Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, and in particular to a hot melt device for processing automotive exterior parts. Background Technology

[0002] Hot fusion is generally used for hot fusion connection. The principle of hot fusion connection is to press the mating surfaces of two PE pipes tightly against a heating tool to heat their flat end faces until they melt. After removing the heating tool, the two molten end faces are pressed together and held under pressure until the joint cools down, so that the two pipe sections are connected as a whole.

[0003] Most automotive exterior parts are currently stamped as a single piece. Some exterior parts need to be assembled after production. These exterior parts need to be connected and assembled into a whole during installation to improve overall integrity. Hot melt welding can make the connection seamless. However, the current hot melt operation is relatively inconvenient to control the two types of exterior parts, resulting in welding difficulties. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems and deficiencies by proposing a hot-melt device for processing automotive exterior parts: starting a support motor drives a heating plate to descend and contact an exterior part, the heating plate heats the exterior part, and after the hydraulic cylinder is activated, the exterior parts are brought into contact with each other. After the melted area of ​​the exterior parts dries, the two exterior parts are fused together, which facilitates docking, assisted welding, operation, and adjustment.
