Description

Technical Field

[0001] This utility model relates to the field of plastic riveting and plastic welding technology, specifically to an L-shaped pulse hot riveting head with air cooling. Background Technology

[0002] The pulse-type hot riveting head is an advanced industrial device widely used in precision manufacturing. It utilizes pulse heating technology to achieve rapid and efficient riveting of materials such as plastics and metals, thereby reducing the thermal impact on materials and ensuring product quality. The pulse-type hot riveting head features a compact design and simple operation, making it suitable for riveting various complex and irregularly shaped products. Its unique heating and cooling mechanism not only improves production efficiency but also significantly reduces production costs, making it an indispensable tool in modern manufacturing. Based on actual usage, the existing technology described above has limitations. During production, the hot riveting head is significantly affected by the temperature of the conductive block, making effective and rapid cooling impossible. This deficiency results in an exceptionally long cycle for each hot riveting operation. This extended time directly leads to a substantial decrease in the efficiency of the entire production process, severely impacting production progress and output. Furthermore, some plastic products have limited design space, and the traditional straight hot riveting head, due to its structural characteristics, is prone to interfering with the product itself during up-and-down movements. This not only increases operational difficulty but may also cause unnecessary damage to the product, further affecting product quality and production efficiency. Therefore, based on actual usage, we have improved the aforementioned existing technology. Utility Model Content
