The stamping die for processing automotive sheet metal parts involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1 to 8This utility model provides a stamping die for processing automotive sheet metal parts, including a main body 1, and further including: a pusher mechanism 2, a rotating mechanism 3, a lower die mechanism 4, and an upper die mechanism 5. The top end of the main body 1 is movably connected to the bottom end of the rotating mechanism 3, the bottom end of the lower die mechanism 4 is fixedly connected to the top end of the rotating mechanism 3, the top end of the upper die mechanism 5 is fixedly connected to the bottom end of the main body 1, and the side of the pusher mechanism 2 is movably connected to the inner side wall of the lower die mechanism 4. The main body 1 includes a machine body 101, which has a placement groove 105. The rotating mechanism 3 includes a rotating table 301. The side of the platform 301 is movably connected to the side of the placement slot 105. A gantry frame 103 is fixedly connected to the top of the machine body 101, and a hydraulic telescopic rod 104 is fixedly connected to the top of the gantry frame 103. The bottom end of the hydraulic telescopic rod 104 is fixedly connected to the top of the upper mold mechanism 5. The lower mold mechanism 4 includes a lower mold body 401, the bottom end of which is fixedly connected to the top of the rotary table 301. A through slot 403 is provided on the side of the lower mold body 401, and a cavity 404 is provided inside the lower mold body 401. The pushing mechanism 2 includes a rotating rod 201, the side of which is connected to the through slot 403. The side of the 03 is movably connected by a pin. The side of the rotating rod 201 is movably connected to a connecting frame 208. The top of the lower mold body 401 has a cavity 402. The bottom of the cavity 402 has a placement hole 405. The bottom of the placement hole 405 has a through hole 406. The side of the placement hole 405 is movably connected to a push block 203. The bottom of the push block 203 is fixedly connected to a limit rod 210. The bottom of the limit rod 210 is fixedly connected to the connecting frame 208. The side of the connecting frame 208 is movably connected to the side of the rotating rod 201. The top of the push block 203 is flush with the bottom of the cavity 402. The metal material is placed inside the chamber 402. The rotary table 301 rotates, causing the lower die mechanism 4 to move directly below the upper die mechanism 5. The hydraulic telescopic rod 104 pushes the upper die mechanism 5 downward, so that the upper die mechanism 5 and the lower die mechanism 4 cooperate to stamp the sheet metal material. The stamped sheet metal part moves away from below the upper die mechanism 5 as the rotary table 301 rotates and moves to the working position. Pressing down the rotating rod 201 causes the rotating rod 201 to rotate along the side pin of the through groove 403, thereby pushing the limit rod 210 upward through the connecting frame 208, so that the push block 203 pushes the sheet metal part out of the chamber 402 for easy removal.

[0026] The top of the cavity 404 is fixedly connected to a pressure spring 207, and the side of the limiting rod 210 is fixedly sleeved with an installation ring 209. The top of the installation ring 209 is fixedly connected to the bottom of the pressure spring 207. The pressure spring 207 pushes the installation ring 209 downward to make the push block 203 retract into the placement hole 405, so that the inside of the cavity 402 remains flat.

[0027] The connecting frame 208 has a movable column 212 movably sleeved on its side. The rotating rod 201 has a movable groove 211 on its side corresponding to the position of the movable column 212. The side of the movable groove 211 is movably connected to the side of the movable column 212. When the rotating rod 201 rotates, the movable groove 211 locks the movable column 212 and drives the movable column 212 to move upward. At the same time, the movable column 212 slides laterally along the movable groove 211, converting the circular motion of the rotating rod 201 into the vertical linear motion of the connecting frame 208.

[0028] The top of the rotating rod 201 is movably connected to a roller 206 via a pin. The top of the machine body 101 is fixedly connected to a mounting block 202 corresponding to the position of the roller 206. A pressure block 205 is fixedly connected to the side of the mounting block 202. The bottom end of the pressure block 205 has an inclined surface 204. During the processing, the rotary table 301 rotates clockwise. The stamped sheet metal part rotates to the position of the mounting block 202 along with the rotary table 301. The roller 206 contacts the inclined surface 204 and rolls along the inclined surface 204, thereby causing the rotating rod 201 to rotate downward along the pin on the side of the through groove 403.

[0029] The equipment includes four lower die mechanisms 4, which are evenly distributed on the top of the rotary table 301. The bottom of the placement slot 105 is provided with a first mounting slot 102, and a servo motor 303 is fixedly connected to the bottom of the first mounting slot 102. The output shaft of the servo motor 303 is fixedly connected to the bottom of the rotary table 301. When the equipment is in operation, the operator stands in front of the equipment to pick up and place the sheet metal parts. Then, the servo motor 303 drives the rotary table 301 to rotate clockwise, so that the lower die mechanisms 4 rotate in sequence to be directly below the upper die mechanism 5 for stamping processing, thereby realizing the simultaneous stamping and sheet metal part picking to improve work efficiency.

[0030] The bottom end of the placement groove 105 is provided with a second mounting groove 106. The side of the second mounting groove 106 is movably sleeved with a support wheel 302 by a pin. The top end of the support wheel 302 is connected to the bottom end of the rotary table 301. When the rotary table 301 rotates, the support wheel 302 supports the rotary table 301 and rolls along the bottom of the rotary table 301. The friction at the contact point reduces wear.

[0031] The working principle of this utility model is as follows: The operator stands in front of the equipment and places the sheet metal material to be processed into the chamber 402. The servo motor 303 is started, driving the rotary table 301 to rotate clockwise, moving the next lower die mechanism 4 to the appropriate front position. The stamped sheet metal part is removed and a new sheet metal material is placed in. This process is repeated until the sheet metal material on the lower die mechanism 4 moves directly below the upper die mechanism 5. The hydraulic telescopic rod 104 is activated to push the upper die mechanism 5 downwards, allowing the upper die mechanism 5 and the lower die mechanism 4 to cooperate in stamping the sheet metal material. After stamping, the placement groove 105 moves the upper die mechanism 5 upwards, separating it from the lower die mechanism 4. The sheet metal part on the lower die mechanism 4... As the rotary table 301 rotates to the position of the mounting block 202, the roller 206 contacts the inclined surface 204 and rolls along the inclined surface 204, thereby causing the rotating rod 201 to rotate downward along the pin on the side of the through groove 403. The movable groove 211 locks the movable column 212 and drives the movable column 212 to move upward. At the same time, the movable column 212 slides laterally along the movable groove 211, thereby causing the connecting frame 208 to push the limiting rod 210 upward, causing the push block 203 to push the sheet metal part out of the chamber 402. After the roller 206 passes the inclined surface 204, the pressure spring 207 pushes the mounting ring 209 downward, causing the push block 203 to be retracted into the placement hole 405, keeping the inside of the chamber 402 flat.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
