Description

Technical Field

[0001] The present invention relates to the field of vehicle production line supporting tooling, and in particular to a network pipe shearing device and method. Background Art

[0002] Nylon braided mesh tubes can be worn on the outside of special vehicle cab wiring harnesses to play a role in flame retardancy and protection of internal wiring harnesses. Due to the special manufacturing process of nylon braided mesh tubes, using cold cutting to cut them will cause the nylon braided mesh tubes to fall apart. Currently, hot melt knives are mostly used to cut and cut them. Hot melt knives are handheld tools that are electrically heated. When using hot melt knives to cut and cut nylon braided mesh tubes, the blade temperature is high and the operator has a certain risk of burns. In addition, single-piece nylon braided mesh tubes are wrapped in bundles, which are prone to knotting, messiness, and entanglement during use. The mesh tubes need to be manually organized during use, which is time-consuming and labor-intensive.

[0003] A Chinese patent (publication number CN220218682U, publication date 20231222) discloses a cutting device for a wire harness braided mesh tube, which constitutes an automated cutting system from feeding to discharging by setting an unwinding mechanism, a tensioning mechanism, a preheating mechanism, a heating wire cutting mechanism, a clamping mechanism and a discharging mechanism. The braided mesh tube is preheated by the preheating mechanism before cutting, so that when the braided mesh tube enters the cutting station, its own temperature is in a heated ready state, so that when the heating wire cutting mechanism performs radial relative movement cutting on the braided mesh tube, the braided mesh tube in the cutting cut area heats up faster, and the time to reach the critical temperature is greatly shortened. For the cab wiring harness of traditional power special vehicles, different specifications of nylon braided mesh tubes need to be put into accordance with the different outer diameters of each branch wiring harness. The cab wiring harness of new energy special vehicles is more complicated, with a larger number of wiring harnesses, and the demand for the specifications, types and quantities of nylon braided mesh tubes is greater. Therefore, when making the wiring harness, nylon braided mesh tubes of multiple specifications need to be placed on the operating table at the same time, or they need to be replaced frequently, which takes up a large space and is inconvenient to take. Summary of the invention

[0004] The purpose of the present invention is to address the defects of the prior art and provide a network pipe cutting device and method. By installing multiple reel support rods on the reel bracket of the frame and coordinating the space layout of the frame, reels of various specifications can be compactly placed. Operators can conveniently select and use them as needed without frequently searching or replacing them in the huge operating table, which greatly saves operating space and time. Multiple damping sleeves for the network pipe to pass through are arranged on the side of the blade away from the scale. After the network pipe released by each network pipe reel passes through, the damping sleeve provides appropriate resistance, effectively preventing the network pipe from sliding disorderly or quickly retracting, maintaining the stability of the cutting position, and ensuring cutting accuracy and operational safety. Especially when processing network pipes of multiple specifications of complex wiring harnesses, the operating order is maintained and the production layout and process efficiency are optimized.

DETAILED DESCRIPTION

[0026] Example 1

[0027] In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, a network pipe cutting device is provided.

[0028] Special automobile wiring harnesses are complex, and when placing multi-specification nylon braided mesh tubes 10 on a traditional operating table, a large space is occupied and it is inconvenient to access. Based on this, the present embodiment provides a mesh tube shearing device, which adopts a multi-rod design for a reel holder, cooperates with the rack space layout, and compactly arranges reels of various specifications. Operators can conveniently select and use them as needed, optimizing production layout and process efficiency. In addition, there is a risk of scalding, difficult to control precision, and problems with the mesh tube 10 sliding when cutting with a handheld hot melt knife. In the present embodiment, the hot melt knife is fixed to the top plate 6 and precisely positioned with a ruler 7. The operator only needs to move the mesh tube 10, which reduces the probability of scalding and improves cutting accuracy. The damping sleeve 13 controls the resistance of the mesh tube 10 to prevent the displacement interference of the mesh tube 10 during cutting, ensuring safe and efficient operation and improving product consistency and quality stability.

[0029] like Figure 1 and Figure 2 As shown, the network tube cutting device mainly includes a frame, a reel support and a hot melt blade 9. The frame serves as an overall supporting structure and provides a stable framework for the various components of the device. The top plate 6 on the top of the frame is integrated with a scale 7 for accurately measuring the size of the nylon braided network tube 10. The operator can determine the cutting length based on this to ensure cutting accuracy and meet the length requirements of the network tube 10 for different wire harness branches, thereby avoiding the impact of size errors on the wire harness protection effect and assembly quality.

[0030] The reel support is installed inside the frame, and a plurality of reel support rods 4 of cantilever structure are provided on the reel support, which can carry the net pipe reel 3 and install and position it. The net pipe reel 3 is installed on the reel support rod 4 by rotating and cooperating, and the net pipe 10 is gradually released by the rotation of the net pipe reel 3, so that the net pipe reel 3 is smooth and stable when releasing the net pipe 10, ensuring continuous production. It can adapt to the installation of nylon braided net pipe reels 3 of different outer diameters and specifications. Because the wiring harness of special automobiles is complicated, and the specifications of the net pipes 10 adapted to each branch are various, multiple reel support rods 4 can carry and place net pipe reels 3 of multiple specifications, avoiding the time loss and cumbersome operation caused by frequent replacement of the net pipe reel 3.

