Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping device for automobile door sill plates. Background Technology

[0002] The sill plate is a crucial component of the car sill structure, typically located inside the sill reinforcement or between the outer and inner sill plates. Its primary functions include load-bearing, impact energy absorption, and support. It allows for more rational load transfer and more even load distribution within the sill and its internal structure, effectively improving the sill's load-bearing capacity. In the event of a side impact, it helps absorb and disperse impact forces, protecting occupants and components such as the battery pack. Car sill plates are usually manufactured using a stamping process, typically employing high-strength thin steel sheets as raw materials. Pressure is applied through a stamping press, causing the sheet material to plastically deform in a mold, thus forming a sill plate with a specific shape, size, and structure. This part is often U-shaped, and may have multiple mounting holes on the bottom and sides.

[0003] For example, in the prior art, there is a stamping device for automobile door sill plates with the prior art publication number CN219851590U. In this prior art, the processed automobile door sill plates are automatically ejected and unloaded, and are stably conveyed out by a conveyor belt. The fixed mold and the moving mold are connected by a positioning rod and a positioning hole, and the placement groove positions and loads the raw material, ensuring the accuracy of the stamping process and ensuring stable stamping of the raw material, resulting in a high yield of automobile door sill plates.

[0004] The existing technology has the following problems in practical use: During the descent of the car door sill plate, it will directly collide with the conveyor belt, easily causing deformation. Furthermore, due to the elasticity of the conveyor belt, the part is also at risk of falling off. These problems not only lead to component damage but also directly affect the quality and efficiency of stamping. Utility Model Content

[0016] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0017] Please see Figures 1-5This utility model provides a stamping device for automobile door sill plates, including a stamping base 1. The stamping base 1 has a stamping male head 2 and a stamping female head 3 fixedly arranged on the top of the stamping base 1, which are used to stamp automobile door sill plates. A groove 4 is opened on the rear side of the top of the stamping base 1. A belt conveyor 5 is fixedly installed inside the groove 4. The belt conveyor 5 is a continuous operation transportation device that uses a conveyor belt as a traction and load-bearing component. The motor in the drive device drives the drive drum to rotate through the reducer. The friction between the drive drum and the conveyor belt generates a friction force, so that the conveyor belt wraps around the drive drum and the redirecting drum to form an endless loop belt and moves continuously. The formed automobile door sill plate slides onto the conveyor belt and is transported to the unloading point by the friction between it and the conveyor belt.

[0018] The belt conveyor 5 is fixedly provided with a support plate 6 on top, and a linear module 7 is fixedly embedded on the top of the support plate 6. A pad 8 is fixedly provided on the top of the linear module 7, and a buffer plate 9 is provided on the top of the pad 8. The linear module 7 is an automated transmission element that uses an electric motor to provide power and converts rotary motion into linear motion through transmission mechanisms such as ball screws, synchronous belts, or gear racks. It is precisely guided by linear guides and achieves closed-loop control with the help of encoder feedback. Finally, it completes a high-precision and highly repeatable linear positioning task under the program instructions.

[0019] like Figure 3 and Figure 4 As shown, the buffer plate 9 includes a base plate 91, and a rubber pad 92 is fixedly provided on the top of the base plate 91.

[0020] The buffer plate 9 is connected to the pad plate 8 via a rotating assembly 10. The rotating assembly 10 includes a rotating rod 101 rotatably mounted on one side of the pad plate 8. A semi-circular groove 102 is provided on one side of the base plate 91. The rotating rod 101 is fixed inside the semi-circular groove 102. A fixing groove 103 is provided at the rear end of the pad plate 8. A motor 104 is fixed inside the fixing groove 103. The front end of the output shaft of the motor 104 passes through the pad plate 8 and is fixed to the rear end of the rotating rod 101. The motor 104 can be an electromagnetic brake servo motor. When the power is off, the shaft is locked, so that the base plate 91 can be kept in an inclined state for easy and rapid unloading.

[0021] A fixing block 16 is fixedly provided on one side of the top of the stamping base 1. A second electric push rod 17 is fixedly passed through the inside of the fixing block 16. The piston rod of the second electric push rod 17 is fixed to the stamping male head 2.

[0022] In actual production, a robotic arm is used to automate the feeding process. Then, the second electric push rod 17 drives the stamping male head 2 to move horizontally, working in conjunction with the stamping female head 3 to complete the stamping of the car door sill plate. The formed door sill plate is then removed from the stamping female head 3 by the robotic arm and placed on a buffer plate 9. This buffer plate 9 consists of a base plate 91 and a rubber pad 92. The softness of the rubber material effectively mitigates the impact on the bottom of the formed door sill plate. Subsequently, the linear module 7 moves the pad 8 backwards above the belt conveyor 5. The motor 104 on the pad 8 drives the rotating rod 101 to rotate the base plate 91, causing it to tilt. The formed door sill plate slides down along the rubber pad 92 onto the belt conveyor 5, achieving automatic conveying.

[0023] like Figures 1-4 As shown, a mounting block 11 is fixedly provided on the side of the base plate 91 away from the rotating rod 101. A first electric push rod 12 is fixedly provided on the top of the mounting block 11. A push plate 13 is fixedly provided at one end of the piston rod of the first electric push rod 12. The push plate 13 is located above the rubber pad 92. In addition, two symmetrically distributed sliders 14 are fixedly provided at the bottom of the pad plate 8. A groove 15 adapted to the sliders 14 is opened on the top of the support plate 6. The sliders 14 are located inside the groove 15.

[0024] The push plate 13 is driven to move to the right by the first electric push rod 12. The push plate 13 can accelerate the sliding speed of the formed door sill partition, thereby further improving the production efficiency of the car door sill partition.

[0025] Both the first electric actuator 12 and the second electric actuator 17 can be electric actuators equipped with servo motors and ball screws, which can achieve wide-range speed adjustment. The ball screw at the end can efficiently convert rotary motion into linear displacement, while achieving precise length adjustment.

[0026] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
