Abstract
The invention relates to a processing method for a billiard used for a billiard lockset and a special mould thereof which continuously squeezes and processes to finish shaping the head and the tail parts of the billiard step by step in multi-working positions. A cylindrical metal wire is adopted as the stock to process the billiard; the stock is continuously transmitted and at the same time the two sides of the stock are grinded into a flat shape with a fixed distance ; the special mould is fed in to squeeze one end of the stock to form the steeple head part of the stock; then the stock is cut off the cylindrical metal wire and is fed into the shaping working position at the head part of the billiard, where the steeple head part of the stock is squeezed into an incomplete hemisphere; finally the stock is turned by 180 degrees and fed into the shaping working position at the tail part of the billiard with one end squeezing the tail part of the stock to form an annular chamfer angle and the other end squeezing the incomplete hemisphere of the stock into a complete hemisphere; the rest redundant stock of the squeezed part on the stock is squeezed to the two sides of the stock to enlarge the diameter of the stock to form a complete billiard. The processing method has the advantages of high precision and low cost for manufacturing the billiards.
