[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] Please see Figure 1-4 As shown, this utility model is a stamping die suitable for the production of stainless steel washers, comprising:
[0029] The lower mold 110 has columns 111 fixedly connected to the four corners of its top, and a top plate 120 fixedly connected to the top of the columns 111.
[0030] Fall protection mechanism 300 includes slide rail 310, motor 320, lead screw 330, threaded column 340, connecting rod 350, brake plate 360, and square column 370.
[0031] The slide rail 310 is fixedly connected to the top surface of the top plate 120, the motor 320 is fixedly connected to the side wall of the slide rail 310, the lead screw 330 is fixedly connected to the power output end of the motor 320, two threaded columns 340 are respectively threaded to both ends of the lead screw 330, two connecting rods 350 are respectively rotatably connected to the top of the two threaded columns 340, two brake plates 360 are respectively fixed to the side walls of the two connecting rods 350, two square columns 370 are respectively fixedly connected to the top surface of the top plate 120, and the other ends of the two connecting rods 350 are respectively rotatably connected to the top surfaces of the two square columns 370. When the motor 320 is started, the threads at both ends of the lead screw 330 are opposite. The motor 320 drives the lead screw 330 to rotate, causing the two threaded columns 340 to slide closer together in the slide rail 310. The two threaded columns 340 respectively drive one end of the two connecting rods 350 to slide with the threaded column 340, and the other end rotates on the square column 370. The sliding of the connecting rods 350 drives the brake plates 360 on the side wall of the connecting rods 350 to move.
[0032] The threaded column 340 is fixedly connected to the top of the first connecting column 341, and the connecting rod 350 is fixedly connected to one end of the first rotating tube 351. The first rotating tube 351 is rotatably connected to the first connecting column 341. The square column 370 is fixedly connected to the top of the second connecting column 371, and the connecting rod 350 is fixedly connected to the other end of the second rotating tube 352. The second rotating tube 352 is rotatably connected to the second connecting column 371. While the threaded column 340 drives one end of the connecting rod 350 to slide, it causes the first rotating tube 351 to rotate around the first connecting column 341 and the second rotating tube 352 to rotate around the second connecting column 371.
[0033] A connecting rod 353 is fixedly connected to the side wall of the second rotating tube 352, and a third rotating tube 354 is fixedly connected to the end of the connecting rod 353. The third rotating tube 354 at the end of one connecting rod 353 is rotatably connected to the third rotating tube 354 at the end of the other connecting rod 353. The rotation of the second rotating tube 352 drives the connecting rod 353 to rotate, causing the third rotating tube 354 at the end of one connecting rod 353 to rotate with the third rotating tube 354 at the end of the other connecting rod 353, thereby connecting the two connecting rods 350 together and increasing the overall stability.
[0034] A cylinder 200 is fixedly connected to the top of the top plate 120. The telescopic rod of the cylinder 200 passes through the top plate 120. A long plate 130 is fixedly connected to the end of the telescopic rod of the cylinder 200. An upper mold 140 is fixedly connected to the bottom of the long plate 130. Two guide rods 210 are fixedly connected to both ends of the top surface of the long plate 130. The other end of the guide rod 210 passes through the top plate 120. The top plate 120 is located between two connecting rods 350. After the washer is stamped, the cylinder 200 drives the long plate 130 and the upper mold 140 to rise, so that the upper mold 140 and the lower mold 110 are separated. The long plate 130 drives the guide rod 210 to rise. The connecting rod 350 drives the brake plate 360 to approach the guide rod 210. When they contact, the brake plate 360 is engaged and fixed, thereby fixing the long plate 130 and the upper mold 140 to prevent the long plate 130 and the upper mold 140 from falling and injuring workers due to damage to the cylinder 200.
[0035] Working principle: After the washer is stamped, the cylinder 200 drives the long plate 130 and the upper mold 140 to rise, separating the upper mold 140 from the lower mold 110. The long plate 130 drives the guide rod 210 to rise. After the cylinder 200 stops, the motor 320 is started. The threads at both ends of the lead screw 330 are opposite. The motor 320 drives the lead screw 330 to rotate, causing the two threaded posts 340 to slide closer in the slide rail 310. The two threaded posts 340 respectively drive one end of the two connecting rods 350 to slide with the threaded posts 340, while simultaneously causing the first rotating tube 351 to rotate around the first connecting post 341, and the second rotating tube 352 to rotate around the second connecting post 371. The sliding of the connecting rods 350 causes the brake plate 360 on the side wall of the connecting rods 350 to move. The cylinder 60 moves closer to the side wall of the guide rod 210. When the brake plate 360 contacts the guide rod 210, it brakes and fixes the guide rod 210, thereby fixing the long plate 130 and the upper mold 140. This prevents the long plate 130 and the upper mold 140 from falling and injuring workers due to damage to the cylinder 200. After the worker removes the washer, the reverse motor 320 drives the lead screw 330 to reverse. The lead screw 330 drives the two threaded columns 340 to slide and separate in the slide rail 310. The threaded columns 340 drive one end of the connecting rod 350 to slide. The connecting rod 350 drives the brake plate 360 to disengage from the guide rod 210. At this time, the cylinder 200 is started again to lower the long plate 130 and the upper mold 140, so that the upper mold 140 and the lower mold 110 fit together for the next stamping.
