Description

Technical Field

[0001] This utility model relates to the field of riveting equipment, specifically to a hot melt riveting device. Background Technology

[0002] Plastic parts are typically attached to aluminum alloy shells using snap-fit ​​screws, but these two methods are cumbersome to install and prone to detachment after installation. Therefore, some products use hot riveting to connect them. The specific method involves pre-setting a high connecting post on the plastic part, which passes through the connecting hole on the aluminum alloy shell. A heating head melts the upper part of the connecting post and expands it by extrusion, thus achieving the hot riveting connection of the plastic part. However, existing hot riveting equipment is usually a single-head handheld riveting system, where workers manually heat and rivet multiple connecting posts, resulting in low processing efficiency and poor quality stability.
