[0029] First embodiment

[0030] Please refer to Figure 1-Figure 7An embodiment of one aspect of the present invention provides a stamping waste collection device, comprising a knife entry portion 10 and a receiving portion 20, wherein the knife entry portion 10 is formed with a knife entry cavity 11 and a knife entry edge 12 and a discharge port 13 connected to the knife entry cavity 11, the knife entry edge 12 is used to correspond to the punching knife setting, so that the punching knife can enter the knife entry cavity 11, and the diameter width of the knife entry cavity 11 gradually decreases from the knife entry edge 12 to the discharge port 13; the receiving portion 20 is formed with a receiving cavity 21 connected to the discharge port 13, for accommodating stamping waste, and the diameter width D1 of the discharge port 13 is smaller than the diameter width D2 of the receiving cavity 21, for limiting the stamping waste from rebounding to the knife entry portion 10.

[0031] Specifically, since the punch knife needs to use strong pressure during the stamping process, the stamping waste is easy to splash everywhere. The diameter and width of the knife entry cavity 11 are set to gradually decrease from the knife entry edge 12 to the discharge port 13. On the one hand, this is to match the shape of the punch knife so that the inner wall of the knife entry cavity 11 can be configured to match the gap with the outer wall of the punch knife. In this way, after the punch knife enters the knife entry cavity 11, it is equivalent to blocking the knife entry edge 12, and it is difficult for the stamping waste to jump out of the knife entry cavity 11; on the other hand, considering that the space in the knife entry cavity 11 gradually shrinks in the direction of the punch knife's movement, the knife entry portion 10 plays a certain guiding role for the punch knife, thereby improving the accuracy of stamping. The diameter width D1 of the discharge port 13 is set to be smaller than the diameter width D2 of the accommodating cavity 21, so that the accommodating portion 20 forms a blockage on the outer periphery of the discharge port 13 on the side close to the discharge port 13, further increasing the range of obstruction to the stamping waste jumping into the knife cavity 11, further reducing the damage to the product surface and the damage to the mold equipment by the stamping waste, and improving the production yield and efficiency. The diameter width D2 of the accommodating cavity 21 being greater than the discharge port 13 is also conducive to avoiding the accumulation of stamping waste, and avoiding the stamping waste congested at the discharge port 13 affecting the smooth punching and shearing of the punch.

[0032] In this embodiment, the inner wall of the knife entry portion 10 corresponding to the knife entry cavity 11 is inclined from the knife entry edge 12 to the material discharge opening 13 to form a first angle α of ≥0.2° and ≤1°.

[0033] Preferably, the first angle α is 0.3°-0.6°.

[0034] Specifically, the main purpose of the inclination angle of 0.2°-1° is to configure a punching blade of a specific shape to prevent an excessively large gap from forming between the punching blade and the inner wall of the corresponding entry cavity 11 in the entry portion 10, thereby allowing stamping waste to enter the entry cavity 11 and thus affect the operation of the equipment and product yield. Depending on the shape of the punching blade configured, the angle of the first angle α can be specifically 0.35°, 0.4°, 0.45°, 0.5°, 0.55° or 0.6°, etc., and is not limited here. The optimal value of the first angle α can be set to 0.4°.

[0035] In this embodiment, a shielding wall 22 is provided on the side of the accommodating portion 20 close to the blade entry portion 10. The shielding wall 22 is a shield formed by the accommodating portion 20 on the outer periphery of the discharge port 13 on the side close to the discharge port 13. The inner wall of the corresponding blade entry cavity 11 in the blade entry portion 10 and the shielding wall 22 form a second angle β of ≤89.8°. According to the first angle α formed by the inner wall of the corresponding blade entry cavity 11 in the blade entry portion 10 tilting from the blade entry 12 to the discharge port 13, the angle is 0.2°-1°. The second angle β formed by the inner wall of the corresponding blade entry cavity 11 in the blade entry portion 10 and the shielding wall 22 is preferably 89°-89.8°, that is, the shielding wall 22 is perpendicular to the punching direction of the punch.

