PORTABLE METAL SAWING MACHINES

The portable metal sawing machines described in this section are those lightweight and easily transportable saws that are used in a field or normal machine shop by maintenance personnel. These saws can be used to cut stock that is too big or too long to move to a maintenance shop to be cut. The following portable sawing machines are described in this section: the portable hacksawing machine, the portable band sawing machine, and the portable reciprocating saw. Two of these saws are operated by hand, so the quality of work depends upon the experience and skill of the operator. Portable metal sawing machines can be used in the maintenance shop to cut wood, steel, plastics, electrical conduit, tubing, pipes, and shop stock, and for auto body work.

THE PORTABLE HACKSAWING MACHINE

The portable hacksawing machine (Figure 1) is not designed to be hand-held, but to lock onto the workpiece with a self-contained vise. This saw has a built-in electric motor that causes a power hacksaw blade to reciprocate at a fixed speed of 115 strokes per minute. The machine is capable of cutting solid steel 3 inches square and at an angle to 45°. This saw can be used in a horizontal, angular, or vertical position, having an adjustable counterbalance to compensate for operating the sawing machine in a vertical position. A 10-inch power hacksaw blade is used with this machine, producing a 4-inch stroke. A tension screw permits increasing or decreasing the blade pressure with each cut. The portable hacksawing machine will support itself when fastened very securely to a stationary workpiece, using the self-contained vise.

 

To operate the portable hacksawing machine, insert a power hacksaw blade of 18, 24, or 32 teeth per inch, depending on the material to be cut. Then, check the adjustment of the tension screw and the adjustment of the counterbalance lever. Turning the tension screw clockwise will increase the amount of lift the hacksaw blade makes on each return stroke and will increase the downward pressure of the blade on each cutting stroke. Counterclockwise rotation of the screw will decrease the lift and pressure. This control should be adjusted to cause the hacksaw blade to lift 1/8 inch on each return stroke to provide maximum cutting speed and efficiency. The counter balance lever controls the downward pressure exerted upon the hacksaw blade by the weight of the saw frame. By moving the counterbalance lever to the left, the pressure is decreased. Moving the lever to the right increases the pressure. Mount the workpiece squarely or angularly in the vise, depending on the type of cut desired. Start the sawing machine and observe the cutting action. If the machine strains, the blade pressure may be too heavy.

If the machine cuts very slowly, increase the pressure.

Continuously check the power hacksaw blade for sharpness. If the blade is dull, it should be replaced. When the machine cuts completely through the material, the saw frame will fall and trip the motor switch, stopping the saw.

When the sawing machine is used in the vertical position, the counterbalance lever must be positioned in the farthest right notch of the guide bar ratchet to compensate for the lack of gravitational pressure normally applied to the blade by the saw frame. This practice should be attempted only if the workpiece can be clamped very securely in the vise and cannot be wrenched loose during vertical sawing, or damage to personnel or equipment could occur.

SIERRAS DE METAL PORTÁTILES

Las sierras de metal portátiles descritas en esta sección son aquellas sierras de poco peso y fácilmente transportables que son utilizadas en campo o un taller de máquinas o de uso normal por el personal de mantenimiento. Estas sierras se pueden utilizar para cortar material que es demasiado grande o demasiado largo moverse al taller de mantenimiento para su corte. Las sierras portátiles siguientes se describen en esta sección: la sierra alternativa portátil para metal, la sierra portátil de cinta, y la sierra recíproca portátil. Dos de estas sierras se operan a mano, así que la calidad del trabajo depende de la experiencia y la habilidad del operador. Las sierras de metal portátiles se pueden utilizar en el taller de mantenimiento para cortar madera, acero, plásticos, conductos eléctricos, tuberías, cañerías, mercancía en almacén, y para trabajos de carrocerías de automóviles.

LA SIERRA CORTAMETALES PORTÁTIL

La sierra para metales portátil (figura 1) no está diseñada para ser operada a mano, sino para ser fijada sobre el objeto de trabajo con un tornillo de banco adjunto. Esta sierra viene con un motor eléctrico incorporado que hace que una resistente lámina de sierra para metales se mueva en forma alternativa a una velocidad fija de 115 movimientos por minuto. La máquina es capaz de cortar acero sólido de 3 pulgadas cuadradas y en ángulos de 45°. Esta sierra puede ser utilizada en una posición horizontal, angular, o vertical, teniendo un contrapeso ajustable para compensar el funcionamiento de la sierra en una posición vertical. Una lámina de sierra eléctrica para metales de 10 pulgadas se utiliza con esta máquina, produciendo un movimiento de 4 pulgadas. Un tornillo de tensión permite aumentar o disminuir la presión de la lámina con cada corte. Esta máquina de corte portátil se soportará a sí misma cuando está sujeta en forma segura a un objeto de trabajo inmóvil, usando el tornillo de banco o morsa adjunto.

