The invention provides a light-weight truck front bumper and a manufacturing method thereof.The light-weight truck front bumper comprises an injection molding part, a die-casting aluminum part and a stamping and welding part, the injection molding part is manufactured through an injection molding method and made of high-strength plastic, and the die-casting aluminum part is made of high-strength plastic; the injection molding part comprises a left side bumper outer plate and a right side bumper outer plate, and connecting piece mounting structures are arranged in the left side bumper outer plate and the right side bumper outer plate and used for mounting connecting pieces; the die-casting aluminum part is of a connecting support structure and is manufactured through the process that connecting pieces are connected and die-casting aluminum parts are combined. The stamping and welding part comprises a license plate decoration inner and outer plate welding assembly and a bumper lower cross beam inner and outer plate welding assembly, and the stamping and welding part is in lap joint with a plastic part and a die-casting aluminum part structure through a welding connecting piece. According to the light-weight truck front bumper, not only is the mass of the light-weight truck front bumper reduced, but also the characteristic that the light-weight truck front bumper absorbs collision energy is further utilized, and the safety is greatly improved.
本发明提供了一种轻量化卡车前保险杠及其制造方法,所述轻量化卡车前保险杠包括注塑件部分、压铸铝件部分和冲焊部分,所述注塑件部分采用注射成型法制造,注塑件部分为用高强度塑料材质,注塑件部分包括左侧保险杠外板和右侧保险杠外板,左侧保险杠外板和右侧保险杠外板均内设有连接件安装结构,用于安装连接件;压铸铝件部分为连接支架结构,采用连接件连接与压铸铝件相结合的工艺制造;冲焊部分包括牌照装饰内外板焊接总成与保险杠下横梁内外板焊接总成,冲焊部分通过焊接连接件搭接塑料件与压铸铝件结构。轻量化卡车前保险杠不仅仅减轻了使用轻量化卡车前保险杠质量,还进一步利用其吸收碰撞能量的特点,对安全性起到很大的改善。
