Description

Technical Field

[0001] This invention relates to the field of flanging mold technology, specifically to a flanging and side forming structure and method for adjacent positions of an automotive mold. Background Technology

[0002] In the field of stamping forming of automotive body panels, as product shapes become increasingly complex and curved surfaces more diverse, the industry generally adopts a process integration design strategy to reduce mold development costs. This involves implementing multiple composite processes within a single mold. However, when a specific area of ​​a part requires simultaneous completion of two key processes—flanging and side forming—traditional mold structures have certain technical limitations. Due to conflicts in the forming force transmission path and motion sequence, flanging and side forming cannot be coordinated and completed at the same workstation. If two processes are used, firstly, it is not economical; secondly, the transfer of parts between multiple processes requires repeated positioning, and accumulated errors can easily lead to mismatches in the forming area, resulting in a decrease in product yield. Existing technologies include devices capable of simultaneously performing side flanging. For example, Chinese patent document CN106111810A discloses a composite flanging mold with a side flanging function. The mold has a side flanging trolley on the lower mold, and a lower drive block that cooperates with the side flanging drive block is installed on the side flanging trolley. The side of the lower drive block is provided with a side flanging cutter block to enable the front flanging process and the side flanging process to be performed simultaneously. However, the above process is performed simultaneously without time separation, which makes it easy to perform side flanging before the product is fully compacted and cannot perform side shaping, resulting in wavy texture at the flanging edge and affecting the flanging quality. Summary of the Invention

[0003] The present invention aims to provide a flanging and side forming structure and method for adjacent positions of an automotive mold, so as to provide a mold flanging mechanism with high surface quality through sequential forming.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an adjacent flanging and side shaping structure for an automotive mold, including an upper mold and a lower mold. The upper mold can be raised and lowered relative to the lower mold. A pressure plate is provided at the center of the upper mold. A lower die for supporting parts is provided on the upper surface of the lower mold. It also includes several elastic resetters. The pressure plate includes a pressure plate connected to the upper mold through the elastic resetter. The lower surface of the pressure plate and the upper surface of the lower die are both arc-shaped surfaces that cooperate with the forming of the parts. A flanging knife is provided on one side of the pressure plate for flanging the edge of the workpiece. The flanging knife is also connected to the upper mold through the elastic resetter. A flanging knife is provided at the bottom of the flanging knife. The bottom of the flanging knife is a flanging blade. In its natural state, the flanging blade is higher than the edge of the pressure plate. A side shaping part is also provided on the side of the lower die near the flanging knife. The side shaping part includes a wedge slidably disposed on the lower mold and a side shaping pressure block fixed on the wedge. An inclined drive block that cooperates with the downward pressing wedge is installed on the bottom surface of the upper mold. The inclined drive block can press down the wedge and push the side shaping pressure block to press the edge of the flanged part laterally.

[0005] The beneficial effects of this solution are as follows: In its natural state, the bottom surface of the flanging blade is higher than the edge of the pressure plate. The pressure plate first presses the part firmly onto the lower die, and then the flanging and side shaping operations are performed. By rationally designing the relative height relationship between the flanging blade and the pressure plate in a phased manner, the bottom surface of the flanging blade is higher than the edge of the pressure plate in its natural state. Thus, during the downward pressing of the upper die, the pressure plate can first press and fix the part onto the lower die, and then the floating flanging blade continues to move downward to achieve the flanging operation.

[0006] Furthermore, the inclined drive block can press down the inclined wedge to push the side shaping pressure block to press the edge of the part after flanging. The inclined drive block driven by the bottom surface of the upper die presses down the inclined wedge in the lower die, driving the side shaping pressure block fixed on the inclined wedge to move to the side of the part, and performing lateral compaction and shaping on the flanged edge. The above settings utilize different stages in the upper die stroke to sequentially trigger the pressing, flanging, and side shaping operations, realizing time-sequential composite forming within a stamping stroke, avoiding the use of multiple molds and multiple stations, and greatly improving mold integration and production efficiency.

