This composite material combines the mechanical properties of nylon materials and the thermal conductivity of thermal conductive fillers, making it have broad application prospects in the fields of electronics, aerospace, and automobiles.

[0003] The preparation process of filled high thermal conductivity nylon composite materials generally includes: selecting nylon matrix and thermal conductive filler, dispersing thermal conductive filler into nylon matrix, and preparing composite material products through hot pressing, injection molding and other molding processes. The obtained composite material generally needs to be sheared to meet the size requirements. However, the shearing equipment currently used for filled high thermal conductivity nylon composite materials is generally a fixed structure such as a splint for clamping and fixing the filled high thermal conductivity nylon composite materials, which has low adaptability. When dealing with the fixed shearing of filled high thermal conductivity nylon composite materials with special-shaped structures such as round shapes, it is difficult to provide effective clamping, which affects the shearing effect of filled high thermal conductivity nylon composite materials. For this reason, the present application proposes a shearing device. Utility Model Content
