Description

Technical Field

[0001] This invention relates to the field of wheel manufacturing and processing technology, specifically to a wheel spinning mold and demolding device. Background Technology

[0002] As a core load-bearing component of a vehicle's driving system, the manufacturing precision and mechanical properties of wheels directly determine a vehicle's driving safety, handling stability, and fuel economy. With the automotive industry's deepening development towards lightweighting, high performance, and energy conservation, aluminum alloys, with their advantages of low density, high specific strength, and good formability, have gradually replaced traditional steel as the mainstream manufacturing material for passenger car and new energy vehicle wheels. Against this backdrop, spinning technology, due to its high material utilization rate, excellent product performance, and high production efficiency, has become one of the core processes in modern aluminum alloy wheel manufacturing. It is widely used in mainstream production routes such as casting + spinning and forging + spinning, driving the transformation of wheel manufacturing from traditional extensive methods to precision near-net-shape forming.

[0003] The core principle of wheel spinning is to fix a cast or forged blank onto a spinning die, and drive the die and blank to rotate synchronously at high speed through a spindle. The spinning wheel feeds gradually along the axial and radial directions, applying local high pressure to the rim area of ​​the blank, causing the metal to undergo continuous plastic deformation and adhere tightly to the die cavity, ultimately forming a rim structure that conforms to the design dimensions and contours. During this process, the metal grains rearrange along the spinning direction to form dense fiber streamlines, increasing the rim strength by more than 30% while achieving a 10%-15% weight reduction effect, perfectly meeting the core requirements of new energy vehicles for reduced unsprung mass and improved range.

[0004] Throughout the industry's development, the technological iteration of spinning dies and demolding devices has consistently kept pace with the evolving needs of the automotive industry. With the rapid expansion of the new energy vehicle market, the demand for large-diameter, thin-walled, and complex-profile wheels continues to grow, driving the development of spinning dies towards higher precision, higher wear resistance, and longer lifespan. Die materials are increasingly adopting high-strength, heat-resistant alloy steel, and processes such as surface nitriding and coating are used to improve wear resistance and anti-sticking properties. Today, wheel spinning dies and demolding devices have become core components of intelligent manufacturing production lines for aluminum alloy wheels. Their technological level directly reflects a country's overall strength in precision manufacturing of automotive parts, providing solid equipment support for the lightweight upgrading and high-quality development of the automotive industry.

[0005] For example, Chinese invention patent application number 20191040 discloses a wheel spinning mold and demolding device, including an upper mold, a connecting sleeve, a slider, a lower mold, and a central connecting block. Multiple identical sliders are connected front to back to form a ring. The sliders are inserted into the annular groove between the side wall of the circular groove at the upper end of the lower mold and the central connecting block. During spinning, the arc-shaped convex edge is engaged at the connection between the outer wheel lip and the wheel rim below the spokes. During demolding, the sliders move up and down together with the wheel blank, solving the problem of reverse demolding at the connection between the wheel rim and the outer wheel lip of cold-spun wheels, eliminating wheel damage caused by demolding, and improving the yield and production efficiency of wheels. This demolding device uses a lifting component and a tray to support the wheel blank, solving the problem of the inability to demold using the central connecting block and the resulting deformation of the wheel blank's front side. However, the device still has certain shortcomings.

[0006] After prolonged use, the molds become damaged, making it difficult to replace them. This hinders the production demands of modern wheel manufacturing, which require high efficiency, low cost, and easy maintenance. It also opposes the trend of rapid model changeover and flexible production in spinning production lines.