[0007] After flanging is completed, both the pressure plate and the flanging cutter are floatingly mounted on the upper die via elastic resetters, providing excellent flexibility and impact absorption. This structure can accommodate minor differences in the thickness and shape of parts and provides flexible cushioning during die closure, reducing the risk of die damage and improving structural reliability and service life.

[0008] This technical solution effectively avoids edge deformation, warping, and ripple problems caused by flanging after the parts are fixed in place, by controlling the sequence of compaction, flanging, and side shaping. This improves the dimensional accuracy and surface quality of the flanging area. This solution continuously completes the three key processes of compaction, flanging, and side shaping in the same station, eliminating intermediate transfer operations and avoiding repetitive positioning and error accumulation caused by process transitions, thus improving shaping matching and product yield.

[0009] Preferably, as an improvement, the lower die has an installation groove on the side near the wedge, and a telescopic cylinder and a filling punch are provided in the installation groove. The filling punch is fixed at the output end of the telescopic cylinder. In the extended state, the upper surface of the filling punch and the lower die together form an arc-shaped surface for forming. In the contracted state, it sinks into the surface of the lower die. The surface of the filling punch relative to the wedge has a forming groove that cooperates with the side forming pressure block.

[0010] The beneficial effects are as follows: A shaping groove is provided on the surface of the filling punch relative to the wedge. The shape of this shaping groove matches the side shaping block. The wedge pushes the side shaping block laterally into the shaping groove, achieving precise pressing and shaping of the part's edge. The filling punch, as the support surface inside the part's flanged area, together with the side shaping block, forms a closed pressing structure. The precise fit between the shaping groove and the block helps to accurately constrain and shape the flanged area, preventing wrinkling or deformation of the material edges and improving forming accuracy and edge linearity. After shaping, the filling punch is lowered by controlling the retraction of the telescopic cylinder, thus creating a demolding gap between the filling punch and the shaped part. This effectively reduces the risk of parts sticking to or jamming the mold, facilitating manual or robotic automatic part removal and improving mold automation and cycle efficiency.

[0011] Preferably, as an improvement, the bottom surface of the upper mold is provided with a first groove for accommodating the pressure plate and a second groove for accommodating the flanging cutter. The flanging cutter also includes a sliding seat. The flanging cutter is disposed at the bottom of the sliding seat. The side wall of the sliding seat is provided with a plurality of first guide blocks. The first guide blocks are all slidably engaged with the second groove in the vertical direction. The top of the sliding seat is connected to the elastic resetter.

[0012] The beneficial effects are as follows: the sliding seat forms a stable sliding guide pair with the second groove of the upper mold through the first guide block, which can ensure that the flanging knife moves stably only in the vertical direction, preventing swaying or tool trajectory deviation caused by lateral force. At the same time, the first guide block can effectively limit the movement posture of the flanging knife, prevent the blade from shaking and vibrating during the pressing process, which is conducive to obtaining a high-quality flanging profile with straight lines and no ripples on the surface, and improving the consistency of the flanging line and the accuracy of angle control.

[0013] Preferably, as an improvement, the lower die surface is provided with a limiting block, and the flanging cutter moves to a set position and abuts against the surface of the limiting block.

[0014] The beneficial effects are: by setting a limiting block in the lower die, the termination position of the flanging cutter can be clearly defined, which can effectively unify the flanging depth and angle. This is especially suitable for automotive body panels with strict requirements for edge folding height, and is conducive to achieving standardized production and product consistency control.

[0015] Preferably, as an improvement, the bottom of the wedge is provided with a slide rail, and the wedge is slidably connected to the lower die through the slide rail.

