[0002] In the traditional LED bracket manufacturing process, the connection structure before stamping is usually assembled by machinery or automated equipment. Specifically, individual bracket components such as the support part, the connection part and the cutting part are connected by mechanical bonding or temporary welding to form a whole. The main function of this connection structure is to maintain the position stability of the components and the integrity of the overall structure during the stamping process to facilitate subsequent processing and assembly.

[0003] Reference Manual Attached Figure 3 In the prior art, when the LED bracket stamping connection structure is blanking on one side, the cutting portion 2 only receives the extrusion force from one side and its size is smaller than the connecting portion 3, which leads to an unbalanced force. Therefore, the cutting portion 2 tends to move in the opposite direction, i.e., the direction of the connecting portion 3, when subjected to force, and splashing may occur, which not only affects the production efficiency of the LED bracket, but also may damage the quality and consistency of the final product.

[0026] In order to make the content of the utility model more clearly understood, the utility model is further described below based on specific embodiments in combination with the accompanying drawings.

[0027] It should be noted that the terms "center", "upper", "lower", "front", "back", "left", "right", "inner", "outer" and the like used herein to indicate directions or positional relationships are based on directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Unless otherwise specified, "plurality" means two or more.

[0028] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0029] like Figures 1 to 4 As shown, the embodiment of the present application provides a punching connection structure of an LED bracket to prevent waste from jumping, comprising a support portion 1, a cutting portion 2 and a connecting portion 3, wherein the cutting portion 2 is connected to the connecting portion 3, and the connecting portion 3 is connected to the support portion 1, and the connecting portion 3 is used to connect the LED brackets on both sides, and the support portion 1 is used to support the LED brackets on both sides before the hardware punching process is performed, and the width of the cutting portion 2 away from the connecting portion 3 is greater than the width of the side close to the connecting portion 3;

[0030] When the LED bracket is undergoing a metal punching process, the cutting portion 2 is suspended in the air, and the cutting portion 2 is squeezed by the supporting portion 1 and then cut off and falls vertically relative to the ground.

[0031] The utility model ensures that waste materials will not move toward the connecting part or into the LED bracket during the stamping process by designing the cutting part to have a wider side away from the connecting part than the side close to the connecting part, thereby significantly reducing damage to the LED bracket caused by waste material splashing, improving the production efficiency of the LED bracket, and ensuring the quality and consistency of the final product.

[0032] In addition, since the cutting part can make the waste material fall directly after cutting, the accumulation of waste material on the mold or product surface is avoided, thereby reducing the cleaning work and improving production efficiency.

[0033] Optionally, the cutting portion 2 is perpendicular to both sides of the connecting portion 3 and is in an R-angled gourd shape.

[0034] The utility model adopts the R-angle gourd-shaped cutting part, which effectively guides the waste to fall directly vertically when being squeezed, instead of splashing toward the connecting part, thereby reducing the impact of the waste on the mold surface, reducing the wear and potential damage of the mold, and improving the service life of the mold and production safety.

[0035] As a preferred solution but not a limitation, in this embodiment, in addition to using the R-angle gourd shape, several other shapes can also be considered as the design of the cutting portion to optimize the stamping process and prevent waste from splashing:

[0036] 1. Oval design: The oval cutting part design can provide smooth edges, thereby reducing the resistance of the waste during the stamping process and helping the waste to fall more smoothly. The two ends of the oval can be more compact, thereby effectively limiting the possibility of the waste moving to the side.

[0037] 2. Design with guiding slopes: Add slopes to the cutting part, which can guide the waste to fall directly downward like a funnel. The angle of the slope can be optimized according to the specific punching pressure and waste characteristics to ensure the smooth movement of the waste.

[0038] 3. Wave-shaped design: The wave-shaped edge design can create multiple pressure points during stamping, which helps to interrupt the continuity of the waste, making it easier to separate at specific breakpoints and fall smoothly.

[0039] 4. Triangular or conical design: The triangular or conical cutting part can provide a sharp angle, which helps to accurately cut the material during the stamping process. The sharp angle is also conducive to controlling the direction of the waste and moving it in the predetermined direction.

[0040] 5. Design with built-in grooves: A series of grooves are designed inside the cutting part, which can serve as waste guide paths to help waste collect and fall in a specific direction, reducing its random splashing on the mold surface.

[0041] As a preferred solution but not a limitation, the cutting part of the mold is also hardened (carbonitriding, chrome plating or titanium plating) to improve its hardness and wear resistance, reduce wear and make the stamping process smoother.

