Description

Technical Field

[0001] This invention relates to the field of stamping part forming technology, specifically a rapid forming device for stamping parts. Background Technology

[0002] In the landscape of modern manufacturing, sheet metal stamping technology has become a key process for the mass production of core components due to its high efficiency and low cost. U-shaped structural components, as a fundamental load-bearing and connecting unit, are ubiquitous in automobile body frames, home appliance frames, and the internal structures of various precision machinery. However, after the plastic deformation process of stamping or bending, sheet metal inevitably experiences a "springback" phenomenon due to stress release, causing deviations in the workpiece's sidewall angles, opening dimensions, and critical fillet radii from the design blueprint. To ensure that these U-shaped components meet the stringent dimensional tolerances and geometric accuracy requirements of subsequent assembly, they must undergo subsequent shaping and surface finishing. This has become an indispensable key step in improving the quality of the final product. This step is not merely a simple dimensional correction, but a process of redistributing and stabilizing the internal stress of the material, directly affecting the product's fatigue strength, collision safety performance, and overall reliability. This has become an indispensable key step in improving the quality of the final product.

[0003] In current production practices, the shaping and grinding of U-shaped stamping parts are usually carried out separately. The shaping process generally employs automated equipment such as specialized hydraulic or servo presses, which can efficiently correct the macroscopic deformation of the workpiece. However, the subsequent grinding, deburring, or side finishing processes still largely rely on manual operation. Workers manually process the workpiece with hand-held grinding tools. This "machine shaping, manual grinding" model is not only labor-intensive and inefficient, but the grinding quality is also highly susceptible to the influence of the worker's skill level and fatigue, leading to poor product consistency and posing certain safety hazards. Therefore, a rapid shaping device for stamping parts is needed to address these shortcomings. Summary of the Invention

[0004] Technical problems to be solved While the current "machine shaping and manual polishing" model can correct macroscopic deformation, the subsequent manual polishing process is labor-intensive, inefficient, and results in poor product quality consistency. It is significantly affected by human factors and poses safety hazards, making it difficult to meet the modern manufacturing industry's demand for efficient and high-precision production.

[0005] Technical solution To achieve the above objectives, the present invention provides the following technical solution: a rapid forming device for stamped parts, comprising: Support frame; A support base is fixed to the bottom of the support frame and has a concave surface for accommodating the arc segment of the U-shaped piece. The control element is movably disposed within the support frame; Two pairs of molding parts are movably mounted on the support frame and are connected to the control component for driving the parts to move closer or further apart under the drive of the control component, so as to shape the vertical part of the U-shaped part. A shaping component is connected to the control component and moves toward or away from the support base with the control component to cooperate with the support base to shape the arc segment of the U-shaped component; A pair of grinding components, respectively disposed on both sides of the support base, are used to grind the sides of the U-shaped part; and A linkage component is connected between the control component and the grinding assembly, and is used to drive the grinding assembly to switch to the working position during the movement of the control component.

[0006] Furthermore, the control element includes: A pair of hydraulic cylinders are both fixed to the top of the support frame; Mounting plate, the top of which is fixedly connected to the telescopic end of the hydraulic cylinder; and Two pairs of wedges are fixed to the bottom of the mounting plate, and the inclined surfaces of each pair of wedges are arranged opposite each other.

[0007] Furthermore, the molded part includes: A molding plate, used to contact the vertical part of the U-shaped component; The slider is fixed to the top of the molding plate and slidably connected to the support frame; The guide wheel is movably connected to the top of the slider via a rotating shaft and makes rolling contact with the inclined surface of the wedge. When the wedge moves downward, it pushes the two sliders closer together through the guide wheel.

[0008] Furthermore, a guide frame is fixed on the support frame, and symmetrical guide grooves are provided on the inner side of the guide frame. The slider is slidably disposed in the guide grooves. A folding spring is fixedly disposed between the slider and the end wall of the guide groove.

[0009] Furthermore, the shaping component includes: A connecting strip, the top end of which is fixed to the bottom of the mounting plate; and The shaping plate is arc-shaped and fits the arc segment of the U-shaped piece. Its top is fixedly connected to the bottom of the connecting strip.

