Technical Field
[0001] The utility model relates to the technical field of forging steel, in particular to a punching punch for forging steel billets. Background Art
[0002] A forging steel punch refers to a punch used in the forging process. It is mainly used for upsetting forging and is divided into two categories: primary upsetting punches and forming punches. A punch is a metal part installed on a stamping die, which is used to directly contact the material to deform the material or cut the material. In the forging process, the role of the punch is crucial. It can help achieve the precise forming of the material, thereby producing forgings that meet the requirements. Forging is a metal forming process in which metal materials are plastically deformed by applying pressure to obtain workpieces with the required shape and size. In this process, as part of the die, the punch directly contacts the material and realizes the forming of the material through its shape and movement mode. Different types of punches, such as primary upsetting punches and forming punches, are used in different processing stages to achieve the gradual forming of the material. In addition, forging technology also includes various specific forging methods, such as closed-die forging and split-flow forging. These methods reduce the forging pressure and improve production efficiency through specific die design and material flow control. Closed-die forging is to put the blank into the cavity formed by the upper and lower dies and compress and deform the material through the upper and lower punches, while split-flow forging designs spaces for the material to flow in the main direction and the reverse direction of the material flow to reduce the forging pressure. The application of these technologies makes the forging steel punch play an important role in the metal processing industry. With the development of society, when punching is required during the forging of steel, a punching punch is used.
[0003] When workers need to punch steel, they place the punch on the heated steel and start the machine so that the machine pushes the punch to process the steel. However, during the use of the punch, it will frequently contact the heated steel, and the heat on the surface of the steel will be transferred to the surface of the punch, resulting in a decrease in the hardness of the punch due to the influence of temperature, and then leading to deformation problems of the punch during the processing. Content of the Utility Model

A water storage groove is opened on the surface of the placement bottle, and a water inlet is fixedly connected to the surface of the placement bottle. A threaded block is threadedly connected to the surface of the water inlet. A pushing mechanism is arranged on the surface of the placement opening. The pushing mechanism includes a storage groove, which is opened on the surface of the placement opening and is located at the center of the placement opening. The storage groove can cooperate with the placement opening to achieve the purpose of storing the pushing spring.
[0006] Preferably, a push plate is placed at the bottom of the placement bottle, and a pushing spring is fixedly connected between the push plate and the storage groove.

[0011] 1. In the present utility model, by providing a heat absorption device, when the punch is in use, the impact of heat on the punch is reduced. The steel billet is heated to 1000 - 1200 degrees and forged into a good steel billet using a forging hammer or a press machine. Then, a punch is used to punch holes. For a 200 - millimeter - high steel billet, the punch punches to a depth of 170 millimeters. If it is a round billet, it is rolled round. When the forging and rolling round punch is used, it will fall off. It is also possible to punch down with one punch and let it fall downward. Place it on a drain pan below, and then place a second punch on top and punch downward. The first punch will fall off, and the hole will be formed after the second punch passes through.
