Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a blanking module for a stamping equipment. Background Technology

[0002] As the core load-bearing component of automobile wheels, wheel rims require multiple stamping processes during production. The stability and efficiency of the material cutting process directly affect the product qualification rate and production cycle.

[0003] However, traditional stamping equipment's stamping die base only performs the stamping forming function and lacks an integrated blanking guide structure. After stamping, the wheel hub often adheres to the lower die surface or gets stuck in the gap between the upper and lower dies due to stamping stress. Manual assistance with tools such as pry bars and hooks is required for blanking, which is not only labor-intensive and inefficient, but also prone to edge deformation and surface scratches due to uneven manual operation, reducing product yield. Although some equipment is equipped with an ejector rod structure to push the wheel hub upwards through the ejector rod inside the lower die, the wheel hub still needs to be manually transferred after ejection, making automated continuous blanking impossible.

[0004] On the other hand, existing automated unloading mechanisms (such as robotic arms and adsorption devices) are complex in structure and expensive. Robotic arm unloading requires precise positioning components, and needs to be readjusted when adapting to different specifications of wheel hubs, resulting in poor compatibility. It also occupies space around the equipment and affects the layout of the production line. Vacuum adsorption unloading is affected by the flatness of the wheel hub surface, resulting in insufficient adsorption stability and a risk of workpiece falling off. In addition, it requires an additional vacuum system, which results in high energy consumption and maintenance costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a blanking module for a stamping equipment.

[0006] To address the aforementioned issues, traditional stamping equipment's stamping die base only performs the stamping forming function and lacks an integrated blanking guidance structure. After stamping, the wheel hub often adheres to the lower die surface or gets stuck in the gap between the upper and lower dies due to stamping stress. Manual assistance with tools such as pry bars and hooks is required for blanking, which is not only labor-intensive and inefficient but also prone to edge deformation and surface scratches due to uneven manual operation, reducing product yield. While some equipment is equipped with an ejector rod structure to push the wheel hub upwards through the ejector rod inside the lower die, the wheel hub still needs to be manually transferred after ejection, making automated continuous blanking impossible. Furthermore, existing automated blanking mechanisms are complex and costly. The robotic arm unloading method requires precise positioning components, and needs to be readjusted when adapting to different specifications of wheel hubs, resulting in poor compatibility. It also occupies space around the equipment, affecting the production line layout. Vacuum adsorption unloading is affected by the flatness of the wheel hub surface, resulting in insufficient adsorption stability and a risk of workpiece detachment. Furthermore, it requires an additional vacuum system, leading to high energy consumption and maintenance costs. The technical solution adopted in this invention is: A blanking module for a stamping machine includes a stamping machine body, an upper die holder, and a stamping base, comprising: An adjusting shaft is provided on both sides of the lower end of the stamping seat.

A guide slide bar is disposed inside the horizontal slide bar and is used to lift and unload the stamped car wheel hub. A support spring is disposed inside the vertical slide bar, and the side end of the support spring is connected to the outer end of the guide slide bar to provide continuous elastic support force for the guide slide bar.

[0007] Preferably, an adjusting seat is provided on the front side of the lower end of the stamping seat, and an adjusting groove is provided at the lower end of the adjusting seat. An adjusting screw is rotatably connected to the middle of the adjusting groove. Adjusting sliders are threaded to the outer curved surfaces on both sides of the adjusting screw. A connecting rod is rotatably connected to the lower end of the adjusting slider. The outer side of the connecting rod is rotatably connected to the adjusting rod. The adjusting rod is connected to the adjusting shaft.

[0008] Preferably, the adjusting screw adopts a bidirectional trapezoidal thread design with opposite thread directions at both ends. The adjusting slider slides in cooperation with the inner wall of the adjusting groove, and guide bosses are provided on both sides of the slider. An adjusting motor is provided at the lower end of the stamping seat. The output shaft of the adjusting motor is keyed to a first synchronous pulley. The outer end of the first synchronous pulley is connected to a second synchronous pulley via a synchronous belt drive. The second synchronous pulley is keyed to the outer end of the adjusting screw.

[0009] Preferably, a limiting horizontal groove is provided on the side end of the support platform, a horizontal lead screw is rotatably connected to the middle of the horizontal groove, a horizontal slider is threaded to the outer curved surface of the middle of the horizontal lead screw, and the extension frame is set at the bottom of the horizontal slider.

