  • Control de precisión: la máquina de inclinación de CNC puede lograr ± 0.1mm tolerance , sin soldadura en la superficie. Welding is easily affected by operation and needs to be polished in Procesamiento posterior.
  • Eficiencia: la lámina de metal es adecuada para la producción en masa estandarizada, mientras que la soldadura es más adecuada para reparar o refuerzo parcial de piezas de chapa.

limitaciones:

La soldadura puede conectar materiales diferentes (como metal y plástico), mientras que la chapa se limita a láminas de metal similar.

escenarios aplicables:

  • Selección de placa: producción estandarizada de piezas de placa (como soportes eléctricos, estantes, etc.).
  • Elija soldadura: reparar defectos, conectar materiales diferentes o reforzar temporalmente (como el acero de construcción).

en la hoja de metal Fabricación , la selección de material razonable es la clave para garantizar el equilibrio entre el rendimiento del producto y el costo. gráfico de medidor de chapa y parámetros relacionados para proporcionarle una guía de selección sistemática:

1. Aclarar los requisitos de la aplicación

  • Requisitos funcionales: de acuerdo con la capacidad de carga, resistencia a la corrosión y conductividad eléctrica del material, elija diferentes materiales.
  • Limitaciones del proceso: para los materiales complejos de curva metálica, se debe dar prioridad a los materiales con buena ductilidad (por ejemplo, aluminio lámina de metal), mientras que para las estructuras soldadas, los puntos de fusión de materiales (por ejemplo, acero sin soporte con requisitos de calor más altos) se deben considerar.

acero inoxidable antioxidante, resistente al calor, antibacteriano. Equipo químico y médico (necesidad de equilibrar los costos y los requisitos de higiene).

4. Adaptación de parámetros de proceso

  • Proceso de curva de chapa: las placas delgadas (por ejemplo, 24GA) requieren moldes con ranuras V más pequeñas para evitar grietas, mientras que las placas gruesas (por ejemplo, 16GA) requieren presión adicional.
  • Compatibilidad de soldadura: las placas de aluminio requieren protección de gas inerte para la soldadura, y la soldadura por arco de argón se recomienda para acero inoxidable (los parámetros deben ajustarse al espesor del material).
  • Surface treatment: Galvanized sheet metal can be sprayed directly, while aluminum sheet metal require anodic oxidation pretreatment (process cost differences need to be taken into account in selection).

Application of Sheet Metal Manufacturing in the Automotive Industry

What are the sterilization requirements for surgical robot sheet metal components?

1.Adaptability requirements for sterilization methods

Material compatibility screening

  • Stainless steel components (e.g. 304/316L): Suitable for high temperature, high pressure steam sterilization. JS provides a high temperature resistant scaffold for surgical robots with accuracy of ±0.005mm after more than 300 sterilization cycles.
  • Aluminum alloy components: Ethylene oxide is recommended for sterilization to avoid high-temperature deformation. After ETO sterilization, the torque performance of a JS joint module remains unchanged.
  • Plastics/composites: Radiation sterilization is preferred, and the JS sensor housing is made of PEEK material with a a tensile strength retention rate greater than 95% after irradiation.

Surface treatment strengthening: Sheet metal parts need polishing Ra<0.8μm and passivation (e.g. anodic oxidation). JS cases shows that the process can reduce sterilization residue by 80%.

2.Verification and compliance management

Biocompatibility verification

These ingredients are subject to ISO 10993 series tests (cytotoxicity, allergies, etc.), and JS's needle holder components are sourced from a manufacturer and approved by FDA 510(k).

Sterilization Verification Report

Data on sterilization process parameters (e.g. ETO concentration, irradiation dose) and material performance were provided to shorten the sterilization cycle by 20% without affecting the assurance level of sterilization (SAL 10^-6).

3.Integration of production processes

JS has very strict control over the workshop and the dust-free workshop complies with ISO 7 standards. After sheet metal processing, use ion air, reduce particle residue, combined with automatic packaging and sealing, reduce the risk of secondary contamination.

4.Cost and productivity

  • Modular design: JS splits the surgical arm into three separate sterilization units, saving 40% of time compared to traditional holistic disinfection, while meeting the requirement for an emergency delivery within a week.
  • Material substitution solution: For high-value components, titanium alloy are recommended in place of stainless steel. While costs increases by 15%, sterilisation life tripled and the comprehensive TCO decreased by 22%.

5.JS typical cases

In the total hip replacement surgery robot project of an international medical giant, JS provided acetabular polishing components using:

  • Material: Ti6Al4V titanium alloy sheet (5mm).
  • Sterilization plan: Plasma sterilization (to prevent gamma rays from titanium discoloration).
  • Performance: After 10 sterilization cycles, the surface roughness was stable at Ra=0.4μm with precision error of less than 0.01mm, helping clients shorten the clinical trial cycle by 3 months.

Sterilization requirements for surgical robot sheet metal components

How to replace stainless steel with galvanized sheet metal to achieve the same strength?

1.Choose high-strength alternatives

  • High-strength galvanized sheet: Choose high-strength low-alloy steel as the base, its tensile strength can be over 600MPa, close to ordinary stainless steel (such as 304 stainless steel, a tensile strength is about 515MPa).
  • Double layer galvanizing process: Aluminum zinc plating is adopted on the surface of cold rolled steel plates to improve corrosion resistance while maintaining the high strength characteristics of substitute material.

2.Sheet metal fabrication technology

  • Cold rolling reinforcement: The yield strength of galvanized sheet is increased by cold rolling (When the cold rolling deformation exceeds 30%, the strength can be increased by 20%-30%).
  • Annealing control: Use incomplete annealing (such as recrystallization annealing) to balance strength and ductility and avoid excessive softening.
  • Surface treatment strengthening: Passivation or phosphorylation of the galvanized layer to reduce the risk of microcracks during sheet metal bending.

3.Structural design

  • Ribs/flanges: Design of reinforcement or flange structures in key stress areas of sheet metal parts to enhance bearing capacity through geometric shapes (e.g. car chassis parts).
  • Bending angle optimization: Using stair bending (Z bend) instead of right angle bending, scattered stress concentration, improve overall stiffness.
  • Curling process: The edges of thin sheets (e.g. 5mm thick galvanized sheet metal with a curl radius ≤1t) are curled to prevent sheet metal bending and enhance bending strength.

4.Welding and connection process

  • Resistance welding in place of riveting: On the basis of good galvanized sheet conductivity, spot welding or seam welding can reach more than 80% of the strength of the substrate (welding current needs to be controlled to avoid evaporation of the zinc layer).
  • Laser welding: High energy laser welding can reduce the heat effect area, avoid strength attenuation caused by zinc coating melting, and reach joint strength close to stainless steel.

5.Verification and testing

  • Tensile test: The yield strength of galvanized sheet ≥355MPa (Equivalent to one-third of the strength of 304 stainless steel).
  • Cyclic load test: Simulation of actual working conditions (such as vibration, impact, etc.) to verify that the fatigue life of galvanized sheet metal meets the standards.
  • Sheet metal bending rebound compensation: Through die prebending or angle correction, to ensure that the dimensions of the bending accuracy and stainless steel parts.

Key preventive measures

  • Avoid excessive bending: Galvanized sheet metal are less malleable than stainless steel and should have a bending radius ≥1.5 times thickness (stainless steel generally ≥1 times).
  • corrosion reinforcement: In humid environments, epoxy resin is required to be partially sprayed or coated with an increased thickness (e.g., Dacromet treatment).
