Abstract
The invention discloses a strength knockout pin which comprises a body, a bolt is welded at one end of the body, a fixed nut is welded at the other end of the body, the strength knockout pin also comprises a screw and a movable nut, the screw is matched with the fixed nut, and the movable nut is matched with the screw. The strength knockout pin disclosed by the invention has the beneficial effects that the application of a steel pipe body ensures that the strength knockout pin has enough strength, so that the strength knockout pin is not bent and deformed when the strength knockout pin is pressed against honorific arches on both sides of the strength knockout pin; and the strength knockout pin disclosed by the invention has the advantages of simple structure, good application effect, simple and easiness for operation.
Description
Technical field
The present invention relates to metallurgical technical field of steel rolling, especially relate to a kind of powerful push rod that can hold out against the mill housing slide plate.
Background technology
As everyone knows, the size of mill housing slide plate and working roll bearing block slide clearance is determining mill milling stability.If the excesssive gap between two kinds of slide plates, the important tool of steel rolling---roll will swing back and forth, rolled piece is at reciprocal whipping between different directions thereupon when rolling, not only cause template control difficulty, to all exerting an adverse impact in the impact of mill housing, the stable service life that reaches machine working roller balance cylinder of spindle etc., therefore window size is most important between accurate measurement mill housing slide plate simultaneously.Take bolt to cooperate between mill housing and slide plate, in the production process of fast pace high load capacity, under the long duration of action of external force, getting loose may appear in connecting bolt, the gap appears between mill housing and slide plate, first fastening bolt before measurement size, then measure, according to measurement size configuration bearing block slide plate size, but according to said process mill housing slide plate with after the working roll bearing block slide plate cooperates, in the two actual moving process or because rocking appears in excesssive gap, influence of rolled is stable.Observe through long-time afterwards, find the mill housing bolt hole through after the elasticity bolt repeatedly, bolt hole increases, and is connected with bolt closely to connect, and causes the measurement size distortion, can't closely cooperate thereby cause between mill housing slide plate and working roll bearing block slide plate.Therefore, need a kind of mill housing slide plate of development to hold out against equipment, eliminate the gap between mill housing and slide plate, accurately measure the memorial archway window size, be of a size of benchmark reasonable disposition bearing block slide plate size with this, satisfy production requirement.
Summary of the invention
The object of the invention is to overcome the shortcoming that exists in the prior art, a kind of powerful push rod is provided, the authenticity of measuring to improve window size, this push rod can improve the simplicity of execute-in-place operation greatly, and provide reliable reference for configuration roll chock slide plate size, the technical scheme that adopts is: a kind of powerful push rod, comprise body, it is characterized in that: an end of described body is welded with bolt, the other end of body is welded with hold-down nut, and described powerful push rod also comprises the screw rod that cooperates with described hold-down nut and the traveling nut that cooperates with described screw rod.
Technical characterictic of the present invention also has: described body is that external diameter is that Φ 40mm, length are the steel pipe of 1400mm.
Technical characterictic of the present invention also has: the large footpath of described bolt thread is 36mm.
Beneficial effect of the present invention is: the use of steel pipe body has guaranteed that this powerful push rod has enough intensity, and self is not crooked, indeformable when holding out against the both sides memorial archway, and that the present invention has is simple in structure, result of use good, the advantage of easy easy operating.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention, and wherein 1 is body, the 2nd, and bolt, the 3rd, hold-down nut, the 4th, screw rod, the 5th, traveling nut, the 6th, weld zone.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.The invention discloses a kind of powerful push rod, comprise body 1, be welded with bolt 2 at an end of body 1, the other end of body 1 is welded with hold-down nut 3, and powerful push rod also comprises the screw rod 4 that cooperates with hold-down nut 3 and the traveling nut 5 that cooperates with screw rod 4.
In the present embodiment, body 1 is that Φ 40mm, length are one section steel pipe of 1400mm for external diameter, and material is No. 45 steel.The length that bolt 2 stretches out body 1 is 120mm, and bolt 2 is the bolt of M36.
During use, the end of bolt 2 is contacted with a side memorial archway slide plate, the end of screw rod 4 by rotating traveling nut 5, is satisfied the needs of Space adjustment between the memorial archway slide plate towards opposite side memorial archway slide plate.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also belong to protection scope of the present invention.
Claims (3)
1. a powerful push rod comprises body, it is characterized in that: an end of described body is welded with bolt, and the other end of body is welded with hold-down nut, and described powerful push rod also comprises the screw rod that cooperates with described hold-down nut and the traveling nut that cooperates with described screw rod.
2. according to powerful push rod claimed in claim 1, it is characterized in that: described body is that external diameter is that Φ 40mm, length are the steel pipe of 1400mm.
