However, the current production process of high-gluten thin plates has many defects. The traditional casting of high-gluten thin plates consumes a lot of manpower, which is not conducive to the continuity of production, low production efficiency, and unevenness easily occurs inside the plate, which reduces the mechanical properties of the plate. Or under long-term load, there is still a potential risk of damage, which will affect the safety performance and service life of the equipment

Embodiment Construction

[0034] To produce plate thickness h 1 =8mm, rib height h 2 =16mm plate as an example:

[0035] Production parameters: blank thickness =30mm; the width of the blank b=400mm; the required plate thickness h 1 =8mm; Rib height h 2 =16mm; roll radius R=500mm; friction coefficient =0.35;

[0036] The rolling speed is 45mm / s. Firstly, the required groove with a depth of d=8mm is processed on the roll, and the billet is transported to the gap between the rolls through the lower conveying roller. In the rolling process, since the rolling deformation resistance and deformation temperature of the sleeve are much higher than that of the billet, all the deformation is completed by the billet during the deformation, and the deformation of the roll and the sleeve is negligible. After that, the blank thickness becomes the required plate thickness h 1 =8mm, and due to the action of the roller, the resulting height is h 2 =16mm rib body;

[0037] It is stipulated that the width of th...

Abstract

The invention belongs to the field of material forming, and particularly relates to a rolling forming process of a complex high-strength thin plate. Nowadays, there is a lack of production technology for preparing high-strength sheets, and it is impossible to achieve rapid mass production. This method selects a suitable roll sleeve to match the rolls, bites the billet, uses the grooves of the roll sleeve for rolling, and efficiently produces various types and shapes of reinforced rib plates according to production requirements. Improve the overall structural strength, including the lower conveying roller, the upper positioning roller, the roller, the roller sleeve and the roll forming method. The invention is a rolling forming method for safely and rapidly preparing high-strength thin plates, liberates manpower, realizes semi-automatic and batch production, improves production efficiency, realizes green production, and has wide application prospects.

Description

technical field [0001] The invention belongs to the field of metal plastic forming, and in particular relates to a rolling forming process of complex high-strength thin plates. Background technique [0002] High-reinforced plates are widely used. Many components such as aerospace and weaponry have high strength and toughness requirements while pursuing lightweight, so it is necessary to have reinforcing ribs on the plates. However, the current production process of high-gluten thin plates has many defects. The traditional casting of high-gluten thin plates consumes a lot of manpower, which is not conducive to the continuity of production, low production efficiency, and unevenness easily occurs inside the plate, which reduces the mechanical properties of the plate. Or under long-term load, there is still a potential risk of damage, which affects the safety performance and service life of the equipment. [0003] How to realize high efficiency and automatic production while im...
