The production process of automobile scale mainly includes the following key steps:
Scale structure design: The choice of scale structure of automobile scale has an important influence on its performance. Common structures include U-beam and steel welding. U-beam has the advantages of high rigidity, good strength, good processability and high corrosion resistance; while steel welding requires the addition of transverse ribs and bottom plates to improve local rigidity.
Manufacturing process:
Shearing and folding: Cut the steel plate into the required size and then bend it into U-shaped steel.
Positioning loading pre-arch: Ensure the dimensional consistency and pre-arch effect of the scale.
Welding: Use fully automatic submerged arc welding to ensure high welding quality and fast speed.
Calibration and debugging: Calibration and debugging are carried out under full weighing state to reduce on-site workload.
Sandblasting and rust removal and baking paint: Use environmentally friendly paint production line, including sandblasting, rust removal, painting and baking paint.
Key components and materials:
U-beam: Made of cold-rolled steel plate with a thickness of no less than 6mm to ensure strength and rigidity.
Panel material: Q235 steel plate is usually used.
Welding technology: CO2 protection welding is used to ensure the strength of the connector and avoid fatigue deformation.
Paint treatment: Zinc-rich primer and water-based anti-rust paint are used to ensure strong paint adhesion and non-fading.
Quality inspection and debugging: Overload test and continuous full weighing rolling test are carried out before leaving the factory to ensure that the scale body can remain stable under extreme load.
Through the above process flow and quality control measures, high-performance and high-precision truck scale products can be produced.
