Description

Technical Field

[0001] This utility model relates to the field of stamping technology for automobile shells, and more specifically to a stamping device for automobile shells. Background Technology

[0002] The manufacturing process of automobile bodies requires a large number of stamped parts, which play a supporting and connecting role within the vehicle. The car body shell, in particular, not only needs precise structural design to support and connect core components such as the engine, chassis, and electrical systems, but also needs a curved structure to reduce air resistance during driving and the instantaneous impact force during a collision. This allows it to maximize the protection of the passenger compartment's integrity through crumple zones in the event of an accident. Functionally, the car body shell must also provide aesthetics and decoration to meet the personalized needs of drivers regarding the vehicle's appearance. Stamping is frequently used in the manufacturing process of car body shells. By selecting appropriate composite dies and assembling them on hydraulic stamping equipment, and placing sheet metal within the die's cavity, the sheet metal is directly subjected to deformation forces and deformed within the die using the power of conventional or specialized stamping equipment to quickly create the required shell shape. By changing the dies, different shapes can be stamped to obtain shell components of various shapes, sizes, and performance characteristics. It is precisely because of the high efficiency and flexibility of stamping that stamping equipment is widely used in the manufacturing process of automobile body shells.

[0003] To improve the efficiency of stamping loading and unloading and reduce manufacturing risks, a negative pressure suction cup transfer mechanism is used to automate the stamping loading and unloading tasks. This mechanism works by using an air pump to create a negative pressure environment for the suction cups, allowing them to firmly adhere to the sheet metal and the outer shell. Subsequently, driven by a motor, the suction cups can be precisely moved to the designated position, achieving efficient loading and unloading operations. However, to reduce air resistance during driving and ensure the smooth lines of the car's exterior, the car body needs to be designed with a curved structure. Furthermore, to facilitate the installation of electrical systems and other components on the outer shell, a series of through holes need to be stamped. However, negative pressure suction cups have difficulty adhering to curved surfaces, and if the suction cup covers the through holes of the outer shell, it will not be able to effectively adhere to the shell, preventing the suction cup transfer mechanism from smoothly removing the shell from the stamping equipment. Therefore, improvements are needed in the stamping blanking process for the car body to facilitate the removal of the stamped shell from the stamping equipment, allowing for repeated blanking operations and significantly improving stamping efficiency and stability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a stamping device for automobile shells that facilitates the removal of stamped shells and allows for repeated blanking operations, thereby overcoming the deficiencies in existing technologies.

[0005] The technical solution adopted by this utility model is as follows: a stamping equipment for automobile shells, including a base, a hydraulic cylinder mounted on the base, and a pressure plate mounted on the hydraulic cylinder. The top of the base is respectively provided with a hinge, a fixed frame, and a lower die base. One end of the fixed frame is hinged to the base via a hinge. The lower die base is fitted inside the fixed frame and mounted on the base. The pressure plate is respectively provided with a support frame and an upper die base. Both the upper die base and the support frame are mounted on the bottom surface of the pressure plate. The upper die base is fitted inside the support frame, and a locking mechanism is provided on the support frame. The locking mechanism... The structure includes a support block located on the side of the support frame away from the hinge. The support block is equipped with a locking block and a spring. The top of the support block is mounted on the outer wall of the support frame, and a rectangular support groove is formed at the bottom of the support block. One side of the spring and the locking block are located in the support groove. The cross-sectional shape of the locking block matches the cross-sectional shape of the support groove. The two ends of the spring are connected to the locking block and the support block, respectively. An inclined groove is formed on the other side of the locking block. The height of the inclined groove gradually increases along the direction close to the upper mold base. The other side of the locking block is located above the fixed frame.

[0006] Preferably, a buffer groove is provided on the side of the base away from the hinge. The buffer groove is located at the top of the base. A second spring is provided in the buffer groove. A support rod is provided above the second spring. The support rod is fitted into the buffer groove. A buffer pad made of elastic material is provided above the support rod. The buffer pad is installed on the top of the support rod. The top of the buffer pad is in contact with the fixed frame.

[0007] Preferably, a guide plate is inclinedly provided on the side of the fixed frame away from the lower mold base. The guide plate is installed on the lower mold base and gradually decreases in the direction away from the lower mold base. A baffle is provided at the end of the guide plate away from the lower mold base. The bottom end of the baffle is installed on the guide plate. A push groove is opened on the side of the guide plate near the baffle. A push plate is provided in the push groove. A cylinder is provided below the push plate. The telescopic end of the cylinder is connected to the push plate. The cylinder is installed on the guide plate.

