Abstract
Abstract A pressure transmitting means is disposed between the pressure rod and the slide or ram member of a forging press. The pressure transmitting means has over its entire width in the lower zone thereof facing in a direction toward the slide member, a diameter different from another diameter in the upper zone which faces in a direction toward the pressure rod. The diameters are offset with respect to each other on one side of the transmitting means and are in contact with each other on the other side of the transmitting means. The pressure rod is connected to the pressure transmitting means which is a pin member in a specific embodiment so that forces acting eccentrically on the slide or rod member can be rectilinearly transmitted to the eccentric crankshaft of the forging press by the slide or ram member and the pressure rod.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
146 words
In a forging press having a driven crankshaft including an eccentric portion, a pressure rod, a slide or ram member which carries the forging tool, an adjustment mechanism for varying the stroke position of the slide member with respect to the platen and means for arresting said adjustment mechanism, the combination comprising: a. a pressure transmitting means disposed between the pressure rod and the slide member, b. said pressure transmitting means having, in the lower zone facing in a direction toward the slide member, a first diameter different from another diameter in the upper zone facing in a direction toward the pressure rod, c. said diameters being offset with respect to each other on one side of the transmitting means and being in contact with each other on the other side of said means, and d. means for connecting the transmitting means to the pressure rod.
Claim 2
Dependent Claim
146 words
In a forging press having a driven crankshaft including an eccentric portion, a pressure rod, a slide or ram member which carries the forging tool, an adjustment mechanism for varying the stroke position of the slide member with respect to the platen and means for arresting said adjustment mechanism, the combination comprising: a. a pressure transmitting means disposed between the pressure rod and the slide member, b. said pressure transmitting means having, in the lower zone facing in a direction toward the slide member, a first diameter different from another diameter in the upper zone facing in a direction toward the pressure rod, c. said diameters being offset with respect to each other on one side of the transmitting means and being in contact with each other on the other side of said means, and d. means for connecting the transmitting means to the pressure rod.
Claim 3
Dependent Claim
40 words
In a forging press as defined in claim 1 wherein said pressure transmitting means includes a pin member having pin studs disposed at each end thereof and the first diameter extending over its entire width in the lower zone thereof.
Claim 4
Dependent Claim
39 words
In a forging press as defined in claim 2 wherein said connecting means includes projections which engage the pin studs, said projections being disposed on the pressure rod which extends in length over the entire width of the pin.
Claim 5
Dependent Claim
39 words
In a forging press as defined in claim 2 wherein the aDjusting mechanism is mounted on the slide member and acts on the lower zone of the pressure transmitting pin for rotating said pin about its axis of rotation.
Claim 6
Dependent Claim
33 words
In a forging press as defined in claim 1 wherein said arresting means includes balancing cylinders and a clamping bow adapted to be tensioned on the pressure transmitting means by the balancing cylinders.
Claim 7
Dependent Claim
28 words
In a forging press as defined in claim 1 wherein said arresting means includes a clamping bow arranged in the central transverse plane of the pressure transmitting means.
Claim 8
Dependent Claim
35 words
In a forging press as defined in claim 1 wherein said arresting device includes a clamping bow and means for effecting the movement of the clamping bow between a clamping position and an unclamped position.
Claim 9
Dependent Claim
42 words
In a forging press as defined in claim 1 wherein said arresting means includes a means for clamping the pressure transmitting means into a fixed clamping position and means for moving the clamping means between a clamping position and an unclamped position.
Claim 10
Dependent Claim
16 words
In a forging press as defined in claim 8 wherein said moving means includes balancing cylinders.
Claim 11
Dependent Claim
41 words
A device as defined in claim 8 wherein said clamping means is pivotally movable around a pivot point located on the slide member and said moving means includes balancing cylinders for effectuating movement of the clamping means around its pivot point.
Claim 12
Dependent Claim
70 words
In a forging press as defined in claim 8 wherein said clamping means includes a pivotally mounted clamping bow having a cantilever arm connected to one side thereof, said arresting means includes a bell crank lever acting on the other side of the clamping bow so that a force on either the bell crank lever or the cantilever arm will tend to pivot the clamping bow about its pivot point.
Claim 13
Dependent Claim
40 words
In a forging press as defined in claim 11 wherein said moving means includes balancing cylinders and a means for connecting a first cylinder to operate the bell crank lever and a second cylinder to act on the cantilever arm.
