Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of plastic processing and connecting technology, concretely to a plastic hot riveting connection forming device of edge turning and wrapping. BACKGROUND

[0002] With the rapid development of plastic industry, plastic products are more and more widely used in various fields, such as electronic product shell, automobile parts, household appliances, etc. These plastic products often need an efficient and reliable connection method in the assembly process. There are various connection methods for parts in plastic product production, such as screw connection, glue bonding, etc. However, screw connection needs to punch holes on the parts, which not only damages the integrity of the parts, but also may cause stress concentration points, reducing the overall strength of the product. Moreover, the screw connection process is relatively complicated, and the assembly efficiency is low. Although glue bonding can avoid punching, factors such as curing time, bonding strength and environmental resistance of glue will greatly affect the connection quality. Hot riveting connection is a new type of plastic connection technology, which utilizes the thermoplasticity of plastic to deform the plastic rivet column after softening by heating, realizing the connection of parts. This connection method has the advantages of high connection strength and good sealing performance.

[0003] The existing connection between plastic parts often adopts glue, thread connection or mechanical buckle, etc. However, these conventional methods cannot meet the product design derived from the current industry development needs. With the development and progress of related industries, more and more new products need to be riveted in a relatively narrow area and cannot damage the appearance and integrity of the product. The conventional connection technology design needs to drill holes in the corresponding parts for easy assembly and connection, which cannot meet the requirements of this type of product. Therefore, a plastic hot riveting connection forming device of edge turning and wrapping is needed. UTILITY MODEL CONTENTS
