Description

Technical Field

[0001] This utility model belongs to the field of stamping equipment technology, specifically relating to metal stamping equipment with automatic feeding function. Background Technology

[0002] In the metal processing industry, stamping equipment uses dies to perform pressure processing on metal sheets and profiles, and is widely used in industries such as automobile manufacturing, home appliance production, and hardware processing. With the development of automation technology, stamping equipment with automatic feeding functions is gradually replacing manual feeding equipment, becoming an important means to improve production efficiency and reduce labor costs.

[0003] However, traditional feeding mechanisms mostly adopt a unidirectional pushing structure. During the conveying process, metal materials are prone to deviation due to inertia or uneven friction, resulting in positional deviation when the material enters the mold slot, affecting stamping accuracy, and even causing scrap. The linkage between the feeding mechanism and the stamping mechanism mostly relies on simple time relay control, lacking precise position detection and feedback. This often leads to problems such as "stamping before the material is in place" or "overfeeding," posing safety hazards and reducing production efficiency. Utility Model Content

The stamping mechanism is installed at the output end of the feeding mechanism, and a controller is installed on the top of the stamping mechanism. The feeding mechanism includes a platform with a groove in the middle, the groove being arranged along the conveying direction, a pushing unit being installed inside the groove, and a straightening unit being arranged on both sides of the platform, the running direction of the straightening unit being perpendicular to the running direction of the pushing unit.

[0015] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example: like Figures 1 to 4 As shown, this utility model embodiment provides a metal stamping device with automatic feeding function, including a feeding mechanism 1 and a stamping mechanism 2. The stamping mechanism 2 is installed at the output end of the feeding mechanism 1, and a controller 3 is installed on the top of the stamping mechanism 2. The feeding mechanism 1 includes a platform 21, and a groove 22 is provided in the middle of the platform 21. The groove 22 is arranged along the conveying direction, and a pushing unit 23 is installed inside the groove 22. Alignment units 24 are provided on both sides of the platform 21, and the running direction of the alignment units 24 is perpendicular to the running direction of the pushing units 23. The pushing unit 23 includes a T-shaped push plate 231, and the bottom of the T-shaped push plate 231... A connecting block 232 is fixed, and a lead screw 233 is connected through the connecting block 232. The connecting block 232 has internal threads, and sliders 234 are provided on both sides of the connecting block 232. A servo motor 235 is installed at the end of the lead screw 233 away from the stamping mechanism 2. The servo motor 235 is electrically connected to the controller 3. The straightening unit 24 includes a bidirectional threaded lead screw 241, which passes through the interior of the platform 21. Slider 242 is provided at both ends of the bidirectional threaded lead screw 241. A slide rail 243 is provided at the bottom of the slider 242, and push arms 244 are provided on both sides of the slider 242.

[0017] In this embodiment of the invention, a groove 22 is formed in the middle of the platform 21 of the feeding mechanism 1 along the conveying direction. A pushing unit 23 is installed in the groove 22, and a straightening unit 24 is installed on both sides of the platform 21, with the running direction of the straightening unit 24 perpendicular to the pushing unit 23. In the pushing unit 23, a connecting block 232 is fixed to the bottom of the T-shaped push plate 231. A lead screw 233 passes through the connecting block 232 and engages with the thread inside the connecting block 232. A slider 234 is provided on both sides of the connecting block 232. A servo motor 235 is installed at the end of the lead screw 233 away from the stamping mechanism 2, and the servo motor 235 is electrically connected to the controller 3. In the straightening unit 24, a bidirectional threaded lead screw 241 passes through the interior of the platform 21, and a slider 242 is provided at both ends of the slider 242. A slide rail 243 is provided at the bottom of the slider 242, and a push arm 244 is provided on both sides of the slider. During operation, servo motor 235 drives lead screw 233 to rotate, which in turn drives T-shaped push plate to push material through connecting block 232. Simultaneously, the bidirectional threaded lead screw 241 of the straightening unit 24 rotates, causing slider 242 to move on slide rail 243. Push arm 244 moves accordingly to straighten the material, and controller 3 controls the entire process. This achieves automatic feeding of metal materials. The push unit 23 and straightening unit 24 work together to improve the automation level of feeding. The straightening unit 24 ensures accurate positioning of the material during conveying, reduces manual operation, and improves stamping efficiency and accuracy.

[0018] In one feasible implementation scheme, such as Figures 1 to 4 As shown, a sliding groove 221 is provided on the side wall inside the groove 22, and the sliding groove 221 matches the slider 234. By machining the sliding groove 221 on the side wall inside the groove 22 to match the slider 234, the slider 234 can slide in the sliding groove 221 along the pushing direction. The sliding groove 221 and the slider 234 cooperate to guide and limit the movement of the connecting block 232 and the T-shaped push plate 231, making the pushing unit 23 run more smoothly, avoiding deviation or shaking during the pushing process, and further ensuring the stability and accuracy of feeding.

[0019] In one feasible implementation scheme, such as Figures 1 to 4 As shown, a servo motor 245 is mounted on one end of the bidirectional threaded screw 241, and the servo motor 245 is electrically connected to the controller 3. By mounting the servo motor 245 on one end of the bidirectional threaded screw 241 and electrically connecting it to the controller 3, the controller 3 can control the start, stop, speed, and direction of the servo motor 245, thereby controlling the rotation of the bidirectional threaded screw 241. The controller 3 controls the servo motor 245 to drive the bidirectional threaded screw 241 to rotate, realizing the automated control of the alignment unit 24. This allows for precise adjustment of the push arm 244 according to different material specifications, improving the adjustment accuracy and flexibility of the alignment unit 24 and adapting to the processing needs of materials of different sizes.

