Title: PROCESSING TECHNIQUE OF CRAFTED BEER BARREL
Abstract:
A processing technique of a crafted beer barrel, comprising: forming a barrel bottom and a barrel body by using a revolving-drilling composite technique; rolling an opening of the barrel body to form a first connecting portion on the barrel opening; necking down using a powerful spinning technique to form a lid with an opening at one end and processing a lid opening at the other end of the lid to form a second connecting portion at the lid opening; matching the first connecting portion of the barrel opening with the second connecting portion of the lid opening; and performing a rolling connecting process on the first connecting portion and the second connecting portion so that the barrel body and the barrel lid are connected into one body. The processing technique requires less procedures, reduces cost and saves raw materials. The crafted beer barrel processed with the technique is strong, and can be used circularly. According to the processing technique, a welding seam is avoided and the tensile strength of the container material is improved, thus satisfying the storage requirement of crafted beer.
