During the use of the die casting machine, the punch is easy to be worn. Once the punch is worn, it will have a negative impact on the quality of the die casting. Most die castings processed with worn punches have flaring or returns, which may cause cost pressure to the enterprise virtually. How to select and use correctly can make the punch swing better. Here are some notes on the use of the Punch.
First of all, we need to have a general understanding of the types of cold chamber die-casting machine punches. The types of punches available on the market can be divided into gray iron punches, ductile iron punches, ceramic punches, 45 steel high-frequency punches, H13 die steel alloy punches, nano ceramic laser punches, and so on.
Bokasi ya likolo ya punch oyo eponami esengeli kozala HRC45 ± 2 degrés. Soki makasi ezali na nse mingi, punch ekolata sima ya ntango mokuse ya kosalela, oyo ekosala ete bomoi ya mosala ya punch. ezala mokuse soki makasi ezali likolo mingi, baril ya koleisa ekozala pete mpo na kolata, oyo ekokómisa bomoi ya koleisa{44}
The lubrication of the cold chamber die-casting machine punches can effectively extend their service life, so it is necessary to reasonably select lubricants at ordinary times. The commonly used lubricants can be divided into four categories. One is the lubricant without graphite, the other is the lubricant based on mineral oil and containing graphite, the other is the wax particle lubricant, and in addition, the water-soluble Lubrifiant oyo esalemi na synthèse.
Na tango ya bosaleli, esengeli kopesa likebi na bosaleli ya malamu ya punch. na nzela ya méthode ya bosaleli ya malamu, diplôme ya kolata ekoki pe kokitisa. Na tango moko, esengeli kopesa likebi na bopusi ya libunga ya bokeli, libunga ya botiami pe coefficient ya bopanzani ya molunge na punch.
