Abstract
A kind of short ending cylindrical die roll, is characterized in that：Including cylindrical die roll body, cylindrical die roll guide portion and ridge head guide portion are provided with cylindrical die roll body, cylindrical die roll guide portion on cylindrical die roll body is provided with chamfering, and each ridge head guide portion is provided with a lozenges relative to end slope on cylindrical die roll body；Using the technical scheme, the flighted length of bolt after processing shortens under same intensity rating conditions, alleviate bolt weight itself, the height of the Closely locking nut supporting with screw-thread ending length after processing also reduces, therefore installed weight significantly reduces, and compared with plain bolt, averagely mitigates weight 13%, cylindrical die roll service life extends, and processing cost per unit reduces.
Description
Technical field
The present invention relates to aircraft fastening device technical field, specifically a kind of short ending cylindrical die roll.
Background technology
Existing large aircraft, every frame reach up to a million using fastener, so, mitigating the weight of body turns into research side
To one of, but in the prior art, by bolt loss of weight come realize to the effect of the overall loss of weight of aircraft have it is to be hoisted.
Existing common alloy of titanium bolt cylindrical die roll physical dimension is larger, because titanium alloy bolt all uses rolling in processing
Silk wheel is processed, and leader chamfering is excessive in thread rolling die design structure of the prior art, in ridge start-up portion meeting
It is very weak, have a strong impact on cylindrical die roll service life.The product quantity that every width cylindrical die roll can be processed is less, is only capable of processing 2.4
Ten thousand products, cylindrical die roll purchase cost is higher, and the cylindrical die roll cost for sharing single-piece titanium alloy fastener is also higher.
The content of the invention
The purpose of the present invention, exactly solve problem present in above technology, and a kind of short ending cylindrical die roll is provided for this.
A kind of short ending cylindrical die roll, including cylindrical die roll body, cylindrical die roll guide portion and screw thread are provided with cylindrical die roll body
Tooth head guide portion, the cylindrical die roll guide portion on cylindrical die roll body are provided with chamfering, and each ridge head draws on cylindrical die roll body
The portion of leading is provided with a lozenges relative to end slope.
Further, the chamfering is identical with thread form angle.
Further, the chamfering is 50 ° -65 °.
Further, the chamfering is 60 °.
Further, the match specifications of length and ridge of the inclined-plane of lozenges along cylindrical die roll circumferencial direction.
Further, the lozenges is relative to 45 ° of cylindrical die roll end slope.
Further, threadingly tooth form bearing of trend angle of inclination is identical with guide angle for the lozenges.
Further, the lozenges does not involve second complete thread.
Advantages of the present invention：
1, the flighted length of the bolt after processing shortens under same intensity rating conditions, alleviates bolt weight itself；
2, the height of the Closely locking nut supporting with screw-thread ending length after processing also reduces, therefore installed weight significantly drops
It is low, compared with plain bolt, averagely mitigate weight 13%；
3, cylindrical die roll service life extends, and processing cost per unit reduces.
