DETAILED DESCRIPTION

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0032] In the description of the present invention, "several" means an indefinite quantity, "multiple" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, and "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" is solely for the purpose of distinguishing technical features and should not be understood to indicate or imply relative importance, or to implicitly indicate the number or order of the technical features indicated. "And / or" throughout the text represents three parallel solutions. For example, "A and / or B" means a solution where A satisfies, a solution where B satisfies, or a solution where both A and B satisfy.

[0033] In the description of the present invention, if there is a short sentence containing multiple parallel features, the attributive defines the closest feature. For example, "B, C, and E are arranged on A, and E is connected to D" means that B is arranged on A and E is connected to D, and does not constitute a limitation on C. However, attributives that express the relationship between features, such as "spaced arrangement" and "circular arrangement", do not fall into this category.

For example, "B, C, and D are all arranged on A" means that B, C, and D are all arranged on A. In a sentence with an omitted subject, the omitted subject is the subject of the previous sentence, that is, "B is arranged on A, including C" means that B is arranged on A and A includes C.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] The following combination Figures 1-6 The following describes an embodiment of the present invention by taking the example of a punching device that is installed at the rear side of the installation as an example.

[0036] This embodiment relates to a safety protection device also used for stamping equipment, comprising: a mounting platform 100 and a detection assembly;

[0037] The mounting platform 100 is provided with a first mounting frame 110 and a second mounting frame 120 spaced apart in the left-right direction. The first mounting frame 110 includes a first column 111, a second column 112, and a first crossbeam 113. The first crossbeam 113 is arranged between the first column 111 and the second column 112. The two ends of the first crossbeam 113 are respectively connected to the first column 111 and the second column 112. The first column 111 and the second column 112 are both provided on the mounting platform 100.

[0038] The detection component includes a transmitter 210 and a receiver 220. The transmitter 210 is arranged in the middle of the first beam 113 and suspended above the mounting platform 100. The receiver 220 is connected to the second mounting bracket 120 and suspended above the mounting platform 100. The transmitter 210 is arranged toward the receiver 220.

[0039] A detection component is provided, and when an object enters between the transmitter 210 and the receiver 220, a feedback signal is generated so as to perform operations such as shutdown, thereby realizing the function of safety protection; compared with the structural form of the protective net, it is less obstructive to workers. In addition, the transmitter 210 in the present invention is connected to the mounting platform 100 through the first mounting frame 110 in the shape of a "door" and is suspended above the mounting platform 100, thereby reducing the impact of the vibration generated by the external stamping equipment impacting the workbench on the transmitter 210. At the same time, the installation of the transmitter 210 is relatively stable, thereby improving the stability of operation.

[0040] In this embodiment, the detection component is a safety grating, which has the advantages of complete design and low cost.

[0041] Furthermore, the second mounting frame 120 includes a third column 121, a fourth column 122, and a second crossbeam 123. The second crossbeam 123 is mounted between the third column 121 and the fourth column 122, with both ends of the second crossbeam 123 connected to the third column 121 and the fourth column 122, respectively. The third column 121 and the fourth column 122 are both mounted on the mounting platform 100, and the receiver 220 is located in the middle of the second crossbeam 123. The "door" shape of the second mounting frame 120 ensures a more stable installation of the receiver 220, which is mounted in the middle of the second crossbeam 123. Furthermore, since the receiver 220 is suspended from the mounting platform 100, the impact of vibrations from the mounting platform 100 on the receiver 220 is further reduced.

[0042] Furthermore, the safety protection device also includes a double movable door assembly 300, which includes a connecting frame 310, a rear door body 330, and a front door body 320. The rear door body 330 and the front door body 320 are both rotatably connected to the mounting platform 100 via the connecting frame 310. The rear door body 330 and the front door body 320 rotate between an open position and a closed position. A seal 340 is formed at the lower end of the front door body 320 for covering the gap between the front door body 320 and the mounting platform 100. The double movable door assembly 300 is provided, and the rear door body 330 is configured to cover the main body of the stamping equipment to provide protection and safety protection for the main body. The front door body 320 is configured to cover the lower part of the stamping equipment, covering the part of the stamping equipment adjacent to the mounting platform 100, that is, covering the part of the stamping equipment that stamps the workpiece. The open position and the closed position refer to the positions where the door body remains stable in the open state and the closed state. The positions are not unique and may vary depending on the relationship between the components.

