Multifunctional aluminum profile stretch-bending forming die and stretch-bending forming process

Abstract

The invention relates to a multifunctional aluminum profile stretch-bending forming die and a stretch-bending forming process. The multifunctional aluminum profile stretch-bending forming die comprises a tool bottom plate and multiple radial radian positioning block slideways fixedly installed on the tool bottom plate, radian positioning blocks are installed on the radian positioning block slideways in a sliding manner, and the radian positioning blocks comprise arc-shaped positioning blocks and fine adjustment positioning blocks. Bolt connecting holes are formed in the longitudinal directionsof the fine adjustment positioning blocks, a height adjusting nut is slidably installed in each T-shaped groove in the sides, opposite to the fine adjustment positioning blocks, of the arc-shaped positioning blocks, and screw rods are arranged in the fine adjustment positioning blocks in a penetrating manner. Radian fine adjustment nuts corresponding to the height adjustment nuts are installed atthe positions, on the sides, opposite to the arc-shaped positioning blocks, of the fine adjustment positioning blocks, of the screw rods in a threaded manner, and fastening nuts are installed at thepositions, on the sides, away from the arc-shaped positioning blocks, of the fine adjustment positioning blocks, of the screw rods in a threaded manner. The problems that an existing high-strength aluminum alloy angle aluminum profile stretch-bending tool is simple in design, free of universality, high in tool cost, large in manual mounting and dismounting workload and prone to influencing tool precision are solved.
