Description
Technical Field
The utility model belongs to the field of rolling mill auxiliary equipment, and particularly relates to a guide locking device.
Background
The guide and guard device is a device which is arranged in front of and behind the roll pass in the process of rolling the section steel and helps the rolled piece to enter and exit the roll pass accurately and stably according to the set direction and state, and is used as important auxiliary equipment of a rolling mill, and the clamping effect of the guide and guard device on the rolled piece directly determines the quality of the rolled piece. The rolling guide can drive the worm wheel and the guide roller shaft part to adjust the opening degree of the guide roller, namely the distance between the two guide rollers, so as to ensure that the guide rollers have good clamping effects on rolled pieces of different specifications. Therefore, after the opening degree of the rolling guide is adjusted, the worm bolt is fixed through the anti-rotation clamp, so that the worm bolt is prevented from rotating in the rolling process, and the clamping effect of the guide on the rolled piece is affected.
At present, two types of rolling guide locking devices are mainly used at home and abroad, one type is a U-shaped semi-open type anti-rotation clamp which is mainly suitable for locking small-specification rolled piece guides, deformation resistance is overlarge in the rolling process of large-specification rolled pieces, impact force can deform the large-specification rolled pieces to lose locking effect, and the anti-rotation clamp positioned at the lower part of the rolling guide locking device can lose locking effect because the rolling guide is used on a vertical rolling mill and the rolling guide is separated from a bolt to be locked due to gravity; the other is a totally-enclosed anti-rotation clamp which solves the problem of guide and guard locking of a large-size rolled piece, but the problem that the lower anti-rotation clamp is separated from a bolt to be locked due to gravity is not solved. Moreover, when the rolling guide is used in a side groove of a rolling mill, the anti-rotation clamp can be blocked by the rolling mill frame and can not be opened due to overlong, so that an adjuster can not adjust the opening degree of the guide on line, and can only take off the guide from the rolling mill again for readjustment, thereby greatly influencing the production efficiency.