[0036] Specifically, the inner wall of the knife entry cavity 11 in the knife entry portion 10 converges inward, and the diameter width D2 of the accommodating cavity 21 is greater than the diameter width D1 of the discharge port 13, so that the shielding wall 22 expands outward from the direction close to the discharge port 13. When the second angle β formed by the shielding wall 22 and the inner wall of the knife entry cavity 11 is greater than 89.8°, the shielding of the stamping waste by the shielding wall 22 may cause the stamping waste to gather in the middle. Since the stamping waste itself has uncertainty in direction, it is extremely difficult to It is possible that after being impacted and energized by the shielding wall 22, the material may jump toward the knife cavity 11. When the second angle β formed by the shielding wall 22 and the inner wall of the knife cavity 11 is less than or equal to 89°, it can ensure that the stamping waste is pressed vertically downward or dispersed to the surroundings. In particular, when the second angle β is less than 89°, a dead angle is formed between the shielding wall 22 and the inner wall of the accommodating cavity 21. When the stamping waste enters the dead angle, it can only fall vertically downward or within a small range. Correspondingly, since the optimal value of the first angle α in this embodiment is set to 0.4°, the optimal value of the second angle β is set to 89.6°.

[0037] In this embodiment, the depth H1 of the accommodating cavity 21 is 5 cm-10 cm.

[0038] Specifically, the accommodating cavity 21 needs to be set to a certain depth to avoid the punching blade from working and to leave enough space to accommodate the stamping waste. In actual settings, the depth H1 of the accommodating cavity 21 can be 5.6 cm, 6.2 cm, 6.8 cm, 7.5 cm, 8.1 cm, 8.9 cm, 9.6 cm, etc., which is not limited here.

[0039] In this embodiment, the depth H2 of the cutting cavity 11 is 1 cm-3 cm.

[0040] Specifically, the depth H2 of the knife entry cavity 11 is mainly used to configure the conventional height of the punch. In actual settings, the depth H2 of the knife entry cavity 11 can be 1.2 cm, 1.6 cm, 1.8 cm, 2.2 cm, 2.5 cm, 2.8 cm, etc., which is not the only limitation here.

[0041] In this embodiment, a material holding portion 30 is further included. The material holding portion 30 is disposed between the discharge port 13 and the accommodating cavity 21 . The material holding portion 30 is provided with a material holding cavity 31 for buffering stamping waste.

[0042] Specifically, the clamping portion 30 can apply force to the stamping waste to change the center of gravity and discharge trajectory of the waste, ensure that the stamping waste can fall smoothly and be captured by the collection device, adjust the discharge trajectory of the stamping waste, and prevent the waste from interfering or getting stuck during the falling process. The clamping portion 30 can also prevent the stamping waste from deforming, so as to reduce the possibility of deformation and jamming of the stamping waste, and facilitate the processing of the stamping waste.

[0043] In this embodiment, the diameter D3 of the clamping cavity 31 is smaller than or equal to the minimum inner diameter of the cutting cavity 11 .

[0044] Specifically, in this embodiment, the diameter D3 of the clamping cavity 31 is preferably equal to the minimum inner diameter of the knife inlet cavity 11, that is, the inner diameter of the clamping cavity 31 is uniform and equal to the diameter D1 of the discharge port 13, so as to achieve effective collection of stamping waste.

[0045] In this embodiment, the depth H3 of the material holding cavity 31 is the distance from the discharge port 13 to the accommodating cavity 21 , and H3 is 0.3 cm-1 cm.

[0046] Specifically, the width H3 and depth of the card cavity 31 are set to adapt to the discharge trajectory of the stamping waste. In actual applications, the depth H3 of the card cavity 31 can be 0.32cm, 0.38cm, 0.45cm, 0.51cm, 0.57cm, 0.63cm, 0.72cm, 0.77cm, 0.86cm, 0.9cm, 0.95cm, etc., which is not the only limitation here.

[0047] The stamping waste collection device provided in this embodiment sets the diameter width D2 of the accommodating cavity 21 to be larger than the diameter width D1 of the discharge port 13, so that when the punch enters the cutter cavity 11 to perform stamping processing, the stamping waste generated at the cutting point tends to be concentrated in a larger gap, and the punch occupies the space in the cutter cavity 11, so that the stamping waste is blocked from rebounding to the outside of the stamping waste collection device through the cutter cavity 11, which can reduce the product crushing rate and avoid abnormal equipment shutdown.

[0049] Another embodiment of the present invention provides a coil stamping line, including a punching knife, a driver and a stamping waste collection device as described in the first embodiment. The punching knife is arranged corresponding to the entry edge 12, and the driver is used to drive the punching knife to enter or exit the entry cavity 11 from the entry edge 12.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to be covered by the scope of protection of the present invention.
