Description

Press forging die

The present invention relates to a press forging die, and more particularly to a one-time forming press die.

When a material is subjected to an external force to change the shape or size of the material itself, the form of the change is called deformation. The deformation is generally divided into elastic deformation and plastic deformation. In short, when the force applied to the material is removed, if the original shape and size are completely restored, the deformation of the material is said to be elastic deformation; otherwise, if the external force is removed If the material cannot be restored to its original shape, the deformation of the material is said to be plastic deformation.

Because metal materials have advantages such as high strength, high durability, and high stability compared with other materials, and because of the high yield of metal and good processability, metal materials are suitable for mass production. Therefore, operators often use various metals as materials to produce machinery and devices to promote the progress of human life.

Plastic processing uses a tool or a mold to apply an external force to the material to plastically deform the material to become the desired shape, size, performance, and processing of the product of the crystal structure. Compared with other materials, the same plastic processing method, metal plastic processing has the advantages of high material utilization, good dimensional accuracy and high production efficiency. In addition, metal plastic processing can not only deform the material, but if a large external force is applied to the metal material, the metal material changes its crystal structure due to extreme pressure, and the strength of the metal material can be The durability is greatly improved.

Among the various methods of metal plastic working, the most common methods are forging and stamping. The forging system utilizes a forging press and a die to generate and transmit a pressure of impact or extrusion to plastically deform the metal material to obtain a desired geometry, shape, and mechanical property of the article. In addition, the plastic deformation of the material during the forging process can improve the grain structure of the metal material itself, make the material finer and homogenized, and obtain good mechanical properties such as fatigue resistance, toughness and impact resistance. Briefly, the metal material has a work hardening property, that is, when a load is applied to the metal to cause plastic deformation, the internal structure of the material changes to increase the strength of the metal.

The press working system utilizes an external force generated by a press machine to generate a necessary stress by the action of the mold to form a plastic deformation, thereby forming a plastic working method for manufacturing various products by processes such as punching, bending, and drawing.

In the prior art, if the two metal plastic working methods are combined, that is, the forging technique is combined with the stamping die to form the press forging process, such a press forging method enables the material to be made larger by forging in addition to the press forming. Range of deformation and large thickness changes. It can be seen that in the press forging process, the workpiece can be changed in thickness, the shape can be more complicated, the size can be smaller, and the material used can be lighter. These advantages are in line with the complexity, lightness and fineness of the current product parts. Claim.

However, in the press-forging process of the prior art, the material often requires multiple steps of stamping and forging to complete the final product.

The invention provides a press forging die for processing a material, comprising an upper die and a lower die. The upper mold includes an upper body, a first pressing member, and a pressure-removing material plate. The first pressing member is used for pressurizing the material, and the depressurizing material plate is located at a side of the first pressing member, and the depressing material plate is used for pressing and releasing the material member. The lower die is opposite to the upper die, and the lower die includes a lower body, a second pressing member, and a carrier plate. The second pressing member is opposite to the first pressing member, and the second pressing member is configured to receive the material and shape the material, and the supporting plate is located at a side of the second pressing member, and the supporting plate is opposite to the pressing device. The material board and the material board are used for receiving the material. When the first pressing member and the pressure-removing material plate pressurize the second pressing member and the supporting member, respectively, a first gap is formed between the first pressing member and the second pressing member, and the pressure is released. A second gap is formed between the material plate and the carrier plate, and the first gap communicates with the second gap.

Therefore, compared with the prior art, the press forging die of the embodiment disclosed in the present invention forms a shape having a different thickness by the action of the upper die and the lower die, and at the same time, the disclosed embodiment of the present invention It can be formed by only one press forging process.
