Description

Technical Field

[0001] The utility model relates to the technical field of mining accessories processing, in particular to a split forging die. Background Art

[0002] Mining accessories play a vital role in the mining industry. Some mining accessories, such as mining machinery and transportation equipment, can greatly improve the production efficiency of mines. The performance and usage of these equipment directly affect the production capacity and economic benefits of mines. In order to improve the service life of some mining accessories (racks, E-shaped bolts and scrapers, etc.), forging processing will be carried out. The forging process is inseparable from the use of forging dies. Existing forging dies are generally composed of upper dies and lower dies. During the processing, the heated blank is placed inside the lower die, and then the upper die is moved down and closed with the lower die for forging. The structure is simple and the processing cost is low, but the upper die and the lower die are generally an integrated structure. When the die is partially damaged, it needs to be replaced as a whole, which increases the cost of using the die. At the same time, the size of the blank before forging is generally smaller than the die cavity, which requires the processing personnel to place it in the center, but there is a lack of positioning components inside, and the poor centering will affect the subsequent processing quality.
