The utility model discloses an accurate guide device for hot
continuous rolling of a
kovar alloy plate. The accurate guide device comprises a rack, a conveying roller, a guide mechanism, a fixing mechanism and a cleaning mechanism, the rack is fixed on the ground; the conveying rollers are evenly and rotationally connected to the
machine frame through bearings, and the guiding mechanisms are symmetrically installed on the two sides of the
kovar alloy plate. The fixing mechanism and the cleaning mechanism are both mounted on the guide mechanism; the guide mechanism comprises a support frame, a connecting plate, a rotating roller, a bidirectional
threaded rod, a guide rod and a motor II; the two-way
threaded rod is rotationally connected to the rack through a bearing, and the guide rods are fixed to the portions, on the two sides of the two-way
threaded rod, of the side wall of the rack. The motor is fixed to the outer side wall of the rack, and the output end is connected with one end of the bidirectional threaded rod. According to the utility model, the
Kovar alloy plate can be accurately guided; in the
Kovar alloy plate guiding process, the side wall makes contact with the rotating roller, friction can be reduced, and damage to the
Kovar alloy plate is further reduced.
