[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] Please combine them together Figures 1 to 6 The stamping testing machine provided by this utility model will now be described.

[0035] The stamping testing machine includes: a frame 1, a drive assembly 2, a transmission assembly 3, and an execution assembly 4. The drive assembly 2 includes a drive motor 21, a drive module 22, a main shaft 23, an eccentric wheel 24, and a bearing sleeve 25. The drive motor 21 is mounted on the frame 1 and is connected to the main shaft 23 via the drive module 22. The drive motor 21 is used to drive the drive module 22 to rotate the main shaft 23. The main shaft 23 is detachably connected to the eccentric wheel 24. The bearing sleeve 25 is fitted onto the eccentric wheel 24 and is connected to the execution assembly 4 via the transmission assembly 3. The eccentric wheel 24 and the bearing sleeve 25 are detachably connected.

[0036] It is understood that the drive motor 21 of the stamping experimental machine is mounted on the frame 1. The drive motor 21 is connected to the main shaft 23 through the drive module 22 and is used to drive the drive module 22 to rotate the main shaft 23. The main shaft 23 is detachably connected to the eccentric wheel 24. The bearing sleeve 25 is fitted on the eccentric wheel 24 and is connected to the execution component 4 through the transmission component 3. The eccentric wheel 24 and the bearing sleeve 25 are detachably connected. Because the main shaft 23 and the eccentric wheel 24 are detachably connected, and the bearing sleeve 25 and the eccentric wheel 24 are detachably connected, the eccentric wheel 24 and the bearing sleeve 25 with different parameters can be replaced. This allows the stamping experimental machine to adjust the mechanism parameters according to the experimental requirements and visualize the motion trajectory, thereby meeting the needs of teaching experiments.

[0037] It should be noted that the drive motor 21 drives the drive module 22 to rotate the main shaft 23, the main shaft 23 drives the eccentric wheel 24 to rotate, the eccentric wheel 24 drives the bearing sleeve 25 to move, and the bearing sleeve 25 drives the execution component 4 to perform the stamping motion through the transmission component 3.

[0038] It should be added that the main shaft 23 is rotatably connected to the frame 1 through the bearing housing. The main shaft 23 is detachable from the bearing housing. The main shaft 23 is also connected to the eccentric wheel 24 through the connecting key, so that the eccentric wheel 24 can be removed from the main shaft 23, thereby replacing the eccentric wheel 24 with different parameters, thus improving the diversity of experiments.

[0039] In this embodiment, the bearing sleeve 25 includes a first bearing 251, a second bearing 252, and a fastener 253. The first bearing 251 is opposite to the second bearing 252, and the fastener 253 can fasten the first bearing 251 and the second bearing 252. Specifically, the fastener 253 is a bolt. The fastener 253 can fasten the first bearing 251 and the second bearing 252, making the first bearing 251 and the second bearing 252 detachable, thereby facilitating the replacement of eccentric wheels 24 with different parameters and the replacement of matching bearing sleeves 25.

[0040] In one embodiment, such as Figures 2 to 6 As shown, the drive module 22 has multiple implementations:

[0041] In one embodiment, the drive module 22 includes a first pulley 221, a second pulley 222, and a belt 223. A drive motor 21 is fixedly connected to the first pulley 221 and drives it to rotate. The second pulley 222 is rotatably connected to the frame 1 and to the main shaft 23. The belt 223 surrounds the first pulley 221 and the second pulley 222. The drive motor 21 drives the first pulley 221 to rotate, which in turn drives the belt 223 to move. The belt 223 then drives the second pulley 222 to rotate, which in turn drives the main shaft 23 to rotate. The main shaft 23 then drives the eccentric wheel 24 to rotate, which in turn drives the bearing sleeve 25 to move. The bearing sleeve 25, through the transmission assembly 3, then drives the actuation assembly 4 to perform a stamping motion.

