Problems solved by technology

The disadvantage of this method is that the main frame needs to be turned over many times on the machine tool, which is very difficult and time-consuming for such a heavy part; and by measuring the thickness of the main frame everywhere, the indirect control of the main frame deflection is also necessary. Unreliable, very likely to produce errors, affecting the accuracy of the main frame

Embodiment Construction

[0020] In order to effectively eliminate the deflection of the main frame due to its own weight and control the influence of the deformation of the main frame on the accuracy of the rolling mill, the present invention adopts the following method to control the deflection and deformation of the main frame due to its own weight.

[0021] 1. Deflection control of the main frame in the rough state

[0022] See figure 2 As shown, the main frame has a rectangular shape, with ears 2 extending symmetrically at both ends of one side. After the marking platform is cleaned, draw a cross line according to the center of the length and width of the marking platform, and draw a rectangular line with the center of the cross line as the center. Place the main frame within the rectangular line on the marking platform, and place the main frame in the middle of the rectangular line (the purpose of this is to make the main frame roughly aligned when it is placed). With the inner side of the main fram...

Abstract

The invention discloses a method for eliminating deflection in the process of processing a main rack of a rolling mill, which comprises the following steps of: arranging a jack between lower end faces of end parts of two lugs of the main rack, respectively arranging dial gauges between the upper end angles of the two lugs of the main rack and the right side end of the main rack, and regulating the dial gauges to position '0'; lifting the main rack upwards with the jack until gaps appear between the lower end faces of the two lugs of the main rack and two sizing blocks under the two lugs; respectively measuring the gaps between the two sizing blocks and the lower end faces of the two lugs of the main rack, adjusting the difference between the two gaps by a spacer with a thickness of a halfof the gap difference, and then loosening the jack; and adding a spacer with the same thickness on the sizing block on the lower end face of the main rack on the same side after the sizing block is added with the spacer. The method can effectively control the deflection deformation generated in the process of processing the main rack of the rolling mill.

Description

Technical field [0001] The invention relates to a processing method of a main frame of a rolling mill, in particular to an in-rolling mill. The method of controlling the deformation of the frame by eliminating the deflection in the manufacturing process of the main frame. Background technique [0002] The main frame in the horizontal rolling equipment is the most important part of the entire rolling production line. In order to ensure the manufacturing precision of the equipment, there are strict precision requirements for the machining of parts of the main frame. [0003] The single-piece weight of the main frame of the rolling mill is 50 to 400 tons. Due to the limitation of machining equipment, the main frame can only be fixed horizontally and then processed, and then the main frame is erected during assembly. For such heavy and large parts, a certain amount of deflection and deformation will be produced by the gravity of the horizontal processing. If the deflection cannot be ...
