Hot riveting machine is also called hot riveting machine or hot-melting machine, its full name is hot-melt riveting spot welding machine, which is used to connect forests made of different materials, between thermosetting materials and hot-melting materials To achieve mutual connection, or between plastic and metal. So do you know what the working principle of the welding machine is? Let me introduce to you, the specific content is as follows:

What is the working principle of the hot riveting welding machine
The hot riveting welding machine uses the inherent plastic rivet posts, ribs and vertical ribs reserved on the molded parts, corresponding to the prefabricated holes on the stamping and forming metal plate structure, and the protruding part of the riveting posts (hot posts) on the metal surface After controlled thermal melting and softening, use a special metal forming riveting head to compress, cool, reshape and clamp. The use of specific shaped riveting heads can realize the countersink riveting (flush riveting), hemispherical riveting, and arc flanging riveting of plastic rivets. , Rib rib riveting, mechanical forging, folding and inlaid wrapping, etc., to realize the connection method of mechanical riveting and assembly of materials of different materials, the connection part is not easy to be brittle, beautiful, firm, and well-sealed, so as to achieve the structure Optimize the design, make full use of the combination of the mechanical characteristics of various materials, greatly improve the performance of the overall component, the overall structure is impact resistant, so as to achieve a good fit, especially suitable for long-term mechanical vibration, large environmental temperature and humidity changes, Where the natural environment is extremely harsh.
