[China Aluminum Industry Network] Aluminum alloy has advantages of low density, high strength, good toughness and corrosion resistance, etc. It is widely used as a structural material in the aerospace industry. At the same time, it is actively being developed as an advanced automobile material and used in high-grade cars. engine.
Casting process is the main preparation method of traditional aluminum alloys, but it has been difficult to meet the needs of preparing high-performance aluminum alloys. At the front, the traditional process has been difficult to further improve the strength, plasticity, stiffness, heat resistance and corrosion resistance; Second, in the pursuit of high performance, the cost of the casting process is rapidly increasing due to the increase in equipment and yield; As the alloy content increases, the plasticity tends to decrease, so that the subsequent pressure processing costs increase and the yield decreases.
Therefore, the high cost of production has greatly increased the use threshold of advanced aluminum alloys and seriously affected the development of the overall market scale. In these aspects, the injection molding process has the dual advantages of performance and comprehensive cost, which can reduce the use of advanced aluminum alloy threshold, and can further improve the performance, to achieve aluminum in a certain range of steel, so that the rapid development of advanced aluminum alloy The market, in turn, promotes the injection molding process to gain economies of scale. Therefore, the spray forming process will become the main production process of advanced aluminum alloys.
Folding knife, a kind of knife, can be folded. The folding knife is mainly connected with a knife body which can be rotated into by a pivot assembly at the front end of the handle. The knife body is provided with a safety buckle relative to the side of the knife body, and an elastic strip relative to the back end of the knife body. The back end of the knife body is provided with a stop part and a stop concave part which can be butted by the elastic strip, and the safety buckle has a tilted elastic buckle part, The elastic strip is arranged in the holding chamber of the handle, one end of which is fixed, and the other end of which is connected with the stop part of the tool body, so as to provide the thrust to assist the rotation of the handle when the tool body is rotated out of the handle, In addition to the simple semi-automatic operation mode of turning out and positioning by using the elastic auxiliary push knife body, the overall thickness of the folding knife is reduced by the refined and simplified structural design, which is convenient for the collection and carrying of the folding knife and makes the operation of the folding knife easier.
