Description

Technical Field

[0001] This utility model relates to the field of punch press technology, and in particular to a punch press with protective functions. Background Technology

[0002] In modern manufacturing, punch presses are an important metal processing equipment widely used in automobile manufacturing, aerospace, electronic communications, and daily necessities. Punch presses use molds to stamp and form metal sheets, offering advantages such as high production efficiency and good processing precision. However, with the continuous improvement of production demands, safety issues during the use of punch presses have become increasingly prominent. To address this, a punch press with protective functions has emerged, achieving a perfect combination of high-efficiency production and safety assurance through advanced technological innovation. However, existing punch press structures still have some shortcomings in terms of protective functions. These shortcomings not only affect production safety but also limit the performance of punch press equipment.

[0003] Existing punch press protective structures often only focus on local protection, such as simply shielding the punch head, but lack comprehensive protection for the overall operating environment. Secondly, some punch press safety protection devices have design flaws, such as inconvenient opening of safety doors and insecure fixing of protective covers, which makes it easy for operators to ignore or deliberately bypass these protective devices during production, increasing safety risks. Utility Model Content

[0004] The present invention proposes a punch press with protective function, which solves the problems of incomplete protective function and unreasonable design of safety protection devices in existing punch presses with protective function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A punch press with protective function includes a base, inside which multiple sets of damping telescopic rods are arranged, and springs are arranged on the outer side of the damping telescopic rods. A movable plate is connected to the top of the damping telescopic rods, and the punch press body is arranged on the top of the movable plate. Clamping mechanisms are arranged on both sides of the punch press body, and a worktable is arranged on the top of the punch press body. An adjustable first electric telescopic rod is arranged on the top of the worktable, and a fixed plate is arranged on the side of the first electric telescopic rod. Vertical plates are arranged on both sides of the worktable at the top of the base, and an L-shaped cover plate is arranged on the top of the base at one end, and an automatically opening and closing protective door is arranged on the top of the base at the other end. A start switch is arranged on the side of the L-shaped cover plate.

[0007] Preferably, the clamping mechanism includes clamping plates, knobs, and threaded posts, and clamping plates are provided on both sides of the punch press body inside the base. Threaded posts are connected to the sides of the clamping plates and extend to the outside of the base. Knobs are provided on the sides of the threaded posts to form a clamping structure.

[0008] Preferably, the top side of the workbench is provided with multiple sets of threaded holes, and a mounting plate is provided above the threaded holes. A first electric telescopic rod is provided on the top of one end of the mounting plate, and the side of the mounting plate at the other end is limited and connected to the threaded holes by bolts.

[0009] Preferably, a second electric telescopic rod is provided at the upper center of the L-shaped cover plate, and an upper mold is provided at the bottom of the second electric telescopic rod.

[0010] Preferably, the other end of the base is provided with a through hole that matches the protective door, and slide rails are provided on both sides of the through hole. The protective door is provided with sliders that match the slide rails and are slidably connected.

[0011] Preferably, a rack is provided on one side of the protective door, and a drive motor is provided inside the lower part of the upright plate. The output end of the drive motor is connected to a drive gear, and the drive gear meshes with the rack.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This protective punch press has multiple sets of damping telescopic rods inside the base, and springs are installed on the outside of the damping telescopic rods. When the punch is working, the worktable will be subjected to the pressure of the punch. The worktable presses downward against the punch press body. The damping telescopic rods and springs inside the base will reduce the downward force of the punch. At the same time, the clamping plates on both sides of the punch press body, through manual rotation of the knob and threaded column, make the punch press more stable during operation. If displacement occurs, the operator can tighten it by rotating the knob and threaded column. This makes the punch press more convenient to maintain, reduces the vibration and displacement generated during operation, protects the worktable and lower die, and is conducive to the longer use of the punch press.

