Description

Technical Field

[0001] The invention relates to the technical field of commercial wheel processing, in particular to a spinning device for forging and forming a wheel. Background Art

[0002] In wheel manufacturing, forging and spinning technology have become key processes to improve wheel strength and precision. The traditional forging forming process mainly relies on the pressure of the die to press the metal material into shape. Although it has certain strength and durability, the forming process usually requires high energy consumption and complex equipment. Especially when finely forming the wheel, the forming quality is often poor. In order to improve the forming efficiency, spinning forming technology is gradually applied to wheel manufacturing. Spinning is a precision machining technology that gradually deforms the metal blank to form the required contour through the cooperation of the rotating die and the pressure roller.

[0003] However, in the prior art, the spinning equipment generally has the following technical problems: Low processing accuracy: In the existing spinning equipment, the motion trajectory of the pressure roller is difficult to accurately control, resulting in poor surface quality of the wheel after forming, which may be deviated or uneven, affecting the service life of the wheel. Insufficient stability of the mold: During the spinning process, the mold needs to withstand greater pressure, but the mold support in the existing equipment is unstable and prone to shaking, resulting in reduced accuracy during the processing process. High energy consumption: Some spinning equipment requires frequent adjustment of the drive components during operation, resulting in high energy consumption of the equipment and increased production costs. Lack of precise synchronous control: The processes of top pressing and spinning require a high degree of synchronization, but the existing spinning equipment lacks a precise synchronization mechanism, resulting in the inability of the pressure roller to always maintain a consistent pressure with the mold surface during the forming process, affecting the forming quality. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a spinning equipment for wheel forging and forming, so as to improve the forming accuracy, enhance the equipment stability, reduce the energy consumption and optimize the spinning process.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] A spinning device for wheel forging and forming, comprising:

[0007] The base has a mounting groove on the upper part, and a foot is arranged in the mounting groove;

[0008] The driving mechanism is arranged on the base and connected to the foot; the first mold is rotatably mounted on the driving mechanism;

[0009] The pressing mechanism is arranged on the base and connected to the foot; the second mold is rotatably mounted on the pressing mechanism; the axes of the first mold and the second mold are collinear; the pressing mechanism drives the second mold to move along the axis direction of the first mold;

[0010] The spinning mechanism is arranged on the base and connected with the foot; the spinning mechanism is located on the side of the driving mechanism and the top pressing mechanism; it includes a first linear motion module, a second linear motion module, a mounting seat and two pressing rollers; the first linear motion module is connected with the foot, and the second linear motion module is mounted on the first linear motion module; the mounting seat is mounted on the second linear motion module, and the pressing roller is mounted on the mounting seat; the first linear motion module drives the second linear motion module to move along the axis direction parallel to the first mold; the second linear motion module drives the mounting seat to move along the movement direction perpendicular to the first linear motion module;

[0011] The control cabinet is installed on the base and is used to control the operation of the driving mechanism, the pressing mechanism and the spinning mechanism.

[0012] Preferably, the driving mechanism includes a driving bracket, a driving motor and a driving shaft; the driving bracket is mounted on a base; the driving shaft is rotatably mounted on the driving bracket; the driving motor is fixed on the driving bracket and is drivingly connected to the driving shaft; and the first mold is mounted on the driving shaft.

[0013] Preferably, the pressing mechanism includes a third linear motion module, a pressing bracket, a first hydraulic cylinder and a support rod; the third linear motion module is mounted on the base; the pressing bracket is mounted on the third linear motion module; the first hydraulic cylinder is fixed on the pressing bracket; the support rod is connected to the piston rod of the first hydraulic cylinder; and the second mold is rotatably mounted on the other end of the support rod.

[0014] Preferably, the spinning mechanism also includes a second hydraulic cylinder, a connecting rod, a transmission shaft and a turntable; the transmission shaft is rotatably mounted on the mounting seat; the turntable is fixed at one end of the transmission shaft, and the connecting rod is vertically fixed at the other end of the transmission shaft; the second hydraulic cylinder is hingedly mounted on the second linear motion module, and the piston rod of the second hydraulic cylinder is hingedly connected to the connecting rod; the pressure roller is mounted on the turntable.

