Abstract
The invention discloses a high-strength bolt, and relates to a part fastening technology. A joint part of a bottom plane of a head of the bolt and a rod part is made into inward concave circular arc connection; a joint washer is provided with an upward convex circular ring; and the upward convex circular ring can be just jointed in a circular arc groove of the bottom plane of the head of the bolt. During manufacturing, metal fibers cannot be cut off, so that the safety performance of the bolt can be obviously improved.
Description
Technical field
The present invention relates to a kind of fastenings technology, concrete is a kind of high-strength bolt.
Background technique
High-strength bolt generally is used between the higher link of some security requirements; Existing high tenacity generally all is to select for use the high-quality steel as raw material by bolt on making, and blank adopts the method for forging to process, and existing high-strength bolt is in the process of blank forging; All be that vertical structural type is processed with bar portion in the bottom plane of the head of bolt; Because this structural type, bolt blank are in the process of making, the steel fiber of the junction of bolt shank and bolt head bottom is cut off easily; That causes bolt not only reduces the Safety performance of bolt easily, even brings serious potential safety hazard.
Summary of the invention
The objective of the invention is to: be directed against existing high-strength bolt because the bottom plane of the head of bolt is vertical structural type with bar portion; Steel fiber is cut off easily in the process of making; Cause the Safety performance that not only reduces bolt easily of bolt; Even bringing the defective of serious potential safety hazard, the present invention provides a kind of novel high-strength bolt, overcomes the existing existing above-mentioned shortcoming of high-strength bolt.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: this a kind of high-strength bolt comprises bolt, agrees with packing ring, the annulus boss; It is characterized in that: the bottom plane of the head of described bolt is processed the circular arc that caves inward with the connecting part of bar portion and is connected; The described packing ring that agrees with has the annulus that raises up, and this annulus that raises up can agree with just in the arc groove of the bottom plane of the head of bolt.
Beneficial effect: the present invention is owing to process the circular arc that caves inward with the bottom plane of the head of bolt with the connecting part of bar portion and is connected, so steel fiber can not be cut off in the process of manufacturing, and the Safety performance of raising bolt.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present invention.
Shown in the figure: 1. bolt, 2. agree with packing ring, 3. annulus boss.
Embodiment
In the drawings; This a kind of high-strength bolt comprises bolt 1, agrees with packing ring 2, annulus boss 3; The blank of described bolt 1 adopts the method for forging to process; In the process of forging, the circular arc that caves inward is processed with the connecting part of bar portion in the bottom plane of the head of bolt is connected, agree with the methods of packing ring 2 same employing forgings and process; Have the annulus boss 3 that raises up agreeing with to process on the packing ring 2, the annulus boss 3 that this raises up can agree with just in the arc groove of the bottom plane of the head of bolt 1.
