Abstract
The design mainly carried out a detailed interpretation on the automantic sheet feeding ,the processing of the feed punching machine and mold and including their principles. Cold punching processing is the most widely used in the processing technology, the degree of the automation do influence directly on the efficiency of the punching processing , processing rhythms and the overall level of automation. Now most feeding devices are directed at the material volumes which sent to the processing automatically, otherwise,few of the automatic sheet feeding devices .The main design for more than 5 mm automatic sheet feeding, use the cylinder-led push to promote the installation of automatic sheet feeding system and rely on two rollers devices automatic feed, and apply the use of sensors on detecting and control system of the machinery device . However, this design of the main mechanical parts, mainly reflects the characteristics of the simple feed system and the reliable and stable processing. Mold is used for making the chain board, considering on the processing precision, the formation requirements and efficiency issues of chain , here apply a flip-style compound form. Mold is made of two parts, upper mold and under mold .upper mold is fixed in the press slider, which is an active part, under mold is fixed in the punching table which is a stable part . This mold mechanism is compact and reliable.
Key word: Presswork Sheet Automatic Feeding Compound mold
