Description

Technical Field

[0001] This invention relates to the field of automotive parts stamping technology, and more specifically, to an automotive parts stamping forming equipment. Background Technology

[0002] Automotive tubing stamping equipment is specifically designed for stamping automotive tubing. Its working principle is based on the stamping process, which uses stamping dies and a stamping press to apply pressure to metal sheets or tubing, causing plastic deformation to obtain tubing of the desired shape and size. Aluminum alloy, as a lightweight, high-strength, and corrosion-resistant metal material, is widely used in automotive tubing manufacturing to achieve weight reduction. Stamping can be classified into separation processes (blanking) and forming processes. Forming processes specifically include bending, stretching, bulging, flanging, and shaping.

[0003] Existing technologies for bending and stamping long aluminum alloy tubular parts (such as torsion beams and anti-collision beams) in automobiles have multiple drawbacks: Long aluminum alloy tubular parts lack precise helical feeding and self-adaptive clamping, requiring workers to manually push them into the bending seat. The tendency of shaft-tube parts to roll leads to low manual positioning efficiency, large random errors in feeding, and misalignment of the tubular part's axis with the bending rollers, resulting in inaccurate bending positions and quality control issues. Traditional manual feeding frequency is only about 10-15 times per minute. Furthermore, there is no automatic transfer system between multiple stamping steps, requiring workers to lift extra-long tubular parts to the sub-machine mold, which not only poses significant safety hazards... In addition to the risk of fatigue-induced misjudgment accidents, repeated clamping leads to loss of reference, causing secondary misalignment, local stress concentration, fracture of thin-walled aluminum alloy tubes, and reduced yield. Existing aluminum alloy tubes often lack internal mandrel support during bending, resulting in large springback during free bending and easy flattening of the cross-section. Manual pressure cannot be applied synchronously for shaping, leading to out-of-tolerance forming dimensions. At the same time, manual feeding lacks any central support, and the cantilevered droop of ultra-long tubes further amplifies feeding sway and bending misalignment. The difficulty in positioning aluminum tubes is a pain point that existing production lines urgently need to improve. These common problems in aluminum alloy stamping have also been confirmed by industry summaries. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a stamping and forming equipment for automotive parts. In addition to stamping automotive aluminum alloy parts, the present invention also constructs a fully automated system from active feeding, adaptive guidance, internal support bending to robotic gripper transfer, and can adapt to parts of different sizes.

[0005] To solve the above problems, the present invention adopts the following technical solution: An automotive parts stamping forming equipment includes: a stamping mechanism and a feeding mechanism.

[0006] In a preferred embodiment of the present invention, a first electric push rod for longitudinal adjustment is fixedly connected to the surface of the stamping seat, and the piston rod of the first electric push rod is fixedly connected to the stamping plate.

[0007] In a preferred embodiment of the present invention, a first slide block is slidably connected to the surface of the stamping base, a guide wheel is rotatably connected to the surface of the first slide block, and a guide plate adapted to the guide wheel is slidably connected to the surface of the first slide block.

[0008] As a preferred embodiment of the present invention, a second electric push rod for adjusting the guide plate is fixedly connected to the surface of the first slide, and a third electric push rod for adjusting the first slide is fixedly connected to the surface of the stamping seat.

[0009] In a preferred embodiment of the present invention, a first servo motor is fixedly connected to the surface of the second slide block, and the output shaft of the first servo motor is fixedly connected to the turntable. A fourth electric push rod for adjusting the second slide block is fixedly connected to the surface of the stamping frame. A displacement sensor for positioning the inner support column is fixedly connected to the surface of the second slide block. A blocking plate is horizontally slidably connected to the outer surface of the stamping frame. A fifth electric push rod for adjusting the blocking plate is fixedly connected to the surface of the stamping frame.

[0010] As a preferred embodiment of the present invention, a threaded rod is rotatably connected to the surface of the feeding rack, and a third slide is threadedly connected to the surface of the threaded rod. A second servo motor is fixedly connected to the surface of the feeding rack, and the output shaft of the second servo motor is fixedly connected to the threaded rod.

[0011] In a preferred embodiment of the present invention, a first electric cylinder is fixedly connected to the surface of the third slide block, and the piston rod of the first electric cylinder is fixedly connected to the top block.

