Abstract

The invention discloses a heat-assisted variable-section roll forming machine system and a method thereof. According to the system, a variable-section roll forming system comprises an uncoiler, a straightening machine, a feeding machine, a variable-section roll forming unit and a flying shear machine sequentially according to the machining sequence of plates, an electromagnetic auxiliary heating system comprises a high-frequency furnace and a temperature sensor, a computer control system comprises a variable-section roll forming control system and the electromagnetic auxiliary heating system, the uncoiler, the straightening machine, the feeding machine, the variable-section roll forming unit and the flying shear machine are connected with the variable-section roll forming control system, the high-frequency furnace and the temperature sensor are connected with the electromagnetic auxiliary heating system, and the variable-section roll forming control system is in communication connection with the electromagnetic auxiliary heating system. By the aid of the system and the method, the work hardening phenomena of plates made of magnesium alloys, aluminum alloys and high-strength steels can be reduced, the forming limit of plates can be improved, the deformation resistance can be reduced, the uniformity, the toughness and the malleability of material flowing can be improved, and the forming performance of plates can be improved.

Description

technical field [0001] The invention relates to the technical field of roll forming technology and equipment, in particular to a heat-assisted variable cross-section roll forming machine system and a method thereof. Background technique [0002] The cross-sectional shape of the current roll-formed products is becoming more and more complicated. The conventional roll-bending process encounters insurmountable difficulties in the production of roll-bent profile products such as magnesium alloy, aluminum alloy and high-strength steel. During the forming process, due to the work hardening of the plate, its strength and hardness increase, and its plasticity and toughness decrease, which brings difficulties to the continuous plastic deformation of the plate. When the maximum deformation degree is reached, it is easy to cause the profile to break, making the forming impossible. keep going. [0003] Taking aerospace equipment as an example, the primary problem with this type of stru...
