Double-rotating-shaft cantilever type skew rolling mill

Abstract

The invention relates to the technical field of metal plastic forming processes and equipment, and provides a double-rotating-shaft cantilever type skew rolling mill. The skew rolling mill is mainly composed of a base, a cantilever type roller system, a gear synchronizing mechanism, a radial reduction mechanism, machine frames, a material guiding unit and inclination angle adjusting mechanisms, wherein the cantilever type roller system is tensioned by bolts on the backs of the machine frames of the rolling mill, and the roller system inclination angle adjustment is realized through the inclination angle adjusting mechanism below bearing seats; the two machine frames which are supported by double rotating shafts of the rolling mill base; synchronous alignment and reduction are realized on the two machine frames through the gear synchronizing mechanism, and the center line of the vertical direction of the rolling mill is ensured to be fixed; the radial reduction mechanism is arranged above the machine frames, and the roller distance adjustment of two rollers is realized by rotating reduction nuts; and the inclination angle adjusting mechanisms are arranged at the corners of the machine frames so that the space can be saved, moreover, the action line is long, and the high-precision adjustment of the inclination angle of the roller system can be realized. The double-rotating-shaftcantilever type skew rolling mill is ingenious in design, has the advantages of convenience in roller replacement, fixation of the vertical center line of the rolling mill, convenience in installationand adjustment and the like, and is suitable for the production of large-scale small-diameter steel balls.

Description

technical field [0001] The invention relates to the technical field of metal plastic forming technology and equipment, in particular to a double-shaft cantilever skew rolling mill. Background technique [0002] Steel balls are widely used in industrial production, especially in the field of mine beneficiation. The data shows that the annual consumption reaches millions of tons. Therefore, with the increasing application and demand of steel balls, the production of steel balls The requirements of manufacturing technology are also increasing day by day. Low consumption, cleanliness, high quality and high efficiency are the development direction of steel ball production in the future. [0003] At present, there are two main ways to produce steel balls in our country. One is cold heading. Although the production volume is considerable, cold heading has serious wear on the inner cavity of the mold. more serious. The other is steel ball casting. The biggest advantage of the cast...

Problems solved by technology

Therefore, the application of cross-rolling steel ball technology is the trend of steel ball production in the future, but most of the cross-rolling mills currently have disadvantages such as complicated installation and adjustment steps, cumbersome roll changing steps, low adjustment accuracy, and single production products.