[0042] In another embodiment, the drive module 22 includes a first sprocket 224, a second sprocket 225, and a transmission chain 226. A drive motor 21 is fixedly connected to the first sprocket 224 and drives its rotation. The second sprocket 225 is rotatably connected to the frame 1 and connected to the main shaft 23. The transmission chain 226 surrounds the first sprocket 224 and the second sprocket 225. The drive motor 21 drives the first sprocket 224 to rotate, which in turn drives the transmission chain 226 to move. The transmission chain 226 then drives the second sprocket 225 to rotate, which in turn drives the main shaft 23 to rotate. The main shaft 23 then drives the eccentric wheel 24 to rotate, which in turn drives the bearing sleeve 25 to move. The bearing sleeve 25, through the transmission assembly 3, then drives the actuation assembly 4 to perform a stamping motion.

[0043] In another embodiment, the drive module 22 includes a first gear 227 and a second gear 228. A drive motor 21 is fixedly connected to the first gear 227 and drives it to rotate. The second gear 228 is rotatably connected to the frame 1 and connected to the main shaft 23. The first gear 227 and the second gear 228 mesh. The drive motor 21 drives the first gear 227 to rotate, which in turn drives the second gear 228 to rotate. The second gear 228 then drives the main shaft 23 to rotate, which in turn drives the eccentric wheel 24 to rotate. The eccentric wheel 24 then drives the bearing sleeve 25 to move, and the bearing sleeve 25, through the transmission assembly 3, drives the actuation assembly 4 to perform a stamping motion.

[0044] The various types of drive modules 22 described above enable diversified teaching demonstrations.

[0045] In one embodiment, such as Figure 4 As shown, the transmission assembly 3 includes a first connecting frame 31, a first connecting member 32, a first profile 33, a second connecting member 34, a third connecting member 35, a second profile 36, a fourth connecting member 37, a second connecting frame 38, a third profile 39, and a fifth connecting member 391. The first connecting frame 31 is detachably connected to the frame 1. The first connecting member 32 is rotatably connected to the first connecting frame 31. One end of the first profile 33 is detachably connected to the first connecting member 32, and the other end is detachably connected to the second connecting member 34. The second connecting member 34 is also rotatably connected to the third connecting member 35. One end of the second profile 36 is detachably connected to the third connecting member 35, and the other end is detachably connected to the fourth connecting member 37. The fourth connecting member 37 is rotatably connected to the second connecting frame 38. The second connecting frame 38 is connected to the actuating assembly 4. One end of the third profile 39 is detachably connected to the bearing sleeve 25, and the other end is detachably connected to the fifth connecting member 391. The fifth connecting member is rotatably connected to the second connecting member 34. In this way, the first profile 33, the second profile 36, and the third profile 39 of different sizes can be replaced, thereby improving the different parameter requirements of the experiment.

[0046] In this embodiment, the execution component 4 includes a first connecting plate 41, a first adjusting member 42, a second connecting plate 43, a second adjusting member 44, a third connecting plate 45, a connecting post 46, and a fixing plate 47.

The connecting post 46 is fixed to the fixing plate 47, and the third connecting plate 45 is slidably connected to the connecting post 46. The first adjusting member 42 can adjust the distance between the first connecting plate 41 and the second connecting plate 43, and the second adjusting member 44 can adjust the distance between the second connecting plate 43 and the third connecting plate 45, thereby adjusting the stamping stroke of the third connecting plate 45.

[0047] Furthermore, the first adjusting member 42 includes a column 421, a sliding member 422, and a locking member 423. The sliding member 422 is fixed to the first connecting plate 41 and slidably connected to the column 421. The column 421 is fixed to the second connecting plate 43. The locking member 423 can lock the sliding member 422 and the column 421. In this way, after the sliding member 422 moves the first connecting plate 41 to a suitable position, the locking member 423 locks the sliding member 422 onto the column 421, thereby keeping the sliding member 422 in its current position.

[0048] Furthermore, the second adjusting member 44 includes a stud 441, a first nut 442, and a second nut 443. The stud 441 is fixed to the third connecting plate 45. The first nut 442 and the second nut 443 are both threadedly connected to the stud 441 and clamp the second connecting plate 43. Adjusting the position of the first nut 442 and the second nut 443 on the stud 441 adjusts the position of the second connecting plate 43.

[0049] In one embodiment, such as Figure 1 As shown, frame 1 is a structural component made of aluminum profile. This allows for the display of the internal structure of the stamping testing machine and a more intuitive observation of the internal motion trajectory.
