COMO FABRICAR UNA PRENSA O TORNILLO DE BANCO

¿QUÉ ES UN TORNILLO DE BANCO?

El tornillo de banco es una herramienta de gran utilidad en el taller, tanto para uso doméstico (bricolaje) como para uso profesional.

El tornillo es el complemento ideal del banco de trabajo (por eso se llama de banco). Con el podrás mecanizar todo tipo de piezas con seguridad y precisión.}

¿Para qué sirve un tornillo de banco?

Gracias a un tornillo de banco puedes hacer operaciones complejas, como taladrar en una tubería u otra superficie curva, de manera efectiva y reduciendo el riesgo de accidentes.

Algunos de los elementos que se pueden sujetar en un tornillo son:

  • Clavos, varillas roscadas o tornillos: para cortarlos con una sierra de metal
  • Pletinas gruesas de chapa o fundición: para taladrarlas o roscarlas
  • Varillas de ferralla: para doblarlas
  • Brocas, cinceles, punteros, cuchillos y otras herramientas: para afilarlas

Partes de un tornillo de banco

Las partes de un tornillo de banco

Un tornillo de banco está formado por las siguientes partes:

  • Dos mandíbulas: también llamadas mordazas. Son las que oprimen la pieza sujetada.
  • Base perforada: permite atornillar el tornillo al banco de trabajo.
  • Guía: sirve para el desplazamiento de la parté móvil del tornillo en la cual está montada la mandíbula móvil.
  • Palanca: atraviesa el husillo roscado. Con ella se hace rotar el husillo roscado.
  • Husillo roscado: es el que permite abrir y cerrar el tornillo.
  • Yunque: sirve para golpear piezas sobre él.

Características y principio de funcionamiento de un tornillo de banco

Estructuralmente, un tornillo de banco está formado por una pesada bancada sobre la que se ubican dos mordazas, una fija y otra móvil. La mordaza móvil se aleja o se acerca de la fija mediante un husillo giratorio roscado accionado mediante una palanca.

Mordazas de un tornillo de banco: lisa y estriada (moleteada)

El husillo, también conocido como tornillo de potencia o tornillo de traslación, está tallado sobre un redondo de acero de gran diámetro con rosca cuadrada. El husillo es el responsable de convertir el movimiento circular de la palanca en el desplazamiento rectilíneo de la mordaza móvil.

Además de la palanca principal, este útil puede incluir otros órganos de ajuste que nos permiten rotar la base del tornillo para conseguir una mejor postura de trabajo sobre la pieza.

Tipos de tornillos de banco

Según el material con el que están hechos, podemos hablar de dos tipos de tornillos:

  • Tornillos de banco de fundición son los más baratos pero son frágiles y no soportan esfuerzos elevados torsión ni golpes fuertes.
  • Tornillos de acero forjado: son los tornillos profesionales que se usan en talleres de reparación e industrias
