The press forming is a processing and forming method for obtaining a workpiece (stamping part) with a required shape and size by applying an external force to a plate, a strip, a pipe, a section and the like by a press and a die to cause plastic deformation or separation.
Wherein, the sand blasting is a process of cleaning and coarsening the surface of a matrix by using the impact action of high-speed sand flow. Compressed air is used as power to form a high-speed spray beam to spray materials (copper ore sand, quartz sand, carborundum, iron sand, Hainan sand and glass beads) to the surface of a workpiece to be treated at a high speed, so that the appearance or the shape of the outer surface of the workpiece is changed, and the surface of the workpiece obtains certain cleanliness and different roughness due to the impact and cutting action of an abrasive on the surface of the workpiece, so that the mechanical property of the surface of the workpiece is improved, the fatigue resistance of the workpiece is improved, the adhesive force between the workpiece and a coating is increased, the durability of a coating is prolonged, and the leveling and decoration of a coating are facilitated. In this example, the inner surface of the base pot was sandblasted using glass beads.
Among them, hard oxidation is entirely called hard anodizing. The hard anodic oxide film generally requires a thickness of 25-150um, most of the hard anodic oxide films have a thickness of 50-80um, and the film thickness is less than 25um, and is used for parts of use occasions such as tooth bonds and spirals, the thickness of the wear-resistant or insulating anodic oxide film is about 50um, and under some special process conditions, the hard anodic oxide film with a thickness of more than 125um is required to be produced, but the thicker the anodic oxide film is, the lower the microhardness of the outer layer can be, and the roughness of the film surface is increased. The bath solution for hard anodizing is usually sulfuric acid solution and sulfuric acid with organic acid, such as oxalic acid, sulfamic acid, etc. In addition, the hard anodizing treatment can be achieved by lowering the anodizing temperature or lowering the sulfuric acid concentration. Special measures to increase anodization may also be considered for wrought aluminum alloys with copper contents greater than 5% or silicon contents greater than 8%, or high silicon die cast aluminum alloys.
The brazing method is a welding method in which brazing filler metal lower than the melting point of a weldment and the weldment are heated to the melting temperature of the brazing filler metal at the same time, and then the liquid brazing filler metal is used for filling gaps of solid workpieces to connect the metals. During brazing, an oxide film and oil stains on a contact surface of a base material are removed firstly, so that a capillary tube can play a role after the brazing filler metal is melted, and the wettability and the capillary fluidity of the brazing filler metal are improved.
According to the embodiment of the invention, the titanium-aluminum composite material pot production method is provided, the titanium-aluminum composite base material is punched and formed and is subjected to hard oxidation treatment, so that an oxide layer is formed on the surface of the base material, the hardness and the corrosion resistance of the surface of the base material cookware are enhanced, the aluminum sheet layer and the magnetic sheet layer are brazed at the bottom of the base material cookware, so that the bottom of the cookware is thickened, the bottom is not easy to deform during use, and the bottom is pasted with a protective film before the hard oxidation step, so that the contact position of the bottom of the base material cooker and the aluminum sheet layer and the magnetic conductive sheet layer is not oxidized, make aluminium lamella and magnetic conduction lamella direct and titanium aluminium combined material contact, the welding is more firm, adopts the glass pearl to carry out sand blasting to the internal surface of substrate pan at last, increases surface hardness and color and luster luminance, makes the pan have better performance for the pan is more pleasing to the eye durable.
