Embodiment 1

[0046] This example is used to illustrate the shaping method of the alloy of the present invention.

[0047] The 304 stainless steel plate (purchased from Xinshunxiang Stainless Steel Co., Ltd.) was made into two samples A1 and A2 of length 70mm×width 30mm×thickness 1.2mm. The flatness of sample A1 was 0.03mm, and the sample A2 was bent and deformed. Samples A1 and A2 as figure 2 shown.

[0048] Place sample A2 in such as figure 1 In the shaping device shown, the deformation of sample A2 is measured in the measurement area, and the maximum deformation of the measurement result is 1.51mm. Rotate sample A2 from the measurement area to the shaping processing area, and use the compressed air mixed shaping fluid with a pressure of 0.4Mpa containing B505 ceramic particles (purchased from Henglida Surface Treatment Materials Co., Ltd., with a particle size of 10-30 μm) to sample A2. Plastic processing, the mixing ratio of B505 ceramic particles and compressed air is 1×10 5 pcs / L...

Abstract

The invention discloses a shaping method for an alloy product. The method comprises the steps that liquid is sprayed to a position to be shaped of the alloy product, and the position to be shaped is deformed; and shaping particles are mixed in the liquid. According to the shaping method for the alloy product, the liquid is sprayed on the surface of an alloy, significant deformation, such as elongation, extending or bending, occurs in the sprayed position, and the corresponding deformation is produced mainly in the mode that through liquid spraying, residual stress of the alloy in the shaping process such as machining and casting is eliminated, so that local plasticity is shown, an alloy with large elasticity and poor plasticity can be shaped under the normal temperature condition, and predetermined deformation of the alloy occurs.

Description

technical field [0001] The invention relates to a method for shaping alloys, in particular to a method for shaping alloys with high elasticity and poor plasticity. Background technique [0002] Due to the nature of alloy products, it is difficult to ensure that no deformation occurs during the forming process, such as machining, extrusion, die-casting and other forming processes. Once deformation occurs, a certain shaping process is necessary to ensure that the product size meets the requirements. Conventional alloy shaping methods use specific shaping molds to continuously deform the product until it returns to the desired shape. For example, the shaping of aluminum-magnesium alloy products. Because aluminum-magnesium alloys have better plasticity, they can be restored to the desired shape through conventional alloy shaping methods, and shaping is more convenient. However, for metal materials with high hardness and low plasticity or high elasticity, it is difficult to meet...
