Description

Technical Field

[0001] This utility model relates to the field of silicone tube processing technology, and in particular to a cutting machine for processing automotive silicone tubes. Background Technology

[0002] Automotive silicone hoses are flexible pipes made of silicone rubber, primarily used for transporting various fluid media in automobiles, including coolant, lubricating oil, fuel, and air. They possess excellent high-temperature resistance, outstanding chemical inertness, and good anti-aging properties, enabling them to withstand the harsh environment of high temperature, high pressure, vibration, and oil corrosion in the engine compartment for extended periods. Compared to traditional rubber hoses, silicone hoses offer a longer service life and higher reliability, effectively preventing safety hazards such as coolant and fuel leaks caused by pipe aging and rupture. Their flexibility and bendability facilitate installation in the compact engine compartment. With the trend towards lightweight and miniaturized automobiles, silicone hoses, due to their strong weather resistance, environmental friendliness, non-toxicity, and light weight, have become the preferred piping material for key components such as modern automotive cooling systems, turbocharger lines, and fuel evaporation control systems.

[0003] Traditional automotive silicone tube processing and cutting machines lack bidirectional positioning capabilities and cannot adapt to different tube diameters. This causes the silicone tube to shift during cutting due to insecure fixation, resulting in tilted or serrated cuts. At the same time, excessively large clamps compress small-diameter silicone tubes, or excessively small clamps cannot hold large-diameter tubes, both of which lead to out-of-round cut sections, loss of dimensional accuracy, and a surge in scrap rates. The vibration of the silicone tube can also cause sudden changes in cutting resistance, exacerbating the chipping or wear of the cutting blade and reducing the tool's lifespan.

[0004] Therefore, in response to the problems of traditional automotive silicone tube processing and cutting machines lacking bidirectional positioning capability and being unable to adapt to different tube diameters, resulting in loss of dimensional accuracy, a surge in scrap rate, and reduced tool life, a new type of automotive silicone tube processing and cutting machine that can simultaneously and quickly position both sides of the silicone tube and adapt to different sizes can be designed to solve these problems. Utility Model Content

[0013] Preferably, two guide rails are fixedly connected to the processing frame, and the guide rails and the connecting slider are slidably connected. The connecting slider is provided with a slot, and a cutting tool is fixedly connected to the slot.

It is applicable to tubes of various sizes, ensuring that the silicone tube has no axial offset. This avoids the skewed cut or serrated burrs caused by traditional unidirectional fixing, resulting in a smooth cut without deformation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of an automotive silicone tube processing and cutting machine, including a processing frame 1 and a fixed frame 2. The fixed frame 2 is fixedly connected to one side of the processing frame 1, and an adjustment component is fixedly connected to the fixed frame 2. A lower slider 4 is fixedly connected to the output end of the adjustment component. The adjustment component drives the lower slider 4 to perform linear motion. The lower slider 4 is slidably connected to the fixed frame 2. Two first connecting rods 5 are fixedly connected to both sides of the lower slider 4, and a first positioning plate 6 is fixedly connected to the other side of the first connecting rods 5. An upper slider 7 is provided above the lower slider 4 and is slidably connected to the fixed frame 2. Two second connecting rods 8 are fixedly connected to both sides of the upper slider 7, and the other ends of the second connecting rods 8 are fixedly connected to the fixed frame 2. A second positioning plate 9 is fixedly connected to the first connecting rod 5 and the second connecting rod 8. A first rotating plate 10 is fixedly connected to the first connecting rod 5 and the second connecting rod 8. When positioning the silicone tube, the adjusting component outputs power to the lower slider 4, causing the lower slider 4 to slide on the fixed frame 2. This drives the first connecting rods 5 on both sides to move linearly. The first connecting rods 5 drive the first positioning plate 6 to move toward the silicone tube. At the same time, the first rotating plate 10 connects the first connecting rod 5 and the second connecting rod 8. The first connecting rod 5 drives the second connecting rod 8 to move linearly through the first rotating plate 10, causing the upper slider 7 to slide on the fixed frame 2. This achieves the linear movement of the second positioning plate 9 toward the first positioning plate 6, and the silicone tube is synchronously positioned on both sides of the processing frame 1.

[0024] Please see Figures 1-5 In this embodiment, the adjustment assembly includes a hydraulic cylinder 301 and a hydraulic rod 302. The hydraulic cylinder 301 is fixedly connected to the fixed frame 2, and the output end of the hydraulic cylinder 301 is fixedly connected to the hydraulic rod 302. The hydraulic cylinder 301 is used to push the hydraulic rod 302 to perform linear motion. The other end of the hydraulic rod 302 is fixedly connected to the lower slider 4. Pressure is output from the hydraulic cylinder 301 to the hydraulic rod 302, pushing it to perform linear motion and causing the lower slider 4 to slide on the fixed frame 2. A first connecting shaft 11 is rotatably connected to the fixed frame 2. The first connecting shaft 11 and its two sides are... The first rotating plate 10 is fixedly connected, and the two first rotating plates 10 on both sides are connected by the first connecting shaft 11, so that the two first rotating plates 10 move synchronously on the fixed frame 2, so that the positioning mechanisms on both sides move in unison and the structure is more complete. A drive assembly is fixedly connected on the processing frame 1. The output end of the drive assembly is connected to two second connecting shafts 13. The drive assembly is used to drive the second connecting shafts 13 to rotate. The second connecting shafts 13 are rotatably connected to the processing frame 1. The drive assembly outputs power to the two second connecting shafts 13, so that the two second connecting shafts 13 rotate together.