[0015] Preferably, the pressure roller includes a support frame and a roller; one end of the support frame is fixed on the turntable, and the roller is rotatably installed on the other end of the support frame; one of the rollers of the two pressure rollers is located on one side of the first mold, and the other is located above the first mold.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This equipment adopts the joint design of driving mechanism, pressing mechanism and spinning mechanism. Through the bidirectional adjustment of the first linear motion module and the second linear motion module, the pressing roller can apply uniform pressure to the wheel blank according to the demand, effectively avoiding the problems of uneven surface and uneven material distribution, and improving the accuracy and surface quality of wheel forming.

[0018] The equipment is designed with a driving bracket and a top-pressing bracket, and combined with the stable support of the foot, it ensures that the first and second molds maintain good stability when rotating at high speed.

This synchronous control ensures the coordination of the pressing roller and the die, ensures the uniform distribution of the spinning pressure, avoids the local stress concentration or uneven deformation of the blank during the spinning process, and improves the forming quality and precision of the wheel.

[0021] The precise control of the pressure roller and the two-way motion module enable it to always fit the surface of the wheel blank and form a uniform pressure application. In particular, the two pressure rollers are located on one side and the top of the first mold, respectively, which ensures the uniform force on all parts of the wheel during the forming process, making the wheel surface smooth and flat. In addition, the synchronous control of the drive mechanism and the top pressure mechanism ensures the coordination of various components during the forming process, so that the formed wheel has excellent surface quality and higher structural strength.

[0022] The energy-saving and efficient design of the equipment significantly reduces energy consumption, while reducing the defective rate of forming through the precision control system, saving material costs. In addition, the modular design makes the replacement and maintenance costs of the rollers and molds low, and the equipment can be flexibly adjusted according to the production needs of different wheels, reducing the frequency of equipment updates. Effective cost savings are achieved during long-term operation, which helps to increase production profits. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 3 As shown, a spinning device for wheel forging and forming comprises:

[0030] The base 1 is provided with a mounting groove 10 on the upper part, and a plurality of anchors are provided in the mounting groove 10. Through the fixing of the anchors, the base 1 can stably support the whole device to ensure the stability of each working mechanism. The base 1 is made of high-strength material, which can effectively bear the weight of the driving mechanism, the pressing mechanism and the spinning mechanism, and maintain its stability during operation. In addition, the mounting groove 10 of the base 1 is designed to facilitate the rapid assembly and adjustment of the equipment, and different anchor fixings can be installed as needed to adapt to various ground conditions and improve the versatility of the equipment.

[0031] The driving mechanism is arranged on the base 1 and is firmly connected to the base 1 through the feet, so that the driving mechanism can maintain stability during high-speed rotation. The first mold 5 is rotatably mounted on the driving mechanism to drive the wheel blank to rotate during the spinning process. The close connection between the first mold 5 and the driving mechanism makes the transmission efficiency in the spinning forming higher. The driving mechanism is designed with an adjustable transmission system. Through speed control, the rotation speed of the first mold 5 can be flexibly adjusted according to the blank characteristics and forming requirements to ensure the forming quality of wheel blanks of different thicknesses.

[0032] The pressing mechanism is arranged on the base 1 and connected to the foot to ensure the stability of the equipment during the pressing process. The second mold 13 is rotatably mounted on the pressing mechanism and is kept in line with the axis of the first mold 5 to achieve precise alignment. The pressing mechanism drives the second mold 13 to move along the axis of the first mold 5 through the cooperation of the pressing bracket 9 and the hydraulic cylinder to ensure that the two are always kept on the same axis during the forming process. This design helps to apply uniform pressure to the blank during spin forming, ensures accurate docking between the mold and the blank during the forming process, and improves the flatness and accuracy of wheel forming.

