The invention relates to online continuous punching method and equipment in cold roll forming. The method includes the steps that information of products to be produced is input; in production, after a punching die and a gap punching die act each time, the die which acts after next feeding is finished is determined; the feeding length a of a next hole and the feeding length b of a next gap are calculated according to the length of fed materials and the information of the products to be produced, the two distance values are compared, if the a is smaller, the punching die is the die which acts after next feeding is finished, and if the b is smaller, the gap punching die is the die which acts after next feeding is finished. By means of the mode, the products of various specifications can be produced automatically and continuously.
