[0029] like Figures 1 to 4 As shown, this application proposes a floating blanking die, which includes a first elastic component, an upper die base 1, an upper template 2, a second elastic component, a lower template 3, and a lower pad 4. The upper die base 1 and the upper template 2 are provided with a communicating receiving space. The first elastic component passes through the receiving space and can reciprocate along the receiving space. The lower template 3 and the lower pad 4 are connected by the second elastic component, and there is a buffer space 33 between the lower template 3 and the lower pad 4 supported by the second elastic component. The first elastic component can push the lower template 3 to make the lower template 3 move in the vertical direction. The first elastic component and the second elastic component in this utility model can effectively reduce the damage to the product structure caused by factors such as die inertia when the die is opened and closed.
[0030] like Figure 2As shown, in this embodiment, the accommodating space includes a first accommodating hole 21 and a second accommodating hole 22. The first elastic component includes a first elastic element 23, a push rod 24, and a first bolt 25. The first accommodating hole 21 and the second accommodating hole 22 are interconnected. In this embodiment, the first elastic element 23 is a spring, while in other embodiments, the first elastic element 23 can be other elastic structures. The first elastic element 23 is disposed in the first accommodating hole 21, and the push rod 24 is hung on the side wall of the first accommodating hole 21 and passes through the second accommodating hole 22. That is, the diameter of the first accommodating hole 21 is larger than the diameter of the second accommodating hole 22. At the same time, a recess is provided in the second accommodating hole 22 near the first accommodating hole 21. The push rod 24 is configured as a "T" shape and overlaps the second accommodating hole. The lateral length of the ejector pin 24 head is greater than the opening diameter of the second receiving hole 22 at the connection point, so the ejector pin 24 can be hung on the side wall of the first receiving hole 21 without falling out of the channel of the second receiving hole 22. Simultaneously, the spring diameter of the first elastic element 23 placed in the first receiving hole 21 is smaller than the lateral length of the ejector pin 24 head, ensuring that when the tail of the ejector pin 24 is subjected to force, the first elastic element 23 can provide a reaction force to the head of the ejector pin 24. Furthermore, the first bolt 25 is tightened to the end of the first elastic element 23 away from the ejector pin 24 to press against the first elastic element 23, preventing the first elastic element 23 from popping out of the first receiving hole 21 after being subjected to force. Through the cooperation of the first elastic element 23 and the ejector pin 24 in the receiving space, a buffering effect can be provided for the mold during mold opening and closing, preventing damage to the product structure when the mold opening and closing process is too fast or lacks buffering.
[0031] Specifically, the head of the ejector rod 24 located in the first receiving hole 21 abuts against the first elastic member 23, and the tail of the ejector rod 24 passes through and extends out of the second receiving hole 22. This ensures that during mold opening and closing, the ejector rod 24 extends out of / retracts into the second receiving hole 22 by bearing / resisting the elastic force of the first elastic member 23. It can be understood that the compressible length of the first elastic member 23 under force is greater than or equal to the length of the tail of the ejector rod 24 extending out of the second receiving hole 22, so as to ensure that the ejector rod 24 can be completely retracted into the second receiving hole 22 after being subjected to force, preventing damage to the product during mold closing. This solution adds a buffer stage to the mold opening and closing process, preventing damage to the product structure or the production of defective products due to excessively fast or forceful mold opening and closing.
[0032] like Figure 3As shown, the floating blanking die in this embodiment also includes a lower die base 5. The second elastic component includes a second elastic element 31 and a guide rod. In this embodiment, the guide rod is a second bolt 32, and the second elastic element is a spring. Other elastic structures can also be used in other embodiments. The second bolt 32 is sequentially inserted through the lower die base 5, the lower pad 4, and the lower template 3, and the second bolt 32 is tightened to the lower template 3 or movably disposed within the lower template 3. The lower pad 4 is provided with a receiving groove 41, and the second elastic element 31 is sleeved on the second bolt 32 and placed in the receiving groove 41. The solution is that one end of the second elastic member 31 abuts against the unopened side wall of the receiving groove 41; the other end abuts against the lower template 3 near the opening end of the receiving groove 41. Since the second elastic member 31 has elasticity, and its elasticity is sufficient to support the lower template 3 so that it does not contact the lower pad 4, there is a buffer space 33 between the lower template 3 and the lower pad 4 formed by the elasticity of the second elastic member 31. When the mold is opened and closed, the second elastic member 31 and the buffer space 33 can give the lower template 3 more buffer time and space when the mold is opened and closed, so as to avoid damage to the structure of the bottom of the product caused by the mold opening and closing too quickly.
