Description
Technical Field
[0001] The utility model relates to a forging and forming device for a refrigerant flow channel plate, belonging to the field of forging. Background Art
[0002] In the traditional forging and forming of aluminum alloy thin plates, sheet materials are used, and appropriate sheet materials are selected according to the shape of the product. The procurement cost of sheet materials is relatively high, and the forging ratio is small, and the performance of the formed parts is average. Open-die forging is generally used, and flash will be generated during open-die forging, which causes great waste of materials. And due to the existence of flash, it needs to be cut and polished, which is easy to damage the workpiece and also affects the appearance. Its disadvantages are as follows:
[0003] (1) The sheet material needs to cover the whole to meet the outer shape of the finished product, so more materials are required, while the bar stock is not. For the S12L refrigerant channel plate, the ratio of bar stock / sheet material is about 0.6 - 0.7. Therefore, the procurement cost of sheet materials is relatively high.
[0004] (2) The forging ratio of using sheet materials is small, the tissue compactness is poor, and the performance of the formed parts is average.