[0008] Preferably, the guide plate is inclined with an L-shaped fixing plate on the side away from the fixing frame. The fixing plate gradually decreases along the side away from the lower mold base. The end of the horizontal plate of the fixing plate away from the vertical plate of the fixing plate is installed on the top of the baffle. A bracket is provided between the fixing plate and the machine base. The two sides of the bracket are respectively installed on the fixing plate and the machine base.

[0009] Preferably, the guide plate has a sleeve hole in the middle, which is connected to the push groove. The telescopic rod of the cylinder is fitted into the sleeve hole, and the cylinder is installed on the bottom surface of the guide plate. The guide plate has through holes on both sides, which are connected to the push groove. A fixing rod is fitted into the through hole and installed on the bottom surface of the push plate. The diameter of the fixing rod matches the diameter of the through hole. A fixing sleeve is fitted onto the fixing rod and installed on the bottom surface of the guide plate. The inner diameter of the fixing sleeve matches the diameter of the fixing rod.

[0010] Preferably, the base below the support block has a fixing groove, the support groove extends from the end of the support block near the upper mold base to the outer side of the support block, and the inner wall of the fixing frame has a guide groove, the width of the guide groove gradually increases in the direction away from the lower mold base.

[0011] The beneficial effects of this utility model are as follows: First, by using a hydraulic cylinder, this utility model controls the up-and-down movement of the pressure plate, support frame, upper mold base, support block, locking block, and spring 1. This series of movements causes the upper mold base to stamp the sheet metal placed on the lower mold base, while the support frame presses the edges of the sheet metal placed on the fixed frame, thereby processing the sheet metal into a shell. Furthermore, this utility model guides the movement of the locking block using an inclined groove and utilizes the compression action of spring 1 to move the locking block below the fixed frame. This allows the locking block to lift the fixed frame and rotate it around the hinge, thereby causing the stamped shell to rotate. As the angle of inclination of the stamped shell gradually increases, the stamped shell slides off the fixed frame, allowing it to be removed from the machine base. In addition, after the outer casing is removed, the locking block will continue to move upward as the hydraulic cylinder extends. As the locking block moves upward, it will slide out from the side of the fixed frame away from the hinge. At this time, the fixed frame will fall onto the machine base because it loses the support of the locking block, so as to reset the fixed frame and facilitate repeated stamping of the sheet metal.

[0012] Secondly, this invention uses a spring, support rod, and buffer pad to cushion the falling fixed frame, reducing the impact on the fixed ring and base, thereby improving the stability of the fixed frame. A guide plate guides the outer casing sliding out of the fixed frame, and a baffle blocks the conveyed outer casing, preventing it from falling directly to the ground. Furthermore, the invention uses a cylinder and push plate to lift the outer casing blocked by the baffle, allowing it to slide out from above the baffle, thus controlling the conveying of the outer casing.

[0013] Furthermore, this invention utilizes an L-shaped fixing plate to temporarily store the outer casing transported by the guide plate, facilitating its removal. A bracket further supports the guide plate and fixing plate, enhancing their stability. Additionally, a fixing rod and a fixing sleeve restrict the movement direction of the push plate, reducing wobbling during movement and improving its stability. Moreover, a fixing groove on the base prevents the support block and locking block from colliding with the base, and a guide groove on the fixing frame prevents collisions between the fixing frame and the lower mold base during descent.

