Description

Technical Field

[0001] This utility model belongs to the field of stamping correction forming, and specifically relates to a novel arc-shaped right-angle forming springback correction structure. Background Technology

[0002] In traditional stamping production, the calibration process is a crucial step in ensuring that the dimensional accuracy and shape of parts meet design requirements. The traditional calibration method is usually an insert-type punch face calibration, which involves directly inserting the punch into the die to perform overall calibration of the part. This method can quickly complete the calibration work when the accuracy requirements of the part are not high.

[0003] However, when the product structure is complex and the tolerance requirements are precise, the punch face is directly inserted for correction. Due to the different force forms, the right-angle surface of the product is easily scratched and damaged, and the right-angle part is twisted and deformed, which makes it impossible to achieve the correction and forming effect.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a novel arc-shaped right-angle forming springback correction structure. The inclined wedge punch moves downward, causing the slider to generate a lateral thrust inward. With the positioning of the contour-following support block and several second forming inserts, the product structure is not affected or changed, and the original precision of the parts is guaranteed. At the same time, under the influence of the lateral thrust of the slider, the original springback outward expansion angle of the product is corrected and formed to meet the product size requirements, thus solving the production needs of complex product structures and precise tolerance requirements.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a novel arc-shaped right-angle forming springback correction structure, including a base, a forming positioning plate, a forming springback mechanism, and a lower pressure plate. The forming positioning plate is disposed on the base; a forming springback groove is provided in the middle of the forming positioning plate; the forming springback mechanism is disposed within the forming springback groove; the forming springback mechanism includes a positioning component and a set of correcting forming components; the positioning component is disposed in the middle of the forming springback groove; the correcting forming components are disposed on both sides of the positioning component; the correcting forming component includes a slider and several first forming inserts; the slider is disposed beside the positioning component; the first forming inserts are disposed on the side of the slider near the positioning component; a set of limiting springback components is also provided between the set of correcting forming components; the limiting springback components are disposed at both ends of the positioning component; the lower pressure plate is disposed above the forming positioning plate; several inclined wedge punches are provided on the lower surface of the lower pressure plate. The cooperation of the slider and the limiting springback components enables rapid forming and resetting operations.

[0007] Furthermore, the positioning component, in conjunction with the first forming insert, enables precise positioning of products with irregular curved surfaces, ensuring the original accuracy of the product; the forming springback groove provides space for the springback mechanism, while the limiting springback component effectively controls the springback process; the limiting springback component provides a reliable restoring force to the slider, ensuring that the slider can accurately and quickly return to its initial position after each stamping, reducing the time interval between the end of stamping and the start of the next stamping, and improving production efficiency; the limiting springback component is located at both ends of the positioning component, providing a stable and symmetrical springback force to the slider; the lower pressure plate, in conjunction with the wedge punch, provides the foundation for stamping.

[0008] Furthermore, the positioning component includes a contour placement block and several second molding inserts; the contour placement block is located in the center of the molding springback groove; the second molding inserts are located on both sides of the contour placement block near the correction molding component. The contour placement block is designed according to the shape of the product to adapt to products of different shapes; the combined design of the contour placement block and the second molding inserts ensures that the product is always in a precise positioning state during the molding process, effectively reducing dimensional deviations caused by inaccurate positioning and improving molding accuracy.

[0009] Furthermore, the second molding insert is correspondingly arranged to the first molding insert, and the two work together to complete the product molding. Both the first and second molding inserts can be replaced and adjusted according to the part type and angle changes, allowing for quick switching between the production of different products and improving the adaptability and production efficiency of the equipment.

[0010] Furthermore, the slider has a wedge slot corresponding to the wedge punch; the upper end of the wedge slot has a guide slope. The guide slope provides guidance for the downward movement of the wedge punch, ensuring that it smoothly inserts into the wedge slot and drives the slider to move inward.

