Description

Technical Field

[0001] This invention relates to the field of metal forming, and more specifically to an adjustable forging device for processing automotive parts. Background Technology

[0002] Forging is a core process in automotive parts forming, primarily used for the precision forging of shafts, discs, and round blanks. It demands high standards for workpiece consistency, dimensional accuracy, and surface quality. Currently, conventional forging equipment on the market has relatively limited functionality and still suffers from numerous practical shortcomings in actual production.

[0003] Currently, most forging equipment relies on manual placement and alignment of metal billets before operation. The accuracy of manual alignment is greatly affected by the operator's experience, easily leading to billet misalignment. This results in forging eccentricity, uneven workpiece wall thickness, and a high scrap rate. Furthermore, automotive forging billets with different outer diameters require different positioning fixtures. Traditional positioning structures are mostly fixed and cannot adaptively adjust the spacing. During production changes, the entire fixture needs to be disassembled and reassembled, resulting in poor adaptability and failing to meet the flexible production needs of diverse, small-batch automotive parts.

[0004] In addition, forged workpieces are prone to adhesion to the mold cavity. Traditional equipment lacks a dedicated mechanical demolding structure and mostly relies on manual knocking and prying for demolding. This not only results in low work efficiency and high labor intensity, but manual operation is also prone to workpiece deformation and mold damage, posing certain safety hazards. Existing forging equipment with auxiliary demolding functions mostly requires independent electrical control, induction switches, and auxiliary drive mechanisms to achieve sequential actions. The equipment structure is complex and costly. Furthermore, the forging workshop is characterized by harsh vibration and dust conditions, leading to a high failure rate of electrical structures, difficult maintenance, and insufficient equipment operational stability.

[0005] Meanwhile, the positioning, forging, and demolding processes of existing forging equipment are independent of each other, and the process connection relies on manual operation. The degree of automation is low, the overall production cycle is limited, and it is difficult to adapt to large-scale automotive parts forging production.

[0006] Therefore, there is a need to provide an adjustable forging device based on automotive parts processing, which aims to solve the above problems. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an adjustable forging device based on the processing of automotive parts.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an adjustable forging press based on automotive parts processing, comprising a forging press and a forging die, wherein the forging die is mounted on the forging press, and a drive assembly, a centering assembly and a switching assembly are symmetrically arranged on both sides of the forging press; The drive assembly includes a placement frame, which is disposed on both sides of the forging press. A limit slider is slidably connected to the top of the placement frame. A rectangular groove block is fixedly connected to the top of the limit slider. A trapezoidal lifting block is slidably connected inside the rectangular groove block. The centering component includes a first connecting plate, which is rotatably connected to the outer wall of a rectangular groove block. A limiting slide rod is slidably connected inside the first connecting plate. A T-shaped groove block is fixedly connected to the end of the limiting slide rod away from the first connecting plate. An abutment slider is symmetrically slidably connected inside the T-shaped groove block.

[0009] Preferably, the drive assembly includes a grooved plate assembly, which is fixedly connected to the outer wall of the trapezoidal lifting block. The bottom of the placement frame is symmetrically fixedly connected to a connecting frame assembly, and the top of each connecting frame assembly is rotatably connected to a drive disk and a gear disk.

[0010] Preferably, the drive assembly includes a track, which is connected between the drive disc and the gear disc, and a rack and pinion assembly is symmetrically fixedly connected to the forging press.

[0011] Preferably, the centering component includes a bidirectional threaded rod, which is rotatably connected inside the T-shaped groove block, and anti-slip torques are symmetrically fixed at both ends of the bidirectional threaded rod.

[0012] Preferably, a plurality of first reset springs are provided at equal intervals between the first connecting plate and the T-shaped groove block, with one end of each of the plurality of first reset springs fixedly connected to the first connecting plate and the other end of each of the plurality of first reset springs away from the first connecting plate fixedly connected to the T-shaped groove block.

[0013] Preferably, the switching component includes a second connecting plate, which is fixedly connected to the side of the rectangular groove block away from the first connecting plate. A pressing block is slidably connected inside the second connecting plate, and a connecting rod assembly is fixedly connected to the side of the pressing block near the second connecting plate.

[0014] Preferably, the switching assembly includes a second reset spring, which is sleeved on the outside of the connecting rod assembly and disposed between the second connecting plate and the pressing block.

[0015] Preferably, the switching assembly includes a J-shaped rotating rod, which is rotatably connected to the side of the pressing block near the second connecting plate. A limiting groove plate is fixedly connected inside the second connecting plate, and the end of the J-shaped rotating rod away from the pressing block is slidably connected inside the limiting groove plate.