[0012] In a preferred embodiment of the present invention, a rotating component is rotatably connected to the surface of the conveying seat, and an adjusting cylinder adapted to the rotating cylinder is rotatably connected to the surface of the rotating component. An electric gripper is fixedly connected to the inside of one outer end of the adjusting cylinder, and a second electric cylinder for adjusting the rotating component is rotatably connected to the surface of the conveying seat.

[0013] As a preferred embodiment of the present invention, a third servo motor is fixedly connected to the surface of the conveyor seat, and synchronous pulleys are fixedly connected to both the surface of the output shaft of the third servo motor and the surface of the rotating cylinder, and the two synchronous pulleys are connected by a synchronous belt drive.

[0014] In a preferred embodiment of the present invention, a pallet is rotatably connected to the surface of the conveyor seat, a roller is rotatably connected to the surface of the pallet, and a third electric cylinder for adjusting the pallet is rotatably connected to the surface of the conveyor seat.

[0015] Compared with the prior art, the advantages of this invention are: This invention utilizes a precision helical feed mechanism employing a second servo motor and a threaded rod, combined with a first electric cylinder and a two-stage pusher block, to eliminate random errors from manual feeding. The first slide and guide plate on the stamping base dynamically adapt to the pipe diameter under the drive of the second and third electric push rods, ensuring the axis of the long aluminum alloy tube is always aligned with the bending roller. The inner support column under the stamping frame is indexed by the first servo motor and positioned in a closed-loop manner by a displacement sensor, providing rigid support from inside the aluminum alloy tube cavity during bending. This transforms the springback and flattening defects of traditional free bending into high-precision shaping. Simultaneously, a blocking plate and support rollers assist in limiting and supporting the workpiece, allowing even ultra-long aluminum alloy beams to be processed stably. The entire equipment requires no manual intervention for workpiece movement; the electric grippers and rotating cylinder facilitate inter-process transfer, avoiding manual handling. The safety hazards and debris splashing cleaning difficulties of traditional core-bending equipment require a separate core-pulling mechanism to repeatedly insert and extract the pipe. Moreover, bending and stamping are done on different machines, resulting in the accumulation of repeated positioning errors between processes. In contrast, this application fixes the internal support column at the bottom of the turntable and also serves as the indexing reference. When it comes into contact with the first bending roller, the second bending roller, and the longitudinal sliding stamping plate at the same station, it realizes the combined action of internal support, circumferential indexing, and external bending and stamping in one go. This structure makes the aluminum alloy thin-walled tube suppress collapse during bending due to full internal support, and the pressing down of the stamping plate directly offsets the springback of the aluminum alloy. Compared with the independent use of known servo feeding and gripper transfer equipment, this solution eliminates the form and position tolerance chain of multi-machine transfer within the same stamping frame, which is not obvious. This invention replaces most of the hard mold adjustments with electric push rods, servo motors, and pneumatic components. The second, third, and fourth slides are all repositioned through parametric control, allowing the same production line to switch between producing aluminum alloy torsion beams, anti-collision beams, or seat frame tubing within half an hour. The synchronous belt drive and adjustable pallet of the conveyor seat adapt to different cross-sections and lengths, and the modular design of the internal support columns allows for quick interchangeability to adapt to different hole diameters. This structure not only reduces mold storage and downtime losses, but also cleverly transforms bending, a standard stamping process, into a combined action of internal support bending, reducing the number of processes. Although existing tube bending systems can store parameters for hundreds of product models to achieve flexible production changeover, their bending, laser cutting, or tube end processing still require multiple machines to be connected. Instead of using external calculations to compensate for deformation, this application uses internal displacement sensors and multi-stage slide parameterization to create a closed-loop system for feeding, guiding, internal support indexing, bending and stamping, and gripper rotation. This eliminates the need for external devices such as straightening and flaring, as required by omnidirectional pipe bending machines, enabling the processing of ultra-long aluminum alloy beams. The modular interchangeability of the internal support columns and the full constraint formed by the rollers supporting the ultra-long pipes break through the limitations of conventional pipe bending machines on pipe length. This allows a single machine to switch between multiple products within half an hour while maintaining high repeatability and positioning accuracy. This subtractive high integration achieved by integrating known bending machines, mandrels, feeding, and grippers in a specific time sequence and space constitutes a technical effect that is not easily conceived by those skilled in the art.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0019] Please see Figure 1-8 An automotive parts stamping forming equipment includes: a stamping mechanism 1 and a feeding mechanism 2. The stamping mechanism 1 includes a stamping seat 101, a bending seat 102 fixedly connected to the surface of the stamping seat 101, two first bending rollers 103 rotatably connected longitudinally to the surface of the bending seat 102, a second bending roller 104 adapted to the first bending rollers 103 rotatably connected laterally to the surface of the bending seat 102, a stamping plate 105 adapted to the first bending rollers 103 slidably connected longitudinally to the surface of the stamping seat 101, a stamping frame 112 fixedly connected to the surface of the stamping seat 101, a second slide 113 slidably connected longitudinally to the surface of the stamping frame 112, a turntable 114 rotatably connected to the bottom of the second slide 113, and a plurality of inner support columns 115 adapted to the first bending rollers 103 fixedly connected to the bottom of the turntable 114. The feeding mechanism 2 includes a feeding frame 201 fixedly connected to one side of the stamping seat 101. A third slide 202 is horizontally slidably connected to the surface of the feeding frame 201. A top block 203 is horizontally slidably connected to the surface of the third slide 202. A fourth slide 207 is fixedly connected to the surface of the feeding frame 201 and located between the third slide 202 and the first slide 107. A conveying seat 208 is fixedly connected to the surface of the fourth slide 207. A rotating cylinder 209 is rotatably connected inside the conveying seat 208.

