The forging press process is an important method for processing metal materials. Forging is a forming process that uses a hammer or press to heat a metal blank to a certain temperature to form it into a certain shape. The following takes a 2,000-ton forging press as an example to introduce its process flow. 1. Billet heating: First, put the metal billet into a heating furnace for heating. The general heating temperature is about 1100℃-1250℃, so that the billet can reach an easily deformed state. 2. Forming: Place the preheated blank on the forging press and start the forging press for forming. During molding, the molding speed and molding pressure should be gradually increased to avoid poor build quality. When molding, you need to operate patiently and carefully to avoid wall, cracking, breakage, etc. 3. Cooling: After molding is completed, use water to cool it immediately to avoid overheating of the blank and affecting the quality of the finished product. The general cooling rate is 5-10 minutes, and the specific time can be adjusted according to the forming speed and billet size. 4.Processing: The cooled formed parts can be finished. Lathes, milling machines and other mechanical processing equipment are usually used to process the size, surface quality, etc. of the finished product to meet customer requirements. 5.The above are the basic steps of the forging press process. A specific case is given below: a forging factory named XX company needs to produce a batch of φ200mm×800mm shafts. This shaft is processed from SAE1045 steel. The specific production process is as follows: 1. Material preparation: Purchase SAE1045 steel and learn from the chemical composition analysis of the steel. Its main components are 0.45% carbon, 0.75% manganese, and 0.15% sulfur. First, cut thesteel to the required size. 2. Preheating: Heatthe cut steel to 1100℃-1250℃ through the heating furnace, then take it out and place it on the forging press. 3. Forming: The steel on the forging press is formed into a finished shaft with a size of φ200mm×1400mm. The finished shaft is required to have a high surface finish and a roundness of 0.03mm. 4. Cooling: After the finished shaft is forged and formed, it needs to be cooled in water for10 minutes so that the temperature of the finished shaft does not reach 250°C. 5. Processing: Finally, the dimensions are finely processed by lathes and milling machines to meet high-precision requirements.