[0016] Preferably, the gear disk is disposed on the motion path of the rack and pinion assembly, and the rack and pinion assembly meshes with the gear disk.

[0017] Preferably, the end of the connecting rod assembly away from the pressing block is fixedly connected to the trapezoidal lifting block, and trigger plates are symmetrically arranged on both sides of the forging press, and the trigger plates are arranged on the movement path of the pressing block.

[0018] The adjustable forging device for automotive parts processing provided by this invention has the following advantages compared with the prior art: By using a rack and pinion assembly, gear disc, and track in conjunction with the guide groove curve of the grooved plate assembly, the timing of positioning, forging, and demolding is rigidly defined, achieving automated connection of the three processes. No manual step-by-step operation or electrical timing control is required, making it suitable for complex working conditions in forging workshops and effectively improving overall production cycle time and operational efficiency.

[0019] By setting up an automatic centering and positioning structure, the forging slide block can automatically drive the two side contact slide blocks to approach the billet and complete the centering calibration during the downward movement, eliminating the need for manual alignment. At the same time, it works in conjunction with the first return spring to achieve flexible contact positioning, which can not only ensure the alignment accuracy of the billet and reduce the workpiece scrap problem caused by eccentric forging, but also avoid rigid extrusion scratching the surface of the high-temperature billet, effectively improving the workpiece forming quality and production qualification rate.

[0020] By setting up a purely mechanical timing switching component and a trapezoidal lifting block demolding structure, the working mode can be automatically switched based on the lifting cycle of the forging press. During the return stroke of the forging forming, the trapezoidal lifting block can be automatically extended. The horizontal displacement of the wedge structure generates a vertical component force to smoothly pry the workpiece adhering to the mold cavity, replacing the traditional manual demolding method, reducing the intensity of manual labor, avoiding workpiece deformation, mold collision and safety hazards caused by manual operation, and improving the stability and safety of demolding operation.

[0021] The distance between the two-way threaded rod and the anti-slip torque can be symmetrically adjusted by adjusting the distance between the two sides of the sliding block. It can adapt to round, disc and shaft automotive forging blanks with different outer diameters. Production changeover can be completed without changing the positioning tooling, which effectively improves the equipment's versatility and flexible production capacity, and reduces tooling changeover costs and changeover time.

[0022] This solution features a high degree of overall integration and is easy to modify. It can be directly adapted to conventional automotive parts forging equipment without requiring significant changes to the original equipment structure. The modification cost is low, and the solution is highly adaptable. It can balance production efficiency and equipment operation stability while ensuring forging precision and product quality, and has good practical application value. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0026] In the description of this invention, the terms “center,” “horizontal,” “up,” “down,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 3 As shown, an adjustable forging device for processing automotive parts provided by an embodiment of the present invention includes a forging press 11 and a forging die 12. The forging die 12 is mounted on the forging press 11. A drive assembly, a centering assembly, and a switching assembly are symmetrically arranged on both sides of the forging press 11. The three sets of components cooperate with each other to realize automated sequential actions.

[0029] Driver component structure like Figures 4 to 6 As shown, the drive assembly includes a placement frame 21, a limiting slider 22, a rectangular groove block 23, a trapezoidal lifting block 24, a grooved plate assembly 25, a connecting frame assembly 26, a drive disc 27, a gear disc 28, a track 29, and a rack and pinion assembly 210. The placement frame 21 is located on both sides of the forging press 11. The limiting slider 22 is slidably connected to the top of the placement frame 21, and a rectangular groove block 23 is fixedly connected to the top of the limiting slider 22. The trapezoidal lifting block 24 is slidably connected inside the rectangular groove block 23. The grooved plate assembly 25 is fixedly connected to the outer wall of the trapezoidal lifting block 24. Connecting frame assemblies 26 are symmetrically fixedly connected to the bottom of the placement frame 21. Each connecting frame assembly 26 has a drive disc 27 and a gear disc 28 rotatably connected to its top. The track 29 is connected between the drive disc 27 and the gear disc 28. The rack and pinion assembly 210 is symmetrically fixedly connected on the forging press 11. The gear disc 28 is set on the movement path of the rack and pinion assembly 210, and the rack and pinion assembly 210 meshes with the gear disc 28.

