[0033] Please see Figure 1-9 This utility model provides a technical solution: a protective device suitable for both sides of a punch press, including a punch press body 1 and a protective assembly. The protective assembly is disposed on the punch press body 1 and includes a connecting plate 2, which is fixedly connected to the side of the punch press body 1. A fixed shaft 3 is fixedly connected to the upper end of the connecting plate 2. Two hinges 6 are rotatably connected to the surface of the fixed shaft 3. A first acrylic plate 4 is disposed on the surface of the fixed shaft 3 and is fixedly connected to the two hinges 6. A first acrylic plate 4 is fixedly connected to the surface of the first acrylic plate 4. Multiple protrusions 8 are provided. A second acrylic plate 5 is slidably sleeved on the surface of the first acrylic plate 4. Multiple first grooves 9 are provided on the inner wall of the second acrylic plate 5. The multiple protrusions 8 are slidably connected to the corresponding first grooves 9. A first limiting groove 10 is provided on the surface of the first acrylic plate 4. The first limiting groove 10 is in the shape of an inverted "E". A second limiting groove 11 is provided on the surface of the second acrylic plate 5. A limiting rod 12 is slidably connected inside the second limiting groove 11. The limiting rod 12 is engaged with the first limiting groove 10. The limiting rod 12 is in the shape of a dumbbell.
[0034] The protective components are arranged in two sets, symmetrically on the left and right sides of the press body 1.
[0035] The multiple protrusions 8 on the surfaces of the two first acrylic plates 4 and the multiple first grooves 9 on the surfaces of the two second acrylic plates 5 are located on the front and rear sides of the corresponding first acrylic plates 4.
[0036] A damping device 7 is fixedly connected to the surface of the fixed shaft 3 on the right side. A second slide groove 14 is opened on the surface of the damping device 7. A limit block 15 is slidably connected to the inner wall of the second slide groove 14. A damping spring 16 is arranged inside the second slide groove 14. The two ends of the damping spring 16 are fixed to the inner wall of the second slide groove 14 and the limit block 15, respectively. There are multiple second slide grooves 14, limit blocks 15 and damping springs 16 arranged in a ring array on the damping device 7.
[0037] The damping device 7 and its corresponding second slide groove 14, limit block 15 and damping spring 16 are all symmetrically arranged on the two fixed shafts 3 in four sets. The surface of the first acrylic plate 4 is provided with a groove that cooperates with the damping device 7.
[0038] Handles 13 are fixedly connected to the front and rear sides of the two second acrylic plates 5 respectively.
[0039] When using the device, there are two sets of protective components, symmetrically installed on the left and right sides of the press body 1; the connecting plate 2 is fixed to the side of the press body 1 to provide support for the entire protective component; the fixed shaft 3 is firmly installed on the press through the connecting plate 2, and the two hinges 6 are rotatably connected to the fixed shaft 3, thereby connecting the first acrylic plate 4, so that the first acrylic plate 4 can rotate around the fixed shaft 3, and initially forming a protective area on both sides of the press.
[0040] The second acrylic plate 5 is slidably connected to the protrusion 8 on the surface of the first acrylic plate 4 through the first sliding groove 9 on the inner wall. After installation, the two are in a relatively stable initial position. The limiting rod 12 is located in the second limiting groove 11 and is engaged with the first limiting groove 10 to fix the second acrylic plate 5 on the first acrylic plate 4 and prevent it from sliding at will.
[0041] During normal operation of the punch press, two sets of protective components prevent personnel or objects from accidentally entering the working area of the punch press from the left and right sides; the first acrylic plate 4 and the second acrylic plate 5 are made of acrylic material, which has a certain degree of transparency, does not hinder the operator from observing the internal situation of the punch press, and can effectively block foreign objects to avoid injury to personnel caused by the punch press's stamping action.
[0042] When the size of the protected area needs to be adjusted, the operator holds the handles 13 on both the front and rear sides of the second acrylic plate 5 and applies pulling or pushing force. Due to the cooperation between the protrusion 8 and the first sliding groove 9, the second acrylic plate 5 can slide smoothly on the surface of the first acrylic plate 4. During the sliding process, the limiting rod 12 slides synchronously in the second limiting groove 11. When it slides to the appropriate position, the limiting rod 12 will be locked into the slots at different positions of the first limiting groove 10 to lock the position of the second acrylic plate 5, thereby adjusting the width of the protected area to adapt to different working scenarios.