[0022] like Figures 1 to 8As shown, a stamping device for an automobile body includes a base 1, a hydraulic cylinder 2 mounted on the base 1, and a pressure plate 3 mounted on the hydraulic cylinder 2. The top of the base 1 is respectively provided with a hinge 4, a fixing frame 5, and a lower die base 6. One end of the fixing frame 5 is hinged to the base 1 via the hinge 4. The lower die base 6 is located inside the fixing frame 5 and is mounted on the base 1. The pressure plate 3 is respectively provided with a support frame 7 and an upper die base 8. Both the upper die base 8 and the support frame 7 are mounted on the bottom surface of the pressure plate 3. The upper die base 8 is located inside the support frame 7, and a locking mechanism is provided on the support frame 7. The locking mechanism includes the support frame 7 being located away from the hinge 4. A support block 9 is provided on one side, and each support block 9 is equipped with a locking block 10 and a spring 11. The top of the support block 9 is mounted on the outer wall of the support frame 7, and the bottom of the support block 9 has a rectangular support groove 12. One side of the spring 11 and the locking block 10 are located in the support groove 12. The cross-sectional shape of the locking block 10 matches the cross-sectional shape of the support groove 12. The two ends of the spring 11 are connected to the locking block 10 and the support block 9, respectively. An inclined groove 13 is provided on the other side of the locking block 10. The height of the inclined groove 13 gradually increases along the direction close to the upper mold base 8. The other side of the locking block 10 is located above the fixed frame 5. By controlling the hydraulic cylinder 2 to retract, the upper mold base 8 is driven to stamp the sheet metal placed on the lower mold base 6, and the support frame 7 and the fixed frame 5 are used to squeeze the edge of the sheet metal. At the same time, the inclined groove 13 guides the locking block 10 to move below the fixed frame 5 under the squeezing action of the spring 11. Subsequently, after the sheet metal is stamped to form a shell, the hydraulic cylinder 2 is extended, causing the upper mold base 8 and the support frame 7 to rise. This causes the locking block 10 to pull the fixed frame 5 to rotate around the hinge 4, thereby causing the stamped shell to rotate. As the angle of the stamped shell gradually increases, the stamped shell will slide off the fixed frame 5 so that it can be removed from the machine base 1. Then, as the locking block 10 continues to move upward, it will slide off the side of the fixed frame 5 away from the hinge 4. The fixed frame 5 will then fall onto the machine base 1 due to the loss of the support of the locking block 10, so that the sheet metal can be stamped again.

[0023] In this embodiment, a buffer groove 14 is provided on the side of the base 1 away from the hinge 4. The buffer groove 14 is located on the top of the base 1. A second spring 15 is provided in the buffer groove 14. A support rod 16 is provided above the second spring 15. The two ends of the second spring 15 are connected to the bottom end of the buffer groove 14 and the bottom end of the support rod 16, respectively. The support rod 16 is fitted into the buffer groove 14. A buffer pad 17 made of elastic material is provided above the support rod 16. The buffer pad 17 is installed on the top end of the support rod 16. The top end of the buffer pad 17 is in contact with the fixed frame 5. Thus, the second spring 15 and the buffer pad 17 are used to buffer the fall of the fixed frame 5, thereby improving the stability of the fixed frame 5.

[0024] Please refer to it again. Figure 1 , 3 In section 8, a guide plate 18 is inclinedly arranged on the side of the fixed frame 5 away from the lower mold base 6. The guide plate 18 is installed on the lower mold base 6 and gradually decreases in the direction away from the lower mold base 6, so that the shell sliding out from the fixed frame 5 is conveyed through the guide plate 18. A baffle 19 is provided at the end of the guide plate 18 away from the lower mold base 6. The bottom end of the baffle 19 is installed on the guide plate 18, thereby blocking the shell conveyed on the guide plate 18 and preventing the shell from sliding directly to the ground. A push groove 20 is opened on the side of the guide plate 18 near the baffle 19. A push plate 21 is provided in the push groove 20. A cylinder 22 is provided below the push plate 21. The telescopic end of the cylinder 22 is connected to the push plate 21. The cylinder 22 is installed on the guide plate 18. By controlling the extension of the cylinder 22, the push plate 21 is driven to rise, thereby driving the shell above the push plate 21 to rise. When the shell is higher than the baffle 19, the shell will slide out along the push plate 21 to control the conveying of the shell.

[0025] Specifically, an L-shaped fixing plate 23 is inclinedly arranged on the side of the guide plate 18 away from the fixing frame 5. The fixing plate 23 gradually decreases along the side away from the lower mold base 6. The end of the horizontal plate of the fixing plate 23 away from the vertical plate of the fixing plate 23 is installed on the top of the baffle 19, thereby temporarily storing the outer shell transported out by the guide plate 18 so that the outer shell can be taken out. A bracket 24 is provided between the fixing plate 23 and the machine base 1. The two sides of the bracket 24 are respectively installed on the fixing plate 23 and the machine base 1, thereby supporting the guide plate 18 and the fixing plate 23 and improving the firmness of the guide plate 18 and the fixing plate 23.

