Embodiment Construction

[0017] Roller group installation: Put the roller group 3 on the roller changing trolley 2, the roll changing hydraulic cylinder 1 works, push the roller group 3 into the U-shaped frame 7, turn the swivel 8 and the connecting bolt 9 and the U-shaped frame 7 to form a concave The groove rotates the locking mechanism 6 to fix the roll group 3 together (the effect of the turning ear prevents the roll system from jumping during the rolling process and ensures that the rolling line is fixed). Roller group replacement: Unscrew the connecting bolt 9, turn the swivel 8 to disengage from the U-shaped frame 7, and use the hydraulic cylinder to push out the roller group. The roller group and the U-shaped frame are locked on the column through the hydraulic cylinder (such as Figure 7 shown in 4).

Abstract

The disclosed no frame vertical short stress path rolling mill belongs to metallurgical equipment field. The mill comprises roll changing hydrocylinder (1), with rolling mill group (3), roll changer (2), post (4), worm wheel lifting gear (5), U-shaped frame (7), rotation ear (8) and bolt (9). The hydrocylinder runs to pull mill group into U-shaped frame, wherein, the groove rotation locking mechanism (6) composed of rotation ear, bolt, and U-shaped frame fixes the mill group on post with a couple of screw threads, on which the bolt realizes symmetric adjust. This invention cancels frame of mill self and big frame to fix whole mill, which realizes simply structure, light weight, convenience to operate and change, low cost and symmetric adjust.

Description

Technical field: [0001] The invention belongs to the field of metallurgical equipment, in particular to a vertical rolling mill. Background technique: [0002] Most of the existing vertical rolling mills are large and small frame type, the small frame is fixed on a large frame, the frame weight is heavy, the machining is difficult, the processing volume is large, and the cost is high. Vertical rolling mill. Not only that, because the frame rolling mill rolls are assembled in a closed frame (small frame), when changing the roll group (the working mechanism of the rolling mill), it must be extracted from the frame side window. In addition, the adjustment of the roll gap of the frame vertical rolling mill is to fix one roll and adjust the other roll. During the frequent adjustment of the roll gap opening of the rolling mill (in order to adapt to the change in the size of the rolled steel piece) and after changing the roll, The rolling line (i.e. the bisector of the centerline...
