Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing safety protection, in particular to a safety guardrail for a square sheet punching machine. Background Art

[0002] A square punch press is a type of stamping equipment widely used in the hardware, electronics, and machinery industries. It uses compressed air to drive a punch downward at high speed, punching a sheet metal placed on a die. Due to the high impact force and inertia involved in the stamping process, if an operator's fingers accidentally enter the stamping area, serious injury can occur.

[0003] Therefore, in order to ensure the personal safety of operators and improve production safety, it is very important to equip the square punch press with safe and reliable protective devices.

[0004] In order to solve the above problems, some safety protection devices for punching machines have appeared in the prior art. For example, Chinese utility model patent CN214348911U (hereinafter referred to as "Document 1") discloses a pneumatic punching machine with an anti-pinch function, which has protective devices on both sides of the punching machine. The protective devices mainly include guardrails, slots, connecting vertical plates and other components.

[0005] Specifically, the guardrail of Document 1 is fixedly mounted on the connecting vertical plate, and transparent glass is provided inside the guardrail to facilitate observation of the stamping area. When the operator needs to load or adjust the workpiece, the guardrail can be opened or closed by sliding the card slot.

[0006] However, the technical solution disclosed in Document 1 has the following deficiencies:

[0007] Transparent glass is fixedly installed inside the guardrail, which limits the operating space: Although this design can provide certain protection, due to the obstruction of the transparent glass, the operator cannot directly reach into the stamping area with his hands to perform operations, such as using jigs to accurately position and adjust the workpiece.

[0008] The use of jigs is inconvenient: In actual production, jigs are often required to assist in stamping processes, such as positioning, clamping, and guiding complex or small workpieces. The protective device in Reference 1, due to limited space, cannot conveniently use jigs, resulting in inconvenient operation and low efficiency.

[0009] In summary, the punch press safety protection device in the prior art has deficiencies in performing refined operations using jigs and needs further improvement and perfection. Utility Model Content

[0010] In order to overcome the defects in the prior art, the utility model provides a safety guardrail for a square sheet punching machine, which can effectively solve the problem of jig operation.

[0011] The utility model solves the above technical problems through the following technical solutions:

[0012] A safety guardrail for a square punch press, the square punch press comprising a frame, an upper support plate and a lower support plate provided on the frame, an upper punch die provided on the upper support plate, and a lower punch die provided on the lower support plate. The safety guardrail for the square punch press comprises: a mesh cover: the mesh cover is configured as a fence structure parallel to a horizontal plane, the mesh cover is disposed between the upper punch die and the lower punch die, and is located between the upper support plate and the lower support plate, and is used to prevent an operator's hand from entering the punching area. Due to the use of a fence structure parallel to the horizontal plane, the operator's hand can be effectively prevented from entering the punching area from any angle. At the same time, the gaps in the fence structure allow for the entry of a jig, facilitating the use of a jig to position and operate the workpiece in the punching area, thereby achieving both safety and ease of operation.

[0013] Preferably, the mesh cover extends upward from the lower punch to cover the entire punching stroke of the upper punch. Compared to the independent claim, this increases the vertical coverage of the mesh cover, ensuring that the upper punch is protected throughout the entire punching stroke, further improving safety and effectively preventing the risk of operators reaching into the punching area under any circumstances.

[0014] Preferably, the sides of the mesh cover extend to the outside of the upper and lower dies, covering the upper die's stamping stroke from the side. Compared to the previous solution, this increases the mesh cover's horizontal coverage and also covers the upper die's stamping stroke from the side, further reducing the gap between the operator and the stamping area, eliminating potential safety hazards, and achieving more comprehensive safety protection.

[0015] Preferably, the mesh enclosure surrounds the upper and lower dies. Compared to the previous solution, this completely encloses the upper and lower dies while retaining the necessary space for observation and operation. Even in non-fenced areas, opaque partitions or transparent partitions that prevent the jig from reaching inside can be installed. This ensures safety while allowing operators to observe the stamping process from multiple angles and perform multi-angle operations using the jig, achieving a balance between safety and operational convenience.

[0016] Preferably, the mesh cover is provided with an observation window. Compared with the previous solution, the observation window provided on the mesh cover further improves the convenience of observation, enables the operator to observe the stamping process more clearly and intuitively, promptly discovers and handles abnormal situations, and improves the safety of operation.