[0030] The drive assembly is the core of the power timing of the entire device. The rack and pinion assembly 210 moves up and down synchronously with the slider of the forging press 11, drives the gear disk 28 to rotate through meshing, and then drives the drive disk 27 to rotate synchronously via the track 29. An integrated protrusion is set on the outer side of the track 29. The protrusion is slidably assembled inside the closed guide groove of the groove plate assembly 25. The reciprocating movement timing of the rectangular groove block 23 and the trapezoidal lifting block 24 is controlled by the trajectory curve of the closed guide groove, realizing the rigid timing switch of different actions in the two stages of forging downward and return upward. The action rhythm can be completely synchronized with the forging operation without electrical control.

[0031] Centered component structure like Figure 9 and Figure 10 As shown, the central component includes a first connecting plate 31, a limiting slide bar 32, a T-shaped groove block 33, an abutting slider 34, a bidirectional threaded rod 35, an anti-slip twister 36, and a first return spring 37. The first connecting plate 31 is rotatably connected to the outer wall of the rectangular groove block 23. The limiting slide bar 32 is slidably connected inside the first connecting plate 31. The end of the limiting slide bar 32 away from the first connecting plate 31 is fixedly connected to the T-shaped groove block 33. The abutting slider 34 is symmetrically slidably connected inside the T-shaped groove block 33. The bidirectional threaded rod 35 is rotatably connected inside the T-shaped groove block 33. The two ends of the bidirectional threaded rod 35 are symmetrically fixedly connected to the anti-slip twister 36. A plurality of first return springs 37 are equidistantly distributed between the first connecting plate 31 and the T-shaped groove block 33. One end of each first return spring 37 is fixedly connected to the first connecting plate 31, and the end of each first return spring 37 away from the first connecting plate 31 is fixedly connected to the T-shaped groove block 33.

[0032] The centering component is the core structure for automatic blank centering and specification self-adaptation. Manually rotating the anti-slip torque 36 drives the bidirectional threaded rod 35 to rotate. The bidirectional threaded rod 35 drives the two opposing sliding blocks 34 to slide synchronously towards or away from each other, precisely adjusting the distance between the two opposing sliding blocks 34. This adapts to metal blanks of automotive parts with different outer diameters, offering strong versatility. During operation, the two opposing sliding blocks 34 symmetrically conform to the outer wall of the blank. The first return spring 37 provides flexible buffering to prevent rigid contact from scratching the surface of the high-temperature blank. At the same time, elastic expansion and contraction eliminate over-positioning interference, ensuring alignment accuracy. The first connecting plate 31 can switch its flipping posture with the abutment of the trapezoidal lifting block 24, realizing the switching between the storage and unfolding states of the positioning structure, adapting to different spatial requirements of positioning and demolding operations.

[0033] Switching component structure like Figure 7 and Figure 8 , Figure 11As shown, the switching assembly includes a second connecting plate 41, a pressing block 42, a connecting rod assembly 43, a second return spring 44, a J-shaped rotating rod 45, a limiting groove plate 46, and a trigger plate 47. The second connecting plate 41 is fixedly connected to the side of the rectangular groove block 23 away from the first connecting plate 31. The pressing block 42 is slidably connected inside the second connecting plate 41, and the connecting rod assembly 43 is fixedly connected to the side of the pressing block 42 near the second connecting plate 41. The second return spring 44 is sleeved on the outside of the connecting rod assembly 43 and is positioned between the second connecting plate 41 and the pressing block 42. The J-shaped rotating rod 45 is rotatably connected to the side of the pressing block 42 near the second connecting plate 41. The limiting groove plate 46 is fixedly connected inside the second connecting plate 41, and the end of the J-shaped rotating rod 45 away from the pressing block 42 is slidably connected within the limiting groove plate 46. The end of the connecting rod assembly 43 away from the pressing block 42 is fixedly connected to the trapezoidal lifting block 24. The forging press 11 is symmetrically provided with trigger plates 47 on both sides, and the trigger plates 47 are located on the movement path of the pressing block 42.

[0034] The switching component is a purely mechanical state switching core. It relies on the contact and separation of the pressing block 42 and the trigger plate 47, combined with the energy storage and release of the second reset spring 44, to control the J-shaped rotating rod 45 to slide and lock within the limiting slot plate 46. This, in turn, uses the connecting rod group 43 to pull the trapezoidal lifting block 24 to complete the extension and retraction state switching. This structure can automatically retract the lifting structure and switch to the billet centering positioning mode during the forging downward phase, and automatically extend the lifting structure and switch to the demolding and scraping mode during the forging return phase. The entire process requires no manual intervention, relying on mechanical stroke to automatically complete the working mode switching. It has a stable structure, strong anti-interference ability, and is suitable for high-temperature and high-vibration forging conditions.

