Description

Technical Field

[0001] This invention relates to the field of automotive parts forming equipment technology, and in particular to a reinforcing beam forming process and its mold structure. Background Technology

[0002] Reinforcing beams are common components in truck cabs and are crucial safety features. With lightweighting becoming a mainstream trend in automotive design, cab components are increasingly thinner, making the cab's strength more vulnerable. Reinforcing beams are essential to maintain overall cab strength, requiring them to meet stringent strength requirements. Since these beams are typically located inside the cab and need to avoid contact with other functional components, their shapes are often extremely complex, making molding very difficult and requiring a drawing process to ensure quality and precision. However, drawing processes have low material utilization and require subsequent trimming and punching steps, increasing the number of molds and development costs. Production also requires more manual labor, equipment, and energy, hindering cost control. While using a molding die structure can reduce the number of molds and development costs, saving labor, equipment, and energy, this method often results in defects such as wrinkling, cracking, and material stacking for such complex reinforcing beams. How to effectively reduce production costs while ensuring the quality and precision of the reinforcing beams has become one of the problems that plagues major mold manufacturers. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a novel reinforcing beam forming mold and forming process.

[0004] An embodiment of the present invention provides a novel reinforcing beam forming mold, comprising an upper mold base and a lower mold base;

[0005] The upper die base is provided with at least two upper punches, and an upper pressing core assembly is attached around each upper punch. Each upper pressing core assembly is driven by a driving component to move up and down along the wall surface of the corresponding upper punch.

[0006] The lower die base is equipped with at least two lower ejector cores, each of which corresponds to one of the upper punches. A lower die flanging cutter block assembly is attached around each lower ejector core. Each lower ejector core and the corresponding lower die flanging cutter block assembly together form a forming groove that cooperates with the corresponding upper punch. Each lower ejector core can move up and down along the wall of the corresponding lower die flanging cutter block assembly driven by an external machine tool. Two product positioning pins are provided on the upper end face of each lower ejector core, and several lower die product positioning plates are provided on each lower die flanging cutter block assembly. Each lower die product positioning plate and each product positioning pin cooperate with each other to perform rough positioning and fine positioning of the blank to be formed.

[0007] Furthermore, each of the upper punches is provided with a plurality of upper die product positioning plates, and each of the upper die product positioning plates cooperates with each of the lower die product positioning plates and each of the product positioning pins to perform rough positioning and fine positioning of the blank.

[0008] Furthermore, each of the upper pressure core assemblies has one side attached to the corresponding upper punch wall and the other side equipped with a guide panel, and each guide panel is fixedly mounted on the upper die base.

[0009] Furthermore, one end of each upper pressure core assembly along its vertical movement direction is attached to the upper mold base and is equipped with a limiting screw, while the other end faces the lower mold base. Each spring is disposed inside the upper mold base and is driven connected to the corresponding end of the corresponding upper pressure core assembly. Each limiting screw is disposed inside the upper mold base and is limited connected to the corresponding end of the corresponding upper pressure core assembly.

[0010] Furthermore, the lower mold base is provided with a cavity for accommodating each of the lower ejector cores. One end of each lower ejector core is accommodated in the corresponding cavity, and the other end faces the upper mold base. A mold base pad is provided at the end of each cavity away from the upper mold base. Each mold base pad is fixedly connected to the lower mold base and abuts against the end of the corresponding lower ejector core located in the corresponding cavity. An external machine tool drive end passes through each mold base pad and is driven to connect to the corresponding end of each lower ejector core.

[0011] Furthermore, each of the lower ejector cores is provided with limiting brackets on both sides of one end located in the corresponding cavity, so that when each of the lower ejector cores is driven by an external machine tool, the limiting brackets cooperate with the lower mold base to prevent the lower ejector core from directly detaching from the corresponding cavity.

[0012] Furthermore, the driving element is a spring.

[0013] It also includes a reinforcing beam forming process, using the aforementioned novel reinforcing beam forming mold, comprising the following steps:

[0014] S1. According to the actual dimensions of the new reinforcing beam, the raw material of the plate is cut to form a blank to be formed, and two positioning holes are punched out at the same time as the blank is cut.

