Embodiment Construction

[0013] Such as Figure 1-Figure 5 As shown, the main components of the implementation mechanism of the vertical roll height adjustment method include a fixed frame 1, a roll seat 2, a fixed block 3, an adjustment screw 4, a lower wedge 5, an upper wedge 6, a rear adjustment nut 7, and a front adjustment nut. 8. Coupling block 9, jacking bolt 10, lock nut 11 and internal thread sleeve 12.

[0014] The lower wedge-shaped block 5 is placed on the fixed frame 1, the lower plane of the lower wedge-shaped block 5 is fitted with the upper plane of the fixed frame 1, and the upper surface of the lower wedge-shaped block 5 is an inclined plane. The upper wedge block 6 is installed under the roll seat 2 height limit plates, the upper plane of the upper wedge block 6 is fitted with the lower plane of the limit plate, and the lower surface of the upper wedge block 6 is an inclined plane. The slopes of the lower wedge block 5 and the upper wedge block 6 fit together, and when their relati...

Abstract

Disclosed is a vertical roller height adjustment method and implementation mechanism. A lower wedge block is placed on a fixing frame; a roller base height limiting plate is arranged on an upper wedge block; the inclined surfaces of the two wedge blocks are attached to each other; when the relative front and back position is changed, the distance between the lower surface of the roller base height limiting plate and the upper surface of the fixing frame can be changed so as to implement the adjustment on the height of a main roller; a fixing block is arranged behind the lower wedge block, a screw penetrates a through hole of the fixing block, the front end of the screw is connected with the lower wedge block, a front adjustment nut and a rear adjustment nut are arranged on the screw, and the two adjustment screws can be loosened or tightened to push and pull the lower wedge block to move forward or backward through the screw; the roller base height limiting plate is provided with an internal thread sleeve, a jacking bolt is arranged in the internal thread sleeve and used for jacking a roller base, and accordingly the front and back position of the lower wedge block is convenient to adjust. According to the vertical roller height adjustment method and implementation mechanism, the convenient and rapid adjustment on the height of the main roller can be implemented and accordingly the accurate requirements of the special cross-section ring part rolling process for the hole pattern height of the main roller are met.

Description

technical field [0001] The patent of the present invention relates to a roll adjustment method and implementing mechanism, especially a vertical roll height adjusting method and implementing mechanism. Background technique [0002] At present, the height of the vertical rolls of general rolling mills is not adjustable, and the rolls with fixed heights are no problem for the roll forming of rectangular cross-section parts. However, for the roll forming of special-shaped cross-section parts, it is often necessary to adjust the height of the vertical roll to meet the precise height position requirements of the roll pass, so the height of the vertical roll must be continuously adjustable conveniently and quickly. Contents of the invention [0003] In order to meet the precise and continuous adjustment of vertical roll pass height for rolling forming of special-shaped cross-section parts, the patent of the present invention creates a vertical roll height adjustment method and i...
