Technical Field

[0001] This utility model relates to the field of combined stamping and bending technology, specifically a device for facilitating the flanging and bending of bottom guard plates. Background Technology

[0002] During car manufacturing, a skid plate is installed under the chassis. This skid plate is typically made of a high-hardness alloy, and its top surface must conform to the shape of the car's underbody components to ensure a tighter fit. Additionally, some skid plates have side panels, primarily for protecting internal car parts and preventing mud and water from entering and damaging them.

[0003] The manufacturing of bottom guard plates typically employs a pressure-pressing molding technique, where a sheet of material is pressed down to form the desired shape. During pressing, the user needs to precisely position the bottom guard plate to ensure its dimensions are standardized, resulting in a more aesthetically pleasing finish. After pressure pressing and molding, the user needs to bend the edges of the bottom guard plate to form the side guards. However, traditionally, stamping and bending are performed separately, requiring multiple positioning checks during the bottom guard plate manufacturing process. Even with positioning mechanisms, there is still a certain margin of error between the two positioning checks, affecting the overall accuracy of the bottom plate structure. Furthermore, these multiple positioning checks complicate the manufacturing process. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] In this embodiment, referring to 1-5, a device for facilitating the flanging and bending of the bottom guard plate includes a pressure mechanism 1. A lower die 104 is installed inside the pressure mechanism 1. The lower die 104 is stably installed and serves as a reference support component for the stamping process of the bottom guard plate, providing a stable processing platform for the stamping process. An upper die 103 is provided directly above the lower die 104. The upper die 103 and the lower die 104 cooperate with each other to complete the stamping and forming of the bottom guard plate. The bending and rotating plate 3, the lower die 104 has mounting blocks 301 symmetrically fixedly connected to the outer surface of the lower die 104, and the bending and rotating plate 3 is rotatably connected between the mounting blocks 301; The movable rod 307 is installed below the bending and rotating plate 3, and the movable rod 307 is internally threaded with a ball screw 310.

[0018] The bottom of the bending and rotating plate 3 is provided with a groove 304, and a moving block 305 is slidably connected inside the groove 304. The groove 304 adopts a through groove design and its cross-sectional shape is T-shaped, which can prevent the moving block 305 from falling out of the groove 304. The bottom of the moving block 305 is rotatably connected to a connecting block 306. The bottom of the connecting block 306 is fixedly connected to the top of the moving rod 307. The connection between the bottom of the moving block 305 and the connecting block 306 is a ball joint connection, which allows the moving rod 307 to adapt to the angle change of the bending and rotating plate 3 during the process of pushing the bending and rotating plate 3 to rotate, ensuring power transmission while avoiding jamming.

[0019] A sleeve rod 309 is fixedly connected inside the pressure mechanism 1 at a position corresponding to the bending and rotating plate 3. The inner wall of the sleeve rod 309 is precision machined with low surface roughness, which reduces the frictional resistance when the moving rod 307 slides. The inside of the sleeve rod 309 is slidably connected to the moving rod 307. A control panel 4 is fixedly connected to the outer surface of the pressure mechanism 1. The control panel 4 is used to control the rotation of two sets of servo motors 312. The control panel 4 can control the rotation angle of the bending and rotating plate 3 by controlling the number of rotations of the servo motors 312, thereby controlling the angle of the bottom guard plate flange.

[0020] An mounting plate 308 is fixedly connected to the inner wall of the pressurizing mechanism 1. The mounting plate 308 is fastened to the inner wall of the pressurizing mechanism 1 by bolts, and its surface is kept horizontal. A servo motor 312 is fixedly connected to the top of the mounting plate 308. The servo motor 312 can drive the moving rod 307 to move. The moving rod 307 is square, which can limit its rotational movement inside the sleeve rod 309. The output end of the servo motor 312 passes through the sleeve rod 309 and its end face is fixedly connected to the bottom outer surface of the ball screw 310. The end face of the output end of the servo motor 312 is fixedly connected to the bottom outer surface of the ball screw 310 through a coupling. The coupling can compensate for the coaxiality error between the output shaft of the ball screw 310 and the servo motor 312, and reduce vibration and noise.

