Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically a shaping device for automotive kerb parts. Background Technology

[0002] The forming device for automotive parts processing is a specialized piece of equipment designed for automotive parts that are prone to deformation after processing such as stamping, casting, and cutting. It achieves shape correction, dimensional finishing, and surface smoothing through mechanical pressure, hydraulic pressure, and other methods. Relying on high-precision positioning fixtures, adaptable tooling, and precise pressure, it eliminates residual stress from parts processing, corrects shape deviations such as bending and warping, and controls key dimensions within design tolerances, ensuring the assembly compatibility and product reliability of different types of parts such as shafts, thin-walled parts, and engine blocks.

[0003] Existing forming equipment for automotive parts processing typically uses a "machine tool to fix the workpiece + die stamping" model to achieve forming. However, this method is mostly for fixed-size adaptation of single parts and lacks multi-specification compatibility, which leads to a serious lack of production flexibility. When faced with market demands for multiple varieties and small batches, it is difficult to respond quickly. During the production changeover phase, not only is it necessary to replace the entire set of equipment or make complex tooling adjustments, but it also prolongs the production preparation cycle, reduces the overall production efficiency, and ultimately greatly increases the difficulty of production management and cost control pressure for enterprises. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing automotive parts shaping devices, which are mostly designed with fixed dimensions of "machine tool fixed workpiece + die stamping", and can only be adapted to a single model of parts, resulting in a lack of multi-specification compatibility and limited single shaping dimension. Moreover, existing devices are mostly single longitudinal stamping shaping, which easily leads to problems such as incomplete local correction and uneven distribution of shaping force. The invention provides an automotive kerb parts shaping device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shaping device for automotive kerf parts, comprising: a frame, an upper template fixedly connected to the top of the frame, a hydraulic cylinder mounted on the top of the upper template, the output end of the hydraulic cylinder extending through to the bottom of the upper template and fixedly connected to a stamping plate, and a lower mold mounted on the top of the frame; an adaptive locking mechanism, the adaptive locking mechanism being disposed at the bottom of the upper template for adapting to and locking workpieces of different specifications, the adaptive locking mechanism including multiple sets of second sleeves disposed at the bottom of the stamping plate, each set of second sleeves having multiple sleeves; and a transverse reciprocating movement mechanism, the transverse reciprocating movement mechanism being disposed at the bottom of the stamping plate for driving the second sleeves to reciprocate.

[0006] As a further embodiment of the present invention: the adaptive locking mechanism further includes a second connecting pipe fixedly connected to the bottom of the upper template, the input end of the second connecting pipe being fixedly connected to a first flexible tube, the top of the upper template being provided with a first connecting pipe, and the output end of the first connecting pipe being fixedly connected to the first flexible tube, the input end of the first flexible tube being equipped with a second solenoid valve, and a connector being provided on one side of the second connecting pipe.

[0007] As a further embodiment of the present invention: the connector includes a plurality of third hoses fixedly connected to the output end of the second connecting pipe, and the output ends of the plurality of third hoses are fixedly connected to the input ends of the plurality of second sleeves. A piston rod is slidably connected to the inner side of the second sleeve, and a shaping ball is installed on the inner side of the piston rod.

[0008] As a further embodiment of the present invention: the transverse reciprocating moving mechanism includes a plurality of second fixed seats fixedly connected to the bottom of the stamping plate, a sliding plate slidably connected to the inner side of each of the plurality of second fixed seats, and a plurality of sliding seats slidably connected to the inner side of each of the plurality of sliding plates.

[0009] As a further embodiment of the present invention: the reciprocating moving mechanism further includes a third connecting pipe fixedly connected to the bottom of the upper template, the input end of the third connecting pipe being fixedly connected to a second flexible hose, and the output end of the first connecting pipe being fixedly connected to the second flexible hose, the input end of the second flexible hose being equipped with a first solenoid valve, and a driver being provided on one side of the third connecting pipe.

[0010] As a further embodiment of the present invention: the driver includes a plurality of first sleeves slidably connected to the bottom of the stamping plate, a piston plate slidably connected to the inner side of each of the plurality of first sleeves, a connecting post fixedly connected to one side of the piston plate, and the connecting post fixedly connected to the sliding plate, a plurality of fourth hoses fixedly connected to the output end of the third connecting pipe, and the output ends of the plurality of fourth hoses fixedly connected to the input end of one of the first sleeves, and an oscillator is provided on the top of the sliding seat.

