Model 137 Bench Top Press, Price Quote Only
Operation
The Model 137 is a motorized press. It requires 120 volts AC electricity, so it can be used anywhere there is an outlet. It utilizes a 1/4 horsepower electric motor to drive a worm gear reducer. The clutch and cam mechanism is a design that has been proven in many years of service. Its operation is simple: the operator moves the operating lever down, the press cycles. With the optional Single Stroke Control the press will only cycle once until the lever is released and actuated again. Without the Single Stroke Control, the press will continually cycle until the lever is released.
An acme screw and nut, attached below the cast table, regulate depth of stamping. A separate guide rod helps align the table. By turning the acme nut you can raise or lower the table for depth adjustment.
The presses feature a short safe 3/16” stroke, negating the need for external guarding. Our standard dovetail shank allows quick changing of marking devices. The same dovetail is used in all of Numberall’s presses as well as the Model 116 Dovetail Adapter.
Construction & Parts
The Models 136, 136A and 137 use the same base casting. Numberall's presses are husky, cast iron "C" frames for distortion-free stamping with a smooth, static non-impact marking force. No die cast parts are used. Many imported presses are made using round column construction with a spring release marking force, which may result in a harsh impact shock. The large quick-change dovetail ram evenly distributes the marking force across the marking device frame, with minimal part and marking device stress. Clearances and pressures are the same for each model.
Compatibility
A variety of marking devices can be installed in the presses, depending on part thickness and character capacity requirements.