[0014] 2. An automatic opening and closing protective door is installed on the top of the other end of the base. The drive motor is started by the start switch. The drive motor, together with the rack and pinion and the drive gear, makes the protective door move upward in the slide, effectively preventing dangerous substances such as splashes and debris from entering the operating area, improving the safety of using the punch press, protecting the operator, and making the operator more at ease when operating the punch press. At the same time, it indirectly promotes the improvement of the punch press's processing efficiency. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1-4 This utility model provides a technical solution: a punch press with protective function, including a base 1, with multiple sets of damping telescopic rods 2 inside the base 1, and springs 3 on the outer side of the damping telescopic rods 2. A movable plate 4 is connected to the top of the damping telescopic rods 2, and a punch press body 5 is mounted on the top of the movable plate 4. Clamping mechanisms are provided on both sides of the punch press body 5, and a worktable 6 is mounted on the top of the punch press body 5. An adjustable first electric telescopic rod 7 is mounted on the top of the worktable 6, and a fixing plate 8 is mounted on the side of the first electric telescopic rod 7. Upright plates 9 are mounted on both sides of the worktable 6 at the top of the base 1, and an L-shaped cover plate 10 is mounted on the top of one end of the base 1, while an automatically opening and closing protective door 11 is mounted on the top of the other end of the base 1. A start switch 24 is mounted on the side of the L-shaped cover plate 10. This simplifies the operation steps, allows the operator to quickly and accurately complete the opening and closing operation, and improves work efficiency and safety.

[0022] Reference Figure 2 , Figure 3The clamping mechanism includes a clamping plate 12, a knob 13, and a threaded post 14. The clamping plates 12 are located inside the base 1 on both sides of the punch press body 5. The threaded posts 14 are connected to the sides of the clamping plates 12 and extend to the outside of the base 1. The knobs 13 are located on the sides of the threaded posts 14 to form a clamping structure. By manually rotating the knobs 13 and the threaded posts 14, the punch press is more stable during operation, which protects the worktable 6 and the lower die 26 and is conducive to the long-term use of the punch press. The top side of the worktable 6 is provided with multiple sets of threaded holes 15, and a mounting plate 16 is provided above the threaded holes 15. A first electric telescopic rod 7 is provided on the top of one end of the mounting plate 16, and the other end of the mounting plate 16 is limited to the threaded holes 15 by bolts 17. The upper die is clamped by the first electric telescopic rod 7 and the fixing plate 8 to ensure the quality and accuracy of the stamping. A second electric telescopic rod 25 is provided in the middle of the upper part of the L-shaped cover plate 10, and the upper die 26 is provided at the bottom of the second electric telescopic rod 25.

[0023] Reference Figure 1 , Figure 4 The other end of the base 1 has a through hole 18 that matches the protective door 11, and slide rails 19 are provided on both sides of the through hole 18. The protective door 11 has sliders 20 that match the slide rails 19 on both sides and are slidably connected. A rack 21 is provided on the side of the protective door 11, and a drive motor 22 is provided at the bottom of the upright plate 9. The output end of the drive motor 22 is connected to a drive gear 23, and the drive gear 23 meshes with the rack 21. The automatically opening and closing protective door 11 effectively prevents dangerous substances such as splashes and debris from entering the operating area, thus improving the safety of using the punch press.

[0024] Specifically, in use, the punch press with protective function first presses the start switch 24, which starts the drive motor 22. The drive motor 22, in conjunction with the rack 21 and the drive gear 23, causes the protective door 11 to move downward in the slide rail 19, and vice versa. Then, the workpiece to be punched is clamped between the first electric telescopic rod 7 and the fixed plate 8, and the protective door 11 is closed.

[0025] When the punch is working, the worktable 6 is subjected to the pressure of the punch. The worktable 6 presses down on the punch body 5. The damping telescopic rod 2 inside the base 1 works with the spring 3 to reduce the downward force of the punch. At the same time, a limit block (not shown in the figure) is set inside the base 1 to protect the stroke of the spring 3 and prevent excessive punching from damaging the spring 3. Manually rotating the knob 13 and the threaded column 14 makes the punch more stable when it is working. If displacement occurs, the operator can tighten it by rotating the knob 13 and the threaded column 14, which protects the worktable 6 and the lower die and is conducive to the longer use of the punch.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
