摘要:

为探究热熔螺母嵌件与塑胶的连接性能,将热熔螺母嵌件连接方式合理应用到三维(3D)打印塑胶壳体中。通过单因素试验分析了嵌件类型、热熔温度和孔洞直径对热熔螺母嵌件与塑胶连接性能的影响,采用田口方法对埋植参数进行优化,得到埋植参数的优化组合,完成了热熔螺母嵌件在3D打印电子产品壳体中的应用实践。结果表明,嵌件的形状影响了其与塑胶的连接性能,各类嵌件的抗拔脱性能排序为:斜纹>网纹>直纹,抗扭转性能排序为:斜纹>直纹>网纹;180~220 ℃范围内,随着热熔温度的升高,嵌件与塑胶的连接性能增强;5.8~6.0 mm范围内,随着孔洞直径的减小,嵌件与塑胶的连接性能增强;埋植参数对嵌件与塑胶连接性能的影响程度为:嵌件类型>孔洞直径>热熔温度,优化埋植参数为:嵌件类型(斜纹)、孔洞直径(5.8 mm)、热熔温度(220 ℃),此参数组合下热熔螺母嵌件的最大拉出力1.22 kN、最大扭矩3.04 N·m,嵌件与塑胶的连接性能最佳。

Abstract:

To explore the connection performance between the hot melt nut inserts and plastics, the connection method of hot melt nut inserts was reasonably applied for 3D⁃printed plastic shells. This paper analyzed the influence of insert type, hot⁃melt temperature, and hole diameter on the connection performance of the hot⁃melt nut insert and plastics through a single⁃factor test, optimized the embedding parameters by the Taguchi methods, obtained the optimal combination of embedding parameters, and completed the practical application verification of the hot⁃melt nut inserts in a 3D⁃printed electronic product shell. The results indicated that the shape of the insert affected its connection performance with plastics. The order of anti pull⁃out performance of various inserts is as follows: twill > mesh > straight, and the order of their anti⁃torsion performance is as follows: twill > straight > mesh. The connection performance between the insert and the plastics increased with an increase in the hot melt temperature ranging from 180 to 220 ℃. Meanwhile, the connection performance between the insert and the plastics increased with a decrease in the hole diameter ranging from 6.0 to 5.8 mm. The order of the influence level of embedding parameters on the connection performance between the insert and plastics is as follows: insert type > hole diameter > hot melt temperature. The optimized embedding parameters were determined to be an insert type of twill, a hole diameter of 5.8 mm, and a hot melt temperature of 220 ℃. Under this parameter combination, the maximum pulling force of the hot melt nut insert was 1.22 kN, and the maximum torque was 3.04 N·m, achieving the best connection performance between the insert and plastics.
