AI Technical Summary

Technical Problem

Existing soundproof foams in the automotive industry cannot be pre-pressed during the flattening process, resulting in the foam being unable to be evenly distributed during the initial extrusion, which can easily cause excessive compression in some areas, waste materials and damage the foam structure.

Method used

A lightweight automobile sound insulation foam flattening device is designed, including a processing table, a molded shell, a flattening cylinder, a U-shaped frame, a spring, a slider, a linkage plate, a connecting column and a press plate. By starting the flat cylinder, the U-shaped frame drives the pressure plate to move downward, the pressure plate contacts the foam surface, and the linkage plate rotates with the connecting column, causing the slider to move and the spring compresses, achieving pre-pressure of the foam. Subsequently, the pressing column drives the pressure plate through the connecting column to achieve uniform distribution of the foam and uniform thickness.

Benefits of technology

Through the gradual compression process of pre-pressing and formal extrusion, the internal structure of the foam material is evenly distributed, ensuring uniform thickness after extrusion, reducing internal structural damage, and enhancing the stability and durability of the final sound insulation structure.

[0002] In terms of car life, noise is the enemy of car passengers. In order to protect the environment and reduce the decibel noise value, strict noise emission limits should be formulated according to law. In the automobile manufacturing industry, the degree of noise reduction is getting higher and higher, and manufacturers should also have a higher concept. A material with good sound insulation performance and environmental protection, while meeting the lightweight requirements pursued by the automobile market.

[0003] In the current automobile sound insulation foam flattening process, the sound insulation foam will be directly squeezed and cannot be pre-pressed during the flattening process.

[0020] The sound insulation foam can be placed inside the forming shell 2, and then the flattening cylinder 4 is started, so that the U-shaped frame 5 drives the pressing plate 10 to move downward. When the pressing plate 10 contacts the surface of the sound insulation foam, the pressing plate 10 will be squeezed by the sound insulation foam to rotate the linkage plate 8 and the connecting column 9, so that the sliders 7 on both sides can move in opposite directions, and the spring 6 can be compressed to slow down the downward pressing speed of the pressing plate 10, so that the sound insulation foam can be pre-pressed by the pressing plate 10, and when the flattening cylinder 4 continues to start, the U-shaped frame 5 will drive the pushing column 11 to collide with the connecting column 9. At this time, the pushing column 11 can drive the pressing plate 10 through the connecting column 9 to formally extrude the sound insulation foam, and through this The gradual compression process of pre-pressing and formal extrusion helps to evenly distribute the internal structure of the foam material, ensure the uniformity of the thickness of the sound insulation foam after extrusion, reduce the damage to the internal structure caused by one-time strong extrusion, and enhance the stability and durability of the final sound insulation structure. In addition, during the formal extrusion process of the pressing plate 10, the cutting knife frame 12 will cut the excess part at the edge of the sound insulation foam, eliminating the subsequent manual cutting steps and improving processing efficiency. After the cutting is completed, the U-shaped frame 5 is reset. At this time, the rodless cylinder 13 is started, which can make the collection frame 14 drive the cut sound insulation foam waste to move above the chip groove 15, thereby realizing the automatic collection effect of the waste.

[0025] Furthermore, two slide rails 20 are fixed on the surface of the U-shaped frame 5, and the slider 7 is slidably connected to the surface of the slide rails 20;

[0026] The slide block 7 can slide on the surface of the slide rail 20, thereby preventing the slide block 7 from being separated from the U-shaped frame 5 during movement, thereby improving the stability of the slide block 7 when moving.
