Abstract
The utility model relates to a sectional bar for rolling rectangular torsional springs, in particular to a sectional bar for rolling rectangular torsional springs with large sections. The sectional bar has trapezoidal section and resolves the problem that rectangular torsional springs with trapezoidal sections are easy to be produced by means of rolling sectional bars with rectangular sections. Further, the section of the sectional bar is in the shape of an isosceles trapezoid, the height of the isosceles trapezoid is equal to that of the edge of the rectangular section formed via rolling, the length of the centerline is equal to the other edge of the rectangular section formed via rolling, and the proportion between the upper edge and the lower edge of the isosceles trapezoid ranges from 1:1.5-1:2. When the proportion between the upper edge and the lower edge of the isosceles trapezoid ranges from 1:1.8-1:8.5, the rectangular torsional springs formed via rolling have the best effect. The sectional bar with trapezoidal section is used for rolling to form torsional springs, and sections of the torsional springs are rectangular, thereby guaranteeing design requirements and preventing rectangular torsional springs with large sections from deforming.
Description
Technical field:
The utility model relates to a kind of section bar that rolls the rectangle torsion spring, particularly a kind of section bar that rolls large-section rectangle torsion spring.
Background technique:
At present, the rectangular cross-section torsion spring all adopts rectangle steel to roll, and for the less rectangle torsion spring in cross section, generally adopts cold coiling; And need adopt hot rolling for the large-section rectangle torsion spring that surpasses 12 * 12, as adopting the rectangular cross-section material, because outer surface is subjected to tensile stress, the internal surface compression chord can become trapezoidally when rolling when rolling, and can't guarantee rectangular shape, the size in cross section.
Summary of the invention:
The utility model has solved and has adopted the rectangular cross-section section bar to roll the problem that the trapezoid cross section appears in large-section rectangle torsion spring easily by a kind of section bar of trapezoid cross section is provided.
The utility model is achieved through the following technical solutions:
A kind of section bar that rolls rectangle large-section torsion spring, its cross section is an isosceles trapezoid, highly equal to roll the side of the rectangular cross-section of formation, midline length equals to roll the another side of the rectangular cross-section of formation, and the ratio of the top of isosceles trapezoid and bottom is between 1: 1.5～1: 2.
When the ratio of the last base of isosceles trapezoid and bottom is 1: 1.8～1: 85, roll rectangle Spring effect the best of formation.
The utility model adopts the material of trapezoid cross section to roll, and the cross section becomes rectangle after finishing, and can guarantee designing requirement, prevents large-section rectangle torsion spring section deformation.
Description of drawings:
Fig. 1 is a rectangle of the present utility model large-section torsion spring structural representation;
Fig. 2 is the utility model section bar sectional view.
Embodiment:
The section bar that rolls rectangle large-section torsion spring described in the utility model, its cross section are isosceles trapezoid, highly equal to roll the side of the rectangular cross-section of formation, and midline length equals to roll the another side of the rectangular cross-section of formation.The ratio of the top of isosceles trapezoid and bottom is between 1: 1.5～1: 2.
Embodiment 1:
Roll the spring sectional dimension 14 * 12 of formation, adopt isosceles trapezoid cross section section bar to roll, trapezoidal height is 12, midline length 14, and the ratio of last base and bottom is between 1: 1.5～1: 2, roll finish after, the side in rectangle spring cross section is 12, and all the other two edge lengths do not have slightly and wait, and minor face is 0.95～0.99 with the ratio on long limit, when the trapezoidal ratio of going up base and bottom was 1: 1.8, the ratio on minor face and long limit that rolls the rectangle spring cross section of formation was 0.99.
Embodiment 2:
The spring sectional dimension that rolls formation is 16 * 14 o'clock, adopt isosceles trapezoid cross section section bar to roll, trapezoidal height is 14, midline length 16, and the ratio of last base and bottom is between 1: 1.5～1: 2, roll finish after, the side in rectangle spring cross section is 14, and all the other two edge lengths do not have slightly and wait, and minor face is 0.95～0.99 with the ratio on long limit, when the trapezoidal ratio of going up base and bottom was 1: 1.85, the ratio on minor face and long limit that rolls the rectangle spring cross section of formation was 0.99.
Embodiment 3:
The spring sectional dimension that rolls formation is 20 * 16 o'clock, adopt isosceles trapezoid cross section section bar to roll, trapezoidal height is 16, midline length 20, and the ratio of last base and bottom is between 1: 1.5～1: 2, roll finish after, the side in rectangle spring cross section is 16, and all the other two edge lengths do not have slightly and wait, and minor face is 0.95～0.99 with the ratio on long limit, when the trapezoidal ratio of going up base and bottom was 1: 1.82, the ratio on minor face and long limit that rolls the rectangle spring cross section of formation was 0.99.
When the ratio of the last base of isosceles trapezoid and bottom is 1: 1.8～1: 85, roll rectangle Spring effect the best of formation.
