high-temperature environments, rely primarily on manual operation for workpiece positioning. This requires manual alignment, multiple adjustments and tightenings, resulting in long processing times, poor repeatability, and reduced positioning accuracy, impacting processing quality. Furthermore, the applicable range of molds is limited, requiring a dedicated mold for each drawing number, leading to high costs and long production cycles. Additionally, long workpiece loading and unloading times result in low production efficiency. Therefore, the technical solution of this application was developed, which is described below in conjunction with... Figures 1 to 7 To elaborate.

[0028] Example 1 like Figures 1 to 7 As shown, the device for rapid loading and unloading of high-temperature blanks formed by spinning according to the present invention includes a base plate 1, a lifting mechanism 2 and a clamping mechanism 3.

[0029] like Figure 1 and Figure 3 As shown, the base plate 1 is connected to the main shaft of the spinning equipment and rotates synchronously with the main shaft.

[0030] like Figure 1 and Figure 2 As shown, the lifting mechanism 2 includes a mounting base 21, a lifting driver 22, a pad 23, a bearing ring 24, a bearing frame 25, and a positioning rod 26.

[0031] like Figure 1 As shown, the mounting base 21 is connected to the base plate 1. The mounting base 21 has a ring-shaped structure, and a plurality of lifting actuators 22 are evenly distributed along the circumference of the mounting base 21. Each lifting actuator 22 is connected to a pad 23, and the pad 23 is connected to the bearing ring 24, so that the lifting actuator 22 is connected between the base plate 1 and the bearing ring 24. In this embodiment, as shown... Figure 2 As shown, four lifting actuators 22 are evenly distributed and connected along the circumference of the mounting base 21.

[0032] like Figure 1 and Figure 2 As shown, the support frame 25 is connected inside the support ring 24, and the support frame 25 is slidably connected with a plurality of positioning rods 26. The positioning rods 26 are connected to the base disc 1, and the axial direction of the positioning rods 26 is arranged along the lifting direction. The support frame 25 is used to place the workpiece 4.

[0033] In one alternative implementation, such as Figure 2 As shown, the support frame 25 includes a central ring 251 and a plurality of support rods 252.

The two ends of the support rods 252 are respectively connected to the central ring 251 and the support ring 24. Each support rod 252 is slidably connected to a positioning rod 26. All the positioning rods 26 are located on a circle concentric with the support ring 24, so that all the positioning rods 26 can define a central range for coarse positioning of the workpiece 4. In this embodiment, as shown... Figure 2 As shown, five bearing rods 252 are evenly arranged around the central ring 251.

[0034] like Figure 1 and Figure 3 As shown, the clamping mechanism 3 includes several components, which are evenly arranged around the base flower plate 1.

[0035] In one alternative implementation, such as Figure 1 As shown, the number of the bearing rods 252 is the same as the number of the clamping mechanisms 3, and one clamping mechanism 3 is provided between two adjacent bearing rods 252.

[0036] like Figure 1 and Figure 3 As shown, each of the clamping mechanisms 3 includes a slider 31, a telescopic driver 32, an adjusting block 33, and a clamping block 34.

[0037] like Figure 1 and Figure 3 As shown, the slider 31 is slidably connected to the base plate 1, and the telescopic actuator 32 is connected to both the slider 31 and the base plate 1. The telescopic actuator 32 is connected to a pressure sensor and can drive the slider 31 to move radially along the base plate 1. By setting the pressure sensor, the clamping force can be monitored in real time, and feedback compensation can be provided to the telescopic actuator 32 to ensure that the clamping block 34 maintains continuous pressure, thereby solving the technical problem of workpiece 4 temperature decreasing, workpiece 4 size shrinking, and clamping force gradually weakening during high-temperature spinning.

[0038] like Figure 3 and Figure 5 As shown, the adjusting block 33 is detachably connected to the slider 31. The slider 31 and the adjusting block 33 are configured to adjust their relative positions radially along the base disc 1. The adjusting block 33 is connected to the clamping block 34. In this embodiment... Figure 6 and Figure 7 As shown, the top surface of the slider 31 is provided with a first rack 312, the length direction of the first rack 312 is arranged radially along the base plate 1, and the mating surface of the adjusting block 33 and the top surface of the slider 31 is provided with a second rack 333. The first rack 312 and the second rack 333 mesh. By adjusting the meshing position of the first rack 312 and the second rack 333, the front and rear positions of the slider 31 and the adjusting block 33 can be adjusted, that is, the relative positions of the slider 31 and the adjusting block 33 along the radial direction of the base plate 1 can be adjusted, so that the size of the area enclosed by all the adjusting blocks 33 can be adjusted, thereby allowing the clamping block 34 to be used to clamp workpieces 4 of different sizes.