[0010] Furthermore, the polishing component includes: The guide frame has a U-shaped hollow structure; A sliding frame is slidably connected to the guide frame; The grinding disc is movably connected to the sliding frame via a rotating shaft; A toothed rail, fixed to the outside of the guide frame; and Gear 1 is movably connected to the sliding frame via a rotating shaft and meshes with the gear rail, used to drive the sliding frame to move along the arc-shaped path of the guide frame.

[0011] Furthermore, the polishing assembly also includes: Servo motor one, fixed on the sliding frame, is used to drive the grinding disc to rotate; and Servo motor 2 is fixed on the sliding frame and is used to drive gear 1 to rotate.

[0012] Furthermore, the linkage component includes: A pair of rotating rods are rotatably connected within the support frame and fixedly connected to the guide frame of the corresponding grinding assembly; and A pair of synchronizing elements are disposed on both sides inside the support frame and are connected to the control element and the rotary rod for transmission. When the control element descends, it drives the rotary rod to rotate, thereby rotating the guide frame from the standby position to the working position.

[0013] Furthermore, the synchronization element includes: Double-sided racks are slidably connected to the inner side of the support frame; A pair of gears are movably connected to the inner side of the support frame via a rotating shaft and mesh with the corresponding sides of the double-sided rack; A pair of synchronizing pulleys are fixed to the shaft of the gear. A pair of synchronized pulleys are respectively fixed to the rotating rod; and A timing belt is wrapped around the outside of the timing pulleys 1 and 2 on the same side to achieve synchronous rotation of the gear 2 and the rotating rod.

[0014] Furthermore, the synchronization element also includes: The connecting rod is L-shaped, with its top end fixedly connected to the mounting plate of the control component and its bottom end fixedly connected to the top end of the double-sided rack, so that the mounting plate and the double-sided rack move vertically synchronously.

[0015] Compared with the prior art, this rapid forming device for stamped parts has the following advantages: I. This invention integrates the three major processes of molding, shaping, and polishing into a single set of equipment, which is uniformly driven by a hydraulic cylinder in the control unit. It utilizes precision mechanical structures such as wedges and linkages to achieve synchronous or sequential execution of multiple actions, simplifying the production process and shortening the processing cycle of a single stamped part, thereby achieving a significant improvement in production efficiency.

[0016] Second, this invention provides powerful and stable molding and shaping force by using a hydraulic cylinder in conjunction with a wedge block mechanism, and achieves closed-loop control by using pressure sensors and displacement sensors. This allows for precise control of the pressure and stroke applied to the workpiece, ensuring that springback deformation is completely eliminated, and achieving high standard of shape accuracy for the arc and vertical sections, thus significantly improving the final quality of the product.

[0017] Third, by setting up a linkage consisting of a rotary rod, double-sided racks, synchronous pulleys, synchronous belts and connecting rods, the present invention enables the attitude switching of the grinding component (from standby to working position) to be completely synchronized with the downward movement of the main drive cylinder. No additional drive unit and control steps are required, achieving seamless connection between processes and demonstrating a high level of automation and intelligence. Attached Figure Description

[0020] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-8 As shown, the present invention provides a technical solution: a rapid forming device for stamped parts. The entire device is based on a heavy-duty welded support frame 1. The frame is welded from thick-walled rectangular steel pipes or industrial structural steel (such as Q235) and undergoes stress-relief annealing treatment to prevent deformation after long-term use. The bottom of the support frame 1 is equipped with adjustable height shock-absorbing feet to maintain the level and stability of the equipment on uneven ground.

[0022] At the bottom center of the support frame 1, a tool steel support base 2 that has been quenched is fixed with high-strength bolts. On the upper surface of the support base 2, a concave surface is milled with a high-precision five-axis machining center. The concave surface has a radius of curvature that is exactly the same as the bottom arc segment of the target U-shaped part (the tolerance is controlled within ±0.02mm). The surface of the concave surface is polished and has several tiny ventilation holes. It is connected to a negative pressure system. When the workpiece is placed, the negative pressure can be activated to use suction to initially fix the workpiece in the concave surface and prevent displacement during the subsequent molding process.

[0023] The top of the support frame 1 is a sturdy mounting platform on which a pair of synchronous hydraulic cylinders 301 are symmetrically mounted via flanges. To ensure synchronization, it is recommended to use a hydraulic synchronous motor or an electro-hydraulic servo system for control. The cylinder diameter and stroke of the hydraulic cylinder 301 are precisely calculated and selected based on the workpiece's plasticity and forming depth. Its working pressure is adjustable and equipped with a pressure sensor for real-time feedback.

