Problems solved by technology

When the traditional rolling machine rolls metal or alloy, the extrusion stress generated by rolling is unevenly distributed on the rolled material, which often causes the rolled material to be distorted and deformed during rolling. In this way, on the one hand, the uneven change in the shape of the rolled material will easily lead to a large difference in the internal structure of the rolled material, which will easily affect the subsequent experimental observations. On the other hand, due to the twisted deformation of the rolled material, the roll will The surface stress is evenly distributed, which can easily damage the surface of the roll, which will lead to uneven surface of the rolled material and reduce the service life of the roll machine

Abstract

The invention relates to a rolling mill used in a lab, in particular to a rolling mill with a correction device. The rolling mill comprises a power device, an upper roller, a lower roller and a protection sleeve, wherein the upper roller and the lower roller are arranged in a parallel and up-down mode, the protection cover is used for containing roller sleeves at the end portions of the rollers, and a hand wheel which can adjust operation positions of the upper roller and the lower roller is arranged on the protection cover. The rolling mill is further provided with a support platform, wherein the correction device is arranged on the support platform which is mainly composed of a fixed clamping board and a movable clamping board both of which can be buckled in a mutually stagger mode, the fixed clamping board is fixed on the support platform, and the fixed clamping board and the moveable clamping board which are buckled to form a correction section of the working areas of the upper roller and the lower roller. The space areas, in or out of which mill bars can get in or out, of the rollers can be corrected, and therefore shapes of the mill bars can be corrected, and surface damage of the rollers can be reduced.

Description

technical field [0001] The invention relates to a roll machine for laboratory use, in particular to a roll machine with a straightening device. Background technique [0002] The roll machine is a tool for plastically deforming the rolled material. It uses the pressure generated by a pair or a group of rolls to roll the rolled material. It mainly bears the dynamic and static loads, wear and temperature changes during rolling. There are many types of roll machines. According to the classification of the rolls used, the types of rolls commonly used in roll mills are cast steel rolls, cast iron rolls and forged rolls. There are also a small amount of hard alloy rolls on profile rolling mills. Laboratory roll machines are mostly used for rolling experimental metal or alloy samples to obtain samples of required thickness and width, and to realize the measurement, testing, and observation of the comprehensive properties of samples. When the traditional rolling machine rolls metal ...
