自由锻锤或模锻锤,都是冶金工厂或机器制造厂的主要生产设备。由于近代机器制造工业迅速的发展,许多机器中的大小零件都要在锻锤下完成金属的塑性变形工作,以提高机器零件的机械性能,延长零件的使用寿命;因此锻锤在冶金工厂与机器制造厂中已日见广泛地被应用着。目前所见的锻锤虽然很多,但它们的落下部份——锤头与拉杆的结构,常兄的只有固定接合一种。这种结构在实际使用中,又常常发现某些地方不大合理、不是拉杆容易折断,就是制造或安装困难,往往给国家造成不应有的损失。
Free forging hammers or die forging hammers are the main production equipment of metallurgical plants or machine manufacturers. Due to the rapid development of the modern machine manufacturing industry, many parts of the machine are required to complete the plastic deformation of the metal under the forging hammer in order to improve the mechanical properties of the machine parts and extend the service life of the parts; therefore, the forging hammer in the metallurgical plant and the machine It has been widely used in manufacturing factories. Although there are many forging hammers that are currently seen, the falling parts of them—the structure of the hammerhead and the tie rods—are only fixed joints of the everlasting brothers. In actual use of this structure, it is often found that certain places are not reasonable, and it is not easy for the tie rod to break. It is difficult to manufacture or install, and it often causes undue losses to the country.
