The main forming equipment for processing the blank of the handle die forging is the counter hammer. The running-in gap between the upper and lower hammer heads is large during the working process of the equipment, which is easy to cause the forging to be out of shape. Therefore, the main shaft diameter and the connecting rod diameter are not easy to be too large to lose weight during the design of the mold cavity. Due to the characteristics of the equipment, it is impossible to install an ejector device in the mold cavity, so the draft angle of the forging cannot be further reduced.

If the blank allowance is large and the distribution of the allowance is unreasonable, the raw materials used for processing the shank die forgings will increase, and the machining cost will increase. On the contrary, the small allowance will increase the processing scrap rate of the shank die forgings.

With the development of production, the number of handle die forgings processed by Wuxi Tianrun keeps increasing, and its economic benefits will be greater.
