Compared with the castings, forgings, pressing with a thin, uniform, the characteristics of light and strong.
Stamping can make other methods are difficult to manufacture with rib stiffener, flanging, ups and downs, or artifacts, in order to improve its stiffness.
Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc.
Cold stamping generally no longer by machining, or only need a small amount of machining.
Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity.
Stamping is efficient production methods, the use of compound die, especially the multi-station progressive die, can be in a press (
Simplex or transfer)
On multichannel stamping process, realize the pick-up uncoiling, leveling, cutting to the forming and finishing of automatic production.
High production efficiency, good working conditions, low production cost, general can produce hundreds of pieces per minute.
Compared with other methods of mechanical processing and plastic processing, stamping processing both in technology and economy has many unique advantages.
Main show is as follows.
Stamping processing of high production efficiency, and easy to operate, easy to realize mechanization and automation.
This is because the stamping is depend on the die and stamping equipment to complete the processing, ordinary press stroke times per minute can reach dozens of times, high pressure to can reach more than hundreds of times or even one thousand times per minute, and every time stamping stroke can get one piece.
When stamping due to the size and shape of mold to ensure the stamping precision, and generally does not destroy the surface of the stamping parts quality, and the life of the mould are long, so the stamping quality is stable, good compatibility, has the characteristics of 'the same'.
Stamping machining size range is larger, more complex shape parts, such as small to watch the stopwatch, big to auto longeron, covering parts, etc. , and stamping material hardening effect of cold deformation, the strength and stiffness of stamping was high.
Press generally generated no chip broken material, material consumption is less, and do not need other heating equipment, it is a kind of material, machining method of energy saving, stamping parts of the cost is low.
