Problems solved by technology
Usually, the manipulator is used to feed the material or the turntable, but for the turntable and the workpiece size are larger than the press space, or for the multi-pass, multi-step ring workpiece, there is no better way to complete the forging
[0003] For large ring parts, if multi-pass forging is carried out, and when forging, multi-steps are used. Domestically, no better solution has been found. Using manipulators, etc., the operation is difficult, and the accuracy of forgings Difficult to guarantee

The invention discloses a multi-step multi-pass forging forming device and a construction method for a ring piece. The method includes S1, adjusting the positions of an outer guide roller, an inner guide roller and a driving roller on a turntable, and placing a first blank 12 to clamp On the left half-ring turntable; S2, the outer guide roller drives the blank to move on the left half-ring turntable and the right half-ring turntable, the press drives the upper anvil to reciprocate and press down, and forge the blank at the position of the lower anvil 4; In step S2, the blank is forged in sequence in a segmented manner. S3. The outer guide roller drives the forged blank from the right semi-annular turntable to the left semi-annular turntable, and repeats step S2 until the blank forging is completed. The invention can satisfy the forging of multi-pass and multi-step annular parts, and the forming device is simple and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of forging and forming, and more specifically relates to a multi-step and multi-pass forging forming device and a forming process for a ring piece. Background technique [0002] From the domestic point of view in the market, no better solution has been found for ring parts. Usually, manipulator feeding or turntable is used, but for the turntable and workpiece size larger than the press space, or for multi-pass, multi-step annular workpieces, no better method has been found to complete forging. [0003] For large ring parts, if multi-pass forging is carried out, and when forging, multi-steps are used. Domestically, no better solution has been found. Using manipulators, etc., the operation is difficult, and the accuracy of forgings Difficult to guarantee. Contents of the invention [0004] The first object of the present invention is to provide a new type of forging device, which can satisfy the forging of...
