However, due to the cumulative error between the loading and stamping processes, there is a possibility that the stamped parts fail to leave the stamping table, resulting in mold damage. In this case, the mold needs to withstand a huge impact force, which can exceed the mold's bearing capacity, causing damage to mold parts (such as the punch and die). Damage to the mold not only increases maintenance costs but also may affect product quality and production efficiency. Utility Model Content

[0024] 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.

[0026] like Figure 1As shown, a stamping part detection device is used to be set at the discharge outlet of the stamping machine 6 to detect whether the stamping part 100 has left the lower die 63 of the stamping machine 6. It includes a first carrier 1 and a detector 2. The detector 2 is rotatably connected to the first carrier 1. The detector 2 is fixedly connected to a trigger 3. The trigger 3 is rotatably connected to the first carrier 1. A slide rail 4 is provided on the top of the trigger 3. The slide rail 4 is used to connect to the discharge end of the lower die 63. The stamping part 100 falls into the slide rail 4 from the discharge end of the lower die 63. The slide rail 4 is provided with a clearance hole 41. The trigger 3 partially passes through the clearance hole 41. When a stamping part 100 slides over the slide rail 4, the stamping part 100 drives the trigger 3 to rotate, and the trigger 3 drives the detector 2 to rotate. When the detector 2 rotates a specific angle, the detector 2 receives a signal that the stamping part 100 has passed, and feeds it back to the stamping machine 6, and the stamping machine 6 performs the stamping operation.
[0027] like Figure 1 and Figure 2 As shown, specifically, the first carrier frame 1 includes a first adjustable frame body 11, a support block 12, and a support plate 13. The support block 12 and the support plate 13 are both fixedly connected to the ends of the first adjustable frame body 11. The first adjustable frame body 11 can adjust the positions of the support block 12 and the support plate 13 in the vertical and horizontal directions. This is common knowledge and will not be described in detail here. A gap is left between the support plate 13 and the support block 12. The detector 2 is rotatably connected to the support plate 13. The support block 12 has a built-in connecting rod 14. The connecting rod 14 is rotatably connected to the support block 12 via a bearing. One end of the connecting rod 14 is fixedly connected to the rotation center of the detector 2, and the other end is fixedly connected to the rotation center of the trigger member 3.
[0028] The rotational axis of the trigger member 3 is skewed and perpendicular to the axial centerline of the slide rail 4. Specifically, the rotational axis of the connecting rod 14 is horizontal, while the trigger member 3 is vertical. The stamping member 100 slides along the centerline of the slide rail 4, that is, along the length of the slide rail 4. The stamping member 100 forces the trigger member 3 to rotate, which in turn drives the detector 2 to rotate.
[0029] In this embodiment, the detector 2 is an encoder. When the stamping part 100 slides down the slide rail 4, it touches the trigger part 3. The trigger part 3 rotates with the encoder through the connecting rod 14. The encoder determines whether the stamping part 100 has slid through the slide rail 4 by judging its own rotation angle. Specifically, when the encoder rotation angle is greater than or equal to 155°, the encoder will output a signal to the PLC control electronic control box, and the PLC control electronic control box will then feed this signal back to the stamping machine 6. In other variations, the encoder rotation angle is affected by factors such as the product type of the stamping part 100 and the inclination angle of the slide rail 4. Therefore, the encoder rotation angle is not limited to the above angles, and other angles adjusted according to actual conditions are within the protection scope of this implementation.
[0030] In this embodiment, the slide rail 4 is provided with two blocking parts 42, which are fixed to the edge of the slide rail 4 along the length direction of the slide rail 4. The two blocking parts 42 limit the moving path of the stamping part 100 along the length direction of the slide rail 4, thereby avoiding the risk of the stamping part 100 detaching from the slide rail 4 during the sliding process in the slide rail 4.
[0031] A number of protrusions 31 protrude evenly from the edge of the trigger member 3. Specifically, the protrusions 31 extend in a direction away from the center of the trigger member 3. The protrusions 31 can hook out the stamping part 100, so that when the stamping part 100 moves along the slide rail 4, the stamping part 100 drives the trigger member 3 to rotate, and there is no relative sliding between the stamping part 100 and the trigger member 3. The detector 2 can accurately reflect the moving distance of the stamping part 100 through the clearance hole 41, reducing the risk of misjudgment by the detector 2.
[0032] A stamping parts detection device is also provided with a second supporting frame 5, which includes a second adjustable frame 51 and an angle adjustment block 52. The angle adjustment block 52 is adjustably arranged on the second adjustable frame 51, and the second adjustable frame 51 can adjust the position of the angle adjustment block 52 in the vertical and horizontal directions. The above is common knowledge and will not be repeated here. Specifically, the angle adjustment block 52 is fixedly connected to the bottom of the slide rail 4, and the angle adjustment block 52 is adjustably connected to the second adjustable frame 51 by bolts. In this embodiment, the adjustable connection means that the angle adjustment block 52 is sleeved on the second adjustable frame 51, and the bolts are tightened to fix the angle adjustment block 52 to the second adjustable frame 51. Loosening the bolts allows the angle adjustment block 52 to rotate relative to the second adjustable frame 51, thereby adjusting the angle of the slide rail 4.
[0033] like Figure 3 As shown, the present application also provides a stamping machine 6 for stamping a stamping part 100, including a stamping part detection device, and also including a frame 61 and a carrier 62. The carrier 62 is fixed on the frame 61, and the carrier 62 is provided with a plurality of mounting slots 621 distributed in an array. The first carrier 1 and the second carrier 5 can be detachably connected to the mounting slot 621. The carrier 62 is provided with a lower die 63, and the lower die 63 is detachably mounted on the mounting slot 621. The frame 61 also includes a stamping cylinder 64 and an upper die 65. The stamping cylinder 64 is fixed on the frame 61, and the upper die 65 is fixed on the stamping cylinder 64. The stamping cylinder 64 drives the upper die 65 to move toward the lower die 63, thereby stamping the stamping part 100 located at the lower die 63. The detector 2 is electrically connected to the stamping cylinder 64 through the PLC electrical control box.
[0034] The frame 61 is provided with an automatic unloading device, and one end of the slide rail 4 is close to the discharge port of the lower die 63. In this embodiment, the slide rail 4 is slightly lower than the discharge port, so that the automatic unloading device can directly feed the stamping part 100 onto the slide rail 4. The slide rail 4 is set at an angle. The automatic unloading device can adopt a pneumatic unloading device or a push rod type unloading device. The above are common knowledge and will not be repeated in this embodiment. Specifically, the central axis of the slide rail 4 is set at an acute angle to the horizontal plane. Preferably, the central axis of the slide rail 4 is 30° to the horizontal plane, so that the stamping part 100 drives the trigger part 3 to rotate on the slide rail 4 at an angle greater than or equal to 155°. The detector 2 can accurately generate a feedback signal.
[0035] Principle of operation: After the stamping part 100 is stamped in the lower die 63, the automatic unloading device pushes the stamping part 100 out of the discharge port of the lower die 63, and the stamping part 100 falls onto the slide rail 4, sliding along the length of the slide rail 4. When the stamping part 100 passes through the clearance hole 41, the stamping part 100 abuts against the protrusion 31. The stamping part 100 drives the trigger part 3 to rotate through the protrusion 31, and the trigger part 3 drives the detector 2 to rotate. When the detector 2 rotates to or exceeds the set angle, the detector 2 feeds back a signal to the stamping machine 6, indicating that the stamping part 100 has left the lower die 63. A new stamping part 100 to be stamped is fed into the lower die 63, and the next stamping can be carried out.
[0036] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
