自由锻锤的立柱发生开裂的现象很多厂都有,其开裂的部位也大致相同,都是首先从导轨槽的下端部开始,然后向两侧延伸。其开裂的原因虽然很多,如铸造缺陷、使用不当、锤头偏击等,但是很多锤子都是在同一个部位开裂,而且裂纹的发展过程也大致相同这一规律就说明此部位的设计是不适当的。 Free forging hammer column cracking phenomenon occurs in many plants have their cracking site is also roughly the same, are the first from the lower end of the guide rail groove, and then extended to both sides. Although the reasons for its cracking a lot, such as casting defects, improper use, such as hammerhead bias, but a lot of hammer cracking in the same place, and the development of cracks is roughly the same rule that this part of the design is not appropriate.