[0026] In this embodiment, a sleeve hole is provided in the middle of the guide plate 18, which is connected to the push groove 20. The telescopic rod of the cylinder 22 is fitted into the sleeve hole. The cylinder 22 is installed on the bottom surface of the guide plate 18, so as to facilitate the use of the cylinder 22 to push the push plate 21 upward. Through holes are provided on both sides of the guide plate 18, which are connected to the push groove 20. A fixing rod 25 is fitted into the through hole. The fixing rod 25 is installed on the bottom surface of the push plate 21. The diameter of the fixing rod 25 matches the diameter of the through hole. A fixing sleeve 26 is fitted on the fixing rod 25. The fixing sleeve 26 is installed on the bottom surface of the guide plate 18. The inner diameter of the fixing sleeve 26 matches the diameter of the fixing rod 25 to constrain the fixing rod 25, thereby limiting the movement direction of the push plate 21, reducing the shaking that occurs during the movement of the push plate 21, and thus improving the stability of the push plate 21 in use.

[0027] Please refer to it again. Figure 3 , 5In section 7, the base 1 below the support block 9 is provided with a fixing groove 27. The fixing groove 27 is located below the fixing frame 5. The support block 9 and the locking block 10 can both be inserted into the fixing groove 27 as the hydraulic cylinder 2 retracts, so as to avoid the support block 9 and the locking block 10 colliding with the base 1. The support groove 12 is opened along the end of the support block 9 near the upper mold base 8 to the outside of the support block 9, so that when the locking block 10 is pressed, the other side of the locking block 10 is pressed into the support groove 12. The inner wall of the fixing frame 5 is provided with a guide groove 28. The width of the guide groove 28 gradually increases in the direction away from the lower mold base 6, so as to avoid the fixing frame 5 colliding with the lower mold base 6 during the falling process.

[0028] The instructions for using this product are as follows: Figures 1 to 8 As shown, firstly, the hydraulic cylinder 2 is extended to move the pressure plate 3 and the upper mold base 8 away from the machine base 1. After the hydraulic cylinder 2 extends, the suction cup transfer mechanism is used to place the sheet metal onto the lower mold base 6. After the sheet metal is placed, the suction cup transfer mechanism is moved out from between the lower mold base 6 and the upper mold base 8 to avoid collision between the suction cup transfer mechanism and the product, which could cause damage. Then, the hydraulic cylinder 2 is shortened, so that the upper mold base 8 stamps the sheet metal placed on the lower mold base 6, and the support frame 7 presses the edge of the sheet metal placed on the fixed frame 5 to process the sheet metal into a shell. At the same time, the inclined groove 13 on the locking block 10 guides the movement of the locking block 10, and the spring 11 presses the locking block 10 from above the fixed frame 5 into the fixed groove 27. After the stamping operation is completed, the hydraulic cylinder 2 is extended, which moves the upper die holder 8, support block 9, and locking block 10 upward, effectively separating the upper die holder 8 from the stamped shell. The locking block 10 then lifts the fixing frame 5 to rotate around the hinge 4, causing the stamped shell to rotate and slide down from the fixing frame 5 onto the guide plate 18 along an inclined direction. The locking block 10 continues to move upward as the hydraulic cylinder 3 extends, sliding out from the side of the fixing frame 5 away from the hinge 4. The fixing frame 5, now unsupported by the locking block 10, falls onto the buffer pad 17, allowing it to reset and facilitating repeated stamping of the sheet metal. Finally, the cylinder 22 is extended to transport the stamped shell onto the fixing plate 23 via the push plate 21, making it easy to remove the stamped shell.

[0029] In this embodiment, the hydraulic cylinder 2 controls the up-and-down movement of the pressure plate 3, support frame 7, upper mold base 8, support block 9, locking block 10, and spring 11. This series of movements causes the upper mold base 8 to stamp the sheet metal placed on the lower mold base 6, while the support frame 7 presses the edge of the sheet metal placed on the fixed frame 5, thereby processing the sheet metal into a shell. Furthermore, in this embodiment, the movement of the locking block 10 is guided by the inclined groove 13 on the locking block 10, and the pressing action of the spring 11 causes the locking block 10 to move below the fixed frame 5. The locking block 10 then lifts the fixed frame 5 to rotate around the hinge 4, thereby causing the stamped shell to rotate. As the angle of inclination of the stamped shell gradually increases, the stamped shell will slide off the fixed frame 5, allowing it to be removed from the machine base 1. In addition, after the outer casing is removed, the locking block 10 will continue to move upward as the hydraulic cylinder 3 extends. As the locking block 10 moves upward, it will slide out from the side of the fixed frame 5 away from the hinge 4. At this time, the fixed frame 5 will fall on the machine base 1 because it loses the support of the locking block 10, so as to reset the fixed frame 5 and facilitate repeated stamping of the sheet metal.
