Description

Technical Field

[0001] This invention relates to an integral forming stamping device and stamping method based on ultra-thin aluminum sheets, and particularly to an integral forming stamping device and stamping method based on ultra-thin aluminum sheets, belonging to the field of ultra-thin aluminum sheet processing technology. Background Technology

[0002] The integrated forming stamping device based on ultra-thin aluminum sheets is a "stamping island" integrated system designed specifically for 0.5-1.5mm aluminum alloy sheets. It uses a large-tonnage press in conjunction with precision split molds, automatic loading and unloading, and cleaning and oiling equipment. It addresses the characteristics of aluminum sheets such as high springback, easy cracking, and high surface quality requirements by adopting real-time monitoring and multi-station collaborative control technology to achieve single-time precision forming of complex parts such as automotive body panels, thereby achieving the goal of replacing steel and reducing weight by 30-50%. The radiator mainboard used in automotive radiators is produced by a one-piece stamping device based on ultra-thin aluminum plates. Existing integral forming stamping equipment based on ultra-thin aluminum sheets involves manual or robotic loading and unloading during the stamping process. Manual loading poses a risk of injury to workers during the stamping process, while robotic loading and unloading involves high initial investment costs, relatively long loading and unloading intervals, and generally low processing efficiency. Therefore, there is an urgent need to improve the integral forming stamping equipment and stamping method based on ultra-thin aluminum sheets to solve the above-mentioned problems. Summary of the Invention

During the loading process, place the radiator body blanks side by side under the positioning pins and press them together with the pusher plate. After loading, it is ready for processing. Step 2: Powering on the equipment: Power on the equipment with industrial power and control the upper stamping die to move downwards. During the initial downward movement, there is no blank inside the stamping cavity set inside the lower die. Observe the fit between the upper and lower stamping dies. If the stamping is normal, proceed to the next process. Step 3: Heat sink motherboard processing: The upper stamping die moves upward, synchronously driving the control unit to move upward. During this process, the rotating plate inside the control slot cannot rotate under the limit block, and the fixed plate fixedly connected to the outside of the drive shaft drives the drive shaft to rotate. When the upper stamping die moves to the uppermost position, the drive shaft rotates 90°, at which point one of the positioning slots aligns with the positioning unit. Furthermore, during the 90° rotation of the drive shaft, the lower mold rotates 90°. During the 90° rotation of the lower mold, the heat sink motherboard placed inside the loading unit is transferred to the upper end of the lower mold and stably placed inside the stamping cavity. Then, the upper stamping die moves downward to complete the processing of the radiator body; Step 4: After processing is completed, the equipment repeats steps 2-3 to complete the processing of the next radiator body blank. When the processed radiator body moves to the bottom, the unloading is completed.

[0014] This invention has at least the following beneficial effects: 1. In this invention, automatic feeding and unloading are used for processing, which can effectively avoid the risks associated with manual feeding. The feeding efficiency is high, and it can be achieved simply by rotating the lower die by 90°. This effectively reduces the feeding and unloading interval of stamping, improves processing efficiency, and the overall investment in the equipment is low, thus reducing production costs. 2. In this invention, during the stamping process, by moving the upper stamping die upward, the lower die can be automatically controlled to rotate 90° using the control unit, and the automatic loading and unloading process can be completed without an external power source, making it more stable and precise. 3. In this invention, the positioning unit can further improve the stability of the stamping process. At the same time, the cylinder and the third spring can provide a buffering effect during the stamping process, further improving the stability and quality of the stamping.
