Received a consultation from Mr. Hu, regarding the continuous punching of 2.3mm acid washed plates with an I-shaped narrow edge punch width of 2.75. Currently, using DC53 will always break after punching for 4-5000 times. What kind of tool<\/strong> steel<\/strong> do you need?<\/p>\n\n\n\n

This is a narrow edge I-shaped punch with a relatively large amount of drift, and the punch width is close to the plate thickness, with a stamping ratio of nearly 1:1. This harsh working condition requires extremely high anti cracking performance. DC53 is a high carbon steel with poor anti cracking performance and is prone to collapse, so only 8566 die steel<\/a><\/strong>\u00a0can be used.<\/p>\n\n\n\n

\u00a08566 is a proprietary anti collapse steel developed by Yuhui Tool Steel<\/a><\/strong>, which mainly solves the problem of mold cracking; It has accumulated over a thousand cases in 5 working conditions, 6 major materials, and 7 major fields of stamping.<\/p>\n\n\n\n

The anti cracking performance of 8566 is four times that of high-speed steel SKH-9 and twice that of D2, with a hardness of58-60 HRC. It can solve the cracking problem that cannot be solved by high hardness tool steels<\/strong> such as D2, DC53, and SKH-9; Especially in harsh working conditions such as stainless steel stamping, sharp corner stamping, narrow edge stamping, punch width less than plate thickness, and stamping ratio less than 1:1, the cracking that cannot be solved by conventional tool steel<\/strong> is solved by using 8566 anti collapse steel.<\/p>\n\n\n\n

Mr. Lin, a customer from Shantou, punched 2.3-wide tweezers on 3mm thick 430 stainless steel. The punch width is smaller than the plate thickness, and the stamping ratio is less than 1:1. The DC53 punch is prone to corner breakage, but the lifespan of 8566 is three to four times that of DC53.<\/p>\n\n\n\n

Therefore, Mr. Hu’s continuous punching 2.3 acid washed plate, I-shaped 2.75-wide narrow edge punch, and DC53 always break, you should use 8566 anti collapse steel.<\/p>\n\n\n\n

The use of 8566 die steel<\/strong> for punch cracking is a double-edged sword in both old and new societies.<\/p>\n\n\n\n