[0035] In the initial state of forging operation, the slider of the forging press 11 and the rack and pinion assembly 210 are at the upper dead point, the rectangular groove block 23 is located at the outer limit position of the placement frame 21, the pressing block 42 and the trigger plate 47 abut against the compression of the second reset spring 44, the J-shaped rotating rod 45 is locked into the limit groove plate 46, and the trapezoidal lifting block 24 extends out and abuts against the first connecting plate 31, so that the central component maintains a vertical unfolding posture.

[0036] When the slide of the forging press 11 descends for forging, the rack and pinion assembly 210 engages with the drive gear disk 28 and drive disk 27 to rotate. Through the cooperation of the track 29 and the groove plate assembly 25, the rectangular groove block 23 is moved towards the center of the equipment. The two sides of the sliding block 34 simultaneously move closer together, flexibly pushing the metal billet to be centered and positioned. During the inward movement of the rectangular groove block 23, the pressing block 42 disengages from the trigger plate 47, the second reset spring 44 extends and unlocks, the trapezoidal lifting block 24 retracts, and the centering component flips and flattens to avoid the forging space. When the slide descends to the bottom dead center to complete the forging, the mechanism simultaneously resets and relocks, completing the mode switch.

[0037] After forging is completed, the slide rises and returns, and the rack and pinion assembly 210 engages in reverse, driving the rectangular groove block 23 to reciprocate again. The pressing block 42 disengages from the trigger plate 47 again, and the trapezoidal lifting block 24 extends outward and lifts the central component to make room for material removal. The wedge-shaped end of the trapezoidal lifting block 24 inserts into the gap between the workpiece and the mold, generating a vertical component force through horizontal displacement to pry the formed workpiece away from the mold, achieving purely mechanical demolding. The end-of-stroke mechanism is fully reset, awaiting the next forging cycle.

[0038] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments: Initial working state Before the forging operation begins, the slider and rack and pinion assembly 210 of the forging press 11 are at the top dead center position, and the rectangular groove block 23 is located at the outer limit position of the placement frame 21 away from the center of the forging press 11. At this time, the pressing block 42 and the trigger plate 47 abut against each other and are squeezed and retracted into the second connecting plate 41, and the second return spring 44 is in a compressed and stored state. The front end of the J-shaped rotating rod 45 is inserted into the locking track recess of the limiting groove plate 46, and the connecting rod assembly 43 pushes the trapezoidal lifting block 24 to extend to the outside of the rectangular groove block 23; the trapezoidal lifting block 24 abuts against the first connecting plate 31, causing the first connecting plate 31 to rotate around the rectangular groove block 23 to a vertical position, and driving the limiting slide bar 32, the T-shaped groove block 33, and the two abutting sliders 34 symmetrically arranged inside the T-shaped groove block 33 to maintain a position perpendicular to the rectangular groove block 23.

[0039] Descent stroke: billet centered positioning The slide of the forging press 11 descends, driving the forging die 12 to descend and perform the forging operation. The rack and pinion assembly 210 descends synchronously with the slide and meshes with the gear disk 28 rotatably mounted on the connecting frame assembly 26, driving the gear disk 28 to rotate. The gear disk 28 transmits power to the drive disk 27 through the track 29, causing the drive disk 27 to rotate synchronously. A protrusion is fixed on the outer side of the track 29, and the protrusion is movably assembled in the closed guide groove of the groove plate assembly 25. In the initial stage of the drive disk 27 starting to rotate, the protrusion slides along the feed section of the guide groove, and pushes the rectangular groove block 23, the limiting slide block 22, and the trapezoidal lifting block 24 mounted on the rectangular groove block 23 through the groove plate assembly 25, so that they move together along the top guide rail of the placement frame 21 towards the center of the forging press 11.

[0040] As the rectangular groove block 23 moves, the first connecting plate 31 drives the limiting slide bar 32, the T-shaped groove block 33, and the contact slider 34 to move towards the metal billet on the forging die 12. The contact sliders 34 on both sides symmetrically contact the outer circumference of the billet. With the help of the elastic compression buffer of the first return spring 37 and the application of a flexible pushing force, the billet is gradually pushed to the center of the die, completing the automatic centering calibration. The centering driving force is entirely taken from the downward power of the slider of the forging press 11, without the need for an additional power source. The positioning action is precisely synchronized with the forging cycle.

