Description

Technical Field

[0001] This utility model belongs to the field of die-cutting, specifically relating to a burr-free edge cutting system. Background Technology

[0002] In the field of precision manufacturing, die-cutting is widely used in the edge processing of mechanical parts, such as fasteners. Traditional die-cutting equipment is prone to generating burrs during the cutting process, affecting the product's appearance and assembly accuracy. This is especially true for metal or hard material workpieces, where burr control is more challenging. Existing technologies mainly address this by optimizing the tool structure or adding a subsequent grinding process. However, the former has limited material adaptability, while the latter significantly reduces production efficiency.

[0003] Currently, the automation level of die-cutting production lines faces significant bottlenecks. While manual loading is inexpensive, it suffers from low operational efficiency, poor positioning accuracy, and safety hazards, making it unsuitable for continuous production. Using robotic arms for loading and unloading can improve efficiency, but their complex structures require independent drive systems and additional workspace, significantly increasing equipment costs and floor space, thus placing an economic burden on small and medium-sized enterprises. Furthermore, existing automation solutions struggle to coordinate the mold opening and closing strokes with the loading and unloading actions: robotic arms can only operate after the mold is completely separated, resulting in long idle travel times and hindering production efficiency improvements. Utility Model Content

[0005] This utility model provides a burr-free edge cutting system, including mold I, mold II, die-cutting drive mechanism and support;

[0006] The die-cutting drive mechanism includes a linear drive mechanism I, a moving rod, and a linear drive mechanism II. The linear drive mechanism I is mounted on a support, the moving rod is mounted on the output end I of the linear drive mechanism I, and the die I is mounted on the end of the moving rod.

[0007] Mold II is mounted on a support, and mold I and mold II are arranged opposite to each other. Linear drive mechanism I can drive mold I to move closer to or away from mold II.

[0021] The loading and unloading mechanism includes a linear drive mechanism IV mounted on a support and a workpiece fixture to be die-cut and a die-cut workpiece fixture mounted on the output end IV of the linear drive mechanism IV.

[0023] Furthermore, the distance between the moving path of the workpiece fixture to be die-cut and the output end II is close to the distance between the moving path of the die-cut workpiece fixture and the output end II.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0039] As attached Figure 1 - Appendix Figure 8 As shown, this utility model provides a burr-free edge cutting system, including a mold I1, a mold II2, a die-cutting drive mechanism 3 and a support 4, wherein the mold I1 can be an upper mold or a lower mold, and the mold II2 can be either a lower mold or an upper mold. When the mold I1 is the upper mold, the mold II2 is the lower mold, and vice versa.

[0040] The die-cutting drive mechanism 3 includes a linear drive mechanism I 31, a moving rod 32, and a linear drive mechanism II 33. The linear drive mechanism I 31 is mounted on the support 4, the moving rod 32 is mounted on the output end I 311 of the linear drive mechanism I 31, and the mold I 1 is mounted on the end of the moving rod 32. Preferably, a sleeve 36 is mounted on the support 4, the linear drive mechanism I 31 is fixed to one end of the sleeve 36, and the moving rod 32 is slidably mounted inside the sleeve 36.

[0041] Mold II2 is mounted on support 4. Mold I1 and mold II2 are arranged opposite to each other. Linear drive mechanism I31 can drive mold I1 to move closer to or away from mold II2. When mold I1 moves closer to mold II2, die cutting is performed; when mold I1 moves away from mold II2, unloading is performed.

[0042] The mold I1 is provided with through holes 11 that extend through both ends of the moving direction;

[0043] Linear drive mechanism II 33 is mounted on the moving rod 32. Linear drive mechanism II 33 moves in tandem with the moving rod 32. An electromagnet 34 is provided at the output end II 331 of linear drive mechanism II 33. The electromagnet 34 is used to extend out of the workpiece in the through hole 11, that is, the output end II 331 can slide within the through hole 11. The workpieces are divided into workpieces to be die-cut 7 and die-cut workpieces 8 according to their state.

