Description
Technical field
The utility model relates to the tools of spring, especially a kind of tools for combining tension spring.
Background technique
In numerous tension springs, there is a kind of combination tension spring 100 as shown in Figures 1 to 3, the combination tension spring 100 include comprising
One end is the outer tension spring 101 for the spring coil body 1011 that Conical Projectile spring coil portion 1010, the other end are connected with drag hook I 1012 and comprising position
In the fan-shaped closure portion 1020 outside the end of the drag hook I 1012 of spring coil body 1011 and one end and fan in spring coil body 1011
The connection of Shape closed portion 1020, the other end stretch out in the interconnecting piece connecting outside the end in Conical Projectile spring coil portion 1010 and with drag hook II 1022
1021 interior drag hook 102, wherein drag hook I 1012 and drag hook II 1022 are symmetrical structure.In general, the outer drawing of the combination tension spring 100
Spring 101 is made of numerical control automatic spring winding machine, and the feeding of steel wire is executed by the idler wheel of numerical control automatic spring winding machine when winding, and is existed
The technical issues of be；Steel wire travels forward under idler wheel rotation, at numerical control automatic spring winding machine wind spring position by several ejections
With arcuate die guide it is lower complete rolling for spring coil body 1011, and by other ejection dies complete drag hook I 1012 bending and
Bending, the control of each ejection die are completed by curve cam mechanism；And in the mistake of production spring coil body 1011 and drag hook I 1012
Cheng Zhong, the feeding of steel wire are executed by the idler wheel on numerical control automatic spring winding machine；Such feeding mechanism cannot be in production bullet
Apply certain tensile stress to steel wire during spring coil body 1011 and drag hook I 1012, causes the spring coil body for combining tension spring 100
1011 and drag hook I 1012 tensile stress it is smaller, power-displacement curve is not able to satisfy requirement.