[0036] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0037] It also includes a protective cover 400, which protects the fall arrest mechanism 300. The protective cover 400 has four third round holes 410 at the four corners of its bottom. The top plate 120 has four first threaded holes 121 on its top surface. The four third round holes 410 are threaded to the four first threaded holes 121 and then connected to the threaded third screws 700. After aligning the third round holes 410 with the first threaded holes 121, the third screws 700 are passed through the third round holes 410 and screwed into the first threaded holes 121, so that the protective cover 400 is fixedly connected to the top of the top plate 120.
[0038] The top of the first connecting post 341 has a second threaded hole 342, and the second threaded hole 342 is threaded with a first screw 500. The top of the second connecting post 371 has a fourth threaded hole 372, and the fourth threaded hole 372 is threaded with a second screw 600. After the first screw 500 is screwed into the second threaded hole 342, it prevents the first rotating tube 351 from sliding out of the first connecting post 341 when it rotates. After the second screw 600 is screwed into the fourth threaded hole 372, it prevents the second rotating tube 352 from sliding out of the second connecting post 371 when it rotates.
[0039] A fixed housing 355 is fixedly connected to the side wall of the connecting rod 350. Symmetrical protrusions 356 are fixedly arranged on the inner wall of the fixed housing 355. A third threaded hole 357 is opened on the top surface of the fixed housing 355. A groove 361 is opened on the side wall of the brake plate 360. An arc plate 362 is fixedly connected to one end of the brake plate 360. A second round hole 363 is opened on the surface of the arc plate 362. The protrusions 356 slide within the groove 361. The arc plate 362 is fitted into the top surface of the fixed housing 355. After the third threaded hole 357 coincides with the second round hole 363, a fourth threaded connection is made. After screwing screw 800, aligning groove 361 with protrusion 356, insert brake plate 360 into fixed housing 355. When brake plate 360 is fully inserted, arc plate 362 fits into top of fixed housing 355, and the second round hole 363 coincides with the third threaded hole 357. Then, cover plate 358 fits into arc plate 362, making the first round hole 359 coincide with the second round hole 363. Then, screw the fourth screw 800 through 259 and the second round hole 363 and screw it into the third threaded hole 357 to fix brake plate 360 in fixed housing 355.
[0040] Working principle: When brake plate 360 needs to be replaced due to wear, unscrew the third screw 700 from the first threaded hole 121, slide the protective cover 400 upwards, then unscrew the first screw 500 from the second threaded hole 342 and the second screw 600 from the fourth threaded hole 372 respectively. Separate the first rotating tube 351 from the first connecting post 341 and the second rotating tube 352 from the second connecting post 371, and the connecting rod 350 can be removed. Then unscrew the fourth screw 800 from the third threaded hole 357, remove the first round hole 359, pull the brake plate 360 out of the fixing shell 355, align the groove 361 on the new brake plate 360 with the protrusion 356, and insert the brake plate 360 into the fixing shell 355. When the brake plate 360 is fully inserted, the arc plate 362 fits into the top of the fixing shell 355, and the first connecting rod 350 is removed. The second round hole 363 and the third threaded hole 357 are overlapped. Then, the cover plate 358 is fitted onto the arc plate 362 so that the first round hole 359 and the second round hole 363 are overlapped. Then, the fourth screw 800 is passed through the second round hole 259 and the second round hole 363 and screwed into the third threaded hole 357 to fix the brake plate 360 in the fixed shell 355. Then, the first rotating tube 351 and the second rotating tube 352 are inserted into the first connecting post 341 and the second connecting post 371 respectively. Then, the first screw 500 and the second screw 600 are screwed into the second threaded hole 342 and the fourth threaded hole 372 respectively. Finally, the third round hole 410 is aligned with the first threaded hole 121 and the third screw 700 is passed through the third round hole 410 and screwed into the first threaded hole 121 to fix the protective cover 400 to the top of the top plate 120, thus completing the replacement of the brake plate 360.
