Guiding and guarding clamping device and rolling machine

Abstract

The invention provides a guiding and guarding clamping device and a rolling machine. The guiding and guarding clamping device comprises a framework, an adjusting mechanism comprising two screws and a guiding and guarding mechanism comprising an upper guiding and guarding box and a lower guiding and guarding box, wherein the framework comprises an upper cross beam and a lower cross beam which are opposite, a first side wall and a second side wall which are opposite, a first front pressing plate and a first rear pressing plate which are vertically connected to the first side wall, and a second front pressing plate and a second rear pressing plate which are vertically connected to the second side wall; a first sliding groove is defined by the first side wall, the first front pressing plate and the first rear pressing plate, and a second sliding groove is defined by the second side wall, the second front pressing plate and the second rear pressing plate; first and second external threads are separately arranged at the upper and lower parts of each screw; the two ends of the upper guiding and guarding box are separately arranged in a manner capable of sliding in the first sliding groove and the second sliding groove and are in surface contact with the first sliding groove and the second sliding groove; the two ends of the lower guiding and guarding box are separately arranged in a manner capable of sliding in the first sliding groove and the second sliding groove and are in surface contact with the first sliding groove and the second sliding groove; and the screws rotate and drive the upper and lower guiding and guarding boxes to slide in a face-to-face manner or back-to-back manner. The guiding and guarding clamping device has large bearing capability.

Description

Technical field [0001] The invention relates to the technical field of steel rolling machinery, in particular to a guide and guard clamping device and a rolling mill. Background technique [0002] In the prior art, taking flat steel as an example, the phenomenon of squaring is prone to occur during rolling. The squaring refers to that the cross section and sharp corners of the flat steel, especially the special flat steel, are not vertical during rolling. At present, most of the guide and guard devices used in the production line are conventional guide and guard modes, which can only assist in the introduction of rolled parts, and do not have a large carrying capacity. [0003] At the same time, because flat steel, especially special flat steel, is produced in small batches and multiple varieties, the existing guide and guard device cannot realize online real-time adjustment. If the production requires a change of variety, the corresponding guide and guard device needs to be repla...
