Abstract

The invention discloses a processing device and a processing method for an inner rib tube, and belongs to the field of material plastic processing. According to the processing method applying the processing device for the inner rib tube, an elastic sliding form is rolled on a tubular blank, so that an inner rib can be formed at one time in a tube body, and in the processing process, the tubular blank is locally deformed when sliding form teeth of the elastic sliding form are in contact with the tubular blank, at the same time, wall thinning and inner rib filling are completed. The processing method is easier to implement since required external force is smaller. The processing method has the characteristics that the processing efficiency is high, the use range is wide, the weldless qualityis high, material is saved, and the production cost is low.

Description

technical field [0001] The invention belongs to the field of plastic processing of materials, in particular to a processing device and a processing method of an inner rib cylinder. Background technique [0002] The large thin-walled cylinder with longitudinal internal ribs is the main component of the launch vehicle fuel tank and engine casing. This kind of parts has the characteristics of large diameter, thin wall thickness, high processing precision and high quality requirements, so it is extremely difficult to manufacture, which is a typical neck-holding technology in the aerospace industry. The large thin-walled cylinders of heavy rockets generally use T-shaped, L-shaped inner ribs with complex cross-sections, and the processing difficulty is further increased compared with ordinary rectangular inner ribs. [0003] At present, there are only two effective methods for processing such parts at home and abroad, the process route of "roll bending forming + chemical milling ...
