Abstract
The utility model belongs to the improvement of steel rolling heavy and medium plate mill guide and guard bolt arrangement, particularly a kind of medium plate mill guide and guard bolt of improvement, comprise finishing mill guide apparatus stud bolt, the bolt end face that guide and guard stud bolt is positioned at roller side arranges cross recess, in cross recess, be fixedly mounted with positioning key, the bolt end of the guide and guard stud bolt the other end arranges cubic boss.Its intensity is high, connects safe and reliable, indeformable, and can reduce the maintenance amount of equipment, the working life of extension device, the generation of minimizing accident, enhances productivity.
Description
Technical field
The utility model belongs to the medium plate mill guide and guard bolt of the improvement of steel rolling heavy and medium plate mill guide and guard bolt arrangement, particularly a kind of improvement.
Background technique
The existing guide and guard bolt of steel rolling heavy and medium plate mill due to roller side do not locate, material 45 heat treatment HB217-255, intensity is lower, above composite factor is bolt looseness or elongation usually, cause guide and guard and upper guide plate loaded area to reduce, cause guide and guard to rush to summit accident, also can cause aggravating the wearing and tearing of copper lining board, cause the waste in spare part and man-hour, also cause maintenance amount to increase, shorten the time of production, reduce manufacturing efficiency.
Model utility content
The purpose of this utility model is the medium plate mill guide and guard bolt providing a kind of improvement, and its intensity is high, connects safe and reliable, indeformable, and can reduce the maintenance amount of equipment, the working life of extension device, the generation of minimizing accident, enhances productivity.
The purpose of this utility model is achieved in that a kind of medium plate mill guide and guard bolt of improvement, comprise finishing mill guide apparatus stud bolt, the bolt end face that guide and guard stud bolt is positioned at roller side arranges cross recess, in cross recess, be fixedly mounted with positioning key, the bolt end of the guide and guard stud bolt the other end arranges cubic boss.
Guide and guard bolt is arranged cross inside groove in roller side by the utility model, is convenient to location.In cross inside groove, install positioning key, welding location, placing nut loosens.Make bolt material into forging 42CrMo by 45# steel HB217-255 and modulate HB250-280, improve machining accuracy, gain in strength, avoid screw rod to elongate plastic deformation.Inner screw nut is made into 10.9 grades of high-strength nonstandard hexagon slotted nuts.When bolt is installed, coat drier oil, prevent from getting rusty.Change two sides of construction bolt card spanner into 4 sides, and size is increased to improve intensity, be convenient to dismounting.The stress concentration point of former design bolt has been carried out angle setting, and dispersive stress is concentrated with anti-fracture.
The good effect that the utility model produces:
Guide and guard bolt strength of the present utility model is high, connects fastening security, and bolt no longer loosens, elongation, add the life-span of guide and guard slide plate and copper lining board, decrease upkeep operation amount, decrease guide and guard and to rush to summit the generation of accident, add the production time, decrease maintenance cost.
It is high that the utility model achieves intensity, connects safe and reliable, indeformable, decreases the amount of maintenance of equipment, extends the working life of equipment, decreases the generation of accident, improve manufacturing efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of medium plate mill guide and guard bolt of improvement, as shown in Figure 1, comprise finishing mill guide apparatus stud bolt 1, the bolt end face that guide and guard stud bolt 1 is positioned at roller side arranges cross recess, in cross recess, be fixedly mounted with positioning key 2, the bolt end of guide and guard stud bolt 1 the other end arranged cubic boss 3.Guide and guard stud bolt 1 is made up of 42CrMo steel, and its quenching and tempering hardness is HB250-280.