[0015] S2. Each of the lower ejector cores is ejected from the corresponding cavity to a first set height by an external machine tool. Then the blank is placed on the upper surface of each of the lower ejector cores. The product positioning pins pass through the corresponding two positioning holes and are combined with the lower mold product positioning plates to form rough and fine positioning of the blank before molding.

[0016] S3. Drive each of the upper pressure core groups to push out to a second set height by each of the springs. Then the entire upper mold base moves down under the drive of an external machine tool until the upper mold product positioning plate forms a secondary relative fixation on the blank to be formed.

[0017] S4. The upper mold base continues to move downward, each of the upper pressing core groups retracts synchronously, and each of the lower ejector cores retracts synchronously, so that each of the upper pressing core groups contacts each of the lower mold flanging block groups, thereby forming pressing and bending plasticity on both ends of the blank.

[0018] S5. The upper mold base continues to descend, each of the upper pressing core groups continues to retract synchronously, and each of the lower ejector cores continues to retract synchronously, so that the upper punch and the upper end face of the lower ejector cores contact and press the blank, until the upper punch enters the groove. At this time, each of the upper pressing core groups and each of the lower ejector cores retracts into place and is locked, and the product is finally formed.

[0019] S6. Drive the entire upper mold base upward by an external machine tool, and then drive each of the lower ejector cores to be lifted again by an external machine tool, thereby ejecting the final formed product from the groove and manually removing the part;

[0020] S7. Repeat steps S2 to S6 above to produce in a cycle.

[0021] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: The novel reinforcing beam forming mold and forming process of the present invention, through the improvement of the mold structure and forming process, firstly, during forming stamping, the blank to be formed is positioned by the product positioning plates of each lower mold, the product positioning pins of each product, and the product positioning plates of each upper mold. In this way, the blank is fixed at the beginning of stamping and forming, avoiding movement during subsequent forming. Then, the upper and lower mold bases are controlled to move up and down, so that each upper pressure core group and each mold flange block group contact after moving up and down, thereby forming pressure and bending plasticity around the blank. In this way, wrinkling and stacking of the product can be effectively prevented when stamping the two ends of the blank. Then, the upper and lower mold bases are controlled to move up and down, and finally the product is formed. In general, it effectively reduces the number of molds developed, reduces the number of operators, saves production equipment and reduces energy consumption, while ensuring the smooth operation of production safely and effectively, and can overcome forming defects such as no wrinkling, no cracking, and no stacking.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0033] Please refer to Figures 1 to 7 The present invention provides a reinforcing beam forming mold and forming process. The mold includes an upper mold base 1 and a lower mold base 2. In actual operation, the upper mold base 1 and its components cooperate with the lower mold base 2 and its components to complete the stamping forming work.

[0034] Please refer to Figure 2 and Figure 3At least two upper punches 3 are provided on the working surface of the upper mold base 1. In this embodiment, there are two upper punches 3, and the two upper punches 3 are symmetrically arranged on the working surface of the upper mold base 1. At the same time, each upper punch 3 is fixed to the working surface of the upper mold base 1 by screws and pins, and each upper punch 3 has upper mold backing keys 4 at both ends. When each upper punch 3 is installed, each upper mold backing key 4 is used to adjust each upper punch 2 during the installation process to meet the requirements. It should be noted that the use of upper mold backing keys 4 is a relatively common prior art in the mold field, so it will not be described in detail here.

[0035] Each upper punch 3 is fixedly provided with several upper die product positioning plates 7. The main function of each upper die product positioning plate 7 is to relatively fix the blank during subsequent stamping. In this embodiment, the number of upper die product positioning plates 7 on each upper punch 3 is four, and they are symmetrically arranged along the corresponding upper punch 3.

[0036] Each upper punch 3 is surrounded by an upper pressure core assembly 5, and each upper pressure core assembly 5 can move up and down along the wall of the corresponding upper punch 3 under power drive. In this embodiment, the upper pressure core assembly 5 around each upper punch 3 includes four upper pressure cores, and these upper pressure cores are symmetrically distributed on both sides of the corresponding upper punch 3. Each upper pressure core can move up and down along the wall of the corresponding upper punch 3 under power drive.

