Abstract

The invention relates to a method and equipment for processing metal material, particularly to a technology and equipment for rolling superlarge-diameter aluminium alloy ring pieces. The method and the equipment are characterized in that the rolling technology comprises the following steps: A. calculating parameters: calculating technical control parameters including the dimensions of a roughcast, the rolling linear speed, the radial-axial rolling force during various stages, the enlargement rate of the ring pieces, the radial-axial feed speed, the external diameter of the ring pieces, the height of the ring pieces and the wall thickness of the ring pieces according to the dimensions of a product ring; B. inputting parameters: inputting the various technical control parameters into a numerical control ring rolling mill computer according to the calculation results; C. numerically controlled rolling: fully automatic control is adopted during the rolling process. A radial rolling mechanism and an axial rolling mechanism are connected on the chassis of the equipment; and the radial rolling mechanism is connected with a king roller drive mechanism (1) and a core roller mechanism (7). The axial rolling mechanism is connected with an axial roller drive mechanism (14). The technology and the equipment for rolling superlarge-diameter aluminium alloy ring pieces lead to smooth rolling process and high-precision of the dimensions of product rings.

Description

technical field

[0001] The invention relates to a metal material processing method and equipment, in particular to a rolling process and equipment for super-large aluminum alloy rings. Background technique

[0002] Aluminum alloy materials are high in strength and light in weight, and are widely used in my country's aviation and aerospace industries. However, the forging temperature range of aluminum alloy materials is narrow, and some materials are soft and sticky; some materials are hard and brittle, which makes the process of producing aluminum alloy ring parts more difficult. The traditional method of processing aluminum alloy ring parts in China is mostly forging by free forging on hydraulic presses, which has poor precision, low efficiency, high labor intensity, low material utilization, limited outer diameter of ring parts, and the maximum diameter of billet making capacity. In addition, the larger the diameter of aluminum alloy ring parts is, the more difficult it i...
