Description

Technical Field

[0001] The utility model relates to the technical field of foam core material processing, and more specifically, to a foam core material processing tool. Background Art

[0002] Foam parts have excellent specific rigidity and specific strength, and excellent mechanical properties such as compression, tension, shear, and bending. Foam materials as composite sandwich structures can increase the rigidity of parts, reduce the weight of parts, and improve heat and fire resistance. They are widely used in wind power generation, rail transportation, aerospace, and building energy conservation.

[0003] The foam can only be trimmed by hand. Currently, there is no dedicated foam cutting tool. The trimming is difficult and inefficient, and requires a high level of operator skill.

[0004] Chinese patent application number CN202320219945.7 discloses a composite foam core cutting tool, comprising a support, a dial, and a cutting assembly. The dial is mounted on the support and provided with an arc-shaped slot. The cutting assembly comprises a knife holder and a blade mounted on the knife holder. The knife holder is mounted on the dial with a rotating shaft. The knife holder is rotatably connected to the rotating shaft to adjust the cutting angle of the blade. The rotating shaft passes through the arc-shaped slot, allowing the knife holder to slide along the arc-shaped slot with the rotating shaft to adjust the position of the blade. The cutting tool has a simple structure, is easy to operate, has high foam core trimming efficiency, and has low manufacturing cost.

[0005] Then, combined with the drawings in its specification, it can be seen that the blade of the cutting tool is fixed on a rotatable plate. When the length of the blade is less than the thickness of the foam core material, it cannot be completely cut. It is inconvenient to disassemble and replace the blade or directly adjust the length of the blade, which affects the efficiency of the cutting and trimming processing and affects the use effect.
