Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a hot pressing forming process for manufacturing metal products. Background Art

[0002] In the field of metal product manufacturing, hot press forming is a commonly used processing method. Traditional hot press forming processes usually have some problems, such as insufficient preparation of raw materials resulting in unstable product quality, unreasonable mold design affecting molding accuracy, inaccurate temperature and pressure control during hot pressing leading to product defects, etc. In addition, improper operation during cooling and demolding can easily cause deformation or cracking of the product. Imperfections in the post-processing process may also reduce the appearance quality and performance of the product. With the continuous advancement of science and technology and the growing market demand for high-quality metal products, the limitations of traditional hot press forming processes have gradually become apparent, and an improved version of the hot press forming process is urgently needed to improve production efficiency and product quality. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the present invention provides a hot press forming process for manufacturing metal products, which has the advantages of improving production efficiency and product quality, and solves the limitations of traditional hot press forming processes.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a hot press forming process for manufacturing metal products, comprising the following processes, S1: raw material preparation, S2: mold design and production, S3: preheating treatment, S4: hot press forming, S5: cooling and demolding, S6: post-processing and S7: packaging and storage.

[0007] Preferably, the S1: raw material preparation, selects high-quality metal raw materials, cuts and cleans them according to product requirements, removes oil stains, rust impurities on the surface, ensures that the surface of the metal material is clean and tidy, so as to improve the quality of hot pressing.

[0008] Preferably, the S2: mold design and production, according to the shape and size of the required metal product, design and produce a high-precision hot pressing molding mold, the mold material should have good heat resistance, wear resistance and strength to ensure that it will not be deformed or damaged during the hot pressing process. At the same time, the mold is finely processed and polished to ensure that the mold surface is smooth, so as to facilitate the smooth flow and forming of the metal material in the mold.

[0009] Preferably, the S3: preheating treatment preheats the prepared metal material and the mold respectively. The preheating of the metal material improves its plasticity and fluidity and reduces the deformation resistance during the hot pressing process. The preheating of the mold prevents the metal material from generating crack defects due to a sudden drop in temperature when it contacts the mold. The preheating temperature is adjusted according to the type and thickness of the metal material, generally within a certain proportional range of the melting point of the material.

[0010] Preferably, S4: hot pressing molding, the preheated metal material is quickly placed into the preheated mold, and then appropriate pressure and temperature are applied for hot pressing molding. The pressure should be adjusted according to the properties of the metal material and the product requirements to ensure that the metal material can fully fill the mold cavity and obtain the required shape and size. Temperature control is also very critical. Too high a temperature may cause the metal material to soften excessively or even melt, while too low a temperature will make the metal material insufficiently plastic and difficult to mold. During the hot pressing process, a segmented pressurization and heating method is adopted to gradually increase the pressure and temperature to ensure the stability and uniformity of the molding process.

[0011] Preferably, in S5: cooling and demolding, after the hot pressing forming is completed, the mold and the metal product are cooled together. The cooling method is natural cooling, air cooling or water cooling, which is selected according to the properties of the metal material and the product requirements. The cooling speed should not be too fast to avoid excessive internal stress that may cause product deformation or cracking. When the mold and the metal product are cooled to a certain temperature, the demolding operation is performed to take the formed metal product out of the mold.

[0012] Preferably, the S6: post-processing is to post-process the metal product after demolding, including removing the flash and burrs, and performing surface treatment (such as polishing and spraying) to improve the appearance quality and corrosion resistance of the product. At the same time, the product is quality tested, including dimensional accuracy, surface quality, and mechanical properties to ensure that the product meets the design requirements and relevant standards.

[0013] Preferably, in S7: packaging and storage, qualified metal products are packaged using appropriate packaging materials and methods to protect the products from damage during transportation and storage. At the same time, the products are stored in a dry, ventilated environment without corrosive gases to prevent the products from moisture, rust or other damage.

[0015] Compared with the prior art, the present invention provides a hot pressing forming process for manufacturing metal products, which has the following beneficial effects:

[0016] 1. The hot pressing process used in the manufacture of metal products can improve product quality. Through strict raw material preparation, impurities removal and dimensional accuracy, the foundation for high-quality products is laid.

The temperature, pressure and time are accurately controlled to fully fill the mold cavity with metal materials, reduce internal defects of the products, and improve the mechanical properties of the products.
