English term

apply tonnage

English to Polish Tech/Engineering Mechanics / Mech Engineering prasa krawędziowa - uchwyt stempla
Referring to the punch alignment procedure described in the operator’s manual of the machine, apply tonnage to each punch to secure it tightly against the holder.

These punches and dies are different in brittleness and allowable tonnage from the genuine punches and dies.

Securely fix the punches, dies, and die holders before applying tonnage to them

Before applying tonnage or starting the bending operation, check that all the levers are set at the position B and all the punches are securely fixed.

Pozdrawiam!

The 4 pillars of press brake tonnage limits Q: I have read many discussions on forming tonnages, yet it still makes no sense to me. I’ve heard about numerous variables—tool load, tonnage per foot, tonnage per inch, centerline limits, even “sink” tonnage. Which one is the right one for me to use? Should I be using more than one of these values?

Brake Press Terminology

Capacity / Tonnage – This is going to be the maximum force that the press brake can exert on the work piece.

przyłożyć obciążenie / obciążać

Tak jak apply a force to przyłożenie siły, to tutaj apply a tonnage to przyłożenie obciążenia lub po prostu obciążenie.

Przed obciążeniem w/w elementów należy je dobrze zamocować (z przyczyn oczywistych).

Hydraulic presses operate by means of two synchronized hydraulic cylinders on the C-frames moving the upper beam. Servo-electric brakes use a servo-motor to drive a ballscrew or belt drive to exert tonnage on the ram.

Pneumatic presses utilize air pressure to develop tonnage on the ram.

Until the 1950s, mechanical brakes dominated the world market. The advent of better hydraulics and computer controls have led to hydraulic machines being the most popular.

Pneumatic and servo-electric machines are typically used in lower tonnage applications. Hydraulic brakes produce accurate high quality products, are reliable, use little energy and are safer because, unlike flywheel-driven presses, the motion of the ram can be easily stopped at any time in response to a safety device, e.g. a light curtain or other presence sensing device.

Prasy krawędziowe spotykane są w wersjach hydraulicznych, elektrycznych, pneumatycznych a także mechanicznych.

Prasy hydrauliczne wykazują się największą siłą nacisku rzędu kilkudziesięciu czy kilkuset ton i wykorzystywane są do gięci grubych i długich blach, których długość to kilka metrów.

Prasy pneumatyczne czy elektryczne nie posiadają tak dużej siły nacisku często są jednak dużo szybsze od pras hydraulicznych i wykorzystywane są do wielkoseriowego gięcia małych elementów.

A brake can be described by basic parameters, such as the force or tonnage and the working length - https://en.wikipedia.org/wiki/Press_brake

The chart below illustrates the appropriate tonnages to air bend mild steel with 60,000 p.s.i. tensile properties.It must be noted that most North American steel mills are producing harder metals with typical mechanical properties of 44,000 p.s.i. yield and up to 80,000 p.s.i.tensile strengths. The tonnages required to form these metals are substantially higher and must be taken into consideration in the selection of a press brake - https://www.gladwinmachinery.com/sites/default/files/documen...
