It is understood that the XNZ2430 heavy-duty gantry five-axis hybrid machine tool is the national 863 project undertaken by Qi Er Machine Tool, which is the “high, fine and sharp†major numerical control equipment—the key technology development project of the new large-scale gantry five-axis linkage hybrid machine tool. . Hybrid machines (also known as virtual axis machines) are known as new processing equipment for the 21st century. The utility model overcomes the inherent defects of the traditional tandem structure machine tool, and has the advantages of high modularity, high rigidity, light weight of moving parts, large acceleration, high processing precision, etc., and can realize multi-coordinate linkage numerical control processing.
The main purpose of XNZ2430 new heavy-duty gantry five-axis hybrid machine tool is to meet the key infrastructure equipment needs of China's manufacturing industry, focusing on the processing of large turbine blades. This machine combines the advantages of traditional machine tools and parallel machine tools, with five-axis linkage. Function, able to complete five-sided machining in one setup. It is especially suitable for processing large and long-type parts and Blade parts with complex curved shapes. It is widely used in various industries of the national economy, especially for defense, military, aerospace, power generation equipment, mold manufacturing and other industries. Key precision parts for space surfaces. The machine is equipped with three different functions of the milling head, which expands the machine's performance and processing range.
Taking innovation as the soul of the enterprise, this is the business philosophy of Qi Er Machine Tool in recent years. The advantage and development foundation of the company is also the series development and manufacture of large and heavy CNC machine tools. To this end, they continue to accelerate the pace of technological innovation, in the process of original innovation, integrated innovation, introduction and digestion and innovation, to find the right position and give play to advantages. They insist on the continuous development of CNC milling and boring machines, the development of automatic cold heading machine to industrialization, the development of mechanical presses to large-scale development and the development of general-purpose small machine tools to NC. Each year, more than 40 new products are developed. Since last year, they have independently developed It has introduced 30 kinds of new products with advanced level such as 2400 tons multi-link mechanical press, 10m CNC double-column vertical car, TK6932 super heavy-duty CNC floor milling and boring machine, BMT130 CNC horizontal boring machine and GMC2140 CNC gantry boring and milling machine.
In the past few years, the company has developed 115 kinds of high-end products such as floor milling and boring machining center, CNC gantry boring and milling machine, heavy-duty CNC vertical lathe, large-tonnage CNC multi-link press and high-speed precision multi-station cold forming machine, among which 51 products Fill the domestic gap and win 19 awards including the provincial and above scientific and technological progress awards. The output value of new products averages over 50%, and the numerical control rate of large and heavy products reaches over 60%. More than 90% of new CNC products have reached the international advanced level of similar products.
The successful development of the XNZ2430 new large-scale gantry five-axis linkage hybrid machine tool successfully broke the western technical blockade and provided powerful technical and equipment support for the development of China's defense industry. It marks that China has reached the world's leading level in this field. At the same time, it has also established the position of Qiji Machine Tool in China's heavy-duty CNC machine tool enterprises, demonstrating the solid strength and fruitful results of Qier Machine Tool's independent innovation.
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.
