设计简介
本次设计是设计F钉自动压扁机，该设备所要解决的问题是能够自动连续将圆钢丝压扁成要求厚度的扁钢丝以实现钢丝粘合成排，用于高效高速低成本的向排钉生产提供原料。
自动钢丝压扁机是钢材轧制技术和机械自动化技术的结合产物，该系统可在无人看管的情况下自行将钢丝连续压扁到规定厚度，并在断丝时自动停机，布线机构可将扁线均匀缠卷，钢丝接入设备就可自动开卷，自动校直，自动压扁，自动缠线。
在钢丝通过校直机构后进入轧辊压轧机构，设备采用两个轧辊将钢丝冷轧成扁丝，通过做往复直线运动的布线机构将钢丝均匀缠到辊子上，最终实现钢丝的自动开卷、校直、压扁和自动下料。
关键词 F钉 校直 压扁 冷轧 自动
Abstract
The graduation project is to design auto-squashing machine for F nail, the problem to be solved is to complete that a round wire will be automatically flatten into a flat wire which is satisfied with the thickness requirements in order to achieve the flat wire and wire rows for efficient high-speed nail to the row of low-cost raw materials reduction.
The auto-squashing machine applies rolled steel wire technology and machinery automation technology, the system can be left unattended when it squash the wire to the required thickness of straight and broken wires in automatic shutdown, and the wiring body can arrange the steel wire regularly when winding line. When we put the wire access to the device, it can automatically open the wire, automatically rectifying, automatically squashing, automatically winding line.
After the wire through the rectifying mechanism, it will be drawn into the pressure roll bodies which equipment use two rolls of cold-rolled steel wire to squash the round wire into a flat wire, and then the flat wire will be arranged regularly evenly wrapped around the wire roller through the wiring mechanism which do the back and forth movement in order to realize the ultimate realization of automatically opening automatically retifying, straightening, flattening and winding.