[0044] The burr-free edge cutting system provided by this utility model includes a linear drive mechanism I 31 and a moving rod 32 in the die-cutting drive mechanism 3, which can realize the die-cutting stroke and reset stroke of the mold I 1. The linear drive mechanism II 33, the electromagnet 34 and the through hole 11 can be used to realize the loading of the workpiece 7 to be die-cut and the unloading of the die-cut workpiece 8.

[0045] The specific loading process is as follows: Linear drive mechanism IV 61 drives the workpiece clamp 62 and the workpiece 7 on the workpiece clamp 62 to move to the moving path of output end I 311. Linear drive mechanism II 33 drives electromagnet 34 to extend from through hole 11 (at this time, linear drive mechanism I 31 can drive moving rod 32 and mold I 1 to move closer to workpiece clamp 62 to reduce the stroke requirement of linear drive mechanism II 33). Electromagnet 34 is energized until it picks up workpiece 7. Then, linear drive mechanism IV 61 drives workpiece clamp 62 to leave the moving path of output end I 311. Linear drive mechanism I 31 continues to move, driving moving rod 32, mold I 1, linear drive mechanism II 33, electromagnet 34 and workpiece 7 to move towards mold II 2. Before mold I1 and mold II2 are connected, electromagnet 34 transports the workpiece 7 to be die-cut onto mold II2 (mounting hole 21). Then, linear drive mechanism II33 drives electromagnet 34 to retract into through hole 11, completing the loading process. During die-cutting, linear drive mechanism I31 only needs to sequentially drive moving rod 32 and mold I1 toward mold II2 to perform die-cutting on the die-cutting position on the workpiece 7.

[0046] The specific unloading process is as follows: After die-cutting, linear drive mechanism II 33 drives electromagnet 34 to extend from through hole 11 and pick up the end of the die-cut workpiece 8. Linear drive mechanism I 31 resets, driving moving rod 32, mold I 1, linear drive mechanism II 33, electromagnet 34, and die-cut workpiece 8 to move a certain distance. At this time, linear drive mechanism IV 61 drives die-cut workpiece fixture 63 to move onto the moving path of output end I 311. Linear drive mechanism I 31 or linear drive mechanism II 33 extends towards die-cut workpiece fixture 63, causing die-cut workpiece 8 to enter die-cut workpiece fixture 63, and electromagnet 34 is de-energized. Linear drive mechanism IV 61 drives die-cut workpiece fixture 63 and die-cut workpiece 8 to reset. The unloading of die-cut workpiece 8 is completed. At the same time, preparations are made for the next loading. Die-cutting can then be repeated cyclically.

[0047] The burr-free edge-cutting system provided by this utility model makes reasonable use of the axial space of the mold for workpiece loading and unloading. Compared with existing manual loading, it is more efficient and saves manpower. Compared with existing robotic loading and unloading, it can significantly reduce costs and ensure a compact overall structure. Moreover, the loading and unloading process can utilize the mold closing and opening strokes of mold I1 and mold II2, thereby ensuring overall efficiency.

[0048] In one embodiment, reference Figure 5 and Figure 6 The movable rod 32 is provided with a mounting groove 321, and a sliding hole 322 penetrating to the mold I1 is provided on the side of the mounting groove 321 near the end of the movable rod 32.

[0049] The linear drive mechanism II 33 is mounted on the mounting slot 321, and the output end II 331 is slidably mounted in the sliding hole 322. In this embodiment, the linear drive mechanism II 33 is integrated into the moving rod 32, which can further ensure the compact structure, and at the same time, the linear drive mechanism II 33 can move by utilizing the moving stroke of the moving rod 32, reducing the stroke requirement of the linear drive mechanism II 33.