Para hacer funcionar la máquina portátil de corte de metales, inserte una hoja de sierra de máquina para metales de 18, 24, o 32 dientes por pulgada, dependiendo del material que se cortará. Luego, compruebe el ajuste del tornillo de tensión y el ajuste de la palanca de contrapeso. Al girar el tornillo de tensión en sentido horario aumentará la cantidad de elevación que la hoja la sierra para metales hace en cada movimiento de vuelta y aumentará la presión hacia abajo de la hoja en cada movimiento de corte. La rotación en sentido anti horario del tornillo disminuirá la elevación y la presión. Este control se debe ajustar para hacer que la hoja de la sierra para metales se levante 1/8 pulgada en cada movimiento de vuelta para proporcionar velocidad y eficacia máximas de corte. La palanca de contrapeso controla la presión de bajada ejercida sobre la hoja de sierra para metales por el peso del bastidor de sierra. Moviendo la palanca de contrapeso a la izquierda, se disminuye la presión. Al mover la palanca a la derecha, se aumenta la presión. Coloque el objeto en ángulo recto o angular en el tornillo de morsa, dependiendo del tipo de corte deseado. Encienda la sierra y observe el movimiento de cizallamiento. Si la máquina trabaja forzada, la presión de la hoja puede ser demasiado pesada.

Si la máquina corta muy lentamente, aumenta la presión.

Compruebe continuamente el filo de la hoja de sierra para metales. Si la hoja está gastada, debe ser substituida. Cuando la máquina finaliza el corte de todo el material, el marco de sierra caerá y disparará el interruptor del motor, parando la sierra.

Cuando la máquina de aserrar se utiliza en posición vertical, la palanca de contrapeso se debe colocar en la muesca a la derecha más alejada del trinquete de la barra de guía para compensar la falta de presión gravitacional aplicada normalmente a la hoja por el marco de sierra. Esta práctica debe ser intentada solamente si el objeto se puede fijar mediante abrazadera con mucha seguridad en la morsa y que no se pueda aflojar durante el aserrado vertical, o podría producir un daño al personal o al equipo.

THE PORTABLE BAND SAWING MACHINE

The portable band sawing machine (Figure 2) or portable band saw is a lightweight, hand-held unit powered by an electric motor. The saw motor and gears rotate a solid steel band saw blade around two large wheel pulleys and through several saw blade guides at such an angle to give clearance to the workpiece being cut. The portable band saw can cut steel round stock to 3 3/8 inch diameter or steel rectangular stock 3 3/8-inch thick by 4 1/8 inch wide. The portable metal band sawing blades are 44 7/8 inches long and can have from 6 to 24 teeth per inch, providing a wide range of cutting capabilities. Single-speed band saw models are designed for softer metals, such as brass, aluminum, and mild steel. Two-speed and variable speed models can be switched to a low speed to cut harder metals, such as stainless steel or tungsten. The band saw blade is completely enclosed, using the motor housing as a blade guard, except for the exposed part of the blade that does the sawing. A hand grip and trigger switch are provided on one end of the saw and a knob grip is on the other end to provide for maximum control while sawing.

To start sawing, make sure that the material to be cut is held very securely in the vise to avoid excessive vibration.

Select the appropriate blade for the material to be cut and mount the blade securely into the portable band saw in accordance with the manufacturer's instructions. Take hold of the front knob grip handle and rear hand grip handle and squeeze the trigger switch to start the saw blade in motion. Set the speed appropriately if operating a two-speed or variable speed model. Gently lower the portable band saw onto the workpiece, being careful to use the weight of the machine as pressure to cut. If the operator uses additional pressure on the workpiece, the saw blade will slow down and reduce the cutting efficiency. Hold the machine steady and the saw blade straight to avoid twisting or breaking the blade. At the completion of the cut, do not allow the saw to fall onto the workpiece. Maintain hand control of the machine, release the trigger switch, and allow the blade to stop before setting down the saw. Never use a liquid coolant with the portable band sawing machine as this could damage the saw guide bearings or rubber pulleys. Lubricate and service each saw as specified in the manufacturer's instructions.

THE PORTABLE RECIPROCATING SAW

The portable reciprocating saw (Figure 3) is a handheld lightweight machine tool that can be electrically or pneumatically powered, depending on the model selected. The saw motor and gearing cause a single knife-like blade to move rapidly in and out, sawing across a workpiece as hand pressure is applied. The saw may be a one-speed model or two speed model. The one-speed model operates at high speed only and is used for cutting soft materials like wood or sheet rock. The two-speed models have a switch that can move the speed from high speed to low speed, so that harder materials, such as metal pipes and steel sheets, can be cut.

