Inclined precise cross wedge rolling forming device

Abstract

The invention relates to the technical field of metal plastic forming equipment, and provides an inclined precise cross wedge rolling forming device which is characterized in that rack units are symmetrically mounted on a base; the guide plate feeding units are symmetrically mounted above the base; the left and right molds are coaxially fixed by left and right shaft systems respectively; the driving unit is coaxially mounted on the shaft system unit to drive 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 mounted below the rolling mill to ensure synchronous opening and closing of the two racks; the lifting inclination unit provides the inclination angle needed by the rolling mill by controlling the lifting height. 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 product in a cross wedge mode. The device has the advantages of high rolling precision, convenience in die replacement, high automation degree and the like, can realize quick feeding and discharging by utilizing the dead weight of a rolled piece, remarkably improves the production efficiency, 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 an inclined precision cross wedge rolling forming device. 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] Most of the traditional cross wedge rolling mills are driven by cylinders, electric push cylinders, etc. The rolled pieces formed by cross wedge rolling can only fall out under the action of external force. If the forming temperature is high, the rolling stock will still maintain a high temperature after forming, resulting in a bad working environment of the driving device, and a set of independent driving device is required to provide power for the discharge, high cost, bad ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to at least overcome the disadvantages of slow discharge efficiency and high cost of existing cross wedge rolling mills, and provide an inclined type precision cross wedge rolling forming device, which can use its own gravity through the inclination angle set by the rolling mill base. The moment the rolled piece leaves the mold after the cross wedge rolling is completed, it quickly falls out of the rolling mill through the slide rail, which can achieve the goals of high rolling precision, rapid discharge, no need for additional power devices, cost saving, and high production efficiency.