[0016] The beneficial effects are as follows: the slide rail provides a fixed sliding path for the wedge, ensuring that the wedge can slide stably along the preset angle when subjected to the oblique force of the upper die oblique drive block, preventing the wedge from shifting, getting stuck, or causing skewed movement due to uneven force, ensuring precise pressing and fit between the side shaping pressure block and the filling punch. The wedge sliding with the slide rail constraint is more stable, making the force direction of the side shaping pressure block clear during the forming process and the clamping force evenly distributed, which is conducive to obtaining good flange edge line and flatness.

[0017] Preferably, as an improvement, one side of the inclined drive block is an inclined surface that cooperates with the downward pressing wedge, and a second guide block is fixed on the inclined surface.

[0018] The beneficial effects are as follows: the second guide block, as a guiding element, forms a stable guide with the guide groove set by the wedge, which can effectively prevent the inclined drive block from swaying left and right or misaligning on the inclined surface under high-speed stamping, and ensure that the pressure on the inclined surface is always accurately transmitted to the wedge, thereby ensuring the accuracy and repeatability of subsequent side shaping actions.

[0019] Preferably, as an improvement, the elastic resetter is a nitrogen spring.

[0020] The beneficial effects are as follows: nitrogen springs have the characteristics of constant output force and high stroke consistency, which can provide precise pre-pressure control for the pressure plate and the flanging knife, avoid insufficient compaction or flanging deviation due to uneven or attenuated spring force, and significantly improve the edge quality and dimensional consistency of parts.

[0021] A method for flanging and side forming of adjacent positions in automotive molds, including the following steps: Step 1: Place the part on the lower die; first, the upper die drives the pressure plate to move down and press it onto the lower die to fix the part. The elastic reset device connected to the pressure plate is compressed. Then the upper die continues to move down and the flanging blade flangs the edge of the part. After the flanging blade flangs the part, the flanging blade stops moving down. Step 2: The upper mold continues to descend, driving the inclined drive block to press down. The inclined surface of the inclined drive block contacts the inclined wedge and drives the inclined wedge to slide. The inclined wedge drives the side shaping pressure block to contact the edge of the part after flanging, completing the side shaping of the edge of the part. Attached Figure Description

Detailed Implementation

[0024] The following detailed description is provided through specific implementation methods and examples.

[0025] The preferred embodiments of the present invention are basically as follows: Figures 1-4 As shown, Figure 1 The automotive mold shown includes an adjacent position lower flange and side forming structure, including an upper mold 1 and a lower mold 2. The upper mold 1 can be raised and lowered relative to the lower mold 2. The upper mold 1 is provided with a pressure plater at its center. The upper surface of the lower mold 2 is provided with a lower concave mold 3 for carrying parts. It also includes several elastic resetters 4. In order to make the structure simple, reliable and easy to assemble, the preferred embodiment of the present invention is that the elastic resetters 4 are all nitrogen springs.

[0026] The pressure plate includes a pressure plate 5 that is floatingly connected to the upper mold 1 via an elastic resetter 4. The lower surface of the pressure plate and the upper surface of the lower die are both arc-shaped surfaces that fit the part. The pressure plate 5 and the lower die 3 cooperate to fix the part, and the lower die 3 serves as a bottom support to shape the part. One side of the pressure plate is provided with a flanging cutter for flanging the edge of the workpiece. The bottom of the flanging cutter is provided with a flanging cutter 15, the bottom of which is a flanging edge. The top of the flanging cutter is also floatingly connected to the upper mold 1 via the elastic resetter 4. In its natural state, the flanging blade is higher than the side of the lower surface of the pressure plate 5. The lower die 3 is also provided with a side shaping part on the side near the flanging blade. The side shaping part includes a wedge 6 that is slidably disposed on the lower die 2 and a side shaping pressure block 7 fixed on the wedge 6. The side shaping pressure block 7 can be connected to the wedge 6 by bolt fixing and ensure the stability of the connection. The bottom surface of the upper die 1 is equipped with a slanted drive block 8 that cooperates with the wedge 6 to press down. The slanted drive block 8 can press down the wedge 6 and push the side shaping pressure block 7 to press the edge of the part after flanging.

