张拉机全自动控制系统设计

Design of Automatic Control System for Tensioning Machine

预应力混凝土管桩的生产过程,其中预应力是对管桩抗弯性能的一个最重要的参数,预应力的施加是由一台张拉机的设备来控制,以前采用传统的标尺来控制管桩长度的拉伸量,员工观看标尺刻度到达规定的标准值时,人手控制停止的方式来决定一条管桩的预应力,这样对操作员工的要求较高(不同管桩的长度的拉伸值要相应的改变),控制产品的精度差,产品的质量得不到保证。针对生产现场的实际情况,合理设计张拉机的全自动控制系统,对员工操作的要求降低,全自动控制系统精度得到保证,从而保证产品质量的稳定,提高公司的生产效益。

The production process of prestressed concrete pipe pile,the prestressed is the bending capacity of pipe pile,one of the most important parameters of the prestress is applied by a tensioning machine equipment to control,used to adopt the traditional ruler to control the amount of stretch pipe pile length,when staff scale label arrived at specified standard,the way of hand control to stop to determine a prestressed pipe pile,so it is high requirement of operation staff(different length of the pipe pile the tensile values corresponding need to change),the control precision of the product is poor,can not guaranteed the product quality and the quality unstable.According to the actual situation of production site,the reasonable design of tensioning machine automatic control system can reduce requirement for operators,full-automatic control system accuracy is guaranteed,thus to ensure the stability of product quality,and improve the production efficiency of the company.
