Embodiment Construction
[0032] Material inspection: check the surface quality of the material, oil stains, burrs are not allowed, bumps and scratches are not allowed to exceed 0.1 times the thickness of the plate, and the maximum does not exceed 0.5mm; according to the production order, compare the length and width dimensions of the material with reference to the drawings , Socket form, thickness dimension, flatness, etc. shall be inspected.
[0033] Grinding and cleaning: Lift the parts to the grinding stand or platform, and use dry cotton cloth to remove the dust on the surface of the profile and parts. Use a straight handle grinder to grind the weld area, the grinding area is 15-25mm, and the grinding is required until the metallic luster is exposed.
[0034] refer to figure 1 , optimize the aluminum structure at the end of the underframe, and divide the overall structure of the end of the underframe into end beam traction beam synthesis 1, end beam front plate 2, end beam bottom plate 3, and und...