[0007] Therefore, we propose a wheel spinning mold and demolding device to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a wheel spinning die and a demolding device to solve the problems mentioned in the background art, such as the inconvenience of replacing the die after long-term use and damage, the difficulty in adapting to the high-efficiency, low-cost, and easy-to-maintain production requirements of modern wheel manufacturing, and the development trend of rapid changeover and flexible production in spinning production lines.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a wheel spinning mold and demolding device, comprising a worktable, a reinforcing base, a ball screw, and a movable block. A reinforcing support frame is installed on the upper surface of the worktable, and a horizontal top plate is installed above the reinforcing support frame. A reinforcing base is installed on the upper surface of the worktable, and a ball screw is installed above the reinforcing base via a bearing seat. A movable block is installed on the ball screw. An upper connecting plate and an upper mold base assembly are provided below the movable block. A drive shaft is installed on the upper surface of the reinforcing base via a bearing seat, and a lower connecting plate is installed at the upper end of the drive shaft. A lower mold base assembly is provided above the lower connecting plate.

[0010] A cross groove is provided on one side of the lower connecting plate and the upper connecting plate, and a snap-fit ​​block is installed on the opposite side of the lower mold base assembly and the upper mold base assembly.

[0011] The upper surface of the equipment's workbench is equipped with an electric slide rail, and a spinning wheel assembly is installed on the electric slide rail.

[0012] Preferably, the horizontal top plate has a clearance groove, the size of which is larger than the size of the second servo motor.

[0013] The above structural design provides space for the second servo motor to move up and down with the movable block, avoiding interference with the horizontal top plate during movement and ensuring the normal lifting and rotation of the upper mold base assembly.

[0014] Preferably, a first servo motor is mounted on the upper surface of the horizontal top plate, and the lower part of the first servo motor is connected to a ball screw via an output shaft.

[0015] With the above structural design, after the first servo motor starts, it drives the ball screw on the reinforced base to rotate through the output shaft. The ball screw drives the movable block and the upper mold base assembly below to rise and fall, thereby clamping or releasing the blank.

[0016] Preferably, a guide rod is installed above the reinforced base, the guide rod passes through the movable block, the movable block and the guide rod are slidably connected, and the guide rod and the ball screw are parallel to each other.

[0017] With the above structural design, when the movable block rises and falls with the ball screw, the guide rod restricts the displacement of the movable block, ensuring that the upper mold base assembly rises and falls smoothly and that the blank is clamped accurately.

[0018] Preferably, a second servo motor is mounted on the upper surface of the movable block, and the lower surface of the second servo motor is connected to the upper connecting plate through an output shaft.

[0019] With the above structural design, after the second servo motor starts, it drives the upper connecting plate and the upper mold base assembly to rotate through the output shaft, thereby driving the blank clamped between the upper mold base assembly and the lower mold base assembly to rotate synchronously, providing rotational power for the spinning processing of the spinning wheel assembly.

[0020] Preferably, the snap-fit ​​block snaps into the cross groove, and the outer end of the snap-fit ​​block is provided with a limit groove. Limit bolts are installed on the outer sides of the upper connecting plate and the lower connecting plate. The center line of the limit bolt coincides with the center line of the limit groove. The position of the spinning wheel assembly is adjustable.

[0021] With the above structural design, tightening the limiting bolts allows the mold base to be quickly fixed and disassembled. The spinning wheel assembly can be adjusted in position via an electric slide rail and can move back and forth to spin the wheel axially and radially.

[0022] Preferably, a movable ring is installed below the lower connecting plate via a telescopic spring, and multiple telescopic springs are distributed in a circular structure.

[0023] With the above structural design, the movable ring moves upward to compress the telescopic spring during demolding. After demolding is completed, the telescopic spring elastically resets, driving the movable ring and the arc block back to their initial positions, preparing for the next demolding.

[0024] Preferably, an arc-shaped block is installed above the movable ring, and arc-shaped grooves are formed on the upper and lower connecting plates. Both the arc-shaped block and the arc-shaped groove are distributed in a circular structure. The arc-shaped block is located inside the arc-shaped groove, and the arc-shaped block and the arc-shaped groove are slidably connected.

[0025] With the above structural design, the movable ring moves upward during demolding, and the arc groove provides guidance for the arc block, ensuring that the arc block smoothly lifts the workpiece along the circumferential direction and avoids uneven deformation of the workpiece due to force.

