What is the ruling regarding a man telling his wife: "You are like my daughter," with the intention of making her forbidden to him for a specific period as a means of punishing her?

A husband's statement to his wife, "You are like my daughter," is an equivocal expression (kinaya) that can imply a Zihar (a pronouncement by a husband that his wife is unlawful to him as his mother or sister) or something else. If the husband intended to prohibit his wife to himself for a specific period, then this is a temporary Zihar. The majority of scholars hold that temporary Zihar is valid. If the specified period expires, the wife becomes lawful to him again without requiring expiation. However, if he has intercourse with her before the completion of the specified period, he is required to offer the expiation for Zihar.
