Description

Technical Field

[0002] During the hot forging process of large circular parts, it is necessary to first punch holes on the heated iron blank through a mold. Since the iron blank is heavy, it is generally transported by a forklift. When the forklift places the heated iron blank on the hot forging table, due to the high temperature in the hot forging workshop, a large amount of water mist will rise on the window of the forklift, which will hinder the forklift master's sight. The forklift master places the blank based on experience, but the position of the iron blank will deviate from the position of the impact hammer, especially when placing the mold for punching the iron blank, which is entirely based on the staff's experience. If the wall thickness of the iron blank is large after punching, the iron blank needs to be restored to a complete state before punching. Since the temperature of the iron blank is high during the hot forging process, it is inconvenient for the staff to measure the iron blank at any time. At the same time, the position of the iron blank needs to be adjusted during the hammering process.
