Description

Cold forging former device with direction change function

The present invention relates to a cold forging former device including a mold having a reversing function of the shape, and more particularly, to make the shape placed in the horizontal direction to be erected in the vertical direction quickly, shortening the work process and increasing productivity efficiency. The present invention relates to a cold forging former apparatus including a mold having a reversing function of a shape that can be made.

In general, forging refers to an operation of making a solid metal material into a certain shape by hammering or pressing a metallic material with a hammer, and forging at a temperature higher than the temperature at which recrystallization proceeds in the material. Forging at temperature is classified as warm forging, and forging at lower temperature is cold forging.

Among them, the cold forging process is used in various industrial machines because of the high productivity, especially in the automobile industry is an important process. Cold forging has high strength and high material strength due to the formation of a fibrous structure as the metal flow occurs along the outer shape of the forging, resulting in high durability and low material loss. In most cases, the production cost is lower than that of the product because it is less than 10% of the weight of the material. In addition, since it is mass-produced by press work, there is a feature that can produce a product with high productivity and high precision. Most of the process uses the equipment called Former.

However, when looking at the shape manufacturing process using the cold forging former device as described above, the prior art is a separate reprocessing process after the manual process and the overall process by the operator to manually change the orientation of the shape There was a problem that takes a long time for the work process in a way. In addition, there is a problem in productivity efficiency due to the slow processing speed.
