Horizontal type two-roller rolling mill with rapid roller changing function

Abstract

The invention relates to a horizontal type two-roller rolling mill with a rapid roller changing function. The horizontal type two-roller rolling mill comprises a rack and rolling units, wherein each rolling unit comprises a left roller support assembly, a roller assembly and a right roller support assembly which are sequentially arranged in the horizontal direction, each left roller support mechanism comprises a left roller seat, a left bearing and a left shaft sleeve which are sequentially arranged from outside to inside, the left shaft sleeve is hollow inside, the end, facing the roller assembly, of the left shaft sleeve extends to form an inserting block, and the left roller seat is embedded into a mounting groove in a sliding manner; each roller support assembly comprises a right roller seat, a right bearing and a right shaft sleeve which are sequentially arranged from outside to inside, the right shaft sleeve is hollow in side, and the right roller seat is embedded into the mounting groove in a sliding manner; and two ends of each roller assembly are coaxially inserted into the corresponding left shaft sleeve and right shaft sleeve in a sliding manner, the roller assemblies are provided with inserting grooves matched with the inserting blocks, and therefore, the roller assemblies can be rapidly disassembled and can be changed.

Description

technical field [0001] The invention relates to the technical field of rolling mills, in particular to a fast roll-changing horizontal two-rolling mill. Background technique [0002] A rolling mill is a device for plastically deforming metal. [0003] The patent with the existing notification number CN205587427U discloses a roll mechanism of a vertical rolling mill, which includes a stand and a roll support arranged on the stand. The upper end of the roll support is provided with a motor, and the output end of the motor is from top to bottom. There are bevel gearbox joints, universal joints, universal joint intermediate shafts, spline joints, spline sleeves and roller system components in sequence. [0004] There are following defects in the above-mentioned prior art scheme: [0005] Combined with the disclosure of the drawings, it is obvious that the roll assembly can be subdivided into the roll assembly used for roll processing and the bearing housings arranged at both e...

Problems solved by technology

[0005] Combined with the disclosure of the attached drawings, it is obvious that the roll assembly can be subdivided into the roll assembly used for roll processing and the bearing housings arranged at both ends of the roll assembly. When the roll assembly needs to be disassembled and replaced, the end of the roll assembly and the bearing There is a large friction between them, and after repeated disassembly and assembly, it will cause problems such as bearing deformation and damage
