A kind of guide and guard mounting bracket
Technical field
The utility model belongs to a kind of rolling equipment parts, specifically is a kind of guide and guard mounting bracket.
Background technology
Guide and guards is in the continuous section rolling system the accurate guiding of rolled piece to be entered roll pass and prevents the rolled piece surface by a kind of device of scratch, and its guiding accuracy is related to rolled piece quality and production safety.
Existing guide and guard mounting bracket is by installation frame, on the framework screw mandrel, slide block mechanism arranged, and band is installed on the slide block with the guide and guard of dovetail groove slide plate is installed.Because the guide and guard mounting bracket uses under rolling environment, cause screw mandrel very easily to get rusty, corrode, after normally the guide and guard mounting bracket uses a period of time, the screw mandrel corrosion, slide block can't move, slide plate can't be adjusted the position, lost the effect of slide block mechanism,, have to upgrade the guide and guard mounting bracket again for adapting to new guide and guard requirement, cause waste, also influence of rolled production.
The utility model content
The purpose of this utility model provides a kind of guide and guard mounting bracket, under the situation that does not change existing support, be covered with bellows or telescopic cover at screw mandrel, make screw mandrel not corroded by external environment, remain intact, conveniently carry out slide block and sledge displacement adjustment.
The technical solution of the utility model is as follows:
A kind of guide and guard mounting bracket, include framework, installing hole is arranged on the framework, on the underbeam of described framework screw mandrel is installed, on the described screw mandrel slide block is installed, the guide and guard that have dovetail groove are installed on the described underbeam slide plate is installed, described slide plate is fixedlyed connected with slide block, be slidingly matched between the silver bullion of inlaying on underbeam and slide plate or the slide plate, it is characterized in that described screw mandrel is with bellows or telescopic cover outward, scroll spring, described bellows or telescopic cover or scroll spring one end are fixedly connected on the slide block end, and the other end is fixedly installed in the screw mandrel end.
The screw mandrel at described slide block two ends all is with bellows or telescopic cover or scroll spring outward.
Compare with prior art, the utility model screw mandrel is subjected to the outer cover protection, is difficult for corrosion, and slide block and slide plate can conveniently be adjusted, and can adapt in the Rolling Production process, need often to adjust the needs of guide and guard position, provides cost savings, convenient again production.
