Device for adjusting the stroke on eccentric presses

The innovation relates to a device for adjusting of the stroke on eccentric presses with one on the drive * ζ ent he stored EX2enterbuoh.se, especially on eolohen ίτββββη, whose ram drive is completely installed * a »B, in an oil bath runs, and therefore not jzrugänglioa iat.

In known eccentric presses, the stroke must be adjusted the drive parts accessible, it must be ζ · Β. a ver * schjaraubung be loosened, a ring twisted, a connection be solved or the like «* The adjustment of the stroke is usually cumbersome and time-consuming, especially with heavy eats and those with two angles, for their & Λ adjustment a special drive must be installed the machines are considerably expensive »

The hiring consists in the fact that the eccentric and the eccentric bush by means of holding means that can be operated on the outside of the machine are rotatable and adjustable against each other, whereby in the drive of one of the during operation with the same rotation

number of revolving eccentric files, a release clutch is built in and a retaining device that can be disengaged is attached in the uncoupled position to prevent rotation.

With the nice door direction, the stroke can be easily adjusted even on presses with a built-in * inaccessible drive. The door direction can be used for light and heavy seizures, for presses with one or two fieuels.

If one of the eccentric ropes, for example, is disengaged and held against rotation, the eccentric bush can be calibrated of the eccentric, for example, by a short engagement and disengagement of the drive coupling relative to the eccentric bushing · twist Then, the eccentric bushing is re-engaged, so that the ropes in a new Winkeleteilung are held to each other, in which the oils remain during further operation * The new position provides a different slide stroke »

In one design, the release clutch is installed between a gate shaft that drives the eccentric and the eccentric bushing together and the eccentric bushing »

Torteilhaft the coupling is one of a fixed and existing a sliding sleeve, expediently on the chance of scoring countershaft itself arranged dog clutch · To actuate the clutch, a control member is provided for coupling in further innovation outside the machine, such as an actuator for a hydraulic or pneumatic Yentil a corresponding drive «

One of the other features of the hiring is that it has a display device for the wheel of the stroke adjustment is expediently attached to the outside of the press, whereby the angle adjustment of eccentric and eccentric bushing against each other as hatred for the stroke adjustment.

The operator can see to what extent or for how long he has to engage the drive coupling in order to classify a broken boy »