[0025] Please see Figures 2-4In this embodiment, the drive assembly includes a drive motor 1201, a drive shaft 1202, and belts 1203. The drive motor 1201 is fixedly connected to the processing frame 1, and the output end of the drive motor 1201 is fixedly connected to the drive shaft 1202. The drive motor 1201 drives the drive shaft 1202 to rotate. Two belts 1203 are sleeved on the outer side of the drive shaft 1202, and the other end of each belt 1203 is sleeved on a second connecting shaft 13. The drive motor 1201 outputs torque to the drive shaft 1202, causing it to rotate and drive the two outer belts 1203 to rotate together. The belts 1203 drive the second connecting shaft 13 to rotate. A gear 14 is fixedly connected to the second connecting shaft 13, and a limit post 1401 is provided on the gear 14. Two fixed shafts 15 are fixedly connected to the processing frame 1, and a second rotating plate 16 is rotatably connected to each fixed shaft 15. The second rotating plate 16 is provided with a limiting groove 1601. The limiting post 1401 and the limiting groove 1601 are slidably connected. The other end of the second rotating plate 16 is rotatably connected to a connecting slider 17. When the second connecting shaft 13 rotates, it drives the gear 14 to rotate. The two gears 14 mesh and move in opposite directions. The gear 14 drives the limiting post 1401 to rotate, so that the limiting post 1401 slides on the limiting groove 1601, thereby driving the second rotating plate 16 to rotate. The second rotating plate 16 drives the connecting slider 17 to move linearly. Two guide rails 18 are fixedly connected on the processing frame 1. The guide rails 18 and the connecting slider 17 are slidably connected. The connecting slider 17 is provided with a slot 1701. A cutting tool 19 is fixedly connected to the slot 1701. The connecting slider 17 slides on the guide rails 18, driving the cutting tool 19 connected to the slot 1701 to move linearly, thereby realizing the rapid cutting of the silicone tube.

[0026] During operation, the silicone tube is fed onto the processing frame 1. Pressure is output from the hydraulic cylinder 301 to the hydraulic rod 302, causing the hydraulic rod 302 to move linearly. This causes the lower slider 4 to slide on the fixed frame 2, driving the first connecting rods 5 on both sides to move linearly. The first connecting rods 5 drive the first positioning plate 6 towards the silicone tube. Simultaneously, the first rotating plate 10 connects the first connecting rods 5 and 8, and the first connecting shaft 11 connects the two first rotating plates 10, ensuring synchronous movement of the two first rotating plates 10 on the fixed frame 2. This achieves consistent movement of the positioning mechanisms on both sides. Then, the first connecting rod 5, through the first rotating plate 10, drives the second connecting rod 8 to move linearly, causing the upper slider 7 to slide on the fixed frame 2, thus positioning the second positioning plate 9. The machine moves linearly towards the first positioning plate 6, synchronously positioning the silicone tube on both sides of the processing frame 1. Then, the drive motor 1201 outputs torque to the active rotating shaft 1202, causing the active rotating shaft 1202 to rotate. This causes the two outer belts 1203 to rotate together. The belts 1203 drive the second connecting shaft 13 to rotate, which in turn drives the gear 14 to rotate. The two gears 14 mesh and move in opposite directions. The gears 14 drive the limiting post 1401 to rotate, causing the limiting post 1401 to slide on the limiting groove 1601. This causes the second rotating plate 16 to rotate, and the second rotating plate 16 drives the connecting slider 17 to slide on the guide rail 18. This causes the tool 19 connected to the slot 1701 to move linearly, achieving rapid cutting of the silicone tube.

[0027] Through the above steps, the adjustment component, in conjunction with multiple transmission parts, drives the first positioning plate 6 and the second positioning plate 9 on both sides to perform bidirectional positioning of the silicone tube. This method is applicable to tubes of various sizes, ensuring that the silicone tube has no axial offset. It avoids the tilted cut or serrated burrs caused by traditional unidirectional fixing, resulting in a smooth cut without deformation. At the same time, it can also avoid extrusion deformation or fixing failure caused by mismatched fixture dimensions, improve processing accuracy and quality, optimize production efficiency, reduce abnormal tool wear, and reduce equipment maintenance costs. This solves the problems of traditional automotive silicone tube processing and cutting machines lacking bidirectional positioning capability and being unable to adapt to different tube diameters, leading to loss of dimensional accuracy, a surge in scrap rate, and reduced tool life.