[0021] The inner wall of the pressurizing mechanism 1 is fixedly connected with support frames 311 at even intervals. The support frames 311 are fixedly connected to the outer surface of the sleeve rod 309. The support frames 311 are made of angle steel, with one end welded to the outer surface of the sleeve rod 309 and the other end fastened to the inner wall of the pressurizing mechanism 1 by bolts.

[0022] One side of the bending and rotating plate 3 passes through the mounting block 301 and is fixedly connected to the end face of the rotating pointer disk 303. When the bending and rotating plate 3 rotates, it will rotate in conjunction with the rotating pointer disk 303. The rotating pointer disk 303 is provided with scale lines 302 around its perimeter. The scale lines 302 are opened on the surface of the mounting block 301. The rotating pointer disk 303 can read the rotation angle through the scale lines 302, and thus estimate the angle of the bottom guard plate flange.

[0023] Four sets of sliding rods 101 are fixedly connected to the inner wall of the pressurizing mechanism 1. To ensure the stability and accuracy of the upper mold 103 during the pressing and closing process, four sets of sliding rods 101 are fixedly connected to the inner wall of the pressurizing mechanism 1. The four sets of sliding rods 101 pass through the moving plate 102. When the pressing and closing process is started, the moving plate 102 can slide smoothly along the sliding rods 101, thereby driving the upper mold 103 to achieve the pressing and closing action. The bottom of the moving plate 102 is fixedly connected to the upper mold 103 through a connecting piece. The connecting piece adopts a combination of bolts and positioning pins, which ensures the connection. To ensure stability and prevent the upper mold 103 from shifting during operation, the bottom of the moving plate 102 is symmetrically fixed with stabilizing rods 2, and a stabilizing column 201 is set directly below the stabilizing rods 2. When the moving plate 102 drives the upper mold 103 to move downward for stamping, the stabilizing rods 2 will be precisely inserted into the stabilizing column 201. The stabilizing columns 201 are installed on both sides of the lower mold 104. The stabilizing columns 201 and the stabilizing rods 2 can improve the accuracy of the mold closing between the upper mold 103 and the lower mold 104, and can prevent mold shifting caused by excessive stamping pressure or uneven force.

[0024] The pressurizing mechanism 1 is equipped with a pressurizing drive mechanism 106, which is hydraulically driven. Its output end is fixedly connected to the upper outer surface of the upper die 103 via a flange or other structure. The output end of the pressurizing drive mechanism 106 is fixedly connected to the upper outer surface of the upper die 103. A support column 105 is fixedly connected inside the pressurizing mechanism 1 directly below the lower die 104. The support column 105 is made of high-strength alloy material and can withstand the pressure transmitted to the lower die 104 during the stamping process, preventing the lower die 104 from sinking due to force and affecting the processing accuracy. A sealing door 202 is rotatably connected to the inner wall of the pressurizing mechanism 1. The sealing door 202 is used to seal and protect the internal parts of the pressurizing mechanism 1. During maintenance, the sealing door 202 can be opened to directly view and repair the relevant parts.

[0025] This utility model provides a device for easily bending and folding the bottom guard plate, and its specific working principle is as follows: During processing, the user adjusts the position of the raw material of the bottom guard plate and places it above the lower mold 104. Then, the user starts the pressure drive mechanism 106, which drives the moving plate 102 to slide down along the slide bar 101, causing the upper mold 103 to move down synchronously. When the upper mold 103 and the lower mold 104 are close, the stabilizing rod 2 at the bottom of the moving plate 102 will gradually insert into the stabilizing columns 201 on both sides of the lower mold 104, so as to achieve precise positioning of the upper mold 103 and the lower mold 104. When the upper mold 103 and the lower mold 104 are completely closed, the molding process of the bottom guard plate will be completed.

[0026] After the pressurization process is completed, keep the position of the upper mold 103, start the servo motor 312, drive the ball screw 310 to rotate, and make the moving rod 307 slide upward along the sleeve rod 309. During the upward movement of the moving rod 307, the bottom moving block 305 pushes the bending rotating plate 3 to rotate around the mounting block 301. The user can adjust the rotation angle of the bending rotating plate 3 by adjusting the number of rotations of the servo motor 312, thereby achieving the purpose of bending the two sides of the bottom guard plate. After bending, the bending rotating plate 3 remains stationary, thereby reducing the rebound angle of the bottom guard plate. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