[0031] The hot melt blade 9 fixed on the top plate 6 is the core cutting component, which can quickly cut the network pipe 10 after being powered on and heated. The multiple damping sleeves 13 on the side of the hot melt blade 9 away from the scale 7 can allow the network pipe 10 to pass through. After the network pipe 10 released by each network pipe reel 3 passes through, the damping sleeve 13 provides appropriate resistance, effectively preventing the network pipe 10 from sliding disorderly or retracting quickly, maintaining the stability of the cutting position, ensuring the cutting accuracy and operation safety, especially when processing network pipes 10 with multiple specifications of complex wire harnesses, meeting the needs of maintaining operation order.

[0032] In this embodiment, the damping sleeve 13 can be made of elastic material, such as rubber or silicone, which has good elasticity and flexibility, and can produce appropriate deformation when the net tube 10 passes through, thereby exerting resistance on the net tube 10. A columnar structure is adopted with a hole in the center, and a damping effect is formed on the net tube 10 in the center hole.

[0033] In order to adapt to the mesh tubes 10 of different specifications, the inner diameter of the damping sleeve 13 can be designed with an adjustable inner diameter, for example, by adjusting the inner diameter size through some elastic buckles or threaded structures. The surface of the damping sleeve 13 can also be provided with textures or protrusions to adjust the friction damping effect. The textures or protrusions can increase the friction with the surface of the mesh tube 10, thereby enhancing the damping effect.

[0034] The damping sleeve 13 works in conjunction with the reel support, guide wheel 12 and other components. Its installation position and structure should ensure that the net tube 10 can be smoothly released from the reel support, and after being accurately guided by the guide wheel 12, it can smoothly pass through the damping sleeve 13, and obtain stable resistance during the passing process to achieve effective control of the net tube 10. The damping sleeve 13 can provide a stable and reliable damping effect, and can prevent the net tube 10 from sliding disorderly or retracting quickly in both static and dynamic conditions, maintain the stability of the cutting position, and thus ensure cutting accuracy and operational safety.

[0035] The entire network tube shearing device is highly integrated, and each component works together to optimize the cutting process. The top plate 6 scale 7 cooperates with the fixed hot melt knife to achieve precise positioning and cutting, meet the strict requirements of the wire harness branch on the length of the network tube 10, reduce the scrap rate, and improve production efficiency and material utilization. The multi-specification network tube reels 3 are arranged in an orderly manner and the network tube 10 is smoothly supplied, reducing the operation pause and switching time, ensuring cutting continuity, and adapting to the rhythm of mass production of automotive wire harnesses.

[0036] The hot melt knife is fixed and set at a safe distance to avoid the risk of burns caused by holding it; the damping sleeve 13 stabilizes the network tube 10 to prevent cutting accidents; the stable support of the frame, the stable rotation of the reel and the reasonable layout of components reduce the possibility of equipment failure and operating errors, ensure long-term stable operation, reduce maintenance costs and downtime, and improve production efficiency and equipment reliability.

[0037] like Figure 1 As shown, the reel support adopts an "I"-shaped structure, which is composed of a precise combination of a support crossbeam 11 and a support longitudinal beam 5. The support crossbeam 11 is firmly fixed to the frame, laying a solid foundation for the entire structure, ensuring that it is stable and does not deform when bearing the weight and operating stress of the network tube reel 3 under complex production environments. Multiple groups of "I"-shaped supports are reasonably spaced vertically along the frame, greatly expanding the reel placement space and quantity, fully meeting the diverse needs of special automotive wiring harnesses for multi-specification nylon braided network tubes 10, and improving the versatility and adaptability of the device.

[0038] The reel support rod 4 is firmly connected to the bracket longitudinal beam 5, and its layout is optimized to make the network reel 3 rotate smoothly and supply the network evenly and continuously, effectively avoiding jamming and entanglement. It meets the characteristics of reels of different specifications and ensures the stable supply of network for each branch harness, improves production efficiency and quality consistency from the root, and lays a solid foundation for high-precision and continuous production of automotive wiring harness manufacturing.

[0039] like Figure 1 and Figure 2 As shown, the introduction of the guide wheel 12 can improve the efficiency and accuracy of the network tube 10 conveying. Multiple guide wheels 12 are installed at precise intervals and correspond one to one with the network tube reel 3 to correct the release path of the network tube 10, ensuring that the released network tube 10 accurately penetrates the damping sleeve 13 and the subsequent cutting process. In the complex multi-specification network tube 10 switching operation, the conveying trajectory is maintained stable, providing core support for the optimization of cutting accuracy and the standardization of operation procedures, greatly reducing the risk of cutting defects and production interruption caused by the deflection and distortion of the network tube 10.

[0040] The guide wheel 12 and the damping sleeve 13 cooperate to construct a precise resistance control mechanism. The guide wheel 12 optimizes the initial conveying trajectory and creates conditions for the precise action of the damping sleeve 13. The damping sleeve 13 accordingly applies moderate resistance to accurately control the conveying speed and stability of the network tube 10, and can maintain the stability of the network tube 10 during cutting, thereby avoiding incision deviation caused by looseness and ensuring a smooth incision with precise size.