[0040] like Figures 5 to 7 As shown, the top of the adjusting block 33 is provided with a protrusion 332, and the bottom of the clamping block 34 is provided with a slot 343. The protrusion 332 is engaged with the slot 343, and the adjusting block 33 and the clamping block 34 are connected by bolts.

[0041] like Figure 4 and Figure 5 As shown, the clamping block 34 includes a first limiting surface 341 and a second limiting surface 342 arranged opposite each other. The workpiece 4 includes a processing area 41 and a clamping area 42. The processing area 41 is connected to the top of the clamping area 42. The clamping area 42 is provided with a step 43. All the clamping blocks 34 are clamped in the clamping area 42. The step 43 is located between the first limiting surface 341 and the second limiting surface 342. With this structural arrangement, the step 43 is limited by the first limiting surface 341 and the second limiting surface 342, ensuring the safety of the spinning process even if the workpiece 4 cools down and shrinks during high-temperature spinning.

[0042] In one optional embodiment, the lifting actuator 22 is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, and the driving direction of the lifting actuator 22 is vertically arranged; the telescopic actuator 32 is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, and the driving direction of the telescopic actuator 32 is radially arranged along the base disc 1.

[0043] In an optional embodiment, the lifting drive 22 and the telescopic drive 32 are respectively connected to displacement sensors for detecting various displacement magnitudes.

[0044] In this embodiment, the device for rapid loading and unloading of high-temperature blanks in spinning has a fast positioning speed, with an automatic positioning time of less than 10 seconds, which is 300% more efficient than manual clamping and positioning; it has high positioning accuracy, with a repeatability of ±0.02mm, meeting the requirements of high-precision spinning processing; it loads and unloads workpieces quickly, improving production efficiency; it clamps reliably, with real-time pressure monitoring and automatic compensation to ensure uniform distribution of clamping force, improving clamping reliability by 50%; it has strong versatility, quickly adapting to workpieces 4 with different diameters (range Φ300mm-Φ2500mm) and different thicknesses (range 25mm-100mm), without the need to change clamping molds, reducing mold costs and improving production efficiency; it has a high degree of automation, with one-button operation, reducing the skill requirements for operators and reducing labor costs; it has good safety, with automatic clamping, eliminating the need for manual operation, reducing safety risks, and real-time monitoring, with automatic alarm and shutdown in case of abnormalities.

[0045] This embodiment describes a device for rapid loading and unloading of high-temperature spinning blanks. Since the workpiece 4 is a high-temperature component, the slider 31 and the adjusting block 33 isolate the clamping block 34 and the telescopic actuator 32, and the bearing ring 24 isolates the support frame 25 and the lifting actuator 22, preventing wear, jamming, or failure of the lifting actuator 22 and the telescopic actuator 32 due to high temperatures. The lifting mechanism 2 allows the workpiece 4 to be raised and lowered to a limit position, enabling the clamping block 34 to hold the workpiece 4. The positioning rod 26 provides initial positioning of the workpiece 4, preventing it from being placed too far off-center. The positioning rod 26 also serves as a guide rod for the lifting of the support frame 25 and ensures that the support frame 25 and the workpiece 4 rotate synchronously with the base plate 1, preventing... The lifting drive 22 is subjected to shearing force; through the synchronous extension and retraction of the clamping mechanism 3, the workpiece 4 is pushed towards the center position of the support frame 25 for precise positioning, realizing that the workpiece 4 and the base plate 1 are concentrically set, improving positioning accuracy and efficiency; by setting the pressure sensor, the clamping force can be monitored in real time, and the extension drive 32 can be fed back for compensation, ensuring that the clamping mechanism 3 continuously clamps the workpiece 4 and that the clamping force is evenly distributed, improving the reliability of clamping; by adjusting the relative position of the slider 31 and the adjusting block 33, the clamping radial dimension of the clamping mechanism 3 can be changed, which is suitable for clamping workpieces 4 of different sizes, improving versatility and applicability, eliminating the need to replace the clamping block 34, reducing mold costs, and improving production efficiency; using this device can achieve fully automated operation, reducing labor costs, lowering operating costs, and reducing safety risks.