[0010] Preferably, the outer surfaces of the guide slide and the horizontal slide are coated with a lubricating coating, and the inner surface of the guide slide is provided with an elastic buffer pad to prevent edge damage.

[0011] Preferably, the main body of the stamping equipment includes a stamping base, with columns installed at the four corners of the upper end of the stamping base, a top seat at the upper end of the columns, and a hydraulic telescopic cylinder in the middle of the top seat. The stamping base is connected to the telescopic piston rod at the lower end of the hydraulic telescopic cylinder.

[0012] Preferably, the four corners of the stamping base are provided with guide holes that slide with the outer curved surface of the upper end of the column. The upper die base is provided on the lower end face of the stamping base. The upper middle part of the stamping base is provided with a lower die base. The upper end of the lower die base is provided with a positioning groove for fitting and positioning the automobile wheel hub to be stamped.

[0013] Preferably, four vertical slide rods are symmetrically arranged on the upper end of the stamping base, and a slide tube is arranged at the corresponding position on the lower end of the stamping base. The vertical slide rods and the slide tube are coaxially arranged for secondary linear vertical positioning of the stamping base.

[0014] Preferably, two adjustment shafts are provided, symmetrically distributed with the vertical center line of the stamping seat as the axis of symmetry. The vertical lead screw adopts a trapezoidal thread structure, and the upper end of the vertical lead screw is rotatably connected to the bottom of the vertical slider to support the vertical slider.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention requires no additional drive unit and is directly integrated into the stamping base. It achieves synchronized material feeding through the up-and-down stroke of the stamping base, simplifying the overall equipment structure, reducing manufacturing costs and maintenance difficulty. It can be directly adapted to the upgrading of existing stamping equipment without requiring production line reconstruction. The triangular guide slide bar and the car wheel hub have surface contact, resulting in even force distribution. This effectively avoids workpiece deformation and scratches caused by traditional top-loading structures. Combined with the smooth transition design of the wedge-shaped end and the elastic buffer pad, it further protects the quality of the wheel hub edge and improves the product qualification rate.

[0017] This invention also enables simultaneous completion of stamping and blanking processes, requiring no manual intervention throughout the entire process, significantly shortening the production cycle. Simultaneously, the use of servo motors and bidirectional lead screws allows for rapid adjustment of guide rod parameters, reducing changeover time by over 90% and accommodating the processing needs of different specifications of annular wheel hubs. Blanking is achieved solely through the elastic potential energy of the support spring and the workpiece's gravity, with no additional energy consumption. Combined with self-lubricating coatings and wear-resistant guide sleeves, component wear is reduced, extending module lifespan and effectively lowering production line energy consumption and operating costs.

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0022] Please see Figures 1-6 This embodiment proposes a blanking module for a stamping equipment, including a stamping equipment body 1 and an upper die holder 2. The upper die holder 2 is fastened to the stamping execution part of the stamping equipment body 1 by high-strength bolts, ensuring that the upper die holder 2 can move stably up and down in a straight line with the stamping part of the stamping equipment body 1 to accurately complete the stamping action.

[0023] The main body 1 of the stamping equipment includes a stamping base 101. Columns 102 are fixedly mounted at the four corners of the upper end of the stamping base 101 using high-strength nuts. The columns 102 are made of seamless steel pipe and possess excellent bending strength. The upper end of the columns 102 is fastened to a top seat 103 via flange nuts. A hydraulic telescopic cylinder 104 is fixedly mounted in the middle of the top seat 103 via screws. The hydraulic telescopic cylinder 104 is a high-pressure heavy-duty model, and a stamping seat 105 is mounted on its lower telescopic piston rod via a connecting flange and bolts. Guide holes are provided at the four corners of the stamping seat 105. These guide holes slide against the outer curved surface of the upper end of the columns 102, achieving vertical sliding limit of the stamping seat 105 and ensuring no deviation during the stamping process. An upper die seat 2 is bolted to the lower end face of the stamping seat 105. A lower die holder 3 is mounted on the upper center of the stamping base 101 via positioning bolts. The upper end of the lower die holder 3 is fitted with a positioning groove for mounting and positioning the automobile wheel hub 4 to be stamped. Through precise mold closing between the upper die holder 2 and the lower die holder 3, the stamping forming of the automobile wheel hub 4 is completed. To further improve the motion accuracy of the stamping base 105, four vertical slide rods 106 are symmetrically mounted on the upper end of the stamping base 101. A slide tube 107 is bolted to the corresponding position on the lower end of the stamping base 105. The vertical slide rods 106 and the slide tube 107 are coaxially arranged, and a wear-resistant copper sleeve is embedded in the inner wall of the slide tube. Through the sliding cooperation of the two, the stamping base 105 achieves secondary linear vertical limiting, effectively counteracting the lateral force during the stamping process.

