Sheet metal stamping parts of the relevant knowledge
Dongguan sheet metal stamping parts of the relevant knowledge of dongguan sheet metal stamping sheet metal processing is called sheet metal processing.
Concrete such as the use of plate making chimney, iron drum, and the size of the tank of the oil pot, ventilation pipe, elbow, head, day garden place, funnel, etc. , the main process is shear, bending, buckles, bending forming, welding, riveting, etc. , need to have some knowledge.
In the process of machining the thickness of the same parts.
Corresponding is casting parts, forging parts, machining parts, etc. , such as the outside of the car is iron clad sheet metal parts, some made of stainless steel kitchen utensils and sheet metal parts.
Based on both pieces of sheet metal structure, technological process can vary, but the total does not exceed the following points.
Flanging: also called pumping hole, hole, is in a small hole on the smoke into a larger hole, tapping again, mainly with the thickness of thin sheet metal pretty processing, increase the strength and the screw thread turns, avoid sliding tooth, commonly used in thickness is thin, its around the normal shallow flanging, the thickness of basic did not change, the thickness of thin 30 - are allowed
Can be obtained when the 40% larger than normal flanging height high - 40
50% 60% of the height, with crowded thin, will be the biggest flanging height, when the thickness is bigger, such as 2.
Above 5, such as thickness, can be directly tapping.
Press: is the use of mold forming processing working procedure, general punch processing of punching and cutting Angle, blanking, punching convex hull (
, tear, suction hole and forming processing, the processing needs to have the corresponding mold to finish operation, such as punching blanking die, convex BaoMo, tearing mode, pumping hole pattern, forming mould, etc. , operating mainly pay attention to the position, direction.
