A first connecting rod 404 is connected through one side of the surface, a second threaded cylindrical pin 405 is movably sleeved on the other side of the first connecting rod 404, a sliding block 406 is connected through one side of the surface of the second threaded cylindrical pin 405, a fixed sleeve 407 is slidably connected to one side of the surface of the sliding block 406, a second connecting block 408 is fixedly connected to one side of the surface of the connecting sleeve 401, a first limiting block 409 is fixedly connected to one side of the second connecting block 408, a third threaded cylindrical pin 410 is movably sleeved on one side of the second connecting block 408, a second connecting rod 411 is connected through one side of the surface of the third threaded cylindrical pin 410, and the second connecting rod 411 The other side of the fourth threaded cylindrical pin 412 is movably sleeved, and one side of the surface of the fourth threaded cylindrical pin 412 is threadedly connected to the stamping machine slider surface 413. During use, the second connecting rod 411 of the stamping machine protection device can be fixed to the stamping machine slider surface 413 through the fourth threaded cylindrical pin 412 in advance, and the fixed base 1 and the fixed sleeve 407 are fixed on the workbench after determining a suitable position. After that, the operator puts in the scraps and starts the stamping machine. At this time, the stamping machine will slide the stamping machine slider surface 413 downward, and the downward sliding of the stamping machine slider surface 413 will drive the second connecting rod 411 to rotate, and the second connecting rod 411 will rotate. The other end of the rod 411 will rotate with the second connecting block 408 and push the second connecting block 408. Affected by the second connecting rod 411, the second connecting block 408 and the connecting sleeve 401 will rotate with the transmission shaft 3. At the same time, the connecting sleeve 401 will drive the first connecting block 402 to rotate. The rotation of the first connecting block 402 will drive the first connecting rod 404 to move. The other end of the first connecting rod 404 will rotate with the sliding block 406 and push the sliding block 406. The sliding block 406 will slide with the fixed sleeve 407, thereby completing the motion conversion to ensure that the subsequent protection measures of the stamping machine tool protection device can run smoothly.

[0022] Furthermore, the first connecting rod 404 forms a rotating structure with the first connecting block 402 through the first threaded cylindrical pin 403, and the first connecting rod 404 forms a rotating structure with the sliding block 406 through the second threaded cylindrical pin 405.

[0024] Furthermore, the first limit block 409 is fitted with the second connecting rod 411, and the connecting sleeve 401 forms a rotating structure through the side plate 2, the transmission shaft 3 and the fixed base 1. Through the setting of the first limit block 409 and the second connecting rod 411, the first limit block 409 can limit the rotation angle of the second connecting block 408 and the second connecting rod 411, preventing the second connecting block 408 from forming an angle of 180° with the second connecting rod 411, thereby ensuring the smooth operation of the stamping machine tool protection device.

[0025] Furthermore, the sensing mechanism 5 includes a third connecting block 501, a laser sensor 502, a loudspeaker 503 and a second limiting block 504. One side of the fixed sleeve 407 is fixedly connected to the third connecting block 501, one side of the third connecting block 501 is fixedly connected to the laser sensor 502, one end of the fixed sleeve 407 is fixedly connected to the loudspeaker 503, and one end of the sliding block 406 is fixedly connected to the second limiting block 504. During use, when the stamping machine is stationary and not working, the second limiting block 504 will fit with the fixed sleeve 407, and the laser sensor 502 will not sense When the second limit block 504 is reached, the laser sensor 502 will not trigger the loudspeaker 503 to broadcast. When the stamping machine is processing scraps, the slider surface 413 of the stamping machine moves downward. After the transformation of the protective mechanism 4, the sliding block 406 will drive the second limit block 504 to move. When the second limit block 504 moves, it will be sensed by the laser sensor 502. When the laser sensor 502 senses the second limit block 504 and the sliding block 406, it will trigger the loudspeaker 503 to broadcast to remind the operator to complete the corresponding operation, which is beneficial to ensuring the personal safety of the operator.

[0026] Furthermore, the second limit block 504 is slidably connected to the fixed sleeve 407 through the sliding block 406. Through the setting of the second limit block 504, the sliding block 406 and the fixed sleeve 407, the second limit block 504 can slide with the sliding block 406 and the fixed sleeve 407, thereby facilitating the laser sensor 502 to sense the second limit block 504 and the sliding block 406, thereby ensuring the processing of the entire part.

[0027] Working principle: During use, the second connecting rod 411 of the stamping machine tool protection device can be fixed in advance to the slider surface 413 of the stamping machine tool through the fourth threaded cylindrical pin 412, and the fixed base 1 and the fixed sleeve 407 are fixed on the workbench to determine the appropriate position. Then the operator puts in the scraps. Through the setting of the first limit block 409 and the second connecting rod 411, the first limit block 409 can limit the rotation angle of the second connecting block 408 and the second connecting rod 411 to prevent the second connecting block 408 from forming an angle of 180° with the second connecting rod 411, thereby ensuring the smooth operation of the stamping machine tool protection device. Start the stamping machine tool. At this time, the stamping machine tool will slide the slider surface 413 of the stamping machine tool downward. When the stamping machine tool is stationary and not working, the second limit The positioning block 504 will fit with the fixing sleeve 407, and the laser sensor 502 does not sense the second positioning block 504, and the laser sensor 502 will not trigger the speaker 503 to broadcast. When the stamping machine processes scraps, the slider surface 413 of the stamping machine moves downward. After the transformation of the protective mechanism 4, the sliding block 406 will drive the second positioning block 504 to move. When the second positioning block 504 moves, it will be sensed by the laser sensor 502. When the laser sensor 502 senses the second positioning block 504 and the sliding block 406, it will trigger the speaker 503 to broadcast to remind the operator to complete the corresponding operation, which greatly improves the operator's operating safety. The model of the laser sensor 502 is: NA11, and the model of the speaker 503 is: NS1pro.
