With the extension function of the staggered pressure wheel bar straightening machine, comprises a traction mechanism, located in front of the straightening machine is located in the rear traction mechanism of straightening mechanism and extension in straightening feeding mechanism of extension mechanism of rear end; traction mechanism is composed of a traction wheel frame 1, traction wheel 2, traction wheel 3 and a traction wheel adjustment component 4; extension mechanism by straightening straightening wheel frame 7, two and 8 straight round panel straightening wheel adjusting component 9; feeding mechanism comprises a feeding wheel frame 12 and a lower feeding wheel 13, the upper feeding wheel 14 and the feeding wheel adjustment component 15. During operation, the traction wheel which is connected with the prime mover is clamped with the steel bar which is continuously advancing, and the straightening wheel of the straightening and extending mechanism is repeatedly straightened and stretched by bending and pressing. The utility model has the advantages of one machine, two energy, simple operation, etc., greatly simplifies the mechanism of the equipment, saves the steel used for the equipment, reduces the manufacturing cost of the equipment, and reduces the energy consumption of the equipment operation.

技术介绍
根据我国最新审定修改的《混凝土结构工程施工质量验收规范》5、3、2A条的规 定,以盘卷形式供货的钢筋,调直后允许单位长度重量负偏差为<8-10%。即盘卷供货的 HRB300以下强度级的钢筋调直后允许单位长度重量负偏差为< 10% ;盘卷供货的HRB335以 上强度级的钢筋调直后允许单位长度重量负偏差为< 8%。该规定的制订,是基于盘卷钢筋 在调直加工时使之产生一定延伸的情况下,钢筋的强度会稍有提高,而其它物理指标没有 多大变化,而且在国家标准的范围内。因此,盘卷钢筋在调直加工时使之产生一定延伸,不 但可以提高建筑质量,还可大量节约建筑用钢材。因盘卷要经钢筋调直机调直加工后才能用于建筑混凝土内,而目前钢筋调直机的 结构有两种1、旋转框架式钢筋调直机。运行时,调直块或调直辊绕着被牵引经过的钢筋作螺 旋运动。如果将调直块或调直辊在钢筋上压得过量,则调直出来的钢筋会成麻花形的扭曲, 这种结构的调直机只能将钢筋调直而无法使之延伸。2、压轮式钢筋调直机。其包括由相互错开的两排调直轮、两排调直轮轴和调直轮 架组成的压轮式调直机构,相互错开的两排调直轮通过调直轮轴安装在调直轮架上,下面 一排调直轮通过牵调直轴与原动机的动力输出组件相连,即下面一排调直轮全为主动轮, 上面一排调直轮全为被动轮,被加工的钢筋在主动轮与被动轮中间,被动轮通过调整机构 将搁在主动轮上的钢筋压弯。主动轮、被动轮均是沿钢筋轴向转动,运行时钢筋在主动轮的 驱动下不停地前进,而众多的被动轮压在 ...
