Sheet metal cutting system

https://youtu.be/4YQudEBszzw

The system is used to make cuts in sheet metal, without deforming the cutting area, it is used for both steel and aluminum, with a thickness of less than 2 mm.

If you have access to an industrial shearing machine, the cuts are equally perfect, but in my case, since I do not have access to said machinery, I chose to build this simple cutting system, based on an angle grinder with a 12V lithium battery from the manufacturer Parkside ( model PWSA 12 Li A1).

Once all the parts are assembled, it allows to select the cutting height in a precise way, and also allows to slide it by a metal rule that serves as a guide to make the straight cut.

In my case the pieces I printed in ASA (110ºC hot bed and 260º hotend) since it supports higher temperatures (sparks of metal chips that come out of the metal cut) and mechanically is more resistant than the PLA.

I converted the hot bed of my Anet A8 into magnetic and as a printing surface I used metal sheets of 220 x 220 mm in both steel and aluminum, which I cut with this system.

The cutting system consists of 4 pieces:

Rail cut ** rail.stl **
It serves to slide the assembly longitudinally in contact with a guide rule (to make the straight cut), I use an extruded aluminum profile as a rule.

Spacer ** espacer.stl **
It serves to accurately set the cutting height. It is fastened to the rail with two M4 screws and wing nuts.

Shield anti shavings ** shield.stl **
It serves as a safety element to protect us from the projection of the hot metallic shavings resulting from the cut. It is attached to the spacer with two M4 self-locking nut screws.

Fastening housing ** fit.stl "
It serves to hold the grinder to the rail, requires three M4 screws and 2 normal nuts and one butterfly.


Sistema de Corte de Chapa

El sistema sirve para hacer cortes en chapa metálica, sin deformar la zona de corte, sirve tanto para acero o como para aluminio, con un espesor menor de 2 mm.

Si tienes acceso a una máquina de cizalla industrial los cortes salen igualmente perfectos, pero en mi caso al no tener acceso a dicha maquinaria, opte por construir este sencillo sistema de corte, basado en una amoladora angular a batería de litio 12V del fabricante Parkside (model PWSA 12 Li A1).

Una vez ensambladas todas las partes, permite seleccionar la altura de corte de forma precisa, y también permite deslizarlo por una regla metálica que sirva de guía para realizar el corte recto.

En mi caso las piezas la imprimí en ASA (110ºC cama caliente y 260º hotend) ya que soporta mayores temperaturas (chispas de virutas metálicas que salen del corte del metal) y mecánicamente es más resistente que el PLA.

Convertí la cama caliente de mi Anet A8 en magnética y como superficie de impresión utilizó chapas metálicas de 220 x 220 mm tanto de acero como de aluminio, que he cortado con este sistema.

El sistema de corte consta de 4 piezas:

Rail de corte rail.stl
Sirve para deslizar el conjunto longitudinalmente en contacto con una regla guía (para realizar el corte recto), yo utilizo un perfil de aluminio extruido como regla.

Espaciador espacer.stl
Sirve para graduar con precisión la altura de corte. Se sujeta al riel con dos tornillos M4 y tuercas de mariposa.

Escudo anti virutas shield.stl
Sirve como elemento de seguridad para protegernos de la proyección de las virutas metálicas calientes resultantes del corte. Se sujeta al espaciador con dos tornillos de tuerca autoblocante M4.

Carcasa de fijación **fit.stl”
Sirve para sujetar la amoladora al rail, requiere tres tornillos M4 y 2 tuercas normales y una de mariposa.
