Abstract

The invention belongs to the technical field of rolling equipment, and particularly relates to a roller column rotary rolling machine. The technical problems that in the existing ball spinning process, material plastic accumulation is likely to be generated in an unformed area, and the spinning yield is low are mainly solved. According to the technical scheme, the roller column rotary rolling machine comprises a bottom plate and a core mold driving mechanism and further comprises a feeding mechanism, an angle adjusting mechanism and a pressing-down adjusting mechanism, the feeding mechanism isarranged on the upper plane of the bottom plate, the angle adjusting mechanism and the pressing-down adjusting mechanism are arranged on the upper plane of a feeding platform in the feeding mechanism, and the core mold driving mechanism is arranged at one end of the upper plane of the bottom plate. The rotary rolling machine can change the rotary rolling angle and the rolling reduction of rollercolumns, can ensure that the rolling reduction of each roller column is the same, and has the advantages of being simple in structure, compact in equipment, easy and convenient to operate and capableof easily achieving adjustment of the rotary rolling angle.

Description

technical field [0001] The invention belongs to the technical field of rolling equipment, and in particular relates to a roller column spinning mill. Background technique [0002] Spinning is one of the main technological means of steel pipe forming. For precision thin-walled pipes, ball spinning is often used for processing at this stage. Ball spinning is a continuous local plastic forming process using balls as a deformation tool. It has the advantages of small deformation area and large forming force, but at the same time, due to the small unformed area, during the spinning process, the unformed area is prone to material plasticity. Accumulation, resulting in low spin rolling yield. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the defects existing in the existing ball spinning, and to provide a roll rolling machine, which can change the rolling angle and reduction of the rolls, and can ensure that the reduction of each roll is the ...