[0037] It should be noted that the dimensions of the upper blanking cores around each upper punch 3 can be different, as long as they meet the stamping requirements, and are not limited by the accompanying drawings of this embodiment.

[0038] One side of each upper pressure core assembly 5 is attached to the outer wall of the corresponding upper punch 3 and can move up and down, while the other side is equipped with a guide panel 6. Each guide panel 6 is fixed on the upper mold base. In this embodiment, the two sides of each upper pressure core assembly 5 can move up and down along the outer wall of the corresponding upper punch 3 and the corresponding guide panel 6, respectively.

[0039] It should be noted that, in this embodiment, each upper pressing core group 5 includes four upper pressing cores, and each upper pressing core needs to be equipped with a corresponding guide panel 6.

[0040] Please refer to Figure 3Each upper pressure core assembly 5 has one end close to the working surface of the upper mold base 1 and the other end facing the lower mold base 2. A spring 10 corresponding to each upper pressure core assembly 5 is installed inside the working surface of the upper mold base 1. Each spring 10 provides power to its corresponding upper pressure core assembly 5. Each spring 10 is housed in the working surface of the upper mold base 1 and is driven connected to the end of the corresponding upper pressure core assembly 5 close to the working surface of the upper mold base 1. Simultaneously, a limiting screw 11 corresponding to each upper pressure core assembly 5 is also installed inside the working surface of the upper mold base 1. Each limiting screw 11... The function of 1 is to prevent the corresponding upper pressure core assembly 5 from being driven away from the upper mold base 1 by the corresponding spring 10; each limiting screw 11 is housed on the working surface of the upper mold base 1 and is fixedly connected to the end of the corresponding upper pressure core assembly 5 near the working surface of the upper mold base 1. It should be noted that each limiting screw 11 can be regarded as a telescopic limiting device, with one end fixedly connected to the upper mold base 1 and the other end fixedly connected to the end of the corresponding upper pressure core assembly 5 near the working surface of the upper mold base 1, and the upper pressure core assembly 5 is limited according to the extension length of the spring 10.

[0041] The upper die base 1 has upper die end 8 at both ends, and the inner side of each upper die end 8 is an end guide surface 9. The main function of each upper die end 8 and each end guide surface 9 is to facilitate the fit between the upper die and the lower die during stamping.

[0042] Please refer to Figure 4 The lower die base 2 has lower die end 16 at both ends, and each lower die end 16 corresponds to each upper die end 8. The wall surface of each lower die end 16 is provided with a surface that matches the end guide surface 9 in the corresponding upper die end 8. In actual working conditions, when stamping, the upper die base 1 and the lower die base 2 fit together, and the two upper die ends 8 on the upper die base 1 are respectively housed in the two lower die ends 16 in the lower die base 2.

[0043] Please refer to Figure 5The working surface of the lower mold base 2 is provided with at least two cavities 15. In this embodiment, there are two cavities 15, which are symmetrically arranged. Each cavity 15 contains a lower ejector core 12. Each lower ejector core 12 is adapted to the corresponding cavity 15, and the lower end of each lower ejector core 12 is located in the corresponding cavity 15, while the other end extends out of the corresponding cavity 15. Each lower ejector core 12 can move up and down along the wall of the corresponding cavity 15 under drive, and each lower ejector core 12 corresponds one-to-one with each upper punch 3. At the same time, a lower mold flanging cutter block assembly 13 is attached around each lower ejector core 12. Each lower mold flanging cutter block assembly 13 is fixedly set on the working surface of the lower mold base 2. The core 12 and the corresponding lower die flanging cutter block group 13 together form a forming groove that cooperates with the corresponding upper punch 3. Similarly, each lower die flanging cutter block group 13 is equipped with a lower die backing key 20 during installation. The function of each lower die backing key 20 is the same as that of each upper die backing key 4, which is to adjust the installation of each lower die flanging cutter block group 13. In this embodiment, each lower die flanging cutter block group 13 includes six lower die flanging cutters, and these lower die flanging cutters are evenly and symmetrically arranged around the corresponding lower top core 12. At the same time, each lower top core 12 moves up and down by relying on the wall surface of the corresponding cavity 15 and the wall surface of the corresponding lower die flanging cutter block group 13.

