1. Strictly abide by scientific and effective processing technologyClear production outline: determine the production type, analyze the parts drawing and product assembly drawing, and formulate a scientific and reasonable production process.Skill route planning: select the blank and formulate the skill route to ensure that the processing allowance of each process is reasonable, and calculate the process scale and public service needs.Equipment and tool preparation: determine the equipment, tools, fixtures, gauges and some auxiliary tools required for each process to ensure smooth production.Skill requirements and inspection methods: determine the cutting amount and working time quota, as well as the skill requirements and inspection methods of each major process to ensure that the processing quality is controllable.2. Do a good job of mechanical operation during the processing processWelding operation: Welding in stainless steel sheet metal processing usually includes hydrogen arc welding, spot welding, manual arc welding and carbon oxide shielded welding. When spot welding, the welding position should be considered to ensure the welding quality.Riveting operation: For the riveting of the workpiece, the height of the stud and the pressure of the press should be considered to ensure that the stud is flush with the surface of the workpiece to avoid scraping the workpiece.Appearance inspection: After the processing is completed, the appearance inspection is carried out, including the size and other aspects. If there is a problem, it should be repaired or scrapped directly to ensure the processing quality.3. Eliminate factors that affect processing qualityPhysical and mechanical properties: mainly the changes in the metallographic arrangement of the surface material and the residual stress on the surface. The stronger the plasticity of the workpiece material, the more obvious the cold hardening phenomenon. Therefore, it is necessary to reasonably select the cutting fluid to reduce the friction coefficient and cutting temperature, thereby reducing tool wear.Wear resistance and corrosion resistance: The better the wear resistance and corrosion resistance of stainless steel sheet metal processing products, the more it can prevent deformation, corrosion and other scenes, thereby preventing severe wear. Therefore, during the processing process, it is necessary to pay attention to protecting the surface of the material to avoid scratches or contamination.4. Correct use of precision processing technologyProcessing equipment accuracy: Ensure that the processing accuracy of the processing equipment meets the requirements, such as the accuracy of the lathe.Operator technical level: The operator needs to have a certain technical level, be able to operate the equipment skillfully and deal with problems that arise during the processing.Raw material requirements: For precision processing, the hardness and other properties of the raw materials need to meet the requirements to avoid damaging the equipment or affecting the processing quality during the processing.5. Pay attention to processing details and subsequent processingBending processing: When bending, the tool and knife groove used for bending should be determined according to the size and material thickness on the drawing. At the same time, it is necessary to prevent the product from colliding with the tool and causing deformation.Assembly and surface treatment: Before assembly, it is necessary to tear off the protective sticker used in spraying and ensure that the threaded holes of the parts are not sprinkled with paint or powder. Surface treatment generally includes phosphating film, electroplating colorful zinc, chromate, baking paint, oxidation, etc. The specific choice depends on customer requirements and material type.Post-welding treatment: After welding, the surface needs to be ground or cleaned to prevent local corrosion or strength loss.In summary, in order to obtain better stainless steel sheet metal processing quality, it is necessary to start from processing technology, mechanical operation, elimination of influencing factors, precision processing technology, processing details and subsequent processing, and comprehensively control the processing process.
In recent years, sheet metal processing has become more common, and good sheet metal processing technology requires good management, coordination and regulations of the company. Stainless steel sheet metal processing is a type of processing that is particularly present in the sheet metal industry. The products are also relatively wide. There are only a few steps in stainless steel sheet metal processing. If you want to have better stainless steel sheet metal processing quality, you must make changes in the sheet metal processing process.In the process of stainless steel sheet metal processing, operators play an important role and should be based on reasonable and appropriate processing planning.In the entire stainless steel sheet metal processing process, according to the normal procedure, there are only laser processing, CNC punching, shearing processing, bending processing and other processes. Therefore, stainless steel sheet metal processing must pay attention to the corresponding most suitable process at each step, including the technical selection of equipment. It is also necessary to keep up with the changes in drawings. For example, in the process of stainless steel sheet metal bending, it is necessary to choose suitable tools, molds, bending pressure, etc. In the welding process, the welding parts are required to be done. To ensure the accuracy of welding.DongGuan Win-Leading Hardware Technology Co., Ltd. has developed over the years and specializes in hardware products such as hardware molds, stamping products, sheet metal bending, laser cutting, CNC processing, etc. with excellent manufacturing level and service attitude. It is named for its influence in the world manufacturing industry and its product supply capacity that is all over the world. Welcome new and old customers to call for inquiries.
