Embodiment Construction

[0023] The variable crown tension roller is used, and by controlling the fluid pressure in the sealing oil chamber between the mandrel and the bushing, the roller surface in contact with the strip can have a certain degree of convexity, thereby improving the metal strip. The purpose of shape defects.

[0024] like figure 1 As shown, the variable crown tension roll system 1 for pure stretching and straightening of metal strips includes a mandrel 101, a roll sleeve 103, at least one sealed cavity 104 formed between the roll sleeve 103 and the mandrel 101, and a hydraulic system The oil inlet pipeline 106 connected with the sealed cavity 104 is connected with the rotary joint 109 through the pressure transmission device 108, the oil return pipeline 105 connected with the sealed cavity 104 is connected with the rotary joint 109, and the rotary joint 109 is connected through the pipeline into the hydraulic system; the hydraulic system includes a hydraulic station 111 and a pressur...

Abstract

The invention relates to a metal strip pure extension straightening used convexity variable tension roller system, which includes a mandrel, a roller sleeve, at least one seal cavity formed between the roller sleeve and the mandrel, and a hydraulic system, wherein an oil inlet pipeline communicated with the seal cavity is connected with a swivel joint through a pressure transmission device; an oil return pipeline communicated with the seal cavity is connected with the swivel joint; the swivel joint is connected to the hydraulic system through a pipeline. Pressure-bearing liquid is transmitted to the seal cavity through the hydraulic system, pressure of the pressure-bearing liquid is changed to cause elastic deformation of the roller sleeve and deformation of the cladding layer, so that the convexity of the roller surface is formed; under the joint function of the tension and the convexity of the roller surface, the shape of the metal strip is adjusted and improved; the convexity variable tension roller system integrates two functions of tension stretching in strip straightening and adjustment in horizontal plate shape, and the real-time and on-line operation with a unit can be carried out.

Description

technical field [0001] The invention relates to a variable crown tension roller system for pure stretching and straightening of metal strips, which is suitable for straightening sets of wide-format thin metal strips and belongs to the technical field of metal strip finishing. Background technique [0002] In the metal processing industry, strip straightening is an important process in the finishing process, and it is the terminal link that controls the shape of the finished product. The strip straightening process has experienced technical development processes such as roller straightening, tension stretching straightening, and stretching bending straightening. At this stage, stretching, bending and straightening are the most widely used. In theory stretch bending straightening can achieve good straightening of the strip. [0003] However, due to the restriction of the mechanical structure of the straightening unit of the straightening unit, there will be different straigh...