[0017] In summary, the utility model provides a safety guardrail for a square punch press with a simple structure, safety, reliability and easy operation, which solves the problems existing in the prior art such as the guardrail blocking the operating space and the inconvenience of using jigs, and effectively improves the safety and operating efficiency of the square punch press. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 The present invention is a schematic structural diagram of a safety guardrail for a square punch press according to one embodiment of the present invention. DETAILED DESCRIPTION

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic structural diagram of a safety guardrail for a square punch press according to an embodiment of the present invention. Figure 1 As shown, the utility model provides a safety guardrail for a square punch press, wherein the square punch press 1 includes a frame 2. An upper support plate 3 and a lower support plate 4 are provided on the frame 2, the upper punch 5 is provided on the upper support plate 3, and the lower punch 6 is provided on the lower support plate 4.

[0021] It should be noted that the figure only schematically shows the basic structure of the square punch 1. Its specific structure can be designed and adjusted according to actual needs, such as the punching power source, punching stroke control device, mold installation method, etc. The present utility model does not make specific limitations on this.

[0022] The focus of the utility model is to provide a safe, reliable and easy-to-operate safety guardrail for preventing accidental injuries to operators during the stamping process.

[0023] To this end, the safety guardrail for the square sheet punching machine of the present invention includes a mesh cover 7, which is configured as a fence structure parallel to the horizontal plane. The mesh cover 7 is arranged between the upper punch 5 and the lower punch 6, and is located between the upper support plate 3 and the lower support plate 4, to prevent the operator's hands from reaching into the stamping area.

[0024] Specifically, the mesh cover 7 can be constructed from a plurality of parallel metal rods, with a certain gap between adjacent metal rods, forming a fence structure. This structure effectively blocks the operator's arms from entering the stamping area, while also facilitating observation of the stamping process and operation with jigs. When processing square workpieces, the jigs are generally moved horizontally.

[0025] Furthermore, in order to ensure that the upper punch 5 is in a protective state throughout the entire punching stroke and prevent the operator from putting his hand into the punching area under any circumstances, the mesh cover 7 extends upward from the lower punch 6 to cover the entire punching stroke of the upper punch 5.

[0026] For example, the height of the mesh cover 7 can be set to more than 1.2 times the maximum punching stroke of the upper punch 5. Even when the upper punch 5 is at the highest point, the mesh cover 7 can completely cover the punching area, effectively preventing accidents.

[0027] At the same time, in order to further narrow the gap between the operator and the stamping area, eliminate potential safety hazards, and achieve more comprehensive safety protection, the side of the mesh cover 7 extends to the outside of the upper punch 5 and the lower punch 6, covering the stamping stroke of the upper punch 5 from the side.

[0028] For example, the sides of the mesh cover 7 can extend outward by more than 10 cm and bend downward to form an enclosing structure, thereby protecting the sides of the upper punch die 5 and preventing the operator from inserting his hands into the punching area from the sides.

[0029] Furthermore, in order to completely surround the upper punch 5 and the lower punch 6 while retaining the necessary observation and operation space, so as to facilitate the operator to observe the stamping process from more angles and use the jig to perform multi-angle operations, the mesh cover 7 surrounds the upper punch 5 and the lower punch 6.

[0030] For example, the mesh cover 7 can be designed as a hexahedral structure, completely enclosing the upper punch 5 and the lower punch 6 inside, leaving openings only in the areas where the operator needs to operate, and a fence structure is set at the openings, which ensures both safety and convenience of operation.

[0031] Finally, in order to further enhance the convenience of observation, enable the operator to observe the stamping process more clearly and intuitively, promptly discover and handle abnormal situations, and improve the safety of operation, the mesh cover 7 is provided with an observation window.

[0032] For example, one or more observation windows (not shown) can be provided on the front or side of the mesh cover 7. The observation windows can be made of a transparent, impact-resistant material, such as tempered glass or polycarbonate, to facilitate observation of the stamping area by the operator. The size and position of the observation windows can be adjusted according to actual needs to obtain the best observation effect.

[0033] In summary, the utility model provides a safety guardrail for a square sheet punching machine with a simple structure, safety, reliability and easy operation. By setting a mesh cover of a fence structure parallel to the horizontal plane and reasonably designing the size, shape and position of the observation window of the mesh cover, it can effectively prevent the operator's hands from reaching into the stamping area, while making it convenient for the operator to observe the stamping process and use the jig for operation, solving the problems existing in the prior art such as the guardrail blocking the operating space and the inconvenience of using the jig, and effectively improving the safety and operating efficiency of the square sheet punching machine.

[0034] It should be noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