[0044] Each lower die flanging cutter block assembly 13 is fixedly provided with a number of lower die product positioning plates 14. In this embodiment, the number of lower die product positioning plates 14 on each lower die flanging cutter block assembly 13 is four. Similarly, the function of each lower die product positioning plate 14 is to relatively fix the blank during stamping. At the same time, each lower ejector core 12 is provided with two product positioning pins on the end face of one end extending from the corresponding cavity 15. The function of each product positioning pin is to cooperate with each lower die product positioning plate 14 to better fix the blank to be stamped.

[0045] Please refer to Figure 6 and Figure 7 Each cavity 15 is equipped with a mold base plate 17 at the end away from the upper mold base 1. Each mold base plate 17 is fixedly connected to the bottom surface of the lower mold base 2, so that the corresponding lower ejector core 12 can be limited in the corresponding cavity 15. The end of each lower ejector core 12 located in the corresponding cavity 15 contacts and abuts against the corresponding mold base plate 17. At the same time, a balance block 18 is connected to the end of each lower ejector core 12 located in the corresponding cavity 15. The end of each lower ejector core 12 located in the corresponding cavity 15 is connected to the output end of an external machine tool through the balance block 18 on that end, thereby obtaining power to move up and down in the corresponding cavity 15.

[0046] Each ejector core 12 is provided with a limiting platform 19 on both sides of one end of the corresponding cavity 15. The limiting platform 19 on each ejector core 12 and the upper end of the corresponding cavity 15 form a limiting relationship, thereby preventing the ejector core 12 from completely disengaging when it moves up and down in the corresponding cavity 15 driven by an external machine tool.

[0047] Please refer to Figure 8 and Figure 9 This embodiment also provides a process method for stamping using the above-mentioned mold, the method including the following steps:

[0048] S1. The raw material of the plate is cut into blanks according to the actual size of the new reinforcing beam to form a blank to be formed, and two positioning holes are punched out at the same time as the blank is cut.

[0049] Specifically, in actual working conditions, the raw materials used for stamping are mostly square plates. Therefore, the raw materials are first blanked and punched according to the actual size of the new reinforcing beam to be produced to form the blank to be used. It should be noted that the blank should be generated in accordance with the existing blanking and punching methods. At the same time as the blank is blanked, two positioning holes are punched out, and the position of the two positioning holes is adapted to the position of the two product positioning pins on each lower top core 12.

[0050] S2. Each of the lower ejector cores is ejected from the corresponding cavity to a first set height using an external machine tool. Then, the blank is placed on the upper surface of each of the lower ejector cores, and the blank is roughly and finely positioned before molding by passing through the corresponding two positioning holes and the lower mold product positioning plates of each product positioning pin.

[0051] Specifically, an external machine tool is controlled to eject the two lower ejector cores 12 from their respective cavities 15 to a first set height, which in this embodiment is 50mm. Then, the blank is placed on the upper surface of each lower ejector core 12, and the two positioning holes on the blank pass through the two product positioning pins on each lower ejector core 12. At the same time, the product positioning plates 14 of each lower die cooperate with it, thereby better fixing the blank placed on it and avoiding the problem of blank movement during subsequent stamping.

[0052] S3. Drive each of the upper pressure core groups to push out to a second set height by each of the springs. Then, the entire upper mold base moves down under the drive of an external machine tool until the upper mold product positioning plate forms a secondary relative fixation on the blank to be formed.

[0053] Specifically, after the blank is placed, each spring 10 pushes each upper pressure core assembly 5 out to a second set height. In this embodiment, the second set height is 30mm. Then, the entire upper mold base 1 moves downward, and the end guide surface 9 in the upper mold end 8 contacts the lower mold end 16. After that, the entire upper mold base 1 continues to move downward, and each upper mold product positioning plate 7 contacts the blank for secondary pre-positioning. This is mainly to prevent the blank from shifting due to large shape changes during the subsequent product molding process, which would affect the final size of the product.

