At invention disclosed patent on the 5th CN 101134206A March in 2008, introduced a kind of combined memorial archway (frame), whole memorial archway is decomposed the combined memorial archway that is designed to be convenient to dismounting, processing and transportation.But because its design feature, need to adopt 8 bolts to connect column and crossbeam, and its column is a solid construction, must be unfavorable for reducing the weight of memorial archway (frame), the manufacturing cost of reduction memorial archway (frame) and the stiffness coefficient of increase memorial archway (frame) like this.
The utility model content
Technical problem to be solved in the utility model provides the prestressing force rolling mill frame of the light and low cost of manufacture of a kind of stiffness coefficient height, weight.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of prestressing force rolling mill frame, comprise entablature, sill and two root posts, described two root posts vertically are installed on the left and right sides between entablature and the sill, and be fastenedly connected by the prestressing force double-screw bolt respectively, two prestressing force double-screw bolts pass the axially extending bore on two columns respectively; In conjunction with after entablature, sill and two root posts between form a closed rectangular window.
As preferably, the junction of described column and entablature and sill is provided with the circular orientation cover.
As preferably, described column is welded by multistage, and the junction of per two sections columns is provided with the circular orientation cover.
As preferably, the middle part diameter of axially extending bore is greater than the two ends diameter of axially extending bore on the described column.
The utility model prestressing force rolling mill frame, by the prestressing force double-screw bolt two root posts vertically are assemblied in the left and right sides between entablature and the sill, also be the stressed member of frame when making the prestressing force double-screw bolt as connector, bear whole pretightning forces, as long as its pretightning force greater than the tensile force in the operation of rolling, just can guarantee the rigidity and the whole frame reliability of double-screw bolt; In addition, the tensile force that column here bears when not being rolling, but when rolling opposite pretightning force, therefore the function harsh requirement of collateral security milling train rigidity of column, change on this function of the relative position degree of accuracy that guarantees roller system, just because of this, the weight of column can alleviate greatly, and gross weight can reduce about about 40%.
The utility model prestressing force rolling mill frame is provided with the circular orientation cover in the junction of column and entablature and sill, in order to the installation site of accurate location prestressing force double-screw bolt, to guarantee the dimensional accuracy of framework window; Column can be designed to be welded by multistage, and the junction of per two sections columns is provided with the circular orientation cover, can make its casting more convenient like this; The middle part diameter of axially extending bore is designed to the two ends diameter greater than axially extending bore on the column, and column is from the solid hollow of making, and raw material can save 45%, is the low-carbon type structure.
In sum, the utility model prestressing force rolling mill frame, adopt split type prestressing force syndeton, effectively reduce the manufacture difficulty and the processing cost of frame, improved its stiffness coefficient simultaneously, guaranteed reliability and machining accuracy when rolling mill is rolling, also reduce the weight of frame in addition greatly, having saved material consumption and energy consumption, met low-carbon type structure Design theory, is a kind of more optimal combined rack.