[0020] In one feasible implementation scheme, such as Figures 1 to 4 As shown, the stamping mechanism 2 includes a C-shaped frame 11. A mold groove 12 is provided at the bottom of the C-shaped frame 11, and a hydraulic rod 13 is provided at the top of the C-shaped frame 11. A pressure plate 14 is installed at the bottom of the hydraulic rod 13, and a hydraulic pump 15 is installed at the top of the hydraulic rod 13. The hydraulic pump 15 is electrically connected to the controller 3. By providing a mold groove 12 at the bottom of the C-shaped frame 11 of the stamping mechanism 2, installing a hydraulic rod 13 at the top, installing a pressure plate 14 at the bottom of the hydraulic rod 13, and connecting the hydraulic pump 15 to the top of the hydraulic rod 13, the controller 3 starts the hydraulic pump 15 during operation. The hydraulic pump 15 drives the hydraulic rod 13 to extend and retract, causing the pressure plate 14 to move up and down, stamping the material in the mold groove 12. The hydraulically driven stamping method provides sufficient and stable power, ensuring consistency in the stamping process. The controller 3's control of the hydraulic pump 15 automates the stamping action, precisely controlling the stamping force and stroke, thus improving stamping quality and efficiency.

[0021] In one feasible implementation scheme, such as Figures 1 to 4 As shown, a laser beam sensor 4 is installed above the mold slot 12 near the feeding mechanism 1, and the laser beam sensor 4 is electrically connected to the controller 3. By installing the laser beam sensor 4 above the mold slot 12 near the feeding mechanism 1, and electrically connecting the sensor to the controller 3, when material is pushed to the vicinity of the mold slot 12, if it blocks the laser beam, the sensor transmits a signal to the controller 3. The laser beam sensor 4 can accurately detect whether the material has reached the stamping position and promptly feed the signal back to the controller 3. The controller 3 can then control the stamping mechanism 2 to start, preventing malfunction of the stamping mechanism 2 when the material is not in position, thus improving the safety and reliability of the equipment operation.

[0022] In one feasible implementation scheme, such as Figures 1 to 4 As shown, an inductive proximity switch 5 is installed on the platform 21, and the inductive proximity switch 5 is electrically connected to the controller 3. By installing the inductive proximity switch 5 on the platform 21, the switch is electrically connected to the controller 3. When metal material passes through the sensing area of ​​the proximity switch, the switch generates a sensing signal and sends it to the controller 3. The inductive proximity switch 5 can reliably sense the presence of metal material and can be used to detect whether the material has entered the feeding path or whether the feeding is normal, providing the controller 3 with material position information. This facilitates the controller 3's precise control of the feeding mechanism 1, further improving the accuracy and stability of the feeding.

[0023] In this embodiment of the utility model, the metal stamping equipment with automatic feeding function, when the operator places metal material on the platform 21 of the feeding mechanism 1, the inductive proximity switch 5 on the platform 21 senses the presence of the metal material and generates a sensing signal, which is then transmitted to the controller 3 at the top of the stamping mechanism 2. Upon receiving the signal, the controller 3 immediately activates the alignment unit 24. At this time, the servo motor 245, electrically connected to the controller 3, starts working, driving the bidirectional threaded screw 241 to rotate. Because the threads at both ends of the bidirectional threaded screw 241 are in opposite directions, its rotation causes the sliders 242 at both ends to move relative to each other under the limiting action of the bottom slide rail 243. The push arms 244 on both sides of the slider 242 move synchronously, clamping and adjusting the position of the material from both sides, ensuring precise alignment of the material along the conveying direction. After completing the alignment action, the servo motor 245 stops running. After the alignment action is completed, the controller 3 controls the push unit 23 to start. Upon receiving the command, the servo motor 235 starts running, driving the screw 233 to rotate. Because the internal thread of the connecting block 232 engages with the lead screw 233, and the sliders 234 on both sides of the connecting block 232 slide within the grooves 221 on the sidewall of the groove 22, the rotation of the lead screw 233 is converted into linear motion of the connecting block 232, thereby driving the T-shaped pusher plate to push the material forward. During the process of the material being pushed into the stamping mechanism 2, when the material passes the laser beam sensor 4 located above the mold slot 12 near the feeding mechanism 1, it will block the laser signal. The sensor transmits this status to the controller 3, indicating that the material is entering the stamping area. As the pushing unit 23 continues to push, when the material is completely inside the mold slot 12 and no longer blocks the laser signal of the laser beam sensor 4, the sensor sends a signal to the controller 3 indicating that the material has been pushed. After confirming that the material has accurately reached its position, the controller 3 immediately sends a command to the hydraulic pump 15 of the stamping mechanism 2. Hydraulic pump 15 starts, driving hydraulic rod 13 at the top of C-shaped frame 11 to extend and retract downwards, causing pressure plate 14 at the bottom to move towards mold groove 12, performing a stamping operation on the material in mold groove 12. After stamping is completed, hydraulic pump 15 controls hydraulic rod 13 to retract, causing pressure plate 14 to reset, waiting for the next stamping cycle. Throughout the process, controller 3, as the core control unit, receives signals from various sensors and coordinates the operation of various servo motors and hydraulic pump 15, realizing fully automated operation from material loading, alignment, pushing, and positioning detection to stamping. Through the coordinated cooperation of various components, the efficiency and accuracy of the stamping process are ensured.
