Beschreibung
Zusammenfassung:	A roll-bending forming method for a hollow inequilateral profile frame, comprising the following steps: S1, cutting out a blank to be roll-bent from a base material according to requirements; S2, performing filler treatment on gaps in the blank to be roll-bent; S3, performing pre-roll-bending forming on the blank undergoing filler treatment to obtain a pre-finished product; S4, performing filler removal on the pre-finished product and then performing quenching treatment to obtain a semi-finished product; S5, performing filler treatment on gaps in the blank of the semi-finished product; S6, performing supplementary roll-bending forming on the semi-finished product; and S7, performing filler removal on the product obtained in step 6, and cutting the waste to obtain a finished product. According to the structural characteristics of hollow profile frame parts, a roll-bending heating treatment forming process is reasonably designed, a mold structure is optimized and improved, a mold having two vertical edges of di