[0024] Two adjusting shafts 5 are rotatably connected to the lower ends of the stamping base 105 via bearings. These shafts are symmetrically distributed about the vertical center line of the stamping base 105. A support platform 6 is connected to the middle of the adjusting shafts 5 via a key. Extension frames 7 are installed on both sides of the lower end of the support platform 6. The extension frames 7 are integrally cast from cast steel, resulting in high structural strength. A vertical slide groove 8 is formed through the middle of the extension frame 7, and a vertical slider 9 is slidably connected to the inner wall of the vertical slide groove 8. A vertical lead screw 10 is threadedly connected to the bottom of the extension frame 7. The vertical lead screw 10 uses a trapezoidal thread structure and has a self-locking function. Its upper end is rotatably connected to the bottom of the vertical slider 9 via a bearing, providing stable support for the vertical slider 9. A locking nut is threadedly connected to the outer curved surface of the lower end of the vertical lead screw 10 to lock and tighten it after adjustment, preventing loosening during operation. A guide sleeve 901, made of polytetrafluoroethylene (PTFE), is embedded through the center of the vertical slider 9. The guide sleeve 901 has self-lubricating properties and its inner wall slides in conjunction with the horizontal slide rod 11. A guide slide rod 12 is welded to the inner side of the horizontal slide rod 11. The guide slide rod 12 is used to lift and unload the stamped car wheel hub 4. The guide slide rod 12 is designed as a downward-sloping triangular prism structure, its length matching the stroke height of the stamping seat 105. Its inner side is rounded to form a wedge shape, effectively preventing scratches on the edge of the car wheel hub 4. A support spring 13 is nested inside the vertical slider 9. The support spring 13 is a compressible spring, its side end abutting against the spring seat at the outer end of the guide slide rod 12. The support spring 13 provides continuous elastic support to the guide slide rod 12, ensuring its reset accuracy. An infrared positioning sensor 1201 is installed at the tail of the guide slide rod 12 by screws. The two sensors work together to achieve position calibration, ensuring that the two guide slide rods 12 always maintain a symmetrical state and improving the synchronization of the feeding action.

[0025] An adjusting seat 14 is mounted on the lower front side of the stamping base 105 via screws. An adjusting groove 15 is formed at the lower end of the adjusting seat 14. An adjusting screw 16 is rotatably connected to the middle of the adjusting groove 15 via a bearing. The adjusting screw 16 adopts a bidirectional trapezoidal thread design, with the threads at both ends rotating in opposite directions, enabling synchronous reverse movement of the adjusting sliders on both sides. Adjusting sliders 17 are connected to the outer curved surfaces of the adjusting screw 16 via threads on both sides. The adjusting sliders 17 slide against the inner wall of the adjusting groove 15. Guide bosses are provided on both sides of the sliders to prevent deflection during movement. A connecting rod 18 is rotatably connected to the lower end of the adjusting slider 17 via a pin. The outer side of the connecting rod 18 is rotatably connected to the adjusting rod 19 via a pin. The adjusting rod 19 and the adjusting shaft 5 are rigidly connected via a flat key. An adjusting motor 20 is mounted on the lower end of the stamping base 105 via a motor bracket. The adjusting motor 20 is a servo motor with precise speed adjustment and positioning functions. Its output shaft is connected to a first synchronous pulley 201 via a key. The outer end of the first synchronous pulley 201 is connected to a second synchronous pulley 202 via a synchronous belt drive. The second synchronous pulley 202 is connected to the outer end of the adjusting screw 16 via a key. Power transmission is achieved through synchronous belt drive, resulting in high transmission accuracy and smooth operation.

[0026] Furthermore, a limiting horizontal groove 801 is provided on the side end of the support platform 6. A horizontal lead screw 802 is rotatably connected to the middle of the horizontal groove 801 through a bearing. The horizontal lead screw 802 also adopts a trapezoidal thread structure, and a locking nut is connected to the outer curved thread for locking after adjustment. A horizontal slider 803 is connected to the outer curved thread in the middle of the horizontal lead screw 802. The horizontal slider 803 is slidably connected to the inner wall of the horizontal groove 801, and the horizontal groove 801 provides linear limiting for the horizontal slider 803. The extension frame 7 is fixedly installed at the bottom of the horizontal slider 803 by screws. By rotating the horizontal lead screw 802, the horizontal slider 803 can be moved, thereby adjusting the horizontal position of the extension frame 7.