[0020] Specifically, the third slide 202 on the feeding frame 201 of the feeding mechanism 2 slides horizontally, driving the top block 203 to push aluminum alloy automotive parts, such as long tubular aluminum alloy workpieces, to the stamping seat 101. The two first bending rollers 103, longitudinally rotatably connected to the surface of the bending seat 102, and the second bending roller 104, laterally rotatably connected, work together with the stamping plate 105, which slides longitudinally on the surface of the stamping seat 101, to bend and stamp the workpiece. Simultaneously, the second slide 113 on the stamping frame 112 descends, causing the bottom of the turntable 114 to... The support column 115 is inserted into the aluminum alloy tube to provide support and prevent deformation. The displacement sensor 118 ensures positioning accuracy. It integrates feeding, bending, internal support and stamping, and solves the problem of low efficiency in traditional single stamping. The multi-roller bending and the internal support column 115 improve the forming quality of complex tubular aluminum alloy automotive parts, reduce manual intervention, and improve production consistency and safety. It is suitable for mass production of long shaft parts such as aluminum alloy tubes for car door hinges and aluminum alloy torsion beams. It also has the advantages of compact structure and flexible adjustment, which significantly enhances the versatility of the equipment.

[0021] Furthermore, a first electric push rod 106 for longitudinal adjustment is fixedly connected to the surface of the stamping base 101, and the piston rod of the first electric push rod 106 is fixedly connected to the stamping plate 105.

[0022] Specifically, after receiving a signal from the control system, the first electric push rod 106 extends and retracts, directly driving the stamping plate 105 to slide longitudinally along the surface of the stamping seat 101. This dynamically adjusts the positive pressure of the stamping plate 105 on the workpiece placed between the first bending roller 103 and the second bending roller 104, adapting to the bending and stamping requirements of aluminum alloy automotive parts with different wall thicknesses or materials. When the turntable 114 drives the inner support column 115 to support the aluminum alloy tube, pressure can be applied simultaneously to ensure the shape accuracy. The precise and controllable thrust adjustment of the first electric push rod 106 replaces the traditional fixed mold gap, greatly improving the flexibility of the equipment. It can quickly switch to produce aluminum alloy door anti-collision beams or aluminum alloy chassis tube beams of different specifications without replacing a large number of molds, reducing downtime. Moreover, the stable pressure feedback avoids overpressure rupture or underpressure deformation, improving product consistency and mold life, and reducing the company's equipment investment costs.

[0023] Please see Figure 3The surface of the stamping base 101 is slidably connected to a first slide block 107, the surface of the first slide block 107 is rotatably connected to a guide wheel 108, and the surface of the first slide block 107 is slidably connected to a guide plate 109 adapted to the guide wheel 108.

