Copper shoe is installed in bearing both sides, and allows pincers worker in a pre-installation to copper shoe match grinding.Although at match grinding initial stage, copper shoe serves as a contrast with milling train
Sheet separation is smaller, and the precision of whole milling train is also relatively good, but changes several times after roll, and abrasion, gap change just occurs in copper shoe
Greatly, the precision of milling train is caused to reduce.Now just need to change copper shoe, allow pincers worker again to copper shoe match grinding.Match grinding belongs to pincers
Work industry, and labor strength is high, low production efficiency, and high to the horizontal degree of dependence of labour skill of worker, and this just needs
Increase the quantity of spare roll, add cost.
Utility model content
The purpose of this utility model is to provide a kind of rolling mill hydraulic pressure liner plate component, solves current rolling mill
The problem of bearing block copper shoe serious wear causes rolling mill precision to reduce.
The utility model is the technical scheme adopted is that a kind of rolling mill hydraulic pressure liner plate component, including liner plate body,
The center of liner plate body is provided with two pistons, and each piston exterior is coaxially socketed with pressure ring, four summits punishment of liner plate body
Not She You screw, disc spring is provided between the head of screw and pressure ring of screw.
The characteristics of the utility model, also resides in,
Wherein liner plate body is rectangular parallelepiped structure, and two circular grooves, two circular grooves edge linings are offered at the center of liner plate body
The length direction of plate body is set, and two pistons are accordingly arranged in two circular grooves.
The upper cover of piston rod of wherein piston is connected to piston packing.
Wherein pressure ring is arranged in circular groove with piston coaxial, and pressure ring is socketed in the outside of piston.
Wherein the contact position of the side wall of pressure ring and circular groove is provided with sealing ring A, and the bottom of pressure ring and the contact position of circular groove are provided with
Sealing ring B.
The beneficial effects of the utility model are a kind of rolling mill hydraulic pressure liner plate components disclosed in the utility model, will
Liner plate body is connected in rolling-mill housing, is acted by the piston rod of piston, and the compression reaction of disc spring, can effectively be adjusted
Gap on liner plate body and supporting roller bearing seat between copper shoe, when changing support roller, prevent copper on supporting roller bearing seat
Slide plate is worn, and solves the problems, such as that current rolling mill bearing block copper shoe serious wear causes rolling mill precision to reduce.