[0011] Furthermore, the limiting and rebound assembly includes a limiting block and a return spring; the limiting block is located at both ends of the conforming placement block and between the sliders; the return spring is located inside the limiting block, with its two ends abutting against the sliders on both sides. The limiting block, located at both ends of the conforming placement block, can precisely limit the forming position of the part; the return spring can quickly return the slider to its initial position after stamping, thereby reducing equipment downtime and improving production efficiency.

[0012] Furthermore, a set of pressure blocks is provided between the two ends of the slider; the pressure blocks are located beside the wedge slot and press against the limiting block. During the stamping process, the equipment will vibrate, and the pressure blocks can reduce the shaking of the limiting block caused by vibration, thereby improving the stability of the entire structure and ensuring forming accuracy.

[0013] Furthermore, the end of the limiting block furthest from the positioning component is also provided with a snap-fit ​​strip; the limiting block is snapped into one side of the molding spring groove via the snap-fit ​​strip. Through the snap-fit ​​strip and the molding spring groove, the limiting block can maintain a stable position during the molding process, effectively preventing the limiting block from shifting or loosening under force.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0015] 1. This utility model provides a novel arc-shaped right-angle forming springback correction structure. The inclined wedge punch moves downward, causing the slider to generate a lateral thrust inward. Combined with the positioning of the contour-following support block and several second forming inserts, the product structure is not affected or changed, and the original precision of the parts is guaranteed.

[0016] 2. This utility model provides a novel arc-shaped right-angle forming springback correction structure. Both the first forming insert and the second forming insert can be replaced and adjusted according to the part model and angle changes, which can quickly switch to produce different products and improve the adaptability and production efficiency of the equipment.

[0017] 3. This utility model provides a novel arc-shaped right-angle forming springback correction structure. Under the influence of the lateral thrust of the slider, the original springback outward expansion angle of the product is corrected and formed to meet the product size requirements, thus solving the production needs of complex product structures and precise tolerance requirements.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0030] In this embodiment, as Figure 1 and Figure 2 This utility model discloses a novel arc-shaped right-angle forming springback correction structure, including a base 1, a forming positioning plate 2, a forming springback mechanism 3, and a lower pressure plate 4; the forming positioning plate 2 is disposed on the base 1; a forming springback groove 21 is provided in the middle of the forming positioning plate 2; the forming springback mechanism 3 is disposed in the forming springback groove 21; the forming springback mechanism 3 includes a positioning component 31 and a set of correcting forming components 32; the positioning component 31 is disposed in the middle of the forming springback groove 21; the correcting forming components 32 are disposed in the middle of the forming springback groove 21. The positioning component 31 has two sides; the correction forming component 32 includes a slider 321 and several first forming inserts 322; the slider 321 is located beside the positioning component 31; the first forming inserts 322 are located on the side of the slider 321 near the positioning component 31; a set of limiting spring-loaded components 33 is also provided between a set of the correction forming components 32; the limiting spring-loaded components 33 are located at both ends of the positioning component 31; the lower pressure plate 4 is located above the forming positioning plate 2; the lower surface of the lower pressure plate 4 is provided with several inclined wedge punches 41.

[0031] Specifically, the connection between the first molding insert 322 and the slider 321 can be achieved by using a quick connection method such as magnetic connection or snap-fit ​​connection, which reduces the time for changing inserts and improves production efficiency.

[0032] Specifically, it is preferable to have several forming springback grooves 21 on the forming positioning plate 2. At the same time, the number of forming springback mechanism 3 and inclined wedge punch 41 is also increased accordingly to expand the production scale and process several products at the same time in one operation.

[0033] In particular, it is preferable to add a sensor inside the forming spring groove 21 to detect whether the slider 321 has been successfully reset, so as to prevent its failure to reset from affecting the next operation.

[0034] In particular, the wedge punch 41 can be designed as an adjustable structure as a preferred option, with screws or hydraulic cylinders added to adjust the position and angle of the wedge punch 41 to adapt to different stamping requirements.

