Description

  The present invention relates to a cold forging former apparatus including a mold having a function of turning a shape, and more particularly, to allow a horizontally placed shape to be quickly erected in a vertical direction. And a cold forging former apparatus including a mold having a shape-redirecting function capable of shortening the length and increasing the efficiency of productivity.

  In general, forging is a mechanical method in which a solid metal material is hit or pressed with a hammer or the like, and refers to an operation to make a certain shape, and a temperature above that at which recrystallization in the material takes place. It is divided into hot forging to forge, warm forging to forge at recrystallization temperature, and cold forging to forge at lower temperature.

  Among them, the cold forging process is used for various industrial machines because of its high productivity, and is an indispensable important process especially in the automobile industry. In cold forging, a metal structure (Metal Flow) is generated along the outer shape of a forged product, and a fibrous structure is formed to have high strength, so the durability is high and the loss of material is small. The production cost is lower than the product, since it is often less than 10% of the weight of the material. Moreover, since it is mass-produced by press work, it has the feature that mass production of a product with high productivity and accuracy is possible. For this reason, most of the processes use equipment called Former.

  However, considering the shape manufacturing process using the above-described cold forging former apparatus, the prior art has a method in which the operator manually changes the direction manually for changing the direction of the shape, or There is a problem that a long process time is required for the work process, such as a method of performing a separate re-process after the process is performed. In addition, since the processing speed of the process is slow, there is also a problem in productivity efficiency.