[0011] As a further embodiment of the present invention: the oscillator includes a drive rod fixedly connected to the top of the sliding seat, the top of the stamping plate is provided with a plurality of wave grooves, and the wave grooves are configured to be wave-shaped, the drive rod is sleeved inside the wave grooves, and the bottom of the sliding seat is provided with an avoidance component.

[0012] As a further embodiment of the present invention: the avoidance component includes a first fixed seat fixedly connected to the bottom of the sliding seat, a ball rotatably connected to the inner side of the first fixed seat, a rectangular block fixedly connected to the bottom of the ball, the bottom of the rectangular block being fixedly connected to the top of the second sleeve, and four arc-shaped springs installed between the bottom of the first fixed seat and the outer wall of the rectangular block.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting an adaptive locking mechanism, the piston rod is driven to move the shaping ball downward, so that multiple sets of piston rods are locked after conforming to the contour of the standard workpiece. It can adapt to workpieces of different shapes, sizes and minor differences without changing the mold or adjusting the structure. This reduces the cost of special tooling, avoids manual positioning deviation, improves production flexibility and efficiency, and reduces the difficulty and cost pressure of enterprise production management. 2. By setting up a transverse reciprocating movement mechanism, the first solenoid valve is adjusted to drive the shaping ball to move laterally and reciprocate and reset cyclically. This breaks the limitation of single longitudinal shaping, corrects the minor deformation of the workpiece and reduces the deviation through repeated rolling and shaping, and makes the shaping force more balanced and expands the coverage area, avoiding damage to the workpiece surface and making it compatible with workpieces with high surface precision requirements. 3. By setting up an oscillator, the shaping ball moves back and forth, driving the drive rod to move obliquely along the wave groove, forming a multi-dimensional shaping trajectory. This not only expands the shaping coverage area and corrects minor deformations of the workpiece layer by layer to reduce deviations, but also disperses contact points and avoids force concentration. Combined with rolling friction, it reduces the risk of workpiece surface damage. 4. By setting up an obstacle avoidance component, when the shaping ball contacts the edge of the workpiece, the piston rod can swing flexibly around the ball and return to its original position by an arc spring after disengagement. This not only avoids damage to the edge of the workpiece and is suitable for fragile types of workpieces, but also buffers the impact, reduces component wear, and extends the service life of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0018] Please see Figures 1-10 This embodiment provides a shaping device for automotive kerf parts, including: a frame 1, an upper template 2 fixedly connected to the top of the frame 1, a hydraulic cylinder 3 mounted on the top of the upper template 2, the output end of the hydraulic cylinder 3 extending through to the bottom of the upper template 2 and fixedly connected to a stamping plate 4, and a lower mold 5 mounted on the top of the frame 1; an adaptive locking mechanism, the adaptive locking mechanism being disposed at the bottom of the upper template 2, used to adapt to and lock workpieces of different specifications, the adaptive locking mechanism including multiple sets of second sleeves 19 disposed at the bottom of the stamping plate 4, each set of second sleeves 19 having multiple sleeves; the adaptive locking mechanism also includes parts fixedly connected to the upper template 2. The bottom has a second connecting pipe 8, the input end of which is fixedly connected to a first flexible hose 7. The top of the upper template 2 is provided with a first connecting pipe 6, and the output end of the first connecting pipe 6 is fixedly connected to the first flexible hose 7. The input end of the first flexible