Description

Technical Field

[0001] This utility model relates to the field of carbon paper processing, specifically a new type of furnace inspection carbon paper cutting die. Background Technology

[0002] In the field of carbon paper processing, traditional cutting techniques mainly employ a combination of manual hammering and hand-cutting. Specifically, operators need to prepare a metal mold that matches the desired shape beforehand, place it on the surface of the carbon paper, and repeatedly hammer it to initially shape the paper. Then, scissors or knives are used for secondary trimming along the edges. This method has the following significant drawbacks:

[0003] Inefficient: Manual hammering requires repeated application of force, and subsequent trimming requires layer-by-layer correction, which is time-consuming and difficult to meet the needs of large-scale production.

[0004] Insufficient precision: Manual operation is prone to uneven force or mold misalignment, resulting in rough cutting edges and dimensional deviations, which affect the final performance of carbon paper.

[0005] Material loss: The hammering process can easily cause localized tearing or excessive compression of the carbon paper, leading to a decrease in yield and increased costs;

[0006] High labor intensity: Prolonged use of hammers and scissors can easily lead to operator fatigue and pose occupational health risks. Utility Model Content

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example:

[0023] like Figures 1-2 As shown, this utility model provides a novel furnace carbon paper cutting die.

[0024] The device includes a base 1, an upper die 2, a lower die 3, a blade 4, and a drive mechanism. The lower die 3 is mounted on the base 1, and the upper die 2 is located directly above the lower die 3. The upper surface of the lower die 3 has a first groove 5 that is the same shape as the through hole to be cut, and the lower surface of the upper die 2 has a second groove that is the same shape as the through hole to be cut. The blade 4 is placed in the second groove. Carbon paper is placed on the surface of the lower die 3. The drive mechanism drives the upper die 2 to move downward until the upper die 2 and the lower die 3 gradually close together. The blade 4 cuts the carbon paper on the upper die 2. The first groove 5 and the second groove cooperate to cut the carbon paper with the desired structure.

[0025] The first groove 5 and the second groove form a closed cutting space, ensuring that the blade 4 acts precisely in the vertical direction, avoiding displacement or deformation of the carbon paper, and driving the upper die 2 to descend at a uniform speed, so that the cutting force of the blade 4 on the carbon paper is evenly distributed, reducing the risk of tearing and improving the cutting quality. Compared with the multiple operations of manual hammering and scissor cutting, complex shape cutting can be completed in a single mold closing, greatly improving efficiency.

[0026] Optionally, the driving mechanism includes a pressure rod 6, a rocker arm 7, a fixing ring 8, and a bracket 9. The bracket 9 is mounted on the base 1, and there are two sets of brackets 9. A bolt 10 is provided between the two sets of brackets 9. The side wall of the rocker arm 7 is fixedly connected to the bolt 10. The end of the rocker arm 7 away from the bolt 10 has a mounting hole 11. One end of the pressure rod 6 is fixedly connected to the rocker arm 7 through the mounting hole 11. A fixing ring 8 is provided at the upper end of the upper die 2. The other end of the pressure rod 6 passes through the fixing ring 8 and extends to the left side of the upper die 2. Pressing down the pressure rod 6 drives the upper die 2 to move downward, thereby driving the blade 4 to cut the carbon paper on the upper die 2.

[0027] With bolt 10 as the fulcrum, the rocker arm 7 amplifies the force through leverage when the pressure rod 6 is pressed down. The operator only needs to apply a small amount of pressure to drive the upper mold 2, reducing labor intensity. The two sets of brackets 9 enhance the structural rigidity, prevent the rocker arm 7 from deflecting, and ensure a smooth and shaky mold closing process.

[0028] Optionally, a guide mechanism is provided between the upper die 2 and the lower die 3. The guide mechanism is a guide rod 12. The lower end of the guide rod 12 is disposed on the surface of the lower die 3, and the upper end of the guide rod 12 is disposed through the upper and lower side walls of the upper die 2 and extends to the top of the upper die 2. The upper die 2 moves up and down along the side wall of the guide rod 12.

