Many newoutstanding features are prominent in this equipment, such as, 80,000 pound tensile strength holders, 4140 alloysteel guides, oil hardening tool steel punches and dies. The units can be furnished for either round or shaped holepunching. The “C” frame holders are keyed for shaped hole punching at no extra cost. The base of the holders areprovided with a pilot pin hole machined on the center line of the punch and die bore for quick and accurate templatelocation. A second pilot pin location is machined 11/2" behind the front pilot hole. The purpose of the second pilot pinlocation is to prevent the holders from pivoting when shaped punches and dies are used in the units.MODEL HMODEL HHPAGES 3-11PAGES 18-22MODEL HMODEL HHThis popular unit will serve most applications.

HEAVY DUTYfeed thrupunching unitsround and shaped holesMAXIMUM MATERIAL THICKNESS – 1/4" MILD STEEL(UP TO 1/2" MILD STEEL FOR MODEL HFT-3½)Unittool’s Heavy Duty Feed Thru Punching Units are recommended for perforating operations where it is desirableto feed the material through from thefront or back of the press. This systemcan also be used to punch holes fromthe edge of the material that are beyondthe reach of “C” frame tooling.There is no throat depth to be considered with this style of equipment. Theassembly can be set up outside of thepress, therefore saving valuable presstime. The complete bed rail and unitassembly can be placed in the press,ready to operate, in just a few minutes.All punch holders and die holders arekeyed for shaped hole punches and dies.The punches, dies, guides, springs, etc.used in this equipment are the sameparts used in Unittool’s Heavy Duty “C”Frame Units. This can represent considerable savings when converting fromone style unit to another.22U n i t to ol p u n c h & Di e
Feed Thru Hole Punching UnitsFigure 1This method requires a locatingtemplate to matchthe hole pattern of thepart to be punched. Thelocating template is placedin the 47/8" wide recess of theBed Rail. Bolting or securingthe locating template to the BedRail is not required.The template material is .500thick cold rolled steel. Any widthtemplate from 1" to 43/4" may beused to suit the hole pattern requirements. The purpose of the47/8" wide template space is forretaining the Bed Rail Spacers asshown in Figure 2. (See page 1of Mounting Accessories and Engineering Data Catalog.)Figure 2Illustration to show Bed Rail with Bed RailSpacer that can be used instead of a template.Spacer can be adjusted along the rail to suit aparticular hole pattern.The locating template is producedby drilling and reaming a .375diameter pilot pin hole for eachround hole location. Pilot pin is onthe center line of each Die Holder.For shaped hole locations – drilland ream for two .375 diameterpilot pin on 1.500" centers.Figure 3Illustration to show how Upper Bed Rail Assembly can be used with a tee slotted plate.(Ask for quotation.)Figure 4Copyright Unittool Punch & Die CompanyLitho in USA23