[0043] Furthermore, the upper portion of the connecting frame 310 is provided with a first hole arranged horizontally and a first limiting groove arranged vertically; the double movable door assembly 300 also includes a front connecting column 321, a first connecting block 322, a first limiting connecting block 323 and a first screw, the front door body 320 is connected to the lower side of the front connecting column 321, and the upper portion of the front connecting column 321 is hinged to the first hole through a first axis; the upper portion of the front connecting column 321 is provided with a first connecting block 322 extending horizontally; the first connecting block 322 is provided with a vertical through The first connecting block 322 is provided with a second hole and a third hole. The second hole, the mounting slot, and the third hole are connected in sequence. A first limiting connecting block 323 is provided in the mounting slot. The first screw passes through the second hole, the first limiting connecting block 323, and is threadedly connected to the third hole in sequence, clamping the first limiting connecting block 323 in the mounting slot. A limiting rod 324 is formed on the first limiting connecting block 323. The limiting rod 324 swings with the front connecting column 321 to abut or separate from the first limiting slot. Through the above arrangement, the limiting rod 324 formed on the first limiting connecting block 323 can be used to limit the front door body 320 to the closed position. After the front door body 320 is closed, it can be firmly maintained in the closed position. It can be understood that at this time, the front door body 320 is in a tilted state away from the limiting rod 324 in the closed position. In addition, the first limiting connection block 323 is clamped in the installation groove by the second screw, and the two end surfaces of the first limiting connection block 323 respectively abut against the two end surfaces of the installation groove, and the first limiting connection block 323 and the installation groove are temporarily fixed by friction. Therefore, when the closing force of the front side door body 320 is too large, the relative sliding between the first limiting connection block 323 and the two end surfaces of the installation groove reduces the impact generated when the limiting rod 324 abuts against the first limiting groove, thereby playing a safety protection role for the first limiting rod 324, reducing the chance of damage to the first limiting rod 324, and improving durability.

[0044] Furthermore, a first locking post 325 is provided laterally extending from the first connecting block 322. Accordingly, a first locking arm 311 is rotatably connected to the connecting frame 310. The first locking arm 311 is provided with a first locking slot 3111. The first locking slot 3111 engages with the first locking post 325 in the open position and locks the first locking post 325. When the front door 320 is rotated upward, the first locking arm 311 rotates, causing the first locking slot 3111 to engage with the first locking post 325, thereby locking the front door 320 in the open position. This makes operation more convenient.

[0045] Furthermore, a first magnet 312 is provided at the bottom of the connecting frame 310. The double movable door assembly 300 also includes a rear connecting post 331. A second magnet 332 is provided at the bottom of the rear connecting post 331. The second magnet 332 and the first magnet 312 attract each other in the closed position. By providing the first magnet 312 and the second magnet 332 to attract the rear connecting post 331, the rear connecting post 331 can maintain a certain degree of stability in the closed position, while also facilitating the rear connecting post 331 to move out of the closed position, thereby facilitating the opening of the rear door 330.

[0046] Furthermore, the upper portion of the connecting frame 310 is provided with a second locking arm 313 that swings laterally. The second locking arm 313 is provided with a second locking slot 3131. Correspondingly, the rear connecting column 331 is provided with a second locking column 333. The second locking column 333 is provided with a locking stop 334. The second locking slot 3131 engages with the second locking column 333 in the open position, and the upper end of the second locking arm 313 abuts the locking stop 334. The provision of the second locking arm and the second locking slot 3131 ensures that the rear door 330 remains locked in the open position, resisting vibrations generated by the stamping equipment during operation. Furthermore, the second locking arm 313 swings laterally to engage with the second locking column 333, making it less likely to become loose.

[0047] Furthermore, a connecting profile 350 is provided on the lower side of the front door body 320. The connecting profile 350 is provided with a through waist-shaped hole. The waist-shaped hole is arranged vertically. A second screw is provided in the waist-shaped hole. The second screw passes through the waist-shaped hole and is threadedly connected to a first screw hole provided on the front door body 320. The first screw hole is formed on a nut fixed to the surface of the front door body 320, thereby locking the connecting profile 350 to the lower part of the front door body 320. The seal 340 is connected to the lower part of the connecting profile 350. The provision of the waist-shaped hole allows the height of the connecting profile 350 to be adjusted, and thus the installation height of the seal 340 can be adjusted.

[0048] Furthermore, the lower portion of the connecting profile 350 is provided with a downwardly extending mounting groove, the middle portion of which is provided with an inwardly extending retaining bar. The upper portion of the seal 340 is formed with an arcuate protrusion 341, which is connected to the middle portion of the seal 340 via an inwardly recessed section 342. The arcuate protrusion 341 is located within the mounting groove, and the inwardly recessed section 342 abuts the retaining bar. The arcuate protrusion 341 is disposed within the mounting groove, and the inwardly recessed section 342 abuts the retaining bar, thereby maintaining a secure connection between the seal 340 and the connecting profile 350. The provision of the arcuate protrusion 341 also allows the seal 340 to be directly installed from the bottom of the mounting groove, making installation of the seal 340 more convenient.

[0049] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention.
