With the continuous development of laser processing technology, the application level of laser processing equipment continues to expand, and the price of laser processing equipment continues to increase. “In the past two years, the HKPC has laser-assisted incremental molding technology, which has improved the ability of metal stamping to produce high-strength lightweight components. Create local metal powder. Laser processing is closely related to 3D metal printing.
The HKPC introduced the first hybrid 3D metal printing equipment in Hong Kong two years ago, and combined laser sintering and milling technology to produce high-precision molds and key components. Laser sintering is the key technology of three-dimensional metal printing. Laser irradiation is used to sinter and process the metal powder on the metal base plate and “print” layer by layer. Although the price of existing 3D metal printers has gradually dropped, the price of powder is imported from abroad, which is expensive and pushes up the overall cost.
Spinning products processing
Stainless steel spinning: The slab and the core mold rotate together, and the rollers feed and apply pressure to make the slab close to the core mold and locally deform at points. Spinning can be used to manufacture various axisymmetric rotating parts, such as loudspeakers, bombs, high-pressure vessel heads, and gongs; it can also be used for gas cylinder closing, tube blank forming, etc. The characteristics of the processing process of stainless steel spinning products are: a very small deformation force can be used to form large workpieces; the equipment used is relatively simple, small and medium-sized thin plate parts can be spun on an ordinary lathe; the mold is relatively simple, and only one piece is needed Mandrel, material requirements are very low. Spinning is suitable for small batch production, because it can only process rotating parts, which has large limitations and low productivity.
Stainless steel spinning manufacturers can use special machinery for spinning, using profiling spinning and digital control spinning. The process of making the plate thickness thinner while spinning forming is called thinning spinning, also known as strong spinning. It is mostly used for processing conical parts, thin-walled tubular parts, etc., and can also be used for spinning large-diameter deep The tube is then cut into a flat plate.