[0026] Preferably, the front surface of the reinforcing base has an internal groove, and a movable rod passes through the upper part of the internal groove. The movable rod is slidably connected to the reinforcing base, and the lower end of the movable rod is connected to a horizontal plate. The movable rod is located below the movable ring.

[0027] With the above structural design, the horizontal plate moves upward during demolding, simultaneously driving multiple movable rods to lift the movable ring, achieving uniform force application and ensuring smooth demolding.

[0028] Preferably, a first hinge seat is installed on the lower surface of the horizontal plate, and a lever assembly is installed on the first hinge seat. A through groove is opened on the right side of the built-in groove, and the lever assembly moves in the through groove. A second hinge seat is installed above the workbench of the equipment, and the second hinge seat is hinged to the lever assembly. An anti-slip handle is installed on the right side of the lever assembly.

[0029] With the above structural design, when the anti-slip handle is pressed down, the lever assembly rotates in the through groove with the second hinge seat as the fulcrum. The first hinge seat drives the horizontal plate and movable rod to move upward, converting human power into demolding power, achieving labor-saving and efficient demolding, and making the operation simple and convenient.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the wheel spinning mold and demolding device:

[0031] 1. Easy mold replacement and high adaptability

[0032] The upper mold base assembly and the lower mold base assembly can be quickly snapped into the cross grooves of the upper and lower connecting plates via snap-fit ​​blocks. Tightening the limit bolts and embedding them into the limit grooves will fix them in place. Disassembly can be performed by reversing the operation to complete the mold replacement. No complicated tools are required, which greatly shortens the mold change time and adapts to the rapid changeover needs of different wheel specifications, meeting the trend of modern production.

[0033] 2. Spinning process is precise and efficient, ensuring product quality.

[0034] The first servo motor drives the ball screw to move the movable block smoothly up and down along the guide rod, realizing the precise clamping of the blank by the upper and lower die base assemblies; the second servo motor drives the blank to rotate at high speed, and the electric slide rail adjusts the position of the spinning wheel assembly, which can perform precise axial and radial spinning on the wheel; throughout the process, the clamping is stable, the rotation is smooth, and the feed is precise, ensuring the dimensional accuracy and mechanical properties of the wheel profile and improving the finished product qualification rate.

[0035] 3. Easy and smooth demolding, avoiding damage to the workpiece.

[0036] When demolding, pressing down the anti-slip handle causes the lever assembly to rotate around the second hinge, which in turn drives the horizontal plate and movable rod upwards to lift the movable ring via the first hinge. The arc-shaped blocks on the movable ring move smoothly along the arc-shaped groove, evenly lifting the workpiece and achieving effortless demolding. The circumferential distribution design of the arc-shaped blocks avoids uneven force on the workpiece, and the telescopic spring assists in resetting, ensuring smooth demolding while preventing workpiece deformation or scratches.

[0037] 4. Stable and reliable structure with low maintenance costs.

[0038] The reinforced support frame and the reinforced base on the equipment workbench form a stable support system, ensuring that the device does not shake during spinning and demolding. All moving parts adopt a sliding connection design, which reduces wear and makes maintenance easy. The snap-fit ​​structure between the mold and the connecting plate reduces bolt stress, extends the service life of the mold, and reduces the overall maintenance cost of the equipment.