hose 7 is equipped with a second solenoid valve 12. A connector is provided on one side of the second connecting pipe 8. The connector includes multiple third flexible hoses 13 fixedly connected to the output end of the second connecting pipe 8, and the output ends of the multiple third flexible hoses 13 are all fixedly connected to the input ends of multiple second sleeves 19. A piston rod 20 is slidably connected to the inner side of the second sleeve 19, and a shaping ball 30 is installed on the inner side of the piston rod 20. Both the second solenoid valve 12 and the hydraulic cylinder 3 are controlled by a PLC controller, which can realize the switching regulation of the second solenoid valve 12 and the intermittent start of the hydraulic cylinder 3. When the worker needs to shape workpiece 17, firstly, the first connecting pipe 6 is connected to the external hydraulic pipeline (the external hydraulic pipeline is connected by a hydraulic pump, and the PLC controller can control the opening and closing of the hydraulic pump). Then, the standard workpiece 17 is placed in the shaping station at the top of the lower mold 5. Subsequently, the PLC controller pressurizes the hydraulic pump, causing the hydraulic oil in the first connecting pipe 6 to be injected into the second sleeve 19 and fill it. Immediately afterwards, the PLC controller drives the hydraulic cylinder 3 to move, causing the stamping plate 4 to move downward, which in turn pushes the shaping ball 30 downward through the piston rod 20. When the bottom of the shaping ball 30 contacts the standard workpiece 17, different parts of the standard workpiece 17 will sequentially abut against the piston rod 20, keeping the piston rod 20 stationary. Finally, multiple piston rods 20 completely conform to the contour of the standard workpiece 17. At this time, some hydraulic oil in the second sleeve 19 corresponding to the piston rod that contacts the workpiece will flow back. The PLC controller then commands the hydraulic cylinder 3 to stop moving and simultaneously closes the second solenoid valve 12, causing the piston rod 20 to... In the locked state, this design allows multiple piston rods 20 to be automatically positioned and locked by conforming to the contour of the standard workpiece 17, without the need to change special molds or adjust the mechanical structure. It can adapt to workpieces of different shapes and sizes, and can also cope with minor dimensional differences in similar workpieces. This effectively reduces the procurement and storage costs of special tooling. At the same time, after the piston rods are tightly fitted and locked to the standard workpiece, the forming process is directly based on the standard contour, avoiding manual positioning deviations and greatly improving production flexibility. This allows the equipment to quickly respond to the market demand for multiple varieties and small batches, thereby significantly improving overall production efficiency and ultimately reducing the difficulty of production management and cost control pressure for enterprises. After the position of the piston rod 20 is adjusted, the standard workpiece 17 is removed, and the workpiece 17 to be shaped is placed in the shaping position at the top of the mold 5. At this time, the PLC controller controls the hydraulic cylinder 3 to start, and the output end of the hydraulic cylinder 3 drives multiple sets of shaping balls 30 to move downward. At this time, multiple sets of shaping balls 30 contact various parts of the workpiece 17 at the same time, thereby performing shaping operation on the workpiece 17, thus improving the shaping effect of the workpiece 17. When the shaping ball 30 shapes the workpiece 17, it can roll along the surface of the workpiece 17, significantly reducing the friction with the workpiece 17, allowing it to smoothly roll along the contour of the workpiece 17. At the same time, the gentle rolling contact can avoid squeezing friction on the surface of the workpiece 17, thereby reducing the residual stress inside the workpiece 17, reducing the risk of deformation and cracking after shaping, and effectively improving the structural stability of the finished product.