[0054] S4. The upper die holder 1 continues to descend, each upper pressing core group 5 retracts synchronously, and each lower ejector core 12 retracts synchronously, so that each upper pressing core group 5 contacts each lower die flanging blade group 13, thereby forming pressing and bending plasticity around the blank.

[0055] Specifically, the upper mold base 1 continues to descend. At the same time, each upper pressure core assembly 5 retracts under the action of each spring 10, and each lower ejector core 12 retracts under the action of the external machine tool. It should be noted that all actions work in concert throughout the process. During the process, each upper pressure core assembly 5 begins to contact the product blank. At the same time, neither the lower ejector core 12 nor the upper pressure core assembly 5 has retracted to its full position. Subsequently, each upper pressure core assembly 5 squeezes the blank to bend and shape it. It should be noted that at this time, only the upper pressure core assembly 5 squeezes and shapes the periphery of the blank. Finally, under the overall action, each upper pressure core assembly 5 moves to contact with each lower mold flanging cutter block assembly 13, thereby clamping the product blank between them to generate pressure and prevent the product from wrinkling and stacking. It should be noted that at this time, neither the lower ejector core 12 nor the upper pressure core assembly 5 has retracted to its full position, but the periphery of the blank has been clamped by each upper pressure core assembly 5 and each lower mold flanging cutter block assembly 13.

[0056] S5. The upper mold base continues to descend, each upper pressure core group continues to retract synchronously, and each lower ejector core continues to retract synchronously, so that the upper end face of the upper punch and the lower ejector core contacts and presses down on the blank, until the upper punch enters the groove. At this time, each upper pressure core group and each lower ejector core retracts into place and is locked in place, and the product is finally formed.

[0057] Specifically, the upper mold base 1 continues to descend, and at the same time, each upper pressing core assembly 5 continues to retract under the action of each spring 10, and each lower ejector core 12 continues to retract under the action of the external machine tool. In the whole action, firstly, the upper punch 3 contacts the blank and presses the blank with the upper end face of each lower ejector core 12. Then, in the continued action, the upper punch 3 enters the groove formed by each lower ejector core 12 and each lower mold flanging cutter block assembly 13. At this time, each upper pressing core assembly 5 and each lower ejector core 12 retracts into place and is locked, and the product is finally formed.

[0058] S6. Drive the entire upper mold base upwards using an external machine tool, and then drive each lower ejector core to be lifted again using an external machine tool, thereby ejecting the final formed product from the groove and manually removing the part.

[0059] Specifically, after the product is formed, the upper mold base 1 moves upward, and then each lower ejector core 12 is ejected again by an external machine tool, thereby ejecting the formed product from the groove. After that, the part is manually removed, and the product forming is completed in one go.

[0060] S7. Repeat steps S2 to S6 above to produce in a cycle.

[0061] By applying the novel reinforcing beam forming process and mold structure of this invention, the supplementary process is completely eliminated. The blank is directly blanked, punched, and formed, which, compared to the drawing forming process that requires drawing followed by trimming, punching, flanging, and shaping, reduces the number of molds required. Furthermore, the process and mold structure in this solution pre-bend the product blank before forming using the upper pressure core, effectively suppressing wrinkle-prone areas and controlling the flow of the blank during forming. In addition to the existing product positioning pins and positioning plates in the lower mold, an upper mold product positioning plate is added, effectively solving the problem of blank movement during forming and causing unstable positioning. This not only solves the problems of wrinkling, cracking, and stacking that easily occur in traditional structures due to excessive part undulation, but also allows the product to be formed in one step, eliminating the need for subsequent trimming, punching, and shaping processes due to blank movement causing dimensional instability. Thus, significant savings in equipment and labor costs are achieved while maintaining quality and quantity.

[0062] In this document, the directional terms such as front, back, top, and bottom are defined based on the location of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.

[0063] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
