TECHNICAL FIELD
[0001] The utility model relates to the related technical field of plastic processing and connecting technology, specifically to a double round head plastic hot riveting connection forming device. 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 many 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, the 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 uses 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 uses glue, thread connection or mechanical buckle, etc. However, these connection methods have problems such as insufficient connection strength, inconsistent appearance and complex processing in some application occasions. Especially when connecting parts of different materials, traditional connection methods often fail to achieve ideal connection effect. With the development and progress of related industries, more and more new products require greater pull-off force. The conventional connection technology design cannot meet the requirement of bearing pull-off force after solidification and molding. Therefore, the diameter of the rivet column also needs to be increased. However, after increasing the diameter, the rivet column cannot be uniformly heated during the molding process of the rivet gun, which causes the center part of the rivet column to be unable to quickly soften and form when the surface material is overheated, resulting in poor forming such as pull-off force not meeting the standard, surface unevenness, etc. Therefore, a double round head plastic hot riveting connection forming device is needed.