[0024] At the upper part of the support frame 1, a guide frame 8 made of aerospace-grade aluminum alloy (such as 7075 aluminum alloy) is fixed by positioning pins and bolts. Aluminum alloy is chosen to reduce the inertia of moving parts. Inside the guide frame 8, there are two hardened steel guide rail strips to form a high-precision guide groove.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the slider 402 is made of wear-resistant bronze or alloy steel and forms a sliding fit with the guide rail insert with a small gap (about 0.01-0.02mm). A pre-compressed strong folding spring 9 is installed between the outer end of each slider 402 and the end wall of the guide groove. The preload of the spring is precisely calculated to ensure that the slider 402 is reliably in the open position when not in operation, and to prevent the wedge block 303 from bearing too much resistance in the initial stage of downward movement.

[0026] The guide wheel 403 mounted on the top of the slider 402 is made of high carbon chromium bearing steel (such as GCr15) and is precision ground to achieve a surface hardness of HRC60 or higher. The guide wheel 403 is connected to the slider 402 through a high-precision needle roller bearing to ensure that the frictional resistance is minimized when it rolls on the inclined surface of the wedge block 303. The molding plate 401 is fixed to the bottom of the slider 402 in a detachable manner (such as dovetail groove + bolts) to facilitate quick replacement according to different workpieces. The working surface of the molding plate 401 can be glued with polyurethane elastomer to prevent scratching the workpiece surface during extrusion.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the mounting plate 302 is made of thick steel plate to ensure sufficient rigidity and prevent bending under stress. The two pairs of wedges 303 at its bottom also need to be subjected to high-frequency quenching and grinding to ensure long-term stable contact with the guide wheel 403. The shaping plate 502 itself is made of the same tool steel material as the support seat 2. Its arc curvature forms a pair of precise "yin and yang molds" with the concave surface of the support seat 2. The fitting gap can be set according to the thickness of the workpiece material, usually 5%-10% of the material thickness, to achieve over-correction.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the guide frame 601 of the grinding assembly 6 is made of lightweight and high-strength titanium alloy or aluminum alloy to reduce the rotational inertia of the rotating rod 701. Its internal U-shaped track groove ensures that the sliding frame 602 moves smoothly without jamming. The sliding frame 602 is an integrated functional module. The "servo motor 1 606" installed on it is a high-speed spindle motor with a speed of thousands to tens of thousands of revolutions per minute. It is connected to grinding wheels or polishing heads of different grit sizes through a chuck. The "servo motor 2 607" provides precise positioning and low-speed, high-torque output. It drives gear 1 605 through a harmonic reducer or planetary reducer to ensure that the grinding disc 603 can move smoothly along the U-shaped side at an extremely low speed to achieve fine grinding. Both servo motors are connected to the electrical control cabinet at the rear of the equipment through a cable chain. Their start, stop, speed and movement trajectory are programmed and controlled by an independent motion controller (such as a PLC or motion control card).

[0029] The linkage mechanism is the core of realizing the intelligence of this device. The vertical and horizontal rods of the L-shaped connecting rod 707 are reinforced with reinforcing ribs to improve its bending resistance. The sliding fit between the double-sided rack 702 and the support frame 1 is equipped with a linear slide groove to ensure smooth movement. The gear 2 703 and the synchronous pulley 1 704 are connected to the same rotating shaft by splines to ensure no relative slippage. The synchronous belt 706 adopts a high-precision, low-elongation synchronous toothed belt and is equipped with a tension adjustment device to ensure no transmission delay and no error. The connection between the rotating rod 701 and the support frame 1 adopts a preloaded tapered roller bearing to eliminate radial and axial clearance and ensure the rigidity and accuracy of the guide frame 601 when it is flipped.

[0030] Working principle: I. Preparation and Material Loading Stage The operator first selects a processing program that matches the U-shaped part to be processed via the human-machine interface. After the program starts, the system activates the negative pressure system connected to the concave surface inside the support base 2. The operator places the U-shaped part with its opening facing upwards into the concave surface of the support base 2. The negative pressure immediately and firmly adheres to the workpiece, completing the initial fixation. At this time, the photoelectric sensor installed on the equipment detects that the workpiece is correctly positioned, and the system indicator light turns green, indicating that the equipment is ready and can be started.