[0043] To facilitate the adjustment of the angle of the protective plate in special operation scenarios such as loading and unloading materials, the first acrylic plate 4 is rotated. At this time, the damping device 7 on the right fixed shaft 3 plays a role, and the limiting block 15 in the second slide groove 14 on the surface of the damping device 7 slides accordingly. The damping spring 16 is squeezed or stretched, generating damping force. This makes the rotation process of the first acrylic plate 4 smooth and slow, avoiding the safety hazards caused by rapid rotation.
[0044] When the first acrylic plate 4 is rotated to the appropriate angle, the limiting block 15 on the damping device 7 will cooperate with the groove opened on the surface of the first acrylic plate 4 to stabilize the first acrylic plate 4 at that angle; and the four sets of damping devices 7 symmetrically arranged on the two fixed shafts 3 can ensure the consistency and stability of the protective components on both sides when adjusting the angle.
[0045] Furthermore, the first acrylic plate 4 and the second acrylic plate 5 on both sides are installed on both sides of the punch press via a fixed shaft 3 and a hinge 6. The first acrylic plate 4 and the second acrylic plate 5 are movable. During operation, the baffle protects both sides, preventing personnel or objects from accidentally entering the punching work area and causing personnel safety accidents. The size of the overlapping part of the two acrylic plates can be adjusted according to actual needs, thereby changing the width of the protected area, improving the practicality and convenience of the device, enhancing the protective effect of the device, and improving the safety of the device.
[0046] Furthermore, by setting up the damping device 7, the limiting block 15 and the damping spring 16 can generate a certain resistance to the first acrylic plate 4 during the rotation process, which makes the rotation process of the first acrylic plate 4 smooth and slow, avoiding the safety hazards caused by rapid rotation and improving the safety and protection effect of the device.

[0051] The second acrylic plate 5 has a first sliding groove 9 on its inner wall that is slidably connected to the protrusion 8 on the surface of the first acrylic plate 4, allowing it to slide smoothly on the surface of the first acrylic plate 4 to adjust the width of the protective area; the second limiting groove 11 is used to accommodate the limiting rod 12, which works with the first limiting groove 10 to fix its own position; the handles 13 on the front and rear sides make it convenient for operators to manually slide the second acrylic plate 5 to adjust the size of the protective area.
[0052] Hing 6: Connects the first acrylic plate 4 and the fixed shaft 3, allowing the first acrylic plate 4 to rotate freely relative to the fixed shaft 3. It plays a key role in connection and rotation support during the adjustment of the protection angle, ensuring the flexibility and stability of the rotation of the first acrylic plate 4.
[0053] Damping device 7: Fixed on the surface of the right fixed shaft 3, the second slide groove 14, the limiting block 15 and the damping spring 16 on it work together to generate damping force when the first acrylic plate 4 rotates, so that the rotation process is smooth and slow, and prevents the safety risks caused by rapid rotation; four sets of damping devices 7 are symmetrically arranged on the two fixed shafts 3 to ensure the consistency and stability of the protective components on both sides when adjusting the angle; the limiting block 15 can also cooperate with the groove on the surface of the first acrylic plate 4 to stabilize the angle of the first acrylic plate 4 after rotation;
[0054] The protruding strip 8 is fixed to the surface of the first acrylic plate 4 and cooperates with the first sliding groove 9 on the inner wall of the second acrylic plate 5 to provide guidance and support for the sliding of the second acrylic plate 5, ensuring that the second acrylic plate 5 slides smoothly on the surface of the first acrylic plate 4 and realizing precise adjustment of the width of the protective area.

[0056] First limiting groove 10: It is opened on the surface of the first acrylic plate 4 in the shape of an inverted "E" and is engaged with the limiting rod 12. By locking the second acrylic plate 5 in different positions through different groove positions, the width of the protective area can be precisely adjusted to meet the protection needs of different working scenarios.
[0057] The second limiting groove 11 is formed on the surface of the second acrylic plate 5 and has a limiting rod 12 slidably connected inside. It works together with the first limiting groove 10 to limit the sliding range of the second acrylic plate 5 and ensure its stability and reliability during the width adjustment process.
[0058] Limiting rod 12: It is dumbbell-shaped and slides in the second limiting groove 11. It engages with the first limiting groove 10 to effectively prevent the second acrylic plate 5 from sliding at will and to fix it firmly in different positions on the first acrylic plate 4, thereby fixing the width of the protective area.
[0059] Handle 13: Installed on the front and rear sides of the two second acrylic plates 5, making it convenient for operators to grip and apply force, making it easier and more convenient to adjust the position of the second acrylic plates 5, and improving the operability of the protective device;