[0024] Specifically, when the feeding mechanism 2 sends the workpiece to the stamping area, the first slide 107 can move horizontally along the stamping seat 101 to approach or move away from the bending seat 102. The workpiece passes between the guide wheel 108 and the guide plate 109. The guide wheel 108 rotates to reduce friction, and the guide plate 109 restricts lateral offset, so that the axis of the aluminum alloy long tube is aligned with the first bending roller 103 and the second bending roller 104. This provides a reliable guide for automotive parts such as aluminum alloy long tubular beams to enter the stamping station, overcoming the defect that the aluminum alloy tube is prone to swaying when fed in, resulting in inaccurate bending position. The sliding first slide 107 adapts to the end support of aluminum alloy workpieces of different lengths, and with the subsequent inner support column 115, it forms end limit, which greatly improves the repeatability of stamping and bending, reduces scrap, and improves the automation continuity of the production line.

[0025] Please see Figure 4 A second electric push rod 110 for adjusting the guide plate 109 is fixedly connected to the surface of the first slide 107, and a third electric push rod 111 for adjusting the first slide 107 is fixedly connected to the surface of the stamping seat 101.

[0026] Specifically, the second electric push rod 110 pushes the guide plate 109 to slide laterally relative to the guide wheel 108 to clamp aluminum alloy workpieces of different diameters. The third electric push rod 111 drives the entire first slide block 107 to adjust the horizontal displacement of the guide reference. The two work together to achieve automatic pre-adjustment of the width of the feeding channel. The equipment can change the guide spacing and position with one click according to the workpiece model parameters stored in the PLC, eliminating the need for manual wrench adjustment. It is suitable for the production of multiple varieties of small batch automotive pipe parts, and can also accommodate aluminum alloy seat slide rails and aluminum alloy steering knuckle sleeves. The closed-loop control of the second electric push rod 110 and the third electric push rod 111 ensures that the clamping force is moderate and does not damage the surface, improving versatility and changeover efficiency, and reducing debugging time and skill dependence.

[0027] Please see Figure 5 A first servo motor 116 is fixedly connected to the surface of the second slide block 113, and the output shaft of the first servo motor 116 is fixedly connected to the turntable 114. A fourth electric push rod 117 for adjusting the second slide block 113 is fixedly connected to the surface of the stamping frame 112. A displacement sensor 118 for positioning the inner support column 115 is fixedly connected to the surface of the second slide block 113. A baffle plate 119 is horizontally slidably connected to the outer surface of the stamping frame 112. A fifth electric push rod 120 for adjusting the baffle plate 119 is fixedly connected to the surface of the stamping frame 112.

[0028] Specifically, the fourth electric push rod 117 lowers the second slide block 113 to insert the inner support column 115 into the tube. The first servo motor 116 rotates the tube to the required bending angle position via the turntable 114. The displacement sensor 118 provides real-time feedback on the insertion depth and indexing position of the inner support column 115. The blocking plate 119 extends from the fifth electric push rod 120 to block the end face of the workpiece and prevent axial movement. This achieves digital control of the internal support and circumferential indexing bending of the tube. Compared with the traditional free bending without inner support, which has a large springback, the aluminum alloy A-pillar or B-pillar high-strength tube formed by this solution has stable dimensions. In addition, the blocking plate 119 protects against the impact of the stamping plate 105, significantly improving overall safety and yield, and meeting the stringent tolerances of automotive safety structural components.

[0029] Please see Figure 6 The surface of the feeder 201 is rotatably connected to a threaded rod 205, and the third slide 202 is threadedly connected to the surface of the threaded rod 205. The surface of the feeder 201 is fixedly connected to a second servo motor 206, and the output shaft of the second servo motor 206 is fixedly connected to the threaded rod 205.

[0030] Specifically, the second servo motor 206 drives the threaded rod 205 to rotate according to the set pulse, converting the rotary motion into high-precision linear displacement of the third slide 202 along the feed frame 201, thereby carrying the top block 203 to push the workpiece to the stamping station at a uniform speed or pull it back, realizing intermittent feeding synchronized with the stamping rhythm. The second servo motor 206 has high positioning accuracy, making the step length of long tubes programmable to adapt to the spacing of multiple bending stations, reducing cumulative errors.

[0031] Furthermore, a first electric cylinder 204 is fixedly connected to the surface of the third slide block 202, and the piston rod of the first electric cylinder 204 is fixedly connected to the top block 203.

