Rolling feed curve control and checking method for inverted U-shaped multi-section wire core roller of aviation rectangular ring piece

Abstract

The invention discloses a rolling feed curve control and checking method for an inverted U-shaped multi-section wire core roller of an aviation rectangular ring piece. The rolling feed curve control and checking method comprises the steps of feed curve planning, speed planning, time proportion planning, rolling time calculation, generation of an inverted U-shaped multi-section wire core roller feed curve, generation of a ring piece outer diameter-time curve, generation of a ring piece outer diameter growth speed-time curve and construction of a rolling parameter system. The method is applied to aviation material rectangular ring rolling production, and the requirements for the rolling feeding speed in the initial rolling biting stage, the rolling speed in the aviation material ring piece main rolling stage and the ring piece rolling speed in ovality rolling production in the ring piece finish rolling stage in the actual rolling process are met; and a basis is provided for manual rolling operation of a rolling operator, so that batch stable rolling of the ring pieces is improved, and even the feed curve of the inversed U-shaped multi-section wire core roller can meet the requirement of automatic rolling production of the ring pieces on a rolling curve.

Description

technical field [0001] The invention belongs to the technical field of ring rolling forming of aviation ring forgings, and in particular relates to a method for controlling and checking the rolling feed curve of reverse U-shaped multi-segment core rolls of aviation rectangular rings. Background technique [0002] Aeronautical ring forgings are often rolled by the ring rolling process. In the design process of the ring rolling process, the total amount of rolling deformation for each fire is mainly designed and controlled, that is, the size of the billet for each fire and the rolling completion are specified. Dimensions, the rolling process of individual hard-to-form aerospace material ring forgings needs to control the maximum growth rate of the outer diameter of the ring during each rolling process, but there is no detailed regulation for each rolling process. [0003] In the actual production process of aerospace ring forgings rolling, the rolling operator manually control...

Problems solved by technology

However, this invention does not take into account the actual situation of ring rolling production and the rolling forming rules of aerospace materials, and the set constant ring growth rate cannot be used for ring rolling control in the actual production process of ring forgings.
