[0001] This utility model relates to the field of automotive equipment technology, specifically to a front anti-collision beam stamping device. Background Technology

[0002] As an indispensable and crucial component of a vehicle's safety system, the quality and precision of the front bumper beam directly affect the overall safety performance of the vehicle and profoundly impact the safety of passengers in a collision. As the first line of defense in a vehicle's collision protection, the design, manufacturing, and installation precision of the front bumper beam must meet extremely high standards to ensure that it can effectively absorb and disperse impact energy in a frontal collision, reducing the impact on the vehicle's structure and thus maximizing the protection of the passenger compartment's integrity, providing passengers with a precious survival space.

[0003] Existing front bumper beam stamping devices typically use fixed mold structures for stamping. Once stamping is complete, the entire mold must be disassembled to remove the stamped part. This process is complex, cumbersome, inconvenient to operate, time-consuming, and prone to mold damage, affecting production efficiency. Furthermore, existing stamping devices often suffer from poor adaptability, complex adjustments, and low production efficiency, making it difficult to meet the diverse and high-precision requirements of the modern automotive manufacturing industry for front bumper beams. Utility Model Content

[0004] The purpose of this invention is to provide a front anti-collision beam stamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front anti-collision beam stamping device, comprising a stamping table, a stamping base, and a stamping head. Rectangular slots are provided on both sides of the top of the stamping table. A junction box is fixedly installed at the bottom of the stamping table. An electromagnet is fixedly installed inside the top of the junction box. A spring is fixedly installed on the top of the junction box. An impact head is fixedly installed at the end of the spring away from the junction box. A vertical plate is fixedly installed on the top of the stamping table. A top plate is fixedly installed at the end of the vertical plate away from the stamping table. A stamping cylinder is fixedly installed on the top of the top plate. A connecting plate is fixedly installed on the outer side of the output end of the stamping cylinder. Rectangular rods are fixedly installed at the bottom of both ends of the connecting plate. A junction piece is fixedly installed at the end of the rectangular rod away from the connecting plate and inside the rectangular slot. A stamping groove is provided on the top of the stamping base. An assembly sleeve is fixedly installed on the top of the stamping head.

[0006] Preferably, the assembly sleeve is fitted onto the outside of the output end of the stamping cylinder, and both the assembly sleeve and the output end of the stamping cylinder are provided with circular insertion holes, and a plug is inserted into the inside of the circular insertion hole.

[0007] Preferably, mounting grooves are provided on both sides of the top of the stamping table, and mounting strips are fixedly installed on both sides of the stamping base, with the mounting strips slidably installed on the inner side of the mounting grooves.

[0008] Preferably, the bottom of the stamping seat is provided with a circular groove, the impact head is located directly below the circular groove, the bottom terminals of the two rectangular rods are connected by wires, and the terminals inside the two rectangular grooves are connected to the junction box by wires.

[0009] Preferably, the two rectangular rods are located directly above the two rectangular slots, and the outer contour of the rectangular rods is smaller than the inner contour of the rectangular slots.

[0010] Preferably, the bottom of the stamping table is fixedly equipped with four support legs, which are installed in a rectangular symmetrical arrangement at the four corners of the bottom of the stamping table.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by separating the electrical contact piece at the bottom of the rectangular rod from the electrical contact piece inside the rectangular groove, the electrical contact box stops supplying power to the electromagnet, and the electromagnet stops generating attraction force to the impact head. Under the elastic force generated by the spring's recovery deformation, the impact head can be driven to move upward, thereby accurately striking the bottom of the stamping seat, thereby stimulating a vibration effect. The vibration can effectively break the adhesion between the stamped steel plate and the inner wall of the stamping groove at the top of the stamping seat, so that the steel plate can be smoothly separated from the inner wall of the stamping groove, thus greatly simplifying the demolding process and improving the convenience and efficiency of operation.

