Numberall manufactures a variety of economical bench-top presses. Bench-top mounting saves valuable floor space and keeps larger presses free for other work. The bench-top presses are available in hand power (Model 136), air power (Model 136A) and motorized (Model 137) versions. These presses are compact and easily mounted on a workbench. They are designed for quickly marking name plates and other flat objects.

Description

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 effective through many years of service. Its operation is simple. The operator moves the operating lever down and the press cycles. With the standard Single Stroke Control, the press will only cycle once until the lever is released and actuated again. Motorized operation reduces operator’s fatigue.

An acme screw and nut below the cast table regulate depth of stamping. A separate guiding 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. Numberall’s standard dovetail shank allows quick changing of marking devices. The same dovetail is used in all of our 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 have 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 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.

 

Maximum Part Thickness Chart
Depicts the maximum allowable part thickness, based on the marking device and character size. The total clearance under the ram is 3-3/4”, but can be modified for additional opening; contact the factory for availability.
Marking Device Maximum
Opening
Model 23P (up to 5/32” character) 1-5/8”
Model 23P (3/16” to 1/4”character) 1-1/4”
Model 70P (up to 1/8” character) 1-9/16”
Model 70P (3/16” to 1/4” character) 1”
Model 50P (up to 1/8” characters) 1-9/16”
Model 50P (5/32” and 3/16” character) 1/2”
Note: For the Maximum Part Thickness Chart, any Numbering Machine or Type Holder not listed cannot be used in the above presses.
Character Capacity Chart
Depicts the maximum number of characters that can be stamped during each impression. These recommendations can be exceeded in many cases. The hardness of a material will affect stamping results.
