点火枪枪管 QG-91

1. Non-conformity inspection method of rounded corners: the radius of rounded corners measured by visual and inspection tools is not uniform or clear enough.The outer cover is not allowed to exist, some assembly surface and lap surface of the inner cover not only affect the appearance of precision stamping parts, but also seriously affect welding and assembly.

Inspection method: visual inspection.The existence of pit bag seriously affects the appearance quality of covering parts after painting, which is a defect that the customer cannot tolerate.Large area of pit bag will also affect the strength of precision stamping parts, fatigue, unable to repair.

Inspection method for material defects: visual standard: material strength does not meet the requirements, traces left by rolled steel plate, overlap, orange peel, striation, loose galvanized surface, peeling galvanized layer.

4 deformation (bump, dent, wave) inspection method: visual, polishing, touching, oiled A type of defects: users can not receive the defects, precision stamping parts manufacturers without training users can also notice, A type of dent pond found must be immediately on the precision stamping parts frozen.Class B defect: it is a kind of unpleasant defect, it is a kind of C defect that can be felt and seen and determined on the surface of the precision stamping parts: it is a defect that needs to be corrected, most of which are in ambiguous situation, and can only be seen after the polishing of the whetstone.

5. Inspection methods of hair drawing, indentation and scratch: it is not allowed to have hair drawing, scratch and indentation on the outer surface covered visually;The inner surface of the outer cover of the spray hood of the lighter is not allowed to have scratches or indentation that affect the quality of the outer surface.The surface of the inner cover is not allowed to have serious scratch or indentation which may cause the parts to tear.

6 wrinkling inspection method: visible outer cover is not allowed to have any wrinkles easily detected by customers, while the inner cover is not allowed to have serious wrinkling which may lead to material stacking.

Burr inspection method: the length of the visual burr should be less than 10% of the thickness of the plate.Any burr that affects the degree of bonding is not acceptable.Any burr that is likely to cause personal injury is unacceptable.Any burr that affects part positioning and assembly is not acceptable.

Stacking inspection method: visible outer covering parts are not allowed to have stacking defects, different degrees of stacking defects of inner covering parts will lead to customer complaints, functional precision stamping parts also affect the assembly of parts and body strength.

Inspection method of corrosion: visual inspection and dissections.Rust is the result of long-term storage or improper storage of precision stamping parts, which has a vital impact on the function, strength and fatigue resistance of stamping parts.

Grinding defects, grinding mark inspection method: visual, grinding A type of defects: polished through, visible on the surface, all customers are immediately visible.Class B defects: visible, palpable, and proven after polishing in disputed areas.Class C defects: visible after grinding with a whetstone.

Inspection method of cracks: visual inspection.Any fragmentation of the outer cladding is not acceptable.Minor cracks in the inner cover parts are allowed to be repaired by welding, but the repaired parts are not easy to be detected by customers and must meet the repair standard of precision stamping parts.

Neck tightening examination method: visual, section.Necking is a potentially dangerous breaking point in the forming process of precision stamping parts, which has a vital influence on the function, strength and fatigue resistance of precision stamping parts.According to the degree of necking to determine whether the precision stamping parts qualified, repair, scrap, etc.The shrinking neck of the outer cover affects the appearance of the vehicle, which is unacceptable to the customer.

Inspection method of pitting: visual, polishing, touching and oiled type A defects: pitting points are concentrated, and pitting points are distributed when the supply of lighter cover exceeds 2/3 of the whole area.Class B defects: pitting can be seen and touched.Class C defect: single scattered pitted points can be seen after grinding, and the distance between pitted points is required to be 300mm or larger in area 1.
