Coating hot forming steel part and preparation method thereof

The invention relates to the technical field of stamping forming manufacturing of coating hot forming steel, in particular to a coating hot forming steel part and a preparation method thereof. The method comprises the following steps: carrying out temperature detection on different areas of the plated hot-formed steel plate, and determining the average temperature of each area; according to the average temperature, whether an area corresponding to the average temperature needs to be pre-cooled or not is judged, then stamping and pressure maintaining are conducted, and a coating hot forming steel part is obtained; wherein if the average temperature is higher than a set temperature, it is judged that an area corresponding to the average temperature needs to be pre-cooled, and the use amount of a cooling medium used in pre-cooling is controlled; the set temperature is not higher than the coating melting temperature of the coating hot forming steel. The technical problem that an existing zinc coating hot forming
