The object of this study is the technological process of manufacturing parts such as artillery shells using pressure treatment methods. The work is aimed at solving the current scientific and technical task to improve the technological processes for manufacturing parts such as cartridge cases based on the use of a tangential rolling operation with a friction tool, which ensures the production of hollow products with a bottom. Using the finite element method, modeling of the bottom rolling processes was carried out, which made it possible to establish the effective geometry of the processed workpieces and their heating temperature. Recommendations have been devised for the design of new technological processes for roughing bottoms, which consist of determining the wall thickness of the workpiece before deformation, the heating temperature of the workpieces, and the amount of supply of the workpiece to the friction tool. The resulting recommendations were verified by experimental studies. Roughing of spherical bottoms should be carried out for pipes with a relative wall thickness (D/s) in the range of 15...20, the homologous heating temperature should be 0.8, and the relative feed of the workpiece into the friction tool should be 0.9. Testing the established relationships under laboratory conditions confirmed the recommendations for changing the shape of spherical bottoms during the roughing process. The results of metallographic studies on full-scale products confirm the results of the theoretical study. It is recommended to use this technique for products that have an axial hole (artillery shells, hydraulic cylinders, etc.), which will allow removing axial defects in the bottom after drilling the axial hole. The results could be used at machine-building enterprises in the manufacture of dual-use parts

“…Xia et al [15] showed that a small sheet thickness and a large blank diameter increase wrinkling during the spinning process. Furthermore, Özer et al [16] conducted that the roller feed rate has a significant influence on the spinning result. It was shown experimentally that increasing the roller feed rate leads to a higher tendency to wrinkling.…”

Spinning process is a sheet metal forming technology used in the production of the symmetrical industrial parts. It is an efficient and inexpensive manufacturing process and has been widely used in various applications. In this research, new technique was developed to perform three different operations in the same stroke, namely conventional spinning, shear spinning (wall thickness reduction) and burnishing processes. This new technique has been performed by a new tool which consists of three stages, the first stage consists of two rollers to carry out conventional spinning process; the second stage includes two opposite balls to perform the process of shear spinning and the last stage comprises another two opposite balls to perform the process of burnishing. The burnishing balls differ from the shear balls in which that the burnishing balls have a spring behind the balls to decide the required burnishing load. Experimental work was conducted and confirmed the success of the presented technique. The response of the product quality and required load to process parameters such as rotational speed (46,76,150 and 230 rpm), axial feed (0.15,0.3,0.6 and 1.21 mm/rev) and burnishing load (20, 25 and 30 KN) was checked and clarified. The results showed that, the optimum condition for forming load occurred at rotation speed at 150 rpm, axial feed 0.3 rev/mm and burnishing load 25 KN.

“…Spinning with rollers does not require tools with unique shapes but needs repetitive processing because the diameter reduction rate per one processing is small due to the small area between the roller and tube, resulting in complex control of the roller position. In addition, the rigidity of the device is low due to the deformation of the roller struts when high stress is applied [11][12][13]. Therefore, Kanayama et al developed a new method-"Ball spin forming" [14].…”

This paper proposed a new ball spin forming equipment, which can form a reduced diameter section on the halfway point of a tube. The effects of forming process parameters on the surface integrity and deformation characteristics of the product were investigated. The proposed method can reduce the diameter in the middle portion of the tube, and the maximum diameter reduction ratio was over 10% in one pass. When the feed pitch of the ball die was more than 2.0 mm/rev, spiral marks remained on the surface of tube. Torsional deformation, axial elongation and an increase in thickness appeared in the tube during the forming process. All of them were affected by the feed pitch and feed direction of the ball die, while they were not affected by the rotation speed of the tube. By sending the ball die towards the fixed part of the tube or by increasing the feed pitch, torsional deformation and elongation decreased, and the amount of thickening increased. When the tube was pressed perpendicularly to the axis without axial feed, a diameter reduction ratio of 21.1% was achieved without defects using a ball diameter of 15.9 mm. The polygonization of the tube was suppressed by reducing the pushing pitch. The ball spin forming has a high advantage in flexible diameter reduction processing on the halfway point of the tube for producing different diameter tubes.
