With the continuous improvement of production automation and efficiency requirements, the frequency of use and workload of cutting and stamping dies have increased significantly.

[0003] Existing equipment typically uses electric linear actuators to push materials into the processing area. During this process, the actuators can only perform simple linear pushing motions. Because the initial position of the material may be off, the actuators cannot perform secondary adjustments or precise positioning, making it difficult to ensure the material is in the ideal processing position upon entering the processing area, leading to decreased processing accuracy. Furthermore, existing electric linear actuator systems are poorly adaptable to materials of different specifications and shapes, unable to adjust the pushing force and speed according to material characteristics, easily resulting in incomplete material delivery or deviation during the pushing process. Therefore, improvements are needed to address these issues. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a safety protection mold for anti-splash cutting and stamping, comprising a top plate 1, a first electric push rod 2 installed in the center of the bottom surface of the top plate 1, four first telescopic rods 3 fixedly connected to the periphery of the bottom surface of the top plate 1, a base 4 fixedly connected to one end of each first telescopic rod 3, a discharge frame 5 on one side of the top surface of the base 4, an inlet frame 6 on the other side of the top surface of the base 4, a cutting table 7 between the discharge frame 5 and the inlet frame 6, and an upper mold 11 fixedly connected to the output shaft of the first electric push rod 2; the top plate 1 is made of high-strength aluminum alloy, which is lightweight and high-strength, and can stably support the first electric push rod 2 and other components; the first electric push rod 2 is a DT-50 model, with stable thrust, and can accurately control the lifting and lowering of the upper mold 11; the first telescopic rods 3 are also provided. Rod 3 is made of 45# steel, hardened to ensure high hardness and stability, and works in conjunction with base 4 to ensure overall structural stability. Base 4 is made of cast iron, which is wear-resistant and can withstand long-term stamping operations. The discharge frame 5 and feed frame 6 clearly define the material entry and exit paths, facilitating material management. This structure realizes the basic framework of the mold, providing a stable foundation for subsequent processing operations and improving the reliability and durability of the mold. Two conveyor belts 12 are symmetrically arranged on both sides of the cutting table 7 and feed frame 6. Push blocks 13 are provided on the conveyor belts 12. Two rotating shafts for driving the conveyor belts 12 are provided at both ends of the cutting table 7 and feed frame 6. One of the two rotating shafts is coaxially fixed to a motor 15. Machine 15, model Y90S-4, has stable power and can flexibly adjust its speed according to the material characteristics, thereby controlling the running speed of the conveyor belt 12 and the pushing force of the pusher block 13. The conveyor belt 12 is made of rubber with high surface friction, which can prevent the material from slipping during the conveying process. The pusher block 13 is made of polytetrafluoroethylene, which is wear-resistant and will not damage the material surface. This conveying structure can realize the stable conveying of materials of different specifications and shapes, accurately pushing the materials to the processing area, solving the problem of poor adaptability of the electric pusher in existing equipment, and improving the efficiency and accuracy of material conveying. The cutting table 7 is equipped with a lower mold 14 corresponding to the upper mold 11. The upper mold 11 is surrounded by a pressure block 8, and the top surface of the pressure block 8 is... Three second telescopic rods 10 are evenly distributed at the triangular section and installed on the bottom surface of the top plate 1. A second electric push rod 9 is fixedly connected to one corner of the top surface of the pressure block 8 and installed on the bottom surface of the top plate 1. The second electric push rod 9 is a DT-30 model and can precisely control the downward stroke and force of the pressure block 8. The second telescopic rod 10 is made of stainless steel, which has good guiding properties and can ensure the smooth lifting and lowering of the pressure block 8. The pressure block 8 is made of engineering plastic, which is lightweight and has a certain degree of toughness. It can perform secondary positioning and fixing of the material before stamping. During stamping, it forms a protective barrier around the upper mold 11, which effectively prevents metal chips from splashing. This structure solves the problems of insufficient material positioning accuracy and chip splashing during processing, and improves processing accuracy and operational safety.

[0020] In this invention, the pressure block 8 has a rectangular frame shape on its horizontal plane. This rectangular frame design allows the pressure block 8 to completely enclose the mold 11, forming a closed protective space. Compared to other shapes, it provides better blocking of flying debris, further enhancing the mold's anti-splash performance and providing a safer working environment for operators. A mounting groove is provided in the center of the bottom surface of the cutting table 7, and a third electric push rod 16 is installed in the mounting groove. A discharge push plate 17, which is attached to the inner top surface of the lower mold 14, is fixed to the telescopic end of the third electric push rod 16. The third electric push rod 16 is a DT-20 model with moderate thrust, capable of discharging the stamped sheet metal. The lower mold 14 is successfully ejected; the ejector plate 17 is made of nylon with a smooth surface that will not scratch the surface of the sheet metal; this ejection structure realizes the automated ejection of the sheet metal after stamping without manual intervention, solving the problem of inconvenient ejection of existing equipment, improving production efficiency, and reducing the labor intensity and safety risks of operators; the feed frame 6 is located on one side of the cutting table 7 and has a rectangular discharge port; the design of the rectangular discharge port makes the path of material from the feed frame 6 into the cutting table 7 smoother, reduces material jamming, ensures the continuity of material conveying, and helps to improve the efficiency of the overall processing flow.

[0021] Working principle: When this utility model is used, the motor 15 starts to drive the conveyor belt 12 to rotate, and the pusher block 13 on the conveyor belt 12 pushes the material placed in the feed frame 6 to move towards the cutting table 7; the motor 15 can adjust the speed according to the specifications and shape of the material, control the speed of the conveyor belt 12 and the pushing force of the pusher block 13, so as to achieve stable and accurate conveying of different materials; after the material reaches the position of the lower mold 14 of the cutting table 7, the first electric push rod 2 extends to drive the upper mold 11 to move down, and at the same time the second electric push rod 9 extends to push the pressure block 8 down; the pressure block 8 is guided by the second telescopic rod 10. The material is positioned and fixed for a second time. Then, the upper mold 11 continues to descend and cooperates with the lower mold 14 to complete the cutting and stamping. The rectangular frame-shaped pressure block 8 surrounds the upper mold 11 to prevent debris from splashing. After the stamping is completed, the first electric push rod 2 retracts and drives the upper mold 11 to rise. The second electric push rod 9 retracts and drives the pressure block 8 to rise. Then, the third electric push rod 16 extends and pushes the discharge push plate 17 on the bottom of the cutting table 7 to push the plate out from the lower mold 14 to the discharge frame 5. The third electric push rod 16 retracts and resets the discharge push plate 17, waiting for the next processing cycle. At this point, the device is used.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