[0033] The spinning mechanism is arranged on the base 1 and connected to the foot to ensure stability and reliability during operation. The spinning mechanism is located on the side of the driving mechanism and the top pressing mechanism, and includes a first linear motion module 7, a second linear motion module 6, a mounting seat 19 and two pressure rollers. The first linear motion module 7 is connected to the foot so that it can provide smooth linear movement during operation; the second linear motion module 6 is installed on the first linear motion module 7, allowing the mounting seat 19 to move accurately along the axis direction parallel to the first mold 5. The mounting seat 19 is installed on the second linear motion module 6, and the pressure roller is installed on the mounting seat 19. The first linear motion module 7 drives the second linear motion module 6 to make the mounting seat 19 move in a direction parallel to the axis of the first mold 5; the second linear motion module 6 drives the mounting seat 19 to translate in a direction perpendicular to the first linear motion module 7, so as to ensure that the pressure roller can flexibly adjust its position and adapt to blanks of different shapes and sizes, thereby improving the flexibility and accuracy of spinning.

[0034] The control cabinet is installed on the base 1 and is used to control the operation of the driving mechanism, the pressing mechanism and the spinning mechanism. The control cabinet is equipped with a programmable controller and a variety of sensor devices, which can accurately control the synchronous operation of each mechanism according to the forming process requirements and adjust various parameters in real time during the operation process to ensure the efficiency and stability of each forming step. The control cabinet also has an operation interface for operators to set parameters, monitor equipment status and perform troubleshooting.

[0035] In this embodiment, the driving mechanism includes a driving bracket 2, a driving motor 3 and a driving shaft 4. The driving bracket 2 is firmly mounted on the base 1 and provides stable support for the driving motor 3. The driving shaft 4 is rotatably mounted on the driving bracket 2 and is in transmission connection with the driving motor 3, thereby providing power for the rotation of the first mold 5. The driving motor 3 adjusts the speed through a frequency conversion controller to meet the forming requirements of different blanks. The first mold 5 is mounted on the driving shaft 4 by bolts or other quick connection devices, so that the operation is convenient and stable when the mold is replaced.

[0036] In this embodiment, the pressing mechanism includes a third linear motion module 11, a pressing bracket 9, a first hydraulic cylinder 8 and a support rod 12. The third linear motion module 11 is mounted on the base 1, and the pressing bracket 9 is fixed on the third linear motion module 11. The first hydraulic cylinder 8 is mounted on the pressing bracket 9, and its piston rod is connected to the support rod 12, and the second mold 13 is mounted on the other end of the support rod 12. Through the telescopic movement of the hydraulic cylinder, the second mold 13 can move freely in the axial direction of the first mold 5 and apply pressure to the blank during the forming process. This structure ensures the precise movement of the second mold 13 at different positions, so that the equipment can adapt to the processing requirements of various wheel sizes.

[0037] In this embodiment, the spinning mechanism also includes a second hydraulic cylinder 16, a connecting rod 17, a transmission shaft 18 and a turntable 20. The transmission shaft 18 is mounted on a mounting seat 19 and can rotate flexibly under the support of the mounting seat 19. The turntable 20 is fixed to one end of the transmission shaft 18, and the connecting rod 17 is vertically connected to the other end of the transmission shaft 18. The second hydraulic cylinder 16 is hingedly mounted on the second linear motion module 6, and its piston rod is connected to the connecting rod 17 by an articulated manner. Through the telescopic movement of the second hydraulic cylinder 16, the connecting rod 17 drives the transmission shaft 18 to rotate, so that the pressure roller on the turntable 20 can contact or disengage from the first mold 5, realizing the conversion of the single pressure roller or double pressure roller mode to meet different wheel forming requirements.

[0038] In this embodiment, the pressure rollers include a support frame 15 and a roller 14. One end of the support frame 15 is fixed on a turntable 20, and the roller 14 is rotatably mounted on the other end of the support frame 15. The rollers 14 of the two pressure rollers are respectively located on one side and above the first die 5, and can apply precise pressure to the wheel blank by rotating and adjusting the position. The bidirectional arrangement of the pressure rollers ensures that the blank is evenly stressed in both the vertical and lateral directions during the forming process, thereby obtaining ideal external dimensions and surface quality during forging.

[0039] How it works

[0040] The spinning equipment mainly realizes the spinning of wheel blanks through the cooperation of driving mechanism, pressing mechanism and spinning mechanism. When working:

[0041] The driving mechanism drives the driving shaft 4 to rotate through the driving motor 3, thereby driving the wheel blank to rotate together with the first mold 5. This high-speed rotation provides the blank with the centrifugal force required for spin forming, and by adjusting the speed of the driving motor 3, it can adapt to wheel blanks of different sizes and materials.

