Feature application

Among the global steel products, 50-60% are made of plates, most of which are finished products by pressing. Automobile body, radiator plate, drum of steam pot, shell of container, electric motor, iron core silicon steel plate of electric appliance, etc. There are also a large number of stamping parts in instruments, household appliances, office machines, safekeeping utensils and other products. Stamping is an efficient production measure. It adopts compound die and multi-stage progressive die. It can complete multi-channel stamping operation on a press and complete the automatic generation of materials. It has the advantages of fast generation, long rest time, low production cost, and can produce hundreds of pieces per minute. It is loved by many processing plants.

There are thin, uniform, light and strong characteristics in stamping parts, castings and forgings. The workpiece with reinforcing rib, rib, curl or flanging, which is difficult to be made by stamping, can be made to improve its rigidity. Because of rejecting the rough die, the precision of the workpiece can reach micron level, and the precision is high, the specification is consistent, and it can punch out the hole, the boss and so on. In practical production, it is often used to test the stamping performance of materials, such as drawing performance test and bulging performance test, which are similar to the stamping process, in order to ensure the quality of finished products and high qualified rate.

In addition to the heavy plate forming by water press, the stamping equipment usually adopts the stagnant press. Focusing on the modern high-speed multi position stagnant press, the equipment is equipped with uncoiler, finished product collection, delivery and other stagnant equipment as well as mold library and quick mold change placement, and the computer French tube bundle is used to form a passive stamping production line with high production rate. Under the condition of producing tens or hundreds of stamping parts per minute, the process of stamping and output parts can be completed in a short time, and personal, equipment and quality accidents often occur. Therefore, safety production in stamping is a very important problem.