The equipment worktable 1 has a lever assembly 30, a through groove 31, a second hinge seat 32, and an anti-slip handle 33. A reinforcing support frame 2 is installed on the upper surface of the worktable 1, and a horizontal top plate 3 is installed above the reinforcing support frame 2. An obstacle groove 4 is provided on the horizontal top plate 3. The size of the obstacle groove 4 is larger than the size of the second servo motor 10, providing space for the second servo motor 10 to move up and down with the movable block 8, avoiding interference with the horizontal top plate 3 during movement, and ensuring the normal lifting and rotation of the upper mold base assembly 12. A reinforcing base 5 is installed on the upper surface of the worktable 1, and a ball screw 6 is installed above the reinforcing base 5 via a bearing seat. A movable block 8 is installed on the ball screw 6. The upper surface of the horizontal top plate 3... A first servo motor 7 is mounted on the surface. The lower part of the first servo motor 7 is connected to a ball screw 6 via an output shaft. After the first servo motor 7 starts, it drives the ball screw 6 on the reinforced base 5 to rotate via the output shaft. The ball screw 6 drives the movable block 8 and the upper mold base assembly 12 below it to rise and fall, thereby clamping or releasing the blank. A guide rod 9 is mounted above the reinforced base 5, passing through the movable block 8. The movable block 8 and the guide rod 9 are slidably connected. The guide rod 9 and the ball screw 6 are parallel to each other. When the movable block 8 rises and falls with the ball screw 6, the guide rod 9 restricts the displacement of the movable block 8, ensuring smooth rising and falling of the upper mold base assembly 12 and accurate clamping of the blank. The upper surface of the movable block 8 is equipped with a second servo motor 10, and the lower surface of the second servo motor 10 is connected to the upper connecting plate 11 through the output shaft. After the second servo motor 10 is started, it drives the upper connecting plate 11 and the upper mold base assembly 12 to rotate through the output shaft, thereby driving the blank clamped between the upper mold base assembly 12 and the lower mold base assembly 15 to rotate synchronously, providing rotational power for the spinning processing of the spinning wheel assembly 21. The upper connecting plate 11 and the upper mold base assembly 12 are arranged below the movable block 8. The upper surface of the reinforcing base 5 is equipped with a transmission shaft 13 through a bearing seat, and the upper end of the transmission shaft 13 is equipped with a lower connecting plate 14. The lower mold base assembly 15 is arranged above the lower connecting plate 14.

[0052] A cross groove 16 is provided on the opposite side of the lower connecting plate 14 and the upper connecting plate 11.

A limit groove 18 is provided on the outer end of the snap-fit ​​block 17. A limit bolt 19 is installed on the outer side of the upper connecting plate 11 and the lower connecting plate 14. The center line of the limit bolt 19 coincides with the center line of the limit groove 18. The position of the spinning wheel assembly 21 is adjustable. Tightening the limit bolt 19 makes it embed into the limit groove 18, realizing quick fixing and disassembly of the mold base. The spinning wheel assembly 21 can be adjusted in position and moved back and forth by the electric slide rail 20 to spin the wheel axially and radially.

[0053] An electric slide rail 20 is installed on the upper surface of the equipment workbench 1, and a spinning wheel assembly 21 is provided on the electric slide rail 20.

[0054] A movable ring 23 is installed below the lower connecting plate 14 via a telescopic spring 22. Multiple telescopic springs 22 are arranged in a circular structure. During demolding, the movable ring 23 moves upward to compress the telescopic spring 22. After demolding, the telescopic spring 22 elastically resets, causing the movable ring 23 and the arc-shaped block 24 to return to their initial positions, preparing for the next demolding. An arc-shaped block 24 is installed above the movable ring 23. Arc-shaped grooves 25 are formed on the upper connecting plate 11 and the lower connecting plate 14. Both the arc-shaped block 24 and the arc-shaped groove 25 are circular in structure. The arc-shaped block 24 is located inside the arc-shaped groove 25, and there is a sliding connection between the arc-shaped block 24 and the arc-shaped groove 25. During demolding, the movable ring 23 moves upward, and the arc-shaped groove 25 provides guidance for the arc-shaped block 24, ensuring that the arc-shaped block 24 smoothly lifts the workpiece along the circumferential direction, avoiding uneven deformation of the workpiece. An internal groove 26 is formed on the front surface of the reinforcing base 5, and a movable rod 27 passes through the upper part of the internal groove 26. The movable rod 27 connects to the reinforcing base 5. The fixed bases 5 are slidably connected. The lower end of the movable rod 27 is connected to the horizontal plate 28. The movable rod 27 is located below the movable ring 23. When demolding, the horizontal plate 28 moves upward, which simultaneously drives multiple movable rods 27 to lift the movable ring 23, so as to achieve uniform force and ensure smooth demolding. The lower surface of the horizontal plate 28 is equipped with a first hinge seat 29, and a lever assembly 30 is installed on the first hinge seat 29. A through groove 31 is opened on the right side of the built-in groove 26. The lever assembly 30 moves in the through groove 31. A second hinge seat 32 is installed above the worktable 1 of the equipment. The second hinge seat 32 is hinged to the lever assembly 30. An anti-slip handle 33 is installed on the right side of the lever assembly 30. When the anti-slip handle 33 is pressed down, the lever assembly 30 rotates in the through groove 31 with the second hinge seat 32 as the fulcrum. The first hinge seat 29 drives the horizontal plate 28 and the movable rod 27 to move upward, converting human power into demolding power, realizing labor-saving and efficient demolding, and making the operation simple and convenient.

