Embodiment Construction

[0029] figure 1 A schematic diagram of a rolling stand 1 is shown. The rolling stand 1 includes a rolling stand 5 , a pair of back-up rolls 2 and a pair of work rolls 3 for processing a metal piece G. Furthermore, the rolling stand 1 is comprised of figure 1 The abutment system not shown in detail.

[0030] If a metal part G enters the rolling stand 1 , springback of the rolling stand 1 and thus a change in the set roll gap between the work rolls 3 occurs.

[0031] In order to compensate for this springback or unwelcome changes in the roll gap between the work rolls 3, the figure 1 In the embodiment of the present invention, two measuring devices 6 are provided, which detect the deformation of the rolling stand 5 of the rolling stand 1 by means of a distance measurement. in press figure 1 In the exemplary embodiment these measuring devices are configured as Temposonic displacement sensors.

[0032] For the distance measurement by means of the measuring device 6 , a refer...

Abstract

The invention relates to a method for producing a metal product (G) by means of a roll stand (1) and / or edger, to a device for determining spring-back of a roll stand (1) and / or edger, and to a method for determining spring-back of a roll stand (1) and / or edger while metal products (G) are being worked. As a result of at least two reference points (R1, R2, R3, R4) for determining the spring-back being predetermined, at least one of the reference points (R1, R2, R3, R4) being on a stand unit (5), in particular a stand frame (5), that deforms while the metal product (G) is being worked, and of a relative position of the at least two reference points (R1, R2, R3, R4) with respect to each other while the metal product (G) is being worked being determined, and spring-back of the roll stand (1) and / or edger being ascertained therefrom, a method for directly determining the spring-back can be provided, which is considerably more precise than the existing indirect method.

Description

technical field [0001] The invention relates to a method for ascertaining the springback of a rolling stand and / or a rolling stand during the machining of a metal part and a method for manufacturing by means of a rolling stand and / or a rolling stand method of metal parts. Furthermore, the invention relates to a device for ascertaining the springback of a rolling stand and / or a vertical rolling stand. Background technique [0002] The present invention is within the technical field of rolling mill technology. Rolling mill technology investigates the manufacture of metal products by means of a rolling process which can be carried out in the form of cold or hot deformation. [0003] For the rolling process used, conventional rolling methods can be used, in which the work rolls for processing the rolling stock are arranged horizontally. Said horizontal rolling method is generally used to adjust a specific thickness of a metal part. As a result, the mechanical properties of t...