[0029] The guide rod 12 passes through the upper die 2, restricting its movement to the vertical direction only, thus preventing misalignment during die closing. The guide rod 12 also shares some of the lateral pressure, preventing the upper die 2 from tilting and keeping the blade 4 perpendicular to the carbon paper contact surface, thereby improving cutting accuracy.

[0030] Optionally, the guide rods 12 are configured in at least two sets, with the two sets of guide rods 12 spaced apart.

[0031] The multiple sets of guide rods 12 further enhance the structural stability and load-bearing capacity. The spaced guide rods 12 disperse the lateral force during mold closing, avoiding deformation caused by stress concentration at a single point. The multiple sets of guide rods 12 can support a larger area of ​​upper mold 2, which is suitable for the cutting needs of complex carbon paper structures.

[0032] Optionally, the surface of the pressure rod 6 is provided with anti-slip texture.

[0033] The anti-slip texture on the surface of the pressure bar 6 increases the friction of the contact surface, preventing slippage and operational errors, thus effectively improving safety and optimizing the human-computer interaction experience. Even in wet or oily environments, the anti-slip texture can still provide stable grip, reducing the rate of operational errors. The texture design is ergonomic, reducing hand fatigue.

[0034] Optionally, the fixing ring 8 and the upper mold 2 are integrally formed, or the fixing ring 8 is fixedly welded to the upper surface of the upper mold 2.

[0035] The retaining ring 8 and the upper mold 2 adopt an integrated or welded structure, which improves the durability of the equipment. The integrated molding avoids the risk of weld cracking and extends the service life. The retaining ring 8 is directly integrated into the upper mold 2, reducing the number of parts and lowering maintenance costs.

[0036] In the process of using this application, the carbon paper to be cut is first laid flat on the surface of the lower die 3, ensuring that it corresponds to the position of the first groove 5. The operator presses down on the free end of the pressure rod 6, and the pressure rod 6 pushes the rocker arm 7 to rotate around the fulcrum of the bolt 10 through the mounting hole 11. The lever structure of the rocker arm 7 converts the small displacement of the pressure rod 6 into a large stroke of the upper die 2, driving it to descend along the guide rod 12. The upper die 2 descends vertically along the two sets of guide rods 12, ensuring that the second groove and the first groove 5 are completely overlapped. When the distance between the upper and lower dies 3 is less than the thickness of the carbon paper, the blade 4 cuts into the carbon paper. The cutting is completed as the die closing depth increases. The guide rod 12 shares the lateral force to prevent the blade 4 from deflecting and ensures that the cutting edge is smooth. The pressure rod 6 is released and reset. The cut carbon paper is removed from the lower die 3 due to gravity and can be manually taken out.

[0037] Traditional processes require multiple hammering and trimming steps, while this equipment can complete the cutting of complex shapes in a single closing of the upper and lower die, greatly shortening the processing cycle, improving production efficiency, and operating at high speed, allowing for quick entry into the next processing cycle, making it suitable for high-frequency production needs.

[0038] The dual-groove design ensures that the blade 4 cuts along a fixed trajectory, and the guide mechanism eliminates lateral offset, resulting in smooth, burr-free cutting edges and higher dimensional accuracy. Mechanized operation avoids human error and achieves consistent quality in mass production.

[0039] Precise cutting reduces waste, improves carbon paper utilization, and lowers material costs. A single machine can replace multiple skilled workers, reducing manpower input and corresponding management costs. Modular design facilitates parts replacement, reducing long-term maintenance costs and downtime risks.

[0040] The lever mechanism amplifies the force, significantly reducing the operator's burden; the anti-slip texture design improves operational stability and prevents accidents caused by slipping; the enclosed cutting reduces dust and noise pollution, improving the comfort of the working environment.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