[0032] Specifically, when the third slide 202 reaches the material picking position, the first electric cylinder 204 extends its piston rod, causing the top block 203 to abut against the end of the workpiece and push it from the material rack to the inlet of the guide wheel 108, or push out the waste material in the opposite direction after stamping. Clean pneumatics replaces manual lifting, avoiding the hazards of metal dust. Moreover, the stroke of the top block 203 is controllable and will not damage the surface coating of the parts. It forms a two-stage coarse and fine propulsion with the threaded rod 205 feeding. First, the first electric cylinder 204 quickly approaches and then the servo precisely sets the distance, taking into account both efficiency and accuracy. It is particularly suitable for lightweight feeding of aluminum alloy tubes for new energy battery trays, reducing the risk of workplace injuries and speeding up the process. It expands the automation level of the equipment, reduces the number of operators, and realizes unmanned units.

[0033] Please see Figure 7A rotating component 210 is rotatably connected to the surface of the conveyor seat 208. An adjusting cylinder 211 adapted to the rotating cylinder 209 is rotatably connected to the surface of the rotating component 210. An electric gripper 212 is fixedly connected to the inside of one outer end of the adjusting cylinder 211. A second electric cylinder 216 for adjusting the rotating component 210 is rotatably connected to the surface of the conveyor seat 208.

[0034] Specifically, the third servo motor 213 drives the rotating drum 209 to rotate and transport the workpiece via the synchronous pulley 214 and synchronous belt 215. At the same time, the second electric cylinder 216 pushes the rotating part 210 to swing, causing the electric gripper 212 at the end of the adjusting cylinder 211 to open and grip or release the tube, completing the inter-process transfer. The swingable electric gripper 212 realizes the automatic gripping and reversing of workpieces before and after stamping, overcoming the safety hazards of manually moving stamped parts to the next mold in the existing solution. Moreover, the electric gripper 212 adapts to different diameters and works with the rotating drum 209 to continuously transport the workpiece, making the production line smooth, greatly reducing the accumulation and collision of work-in-process, and improving the level of intelligence in the automotive parts stamping workshop.

[0035] Please see Figure 8 A third servo motor 213 is fixedly connected to the surface of the conveyor seat 208. The surface of the output shaft of the third servo motor 213 and the surface of the rotating cylinder 209 are both fixedly connected to synchronous pulleys 214, and the two synchronous pulleys 214 are connected by a synchronous belt 215.

[0036] Specifically, the power output of the third servo motor 213 is transmitted to the rotating drum 209 via the synchronous pulley 214 and synchronous belt 215 with low noise, driving the aluminum alloy automotive long tube placed on it to rotate smoothly for feeding or follow-up bending, ensuring consistent linear speed. The synchronous belt 215 transmission eliminates gear backlash, matching the speed of the conveying and stamping inner support column 115, avoiding surface scratches on the aluminum alloy tube. Furthermore, the servo adjustable speed can achieve constant speed or variable speed curves, adapting to different process rhythms, improving equipment compatibility, reducing maintenance costs, ensuring the cycle stability during mass production of car door beams, and ensuring that the equipment complies with the definition of metal stamping manufacturing because bending itself is a bending process in the stamping forming process.

[0037] Furthermore, a pallet 219 is rotatably connected to the surface of the conveyor seat 208, a roller 217 is rotatably connected to the surface of the pallet 219, and a third electric cylinder 218 for adjusting the pallet 219 is rotatably connected to the surface of the conveyor seat 208.

[0038] Specifically, the extension and retraction of the third electric cylinder 218 causes the pallet 219 to rotate around the hinge point, changing the support height of the roller 217. This supports the middle of long tubes with different outer diameters to prevent deflection during feeding. The rotating roller 217 reduces resistance and provides auxiliary support for ultra-long aluminum alloy tubular beams in automotive parts. It solves the bending and misalignment caused by the drooping of the cantilever feeding. In particular, it forms full constraint with the inner support column 115, enabling high-precision forming of long aluminum alloy tubes. Moreover, the passive rotation of the roller 217 does not scratch the surface, improving the processing limit and product range of the equipment, and providing convenience for enterprises to undertake more aluminum alloy parts for various car models.