[0031] II. Startup and Synchronous Execution Phase When the operator presses the start button, the PLC controller issues a command, and the two hydraulic cylinders 301 in the control unit 3 extend synchronously, pushing the mounting plate 302 to descend slowly and smoothly, and then turning to descend rapidly, driving the entire actuator to start working.

[0032] III. Shaping and Reshaping Stage As the mounting plate 302 descends, the inclined surfaces of the four wedges 303 fixed to its bottom begin to contact the guide wheels 403 at the top of the slider 402 in the molded part 4. Driven by the inclined surfaces of the wedges 303, the sliders 402 on both sides slide horizontally towards the center along the guide grooves within the guide frame 8 fixed to the upper part of the support frame 1, simultaneously stretching the folding springs 9 between the sliders 402 and the end walls of the guide grooves. The movement of the sliders 402 causes the bottom molded plates 401 to move closer together until they clamp the vertical sections on both sides of the U-shaped part. Displacement sensors mounted on the sliders 402 monitor the movement distance in real time. When the preset position is reached, the PLC controls the hydraulic cylinder 301 to slow down, and the system switches to pressure control mode, applying a set holding pressure to the side walls.

[0033] At the same time, the downward movement of the mounting plate 302 also pushes the shaping plate 502 vertically downward through the connecting strip 501 in the shaping component 5. The shaping plate 502 and the concave surface of the support base 2 form a pair of precise "yin and yang molds" to pressurize and shape the arc segment of the U-shaped part. The pressure sensor of the hydraulic system ensures that the set shaping tonnage is reached, so as to achieve precise correction of the arc segment.

[0034] IV. Grinding Station Linkage Switching Phase During the entire downward movement of the hydraulic cylinder 301, the linkage 7 works synchronously. The L-shaped connecting rod 707, fixed to the side of the mounting plate 302, moves downward and pulls the double-sided rack 702 to slide vertically in the groove inside the support frame 1. The linear motion of the double-sided rack 702 drives the two gears 703 meshing with it to rotate synchronously. The shaft of the gear 703 drives the synchronous wheel 704 fixed on it to rotate. The power is transmitted to the synchronous wheel 705 on the same side through the synchronous belt 706. The synchronous wheel 705 drives the rotating rod 701 to rotate, thereby causing the guide frame 601 of the grinding assembly 6, which is fixedly connected to the rotating rod 701, to flip upward from the horizontal standby position. The angle encoder installed on the rotating rod 701 provides real-time feedback on the flip angle. When the 90° vertical working position is reached, the encoder sends a signal, and an electromagnetic brake immediately locks the rotating rod 701 to prevent the guide frame 601 from shaking during subsequent grinding.

[0035] V. Precision Grinding Execution Stage After receiving the signal that the guide frame 601 has arrived, the PLC starts the grinding program. The servo motor 606 in the grinding assembly 6 starts and drives the grinding disc 603 to rotate at a preset speed through the chuck. At the same time, the servo motor 607 starts and drives the gear 605 to rotate through the reducer. The gear 605 meshes with the toothed rail 604 fixed on the outside of the guide frame 601, thereby driving the entire sliding frame 602 to carry the grinding disc 603 along the U-shaped path of the guide frame 601 to perform one or more reciprocating grindings on the side of the U-shaped part. The pressure during the grinding process can be controlled by constant force through the floating mechanism or the current feedback of the servo motor 606.

[0036] VI. Reset and Cycling Phase After the grinding process is completed, all servo motors stop. The PLC-controlled hydraulic cylinder 301 drives the mounting plate 302 and all connected components to move upwards quickly. During the reset process, the wedge block 303 disengages from the guide wheel 403. Under the restoring force of the folding spring 9, the slider 402 of the molded part 4 slides outwards along the guide groove of the guide frame 8, returning to the open position. At the same time, the connecting rod 707 pushes the double-sided rack 702 upwards. Through the reverse transmission of the linkage 7, the rotating rod 701 rotates in the opposite direction, causing the guide frame 601 to flip to the horizontal standby position. The negative pressure system is released, and the operator can then remove the processed workpiece. At this point, the entire device returns to its initial standby state, ready for the next work cycle.
