AI Technical Summary
Existing copper sleeve flanging dies are prone to displacement during the copper sleeve flanging process, resulting in substandard flanging angles. This is especially true when processing thin-walled copper sleeves, where material flow is more pronounced. Traditional fixing methods are insufficient to effectively constrain micro-displacements, affecting product qualification rate and processing efficiency.
The limiting component includes a limiting post and a retaining ball. The retaining ball slides by being squeezed by the inner wall of the copper sleeve, which drives the limiting post to compress the spring and release the elastic force to achieve the limiting. Combined with the pressing block and hook structure in the disassembly component, the upper mold can be quickly replaced and fixed.
It improves the stability and applicability of the flanging die, ensures the accuracy of the flanging angle, simplifies the process of changing the upper die, and improves production efficiency and product quality.

Figure 1 Figure 5 The lower pressing plate 7 is slidingly connected to the outer wall of the guide column 12 to ensure the vertical accuracy and stability of the pressing process. The top of the guide column 12 is fixedly connected to the bottom of the top plate 3 to provide structural support and maintain the fixed position of the guide column 12. The disassembly assembly includes a hollow frame 14 for accommodating sliding components and providing installation reference. The top of the hollow frame 14 is fixedly connected to the bottom of the lower pressing plate 7 to integrate the disassembly mechanism with the lower pressing plate 7. The hollow frame 14 is slidingly connected with a pressing block 17 inside for manual operation to trigger the disassembly action. The pressing block 17 is fixedly connected with a sliding column 19 on one side for transmitting pressing force and driving the limit handle 21 to move.