[0046] Example 2 like Figures 1 to 7 As shown, the present invention provides a method for rapid loading and unloading of high-temperature spinning blanks, utilizing the apparatus for rapid loading and unloading of high-temperature spinning blanks as described in any of the above claims. The method includes the following steps: Step 1: Based on the size of the workpiece 4 in this batch, adjust and fix the applicable radial dimension of the clamping mechanism 3. That is, by adjusting the meshing position of the first rack 312 and the second rack 333, the relative position of the slider 31 and the adjusting block 33 is adjusted, thereby adjusting the position of the clamping block 34.

[0047] Step 2: After the spinning high-temperature blank rapid loading and unloading device is powered on, the control unit starts the self-test program and controls the telescopic driver 32 to drive the slider 31 to move the clamp 34 back to the initial position (i.e., the maximum opening and closing state). The detection feedback components (including the pressure sensor and the displacement sensor) are calibrated to ensure the accuracy of various detection data. The control unit can be an industrial control computer.

[0048] Step 3: The control unit sends a signal, and the lifting driver 22 drives the support ring 24 to lift the support frame 25. The robot arm takes the workpiece 4 out of the heating furnace and places it on the support frame 25. The positioning rod 26 initially positions the workpiece 4 to prevent it from shifting. The control unit sends a signal, and the lifting driver 22 drives the support ring 24 to lower the support frame 25 to the limit position.

[0049] Step 4: The control unit sends a signal, and the telescopic driver 32 drives the slider 31 to move the clamping block 34 to continuously clamp the workpiece 4 and maintain pressure.

[0050] Step 5: The control unit sends a signal, and the spindle of the spinning equipment rotates, driving the base plate 1 and the workpiece 4 to rotate, and spinning the workpiece 4.

[0051] Step 6: The control unit sends a signal, and the telescopic driver 32 drives the slider 31 to move the clamping block 34 to release the workpiece 4.

[0052] Step 7: The control unit sends a signal, and the lifting driver 22 drives the bearing ring 24 to lift the bearing frame 25, so that the robot arm can unload the workpiece 4.

[0053] This embodiment describes a method for rapid loading and unloading of high-temperature spinning blanks. Since the workpiece 4 is a high-temperature component, the slider 31 and the adjusting block 33 are used to isolate the clamping block 34 and the telescopic actuator 32, and the bearing ring 24 is used to isolate the support frame 25 and the lifting actuator 22, preventing wear, jamming, or failure of the lifting actuator 22 and the telescopic actuator 32 due to high temperatures. The lifting mechanism 2 allows the workpiece 4 to be raised and lowered to a limit position, enabling the clamping block 34 to hold the workpiece 4. The positioning rod 26 provides initial positioning of the workpiece 4, preventing it from being placed too far off-center. The positioning rod 26 also serves as a guide rod for the lifting of the support frame 25 and ensures that the support frame 25 and the workpiece 4 rotate synchronously with the base plate 1, preventing... The lifting drive 22 is subjected to shearing force; through the synchronous extension and retraction of the clamping mechanism 3, the workpiece 4 is pushed towards the center position of the support frame 25 for precise positioning, realizing that the workpiece 4 and the base plate 1 are concentrically set, improving positioning accuracy and efficiency; by setting the pressure sensor, the clamping force can be monitored in real time, and the extension drive 32 can be fed back for compensation, ensuring that the clamping mechanism 3 continuously clamps the workpiece 4 and that the clamping force is evenly distributed, improving the reliability of clamping; by adjusting the relative position of the slider 31 and the adjusting block 33, the clamping radial dimension of the clamping mechanism 3 can be changed, which is suitable for clamping workpieces 4 of different sizes, improving versatility and applicability, eliminating the need to replace the clamping block 34, reducing mold costs, and improving production efficiency; using this device can achieve fully automated operation, reducing labor costs, lowering operating costs, and reducing safety risks.
