Description

Technical Field

[0001] The utility model relates to the technical field of plastic hot riveting, in particular to an integrated hot riveting machine. Background Art

[0002] Plastic products are increasingly used in modern industrial manufacturing. Early plastic joining methods, such as glue bonding, suffered from unstable bond strength, potential failure due to environmental factors, and potential environmental and health concerns with glue. Mechanical joining methods, such as screws, can lead to stress concentration, compromising the structural integrity of plastic products and increasing their weight and cost. With the continuous improvement and diversification of plastic material performance, coupled with higher demands for product quality, appearance, and production efficiency, traditional joining methods are increasingly unable to meet these demands. To meet the demand for secure and efficient connections between plastic products, plastic heat riveting technology has emerged. This technology is used to connect parts made of different materials, such as thermosetting and thermoplastic parts, or to connect plastic parts to metal. It utilizes pre-existing plastic rivets, ribs, and ribs on the molded part, which are then pressed through pre-formed holes in the stamped metal sheet structure to achieve localized heating and connection without excessive thermal impact on the entire plastic part, thereby maintaining the material's performance and structural integrity. However, existing heat riveting equipment still has the following shortcomings:

[0003] 1. One piece of equipment tooling is used to weld one component. Multiple components lead to a large number of toolings, which not only takes up space but also increases development costs.

[0004] 2. The number of parts that can be riveted at one time is small, resulting in low production efficiency. Summary of the Invention