[0055] It should be noted that the spinning wheel assembly 21 in this application is a commonly used technical structure in the field, and its internal mechanism and working principle will not be described in detail here.

[0056] Working principle: When using this wheel spinning die and demolding device, firstly, the die is installed and replaced: the snap-fit ​​block 17 of the upper die base assembly 12 is snapped into the cross groove 16 of the upper connecting plate 11, and the snap-fit ​​block 17 of the lower die base assembly 15 is snapped into the cross groove 16 of the lower connecting plate 14. The limiting bolts 19 on the outer side of the upper connecting plate 11 and the lower connecting plate 14 are tightened so that they are embedded in the limiting groove 18 of the snap-fit ​​block 17, thus completing the die fixing; when replacing, the limiting bolts 19 are loosened in the opposite direction, and the die can be quickly removed to adapt to the processing of wheels of different specifications.

[0057] Blank clamping: The wheel blank is placed on the lower mold base assembly 15. The first servo motor 7 on the horizontal top plate 3 is started. Its output shaft drives the ball screw 6 on the reinforced base 5 to rotate. The movable block 8 slides smoothly down along the guide rod 9, driving the upper connecting plate 11 and the upper mold base assembly 12 to move down synchronously until the upper mold base assembly 12 is in contact with the upper surface of the blank, thus achieving precise clamping of the blank. The clearance groove 4 on the horizontal top plate 3 provides lifting space for the second servo motor 10 to avoid interference.

[0058] Spin forming: Start the second servo motor 10 on the movable block 8. Its output shaft drives the upper connecting plate 11, the upper mold base assembly 12 and the blank to rotate. At the same time, start the electric slide rail 20 on the equipment worktable 1 and adjust the position of the spinning wheel assembly 21 so that the spinning wheel assembly 21 is in contact with the surface of the blank. During the spinning process, the spinning wheel assembly 21 can move along the electric slide rail 20 and move back and forth on its own to perform axial and radial composite spinning on the blank, so that the blank is tightly attached to the mold cavity to form a wheel contour.

[0059] Upper mold demolding: After spinning is completed, the first servo motor 7 is started in reverse, and the ball screw 6 drives the movable block 8 and the upper mold base assembly 12 to move upward. At the same time, the second servo motor 10 keeps rotating, so that the upper mold base assembly 12 rotates away from the workpiece to avoid sticking to the workpiece and achieve smooth demolding of the upper mold.

[0060] Lower mold demolding: Press down on the anti-slip handle 33 on the right side of the lever assembly 30. The lever assembly 30 rotates within the through groove 31 with the second hinge seat 32 as the fulcrum, driving the horizontal plate 28 and the movable rod 27 upward through the first hinge seat 29. The movable rod 27 pushes the movable ring 23 to compress the telescopic spring 22. The arc-shaped block 24 on the movable ring 23 moves smoothly upward along the arc groove 25 of the lower connecting plate 14, evenly lifting the workpiece and completing the lower mold demolding. After releasing the anti-slip handle 33, the telescopic spring 22 elastically resets, driving the movable ring 23, arc-shaped block 24, etc., back to their initial positions, preparing for the next processing, thus completing a series of operations. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