[0012] The assembly sleeve and plug-in bolts facilitate easy replacement of the stamping head, while the mounting grooves and sliding bars allow for convenient replacement of the stamping seat. This enables the stamping of steel plates required for automotive crossbeams of different sizes, enhancing the device's versatility. By adjusting the size, shape, and layout of the stamping groove on the top of the stamping seat and the stamping head, the device can flexibly adapt to various specifications of automotive crossbeam steel plates, ensuring that every stamping operation meets the required precision. Whether the automotive crossbeam steel plates are large or small, or have special shapes, the device can handle them with ease, providing automakers with an efficient and reliable stamping solution.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a front anti-collision beam stamping device, including a stamping table 1, a stamping base 2, and a stamping head 3. Rectangular slots 6 are provided on both sides of the top of the stamping table 1. A junction box 13 is fixedly installed at the bottom of the stamping table 1. An electromagnet 21 is fixedly installed inside the top of the junction box 13. A spring 20 is fixedly installed on the top of the junction box 13. An impact head 19 is fixedly installed at the end of the spring 20 away from the junction box 13. A vertical plate 4 is fixedly installed on the top of the stamping table 1. A top plate 9 is fixedly installed at the end of the vertical plate 4 away from the stamping table 1. A stamping cylinder 10 is fixedly installed on the top of the top plate 9. A connecting plate is fixedly installed on the outer side of the output end of the stamping cylinder 10. 8. Rectangular rods 7 are fixedly installed at the bottom of both ends of the connecting plate 8. Electrical contact pieces 16 are fixedly installed at the end of the rectangular rods 7 away from the connecting plate 8 and inside the rectangular groove 6. A stamping groove 5 is opened on the top of the stamping seat 2. An assembly sleeve 14 is fixedly installed on the top of the stamping head 3. A circular groove 18 is opened at the bottom of the stamping seat 2. The impact head 19 is located directly below the circular groove 18. The electrical contact pieces 16 at the bottom of the two rectangular rods 7 are connected by wires. The electrical contact pieces 16 inside the two rectangular grooves 6 are connected to the electrical contact box 13 by wires. The two rectangular rods 7 are located directly above the two rectangular grooves 6 respectively. The outer contour of the rectangular rods 7 is smaller than the inner contour of the rectangular groove 6.

[0020] The working principle of the above technical solution is as follows: First, the stamping seat 2 is installed on the top of the stamping table 1, and the stamping head 3 is installed on the output end of the stamping cylinder 10. Then, the steel plate is placed on the top of the stamping table 1 and the stamping seat 2, and the steel plate is positioned directly above the stamping groove 5. After connecting the external power supply, the stamping cylinder 10 is started. The output end of the stamping cylinder 10 can push the stamping head 3 downward, thereby cooperating with the stamping groove 5 to stamp the steel plate and stamp it into the required shape. In addition, when the output end of the stamping cylinder 10 pushes the stamping head 3 downward, it can drive the connecting plate 8 downward, thereby driving the rectangular rod 7 downward and inserting the rectangular rod 7 into the inside of the rectangular groove 6. This allows the contact piece 16 at the bottom of the rectangular rod 7 to contact the contact piece 16 inside the rectangular groove 6, thereby allowing the junction box 13 to supply power to the electromagnet 21, thus making the electromagnet 21 magnetic. The impact head 19 is attracted, which compresses the spring 20. After the stamping head 3 finishes stamping the steel plate, the output end of the stamping cylinder 10 drives the stamping head 3 to move upward, which in turn drives the connecting plate 8 to move upward. This causes the electrical contact piece 16 at the bottom of the rectangular rod 7 to separate from the electrical contact piece 16 inside the rectangular groove 6, thus stopping the electrical box 13 from supplying power to the electromagnet 21 and stopping the electromagnet 21 from generating attraction to the impact head 19. Under the elastic force generated by the spring 20 restoring its deformation, the impact head 19 can be driven to move upward, thereby accurately striking the bottom of the stamping seat 2. This generates a vibration effect, which can effectively break the adhesion between the stamped steel plate and the inner wall of the stamping groove 5 at the top of the stamping seat 2, allowing the steel plate to separate smoothly from the inner wall of the stamping groove 5. This greatly simplifies the demolding process and improves the convenience and efficiency of operation.