[0041] like Figure 1 As shown, the bottom frame 1 and the top plate 6 of the frame are stabilized by multiple support rods 15 to form a frame structure. The frame 1 is equipped with multiple locking rollers 2. After unlocking, it can be flexibly moved to meet the dynamic adjustment requirements of the production line layout; when locked, it can remain stable to ensure cutting accuracy. In the multi-station collaboration scenario of the automotive wiring harness manufacturing workshop, the equipment can be quickly deployed and accurately positioned, the production resource allocation and process connection can be optimized, and the production efficiency and site utilization efficiency can be greatly improved.

[0042] In this embodiment, the frame size is 0.8 m × 0.6 m × 0.8 m, and the material is steel plate. The reel bracket and reel support rod 4 are made of aluminum profiles. The four corners of the aluminum profile are smooth to facilitate the rotation of the mesh tube reel 3. When the mesh tube 10 is transported, it will not scratch the braided mesh tube 10 and is light in weight.

[0043] The two ends of the bracket crossbeam 11 are installed on the support rod 15 of the frame with angle brackets, and two aluminum profile reel support rods 4 are installed on both sides of the bracket longitudinal beam 5 with angle brackets. The spacing between the reel support rods 4 is the diameter of the network management reel 3 disk + 100mm. By adjusting the position of the reel support rods 4, the placement position of network management reels 3 of different specifications can be achieved, and the reel support rods 4 are fixed to achieve the limitation of the network management reel 3.

[0044] like Figure 1 and Figure 2 As shown, a protective plate 8 is installed on the top plate 6, which forms an open groove with the top plate 6, and the hot melt blade 9 is placed therein, reducing the risk of accidental exposure of the blade, effectively preventing operators from being scalded and peripheral equipment from being damaged, and improving operational safety and equipment reliability.

[0045] The switch 14 installed on the top plate 6 is connected to the controller, and the hot melt blade 9 is set to work in coordination with the hot melt blade host to realize the start and stop of the cutting operation. The operator triggers the switch 14 according to the production process and cutting requirements, and the controller responds to adjust the temperature, power and working time of the hot melt blade 9 to meet the cutting requirements. It should be pointed out that when dealing with nylon braided mesh tubes 10 of different materials and specifications and complex wire harness cutting tasks, the operating parameters of the hot melt blade host can also be controlled and adjusted through the controller to match it with the cutting task.

[0046] In this embodiment, the top plate 6 is a double-layer plate, a scale 7 sticker is pasted on the lower plate, and the upper plate covers the scale 7 sticker and the lower plate. The upper plate is a transparent polyester fiber plate with a smooth surface, which can achieve accurate size measurement of the braided mesh tube 10 and avoid hooking and damage to the mesh tube 10. The mesh tube 10 is made of nylon and is formed by weaving. The hot melt blade host can use a handheld hot melt machine, and the blade passes through the top plate 6 and protrudes above the top plate 6.

[0047] Example 2

[0048] In another typical embodiment of the present invention, Figure 1-Figure 2 As shown, a working method of a network management cutting device is provided, using the network management cutting device as in Example 1.

[0049] A working method of a network management shearing device, comprising:

[0050] The net tube reel 3 with the net tube 10 wound around it is installed on the reel support rod 4, and the net tube 10 is released to pass through the damping sleeve 13 and extend to the top of the top plate 6;

[0051] Select the net tube 10 and pull it, measure the required length of the net tube 10 with the ruler 7 and mark it, contact the marked position with the hot melt blade 9 to cut the net tube 10, and take the cut net tube 10.

[0052] The multiple reel support rods 4 on the reel bracket are respectively installed with net pipe reels 3, and net pipes 10 of different specifications are wound on different net pipe reels 3. One end of the net pipe 10 released from different net pipe reels 3 passes through different damping sleeves 13 and extends to the top of the top plate 6.

[0053] Combination Figure 1 and Figure 2 , the working method of the network management shearing device is explained in detail.

[0054] During the preparation stage, the network pipe reel 3 is accurately installed on the reel support rod 4. Network pipe reels 3 of multiple specifications are respectively installed on the reel support rod 4. The released network pipe 10 passes through the guide wheel 12 and then passes through the corresponding damping sleeve 13. The damping characteristics are used to apply appropriate resistance to the network pipe 10 to effectively suppress free sliding, ensuring that in a complex production environment, the initial position of each network pipe 10 is stable and the state is controllable, avoiding production delays and quality fluctuations caused by loose and chaotic network pipes 10, which meets the refined requirements of raw material management in automotive wiring harness manufacturing.

[0055] Select the appropriate specification of the network tube 10 according to the harness, and pull to start the measurement and cutting process. Take the top plate 6 scale 7 as the reference, accurately measure the required length of the network tube 10 and mark it. You can use a marker or other marking methods when marking, and move the marked part to the hot melt blade 9 to complete the cutting. Ensure that the incision is flat and the length is consistent.
