辊模拉丝设备工作原理是什么？What is the working principle of roller mould wire drawing equipment?

辊模拉丝设备在我们日常生产中有着很重要的作用，对于新手来说，我们首先要了解辊模拉丝设备的工作原理，才能在工作中正确地操作机器生产产品。小编现在就为大家来介绍一下辊模拉丝设备的工作原理：

Roller die mould wire drawing equipment plays a very important role in our daily production. For novices, we must first understand the working principle of roller die mould wire drawing equipment in order to correctly operate the machine to produce products during work. Now, the editor will introduce to you the working principle of roller mould wire drawing equipment:

辊模拉丝设备的工作原理看似复杂，其实也比较简单，有多个拉拔头组成的小型的连续生产设备，通过逐级拉拔，可以一次性地把钢丝冷拉到所需的规格，所以工作效率比较高。但是，由于通过每一级的拉拔后，钢丝的线径发生了变化， 所以每个拉拔头工作线速度也应有变化。  当然了，在机器工作的期间，辊模拉丝设备根据拉模配置的不同，各个拉拔头的拉拔速度也要变化。拉拔速 度的基准是每个时刻通过拉模的钢丝的秒流量体积不变， 即使以下公式成立：π r2×v1= π r2×v2 r：进线钢丝的直径 v1：进线钢丝的线速度 r： 出线钢丝的直径 v2：出线钢丝的线速度 拉丝机的各个拉拔头的工作速度就是基于以上的公式， 保证各个 拉拔头同步运行。

The working principle of the roller mould wire drawing equipment seems complex but it is actually relatively simple. It has a small continuous production equipment composed of multiple pulling heads. Through step-by-step drawing, the steel wire can be cold-pulled to the required specifications at one time, so the working efficiency is relatively high. However, since the wire diameter of the steel wire changes after pulling through each stage, the working line speed of each pulling head should also change. Of course, during the machine operation, the pulling speed of each pulling head must also change depending on the mould configuration. The reference of the drawing speed is that the second flow volume of the wire passing through the pulling die remains unchanged at each moment, even if the following formula is true: π r2×v1= π r2×v2 r: diameter of the incoming wire v1: linear speed of the incoming wire r: diameter of the outgoing wire v2: linear speed of the outgoing wire The working speed of each pulling head of the wire drawing machine is based on the above formula to ensure that each pulling head operates simultaneously.

但是， 以上的说明是基于理想状态的稳态工作过程， 由于机械传动的误差以及机械传动的间隙， 还有在起动、 加速、 减速、停止等动态的工作过程中，各个拉拔头就无法保持同步，所以，大多数的直进式拉丝机上都有张力传感器， 动态测量各个拉拔头间的钢丝的张力，再把张力转换成标准信号，用这个标准信号反馈给调速变频器，变频器用这个信号作闭环 PID 过程控制，在主速度上叠加上 PID 计算的调整量，保持各个张力检测点的张力恒定，也就保证了直进式拉丝。 一般的辊模拉丝设备我们将采用引进、吸收、消化技术开发生产的高档拉丝机，适宜 拉拔Ф 14mm 以下的各种金属线材，适用拉拔范围有弹簧钢丝、制绳钢丝、帘线钢丝、胎圈钢丝、药丝焊丝、气保焊丝、铝包钢丝、预应 力钢丝、胶管钢丝及各类低、中、高碳钢丝等等。以上信息希望能帮助到你。

However, the above description is based on the ideal state. During the steady-state working process, mechanical transmission error and mechanical transmission interval, as well as dynamic working processes such as start, acceleration, deceleration, and stop, each pull head cannot remain synchronized. Therefore, most vertical wire drawing machines currently have tension sensors that dynamically measure the wire tension between each pull head and convert the tension into a standard. This standard signal is used to feed back to the speed-regulating inverter, which converts this signal into closed-loop PID process control. This is an advanced traction machine developed using introduction, absorption and digestion technologies, which can pull out various metal wires below 14 mm. Spring wire, rope wire, string wire, tire coil wire, pharmacist wire, gas-protected welding wire, aluminum-clad wire, prestressed wire, hose wire and various types levels of low, medium and high wires.etc...