[0027] To address the wear problem caused by long-term friction between the guide slide rod 12 and the horizontal slide rod 11, and to alleviate the impact stress during the downward movement of the car wheel hub 4, a polytetrafluoroethylene-ceramic composite lubricating coating is uniformly applied to the outer surfaces of both the guide slide rod 12 and the horizontal slide rod 11. This coating combines an extremely low coefficient of friction with excellent wear resistance, significantly reducing motion resistance and component wear, and extending the service life of the original structure. Simultaneously, a polyurethane elastic buffer pad (not shown in the figure) is adhered to the wedge-shaped surface inside the guide slide rod 12. This prevents hard contact between the guide slide rod 12 and the car wheel hub 4, preventing edge damage, and provides moderate damping during the downward movement of the car wheel hub 4, slowing down the downward speed. Combined with the buffer structure of the material collection device, this provides dual protection, effectively reducing the workpiece damage rate.

[0028] Please continue reading. Figures 1-6 This blanking module automatically completes the blanking action along with the up and down stroke of the stamping base 105, requiring no manual intervention throughout the entire process. It has a high degree of automation. The specific workflow is as follows: During the downward stamping stage: High-pressure oil is introduced into the hydraulic telescopic cylinder 104, driving the piston rod to extend and causing the stamping seat 105 to move smoothly downward along the column 102 and the vertical slide rod 106. The two triangular guide slide rods 12 integrated on the stamping seat 105 move downward simultaneously. At this time, the car wheel hub 4 blank has been accurately placed in the positioning groove of the lower die seat 3. As the guide slide rod 12 continues to move downward, its inner wedge-shaped end gradually approaches the upper edge of the car wheel hub 4. During the continued downward movement, the edge of the car wheel hub 4 generates a reverse resisting pressure on the wedge-shaped end of the guide slide rod 12, forcing the guide slide rod 12 to drive the horizontal slide rod 11 to slide outward along the inner wall of the guide sleeve 901. At the same time, the support spring 13 is compressed, allowing the spring to store elastic potential energy until the stamping seat 105 drives the upper die seat 2 and the lower die seat 3 to completely close, completing the stamping of the car wheel hub 4. During this process, the guide slide rod 12 retracts outward without interfering with the fitting accuracy of the upper mold base 2 and the lower mold base 3, ensuring that the forming dimensional tolerance of the car wheel hub 4 meets the requirements.

[0029] Spring ejection stage: After stamping is completed, the hydraulic telescopic cylinder 104 prepares to release pressure and reset, and the stamping seat 105 is about to move upward. At this time, the car wheel hub 4 has been formed and is attached to the surface of the lower mold base 3 due to stamping stress. The reverse resistance pressure on the guide slide rod 12 disappears. The support spring 13 releases the stored elastic potential energy, generating an inward thrust, which pushes the guide slide rod 12 to drive the horizontal slide rod 11 to extend inward along the inner wall of the guide sleeve 901 until the wedge-shaped end of the guide slide rod 12 tightly abuts against the lower edge of the formed car wheel hub 4. Under the limiting action of the horizontal slide rod 11 and the guide sleeve 901, the guide slide rod 12 remains in a stable extended position, preparing for the subsequent demolding action.

[0030] During the reset and demolding stage: the hydraulic telescopic cylinder 104 depressurizes, the piston rod retracts, driving the stamping seat 105 to reset upwards, and the guide slide rod 12 moves upwards linearly synchronously with the stamping seat 105. Since the wedge-shaped end of the guide slide rod 12 is pressed against the lower edge of the car wheel hub 4, the upward pulling force is evenly transmitted to the car wheel hub 4 through the guide slide rod 12, effectively overcoming the adhesion stress and vacuum suction force between the wheel hub and the lower mold base 3, driving the car wheel hub 4 to move upwards synchronously, achieving rapid demolding, and completely avoiding the problems of workpiece jamming and sticking.