[0019] Please see Figures 2 to 10A transverse reciprocating movement mechanism is located at the bottom of the stamping plate 4 and is used to drive the second sleeve 19 to reciprocate. The transverse reciprocating movement mechanism includes multiple second fixed seats 27 fixedly connected to the bottom of the stamping plate 4. A sliding plate 18 is slidably connected to the inner side of each of the multiple second fixed seats 27, and multiple sliding seats 22 are slidably connected to the inner side of each of the multiple sliding plates 18. The reciprocating movement mechanism also includes a third connecting pipe 10 fixedly connected to the bottom of the upper template 2. A second flexible hose 9 is fixedly connected to the input end of the third connecting pipe 10, and the output end of the first connecting pipe 6 is fixedly connected to the second flexible hose 9. A first solenoid valve 11 is installed at the input end of the second flexible hose 9, and a driver is provided on one side of the third connecting pipe 10. The driver includes multiple first sleeves 15 slidably connected to the bottom of the stamping plate 4. A piston plate 14 is slidably connected to the inner side of each of the multiple first sleeves 15, and a connecting valve 11 is fixedly connected to one side of the piston plate 14. A column 21 is fixedly connected to a sliding plate 18. The output end of the third connecting pipe 10 is fixedly connected to multiple fourth hoses 16, and the output ends of the multiple fourth hoses 16 are all fixedly connected to the input end of a first sleeve 15. A swing device is provided on the top of the sliding seat 22. The swing device includes a drive rod 28 fixedly connected to the top of the sliding seat 22. Multiple wave grooves 29 are opened on the top of the stamping plate 4, and the wave grooves 29 are wave-shaped. The drive rod 28 is sleeved on the inner side of the wave grooves 29. An avoidance component is provided at the bottom of the sliding seat 22. The avoidance component includes a first fixed seat 24 fixedly connected to the bottom of the sliding seat 22. A ball 23 is rotatably connected to the inner side of the first fixed seat 24. A rectangular block 25 is fixedly connected to the bottom of the ball 23. The bottom of the rectangular block 25 is fixedly connected to the top of the second sleeve 19. Four arc-shaped springs 26 are installed between the bottom of the first fixed seat 24 and the outer wall of the rectangular block 25. The first solenoid valve 11 is controlled by a PLC controller, enabling precise on / off control. When multiple sets of shaping balls 30 synchronously contact various parts of the workpiece 17 and initiate the shaping operation, the PLC controller instructs the first solenoid valve 11 to open. External hydraulic oil is injected into the inner side of multiple first sleeves 15 through the second hose 9, driving the sliding plate 18 to move laterally, thereby causing the shaping balls 30 to move laterally synchronously, realizing the reciprocating operation of the shaping balls 30 during the shaping process. When the shaping balls 30 move to a set distance, the external hydraulic pipe will draw in the inner side of the first sleeve 15, causing the internal hydraulic oil to flow back, driving the shaping balls 30... The process of resetting and reversing is repeated to complete the back-and-forth shaping of workpiece 17. In this design, the lateral reciprocating movement of the shaping ball 30 breaks the limitation of single longitudinal shaping. The multiple back-and-forth rolling shaping is equivalent to "repeated rolling and shaping", which can gradually correct the minor deformation of workpiece 17, avoid the incomplete local correction caused by single shaping, and further reduce the deviation between the finished product and the standard contour. At the same time, the combination of lateral movement and rolling friction makes the shaping force borne by each part of workpiece 17 more balanced, which not only expands the force coverage, but also prevents damage to the workpiece surface due to local concentrated force, and is compatible with workpiece 17 with high surface precision requirements. As the shaping ball 30 moves back and forth, it synchronously drives the drive rod 28 to move. Under the guidance of the wave groove 29, the drive rod 28 moves back and forth along the groove trajectory, thereby driving the shaping ball 30 to move obliquely, further expanding the shaping coverage area of ​​the workpiece 17. This multi-dimensional back and forth movement is equivalent to "all-round repeated shaping", which can correct the minor bumps and deformations on the surface of the workpiece 17 layer by layer, avoiding the problem of inadequate local correction caused by single-direction shaping, and further reducing the deviation between the finished product and the standard contour. At the same time, the oblique movement makes the contact points between the shaping ball 30 and the workpiece 17 more dispersed and more flexible, which can effectively avoid the concentration of force in local areas. Combined with the rolling friction advantage of the shaping ball 30, it can further reduce the risk of surface damage to the workpiece 17. When the shaping ball 30 contacts the edge of the workpiece 17 during its back-and-forth movement, the piston rod 20 can swing flexibly around the ball 23 under the resistance of the workpiece 17. When the shaping ball 30 loses contact with the edge of the workpiece 17, the piston rod 20 automatically resets under the elastic force of the arc spring 26. This flexible swinging design replaces the traditional rigid contact, effectively avoiding the shaping ball 30 from applying concentrated squeezing force to the edge of the workpiece 17, thereby preventing damage such as chipping, deformation, and scratches on the edge of the workpiece 17. It is particularly suitable for workpieces with fragile edges, sharp corners, or brittle materials. At the same time, the elastic reset mechanism of the arc spring 26 can buffer the contact impact force between the shaping ball 30 and the edge of the workpiece 17, reduce the rigid impact on core components such as the piston rod 20 and the drive rod 28, reduce the wear rate of components, and thus extend the overall service life of the equipment.
