基于双曲面冷拉型钢棒材矫直机设计

摘要：本文从研究矫直棒材的变形机理入手，设计出一台七辊矫直机，并对矫直变形理论及矫直工艺进行了研究。所设计的矫直机采用悬臂式机架结构，该结构为当前矫直机的主体形式，具有换辊方便，操作调整灵活等优点。其共有7个辊系，分为上下两行，辊距相等，辊轴上下两行交错排列，且平行。
在文中介绍了矫直机的基本参数的设计过程和相关参数的选取。从矫直产品的规格出发，依据矫直的基本原理，结合现代设计理论，完成了设计任务，达到了设计目的。其主体设计为辊系上下调整机构、左右窜动调整机构、压下机构和机架等机构，同时对相关的参数设计进行了初步研究。

Abstract: Design on a seven rolls Straightening Machine and Technology of straightening section. Beginning of researching on the mechanism of researching on the mechanism of deformation of the straightening section, seven rolls straightening machine is designed are successfully trial-produced. In the meantime through research is done about the theory of straightening technology. In this article the straightening machine designed is to belong to cantilever frame structure, the normal form of straightened for now. Cantilever structure operation convenient for changing rolls, and adjust flexibly. It has seven roll systems totally, divided into two lines; rolls are in the equal distance up and down, the rollers are arranged fluctuation in two line crisscross, and paralleling.
In this paper introduces the basic parameters of the straightened the design process and related parameters selection. From the specifications of the products, the straightening based on the basic principle of straightening, has completed the design task, and reaches the design purpose. The main design is the roll system for up and down, the adjusting mechanism of dynamic adjusting mechanism, press agencies and frame institutions.

Keywords: Mechanism of deformation straightening; Seven-roll bar straightened; Machine the structure principle; steel bar straightening machine
