Numberall manufactures an economical range of 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-Operated (Model 136), Air-Operated (Model 136A) and Motorized (Model 137) versions.
The Model 136 is hand-operated. By manually pulling the lever, a cam is rotated to create the stamping force. The table would be adjusted so that when the cam rotates to high cam position, minimal effort is required to mark the part.
The Model 136A uses an air-cylinder to generate its power. A hand-operated lever valve is pulled toward the operator. This causes the ram to move down to stamp the part. Once stamped the lever valve is released, the ram then moves to the home position. The Model 136A is a very simple, low maintenance press with very few moving parts. In fact, we do not recommend any spare parts for this machine!
The Model 136A can also be adjusted so that any part thickness within the stroke range can be stamped without height adjustment. By simply adjusting the air pressure, the press will stamp to a certain depth. Essentially the press will “stall out”, but will not damage the part or press components because the air pressure is lower than standard.
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. The Model 136A can be equipped with an optional two-hand trip. Numberall’s 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.
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.
A variety of marking devices can be installed in the presses, depending on part thickness and character capacity requirements.