[0041] As the rectangular groove block 23 moves inward, the pressing block 42 disengages from the trigger plate 47, and the second return spring 44 extends elastically, pushing the pressing block 42 and the connecting rod assembly 43 to move away from the second connecting plate 41. Simultaneously, the pressing block 42 drives the J-shaped rotating rod 45 to disengage from the limiting groove plate 46, and the trapezoidal lifting block 24 retracts into the rectangular groove block 23, releasing its constraint on the first connecting plate 31. The first connecting plate 31 rotates around the rectangular groove block 23, causing the limiting slide rod 32, the T-shaped groove block 33, and the two symmetrically arranged abutment sliders 34 inside it to adopt an attitude parallel to the rectangular groove block 23.

[0042] Descent endpoint: Working mode switch As the drive disc 27 continues to rotate, the drive rectangular groove block 23 resets outward along the placement frame 21. At the end of the reset stroke, the pressing block 42 re-engages with the trigger plate 47, and the trigger plate 47 pushes the pressing block 42 back into the second connecting plate 41. This action is transmitted through the connecting rod assembly 43, causing the trapezoidal lifting block 24 to tend to extend outward; at the same time, the J-shaped rotating rod 45 slides along the guide surface of the limiting groove plate 46 under the action of thrust, and slides back into the locking track recess, achieving the mechanism switching state. The forging press 11 slide reaches the bottom dead center, the forging die 12 closes, and the billet forging is completed.

[0043] Lifting stroke: Assists in demolding and material removal After forging is completed, the slide block of the forging press 11 drives the forging die 12 to rise during the return stroke. The rack and pinion assembly 210 rises synchronously and meshes with the gear disk 28 in the opposite direction, driving the gear disk 28 and the drive disk 27 to rotate in the opposite direction. The drive disk 27 then relies on the track 29 to cooperate with the groove plate assembly 25, driving the rectangular groove block 23 to perform a second reciprocating motion.

[0044] After the pressing block 42 disengages from the trigger plate 47, the second reset spring 44 elastically resets and pushes the pressing block 42 outward. This drives the trapezoidal lifting block 24 to extend outward from inside the rectangular groove block 23 via the connecting rod assembly 43. During the extension of the trapezoidal lifting block 24, the actuating structure on its sidewall abuts against the first connecting plate 31, forcing the first connecting plate 31 to flip upward to be perpendicular to the rectangular groove block 23. This causes the T-shaped groove block 33 and the abutting slider 34 to flip and rise, creating operating space for the material removal operation. As the rectangular groove block 23 continues to move inward, the wedge-shaped guide surface at the front end of the extended trapezoidal lifting block 24 inserts into the gap between the bottom of the molded workpiece and the mold surface. The horizontal feed generates an upward component force to lift the workpiece, weakening the adhesive friction between the workpiece and the mold cavity, thus separating the workpiece from the mold and completing the purely mechanically assisted demolding.

[0045] Ascent endpoint: Mode reset After the trapezoidal lifting block 24 completes the material shoveling operation, the drive disc 27 continues to rotate and enters the reset stage, pulling the rectangular groove block 23 to return to its original position. At the end of the return stroke, the pressing block 42 again contacts the trigger plate 47 and is pressed into the second connecting plate 41; the front end of the J-shaped rotating rod 45 is once again embedded in the locking track recess of the limiting groove plate 46, and the connecting rod assembly 43 again abuts against the first connecting plate 31 with the help of the trapezoidal lifting block 24. The first connecting plate 31 rotates around the rectangular groove block 23 to a vertical position, causing the limiting slide bar 32, the T-shaped groove block 33, and the two symmetrically arranged abutting sliders 34 inside it to return to their initial position perpendicular to the rectangular groove block 23.

[0046] Adaptability and regulatory effects For automotive part blanks of different diameters, the device is equipped with a manual adjustment structure. The rotating anti-slip torque 36 drives the bidirectional threaded rod 35 to rotate, symmetrically adjusting the distance between the two contact sliders 34 to quickly adapt to changes in the blank's outer diameter and ensure centering positioning accuracy. The first return spring 37 acts as a buffer during the centering positioning stage, preventing the contact sliders 34 from scratching the blank surface; it also allows the limiting slide rod 32 to have a sliding compensation amount relative to the first connecting plate 31, eliminating over-positioning interference during mechanism operation.

[0047] The timing of the entire device's drive, centering, and material-shoveling actions is determined by the number of meshing teeth between the rack and pinion assembly 210 and the gear disk 28, as well as the rigidity of the guide groove curve of the groove plate assembly 25. Through the aforementioned purely mechanical linkage structure, the three processes of "centering positioning - forging forming - assisted demolding" are automatically connected, effectively improving the operational safety and production efficiency of automotive parts forging production.