[0027] In its natural state, the bottom surface of the flanging blade is higher than the edge of the pressure plate 5. First, the pressure plate 5 presses the part firmly onto the lower die 3 and shapes it. Then, the flanging and side shaping operations are performed. By rationally designing the relative height relationship between the flanging blade and the pressure plate 5 in a phased manner, the bottom surface of the flanging blade is higher than the edge of the pressure plate 5 in its natural state. Thus, during the downward pressing of the upper die 1, the pressure plate 5 can first press and fix the part onto the lower die 3. Then, the floating flanging blade 15 continues to descend to achieve the flanging operation. Furthermore, the inclined drive block 8 can press down the inclined wedge 6 to push the side shaping pressure block 7 to press the edge of the part after flanging. The inclined drive block 8 driven by the bottom surface of the upper die 1 presses down the inclined wedge 6 in the lower die 2, driving the side shaping pressure block 7 fixed on the inclined wedge 6 to move to the side of the part, and performing lateral compaction and shaping on the flanged edge. The above setting uses different stages in the stroke of the upper die 1 to sequentially trigger the pressing, flanging and side shaping operations, realizing the time-sequential composite forming within a stamping stroke, avoiding the use of multiple molds and multiple stations, and greatly improving the mold integration and production efficiency.

[0028] This technical solution effectively avoids edge deformation, warping, and ripple problems caused by flanging after the parts are fixed in place, by controlling the sequence of compaction, flanging, and side shaping. This improves the dimensional accuracy and surface quality of the flanging area. This solution continuously completes the three key processes of compaction, flanging, and side shaping in the same station, eliminating intermediate transfer operations and avoiding repetitive positioning and error accumulation caused by process transitions, thus improving shaping matching and product yield.

[0029] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention is as follows: one side of the inclined drive block 8 is an inclined surface that cooperates with the downward pressing wedge 6, and one side of the wedge 6 is an inclined surface that can slide with the inclined drive block 8. A second guide block 19 is fixed on the inclined surface. The second guide block 19 serves as a guiding element and forms a stable guide with the guide groove set in the wedge 6. This can effectively prevent the inclined drive block 8 from swaying left or right or the inclined surface from misaligning under high-speed stamping, ensuring that the pressure of the inclined surface is always accurately transmitted to the wedge 6, thereby ensuring the accuracy and repeatability of subsequent side forming operations. To ensure a smooth sliding path for the wedge 6 and ease of assembly, a slide rail 18 is provided at the bottom of the wedge 6. The wedge 6 is slidably connected to the lower mold 2 via the slide rail 18. The slide rail 18 provides a fixed sliding path for the wedge 6, ensuring that the wedge 6 can slide stably along a preset angle when subjected to the oblique force of the upper mold 1 oblique drive block 8. This prevents the wedge 6 from shifting, getting stuck, or causing skewed movement due to uneven force, and ensures precise pressing and engagement between the side shaping block 7 and the filling punch 10.

[0030] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention is as follows: A mounting groove is provided on the side of the lower die 3 near the wedge 6. A telescopic cylinder 9 and a filling punch 10 are housed within the mounting groove. The filling punch 10 and the telescopic cylinder 9 are in contact via a wedge-shaped guide block. The filling punch 10 is fixedly connected to the output end of the telescopic cylinder 9; the fixed connection method is not limited and can be achieved using bolts. To ensure accurate and smooth sliding of the filling punch 10, a third guide block 20 is fixedly provided on the side of the filling punch 10. The filling punch 10 slides in conjunction with the mounting groove via the third guide block 20. In the extended state, the upper surface of the filling punch 10, together with the lower die 3, forms an arc-shaped surface for forming and supports the part. In the contracted state, it sinks into the surface of the lower die 3. The surface of the filling punch 10 relative to the wedge 6 is provided with a forming groove 11 that cooperates with the side forming pressure block 7.