The portable reciprocating saw, with the proper blade installed, can cut through steel stock up to 1 inch square or steel pipe up to 4 inches in diameter. An enclosed hand grip handle with trigger switch is provided at one end of the saw and another hand grip is toward the front of the saw, near the blade, to provide for maximum control while sawing. The blade freely protrudes from an angled work rest that is attached to the motor housing. There is no blade guard, so care must be exercised at all times.

 

LA MÁQUINA ASERRADORA DE CINTA PORTÁTIL

La máquina de sierra de cinta (figura 2) o máquina aserradora de cinta portátil es una unidad liviana, manual accionada por un motor eléctrico. El motor y los engranajes de la sierra hacen girar una hoja de sierra de cinta sólida de acero alrededor de dos poleas ruedas grandes y a través de varias guías de hoja de sierra a un ángulo tal que permita el espacio necesario al objeto que es cortado. La máquina aserradora de cinta portátil puede cortar material redondo de acero de hasta de 3 3/8 pulgada de diámetro o material rectangular de acero 3 3/8 pulgadas de espesor por 4 1/8 pulgada de ancho. Las hojas de sierra de metal de la máquina portátil tienen 44 7/8 pulgadas de largo y pueden tener desde 6 hasta 24 dientes por pulgada, proporcionando una amplia gama de capacidades de corte. Los modelos de máquinas de aserrar de velocidad única están diseñados para metales más blandos, tales como latón, aluminio, y acero blando. Los modelos de dos velocidades y de velocidad variable se pueden cambiar a baja velocidad para cortar metales más duros, tales como acero inoxidable o tungsteno. La hoja de sierra de banda está totalmente oculta, usando el compartimento del motor como protector de hoja, a excepción de la parte expuesta de la hoja que realiza el corte. Una manivela y un interruptor de encendido se encuentran en un extremo de la sierra y una perilla de agarre se encuentra en el otro extremo para proporcionar máximo control mientras se asierra.

Para comenzar a aserrar, cerciórese de que el material que se cortará está ajustado muy firmemente en la morsa para evitar una vibración excesiva.

Seleccione la hoja apropiada para el material que será cortado y coloque la hoja con seguridad en la sierra portátil de banda de acuerdo con las instrucciones del fabricante. Tome la perilla de sujeción frontal y la manija posterior y presione el interruptor disparador para poner la hoja de sierra en movimiento. Fije la velocidad apropiadamente si opera un modelo de dos velocidades o de velocidad variable. Baje suavemente la sierra portátil de banda sobre el objeto, teniendo cuidado de utilizar el peso de la máquina como presión para cortar. Si el operador utiliza presión adicional sobre el objeto, la hoja de sierra se volverá más lenta y se reducirá la eficacia del corte. Sostenga la máquina firmemente y la hoja de sierra en forma recta para evitar torcer o romper la hoja. Al finalizar el corte, no permita que la sierra caiga sobre el objeto. Mantenga el control manual de la máquina, libere el interruptor de disparo, y permita que la hoja se detenga antes de apagar la sierra. Nunca utilice un líquido refrigerante con la sierra portátil de banda pues esto podría dañar los rodamientos de guía de la sierra o las poleas de goma. Lubrique y mantenga cada sierra según lo especificado en las instrucciones del fabricante.

LA SIERRA RECÍPROCA PORTÁTIL

La sierra recíproca portátil (también conocida como sierra sable, sierra reciprocante, sierra de movimiento alternativo, sierra caladora, sierra alternativa , etc.) (Figura 3) es una máquina herramienta liviana manual que se puede accionar eléctrica o neumáticamente, dependiendo del modelo seleccionado. El motor y el engranaje de la sierra hacen que una sola lámina similar a un cuchillo se mueva rápidamente hacia adentro y fuera, aserrando a través de un objeto mientras que la presión manual es aplicada. La sierra puede ser un modelo de velocidad única o un modelo de dos velocidades. El modelo de velocidad única funciona a alta velocidad solamente y se utiliza para cortar materiales blandos como madera o planchas de roca. Los modelos de dos velocidades tienen un interruptor que pueden cambiar la velocidad desde velocidad alta a baja velocidad, de modo que materiales más duros, tales como tubos de metal y hojas de acero, puedan ser cortados.

La sierra recíproca portátil, con la hoja apropiada instalada, puede cortar a través material de acero de hasta 1 pulgada cuadrada o caños de acero de hasta 4 pulgadas de diámetro. Una manija con el interruptor de disparo incluido se encuentra en un extremo de la sierra y otra manija para sujeción está hacia la parte frontal de la sierra, cerca de la hoja, para proporcionar control máximo mientras se asierra. La lámina resalta libremente de un portapiezas anguloso que se fija al compartimento del motor. No hay protector de lámina, así que se debe tener cuidado siempre.