[0050] In one embodiment, the moving rod 32, output end I 311, and output end II 331 are coaxially arranged. This arrangement allows the workpiece 7 to be die-cut or the already die-cut workpiece 8 picked up by the electromagnet 34 to be directly coaxial with the through hole 11 of mold I1 and the mounting hole 21 of mold II2, without the need for movement in other directions to dock with the workpiece 7 to be die-cut or the already die-cut workpiece 8, thus simplifying the docking process.

[0051] In one embodiment, an mounting sleeve 35 is provided between the mold I1 and the moving rod 32. The mold I1 is detachably mounted on the mounting sleeve 35, which facilitates the disassembly, assembly, and replacement of the mold I1.

[0052] In one embodiment, the side wall of the mounting sleeve 35 is provided with a chip discharge port 351 that communicates with the through hole 11, so as to facilitate the removal of debris that enters the mold I1.

[0053] In one preferred embodiment, mold I1 is an upper mold, and the end of mold I1 is provided with a cutting edge groove 12;

[0054] Mold II2 is the lower mold, and mold II2 is provided with mounting holes 21 for accommodating the workpiece 7 to be die-cut.

[0055] Taking a bolt as an example, the screw is used to be embedded in the mounting hole 21, and the screw head is placed on the end face of the mounting hole 21. At this time, the cutting die slot 12 can be die-cut into the required shape, such as a regular hexagon, as it moves toward the screw head during the die-cutting process.

[0056] In one embodiment, a die-cutting corresponding slot 22 is provided opposite to the trimming die slot 12, and the slot sizes of the die-cutting corresponding slot 22 and the trimming die slot 12 are the same. By providing the die-cutting corresponding slot 22, during the die-cutting process, the end of the screw head closest to the screw can be die-cut by the die-cutting corresponding slot 22, while the remaining part is die-cut by the trimming die slot 12. This effectively solves the problem of burrs forming under the trimmed edge, thereby achieving burr-free trimming.

[0057] In one embodiment, the mounting hole 21 is a through hole;

[0058] This burr-free edge trimming system also includes a linear drive mechanism Ⅲ5 fixedly mounted on the bracket 4. The output end Ⅲ51 of the linear drive mechanism Ⅲ5 is slidably mounted on the mounting hole 21. The linear drive mechanism Ⅲ5 is used to push the die-cut workpiece 8 out of the mounting hole 21, avoiding the problem of the die-cut workpiece 8 getting stuck in the mounting hole 21, which would prevent the electromagnet 34 from pulling the die-cut workpiece 8 out of the mounting hole 21.

[0059] In one embodiment, the invention further includes a loading and unloading mechanism 6;

[0060] The loading and unloading mechanism 6 includes a linear drive mechanism Ⅳ61 mounted on the bracket 4 and a workpiece clamp 62 to be die-cut and a workpiece clamp 63 already die-cut mounted on the output end Ⅳ611 of the linear drive mechanism Ⅳ61.

[0061] Linear drive mechanism Ⅳ61 is used to drive the workpiece fixture 62 to be die-cut and the workpiece fixture 63 to move onto the movement path of output end Ⅱ331. It should be noted that the structure of the workpiece fixture 62 to be die-cut and the workpiece fixture 63 can be a locking hole for engaging the workpiece, or it can be any other structure that can connect and separate from the workpiece.

[0062] In one embodiment, the distance between the moving path of the workpiece fixture 62 to be die-cut and the output end II 331 is close to the distance between the moving path of the die-cut workpiece fixture 63 and the output end II 331. This arrangement ensures that during the loading process, the die-cut workpiece fixture 63 does not enter the moving path of the output end II 331, thus not interfering with the docking between the electromagnet 34 and the workpiece fixture 62 to be die-cut. During the unloading process, when the electromagnet 34 enters between the die-cut workpiece fixture 63 and the linear drive mechanism I 31, the workpiece fixture 62 to be die-cut will not interfere with the docking between the electromagnet 34 and the die-cut workpiece fixture 63.

[0063] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
