Abstract

The invention discloses a hot rolling device for machining and belongs to the field of machining.The hot rolling device for machining comprises a workbench, a guide roller is rotationally connected to the workbench, a mounting block is slidably connected to the workbench, and a first pressing roller is rotationally connected to the mounting block; a second pressing roller is rotatably connected to the portion, located on the lower portion of the first pressing roller, of the workbench, a first bevel gear is coaxially and fixedly connected to the end of the first pressing roller, a transmission gear and a second bevel gear are coaxially and fixedly connected to a rotating shaft, a mounting plate is fixedly connected to the workbench, and a threaded rod is coaxially and fixedly connected to the bottom of a mounting rod; and the threaded rod is in threaded connection with the mounting plate. When a mounting rod rotates, a fourth bevel gear and a fifth bevel gear are alternately engaged with a second bevel gear and a third bevel gear together, and the mounting rod drives a first pressing roller and a second pressing roller to be close to each other, so that the effects that rough rolling and finish rolling can be operated on the same equipment, and the space is saved are achieved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a hot rolling device for machining. Background technique [0002] Hot rolling is relative to cold rolling. Cold rolling is rolling below the recrystallization temperature, while hot rolling is rolling above the recrystallization temperature. Rolling, then trimming, and straightening into a steel plate, this is called hot rolling, which can significantly reduce energy consumption and reduce costs. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys, that is, the coarse grains in the casting state are broken, and the cracks heal significantly, reducing or eliminating casting. Defects, the as-cast structure is transformed into a deformed structure, and the processability of the alloy is improved. [0003] When ho...
