Abstract

The invention relates to a large metal piece forming device, and particularly relates to a horizontal type bending machine used for forming an annular piece. The horizontal type bending machine solves the problems in the prior art that no large annular pieces can be formed, and the blank feeding and forming operations are difficult when the existing vertical type hydropress is adopted to form large annular pieces. The horizontal type bending machine comprises a rack, a first beam, a second beam, a working platform, a concave die, a convex die, a movable platform, a main hydraulic driver, two side hydraulic drivers, and four horizontal columns, wherein the working platform, the first horizontal beam, the second horizontal beam and the main hydraulic driver are horizontally arranged on the upper surface of the rack, a connected movable platform is arranged between a main drive rod and the convex die of the main hydraulic driver, a working platform is arranged between the first beam and the concave die, and side drive rods of the two side hydraulic drivers are respectively connected with the movable platform. The horizontal type bending machine provided by the invention is used for forming annular pieces.

Description

technical field [0001] The invention relates to a large metal piece forming equipment, in particular to a large metal ring piece forming equipment. Background technique [0002] Ring parts are widely used in metallurgy, petrochemical, aerospace, aviation and other industries. The existing manufacturing technologies of ring parts mainly include horse frame reaming, rolling and rolling method and steel plate cutting method. [0003] Horse frame reaming is to put the blank on the mandrel, hammer the blank with the upper anvil on the press or forging hammer, and produce elongation along the circumferential direction, so that the wall thickness of the forging is thinned, and the inner and outer diameters are increased at the same time, so that To meet the required diameter and size requirements, and then complete the manufacture of the cross section of the ring by turning and other mechanical processing methods, the disadvantages are large diameter deviation, uneven wall thickne...