[0033] like Figure 4 As shown, the present invention also provides a continuous punching line. In this embodiment, the lower die plate 3 is connected to an external feeding device 6. A power device is provided at the bottom of the feeding device 6. The power device cooperates with the second elastic component to ensure that when the first elastic component and the second elastic component play a buffering role in the mold opening and closing process, the external feeding device 6 can keep in line with the movement state of the lower die plate 3 in the vertical direction, so as to reduce the feeding waiting time and improve the synchronization.
[0034] Specifically, the lower template 3 is provided with a positioning hole 34, and the external feeding device 6 is provided with a positioning pin 61. The positioning hole 34 and the positioning pin 61 cooperate to connect the lower template 3 and the external feeding device 6. Connecting the external feeding device 6 to the lower template 3 together allows the external feeding device 6 to move synchronously with the lower template 3 when the mold is opened and closed. At the same time, the second elastic element 31 provides vertical power to the lower template 3 and the external feeding device 6, avoiding the situation where the feeding device cannot move synchronously with the mold after adding a buffer structure, thus reducing the feeding speed and increasing the product production cycle.
[0035] Specifically, in this embodiment, there are at least two positioning holes 34, and correspondingly, there are at least two positioning pins 61 to prevent slippage when a single positioning hole 34 and positioning pin 61 are engaged, which would make the connection between the lower template 3 and the external feeding device 6 unstable. Furthermore, the dimensions of the positioning holes 34 and positioning pins 61 need to be calculated and selected according to the actual parameters of the external feeding device 6 to ensure that the positioning holes 34 and positioning pins 61 can bear the weight of the external feeding device 6 without breaking.
[0036] Specifically, a material changing device (not shown) is also provided on one side of the floating blanking die. After the floating blanking die completes the blanking, the material changing device moves the product to be processed on the feeding device 6 and replaces it into the cavity of the floating blanking die. It is particularly important to note that the lower template 3 is connected to the external feeding device 6, and a power device is provided at the bottom of the feeding device 6. The power device cooperates with the second elastic element to realize the synchronous up and down movement of the lower template 3 and the external feeding device 6. Therefore, when transferring the product to be processed, the material changing device only needs to move horizontally, without the need for up and down movement as in the prior art, thus improving processing efficiency.
[0037] In addition, the upper template 2 and the lower template 3 in this embodiment are provided with contour grooves (not shown in the figure) that match the product, so as to process and produce the product that needs to be processed.
[0038] In use, the external feeding device 6 is used to transport the product to be processed using its own horizontal feeding belt (not shown in the figure). At the same time, the material changing device transports the product to be processed into the contour groove. The power system of the upper mold drives the mold to close. When the tail of the ejector rod 24 contacts and pushes the lower template 3, the lower template 3 moves downward, causing the second bolt 32 to move downward as well. At the same time, the second elastic element 31 under pressure is compressed, and the buffer space 33 gradually decreases. When the buffer space 33 completely disappears, the lower template 3 contacts the lower pad 4. At this time, the mold is still not closed. The power system continues to apply force, and the tail of the ejector rod 24 continues to abut against the lower template 3. Since the lower template 3 is now in contact with the lower pad 4, it can no longer move downward. At this time, the head of the ejector rod 24 compresses the first elastic element 23, and the ejector rod 24 gradually retracts into the second receiving hole 22 until the ejector rod 24 is completely retracted into the second receiving hole 22. At this time, the upper template 2 contacts the lower template 3, and the mold closes. After the work is completed, the first elastic element 23 applies pressure to the ejector rod 24, causing the tail of the ejector rod 24 to continuously abut against the lower mold plate 3. Under the elastic force of the first elastic element 23, the upper mold plate 2 disengages from the lower mold plate 3. When the head of the ejector rod 24 abuts against the side wall of the first receiving hole 21 again, the ejector rod 24 returns to the state before mold closing. At this time, the upper mold plate 2 continues to rise, and the tail of the ejector rod 24 no longer abuts against the lower mold plate 3. At this time, the lower mold plate 3 loses pressure, and the second elastic element 31 provides elastic force to the lower mold plate 3 again, causing it to move upward and re-form the buffer space 33. When the lower mold plate 3 moves upward under the elastic force of the second elastic element 31, it will exhibit up-and-down oscillating motion. However, since the lower mold plate 3 is connected to the external feeding device 6, the second elastic element 31 provides vertical power to the lower mold plate 3 and the external feeding device 6 at the same time. That is, the lower mold plate 3 and the external feeding device 6 maintain synchronous movement in the vertical direction. The next feeding can be carried out without waiting for the lower mold plate 3 to stop, and the above mold closing and opening process is repeated.
[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
