Abstract

The invention relates to the technical field of metal plastic forming equipment, and provides a forming device capable of achieving precise cross wedge rolling. The guide plate feeding units are symmetrically mounted above the base about the central axis; the left and right dies are coaxially fixed by the left and right shaft systems respectively; the driving unit is coaxially installed on the shaft system unit and drives the mold to rotate. The roller spacing adjusting unit is installed above the rolling mill in a penetrating mode, and the die spacing is adjusted by controlling the opening and closing degree of a rack. The synchronous units are symmetrically installed below the rolling mill, and synchronous opening and closing of the two racks are guaranteed. A blank reaches a designated position through the guide plate feeding unit, the roller spacing is adjusted through the roller spacing adjusting unit, and the driving unit provides rolling power to roll the blank into a needed product in a cross wedge mode. The precise cross wedge rolling device has the advantages of capability of realizing precise cross wedge rolling, high rolling mill rigidity, convenience in die replacement, compact structure, high production efficiency and the like, can be used for precise cross wedge rolling forming of small and medium-sized shaft parts, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of metal plastic forming equipment, in particular to a forming device that can realize precise cross wedge rolling. Background technique [0002] As an efficient metal plastic forming process, cross wedge rolling is recognized as an important part of today's advanced manufacturing technology. Cross wedge rolling is widely used in the production of shaft parts blanks such as automobiles, train axles, and internal combustion engines. [0003] The existing cross wedge rolling technology is still widely used in the blanking stage of parts, the rolling precision is not high, and secondary processing is still required, which limits the large-scale promotion of the cross wedge rolling technology. Therefore, there is an urgent need to overcome the deficiencies of existing equipment and processes, and to invent a forming device and process that can realize precise cross wedge rolling.