[0042] Optionally, the cutting portion 2 includes a stamping body 21, a first guide angle 22 and a second guide angle 23, wherein the first guide angle 22 and the second guide angle 23 are located on both sides of the stamping body 21, and the curvature of the first guide angle 22 and the second guide angle 23 away from the connecting portion 3 is greater than the curvature of the first guide angle 22 and the second guide angle 23 close to the connecting portion 3.

[0043] In this embodiment, the first guide angle and the second guide angle have a greater arc away from the connection part than the arc close to the connection part, which can more effectively guide the waste to flow smoothly and reduce the situation where the waste is splashed in undesirable directions during the stamping process, thereby protecting the mold from damage and improving the overall quality of the product.

[0044] In addition, this design helps reduce the extrusion and tensile forces during the stamping process, avoiding material breakage or deformation, ensuring higher production efficiency and better product consistency.

[0045] As a preferred solution rather than a limitation, an adjustable guide angle is introduced. The introduction of the adjustable guide angle can adjust the curvature of the guide angle according to different production requirements, making it more suitable for materials of different thicknesses or hardnesses, thereby enhancing the applicability and flexibility of the mold.

[0046] Optionally, the cutting portion 2 further includes a first buffer corner 24 and a second buffer corner 25 , and the first buffer corner 24 and the second buffer corner 25 are located at two sides of the cutting portion 2 .

[0047] In this embodiment, the cutting portion includes a first buffer angle and a second buffer angle, which greatly enhances the function of the mold. The design of the first buffer angle and the second buffer angle optimizes the distribution of force during the stamping process, which not only reduces the stress concentration that may be generated by the material at the punching edge, but also reduces the risk of material breakage and deformation, which is conducive to maintaining the integrity and dimensional accuracy of the stamped material.

[0048] As a preferred solution rather than a limitation, the first buffer angle and the second buffer angle are designed to be adjustable. By making the buffer angle adjustable, the size and angle of the buffer angle can be adjusted according to different material and thickness requirements to adapt to various stamping conditions and requirements.

[0049] Optionally, the connecting portion 3 includes a connecting body 31 and a third guide angle 32 , the third guide angle 32 is in an arc shape, and the third guide angle 32 is located at the connection between the connecting portion 3 and the supporting portion 1 .

[0050] In this embodiment, the connecting part includes a connecting body and a circular arc-shaped third guide angle, which is located at the connection between the connecting part and the supporting part. The circular arc-shaped design of the third guide angle optimizes the entire stamping process, allows the material to pass through the connection point smoothly, reduces the friction and loss of the material when passing through the joint, and thus reduces the risk of material breakage.

[0051] In addition, the arc-shaped guide angle can improve the fluidity of the material, enhance the stamping accuracy and surface cleanliness, and ensure the consistency of product quality and the stability of the manufacturing process.

[0052] As a preferred solution but not a limitation, a material with higher hardness and better wear resistance such as hardened steel or tungsten carbide can be selected, and electroplating or coating technology can be applied to increase the sliding properties and wear resistance of its surface.

[0053] Optionally, a hollow hole 11 is further provided in the middle of the support portion 1 .

[0054] In this embodiment, the design of the hollow hole can reduce the amount of material used, thereby directly reducing the production cost. By reducing material consumption, it not only saves resources but also reduces the weight of the entire mold and simplifies the manufacturing and transportation process.

[0055] Secondly, the hollow holes help improve the blanking process, and waste materials can be removed more easily through these holes to avoid accumulation in the mold, thereby maintaining a clean working environment and improving production efficiency.

[0056] In addition, the hollow holes can also serve as cooling channels to help accelerate the heat dissipation during the stamping process and protect the mold from overheating damage.

[0057] As a preferred solution but not a limitation, the support part is made of a high thermal conductivity material to enhance the heat dissipation performance of the hollow hole, thereby further improving the stamping efficiency and the life of the mold.

[0058] Optionally, the hollow hole 11 is a rounded rectangle.

[0059] In this embodiment, the rounded corners can reduce the stress concentration generated by the material during the stamping process, reduce the risk of cracks and breakage, and ensure the overall quality of the product.

[0060] Optionally, the supporting portion 1 and the cutting portion 2 are made of metal.

[0061] In this embodiment, the application of metal material improves the structural strength and durability of the entire mold, enabling it to withstand high-speed and high-pressure stamping operations. The high wear resistance of the metal ensures that the mold maintains good performance during long-term use, reduces wear and failure rate, thereby reducing maintenance costs and downtime.

[0062] Optionally, the connecting portion 3 is made of plastic.

[0063] In this embodiment, the plastic material generally has good corrosion resistance and insulation properties, which can effectively prevent metal corrosion and electrical failures that may occur during the stamping process, thereby improving the safety and reliability of the mold.

[0064] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
