Barrel Hoop OEM Deep Draw Metal Forming
The so-called barrel hoop is connected with the lid and barrel body with the iron ring to achieve the effect of sealing and fastening. Some need to be tightened only, while others need to be tested to withstand the pressure in the barrel without leaking. In this respect, there is no domestic data, the effect of the barrel hoop is relatively poor, and the principle is also to rely on their own manual to explore, there is no specific theory. The barrel hoop is made in Japan, which is characterized by simple appearance, light quality and good pressure test effect.

1)By forming the workpiece raw materials, after processing of raw materials in appearance, such as raw materials for phosphating, coating or other physical treatment, cause the forming material appearance form a layer of metal mould, can greatly reduce or eliminate artifacts strain, this method usually capital is higher, and the fruit of the demand for other equipment and increase the production process, Although this method is sometimes useful, it is rarely used in practice.
2)Between the workpiece and the mold, between the mold and the forming material with a layer of PVC film, sometimes also can deal with the workpiece strain question. On the production line through the organization can reach the continuous supply of film, and on the cycle of production of stamping equipment, each production of a piece of workpiece needs to add a film, affecting the production power, this method is usually high cost, but also produces a large number of waste, on the production of small batches of large workpiece selection of this method is desirable. In some forming load is very small occasions, sometimes through the increase of lubricating oil or add EP additive lubricating oil can deal with the problem of workpiece strain.
3)Mold by changing the mold convex, concave die material or die convex, concave die surface treatment may choose the appropriate mold material, so that the tensile material and convex, concave die so touch the nature of the change. Practice has proved that this is an economical and useful way to deal with the problem of strain, and is now widely used.
