Description

Technical Field

[0001] The invention belongs to the technical field of titanium electrode fast blanking, assembly and stacking, and in particular relates to a turning blank assembly device and a turning blank assembly method for circular electrode blocks. Background Art

[0002] Titanium electrode blocks are a product made by pressing titanium sponge with a press, and are generally divided into two types: lantern-shaped and round. The lantern-shaped electrode blocks are produced due to the tonnage limitation of the press. In order to ensure that the density of each part of the electrode block meets the requirements, the electrode blocks can only be pressed into a lantern shape first, and then multiple lantern-shaped blocks are combined into a round electrode block for smelting. With the continuous innovation of large-tonnage die forging press technology, the use of new presses can complete the overall pressing of round electrode blocks, and the density of each part of the electrode block meets the process requirements. Therefore, in the titanium industry, the production of lantern-shaped electrode blocks has gradually developed into round electrode blocks. However, the existing electrode block blanking and assembly equipment cannot operate on round electrode blocks, and cannot complete the overall rapid blanking and assembly of round electrode blocks.

[0003] To solve this problem, most manufacturers choose to use manual lifting for semi-automatic production, which results in a large waste of human resources and seriously restricts the production efficiency of electrode blocks. In addition to this method, some manufacturers use manipulators to assist in assembly, stacking vertically first and then flipping the whole body to complete the blanking and assembly of electrode blocks. The overall process is complex, the maintenance cost is extremely high, and the assembly effect is not obvious. At the same time, during the operation, it is easy to cause problems such as edge breakage and corner loss of electrode blocks, which affects the yield of electrode block production and causes a lot of economic waste. It not only restricts the production capacity of electrode blocks, but also increases production costs. Summary of the invention
