Problems solved by technology

The straightening of long workpieces lying flat on roller tables therefore also has precision limits, since the elastic recovery of long workpieces after each bending step is hindered by friction between workpiece and roller table

Embodiment Construction

[0020] as in figure 1 Clearly visible in , the straightening machine marked as a whole with 100 comprises a press frame 1 movable horizontally along guide rails 4, 4A, 4B, said press frame having straightening heads 1A acting vertically and spacing Variable vertically acting straightening anvils 1B, 1C. Like the press frame 1 , the two clamping devices 2A, 2B are motor-driven longitudinally displaceable along the guide rails 4 , 4B of the machine bed 5 . Alternatively, it can be provided that the press frame 1 is fixedly arranged, which is not shown in the figures.

[0021] The clamping devices 2A and 2B together with the straightening head 1A and the straightening anvils 1B and 1C define a machining path WP shown in dotted lines, which coincides with the workpiece W clamped for machining ( Figure 3A -C). Accordingly, the working area delimited by the straightening head 1A and the straightening anvils 1B, 1C is a subpath of the working path WP. Due to the movability of th...

Abstract

The invention relates to a device for feeding long workpieces (W) into and removing same from a processing machine, such as a bending-straightening machine, in which the long workpiece (W) located in the processing positions defines a processing section (WP) and the long workpiece (W) is supported at both end regions thereof by a respective gripping arrangement (2A, 2B). In straight extension (EPA, EPB) of the processing section (WP), a horizontal conveying means (3) for the long workpiece (W) adjoins at least one head end (WPA, WPB) of the processing section (WP). At least one of the gripping arrangements (2A, 2B) has a gripper head (8A, 8B) for frictionally gripping an end (WA, WB) of the workpiece (W) conveyed by the horizontal conveying means and drive means for drawing the workpiece (W) to be straightened into the processing section (WP) and for pushing out the straightened workpiece onto the at least one horizontal conveying means by means of the gripper head.

Description

technical field [0001] The invention relates to a straightening machine having the features of the preamble of claim 1 as well as to an input and output device according to claim 2 and a pairing of long workpieces according to claim 15 therefor. method of straightening. Straightening machines for long workpieces are therefore equipped with two clamping devices of variable height and spacing that define the machining path. The two clamping devices support the long workpiece in an approximately horizontal position at least between the straightening steps in different tool positions, in particular at the workpiece ends, and enable a rotational drive about the workpiece axis in order to be able to move the long workpiece The straightening process is realized in different rotational angle positions. The straightening machine has at least two straightening anvils arranged between the clamping devices in the longitudinal direction of the workpiece and spaced from each other as seen...
