The various products that we often go to in large and small supermarkets are professionally produced by professional manufacturers, and then regular inspections will be placed on the shelves for people to buy. Stamping parts are no exception, but many people do not know what the inspection methods of stamping parts are. Next, we will introduce the inspection method of stamping parts.

 

Inspection steps:

 

— Touch the stamping parts

— Whetstone polishing

— Flexible gauze grinding

— Oil inspection stamping parts

— Visual inspection

— Gauge inspection

— Safe Production

 

Touch the stamping parts

 

Wipe the surface of the outer cover with clean gauze. The inspector is required to wear a touch glove to touch the stamped surface along the longitudinal direction of the stamping. This method of inspection depends on the inspector's experience. If necessary, oil stone can be used to polish and detect the suspected area, but this method is an effective and quick method.

 

Whetstone polishing

 

1. First wipe the surface of the outer cover with clean gauze, then polish with oil stone (20×20×100mm or larger), place with arc and hard to wear with relatively small oil stone.

2. The choice of particle size depends on the surface condition (eg roughness, galvanizing, etc.). Fine-grained oilstone is recommended. The direction of the stone grinding is basically in the longitudinal direction, and it fits well with the surface of the stamping part, and some special places can also complement the lateral grinding.

 

Flexible gauze grinding

 

Wipe the surface of the outer cover with clean gauze. The surface of the stamping part is sanded to the entire surface in a longitudinal direction by a flexible sand net, and any pitting and indentation can be easily found.

 

Oil inspection stamping parts

 

Wipe the surface of the outer cover with clean gauze. Then use a clean brush to evenly apply oil to the entire outer surface of the stamping in the same direction. The oil-coated stampings are placed under strong light and it is recommended that the stamped parts be placed in the body position. With this method, it is easy to find tiny pittings, ponds, and corrugations on the stampings.

 

Visual inspection

 

Visual inspection is mainly used to find the appearance abnormalities and macro defects of stamping parts.

 

Gauge inspection

 

The stamping part is placed in the inspection tool, and the stamping part is tested according to the operation requirements of the inspection tool manual.

 

Safe Production

 

In the case of producing dozens or hundreds of stamping parts per minute, the processes of feeding, stamping, discharging, discharging waste, etc. are completed in a short time, and personal, equipment and quality accidents often occur. Therefore, safe production in stamping is a very important issue.

 

Generally, in the stamping process, due to the stamping process, especially in the cold forging stamping process, the temperature will rise quickly. Lubrication must be added to the lubrication product. If the lubrication is not used, the stamping, welding-assembly, no oil on the surface the parts are easy to solder and assemble. Research and practice have shown that Amy's metal inert gas arc welding, tungsten gas shielded arc welding, and resistance welding has excellent results.

 

Many people are afraid to buy a product with quality problems when buying stamping parts. If there is a problem, it will be very troublesome to buy it back. Therefore, the method in the text will definitely help you to choose the test. If you want to buy stamping parts, you can also come to understand our company. I believe that our company can provide you with the most thoughtful service, the best quality products.