[0031] Automatic sliding stage: As the stamping base 105 continues to rise, the guide slide rod 12 lifts the car wheel hub 4 until it is completely separated from the lower die base 3. Due to the downward tilt of the guide slide rod 12, the car wheel hub 4 slides smoothly downward along the wedge surface under its own weight and the guidance of the wedge-shaped surface of the guide slide rod 12, finally falling into the preset collection and conveying device, completing the entire unloading process. At this time, the stamping base 105 drives the upper die base 2 to reset to the initial position, and the support spring 13 returns to its initial state, waiting for the next stamping and unloading cycle.

[0032] This blanking module can be adapted to process different specifications of automobile wheel hubs 4 by adjusting the angle and position of the triangular guide slide 12, greatly improving the versatility of the equipment. The specific adjustment steps are as follows: First, adjust the height and horizontal position of the guide slide rod 12: Loosen the locking nut at the lower end of the vertical lead screw 10 and rotate the vertical lead screw 10. Since the vertical lead screw 10 is threadedly connected to the extension frame 7, the rotation generates an axial force, which drives the vertical slider 9 to move linearly up and down along the inner wall of the vertical slide groove 8. This, in turn, drives the guide slide rod 12 to adjust its height synchronously up and down through the guide sleeve 901 and the horizontal slide rod 11, with an adjustment accuracy of up to 0.05mm. At the same time, loosen the locking nut on the horizontal lead screw 802 and rotate the horizontal lead screw 802, driving the horizontal slider 803 to move horizontally along the inner wall of the horizontal slide groove 801. The horizontal slider 803 drives the extension frame 7 to move horizontally synchronously, which in turn drives the guide slide rod 12 to adjust its horizontal position through the vertical slider 9 and the horizontal slide rod 11. By combining the up and down adjustment and the horizontal adjustment, the height position and tilt angle of the guide slide rod 12 can be precisely adjusted to adapt to the needs of wheel hubs with different thicknesses and diameters.

[0033] Secondly, adjust the inner opening angle of the guide slide rod 12: Start the adjustment motor 20. The output shaft of the adjustment motor 20 drives the first synchronous pulley 201 to rotate. The first synchronous pulley 201 drives the second synchronous pulley 202 to rotate through the synchronous belt drive, which in turn drives the adjustment screw 16 to rotate synchronously. Since the two ends of the adjustment screw 16 have reverse threads, when rotating, the thread force will drive the two adjustment sliders 17 to move synchronously outward or inward along the inner wall of the adjustment groove 15. The adjustment sliders 17 drive the connecting rod 18 to move synchronously. The connecting rod 18 pulls or pushes the adjustment rod 19 through the pin, so that the adjustment rod 19 drives the adjustment shaft 5 to rotate relative to the bearing. When the adjustment shaft 5 rotates, the support platform 6 swings synchronously inward or outward through the flat key. The support platform 6 drives the extension frame 7, vertical slider, horizontal slide rod and guide slide rod 12 to swing as a whole, thereby adjusting the inner opening angle of the two guide slide rods 12, accurately adapting to the blanking of car wheel hubs 4 of different diameters, without the need to replace blanking parts, greatly reducing equipment adaptation costs and changeover time.

[0034] The beneficial effects of this invention are as follows: High structural integration and strong adaptability: This invention does not require additional drive device configuration, but is directly integrated into the stamping base 105. It achieves linkage feeding by relying on the up and down stroke of the stamping base 105, which simplifies the overall structure of the equipment, reduces manufacturing costs and later maintenance difficulty, and can be directly adapted to the transformation and upgrading of existing stamping equipment without the need to reconstruct the production line.

[0035] Stable material feeding and guaranteed workpiece quality: The triangular guide slide 12 and the car wheel hub 4 are in surface contact and the force is evenly distributed, which can effectively avoid the workpiece deformation and scratches caused by traditional top material structure. Combined with the smooth transition design of the wedge end and the elastic buffer pad, the quality of the wheel hub edge is further protected and the product qualification rate is improved.

[0036] High degree of automation and significantly improved production efficiency: The stamping and blanking processes are completed simultaneously without the need for manual intervention, greatly shortening the production cycle. At the same time, the guide slide parameters can be quickly adjusted through servo motors, bidirectional lead screws and other structures, reducing changeover time by more than 60% and making it compatible with the processing needs of different specifications of ring wheel hubs.

[0037] Low energy consumption and long service life: The material is unloaded by relying solely on the elastic potential energy of the support spring 13 and the gravity of the workpiece, without any additional energy consumption. Combined with the design of self-lubricating coating and wear-resistant guide sleeve, it reduces component wear, extends the service life of the module, and effectively reduces the energy consumption and operating costs of the production line.

[0038] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
