$5 DIY Hot Wire Foam Cutter

基本上我是个疯子,他喜欢用最奇怪的方式去思考,他做了他想做的事,也让别人做了那些事。看看我的疯狂项目,如果你愿意的话,一定要跟着我。

嘿,伙计们,很久以来,我一直没有写过一本教科书。
在这本教科书中,I will show you how to make a StyroFoam Cutter using things that are lying in your home.


Styrofoam cutter基本上是用欧姆定律加热电线的,其中热量等于I2r,其中
I is the current flowing throw the wire and R is the resistance.
现在镍铬合金的电阻率范围为1.10×10−6Ωm至1.50×10−6Ωm,沸点非常高(~1400°C)。

顺便说一句,如果你喜欢这个教科书,请确保你按了投票按钮,让我在塑料比赛中获胜。

Step 1: Cut the PVC Pipe

We first start by cutting a PVC pipe,我有一个2英尺长的,所以我需要剪成以下的长度

  • 12 " long
  • 4“长”

步骤2:连接器

Now for this whole build,I had used three PVC connector.

  • 90度角
  • PVC end Cap
  • 聚氯乙烯台式丝杠

The Corner was painted,用喷漆漆成黑色

The PVC Table Screwand End Cap was actually 3D printed as I was not getting in the local market so I designed my own in Fusion 360.

你可以从课堂上学到很多关于设计的知识。金宝博娱乐城

Step 3: Fix the Connector

Now it was time to fix the table mount connector to the melamine board.So I drilled some holes using a 3 mm Drill bit.
I used my Black and Decker Drill Cordless drill for that.然后使用3 1/4英寸的螺钉将底座固定到三聚氰胺上。

Step 4: Assemble the Pipes

现在是时候组装它们了。I first fixe the 12 " pipe and 4" pipe using the corner Connector.
然后,我将12“管道的一端连接到桌子支架上。The other end of 4 " Pipe will be connected to end cap.

Step 5: Preparing the End Cap

Now it was time to prepare the end cap,the end cap will be holding the spring which will stretch the nichrome wire.既然端盖没有孔,I didn't design that rather took my drill to make a hole.I mounted an eye hook then to end cap and fixed it with a nut .

Step 6: Adding the Ni-chrome Wire

Now it was time to add the main thing,the NiChrome wire.I had got this Nichrome wire by salvaging it from Hair drier.The Wire was then mounted with a spring to the eye hook.金属丝被拉伸以保持金属丝的张力,这样切割时就不会变形。

步骤7:准备电线

Now it was time to add power to wire so that it can cut like butter.我用一个12V 5 A适配器给系统充电,为了连接系统,我所做的就是将导线焊接到鳄鱼夹上,然后在需要使用时将鳄鱼夹连接到导线上。
该系统的另一个优点是,通过改变夹子的位置,电阻变化,因此电流,所以最高温度也会变化。This helps when dealing with thin foam sheet.

Step 8: Adding Rubber Feet

Lastly,I added some rubber feet so that this won't scratch the table when used on it.你可以跳过这一步,if you want but this makes the station more usable on the table and also it won't slide here and there when used to cut foam.

Step 9: Enjoy Foam Cutting

那么它能切割的材料是什么呢??
泡沫切割机可切割

  1. 2-inch Foam sheet
  2. 10“堕落”
  3. 泡沫板
  4. Foam Block

Not sure if you've been informed,但是“下载”链接并没有真正起作用(可能只有我一个人),我只得到第一页的一个扩展版本。我想这可能是个教科书问题吧?

He clearly stated a 12 V 5 amp supply.You could use something like a notebook power supply or probably the best bet is a variable voltage bench power supply.我们买了一个高达30伏和10安培约70美元的阳极氧化铝。You can get 5 amp supplies for a lot less.使用120V会很危险,因为如果你穿过电线的两端,你会被吸引到120伏。

Foam board as in Foamcore?我会说你可能引起火灾,and the wire might break.我从未见过有人尝试切割泡沫芯或鳄鱼板,但是一张聚苯乙烯泡沫塑料,对,quite easily.

Good question.在电影业,美国专业雕刻家(雕刻家联合当地755)我们使用的是一台变阻器电压控制机。它们很贵,但值得付出代价,because you can control voltage from very,非常,low to very,非常,高。Here is a link to a site that carries these machines.

Very nice build.I want to chime in as I had been a sculptor who has worked on some really huge Hollywood feature film productions sculpting massive sculptures for feature films as well as sculpting huge movie sets like rockwork for movies such as Pirates of the Caribbean for Disney and Planet of the Apes (Tim Burton's film) and many other films and television shows.

我想对使用聚苯乙烯泡沫塑料的任何人说什么(A.K.A.EPS泡沫),特别是如果您使用热线或热工具,even heat guns,to cut and shape it,you absolutely MUST wear the highest quality respirator with extra charcoal filters,otherwise,you could end up like me,发现你的身体过度,血液和脂肪组织中甚至含有大量的苯乙烯。在使用这种化学泡沫时,我确实戴了相当高质量的口罩。And yet,this chemical is highly pervasive and apparently finds other ways to enter the body besides the lungs.Always suit up and wear a disposable protective suit and cover your head/hair and wear disposable gloves when working with Styrofoam (EPS foam).

Keep in mind that all of these foams in their many forms are all made from the processing of the base source which is from crude oil.Crude oil is a highly toxic substance that can be and is refined into literally thousands of other highly toxic,cancer-causing chemicals which are very poisonous.Take EVERY precaution when working with what we have all been led to believe are just wonderful,simple-to-use,使我们的生活更轻松、更愉快的日常材料。

如果你只做两个或三个项目的泡沫,then it's probably not a problem,但是如果你像我一样每天都用它,then take every precaution.Have fun DIYing!

Do NOT heat cut foam in a closed environment.确保通风量很高。
