[0002] The radial forging machine is an advanced intelligent precision forging equipment, suitable for forming metal materials with narrow forging temperature range and large deformation resistance. It is a forging equipment for high-precision, axisymmetric parts. Its production line is compactly arranged, with high production efficiency and high degree of automation.

[0003] The radial forging machine is mainly composed of four radially symmetrical hammers for high-frequency forging of blanks. In the actual production process, special forging hammers need to be replaced for production according to different bar temperatures or different bar specifications. At the same time, the radial forging machine has a very high forging frequency, which causes the hammers to wear quickly and also needs to be replaced. Therefore, in the production process of the radial forging machine, the replacement frequency of the hammers is relatively high.

[0004] Currently, there is no special tooling for replacing hammer heads, and most replacement work is done by manpower. However, a hammer head of a large radial forging machine weighs nearly 250 kg, which is very difficult to replace by humans. The replacement time is very long, and there are also major safety hazards. During the operation, once the hammer head falls, it is enough to pose a safety threat to the construction workers.

[0005] The patent of the present invention solves the problem of hammer head replacement well with a simple method and at a relatively low cost, improves the standardization and safety of hammer head replacement, and improves replacement efficiency. Utility Model Content
