我厂主产品——低碳镀锌钢丝在小规格的半成品进入电镀工序以前,需经过水箱拉丝机进行拉拔,要增加3台这样的水箱拉丝机。是购买还是自行设计制造?为此我们对其进行了功能和经济效益分析。 水箱拉丝机的主要功能是拉拔钢丝并通过收线装置把钢丝缠绕起来。要求设备经久耐用,不易损坏,维修方便。 下面将两种水箱拉丝机的功能进行分析比较,如能满足以上所需功能,该方案即为可行。 国内有专门生产拉丝机的工厂,产品都是为生产多种线材而设计的,具有四种速度(300m/min、400m/min、530m/min、700m/min)的齿轮箱变速传动机构。我厂产品只用400m/min一种速度,不需变速功能。可见买专机的功能在我厂将产生过剩。由于买专机功能全,使得设备结构复杂,故价格较高。
Our factory’s main product, low-carbon galvanized steel wire, needs to be drawn by a water tank drawing machine before the small-size semi-finished product enters the electroplating process. It is necessary to add 3 such water tank wire drawing machines. Is it a purchase or self-designed manufacturing? For this we have conducted a functional and economic analysis. The main function of the tank drawing machine is to draw the wire and wind the wire through the take-up device. The equipment is required to be durable, not easily damaged, and easy to maintain. In the following, the functions of the two types of tank drawing machines are analyzed and compared. If the above required functions can be satisfied, this solution is feasible. There are factories specializing in the production of wire drawing machines in China. The products are designed for the production of a variety of wire rods and have gearbox transmissions with four speeds (300m/min, 400m/min, 530m/min, 700m/min). Our factory products only use a speed of 400m/min, without the need for variable speed functions. It can be seen that the function of buying a special plane will produce surplus in our factory. Due to the purchase of a full-featured machine, the equipment structure is complex, so the price is higher.
