Problems solved by technology

Although solid steel columns can be dispensed with by using and guiding tensioning cables, the on-site assembly of the press frame is relatively labor-intensive, since the tensioning cables have to be guided through the entire press frame
This is rather difficult in large presses with correspondingly large-sized tensioning cables

Embodiment Construction

[0116] exist figure 1 The press 1 shown in has generally known press frame 2 structure by prior art, and it mainly comprises cylinder beam 3 and countertop beam 4, and the bracket mechanism 5 that is made up of four individual pressure struts 6 (in shown here as an example only). A respective tie rod 7 made of steel is arranged inside each pressure strut 6 . Each tie rod 7 protrudes not only from the cylinder beam 3 but also from the counter beam 4 on the outside, so that the respective ends 8 and 9 of the tie rods 7 can be screwed with a lock nut 10 or 11 (shown as an example here). ). The pressure struts 6 space the cylinder beam 3 and the bearing crosshead 4 from one another, while the press frame 2 as a whole is prestressed by means of tie rods 7 . This is achieved by tightening the two union nuts 10 and 11 of the respective tie rods 7 , whereby the component parts cylinder beam 3 , support crosshead 4 and pressure strut 6 are pressed against one another and at the same...

Abstract

The device (20) has a tie rod (21) comprising two anchor bodies (22, 23) arranged at a machine frame, and a traction element (24) for receiving tensile force between the anchor bodies, where the traction element is stretchable along a tension line (25) of the tie rod (21). One of the anchor bodies (22,23) is provided with a reversing device (26) for reversing the direction of the traction element (24).

Description

technical field [0001] The invention relates to a device for rack pretensioning, having a tensioning column, which includes first and second column heads for being placed on the frame, and a tensioning element for bearing the tension between the column heads , wherein the tensioning element extends along the tensioning distance of the tensioning column. [0002] The invention also relates to a machine frame with upper and lower crossheads for absorbing the machining forces introduced into the machine frame, with machine elements for spacing the crossheads from one another and with at least one crosshead extending between the crossheads. An active tensioning strut, wherein the tensioning strut has a tensioning element and two studs at the ends of the tensioning element, and wherein the tensioning strut is supported by means of the struts on the crosshead. [0003] The invention also relates to a pressing or tensioning device with a frame and a device for pretensioning the fram...