[0035] In this embodiment, as Figure 1 and Figure 2 The positioning component 31 includes a contour placement block 311 and a plurality of second molding inserts 312; the contour placement block 311 is located in the middle of the molding spring groove 21; the second molding inserts 312 are located on both sides of the contour placement block 311 near the correction molding component 32.

[0036] Specifically, the following is an optional solution: design a threaded hole in the middle of the forming spring groove 21, design a threaded hole in the bottom of the contour placement block 311, and install the contour placement block in the middle of the forming spring groove with screws.

[0037] Specifically, the second molding insert 312 and the contour placement block 311 are preferably connected by snap-fit ​​on the side, which makes it easy to change the model of the second molding insert 312 when dealing with different models of parts.

[0038] In this embodiment, as Figure 1 and Figure 2 The second molding insert 312 is correspondingly provided with the first molding insert 322, and the two work together to complete the molding of the product.

[0039] Specifically, both the first molding insert 322 and the second molding insert 312 can be replaced and adjusted according to the part type and angle changes.

[0040] In this embodiment, as Figures 1 to 4 The slider 321 is provided with a wedge slot 323 corresponding to the wedge punch 41; the upper end of the wedge slot 323 is provided with a guide slope 3231.

[0041] Specifically, such as Figure 4 When the wedge punch 41 is not inserted into the wedge slot 323, the wedge punch 41 is slightly close to the side of the wedge slot 323 with the guide slope 3231 in the vertical direction, so as to ensure that when the wedge punch 41 moves downward, it contacts the guide slope 3231 as soon as possible, and drives the slider 321 to move inward.

[0042] In this embodiment, as Figure 1 and Figure 2The limiting and rebounding assembly 33 includes a limiting block 331 and a return spring 332; the limiting block 331 is located at both ends of the conformal placement block 311 and between the sliders 321; the return spring 332 is located inside the limiting block 331 and its two ends abut against the sliders 321 on both sides respectively.

[0043] Specifically, it is preferable to design a spring mounting hole inside the limit block 331, with the diameter of the hole matching the outer diameter of the return spring 332; it is also preferable to add a layer of buffer material such as a rubber pad between the limit block 331 and the slider 321 to reduce wear and impact.

[0044] In this embodiment, as Figure 1 and Figure 2 A set of pressure blocks 34 is provided between the two ends of the slider 321; the pressure blocks 34 are located on the side of the wedge slot 323 and press on the limiting block 331.

[0045] Specifically, such as Figure 2 The pressure block 34 can be designed as a rectangular block, and a screw can be designed at each end of the pressure block 34. The pressure block 34 can be installed on the molding positioning plate 2 by screws to ensure that the pressure block 34 is stably pressed on the limiting block 331 and the slider 321.

[0046] In this embodiment, as Figure 1 and Figure 2 The end of the limiting block 331 away from the positioning component 31 is also provided with a snap-fit ​​strip 3311; the limiting block 331 is snapped into one side of the molding spring groove 21 through the snap-fit ​​strip 3311.

[0047] Specifically, the shape of the snap-fit ​​strip 3311 can be strip-shaped, block-shaped, or other suitable snap-fit ​​shape, and its size should fit tightly with the snap-fit ​​groove in the molding spring groove to ensure that the limiting block 331 will not loosen after snap-fit; the length of the snap-fit ​​strip 3311 can be adjusted according to the size of the limiting block 331 and the depth of the molding spring groove 21 to ensure sufficient snap-fit ​​strength.

[0048] The working principle of the above embodiments is as follows:

[0049] This utility model discloses a novel arc-shaped right-angle forming springback correction structure. When the mold moves from the open state to the closed state, the wedge punch 41 moves downward, pushing the slider 321 inward. The slider 321 drives the first forming insert 322 to press the product to be corrected, so that its inner side fits against the contour placement block 311, and is supported by the second forming insert 312 to ensure its original accuracy. The first forming insert 322 continues to move inward, so that the right-angle bend of the product part is corrected by force. After this correction process is completed, the wedge punch 41 moves upward, and the return spring 332 generates elastic force on both sides, so that the slider 321 moves outward to return to its original position.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