[0042] The pressing mechanism drives the second die 13 to move axially toward the first die 5 through the third linear motion module 11. Under the control of the pressing mechanism, the second die 13 gradually approaches and presses the wheel blank, so that the blank is gradually formed along the die surface during high-speed rotation. The precise control of the first hydraulic cylinder 8 ensures that the second die 13 is always kept in the appropriate position so that pressure is evenly applied during the forming process.

[0043] The double roller design of the spinning mechanism allows the equipment to select a single roller or double roller operation mode according to production requirements. During spinning, the piston rod of the second hydraulic cylinder 16 drives the connecting rod 17 to rotate and control the contact state of the two rollers:

[0044] When the piston rod is pulled back, the connecting rod 17 drives the transmission shaft 18 to rotate, so that the pressure roller located above the first mold 5 is separated from the workpiece, realizing single pressure roller operation, which is suitable for forming smaller-sized blanks.

[0045] When the piston rod is pushed out, the connecting rod 17 enables the two pressing rollers to contact the blank at the same time, realizing double pressing roller operation, which is suitable for providing more uniform and stable forming pressure for blanks of larger sizes.

[0046] The control cabinet is responsible for coordinating the operation of each mechanism, and realizes the precise spinning process by adjusting the action of the drive motor 3, hydraulic cylinder and linear motion module. During the spinning process, the synchronous operation of each mechanism ensures that the blank is gradually formed during the rotation and top pressing process to achieve the ideal size and shape.

[0047] How to use

[0048] Equipment preparation:

[0049] Install the device securely in the work area, making sure that the base 1 is in smooth contact with the ground, and adjust the feet if necessary to keep the device level.

[0050] Select appropriate first mold 5 and second mold 13 according to the specifications of the wheel blank, and install the first mold 5 on the drive shaft 4 and the second mold 13 on the end of the support rod 12 to ensure that the molds are firmly connected.

[0051] Operation parameter settings:

[0052] Open the control cabinet and set the wheel blank processing parameters on the operation interface, including rotation speed, roller contact mode (single roller or double roller), top pressure intensity and the action sequence of each mechanism.

[0053] Select the appropriate roller operation mode according to the size of the blank. If single roller forming is required, set the control cabinet to the pull-back mode of the second hydraulic cylinder 16; if double roller forming is required, set it to the push-out mode.

[0054] Billet loading:

[0055] The wheel blank is fixed to the first die 5, ensuring that the blank is aligned with the die. The blank is locked by a fixing device to prevent it from sliding during the spinning process.

[0056] Start the spinning process:

[0057] The driving mechanism is started, and the driving shaft 4 drives the first die 5 and the blank to rotate.

[0058] The pressing mechanism is started, and the second die 13 gradually moves along the axial direction to start applying pressing force to the blank.

[0059] At the same time, the spinning mechanism is started, the pressure roller contacts the surface of the blank and applies pressure, and driven by the rotation of the driving mechanism, the blank gradually fits the shape of the mold and is formed.

[0060] Spinning:

[0061] During the forming process, the changes in equipment parameters are monitored to ensure the uniformity of pressure and rotation speed. If the forming force or the position of the pressure roller needs to be adjusted, the action of the second hydraulic cylinder 16 can be manually or automatically adjusted through the control cabinet to change the contact state of the pressure roller.

[0062] When the blank is formed to a preset size, the pressing mechanism is stopped, so that the second mold 13 and the pressing roller gradually leave the blank surface.

[0063] Finished product removal:

[0064] The driving mechanism is stopped, and after the blank is completely still, the fixing device is released, and the formed wheel blank is removed from the first mold 5 .

[0065] Check the forming effect of the blank to ensure that the size and shape meet the requirements.

[0066] Equipment cleaning and maintenance:

[0067] Clean the mold and roller after use to avoid processing residues affecting the next use.

[0068] Regularly check the working status of key components such as the hydraulic cylinder, drive motor 3 and transmission shaft 18 to ensure long-term stable operation of the equipment.
