Hydraulic power units

  • Model 700-SV-1A
  • This power unit offers 1-1/2 horsepower for operation of presses requiring greater portability than afforded with some of the larger model power units. It weighs only 65 pounds and operates at 5000 psi on 115 volt, 60 hz single phase
  • Model 700-5V-3A, 700-5V-10A and 700-SV-20A
  • These power units use a pump, reservoir and valving assembly sized for either 3, 10 or 20 horsepower electric motors. This line of power units is available in single (1V), double (2V), and three valve (3V) models and operate also at 5000 psi

Bridge strippers

  • If a hole to be punched is near the edge of the part and both legs of the standard adjustable ring stripper cannot contact the material, it is necessary to use a bridge stripper. This stripper should also be used for thin materials that could become deformed by the stripping force. It can be easily attached to the bottom of a ring stripper with set screw

Die Clearance (ASTM-A36 Structural Steel)

  • Be sure to allow for proper die clearance. The standard clearance of the die styles used with our presses and die diameter should be approximately 15% of the material thickness. Consult factory for recommended die clearances for other materials
MATERIAL THICKNESS DIE CLEARANCE
(in.) (in.)
1/8 thru 1/4 .020 over nominal (.020)

Pin location (790XX, 7502, 7602 keyed dies)

  • When ordering shaped dies, specify LR (left to right) or FB (front to back) placement. If not specified, LR location will be shipped

Handlebars

  • Are available on many models, for convenience in positioning presses

* Interchangeable within obtainable size range – but limited to a maximum of 100 tons punching force. #770 punches can only be used for punching round holes. For shaped holes use of keyed alignment feature is recommended. Presses with keyed feature are available at additional cost.

Suspension springs

  • Suspension springs allow the operator to easily and quickly “float” the press when locating the hole to be punched. These springs are available in different sizes. The spring capacity is determined by the weight of the press to be suspended. A spring may be fastened to an overhead crane, or other movable support, to obtain greater portability of the press