[0021] In another implementation scheme, such as Figures 1-4 As shown, the assembly sleeve 14 is sleeved and installed on the outside of the output end of the stamping cylinder 10. Both the assembly sleeve 14 and the output end of the stamping cylinder 10 are provided with circular insertion holes, and the insertion bolts 15 are inserted and installed inside the circular insertion holes. The top of the stamping table 1 is provided with mounting grooves 11 on both sides. The stamping seat 2 is fixedly installed with mounting strips 17 on both sides. The mounting strips 17 are slidably installed on the inside of the mounting grooves 11.

[0022] The assembly sleeve 14 and plug 15 facilitate the replacement of the stamping head 3, while the mounting groove 11 and mounting slide 17 facilitate the replacement of the stamping seat 2. This allows for the convenient stamping of steel plates required for automotive crossbeams of different sizes, enhancing the device's versatility. By adjusting the size, shape, and layout of the stamping groove 5 on the top of the stamping seat 2 and the stamping head 3, the device can flexibly adapt to various specifications of automotive crossbeam steel plates, ensuring that every stamping operation meets the precision requirements. Whether the automotive crossbeam steel plates are large or small, or have special shapes, the device can easily handle them, providing automotive manufacturers with an efficient and reliable stamping solution.

[0023] In another implementation scheme, such as Figures 1-4 As shown, a support leg 12 is fixedly installed at the bottom of the stamping table 1. There are four support legs 12, and the four support legs 12 are installed in a rectangular symmetrical arrangement at the four corners of the bottom of the stamping table 1.

[0024] The device can be supported by four support legs 12, which improves the device's performance.

[0025] Working principle: First, the stamping base 2 is installed on top of the stamping table 1, and the stamping head 3 is installed at the output end of the stamping cylinder 10. Then, the steel plate is placed on top of the stamping table 1 and the stamping base 2, with the steel plate directly above the stamping groove 5. After connecting the external power supply, the stamping cylinder 10 is started. The output end of the stamping cylinder 10 can push the stamping head 3 downward, thereby stamping the steel plate in conjunction with the stamping groove 5 to form the required shape. In addition, when the output end of the stamping cylinder 10 pushes the stamping head 3 downward, it can drive the connecting plate 8 downward, thereby driving the rectangular rod 7 downward. Furthermore, the rectangular rod 7 is inserted into the rectangular slot 6, causing the contact piece 16 at the bottom of the rectangular rod 7 to contact the contact piece 16 inside the rectangular slot 6. This allows the junction box 13 to supply power to the electromagnet 21, making the electromagnet 21 magnetic and generating an attractive force on the impact head 19, thereby compressing the spring 20. After the stamping head 3 finishes stamping the steel plate, the output end of the stamping cylinder 10 drives the stamping head 3 upward, which in turn moves the connecting plate 8 upward, causing the contact piece 16 at the bottom of the rectangular rod 7 to separate from the contact piece 16 inside the rectangular slot 6, thus stopping the junction box 13. The electromagnet 21 is de-energized, preventing it from generating suction force on the impact head 19. Under the elastic force generated by the spring 20's recovery deformation, the impact head 19 can be driven upwards, precisely striking the bottom of the stamping seat 2. This generates a vibration effect, effectively breaking the adhesion between the stamped steel plate and the inner wall of the stamping groove 5 at the top of the stamping seat 2. This allows the steel plate to separate smoothly from the inner wall of the stamping groove 5, greatly simplifying the demolding process and improving operational convenience and efficiency. The assembly sleeve 14 and plug 15 facilitate further... The stamping head 3 can be easily replaced by the mounting groove 11 and mounting strip 17, which facilitates the replacement of the stamping seat 2. This allows for the stamping of steel plates required for automotive crossbeams of different sizes, enhancing the device's versatility. By adjusting the size, shape, and layout of the stamping groove 5 on the top of the stamping seat 2 and the stamping head 3, the device can flexibly adapt to various specifications of automotive crossbeam steel plates, ensuring that every stamping operation meets the precision requirements. Whether the automotive crossbeam steel plates are large or small, or have special shapes, the device can easily handle them, providing automotive manufacturers with an efficient and reliable stamping solution.
