Embodiment Construction

[0039] The embodiments of the present invention will be further described in conjunction with the accompanying drawings. This embodiment is used to illustrate the present invention, but not to limit the present invention in any way.

[0040] The straightening machine based on the present invention has completed overall design, and its roller system parameter setting is d1=230mm, t1=250mm, d2=340mm, t2=400mm, d3=280mm, t3=325mm, t4=400mm.

[0041] The thickness range of straightened products is 6-40mm, the straightened strength range is σs≤600Mpa, and the straightened width range is 1500-3000mm. When the product thickness is less than or equal to 20mm, use 15 rollers for straightening, and when the product thickness is greater than or equal to 20mm, use 7 rollers for straightening.

Abstract

This invention belongs to metal board band straightening technique field. It is a 15 rollers complex straightener. Problems by existing technique of thin format product with poor straightening quality and thick format straightening technique realizing hard and not high cogging down precision brought by irrational design of big and small roller series structure and cooperating parameter of 15 roller complex straightener. The 15 rollers complex straightener includes big roller series, small roller series, middle transition, structure and cooperation coefficient of the big and small roller series is optimized. Inclined wedge elevating mechanism is set at bottom part of the small roller series, adjusting mechanism is set at vertical position of middle transition roller. The roller structure and cooperation coefficient is reasonably optimized, and overall special structure and production technique is used to improve quality of the product, and useful life of the roller series is added, mechanical structure is optimized, so the investment is economized, and it is convenient to maintenance.

Description

technical field [0001] The invention belongs to the technical field of straightening metal strips, in particular to a 15-roller compound straightening machine. Background technique [0002] The purpose of straightening metal strips is to obtain finished products with high flatness. The 15-roller compound straightening machine is a strip straightening machine with wide straightening specifications, complex equipment structure and high cost performance. The biggest technical problem of the compound straightening machine is the design of the structure of the large and small roll system and the matching parameters. If the design is unreasonable, the straightening quality of thin-gauge products will be poor, and the straightening process of thick-gauge products will be difficult to realize, and the reduction accuracy will not be high. question. Contents of the invention [0003] The present invention aims at the unreasonable design of the large and small roll systems and matc...