[0031] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention is that a limiting block 17 is provided on the surface of the lower mold 2. After the flanging blade 15 moves to a set position, it abuts against the surface of the limiting block 17. By setting the limiting block 17 on the lower mold 2, the termination position of the downward pressing of the flanging blade 15 is clearly defined, which can effectively unify the flanging depth and angle.

[0032] A shaping groove 11 is provided on the surface of the filling punch 10 on the side opposite to the wedge 6. The shape of the shaping groove 11 matches the side shaping pressure block 7. The wedge 6 pushes the side shaping pressure block 7 to press laterally into the shaping groove 11, realizing precise pressing and shaping of the edge of the part. The filling punch 10 serves as the support surface inside the flanged area of ​​the part, and together with the side shaping pressure block 7, it forms a pressing structure. The precise matching of the shaping groove 11 and the pressure block helps to accurately constrain and shape the flanged area, prevent wrinkling or deformation of the material edge, and improve forming accuracy and edge linearity. After shaping, the telescopic cylinder 9 is controlled to retract, causing the filling punch 10 to sink, thereby forming a demolding gap between the filling punch 10 and the shaped part. This effectively reduces the risk of the part sticking to the mold or getting stuck, making it easier for manual or robotic arms to automatically pick up the part, and improving the automation and cycle efficiency of the mold.

[0033] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention is as follows: the bottom surface of the upper mold 1 is provided with a first groove 12 for accommodating the pressing template and a second groove 13 for accommodating the flanging cutter. The flanging cutter also includes a sliding seat 14. The flanging cutter 15 is disposed at the bottom of the sliding seat 14. The side wall of the sliding seat 14 is provided with several first guide blocks 16. The first guide blocks 16 are all slidably engaged with the second groove 13 in the vertical direction. The top of the sliding seat 14 is connected to the elastic resetter 4. The sliding seat 14 forms a stable sliding guide pair with the second groove 13 of the upper mold 1 through the first guide blocks 16, which can ensure that the flanging cutter 15 moves stably only in the vertical direction, preventing swaying or tool trajectory deviation caused by lateral force. At the same time, the first guide blocks 16 can effectively limit the movement posture of the flanging cutter 15, preventing the blade from shaking and vibrating during the pressing process, which is conducive to obtaining a high-quality flanging profile with straight lines and no ripples on the surface, and improving the consistency of the flanging line and the accuracy of angle control.

[0034] A method for flanging and side forming of adjacent positions in automotive molds, including the following steps: Step 1: The telescopic cylinder 9 extends, driving the filling punch 10 upward to support the part and place it on the lower die 3; the upper die 1 drives the pressure plate 5 downward to press the part onto the lower die 3, fixing it and shaping it. Figure 2 The elastic resetter 4, which is connected to the pressure plate 5, is compressed under pressure. Step 2: As Figure 3 As shown, the upper mold 1 continues to descend, driving the flanging blade 15 to descend. The flanging blade 15 contacts the edge of the part to perform flanging, causing the edge of the part to fold downward. After the flanging blade completes the flanging, the flanging blade 15 abuts against the limiting block 17 set on the lower mold 2. The limiting block 17 limits the flanging blade 15, causing the flanging blade to stop descending and preventing the flanging blade 15 from interfering with the side shaping block 7. Step 3: As Figure 4As shown, the upper mold 1 continues to descend, driving the inclined drive block 8 to press down. The inclined surface of the inclined drive block 8 contacts the inclined wedge 6 through the third guide block 20 and drives the inclined wedge 6 to slide along the guide rail towards the lower die 3. The inclined wedge 6 drives the side shaping pressure block 7 to contact the edge of the part after flanging, completing the side shaping of the edge of the part. Step 4: The telescopic cylinder 9 uses the surrounding guide plates to drive the filling punch 10 to retract longitudinally, forming a demolding gap between the filling punch 10 and the shaped part, making it easier to remove the part.

[0035] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
